I am trying to assign multiple IP addresses to a single NIC for virtual
hosting on a FreeBSD 3.3 server.
Here is the current output of ifconfig:
bash-2.03# ifconfig ep0
ep0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 10.0.0.2 netmask 0xffffffe0 broadcast 10.0.0.1
ether 00:a0:27:06:ef:fe
The command I am trying to use is:
ifconfig ep0 alias 10.0.0.3 netmask 255.255.255.224 up
I have also tried entering the info into rc.conf, but after rebooting, the
only address that worked was the second one.
The command returns:
ifconfig: ioctl (SIOCAIFADDR): File exists
Which I believe means that the interface already has an address, and not a
problem.
After executing the command, ifconfig ep0 shows:
bash-2.03# ifconfig ep0
ep0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 10.0.0.2 netmask 0xffffffe0 broadcast 10.0.0.1
inet 10.0.0.3 netmask 0xffffffe0 broadcast 10.0.0.1
ether 00:a0:27:06:ef:fe
So I assume it has take the second address, however it will not reply to a
ping to the second address.
Any thoughts or suggestions would be appreciated.
