[Bug 274178] Re: dhcp3-client can't set IP address due to insufficient rights

[Jeroen Roovers]

As first noted in https://bugs.launchpad.net/ubuntu/+source/network-
manager/+bug/329105/comments/7

network-manager successfully starts dhclient, but dhclient never returns
and doesn't set up the network interface:

/var/log/daemon.log after selecting a connection in nm-applet:

ra0 shows some traffic but never goes up. I see the same consistent
misbehaviour with eth0. Both interfaces work fine when started without
using network-manager or dhclient.

The attached strace of dhclient3 shows that dhclient is not allowed to
run /sbin/dhclient-script.
