[opensuse] DHCP Problem
My openSUSE 10.2 laptop has been on the corporate network since being upgraded from Vista in May (a week after I got it). Suddenly yesterday, I cannot connect to anything. I checked and found that my network - eth0 - is on but that I'm connected to a 'default' network of 169.254.x.x, which I'm told is a Microsoft network. My network admins (who work for me) are not able to help since none know Linux. We recently switched from an NT 4.0 Domain to a new AD setup. That switch was three weeks ago, so I can't imagine this issue is related. In googling, I found that there apparently is no GUI tool for configuring or renewing DHCP leases. I dropped down to the command line and have tried both 'service network restart' and 'dhclient -r eth0' In both cases, the network releases and then comes back. Ideas? This is too weird. -- kai ponte www.perfectreign.com -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

It's not a Microsoft network, it's a "zeroconf" network, which is a standard for setting up machines without any configuration at all. suse will fall back to that when it doesn't receive an address from the dhcp server

What is running on the server side? Is the AD thing also responsible for DHCP? If so, you should know that the Microsoft DHCP server is bad, even for them You can enable debugging output by setting DHCLIENT_DEBUG to "yes" in /etc/sysconfig/network/dhcp, which will log all the messages going between server and client. That will at least help you narrow down where the problem is
Ideas?
Since you seem to be the manager there, how about getting rid of microsoft and going to a linux only environment? :) Or hiring some people with more linux skills Anders -- Madness takes its toll -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Have you tried using Knetworkmanager ? -- Regards, Aniruddha Please adhere to the OpenSUSE_mailing_list_netiquette http://en.opensuse.org/OpenSUSE_mailing_list_netiquette -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

That address is the type that gets assigned when the DHCP address isn't assigned due to a timeout (for example). Have a look at /var/log/messages and grep for 'ifup-dhcp' to see if there are errors that could help.

Cool. I got it working, tho. I just typed dhclient eth0. That seemed to do the trick.
