I have almost fresh Ubuntu desktop box. OS was installed two weeks ago and updated from karmic repositories. Last week I had no problems with DNS. But this week something had changed. I'm not sure what and when, and not sure whether I changed any configs.
So now I have some really weird situation. According to logs name resolving should work normally.
/etc/hosts
127.0.0.1 localhost test
127.0.1.1 desktop
/etc/host.conf
order hosts,bind
multi on
/etc/resolv.conf
# Generated by NetworkManager
search search servers obtained via DHCP
nameserver 192.168.0.3
/etc/nsswitch.conf
passwd: compat
group: compat
shadow: compat
hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4
networks: files
protocols: db files
services: db files
ethers: db files
rpc: db files
netgroup: nis
But if fact it is not.
user@test ~>ping test
PING localhost (127.0.0.1) 56(84) bytes of data.
[skip]
Pinging is ok.
user@test ~>host test
test.mydomain.com has address xx.xxx.161.201
I suspect that NetworkManager might cause this misbehavior, but don't know where to start to check it. Any thoughts, suggestions?
