Hello, I'am playing with samba and cups. Now i have 2 print servers load balanced with samba, cups, heartbeat. I use 2 computers with 2 ethernet cards by machine. network network | | | | | X | eth0 | eth0 Node 1--------Crossover link--------Node 2 eth1 eth1 when all is ok, on node 2 public interface eth0 is down and up on node 1. if node 1 fail, hearbeat shut down public interface on node 1 and activate eth0 on node2. Virtual IP address moves on node 2. Samba is listening only on private interfaces (eth1) on node 1 & 2. We are connected with network and DC (win2k) with a nated connection. The two samba servers are identical: we copy all tbd files from node1 to node 2. All seems to work for now... Wait and see A+ Pierre Thank's to samba dvl for their great job :-)
