You've put wrong netmask. If there is IP on the same network on the sane
NIC, then the netmask should be 255.255.255.255.
So, try this:
ifconfig xl0 inet 192.168.10.2 netmask 255.255.255.255 alias

Subject: Problems with IP aliasing
HI
I'm trying to create IP aliases of the ip 192.168.0.2
so i create the alias 192.168.10.1 with no problems
this way:
ifconfig xl0 inet 192.168.10.1 netmask 255.255.255.0
alias
[root@gator:/usr]# ifconfig
xl0:
flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu
1500
inet 192.168.0.2 netmask 0xffffff00 broadcast
192.168.0.255
inet 192.168.10.1 netmask 0xffffff00 broadcast
192.168.10.255
ether 00:10:5a:07:da:30
media: Ethernet autoselect (100baseTX
<full-duplex>)
status: active
[root@gator:/usr/ports/mail/squirrelmail]# ping
192.168.10.1
PING 192.168.10.1 (192.168.10.1): 56 data bytes
64 bytes from 192.168.10.1: icmp_seq=0 ttl=64
time=0.080 ms
64 bytes from 192.168.10.1: icmp_seq=1 ttl=64
time=0.044 ms
the alias is there and working
then i tried:
[root@gator:~]# ifconfig xl0 inet 192.168.10.2 netmask
255.255.255.0 alias
ifconfig: ioctl (SIOCAIFADDR): File exists
[root@gator:~]#
any ideas why???
thank
