Im guessing, I could put the same thing in my rc.conf file, but with proper syntax: ifconfig_fxp0_alias0=inet 192.168.2.222 netmask 0xff The proper syntax for the netmask on the second and subsequent interface addresses from each distinct network block is to use the all-ones netmask: you can express that either as 255.255.255.255 or as 0x or as /32, whichever suit you best. This is a FAQ on this list but it still keeps tripping people up -- despite being clearly documented in ifconfig(8): alias Establish an additional network address for this interface. This is sometimes useful when changing network numbers, and one wishes to accept packets addressed to the old interface. If the address is on the same subnet as the first network address for this interface, a non-conflicting netmask must be given. Usually 0x is most appropriate. However you look at it, 0xff could never be a correct netmask.

Re: setting up network virtual hosts (ifconfig)
On a side note, if you set something up in rc.conf, how can you manually start it without having to reboot? Well that depends on what it is, but if you want to just go through everything you can do this: # shutdown now This will put you in single-user mode. Hit enter for the default shell, then just log out (Ctrl-D) and that will fire up init and run through the rc system again. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Re: setting up network virtual hosts (ifconfig)
What if you are doing this remotely? :) Any other way to get around that? Not unless you're connected to another machine and connected to the target box through a serial console. In this case you're probably better of making the change manually. What is it you want to reconfigure? ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
