How to ping using secondary ip address as source address.

[Guest_imported]

My nic has two ip address. May I know how to ping using secondary IP address as source address ?

umm, you can ping with an interface address ...

ping -i <ip address> <host to ping>

Tried already, but still didn't work. Use the -i option and then snoop the packet, found out Solaris still use primary ip address. I think the -i option is for multicast.

not necessarily ... it probably just thinks that it can use the first as it's primary interface ...

if you had netmasks set up, so that each ip was on a different subnet then it would probably work ...

i have 3 cards in my machine and i can ping -i <any interface> and get the host i want, but then again it's because of the routing. it uses the primary ip to route to the destination machine ... i guess you could look at the ifconfig -a ...

try using a different host name...create a file called hostname.<interface name> and enter the new hostname in there

example: /etc/hostname.hme0 10.x.x.x
/etc/hostname.hme:1 10.x.x.x
