Real Advenced TFTP Daemon

Because ATFTPD is not advenced enought

capability

• manage per subnet configuration
• manage per subnet basedir with aliasing
• manage per subnet maximum simultanous connexion (due to how the protocole is designed it's not possible to set it using external tool like firewall rule)
• manage blksize option (allow acknolage lower value)

usage

src/main.py --config=config.json [--foreground]

config file

below a sample configuration file with default parameter

{
    "bind" : "0.0.0.0",
    "port" : 69,
    "timeout" : 5,
    "retry" : 5,
    "pidfile" : "ratftpd.pid", 
    "maxConn" : 65535,
    "blksize" : None,
    "basepath" : "tftproot",
    "pathalias" : {
        "foo" : "foo",
        "bar" : "bar"
    },
    "user" : "root",
    "group" : "root",
    "network" : [
        {
            "network" : "0.0.0.0/0",
            "blksize" : None,
            "basepath" : "/foo/bar/foobar",
            "timeout" : 5,
            "retry" : 5,
            "maxConn" : 65535
        },
        {
            "network" : "192.168.0.0/22",
            "blksize" : 2048,
            "alias" : "foo",
            "timeout" : 10,
            "retry" : 3,
            "maxConn" : 19
        },
        {
            "network" : "192.168.2.128/25",
            "blksize" : 1024,
            "alias" : "bar",
            "maxConn" : 5
        }
    ]
}

• pidfile should be set preferentialy on absolute path
• if blksize is None, no filter is applyed on requested blksize by the client, otherize min(clietBlkzie, blksize) is acknoleaged
• basepath can be relative of absolute, please use absolute path preferentialy
• if daemon is run on non-root user, "user" and "group" option is silenty ignored

path aliasing

On network configuration you can use path aliasing

you should define a relative path from the basepath. on the exemple above the path alias foo is resolved as tftproot/foo

On network, you can use basepath or alias option, be carefull because only one of theses option should be used.

configuration default

Defaut value for network is propaged according to the mask size.

If you overload a configuration on lower network, the configuration for this network is used

max conn validation

The maximum connexion validation should be validate on all the path.

if you define 192.168.0.0/22 with "maxConn": 19 and 192.168.2.128/25 with "maxConn" = 5 you should have a slot free on the two network.
