One thought, There are numerous dhcp clients out there for linux. Some are tuned for different scenarios. I ran into this problem when dealing with windows based dhcp servers a few years ago, and simply changed which dhcp client I was using. This seemed to rectify the situation. You might try delving into the dhclient config file to make sure there aren't any compatibility options checked/unchecked that ought or ought not to be there.

After restarting dhcp services, I find that none of my Linux machines could recover their IPs without restarting their network service even after the lease time has elapsed. I use "static" dhcp so a machine's IP/DNS is really fixed. The dhcp service has been running now for a week and I'm still running into the stand-alone Linux box that has not recovered its IP. The box is running. dhclient is running. ifconfig shows that the eth0 device is initialized; it just lacks its IP. All the Windows boxes survived the dhcp outage. It appears that dhclient does not work properly on Linux. I assumed that dhclient would relinquish the IP after the lease time, then keep trying to request a renewal. But, apparently, it doesn't. It appears to have given up Ideas, anyone? Ken
