The author of this project found that a large number of developers based on the project for secondary development or using a large number of core code of the project without complying with the GPLv3 agreement, which seriously violates the original intention of using the GPLv3 open source agreement in this project. In view of this situation, the project adopts the source. The code delays the release strategy, to a certain extent, to curb these behaviors that do not respect open source and do not respect the labor results of others.
This project will continue to update the iterations, and continue to release the full platform binary program, providing you with powerful and convenient proxy tools.
If you have customized, business needs, please send an email to arraykeys@gmail.com
In order to provide excellent proxy functionality, please be sure to update your proxy within one month of the release of the latest version of the proxy. The official does not guarantee that the availability of the old version will be discontinued at any time after the release of the latest version, and will be discontinued at any time. Older versions will also have prompts when they start. Your use of the Program means that you agree to the update policy.
- chain-style proxy: the program itself can be a primary proxy, and if a parent proxy is set, it can be used as a second level proxy or even a N level proxy.
- Encrypted communication: if the program is not a primary proxy, and the parent proxy is also the program, then it can communicate with the parent proxy by encryption. The TLS encryption is high-intensity encryption, and it is safe and featureless.
- Intelligent HTTP, SOCKS5 proxy: the program will automatically determine whether the site which it access is blocked, if the site is blocked, the program will use parent proxy (the premise is you set up a parent proxy) to access the site. If the site isn't blocked, in order to speed up the access, the program will directly access the site and don't use parent proxy.
- The black-and-white list of domain: It is very flexible to control the way which you visite site.
- Cross platform: no mater what the os (such as Linux, windows, and even Raspberry Pi) you use, you always can use proxy well.
- Multi protocol support: the program support HTTP (S), TCP, UDP, Websocket, SOCKS5 proxy.
- The TCP/UDP port forwarding is supported.
- Nat forwarding in different network is supported: the program support TCP protocol and UDP protocol.
- SSH forwarding: HTTP (S), SOCKS5 proxy support SSH transfer, parent Linux server does not need any server, a local proxy can be happy to access the Internet.
- KCP protocol is supported: HTTP (S), SOCKS5 proxy supports the KCP protocol which can transmit data, reduce latency, and improve the browsing experience.
- The integrated external API, HTTP (S): SOCKS5 proxy authentication can be integrated with the external HTTP API, which can easily control the user's access through the external system.
- Reverse proxy: goproxy supports directly parsing the domain to proxy monitor IP, and then proxy will help you to access the HTTP (S) site that you need to access.
- Transparent proxy: with the iptables, goproxy can directly forward the 80 and 443 port's traffic to proxy in the gateway, and can realize the unaware intelligent router proxy.
- Protocol conversion: The existing HTTP (S) or SOCKS5 or ss proxy can be converted to a proxy which support HTTP (S), SOCKS5 and ss by one port, if the converted SOCKS5 and ss proxy's parent proxy is SOCKS5, which can support the UDP function.Also support powerful cascading authentication.
- Custom underlying encrypted transmission, HTTP(s)\sps\socks proxy can encrypt TCP data through TLS standard encryption and KCP protocol encryption. In addition, it also supports custom encryption after TLS and KCP. That is to say, custom encryption and tls|kcp can be used together. The internal uses AES256 encryption, and it only needs to define one password by yourself when is used.
- Low level compression and efficient transmission,The HTTP(s)\sps\socks proxy can encrypt TCP data through a custom encryption and TLS standard encryption and KCP protocol encryption, and can also compress the data after encryption. That is to say, the compression and custom encryption and tls|kcp can be used together.
- The secure DNS proxy, Through the DNS proxy provided by the local proxy, you can encrypted communicate with the father proxy to realize the DNS query of security and pollution prevention.
- Load balance,High availability,HTTP(S)\SOCKS5\SPS proxy support Superior load balance and high availability. Multiple superiors repeat -P parameters.
- Designated exporting IP,HTTP(S)\SOCKS5\SPS proxy supports the client to connect with the entry IP,Using the entry IP as the exporting IP to visit the target website.If the entry IP is the intranet IP,Exporting IP will not use entry IP
- Support speed limit. HTTP (S) \SOCKS5\SPS proxy supports speed limit.
- SOCKS5 proxy supports cascade authentication.
- Certificate parameters use base64 data. By default, the - C, - K parameters are the path of the CRT certificate and key file. If “base64://” begins, the subsequent data is thought to be Base64 encoded which will be decoded and used.
- Because for some reason, we cannot access our services elsewhere. We can build a secure tunnel to access our services through multiple connected proxy nodes.
- WeChat interface is developed locally, which is convenient to debug.
- Remote access to intranet machines.
- Play with partners in a LAN game.
- something used to be played only in the LAN, now it can be played anywhere.
- Instead of 剑内网通,显IP内网通,花生壳,frp and so on.
- ...

tips:all operations require root permissions.
0. If your VPS is linux64, you can complete the automatic installation and configuration by the following sentence.
curl -L https://raw.githubusercontent.com/snail007/goproxy/master/install_auto.sh | bash The installation is completed, the configuration directory is /etc/proxy, For more detailed usage, please refer to the manual above to further understand the functions you want to use.
If the installation fails or your VPS is not a linux64 system, please follow the semi-automatic step below:
Download address: https://github.com/snail007/goproxy/releases
cd /root/proxy/
wget https://github.com/snail007/goproxy/releases/download/v6.0/proxy-linux-amd64.tar.gz
cd /root/proxy/
wget https://raw.githubusercontent.com/snail007/goproxy/master/install.sh
chmod +x install.sh
./install.sh The following tutorial defaults system is Linux, the program is proxy and all operations require root permissions.
If the system are windows, please use proxy.exe.
The following tutorial is to introduce the useage by the command line parameters, or by reading the configuration file to get the parameters.
The specific format is to specify a configuration file by the @ symbol, for example, ./proxy @configfile.txt.
configfile.txt's format: The first line is the subcommand name, and the second line begins a new line: parameter "the parameter value"
For example, the contents of configfile.txt are as follows:
http
-t tcp
-p :33080
--foreverBy default, the log output information does not contain the number of file lines. In some cases, in order to eliminate and positione the program problem, You can use the --debug parameter to output the number of lines of code and the wrong time.
By default, the log is displayed directly on the console, and if you want to save it to the file, you can use the --log parameter.
for example, --log proxy.log, The log will be exported to proxy.log file which is easy to troubleshoot.
HTTP, TCP, UDP proxy process will communicate with parent proxy. In order to secure, we use encrypted communication. Of course, we can choose not to encrypted communication. All communication with parent proxy in this tutorial is encrypted, requiring certificate files.
1.Generate signed certificates and key files through the following commands.
