Hi all,
I've found this strange problem with my freshly installed OpenSuSE 11. Whenever I change something in Network Settings through yast, the working network configuration will simply disappear.

For example, I had eth0 up and running (DHCP). Then I fired up yast, Network Devices -> Network Settings -> Hostname/DNS -> edit hostname setting -> Finish. After I exist from yast, I found that eth0 is no longer shown in command ifconfig and the default route is also gone.

I then had to manually do a /etc/init.d/network restart in order to bring back the network. I've also tried to ssh to the same host and repeated the same steps and yast just froze when I hit the Finish button after I changed the hostname setting.

This is really annoying because there will be times when I need to remotely log in to the system to do some network setting changes. I know this is related to version 11 only because I've done the same thing with version 10.2 with no problem at all.

Has anyone come across this problem as well?

[EDIT]
the NIC card is a RealTek 8139
command ifconfig eth0 returns
Code:

          inet addr:192.168.1.101  Bcast:192.168.1.255  Mask:255.255.255.0

under working connection, the same command returns
