[Solved] Openconnect VPN stopped working

Hello!

I haven't tried connecting via VPN for a week or two, and now it doesn't work anymore.

I use nm-applet to connect. I haven't been able to get it working by calling openconnect directly, either.

I tried downgrading the networkmanager, networkmanager-openconnect and openconnect packages, but it didn't help.

If I check the journal (journalctl -b -e -p err) after an attempt to connect, I always see this:

apr 17 17:41:38 arch NetworkManager[346]: <error> [1397749298.218453] [nm-vpn-connection.c:1374] 
apr 17 17:41:38 arch systemd-coredump[18746]: Process 18735 (obtain_cookie) dumped core.

The core dump is being caused by /usr/lib/networkmanager/nm-openconnect-auth-dialog.

I have no idea what else to try. I can't find anyone complaining about openconnect core-dumping.

Thanks!

Re: [Solved] Openconnect VPN stopped working

Solved!

I checked the logs again, this time journalctl -b -e. This finally showed me *all* the messages. (I still haven't gotten the hang of systemd yet. )

Anyway, this showed up (among hundreds of GLib-CRITICALs complaining about some IDs or some such):

apr 17 22:04:43 arch NetworkManager[335]: <info> Starting VPN service 'openconnect'...
apr 17 22:04:43 arch NetworkManager[335]: <info> VPN service 'openconnect' started (org.freedesktop.NetworkManager.openconnect), PID 17565

Segfault! libgnutls.so!

I downgraded gnutls to 2.3.13-1 and it works again.

Edit: I also noticed systemd-journald ramps up CPU and memory usage after the segfault. But I don't think a core dump is actually generated. At least I can't find it with systemd-coredumpctl. And the logs aren't very verbose at all. What is it doing?