./proxy keygen -C proxy
The certificate file proxy.crt and key file proxy.key will be generated under the current directory.
2.Through the following commands, use the signed certificate proxy.crt and key file proxy.key to issue new certificates: goproxy.crt and goproxy.key.
./proxy keygen -s -C proxy -c goproxy
The certificate file goproxy.crt and key file goproxy.key will be generated under the current program directory.
3.By default, the domain name in the certificate is a random domain and can be specified using the -n test.com parameter.
4.More usage:proxy keygen --help.
After the default execution of proxy, if you want to keep proxy running, you can't close the command line.
If you want to run proxy in the daemon mode, the command line can be shut down, just add the --daemon parameter at the end of the command.
for example: ./proxy http -t tcp -p "0.0.0.0:38080" --daemon
Monitor mode parameter --forever, for example: proxy http --forever,
Proxy will fork subprocess, then monitor the child process, if the subprocess exits, restarts the subprocess after 5 seconds.
This parameter, with the parameter --daemon and the log parameter --log, can guarantee that the proxy has been ran in the background and not exited accidentally.
And you can see the output log of proxy through the log file.
for example: proxy http -p ":9090" --forever --log proxy.log --daemon
When vps is behind the NAT, the network card IP on VPS is an internal network IP, and then you can add the VPS's external network IP to prevent the dead cycle by -g parameter.
Assuming that your VPS outer external network IP is 23.23.23.23, the following command sets the 23.23.23.23 through the -g parameter.
./proxy http -g "23.23.23.23"
HTTP(S)\SOCKS5\SPS proxy support Superior load balance and high availability. Multiple superiors repeat -P parameters.
Load balancing have 5 kinds of policy, It can be specified by the --lb-method parameter.:
roundrobin take turns
leastconn Using minimum connection number
leasttime Use minimum connection time
hash Use the client address to calculate a fixed superior
weight According to the weight and connection number of each superior, choose a superior
Tips:
The load balance check interval can be set by --lb-retrytime, unit milliseconds.
Load balancing connection timeout can be set by --lb-timeout, unit milliseconds.
If the load balance policy is weighted (weight), the -P format is: 2.2.2.2:3880@1,1 is the weight which is greater than 0.
If the load balance strategy is hash, the default is to select the parent based on the client address, and the parent can be selected by switching `- lb-hashtarget', using the access destination address.
http(s),sps, intranet penetration, tcp functions support the connection of superiors through intermediate third-party proxy server. The parameters are: --jumper, all the formats are as follows:
http://username:password@host:port
http://host:port
https://username:password@host:port
https://host:port
socks5://username:password@host:port
socks5://host:port
socks5s://username:password@host:port
socks5s://host:port
ss://method:password@host:port
http,socks5 represents the normal http and socks5 proxy. https,socks5s represents the http and socks5 proxy protected by tls. That is http proxy over TLS, socks over TLS.
The socks/http(s)/sps proxy supports domain name blacklists. Use the --stop parameter to specify a domain name list file. When the user connects these domains in the file, the connection will be disconnected.
The format of the blacklist domain name file is as follows:
**.baidu.com
*.taobao.com
a.com
192.168.1.1
192.168.*.*
?.qq.com
Description:
1.One domain name per line, domain name writing supports wildcards * and ?, * represents any number of characters, ? represents an arbitrary character.
2.**.baidu.com matches no matter how many levels all suffixes are .baidu.com domain name.
3.*.taobao.com The matching suffix is the third-level domain name of .taobao.com.
4. Can also be directly an IP address.
5.# at the beginning of the comment.
./proxy http -t tcp -p "0.0.0.0:38080"
Using local port 8090, assume the parent HTTP proxy is: 22.22.22.22:8080
./proxy http -t tcp -p "0.0.0.0:8090" -T tcp -P "22.22.22.22:8080"
The connection pool is closed by default. If you want to speed up access speed, -L can open the connection pool, the 10 is the size of the connection pool, and the 0 is closed.
It is not good to stability of connection pool when the network is not good.
./proxy http -t tcp -p "0.0.0.0:8090" -T tcp -P "22.22.22.22:8080" -L 10
We can also specify the black and white list files of the domain name, one line for one domain name. The matching rule is the most right-hand matching, for example, baidu.com, which matches ..baidu.com. The domain name of the blacklist is directly headed by the parent proxy, and the domain name of the white list does not go to the parent proxy.
./proxy http -p "0.0.0.0:8090" -T tcp -P "22.22.22.22:8080" -b blocked.txt -d direct.txt
HTTP first level proxy(VPS,IP:22.22.22.22)
./proxy http -t tls -p ":38080" -C proxy.crt -K proxy.key
HTTP second level proxy(local Linux)
./proxy http -t tcp -p ":8080" -T tls -P "22.22.22.22:38080" -C proxy.crt -K proxy.key
accessing the local 8080 port is accessing the proxy port 38080 above VPS.
HTTP second level proxy(local windows)
./proxy.exe http -t tcp -p ":8080" -T tls -P "22.22.22.22:38080" -C proxy.crt -K proxy.key
In your windows system, the mode of the program that needs to surf the Internet by proxy is setted up as HTTP mode, the address is 127.0.0.1, the port is: 8080, the program can go through the encrypted channel through VPS to surf on the internet.
HTTP first level proxy VPS_01,IP:22.22.22.22
./proxy http -t tls -p ":38080" -C proxy.crt -K proxy.key
HTTP second level proxy VPS_02,IP:33.33.33.33
./proxy http -t tls -p ":28080" -T tls -P "22.22.22.22:38080" -C proxy.crt -K proxy.key
HTTP third level proxy(local)
./proxy http -t tcp -p ":8080" -T tls -P "33.33.33.33:28080" -C proxy.crt -K proxy.key
Then access to the local 8080 port is access to the HTTP first level proxy which port is 38080.
We can do Basic authentication for the HTTP proxy, The authenticated username and password can be specified at the command line.
./proxy http -t tcp -p ":33080" -a "user1:pass1" -a "user2:pass2"
If you need multiple users, repeat the -a parameters.
You can also be placed in a file, which is a line, a ‘username: password’, and then specified in -F.
./proxy http -t tcp -p ":33080" -F auth-file.txt
In addition, the HTTP (s) proxy also integrates external HTTP API authentication, and we can specify a HTTP URL interface address by the --auth-url parameter.
When somebody connect the proxy, which will request this URL by GET way, with the following four parameters, and if the HTTP state code 204 is returned, the authentication is successful.
