Title: 2 pc's connected to the lan are not pinging from each other
Post by: sekhar_vrc on August 02, 2004, 02:05:39 AM

Hello

I am a newcomer in linux but have some windows and uniix knowledge.

I have 2 pc's

          pc-1 with ip address 192.168.0.1    255.255.255.0
          pc-2 with ip address 192.168.0.2    255.255.255.0

I am not able to ping pc2 from pc1 and vice versa.

I am using R.H 9.0 in pc-1 and RHEL 3.0 work station in pc-2 .

Is ping is disabled by default in linux.

My cable to the lan is intact as i am able to ping the same if i use  windows 98 o/s
in both the pc's.


Pl help me

strange.. by default it doesnot block ping ...

btw .. to make sure if there is a firewall.. run

Code: [Select]

iptables --flush -t nat
on both PC and then try to ping each other then tell us.

I think firstly u have to make sure if ur network card is up or not....

Login as root. Type the "ifconfig" command.

U should see the eth0 or something other numbers beginning with eth.

If u dont then, ur network card is not up.

you can assign the new IP address.

go to the linux terminal (command Prompt)

#netconfig
Assign the new IP address with netmask.


It is not work ...then check ur network cable whether u are using straight cable or cross cable.
if u hv 2 standalone Pc (without hub/switch) ,use cross cable.

hope it will help you. bye
