Good Day all my Linux Guru friends

I am relatively new to Linux. I have installed Redhat Linux Fedora Core 4, as a server, linked on a network, with Windows machines as clients. Now that was not really because I wanted to, but because I had to, due to the fact that I need to do it as one final subject for my University studies. Not that that fact is not allowing me to like the O.S. However, now for the problem.

I have set up the O.S., working wonderfully, earlier. I had no problem watsoever. Then I didn't use the server for a while and whalla!!! no ping to my ADSL router, only pinging the Network Card, i.e. 127.0.0.1. I have changed network cables, in case the cable might have been the problem, but the problem still persists.

The only change that I can think of is, the fact that I have enabled port forwarding on the ADSL Router. How can I go about getting at least my server communicating with my ADSL Router again. without having to reset my ADSL Router to factory settings again? Previously I have changed from a static IP address, to automatically obtaining an IP address through DHCP and everything worked fine. Now neither works. Any suggestions please?

Greetings,
Yours faithfully

depending on the desktop you are using there are different tools available to set the default gateway=ip of your router. Probably this is using a different netmask...but you may know the ip of the router...
You can edit /etc/resolv.conf manually to enter a line like
nameserver 192.168.2.111
(at best with the right address;-])

hope this helps, good luck, j.

Did you try pinging to/from other machines on your internal network?

Is eth0 properly listed when you run ifconfig from shell?

If its on DHCP, try running:

dhclient -r

Or:

service network restart

Or

ifconfig eth0 down
ifconfig eth0 up

Hope this helps.

Hi J-Ray,
Thanks, I'll try that. The desktop I'm running is KDE. When I run ifconfig, it only lists the loopback address, for eth0. Oh yes, I have also exchanged Monitors in the mean time. The fact that I have turned IP forwarding "on" on the router should those two changes make a difference?

Hi Kenoshi,
No, I can't ping the server from the other machines. They respectively can ping the router, yes.

Firstly, it's just called Fedora Core. Secondly, Fedora Core 4 is no longer supported and you'd be better off installing the newest version.
