Network always restarts
Hi guys Smilie
I got a big problem.
Yesterday I changed the IP of a server. Then i restarted the network service, did a DNS entry and so on. Nameserver are the same as always.

After a few minutes after boot the network disconnects -> no ping, no ssh.
Approximately 30 seconds later it starts again. I can ping the server, connect on it with ssh, do all the stuff.
Minutes later, same problem, no ping possible.
If I'm on this server, I can ping all the others, but they cant ping the one where I changed the IP.

Dont know what to do Smilie

Best regards, Mairo

Sure you gave it a unique IP address?
