Hi,

I am novice to linux setup. Any help related to this issue will be appreciated.

I have static route for eth1:

[root@perseus anvltest]# ifconfig eth1
eth1 Link encap:Ethernet HWaddr 00:0C:29:51:37:B5
inet addr:13.3.3.2 Bcast:13.3.3.255 Mask:255.255.255.0
inet6 addr: fe80::20c:29ff:fe51:37b5/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:4 errors:0 dropped:0 overruns:0 frame:0
TX packets:14 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:240 (240.0 b) TX bytes:868 (868.0 b)


eth1 (13.3.3.2) is connected to router port 2/0 (13.3.3.1).
I am trying to ping from eth1 to router or vice versa. None of them is not working. Don't know what is problem.

[root@perseus anvltest]# ping 13.3.3.1
PING 13.3.3.1 (13.3.3.1) 56(84) bytes of data.

Run 'ethtool eth1', what is returned?

How did you set up the interface? With commands? What commands? Or editing a file? Which file?

What distro is this?

Thanx for reply,

[root@perseus anvltest]# ethtool eth1

** I have used "ifconfig eth1 13.3.3.2 netmask 255.255.255.0 up" command to configure eth1 ip address.

[root@perseus network-scripts]# pwd
/etc/sysconfig/network-scripts
[root@perseus network-scripts]# cat ifcfg-eth1

[root@perseus ~]# cat /etc/redhat-release

It should work. Try removing the GATEWAY=10.11.197.62 line and restarting networking.

How do you know the router is working? Try a different cable.

I restared network by removing gateway. Still same result. My router is working, i am sure about that and I changed cable too(crossover & ethernet cable)
