Issue with ethernet interface
hello,
I have a Linux server with two interfaces eth0 and eth1. I configured two IP addresses from two different networks on 2 interfaces, and I connected both interfaces on two different switches.
the IP address of eth0 is responding without problem to ping from equipment of its home network, unfortunately this is not the case for the IP address of eth1. a moment I thought the problem was on the switch, but when I try to connect another device on the same switch port, this device can communicate with others on the same network. LEDs are lit, but impoosible to ping the IP address of eth1.
suddenly I thought to myself that maybe the problem come from the IP configuration on the interface eth1, or within the system that I do not control too.
well, I have to ask you for help to solve this problem.

thank you in advance for any contribution

Can you post the output of iproute2 for both NICs? (or ifconfig)

Well, there is no eth1. All the other NICs have traffic shown for RX and TX. If you are talking about eth2, have you checked the routing settings or do you ping from the same network?

Old 02-18-2014
yes it's eth2, and I ping from the same network (10.6.0.0)
# 6  
Old 02-18-2014
What is the IP of the system you are pinging the server with?

Very basic but missing information: have you correctly set their hostnames in /etc/hosts , that must be different if you dont want serious issues and each interface should have their correct GW set also... or were you just testing using IP which would not change the fact that each Network should have its correct default gateway...
