Just been trying to work out why my network was not working after an
upgrade to Kubuntu 9.10.
I use my router to pass dns requests onto a server in the internet.
Resolv.conf looks pretty similar to that below - but without the first
comment line. This stopped working. When I tried dig, I would get
1.0.0.0 returned.
I removed the router as a dns (leaving the internet servers) and name
resolution was restored. I changed the static config on the Kubuntu box,
and the DHCP settings in the router before I thought to test it from
another machine - all of which use DHCP.
There did not seem to be any iptable entries to block the router/port,
and the routing tables seemed fine.
I am on a different machine now, and just sshed into the Kubuntu box,
and the router seems to have started resolving to it again. odd. I
haven't touched the router recently.
So no idea really. A joott. Unless ... your not on Telecom are you?
While I a on about networking - a question - I had not been using
network manager, but I have just enabled it. If I change some settings
in a connection, I cannot get them applied without rebooting. I tried
switching to another connection and switching back, restarting network
manager, restarting the network, but I do not get the new values.

Hi, following an upgrade to Karmic last night, I have no name resolution to the
interweb. LAN functions are fine, samba shares good, can ping other machines,
router, gateway, and can ping paradise/TCL name servers and can ping
www.google.com by name so have a degree of name resolution. I can see which of
my skype contacts are online. However all browsing in firefox returns
"connection has timed out" and thunderbird can't locate paradise pop or google
imap servers.
I still have the same resolv.conf file from before the upgrade:
#Generated by NetworkManager
nameserver 10.1.1.1
nameserver 203.97.78.43
nameserver 203.97.78.44
The network connection applet near the clock shows "Auto eth0" as active and
lists the same name servers as per resolv.conf, and the static ip address for
that machine. ifconfig also shows eth0 with that same ip address though I'm not
sure where it is getting that from, certainly not via /etc/network/interfaces
and the control module for network connections doesn't actually list any wired
connections. Changing the network management backend to wicd doesn't seem to
help (and doesn't show a network applet with status etc either).
I'd be very appreciative of any pointers on how to resolve this?
Cheers,
Roger
