>traceroute: Warning: Multiple interfaces found;<<

You need to add route to 172.16.12.133 in your server becoz you have "Multiple interfaces "

how to add route
please give the command

Re: trace route

Johnson Punniyalingam — Tue, 23 Dec 2008 10:54:03 GMT

route add net 172.16.12.133 netmask 255.255.255.255 172.16.2.65 1

(pls check the netmask) this will add a static route. than try

Therea are two way to do what you want.

1.)traceroute -s 172.16.2.83 172.16.12.133

or

2.)traceroute -i lan4 172.16.12.133

In #1 above you give it the IP address you want to use as the source for the trace and in the #2 you are giving it the lan card you want to use.

Good luck and Mary Christmas