In other cases, authentication failed.
for example:
./proxy http -t tcp -p ":33080" --auth-url "http://test.com/auth.php"
When the user connecte the proxy, which will request this URL by GET way("http://test.com/auth.php"),
with user, pass, IP, and target four parameters:
http://test.com/auth.php?user={USER}&pass={PASS}&ip={IP}&target={TARGET}
user:username
pass:password
ip:user's IP,for example: 192.168.1.200
target:URL user connect to, for example: http://demo.com:80/1.html or https://www.baidu.com:80
If there is no -a or -F or --auth-url parameters, Basic authentication is closed.
By default, proxy will intelligently judge whether a domain name can be accessed. If it cannot be accessed, it will access to parent HTTP proxy.
Through --always, all HTTP proxy traffic can be coercion to the parent HTTP proxy.
./proxy http --always -t tls -p ":28080" -T tls -P "22.22.22.22:38080" -C proxy.crt -K proxy.key
Explanation: the principle of SSH transfer is to take advantage of SSH's forwarding function, which is, after you connect to SSH, you can access to the target address through the SSH proxy.
Suppose there is a vps
- IP is 2.2.2.2, ssh port is 22, ssh username is user, ssh password is demo
- The SSH private key of the user is user.key
Local HTTP (S) proxy use 28080 port,excute:
./proxy http -T ssh -P "2.2.2.2:22" -u user -A demo -t tcp -p ":28080"
Local HTTP (S) proxy use 28080 port,excute:
./proxy http -T ssh -P "2.2.2.2:22" -u user -S user.key -t tcp -p ":28080"
The KCP protocol requires a --kcp-key parameter to set a password which can encrypt and decrypt data.
Http first level proxy(VPS,IP:22.22.22.22)
./proxy http -t kcp -p ":38080" --kcp-key mypassword
Http second level proxy(os is Linux)
./proxy http -t tcp -p ":8080" -T kcp -P "22.22.22.22:38080" --kcp-key mypassword
Then access to the local 8080 port is access to the proxy's port 38080 on the VPS, and the data is transmitted through the KCP protocol.
Proxy supports not only set up a proxy through in other software, to provide services for other software, but support the request directly to the website domain to proxy monitor IP when proxy monitors 80 and 443 ports, then proxy will automatically access to the HTTP proxy access website for you.
How to use:
On the last level proxy computer, because proxy is disguised as all websites and the default port of HTTP is 80, HTTPS is 443, the proxy listens to 80 and 443 port. Parameters -p multiple addresses are separated by commas.
./proxy http -t tcp -p :80,:443
This command starts a proxy on the computer, and listens to 80 and 443 ports. It can be used as a common proxy and it can directly resolve the domain that needs proxy to the IP of the computer.
If a parent proxy exist, you can refer to the above tutorial to set up a parent. The way of use is exactly the same.
./proxy http -t tcp -p :80,:443 -T tls -P "2.2.2.2:33080" -C proxy.crt -K proxy.key
Notice:
The result of the DNS parsing of the server in which proxy is located can not affected by a custom parsing, if not, it is dead cycle.
The mode needs a certain network knowledge, if the related concepts don't understand, you must search it by yourself.
Assuming that proxy is now running on the router, the boot command is as follows:
./proxy http -t tcp -p :33080 -T tls -P "2.2.2.2:33090" -C proxy.crt -K proxy.key
Then the iptables rule is added, and the following rule is a reference rule:
#IP of parent proxy:
proxy_server_ip=2.2.2.2
#Proxy that the router runs monitor the port:
proxy_local_port=33080
#The following don't need to be modified
#create a new chain named PROXY
iptables -t nat -N PROXY
# Ignore your PROXY server's addresses
# It's very IMPORTANT, just be careful.
iptables -t nat -A PROXY -d $proxy_server_ip -j RETURN
# Ignore LANs IP address
iptables -t nat -A PROXY -d 0.0.0.0/8 -j RETURN
iptables -t nat -A PROXY -d 10.0.0.0/8 -j RETURN
iptables -t nat -A PROXY -d 127.0.0.0/8 -j RETURN
iptables -t nat -A PROXY -d 169.254.0.0/16 -j RETURN
iptables -t nat -A PROXY -d 172.16.0.0/12 -j RETURN
iptables -t nat -A PROXY -d 192.168.0.0/16 -j RETURN
iptables -t nat -A PROXY -d 224.0.0.0/4 -j RETURN
iptables -t nat -A PROXY -d 240.0.0.0/4 -j RETURN
# Anything to port 80 443 should be redirected to PROXY's local port
iptables -t nat -A PROXY -p tcp --dport 80 -j REDIRECT --to-ports $proxy_local_port
iptables -t nat -A PROXY -p tcp --dport 443 -j REDIRECT --to-ports $proxy_local_port
# Apply the rules to nat client
iptables -t nat -A PREROUTING -p tcp -j PROXY
# Apply the rules to localhost
iptables -t nat -A OUTPUT -p tcp -j PROXY- Clearing the whole chain command is iptables -F chain name, such as iptables -t NAT -F PROXY
- Deleting the specified chain that user defined command is iptables -X chain name, such as iptables -t NAT -X PROXY
- Deleting the rules of the chain command is iptables -D chain name from the selected chain, such as iptables -t nat -D PROXY -d 223.223.192.0/255.255.240.0 -j RETURN
--dns-address and --dns-ttl parameters can be used to specify DNS（--dns-address） when you use proxy to access to a domain.
they also can specify dns result cache time (--dns-ttl) which unit is second. they can avoid the interference of system DNS to proxy. cache can reduce DNS resolution time and increase access speed.
for example:
./proxy http -p ":33080" --dns-address "8.8.8.8:53" --dns-ttl 300
HTTP(s) proxy can encrypt TCP data by TLS standard encryption and KCP protocol encryption, in addition to supporting custom encryption after TLS and KCP, That is to say, custom encryption and tls|kcp can be combined to use. The internal AES256 encryption is used, and it only needs to define one password by yourself. Encryption is divided into two parts, the one is whether the local (-z) is encrypted and decrypted, the other is whether the parents (-Z) is encrypted and decrypted.
Custom encryption requires both ends are proxy. Next, we use two level example and three level example as examples:
two level example
First level VPS (ip:2.2.2.2) execution:
proxy http -t tcp -z demo_password -p :7777
Local second level execution:
proxy http -T tcp -P 2.2.2.2:777 -Z demo_password -t tcp -p :8080
through this way, When you visits the website by local proxy 8080, it visits the target website by encryption transmission with the parents proxy.
three level example
First level VPS (ip:2.2.2.2) execution:
proxy http -t tcp -z demo_password -p :7777
Second level VPS (ip:2.2.2.2) execution:
proxy http -T tcp -P 2.2.2.2:7777 -Z demo_password -t tcp -z other_password -p :8888
Local third level execution:
proxy http -T tcp -P 3.3.3.3:8888 -Z other_password -t tcp -p :8080
through this way, When you visits the website by local proxy 8080, it visits the target website by encryption transmission with the parents proxy.
