Code:

root@auth:~# ifconfig

          inet addr:10.1.1.150  Bcast:10.255.255.255  Mask:255.0.0.0

          inet addr:127.0.0.1  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:16436  Metric:1

ETH1 and ETH2 are conected to two other hub's for 2 differents subnets.However the machines from 192.168.1.x and 172.168.10.x can't ping the linx box....But if i diconect the cable from ETH0 and ETH1 i can ping ETH2 or if i disconect ETH0 and ETH2 i can ping ETH1....

Can any one help?Please....

What Linux distro are you using? Can you post the output of netstat -rn?

I already figure it out thanx...

As a heads up for everyone else what was wrong?

Even setting the NIC Ip address of clients in the same network it wouldnt ping.. but after set the gateway as the server ip address.....
it worked fine....
Dont ask me why....
