I am not sure if I have this right but you have two addresses set up on a single NIC; eth0 and the alias ip is eth0:1. I was googling this and the only thing that I found was a warning; "This alias IP address will cause some problems if you do not provide static IP address to DRBL client via its MAC address. In this example, the DRBL server will lease IP address to any machine connected to eth0 if no MAC address is set in the DHCP service." I don't know if this helps. -- You received this message because you are subscribed to the Google Groups "NLUG" group.