HTTP(s) proxy can encrypt TCP data through TCP standard encryption and KCP protocol encryption, and can also compress data before custom encryption.
That is to say, compression and custom encryption and tls|kcp can be used together, compression is divided into two parts, the one is whether the local (-z) is compressed transmission, the other is whether the parents (-Z) is compressed transmission.
The compression requires both ends are proxy. Compression also protects the (encryption) data in certain extent. we use two level example and three level example as examples:
two level example
First level VPS (ip:2.2.2.2) execution:
proxy http -t tcp -m -p :7777
Local second level execution:
proxy http -T tcp -P 2.2.2.2:777 -M -t tcp -p :8080
through this way, When you visits the website by local proxy 8080, it visits the target website by compressed transmission with the parents proxy.
three level example
First level VPS (ip:2.2.2.2) execution:
proxy http -t tcp -m -p :7777
Second level VPS (ip:3.3.3.3) execution:
proxy http -T tcp -P 2.2.2.2:7777 -M -t tcp -m -p :8888
Local third level execution:
proxy http -T tcp -P 3.3.3.3:8888 -M -t tcp -p :8080
through this way, When you visits the website by local proxy 8080, it visits the target website by compressed transmission with the parents proxy.
HTTP (S) proxy supports superior load balance, and multiple -P parameters can be repeated by multiple superiors.
proxy http --lb-method=hash -T tcp -P 1.1.1.1:33080 -P 2.1.1.1:33080 -P 3.1.1.1:33080
proxy http --lb-method=leastconn --lb-retrytime 300 --lb-timeout 300 -T tcp -P 1.1.1.1:33080 -P 2.1.1.1:33080 -P 3.1.1.1:33080 -t tcp -p :33080
proxy http --lb-method=weight -T tcp -P 1.1.1.1:33080@1 -P 2.1.1.1:33080@2 -P 3.1.1.1:33080@1 -t tcp -p :33080
proxy http --lb-hashtarget --lb-method=leasttime -T tcp -P 1.1.1.1:33080 -P 2.1.1.1:33080 -P 3.1.1.1:33080 -t tcp -p :33080
The speed limit is 100K, which can be specified through the -l parameter, for example: 100K 2000K 1M . 0 means unlimited.
proxy http -t tcp -p 2.2.2.2:33080 -l 100K
The --bind-listen parameter open the client's ability to access the target site with an entry IP connection, using the entry IP as the exporting IP. If the entry IP is the intranet IP, the exporting IP will not use the entry IP..
proxy http -t tcp -p 2.2.2.2:33080 --bind-listen
By default, the -C and -K parameters are the paths of CRT certificates and key files, If it is the beginning of base64://, then it is considered that the data behind is Base64 encoded and will be used after decoding.
Intelligent mode setting which can be one of intelligent|direct|parent.
default:intelligent.
The meaning of each value is as follows:
--intelligent=direct, Targets that are not in blocked directly connected.
--intelligent=parent, Targets that are not in direct connect to parent proxy.
--intelligent=intelligent, Targets that are not in direct and blocked Neither can intelligently judge on whether to connetc parent proxy.

Nat forward, is divided into two versions, "multi-link version" and "multiplexed version", generally like web services Which is not a long time to connect the service recommende "multi-link version", if you want to keep long Time connection, "multiplexed version" is recommended.
- Multilink version, the corresponding subcommand is tserver,tclient,tbridge.
- Multiplexed version, the corresponding subcommand is server,client,bridge.
- the parameters and use of Multilink version and multiplexed is exactly the same.
- Multiplexed version of the server, client can open the compressed transmission, the parameter is --c.
- Server, client or both are open compression, either do not open, can not only open one.
The following tutorial uses "Multiplexing Versions" as an example to illustrate how to use it.
Nat forward consists of three parts: client-side, server-side, bridge-side; client and server take the initiative to connect the bridge to bridge.
When the user access the server side, the process is:
- Server and bridge initiative to establish a link;
- Then the bridge notifies the client to connect the bridge, and connects the intranet target port;
- Then bind the client to the bridge and client to the internal network port connection;
- Then the bridge of the client over the connection and server-side connection binding;
- The entire channel is completed;
Background:

Tips:
If there are multiple client connected to the same bridge at the same time, you need to specify different key, which can be set by --k parameter. --k must be a unique string on the same bridge.
When server is connected to bridge, if multiple client is connected to the same bridge at the same time, you need to use the --k parameter to select client.
Repeating -r parameters can expose multiple ports: -r format is "local IP: local port @clientHOST:client port".
Background:
- The company computer A provides the web service 80 port and the FTP service 21 port
- There is one VPS, which public IP is 22.22.22.22

The full format of the -r is:PROTOCOL://LOCAL_IP:LOCAL_PORT@[CLIENT_KEY]CLIENT_LOCAL_HOST:CLIENT_LOCAL_PORT
4.7.1.PROTOCOL is tcp or udp.
for example: -r "udp://:10053@:53" -r "tcp://:10800@:1080" -r ":8080@:80"
If the --udp parameter is specified, PROTOCOL is UDP by default, then -r ":8080@:80" is UDP.
If the --udp parameter is not specified, PROTOCOL is TCP by default, then -r ":8080@:80" is TCP.
4.7.2.CLIENT_KEY by default is 'default'.
for example: -r "udp://:10053@[test1]:53" -r "tcp://:10800@[test2]:1080" -r ":8080@:80"
If the --k parameter is specified, such as --k test, then -r ":8080@:80" CLIENT_KEY is 'test'.
If the --k parameter is not specified,then -r ":8080@:80"CLIENT_KEY is 'default'.
4.7.3.LOCAL_IP is empty which means LOCAL_IP is 0.0.0.0, CLIENT_LOCAL_HOST is empty which means LOCAL_IP is 127.0.0.1.
Sometimes the server or client can not directly access the external network,which need to use a HTTPS or Socks5 proxy to access the Internet. then The -J parameter can help server and client connect to the bridge through the HTTPS or Socks5 proxy.
-J param format:
https proxy:
proxy need authentication,username: username password:password
https://username:password@host:port
proxy don't need authentication
https://host:port
socks5 proxy:
proxy need authentication,username: username password:password
socks5://username:password@host:port
proxy don't need authentication
socks5://host:port
host:proxy's domain or ip port:proxy's port
./proxy help bridge
./proxy help server
./proxy help client
Tips: SOCKS5 proxy, support CONNECT, UDP protocol and don't support BIND and support username password authentication.
