I couldn't find a response to this on the list, so here goes. They way I learned how to add aliases was a totall seperate file that seems to work much easier for large numbers of aliases. In /etc/rc.conf, just setup the first interface, no aliases. Then, create a file /etc/aliases (or whatever). It should be chmod'ed 700 and chowned to root. The file looks something like this: ifconfig de0 inet aliases.ip physical.ip alias netmask 0xffffff00 ifconfig de0 inet aliases.ip physical.ip alias netmask 0xffffffff ifconfig de0 inet aliases.ip physical.ip alias netmask 0xffffffff The aliases.ip is just the new ip, and the physical ip is the ip of the box. Notice the netmask, 255.255.255.255 (0xffffffff). This is because you are creating a little 1 host network that the computer thinks is also your real ip. The de0 is just your network card's device. After creating the file with all the ips you need, place a line in /etc/rc.local running this file at startup. I.E.: echo -n ` aliases` /etc/aliases That should work for an unlimited number of ips (theres probably some huge limit, but oh well). I've seen over 3 C classes running off 1 box without a problem. -Jake Sally sells C Shells by the seashore.
