Help needed on toxvpn

Help needed on toxvpn …

I thought that my problems would be fixed with upgrading from 19.09 to 20.03. Unfortunately that’s not the case. Both boxes I want to connect are on the same LAN currently.

doing it interactively is working fine

toxvpn -i

from configuration.nix

 ## toxvpn
 services.toxvpn.enable = true;
 services.toxvpn.localip = "";

… and status of the service

root@nixos:/etc/nixos]# systemctl status toxvpn.service
● toxvpn.service - toxvpn daemon

one example for the manual start of the service:

[root@nixos:/etc/nixos]# systemctl start toxvpn
Job for toxvpn.service failed because a timeout was exceeded.
See "systemctl status toxvpn.service" and "journalctl -xe" for details.

[root@nixos:/etc/nixos]# echo $?

p.s. I hope that placing this request here is fine; if not please forgive my newbieness

Not familiar with this specific module. Do you know if it opens the necessary firewall ports?

I’m not sure and didn’t check; it’s most likely as you can see from the options


udp port for toxcore, port-forward to help with connectivity if you run many nodes behind one NAT
Default value: 		33445
Type: 		signed integer
Example value: 		Not given
Declared in: 		nixos/modules/services/networking/toxvpn.nix

I didn’t set it in configuration.nix.

It doesn’t seem to matter in “interactive” mode aka “toxvpn -i …”

setting the port explicitly in configuration.nix doesn’t help either

Somehow the problems have gone - thx to whomever did something in the background!

I’d like to mention that socat package is needed to control the socket for the service.

socat stdin /run/toxvpn/control

Perhaps it’s possible to setup a relationship between the packages.
