My configuration broken after recent update

[grzeg0rz]

Hello fellow OpenVPN users!

I am running my VPN gateway and everything was working fine until yesterday. Yesterday I updated my unprivileged podman container where I run openvpn server and it won't start anymore because OpenVPN tries to adjust MTU of tun device.

In the past I was setting up tun device myself (including MTU) and then within container I was replacing `ip` command with empty script which was always returning 0. But yesterday I noticed MTU is set through different method, this is my log:

Code: Select all

TUN/TAP device tun0 opened
net_iface_mtu_set: mtu 1500 for tun0
sitnl_send: rtnl: generic error (-1): Operation not permitted
Linux can't set mtu (1500) on tun0
Exiting due to fatal error

OpenVPN from before November works fine.

Can somebody point me at direction what can I do to preserve my root-less setup? I was looking at -up argument but it says script specified within this argument is executed after interface is up.

SITNL is Simple Interface To Net Link.

I guess it is not compatible with your unprivileged podman container ..

Next time, test before you upgrade.

The point of podman is to easily swap in and out different deployments so him switching back to his prior version is as easy as a couple of commands (assuming he backed up his pod) He IS testing.
