I'm connected to a home network.
suddenly I can't serf from my fedora station. I checked with a live cd and on XP and everything is ok.
how can I find out what's wrong and fix it?
thanks

Check that you can ping the IP address of your router/gateway.

Check your /etc/resolv.conf and make sure the nameserver entry is correct and that you can ping that IP address also if it is different from router/gateway IP adress. If you have a search line try saving copy of resolv.conf and take out the search line.

If you still cant serf after that then post output of
ifconfig
route -n

ok, I can ping 216.239.41.99 but not surf www.google.com (the hostname), I can ping my router as well. I'm told that it is going to the direction of a DNS problem (I use DHCP).

ifconfig is:
eth0 Link encap:Ethernet HWaddr 00:20:ED:56:B7:15
inet addr:192.168.0.4 Bcast:192.168.0.30 Mask:255.255.255.0

route -rn gives:

whice way from here?
thanks

That's good, basic networking is fine.

see if you can ping www.google.com by name.

post your /etc/resolv.conf

beyer42 · 12-19-2003, 03:21 AM

Also edit /etc/sysconfig/network-scripts/ifcfg-etho

and change BROADCAST to 192.168.0.255

then do
ifdown eth0
ifup eth0

ok, beyer42 - thanks a bundle.
the nameservers in resolv.conf were wrong. I fixed them and now everything is working again.
I probably should do some networking reading..
thanks again.
