Description Igor Nazarenko 2006-11-20 14:23:28 UTC

Proposing minor patch to vpnc-script, which fixes 2 problems:
1) When TUN is compiled as a module and the module is not loaded, vpnc-script doesn't attempt to load the module and directly proceeds to create /dev/net/tun manually, which doesn't work, since the device that gets created is not backed up ny the kernel. Workaround: modprobe tun before starting vpnc
2) When there's more than one default gateway with different metrics, vpnc-script correctly stores them both in a temporary file to be restored on disconnect. However, on disconnect it fails to properly restore either one of them. Workaround: manually re-add the gateways or /etc/init.d/net.eth0 restart.

Example route output which causes the bug:
# route

I'm going to try and attach a patch.