./proxy socks -t tcp -p "0.0.0.0:38080"
Using local port 8090, assume that the parent SOCKS5 proxy is 22.22.22.22:8080
./proxy socks -t tcp -p "0.0.0.0:8090" -T tcp -P "22.22.22.22:8080"
We can also specify the black and white list files of the domain name, one line for one domain name. The matching rule is the most right-hand matching. For example, baidu.com is ..baidu.com, the domain name of the blacklist is directly accessed by the parent proxy, and the domain name of the white list does not access to the parent proxy.
./proxy socks -p "0.0.0.0:8090" -T tcp -P "22.22.22.22:8080" -b blocked.txt -d direct.txt
SOCKS5 first level proxy(VPS,IP:22.22.22.22)
./proxy socks -t tls -p ":38080" -C proxy.crt -K proxy.key
SOCKS5 second level proxy(local Linux)
./proxy socks -t tcp -p ":8080" -T tls -P "22.22.22.22:38080" -C proxy.crt -K proxy.key
Then access to the local 8080 port is access to the proxy port 38080 above VPS.
SOCKS5 second level proxy(local windows)
./proxy.exe socks -t tcp -p ":8080" -T tls -P "22.22.22.22:38080" -C proxy.crt -K proxy.key
Then set up your windows system, the proxy that needs to surf the Internet by proxy is Socks5 mode, the address is: 127.0.0.1, the port is: 8080. the program can surf the Internet through the encrypted channel which is running on VPS.
SOCKS5 first level proxy VPS_01,IP:22.22.22.22
./proxy socks -t tls -p ":38080" -C proxy.crt -K proxy.key
SOCKS5 second level proxy VPS_02,IP:33.33.33.33
./proxy socks -t tls -p ":28080" -T tls -P "22.22.22.22:38080" -C proxy.crt -K proxy.key
SOCKS5 third level proxy(local)
./proxy socks -t tcp -p ":8080" -T tls -P "33.33.33.33:28080" -C proxy.crt -K proxy.key
Then access to the local 8080 port is access to the proxy port 38080 above the SOCKS first level proxy.
By default, proxy will intelligently judge whether a domain name can be accessed. If it cannot be accessed, it will go to parent SOCKS proxy. Through --always parameter, all SOCKS proxy traffic can be coercion to the parent SOCKS proxy.
./proxy socks --always -t tls -p ":28080" -T tls -P "22.22.22.22:38080" -C proxy.crt -K proxy.key
Explanation: the principle of SSH transfer is to take advantage of SSH's forwarding function, which is, after you connect to SSH, you can access the target address by the SSH.
Suppose there is a vps
- IP is 2.2.2.2, SSH port is 22, SSH username is user, SSH password is Demo
- The SSH private key name of the user is user.key
Local SOCKS5 proxy 28080 port, execute:
./proxy socks -T ssh -P "2.2.2.2:22" -u user -A demo -t tcp -p ":28080"
Local SOCKS5 proxy 28080 port, execute:
./proxy socks -T ssh -P "2.2.2.2:22" -u user -S user.key -t tcp -p ":28080"
Then access to the local 28080 port is to access the target address through VPS.
For socks5 proxy protocol we can use username and password authentication, username and password authentication can be specified on the command line.
./proxy socks -t tcp -p ":33080" -a "user1:pass1" -a "user2:pass2"
If you need multiple users, repeat the -a parameters.
You can also be placed in a file, which is a line, a ‘username: password’, and then specified in -F.
./proxy socks -t tcp -p ":33080" -F auth-file.txt
In addition, socks5 proxy also integrates external HTTP API authentication, we can specify a http url interface address through the --auth-url parameter,
Then when the user is connected, the proxy request this url by get way, with the following three parameters, if the return HTTP status code 204, on behalf of the authentication is successful.
In other cases, the authentication fails.
for example:
./proxy socks -t tcp -p ":33080" --auth-url "http://test.com/auth.php"
When the user is connected, the proxy will request this URL ("http://test.com/auth.php") by GET way.
With user, pass, IP, three parameters:
http://test.com/auth.php?user={USER}&pass={PASS}&ip={IP}
user:username
pass:password
ip: user's IP, for example: 192.168.1.200
If there is no -a or -F or --auth-url parameters, it means to turn off the authentication.
The KCP protocol requires a --kcp-key parameter which can set a password to encrypt and decrypt data.
HTTP first level proxy(VPS,IP:22.22.22.22)
./proxy socks -t kcp -p ":38080" --kcp-key mypassword
HTTP two level proxy(local os is Linux)
./proxy socks -t tcp -p ":8080" -T kcp -P "22.22.22.22:38080" --kcp-key mypassword
Then access to the local 8080 port is access to the proxy port 38080 on the VPS, and the data is transmitted through the KCP protocol.
--dns-address and --dns-ttl parameters can be used to specify DNS（--dns-address） when you use proxy to access to a domain.
they also can specify dns result cache time (--dns-ttl) which unit is second. they can avoid the interference of system DNS to proxy. cache can reduce DNS resolution time and increase access speed.
for example:
./proxy socks -p ":33080" --dns-address "8.8.8.8:53" --dns-ttl 300
HTTP(s) proxy can encrypt TCP data by TLS standard encryption and KCP protocol encryption, in addition to supporting custom encryption after TLS and KCP, That is to say, custom encryption and tls|kcp can be combined to use. The internal AES256 encryption is used, and it only needs to define one password by yourself. Encryption is divided into two parts, the one is whether the local (-z) is encrypted and decrypted, the other is whether the parents (-Z) is encrypted and decrypted. Custom encryption requires both ends are proxy. Next, we use two level example and three level example as examples:
two level example
First level VPS (ip:2.2.2.2) execution:
proxy socks -t tcp -z demo_password -p :7777
Local second level execution:
proxy socks -T tcp -P 2.2.2.2:777 -Z demo_password -t tcp -p :8080
through this way, When you visits the website by local proxy 8080, it visits the target website by encryption transmission with the parents proxy.
three level example
First level VPS (ip:2.2.2.2) execution:
proxy socks -t tcp -z demo_password -p :7777
Second level VPS (ip:2.2.2.2) execution:
proxy socks -T tcp -P 2.2.2.2:7777 -Z demo_password -t tcp -z other_password -p :8888
Local third level execution:
proxy socks -T tcp -P 3.3.3.3:8888 -Z other_password -t tcp -p :8080
through this way, When you visits the website by local proxy 8080, it visits the target website by encryption transmission with the parents proxy.
