About a month ago I submitted a question about my failure to bring up network device aliases such as eth1:0, eth1:1, etc. There were no replies, but I've recently done some followup work on this and have some more information. The problem appears to be with dhclient... I rebuilt and installed dhcpcd snatched from rpmfind (this is what my box was using before Fedora 2). With dhcpcd installed, ifup will try dhclient to get dhcp settings, it will fail if the network device is an ethernet alias, and then ifup will try dhcpcd, which works with the alias. Any insights?
