I am trying to connect to my VPN through my Asus RT-AC68U Router, and it shows in the error log:

Code: Select all

Jan  2 04:01:14 openvpn[7678]: OpenVPN 2.3.2 arm-unknown-linux-gnu [SSL (OpenSSL)] [LZO] [EPOLL] [eurephia] [MH] [IPv6] built on Oct 27 2015
Jan  2 04:01:14 openvpn[7678]: Socket Buffers: R=[122880->131072] S=[122880->131072]
Jan  2 04:01:14 openvpn[7678]: failed to find GID for group nogroup: Invalid argument (errno=22)
Jan  2 04:01:14 openvpn[7678]: Exiting due to fatal error
Jan  2 04:06:08 rc_service: httpd 21542:notify_rc restart_vpncall
But Every other client works totally fine, Phone, windows pc's, etc.
I'm a noob at this so I was wondering how to solve this issue!

Do you have a group called nogroup ?

I do, as well as a group called "openvpn"

I have the exact same problem, only on an asus rt-ac87u router

If i list the groups on my host using the "groups" command it only says "root"

If i try to add the group, using the "groupadd nogroup" command, i am informed that the group allready exists.

Exactly, with the ASUSMerlin firmware it works fine but the speeds are WAY too slow to be bearable. I'd just rather stick with stock firmware on my router for now but I don't have enough knowledge to figure out what to do to fix that issue.

I figured out how to make it work with the stock firmware on RT-AC87u. Just make sure your ovpn file says "nobody" for group instead of "nogroup"
Should also work for the other ASUS routers.

Some clarification:
in the ovpn file, find and change these lines

from:

Code: Select all

# Downgrade privileges after initialization (non-Windows only)
user nobody
group nogroup
to:

Code: Select all

# Downgrade privileges after initialization (non-Windows only)
user nobody
group nobody

It worked for me. I changed nogroup for nobody on both the server and ovpn file

thx
