XFCE networking failed after an update

English Network/Internet
1

Hi I have openSUSE 12.3 with an XFCE desktop. The networking has been OK until last night when I allowed an on line update to complete. Then I lost name resolution in all outside functions e.g. I can’t ping websites, or download torrent files or use web browsers. But I can see and access samba networked computers. And I can ping local computers by IP.

Yast shows the router gateway in “network settings” and the command “route” shows the following:

quantaos321:/home/john # route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         192.168.1.1     0.0.0.0         UG    0      0        0 eth1
loopback        *               255.0.0.0       U     0      0        0 lo
link-local      *               255.255.0.0     U     0      0        0 eth1
192.168.1.0     *               255.255.255.0   U     0      0        0 eth1

and it takes like sixty seconds for the command to execute.

The name servers are listed correctly in resolv.conf:

..........etc etc etc..........
#
### Please remove (at least) this line when you modify the file!
nameserver 8.8.8.8
nameserver 8.8.4.4
john@quantaos321:~>

It doesn’t matter if the firewall is on or off.

If I try to look in the router from the web browser, using the router IP, it doesn’t see the router.

Any ideas?

Can you ping your own address successfully? The gateway? I wondered if you might have an IP address conflict with another device on the LAN? I notice you are using eth1. Does this laptop have another network interface available to try?

Can you ping 8.8.8.8?

If you don’t see the router by IP, the problem is not DNS, it is
connectivity to your router. First step, reboot the router.

Output of ifconfig?

As an aside, the reason that ‘route’ took so long to complete is that it was
looking up the name for all of the IP addresses in the routing table. Use ‘route
-n’. To understand the difference use ‘man route’.

Thanks all…
