Public bug reported:
Binary package hint: network-manager
My normal connection is wireless, with a static ip and manually set DNS
info. When I temporarily connect my computer to a wired network,
network-manager automatically configures using DHCP. In doing so, it
overwrites the manual DNS info in /etc/resolv.conf with the DNS info
from DHCP completely. When the wired line is disconnected, wireless
doesn't work because the manually set DNS info is not restored.
I assume the culprit is network-manager in this case because the
overwritten /etc/resolv.conf appears as follows (some whitespace
removed):
# generated by NetworkManager, do not edit!
nameserver 192.168.2.1
This happens on Ubuntu 7.10 testing, Tribe 3, up-to-date as of 2007-08-05.
network-manger version is 0.6.5-0ubuntu7. The install is one day old and
relatively clean.
This bug is probably related to [#126592 resolv.conf overwritten on dhcp
renew when using NetworkManager vpn plugins]