HTTP(s) proxy can encrypt TCP data through TCP standard encryption and KCP protocol encryption, and can also compress data before custom encryption. That is to say, compression and custom encryption and tls|kcp can be used together, compression is divided into two parts, the one is whether the local (-z) is compressed transmission, the other is whether the parents (-Z) is compressed transmission. The compression requires both ends are proxy. Compression also protects the (encryption) data in certain extent. we use two level example and three level example as examples:
two level example
First level VPS (ip:2.2.2.2) execution:
proxy socks -t tcp -m -p :7777
Local second level execution:
proxy socks -T tcp -P 2.2.2.2:777 -M -t tcp -p :8080
through this way, When you visits the website by local proxy 8080, it visits the target website by compressed transmission with the parents proxy.
three level example
First level VPS (ip:2.2.2.2) execution:
proxy socks -t tcp -m -p :7777
Second level VPS (ip:3.3.3.3) execution:
proxy socks -T tcp -P 2.2.2.2:7777 -M -t tcp -m -p :8888
Local third level execution:
proxy socks -T tcp -P 3.3.3.3:8888 -M -t tcp -p :8080
through this way, When you visits the website by local proxy 8080, it visits the target website by compressed transmission with the parents proxy.
SOCKS proxy supports the load balancing of superior authorities, and the -P parameters can be repeated by multiple superiors.

The speed limit is 100K, which can be specified through the -l parameter, for example: 100K 2000K 1M . 0 means unlimited.
proxy socks -t tcp -p 2.2.2.2:33080 -l 100K
The - bind-listen parameter opens the client's ability to access the target site with an entry IP connection, using the entry IP as the exporting IP. If the entry IP is the intranet IP, the exporting IP will not use the entry IP..
proxy socks -t tcp -p 2.2.2.2:33080 --bind-listen
SOCKS5 supports cascading authentication, and -A can set up parents proxy's authentication information..
parents proxy:
proxy socks -t tcp -p 2.2.2.2:33080 -a user:pass
localhost:
proxy socks -T tcp -P 2.2.2.2:33080 -A user:pass -t tcp -p :33080
By default, the -C and -K parameters are the paths of CRT certificates and key files,
If it is the beginning of base64://, then it is considered that the data behind is Base64 encoded and will be used after decoding.
Intelligent mode setting which can be one of intelligent|direct|parent.
default:intelligent.
The meaning of each value is as follows:
--intelligent=direct, Targets that are not in blocked directly connected.
--intelligent=parent, Targets that are not in direct connect to parent proxy.
--intelligent=intelligent, Targets that are not in direct and blocked Neither can intelligently judge on whether to connetc parent proxy.

The proxy protocol conversion use the SPS subcommand, SPS itself does not provide the proxy function, just accept the proxy request and then converse protocol and forwarded to the existing HTTP (s) or Socks5 proxy. SPS can use existing HTTP (s) or Socks5 proxy converse to support HTTP (s) and Socks5 HTTP (s) proxy at the same time by one port, and proxy supports forward and reverse proxy (SNI), SOCKS5 proxy which is also does support UDP when parent is Socks5. in addition to the existing HTTP or Socks5 proxy, which supports TLS, TCP, KCP three modes and chain-style connection. That is more than one SPS node connection can build encryption channel.
the following methods are supported by ss : aes-128-cfb , aes-128-ctr , aes-128-gcm , aes-192-cfb , aes-192-ctr , aes-192-gcm , aes-256-cfb , aes-256-ctr , aes-256-gcm , bf-cfb , cast5-cfb , chacha20 , chacha20-ietf , chacha20-ietf-poly1305 , des-cfb , rc4-md5 , rc4-md5-6 , salsa20 , xchacha20

./proxy sps -S http -T kcp -P 127.0.0.1:8080 -t tcp -p :18080 --kcp-key demo123 -h aes-192-cfb -j pass
Suppose there is a common Socks5 proxy: 127.0.0.1:8080, now we turn it into a common proxy that supports HTTP (s), Socks5 and ss at the same time, and the local port after transformation is 18080. ss's Encryption method is aes-192-cfb and its password is pass.
command：
./proxy sps -S socks -T tcp -P 127.0.0.1:8080 -t tcp -p :18080 -h aes-192-cfb -j pass
Suppose there is a TLS Socks5 proxy: 127.0.0.1:8080. Now we turn it into a common proxy that supports HTTP (s), Socks5 and ss at the same time. The local port after transformation is 18080, TLS needs certificate file. ss's Encryption method is aes-192-cfb and its password is pass.
command：
./proxy sps -S socks -T tls -P 127.0.0.1:8080 -t tcp -p :18080 -C proxy.crt -K proxy.key -h aes-192-cfb -j pass
Suppose there is a KCP Socks5 proxy (password: demo123): 127.0.0.1:8080, now we turn it into a common proxy that supports HTTP (s), Socks5 and ss at the same time, and the local port after transformation is 18080. ss's Encryption method is aes-192-cfb and its password is pass.
command：
./proxy sps -S socks -T kcp -P 127.0.0.1:8080 -t tcp -p :18080 --kcp-key demo123 -h aes-192-cfb -j pass
SPS support the SS protocol with the local authorities. The parent proxy can be SPS or standard SS services.
By default, SPS provides three proxies, HTTP (S), SOCKS5 and SPS. the converted SOCKS5 and SS support UDP when the parent proxy is SOCKS5.
Suppose there is an ordinary SS or SPS proxy (open SS, encryption: aes-256-cfb, password: Demo)：127.0.0.1:8080,Now we turn it into a common proxy that supports both http (s) and Socks5 and ss. The converted local port is 18080, and the converted ss encryption mode is aes-192-cfb, ss password:pass.
command：
./proxy sps -S socks -T kcp -P 127.0.0.1:8080 -t tcp -p :18080 --kcp-key demo123 ./proxy sps -S ss -H aes-256-cfb -J pass -T tcp -P 127.0.0.1:8080 -t tcp -p :18080 -h aes-192-cfb -j pass.
It is mentioned above that multiple SPS nodes can be connected to build encrypted channels, assuming you have the following VPS and a PC.
vps01：2.2.2.2
vps02：3.3.3.3
Now we want to use PC and vps01 and vps02 to build an encrypted channel. In this example, TLS is used. KCP also supports encryption in addition to TLS. and accessing to local 18080 port on PC is accessing to the local 8080 ports of vps01.
First, on vps01 (2.2.2.2), we run a HTTP (s) proxy that only can be accessed locally,excute：
./proxy -t tcp -p 127.0.0.1:8080
Then run a SPS node on vps01 (2.2.2.2),excute：
./proxy -S http -T tcp -P 127.0.0.1:8080 -t tls -p :8081 -C proxy.crt -K proxy.key
Then run a SPS node on vps02 (3.3.3.3),excute：
./proxy -S http -T tls -P 2.2.2.2:8081 -t tls -p :8082 -C proxy.crt -K proxy.key
Then run a SPS node on the PC,excute：
./proxy -S http -T tls -P 3.3.3.3:8082 -t tcp -p :18080 -C proxy.crt -K proxy.key
finish.
