While looking through the handbook for info about CVSUP, I came across three "tutorials" on IP aliasing (one in the Handbook, one in the FAQ, and one in the "Tutorials"). All three basically suggested IP aliasing to the Ethernet card, using netmask 255.255.255.255 and adding route commands to route the aliased IP to the loopback device. However, for several years now I've been aliasing IP's to the loopback device directly, and using arp commands to distribute the aliased IP to routing daemons in the subnet if necessary. So, why is aliasing to the ethernet device preferable to aliasing to lo0? Or more accurately stated...what's the difference and why would one choose method A over method B? Thanks for the advice. -- John-David Childs (JC612) @denver.net/Internet-Coach System Administrator Enterprise Internet Solutions & Network Engineer 901 E 17th Ave, Denver 80218 "I used up all my sick days... so I'm calling in dead!"
