Something gone wrong with VPN
I have problems connecting to VPN from my arch box. I can connect through Windoze to same VPN and the account and setting are just fine.
Everything was well during last few days, I was connecting on everyday basis and the only problem was the fact I can't connect through networkmanager applet.
So I had to connect with
$ sudo openvpn --config foo.ovpn
and had to write little script which automated the process of writing VPN's DNS servers to resolv.conf because it always gets overwritten by networkmanager.
Now it just stopped working suddenly, I did not change anything and that is even more mysterious. After I issue the openvpn command, I get the usual "initialization
sequence completed" and when I check resolv.conf theret are the correct servers, but there is no connection and I cannot ping any internet server.
Before connecting to VPN ("normal" Internet)

Re: Something gone wrong with VPN
This is getting really annoying. Sometimes it connects and I can normally surf (now in 10% cases), sometimes it does but I cannot surf. "Resolving host" and cannot ping anything.
The procedure I follow is the same as always:
$ sudo modprobe tun
$ cd /etc/openvpn
$ sudo openvpn --config foo.vpn( now after I got "Connection Sequence Initialized": )
$ sudo vi /etc/resolv.conf( now I modify resolv.conf and add my virtual private network's DNS nameservers after which sometimes (now rarely) I can surf and sometimes (more often) I can not )
Simply isn't logic. What am I missing?
<EDIT>
This obviously was a bug. After I reinstalled my system from the scratch and configured for i686 instead of buggy 64-bit, everything works great.