In general, listening one port is enough, but if you need to monitor 80 and 443 ports at the same time as a reverse proxy, the -p parameter can support it.
The format is：-p 0.0.0.0:80,0.0.0.0:443, Multiple bindings are separated by a comma.
SPS supports HTTP(s)\socks5 proxy authentication, which can concatenate authentication, there are four important information:
1:Users send authentication informationuser-auth.
2:Local authentication information set uplocal-auth.
3:Set the authentication information accessing to the father proxyparent-auth.
4:The final authentication information sent to the father proxyauth-info-to-parent.
The relationship between them is as follows:
| user-auth | local-auth | parent-auth | auth-info-to-paren |
|---|---|---|---|
| yes/no | yes | yes | come from parent-auth |
| yes/no | no | yes | come from parent-auth |
| yes/no | yes | no | no |
| no | no | no | no |
| yes | no | no | come from user-auth |
For SPS proxy we can have username and password to authenticate, and the authentication username and password can be specified on the command line
./proxy sps -S http -T tcp -P 127.0.0.1:8080 -t tcp -p ":33080" -a "user1:pass1" -a "user2:pass2"
if there are multiple users, repeat the -a parameters.
It can also be placed in a file, which is a line to a username: password, and then specified in -F parameter.
./proxy sps -S http -T tcp -P 127.0.0.1:8080 -t tcp -p ":33080" -F auth-file.txt
If the father proxy is authenticated, the lower level can set the authentication information through the -A parameters, such as:
father proxy:./proxy sps -S http -T tcp -P 127.0.0.1:8080 -t tcp -p ":33080" -a "user1:pass1" -a "user2:pass2"
local proxy:./proxy sps -S http -T tcp -P 127.0.0.1:8080 -A "user1:pass1" -t tcp -p ":33080"
In addition, SPS proxy, local authentication is integrated with external HTTP API authentication, and we can specify a HTTP URL interface address through the --auth-url parameter,
Then, when there is a user connection, proxy will request this URL by GET way, with the following four parameters, and if the HTTP state code 204 is returned, the authentication is successful.
Other cases consider authentication failure.
for example:
./proxy sps -S http -T tcp -P 127.0.0.1:8080 -t tcp -p ":33080" --auth-url "http://test.com/auth.php"
When the user is connected, proxy will request this URL by GET way("http://test.com/auth.php"),
Four parameters with user, pass, IP, and target:
http://test.com/auth.php?user={USER}&pass={PASS}&ip={IP}&target={TARGET}
user:username
pass:password
ip:user's ip,for example:192.168.1.200
target: if the client is the HTTP (s) proxy request, this represents the complete URL of the request, and the other cases are empty.
If there is no -a or -F or --auth-url parameters, local authentication is closed.
If there is no -A parameter, the connection to the father proxy does not use authentication.
Set individual authentication information
If there are multiple different superiors, and their passwords are different, then you can set authentication information for each superior.
At the same time, you can also set a global authentication information with the -A parameter. If a higher level does not set the authentication information separately, the globally set authentication information is used.
The authentication information is written together with the superior.
The format is: a:b@2.2.2.2:33080#1
Description:
User is a password is b, if the user name and password protection special symbols can be encoded using urlencode
If it is ss, then a is the encryption method, b is the password, for example: aes-192-cfb:your_pass
@ is the interval symbol. If there is authentication information, there must be @, no authentication information can be omitted @
2.2.2.2: 33080 is the superior address
#1 is the setting weight, it can be omitted. For details, please refer to the manual *** weight section ***
Set protocol type for separate authentication information
If there are multiple different superiors, and their passwords and transmission protocols are the same, then the protocol type of the authentication information can be set for each superior.
At the same time, a global authentication information protocol type can be set with the -S and -T parameters. If a superior does not have a separate authentication information protocol type, the globally set authentication information protocol type is used.
The type of authentication information protocol is written together with the superior.
The format is: http://a:b@2.2.2.2:33080#1
Description:
http:// is the protocol type, possible types and contains the following:
http is equivalent to -S http -T tcp
https is equivalent to -S http -T tls --parent-tls-single , which is http(s) proxy over TLS
https2 is equivalent to -S http -T tls
socks5 is equivalent to -S socks -T tcp
socks5s is equivalent to -S socks -T tls --parent-tls-single , which is socks over TLS
socks5s2 is equivalent to -S socks -T tls
ss is equivalent to -S ss -T tcp
httpws is equivalent to -S http -T ws
httpwss is equivalent to -S http -T wss
socks5ws is equivalent to -S socks -T ws
socks5wss is equivalent to -S socks -T wss
HTTP(s) proxy can encrypt TCP data by TLS standard encryption and KCP protocol encryption, in addition to supporting custom encryption after TLS and KCP, That is to say, custom encryption and tls|kcp can be combined to use. The internal AES256 encryption is used, and it only needs to define one password by yourself. Encryption is divided into two parts, the one is whether the local (-z) is encrypted and decrypted, the other is whether the parents (-Z) is encrypted and decrypted.
Custom encryption requires both ends are proxy. Next, we use two level example and three level example as examples:
Suppose there is already a HTTP (s) proxy:6.6.6.6:6666
two level example
First level VPS (ip:2.2.2.2) execution:
proxy sps -S http -T tcp -P 6.6.6.6:6666 -t tcp -z demo_password -p :7777
Local second level execution:
proxy sps -T tcp -P 2.2.2.2:777 -Z demo_password -t tcp -p :8080
through this way, When you visits the website by local proxy 8080, it visits the target website by encryption transmission with the parents proxy.
three level example
First level VPS (ip:2.2.2.2) execution:
proxy sps -S http -T tcp -P 6.6.6.6:6666 -t tcp -z demo_password -p :7777
Second level VPS (ip:2.2.2.2) execution:
proxy sps -T tcp -P 2.2.2.2:7777 -Z demo_password -t tcp -z other_password -p :8888
Local third level execution:
proxy sps -T tcp -P 3.3.3.3:8888 -Z other_password -t tcp -p :8080
through this way, When you visits the website by local proxy 8080, it visits the target website by encryption transmission with the parents proxy.
HTTP(s) proxy can encrypt TCP data through TCP standard encryption and KCP protocol encryption, and can also compress data before custom encryption.
That is to say, compression and custom encryption and tls|kcp can be used together, compression is divided into two parts, the one is whether the local (-z) is compressed transmission, the other is whether the parents (-Z) is compressed transmission.
