Can't Get ruTorrent To Connect to rTorrent Using Basic Instructions #2730

I'm pulling my hair out trying to get my ruTorrent to connect to rTorrent. I just upgraded to Ubuntu 24.10 and I'm trying to transfer everything over. I'm starting with the absolute basics with basic configuration.

I installed rtorrent via sudo apt-get install rtorrent Version is 0.9.8. I downloaded .rtorrent.rc from https://github.com/rakshasa/rtorrent/wiki/CONFIG-Template by copy and pasting the default config. rTorrent works and is running. However, when running ss -ltnp I only see

LISTEN 0 4096 *:55556 *:* users:(("rtorrent main",pid=21693,fd=14))

I don't see any port 5000 SCGI listening port.
I went to https://github.com/Novik/ruTorrent/wiki/WebSERVER. I installed apache2 via sudo apt-get install apache2 . I installed libapache2-mod-php, php-mbstring, php-cgi, php-fpm. I can't remember what else I installed, the instructions aren't super clear.
When running sudo apt-get install libapache2-mod-scgi I'm told E: Package 'libapache2-mod-scgi' has no installation candidate. It looks like scgi is deprecated. I followed the instructions here and downloaded the deb of 1.13 for amd64. Hopefully this is ok.
I ran sudo a2enmod scgi and the same for php8.3. It says they are enabled. I edited /etc/apache2/sites-enabled/000-default.conf and add SCGIMount /RPC2 127.0.0.1:5000 inside the <VirtualHost *:80> directive. I ran sudo a2ensite 000-default.conf. It's enabled. I restart my webserver constantly with sudo systemctl restart apache2.service. I check phpinfo() and can see mbstring and mod_scgi.
I download the stable ruTorrent-5.0.0 tar.gz. I move it over to /var/www/html and sudo tar -zxvf ruTorrent-5.0.0.tar.gz. I change ownership of the files from root to www-data using sudo chown -R www-data:www-data ruTorrent-5.0.0 and rename to just ruTorrent. In config.php the scgi_port and scgi_host is 5000 and 127.0.0.1 so I don't touch anything. I go to 127.0.0.1/ruTorrent. The interface pops up, but says Torrent list not available yet, connection to rTorrent not established. I check /var/log/apache2/error.log and everything there looks fine. I try to check /tmp/errors.log for the ruTorrent log but that file doesn't exist.
I try Mod Proxy SCGI. I edited /etc/apache2/sites-enabled/000-default.conf and replaced the old SCGIMount /RPC2 127.0.0.1:5000 with ProxyPass /RPC2 scgi://localhost:5000/ and sudo a2enmod proxy_scgi and restarted the server. I refresh ruTorrent and it says the same thing.
I try the unix socket. I replace ProxyPass /RPC2 scgi://localhost:5000/ with ProxyPass /RPC2 unix:/tmp/rpc.socket|scgi://127.0.0.1 and edited config.php by commenting out scgi_host and scgi_port and uncommenting the socket ($scgi_port = 0; $scgi_host = "unix:///tmp/rpc.socket";) Still doesn't work.

Without going into all the details I've tried lighttpd and nginx as well even though I'm less familiar with those. I haven't tried the HTTPRPC plugin, I'm not sure how to install that. Doesn't anybody have any ideas? I'm surely missing something simple.

I think it might be something with scgi. When I tried xmlrpc http://127.0.0.1/RPC2 view.list I get an error message and my apache log says

[Sat Oct 12 18:24:08.973154 2024] [:error] [pid 44089:tid 44089] (111)Connection refused: [client 127.0.0.1:58788] scgi: scgi: can't connect to server

error message:

Ok, I installed lighttpd again with RPC host and port and I think I made progress. Now it's giving me this error when I launch ruTorrent:

I'm getting some weird 403 Forbidden when it seems I'm accessing my php files, but when I access index.lighttpd.html in the web root directory I can read that file just fine.

Hello, I would recommend the swizzin installation script on Ubuntu 24.04 LTS. This type of installation method is complex and time consuming. You can be up and running in 10 minutes on rTorrent 0.10.0 with ruTorrent v5.0. https://github.com/swizzin/swizzin

Ty stickz, I can use the script as a last resort, but I'd like to figure out how this works.

I'm trying now the nginx route. I installed nginx and php-fpm using this guide. I can load ruTorrent and it seems to connect to rTorrent, but it's giving me the following

Bad response from server: (500 [error,getplugins]) Internal Server Error

Checking nginx error logs I see:

2024/10/13 15:52:41 [error] 212761#212761: *84 FastCGI sent in stderr: "PHP message: PHP Fatal error: Uncaught Error: Call to undefined function exec() in /var/www/html/ruTorrent/php/which.php:30

When I check phpinfo() I see under Core

disable_functions exec,passthru,shell_exec,system exec,passthru,shell_exec,system

Yet when I check Loaded Configuration File /etc/php/8.3/fpm/php.ini

; This directive allows you to disable certain functions.

; https://php.net/disable-functions
disable_functions =

disable_functions is blank... but for some reason my exec function is disabled..

Ah, I had

php_admin_value[disable_functions] = exec,passthru,shell_exec,system

set in one of my conf files in the /etc/php/8.3/fpm/pool.d/ directory. Will have to look further.

