Title:
Network manager fails to set domain server in some circumstances
Status in network-manager package in Ubuntu:
New
Bug description:
Occasionally, after a resume from an update, network manager starts
behaving strangely, not setting the DomainServer for the network.
This happens when resuming the laptop to a location where:
- an additional ethernet card (which is the one to use) is attached via USB
- configuring that ethernet card NM is set up to clone a given mac address
and get addresses only from dhcp, while the dns server is set manually in the
network manager configuration
- there are also free wifi signals to which NM tends to connect
In this setup, NM fails to set the dns name in dnsmasq
The issue gets worked around by either
1) Using qdbus to call the dnsmasq dbus method to set the domain
server. In this case the solution is temporary. Namely when NM is
asked to disconnect from the net and then to reconnect, the issue
comes again; or
2) Killing dnsmasq. In this case, dnsmasq ia automatically restarted
and everything starts working fine; or
3) Restarting NM itself.