The compression requires both ends are proxy. Compression also protects the (encryption) data in certain extent. we use two level example and three level example as examples:
two level example
First level VPS (ip:2.2.2.2) execution:
proxy sps -t tcp -m -p :7777
Local second level execution:
proxy sps -T tcp -P 2.2.2.2:777 -M -t tcp -p :8080
through this way, When you visits the website by local proxy 8080, it visits the target website by compressed transmission with the parents proxy.
three level example
First level VPS (ip:2.2.2.2) execution:
proxy sps -t tcp -m -p :7777
Second level VPS (ip:3.3.3.3) execution:
proxy sps -T tcp -P 2.2.2.2:7777 -M -t tcp -m -p :8888
Local third level execution:
proxy sps -T tcp -P 3.3.3.3:8888 -M -t tcp -p :8080
through this way, When you visits the website by local proxy 8080, it visits the target website by compressed transmission with the parents proxy.
By default, SPS's port supports two proxy protocols, http (s) and socks5, and we can disable a protocol with parameters.
for example:
1.Disable the HTTP (S) proxy, retaining only the SOCKS5 proxy,parameter:--disable-http.
proxy sps -T tcp -P 3.3.3.3:8888 -M -t tcp -p :8080 --disable-http
1.Disable the SOCKS5 proxy, retaining only the HTTP (S) proxy,parameter:--disable-socks.
proxy sps -T tcp -P 3.3.3.3:8888 -M -t tcp -p :8080 --disable-http
Suppose there has a SOCKS5 parent proxy:
proxy socks -p 2.2.2.2:33080 -z password -t tcp
SPS lower speed limit 100K
proxy sps -S socks -P 2.2.2.2:33080 -T tcp -Z password -l 100K -t tcp -p :33080
It can be specified through the -l parameter, for example: 100K 2000K 1M . 0 means unlimited.
The - bind-listen parameter opens the client's ability to access the target site with an entry IP connection, using the entry IP as the exporting IP. If the entry IP is the intranet IP, the exporting IP will not use the entry IP.
proxy sps -S socks -P 2.2.2.2:33080 -T tcp -Z password -l 100K -t tcp --bind-listen -p :33080
By default, the -C and -K parameters are the paths of CRT certificates and key files,
If it is the beginning of base64://, then it is considered that the data behind is Base64 encoded and will be used after decoding.
The sps function does not force a parent to be specified. When the parent is empty, the sps itself can complete the full proxy function. If the parent is specified, the superior connection target is used as before.
The following command is to open the http(s)\ss\socks service with one port.
./proxy sps -p :33080
The HTTP(S)\SOCKS5\SS proxy function provided by the SPS function, the client connects to the specified "target" through the SPS proxy. This "target" is generally a website or an arbitrary TCP address. The website "target" is generally foo.com:80, foo.com:443, and sps supports the use of the --rewrite parameter to specify a ‘target’ redirection rule file to redirect the target, and the client is non-perceived. For example, if you redirect to "target": demo.com:80 to 192.168.0.12:80, then the client visits the website demo.com, in fact, the website service provided by 192.168.0.12. Example of a "target" redirection rule file:
#example
Www.a.com:80 10.0.0.2:8080
** .b.com: 80 10.0.0.2:80
192.168.0.11:80 10.0.0.2:8080
./proxy help sps
Many functions of the proxy support the KCP protocol, and all the functions that can use the KCP protocol support the configuration parameters introduced here.
So here is a unified introduction to the KCP configuration parameters.
The number of KCP configuration parameters is 17, you don't have to set up them. they all have the default value, if for the best effect,
You need to configure the parameters according to your own network conditions. Due to the complexity of KCP configuration, a certain network basic knowledge is required,
If you want to get a more detailed configuration and explanation of the KCP parameters, search for yourself. The command line name for each parameter, as well as the default and simple functions, are described as follows：
--kcp-key="secrect" pre-shared secret between client and server
--kcp-method="aes" encrypt/decrypt method, can be: aes, aes-128, aes-192, salsa20, blowfish,
twofish, cast5, 3des, tea, xtea, xor, sm4, none
--kcp-mode="secrect" profiles: fast3, fast2, fast, normal, manual
--kcp-mtu=1350 set maximum transmission unit for UDP packets
--kcp-sndwnd=1024 set send window size(num of packets)
--kcp-rcvwnd=1024 set receive window size(num of packets)
--kcp-ds=10 set reed-solomon erasure coding - datashard
--kcp-ps=3 set reed-solomon erasure coding - parityshard
--kcp-dscp=0 set DSCP(6bit)
--kcp-nocomp disable compression
--kcp-acknodelay be carefull! flush ack immediately when a packet is received
--kcp-nodelay=0 be carefull!
--kcp-interval=50 be carefull!
--kcp-resend=0 be carefull!
--kcp-nc=0 be carefull! no congestion
--kcp-sockbuf=4194304 be carefull!
--kcp-keepalive=10 be carefull!
DNS is known as the service provided by UDP port 53, but with the development of the network, some well-known DNS servers also support TCP mode dns query, such as Google's 8.8.8.8, the DNS anti-pollution server principle of the proxy is to start a proxy DNS proxy locally. Server, which uses TCP to perform dns query through the superior agent. If it communicates with the superior agent, it can perform secure and pollution-free DNS resolution. It also supports independent services, concurrent parsing, and enhanced enhanced hosts file function to support flexible concurrent parsing and forwarding.
Dns resolution order:
- Use the parameter --hosts to parse.
- If the domain name to be resolved is not found in 1, it is parsed using the parameter --forward rule.
- The domain name to be resolved is not found in 1 and 2, and the default --default parsing is used. The default default behavior parameter values are three: proxy, direct, and system. The three parameter values are explained as follows: Proxy: The domain name is resolved by the dns server specified by the -q parameter. Direct: Connect to the dns server specified by the -q parameter to resolve the domain name through the local network. System: resolves the domain name through the system dns.
Tip: 1.The host file format specified by the --hosts parameter is the same as the system hosts file, and the domain name supports wildcards. You can refer to the hosts file. 2.The parsing forwarding rule file specified by the --forward parameter can be referenced to the resolve.rules file. The domain name supports wildcards. It supports multiple dns servers for each domain name to be parsed concurrently. The resolution of the fastest resolution is used. 3.The -q parameter can specify multiple remote dns servers to perform concurrent parsing. Whoever resolves the fastest parsing success, the default is: 1.1.1.1, 8.8.8.8, 9.9.9.9, multiple comma-separated. For example, you can also bring ports: 1.1.1.1, 8.8.8.8#53, 9.9.9.9
If you start a standalone service, you don't need a parent:
Can execute:
proxy dns --default system -p :5353
Or
proxy dns --default direct -p :5353
