Reboot of DHCP-Server results in a mess of Client-IP-Addresses

Hi friends, in my network at home, driving some ubuntu-pc's one of them is dhcp-server running dhcp3-server. If i reboot this pc all the clients are going offline with a ahavi-ip-address (169.254...). what is going on during the short downtime of the dhcp-server, what is wrong on which side: client or server?

Peace Ice

Have a look at the lease time concepts of DHCP server.

Whenever I restarted the DHCP server, I never expect client to behave nicely.

Is it a good idea to set the lease time to a very high value, e.g. default-lease-time 600;max-lease-time 7200;What do you think?

I think the best deal would be to keep it a day. By default most DHCP servers are set to 24 hrs IIRC

Thanks, this is the best solution. i wonder why i got a lease-time of 600 in the default configuration...Now it is fixed, thx.Ice
