Fedora behind Fedora problem

Djjules · #1 17th September 2005, 06:05 PM

Hi all!

I have a server with static IP from my ISP.

My server works as a dhcp server running Fedora Core 3. There are 8 Windows XP machines behind that server working just fine with internet connections etc.

Then I installed Fedora 4 to my laptop and connected it to the network the same way those Windows machines were connected.

Now I get IP just fine from my server as the other computers do, but when I try to connect to the internet, it won't connect. When I try to ping my server it gives an error "network is unreachable"

.

I think I've tried everything possible, but still the problem remains.

Is there a difference if I change the localdomain.localhost on my laptop to something? In case there is, should the localhost be the exacly the same as my server's localhost?

It seems that the connection to the server works just fine beacuse the dhcp gives me the right IP, but something is missing, 'cause I can't ping other machines on my network.

To solve this problem is VERY important to me, so PLEASE help me with this...

I tried to search any similar problems, but the answers I got couldn't help me.

Thnx

Can you ping an ip address, or did you meant that with pinging your server? I sometimes have a static ip, but when I want to use that I have to delete the static ip and submask, they have to be empty, even if I don't use them.

I can ping only my laptop with my laptop, but I cannot ping neither the server's static ip to internet nor my server's ip for local network (the dhcp IP). And of course I cannot ping any of the computers in the network... The only thing I can ping is my laptop and its aliases.

It seems that some simple config file is either missing or having the wrong settings, but this is only guessing....

One thing left to try is to ping my laptop from one of the Windows machines.

Sounds like something to do with routing. What does
/bin/netstat -r
tell you?

Umm /bin/netstat -r tells me following:

Kernel IP routing table
Destination Gateway Genmask Flags MSS WINDOW irtt Iface
10.0.0.48 * 255.255.255.252 U 0 0 0 eth0
169.254.0.0 * 255.255.0.0 U 0 0 0 eth0

So what I seeing here is that 10.0.0.48 is wrong destination; should it be something like 10.0.0.1 (my server's IP)

But the mask is correct.

Me noob
