(Please reply to me directly, as I'm not subscribed to this list. Thanks.)

I have two machines:

reseller3# uname -a
FreeBSD reseller3.safepages.com 3.1-RELEASE FreeBSD 3.1-RELEASE #0: Mon
Feb 15 11:08:08 GMT 1999 jkh@usw3.freebsd.org:/usr/src/sys/compile/GENERIC
i386

reseller2# uname -a
FreeBSD reseller2.safepages.com 3.1-RELEASE FreeBSD 3.1-RELEASE #0: Mon
Feb 15 11:08:08 GMT 1999 jkh@usw3.freebsd.org:/usr/src/sys/compile/GENERIC
i386

I have no problems bringing up IP aliases on reseller2, using this as my
command:

ifconfig ep0 inet <ip> netmask 255.255.255.248 alias

However, whenever I try to do this on reseller3, I get:

reseller3# ifconfig ep0 inet 208.244.234.134 netmask 255.255.255.248 alias
ifconfig: ioctl (SIOCAIFADDR): File exists

It then shows up in the ifconfig -a:
ep0: flags=8847<UP,BROADCAST,DEBUG,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 208.244.234.132 netmask 0xfffffff8 broadcast 208.244.234.135
        inet 208.244.234.134 netmask 0xfffffff8 broadcast 208.244.234.135
        ether 00:20:af:1b:0c:97 

However, the ip address is unpingable or unreachable in any way. This is
not the case with reseller2, which is running the same release (as shown
above) and is using the same type of ethernet card.

Does anybody have any suggestions as to how I can correct or debug this?

Andy
