Hi there,
We have been trying to do IP aliasing on one of the machines. I went thro'
the mini-HOWTO/IP-alaiasing document and found these commands. Here
163.122.6.186 is the primary address (that our machine is already having)
and 163.122.6.253 is the one that I want to add to the machine.
The set of commands I follow are:-
/sbin/ifconfig lo 127.0.0.1
/sbin/ifconfig eth0 up
/sbin/ifconfig eth0 163.122.6.186
/sbin/ifconfig eth0:0 163.122.6.253
/sbin/route add -net 127.0.0.0
/sbin/route add -net 163.122.6.186 dev eth0
/sbin/route add -host 163.122.6.186 dev eth0
/sbin/route add -host 163.122.6.253 dev eth0:0
/sbin/route add default gw 163.122.6.200
at the execution of
/sbin/route add -net 127.0.0.0
/sbin/route add -net 163.122.6.186 dev eth0
an error occurs
SIOCADDRT: Invalid argument
SIOCADDRT: Invalid argument
The output of ifconfig -a after that is :-
lo Link encap:Local Loopback

The problem is like this:-
No machine is able to identify the machinine afterwards. So we have to
reboot the machine for the machine to get to its original IP address
163.122.6.186. Can you please suggest a better method of doing the IP
aliasing? Also please tell me if I can reset the error without rebooting.
Thanks in Advance,
Bye,
Vinay
