[Sorry for new post, I'm now on webmail, I can't see old ones] To Sudev...
I think I got it now right. 1. I made those changes for "next-server". 2. I did restart both dhcp3-servers. 3. I unplugged network cable. 4. I start thin client (172.23.24.25) 5. It did go online. Sudev, you made my day. Here are my syslog-files. I can see (and I hope that I now understand too) all those steps... I think this is very important line in both syslog files: Master: Sep 17 08:09:53 localhost dhcpd: pool 8130ab0 172.23.24/24 total 255 free 133 backup 122 lts -5 Slave: Sep 17 08:09:53 localhost dhcpd: pool 8130a58 172.23.24/24 total 255 free 133 backup 122 lts 5 Syslog - Master Sep 17 08:07:48 localhost dhcpd: peer ubuntu: disconnected Sep 17 08:07:48 localhost dhcpd: failover peer ubuntu: I move from normal to communications-interrupted Sep 17 08:07:50 localhost dhcpd: failover peer ubuntu: peer moves from normal to normal Sep 17 08:07:50 localhost dhcpd: failover peer ubuntu: I move from communications-interrupted to normal Sep 17 08:07:50 localhost dhcpd: pool 8130ab0 172.23.24/24 total 255 free 133 backup 122 lts -5 Sep 17 08:08:50 localhost dhcpd: Internet Systems Consortium DHCP Server V3.0.3 Sep 17 08:08:50 localhost dhcpd: Copyright 2004-2005 Internet Systems Consortium.