Error message:

2024/10/13 21:54:21 [crit] 31604#31604: *1 connect() to unix:/var/run/php8.3-fpm.sock failed (2: No such file or directory) while connecting to upstream, client: 127.0.0.1, server: _, request: "GET /ruTorrent/php/getplugins.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php8.3-fpm.sock:", host: "127.0.0.1", referrer: "http://127.0.0.1/ruTorrent/"

Looks like some permissions issue.

It's definitely a file permission issue. The user running the web server (usually www-data) will need to have read access to the unix domain socket, which is created and owned by the user running rtorrent. If you add www-data to rtorrent user's user group in order for it to be able to read the socket, you'll need to reboot the system to take the change into effect.

Does rTorrent create the socket or php-fpm? It seems like php-fpm creates the socket and the one I'm running is in /var/run/php/php8.3-fpm.sock.

t1@TOWERLIN:/var/run/php$ ls -lsa
total 4
0 drwxr-xr-x 2 www-data www-data 100 Oct 14 14:26 .
0 drwxr-xr-x 40 root root 1000 Oct 14 14:26 ..

0 lrwxrwxrwx 1 root root 30 Oct 14 14:26 php-fpm.sock -> /etc/alternatives/php-fpm.sock

The socket is owned by www-data as is the process php-fpm and nginx.

The user running rtorrent is t1. He is already a member of www-data.

t1@TOWERLIN:/var/run/php$ sudo adduser t1 www-data
info: The user `t1' is already a member of `www-data'.

In /etc/php/8.3/fpm/pool.d there is only one conf now, www.conf. Some excerpts include,

[www]
user = www-data
group = www-data
listen = /run/php/php8.3-fpm.sock
listen.owner = www-data
listen.group = www-data

There's a lot of moving pieces. I'm sorry I don't have a fuller understanding. How does rtorrent know where to use the socket?

Also, my logs rotated. I'm not getting any errors anymore in /var/log/nginx/error.log when I go to http://127.0.0.1/ruTorrent but it's saying "Torrent list not yet available, connection to rTorrent not established."

Yeah I'm just not understanding all the connections. I think I just have to get rtorrent to connect to the socket now.

So it looks like rtorrent opens a socket here (from .rtorrent.rc)

network.scgi.open_local = (cat,(session.path),rpc.socket)

which is /home/t1/rtorrent/.session/rpc.socket

When I change this to network.scgi.open_local = /run/php/php8.3-fpm.sock it says rtorrent: Error in option file: ~/.rtorrent.rc:111: Could not prepare socket for listening: Address already in use

I guess I don't understand how the sockets work.

just a guy reading along taking an interest & willing to help if i can.
i know you installed rtorrent & say it was running but you didnt mention how you set it running & mention no listening port.
did you run rtorrent in screen yea? screen -dmS rtorrent rtorrent
is it still running ? screen -ls

worth checking

just seen your last comment..

weird i dont have network.scgi.open_local in my rc
only network.scgi.open related option i have is network.scgi.open_port = 127.0.0.1:5002

Ah, I had it uncommented when it's normally commented. I'm not sure what configuration I need so rtorrent is setup to talk to the webserver/rutorrent. Docs seems to say to go here so I downloaded the basic .rtorrent.rc from there and just trying to work from a default installation. I'm trying to start from basics. Just a simple rtorrent, then install web server, then drop in rutorrent, then install what I need to get the webserver to talk to rtorrent.

I'm not running screen or anything advanced yet. I'm just running rtorrent from my terminal.

There seems to be a lot of different options to run rutorrent through the webserver and get it to talk to rtorrent. I'm just trying to find one that works lol. I thought I would know enough, but evidently I need to know more to understand and get the job done. I used to just use apache and scgi on ubuntu 15.10, but that doesn't seem to work anymore, or at least I'm not up to date on the new changes.

I tried going the scgi route with rpc host and port, but I had problems. I can try again, but without jumping all over the place I'd like to go step by step and understand each step and work things through.

i feel ya m8, its pretty darn interesting stuff init hahaa one reason i enjoy reading & learning here.

I seemed to have fixed the problem by making sure I have

network.scgi.open_port = 127.0.0.1:5000 in my .rtorrent.rc file. (I commented out #network.scgi.open_local just in case)

Adding

location /RPC2 {
include scgi_params;
scgi_pass 127.0.0.1:5000;
}

In my /etc/nginx/sites-enabled/default .

Now I'm getting

[19.10.2024 16:10:11] _cloudflare: Plugin will not work. Webserver user can't access external program (python).
[19.10.2024 16:10:11] rutracker_check: Plugin will not work. Webserver user must have execute access to the rtorrent session directory (/home/t1/rtorrent/.session/).
[19.10.2024 16:10:11] dump: Plugin will not work. rTorrent user can't access external program (dumptorrent).
[19.10.2024 16:10:11] mediainfo: Plugin will not work. rTorrent user can't access external program (mediainfo).
[19.10.2024 16:10:11] spectrogram: Plugin will not work. rTorrent user can't access external program (sox).
[19.10.2024 16:10:12] Unpack plugin: rTorrent user can't access 'unrar' program.

I had the same error for ffmpeg, but I solved it by simply installing it so that seems to be the fix. So that's what I'm going to do and it should fix my problems. I think I might ignore the rutracker_check webserver permission issue since I don't use it. Hopefully it won't effect my usage.

If I have time I may write a tutorial. We shall see if everything works.
