Proper support to choose what NIC to be using

[blixten85]

I would like to see a feature where i can in a proper way specify a network card or an ip-adress. (NIC preferd)

Can you provide an example of what you mean? rTorrent can already bind to a specific IP address with network.bind_address.set, and in general for Linux you'd normally create an IP on the NIC you want and attach bind the process's socket to that.

Aha ok, i can setup the VPN client in my router, and bind wlan0 ip there.

RuTorrent seems to be reporting my external WAN ip instead of the VPN ip when doing this though, how can i make RuTorrent report the correct ip in the GUI?

[kannibalox]

If you want ruTorrent to go out through the VPN, you'll have to bind it (or the webserver running it) to the same IP as rTorrent. Unfortunately I don't know the setting for that off the top of my head, you might want to check their documentation.

If you mean that rTorrent is reporting the wrong address to trackers, you can use the network.local_address.set command to set the correct external IP.

Ok, thank you.

No i ment RuTorrent. But i appreciate the network.local_address.set setting :)

i have tried this but it does not always seem to work

`# Set an interface with IPv4 address to bind to: [eth0|tun0]
method.insert = cfg.interface.bind, string|const|private, (cat,"wg0")

Get IPv4 address of a given interface

method.insert = get_interface_ipv4_address, simple|private,
"execute.capture=bash,-c,"$cat=\"echo -n $(ip -o -4 addr show \",$argument.0=,\" | grep -Po 'inet \\\\\K[\\\\\d.]+')\"""

The IP address the listening socket and outgoing connections is bound to. (bind)

schedule2 = set_bind_address, 0, 0,
"branch=((cfg.interface.bind)),
((network.bind_address.set,(get_interface_ipv4_address,(cfg.interface.bind))))"`

is this correct or are there any updated versions of this?

This changed somewhat in some version of linux that I can't recall but does require bash. You can use the below:

method.insert = get_interface_ipv4_address, simple|private, \
"execute.capture=bash, -c, \"$cat=\\\"echo -n \$(ip -o -4 addr show \\\",$argument.0=,\\\" | grep -Po '(?<=inet\\\\\\\\\\s)\\\\\\\\\\d+(\\\\\\\\\\.\\\\\\\\\\d+){3}')\\\"\""

If my quote counting skills are good, you should also be able to use this which is much more readible:

method.insert = get_interface_ipv4_address, simple|private, \
"execute.capture=bash, -c, (cat, \"echo -n \$(ip -o -4 addr show \", (argument.0), \" | grep -Po '(?<=inet\\\\s)\\\\d+(\\\\.\\\\d+){3}')\""
