'Unreachable Host' when pinging with RedHat 7.1. Help!
I am very new at Linux. My plea for help may sound a bit stupid for some of you old-timers. Well here it goes.
I was running Windows 2000 Advanced server on this machine and it connect very well with the other machines in the network. I uninstalled it and put RedHat Linux server in place. The machine has four NICs but I have only configured two with IP address and Netmask during the installation.
When I ping other hosts in the network I get 'unreachable host'. And When I ping this Linux box from other hosts I get 'Request Timeout'. I thought I'd test the TCP/IP stack on the machine so I pinged the loop address 127.0.0.1. I got a positive response. I thought may be we have physical connection problem. So I checked the NIC, the patch cable and the hub, but I saw nothing out of place. I am stuck. What could be wrong?
How do I reconfigure TCP/IP on RedHat Linux? I tried issueing the Linuxconf command but I got the reply that the file could not be found. Is there a known issue with RH 7.1 and network connectivity? Please help me.
