[Bug 691723] [NEW] OpenVPN Client Ignores DNS

[Cerin]

Public bug reported:

Binary package hint: openvpn

The openvpn client does not correctly update /etc/resolv.conf with DNS
data provided by the openvpn server.

The log shows the client is receiving control messages containing valid
DNS.

e.g. Fri Dec 17 16:17:35 2010 PUSH: Received control message:
'PUSH_REPLY,route 10.123.10.0 255.255.255.0,dhcp-option DNS 10.123.10.12
,dhcp-option DOMAIN mydomain.com,route 10.88.0.1,topology net30,ping 10
,ping-restart 120,ifconfig 10.88.0.38 10.88.0.37'

However, I'm unable to resolve any VPN-specific domains until I manually
add the DNS and DOMAIN values to my /etc/resolv.conf. Even then, the
mechanism that normally maintains this file appears to periodically
revert the file to the original values.

I've tried installing both Network-Manager xor Wicd network managers, as
well as resolvconf, but I'm still required to manually edit
/etc/resolv.conf in order to use my VPN.

Openvpn, or some proxy program for openvpn, should update
/etc/resolv.conf with the DNS and DOMAIN received through control
messages. e.g.

domain mydomain.com
search mydomain.com
nameserver 10.123.10.12
