Hi

What is the status of that port ? Is it up ?

use ifconfig eth0, you will see something like
eth0 Link encap:Ethernet HWaddr 00:01:80:04:61:66
inet addr:192.168.157.11 Bcast:192.168.157.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:1735772 errors:0 dropped:0 overruns:0 frame:0
TX packets:867253 errors:0 dropped:0 overruns:0 carrier:0

RX bytes:159293174 (151.9 Mb) TX bytes:702011321 (669.4 Mb)
Interrupt:11 Base address:0x1000

Noticed that UP BROADCAST line ?

and I have to ask this, have you checked the cable ? Is the light up on your NIC and switch ?
Can other host ping this one ?

Can you get outpout of the following two commands
ifconfig eth0
netstat -rn

thanks

you have to configure the network, try configuring it using Network Device control application under System tools menu from the GUI.

Any other server is:

Any other server on the same network

Or

Any other server on other network

I mean, the gateway is needed for connect to other networks.

What is the ouput of ifconfig ?

Can able to ping to localhost and myhost hostname and 10.1.244.1 ip-address?

It is because of your routing setting. Check route or netsat -rn output. If you don't find default gateway for routing then you've add it to resolve other hosts in the network.

hth.

Hi Basheer,
try: ifconfig ethx up
Can you ping your default gateway?

Thanks for all

This is what solved the problem

I took eth0 thinking this is on the motherboard, then it turned out eth1 - which is on the mother board

Network Devic - uncheck activate on boot for eth0 and eth2
check for eth1 and provide network info

ifdown eth0
ifdown eth1
ifdown eth2

ifup eth1
ethtool eth1
and look for Link Detected : Yes

then able to talk to the network.
