Public bug reported:
On ubuntu 12.04 beta, to connect to a VPN by network-manager-gnome takes
long.
It takes about 10s to connect with Ubuntu 12.04 and less than 1s with Ubuntu
11.10 or with an Android device .
(Btw: on Ubuntu releases 11.04 and before it also took about 6s)
This is independent of the VPN protocol used: it happens with
network-manager-vpnc as well as with network-manager-openconnect.
Expecting the rooting table and /etc/resolv.conf during the connection
phase showed that setup of the tun0 interface including the correspondig
interface route as well as the DNS config in /etc/resolv.conf is done
quickly (below 1s).
But it takes an extra 10s until the default route is replaced!
In following syslog the connection phase stalls after setting up the
nameserver between 16:54:39 and 16:54:48 :
