Thumbs down Lost Connection?


Hello again,
Well I'm back, I have lost my connection to the web once more.
I have on my dual boot machine Win XP and Fedora Core 5, I was up and running on XP, then rebooted and booted up Fedora, only to find that i couldn't get on line? I have been running online in Fedora for about 6 days without a hitch. My Network say's I'm activated,But I can't get on line, My firefox is running, yet it can't find the servers? I tried to resart with the /etc/init.d/network restart command and all commands I know, Maybe someone else that had this problem can help? Thanks. fvs

There are many things worth checking. First is routing table. In the configuration tool check if you have a default gateway, or simply run /sbin/route and look if you have something like
Code:
default         192.168.1.1     0.0.0.0         UG    0      0        0 eth0
Then, look into the logs (/var/log/messages, you need to be root to read it) and see if there are messages about network connection, DNS server entries, network card notificatins and such things.

Do you have ANY network connection? Can you ping your router at all? Or any other computers?
If you can then the problem probably lies with the gateway, as said above.

If you CAN ping the router, then try:
route add default gw 192.168.1.1

Destination Gateway GenMask Flag

169.254.0.0 * 255.255.255.0 U 0 0 0 eth0

Couldn't copy and paste but that's what was retuned /sbin/route.

The 169.254.xxx.xxx are automatic priviate IP addresses when the client can not communicate with DHCP server. I assume that everything works when you boot in windows? What type of internet connection are you using? Do you have a router?

I'm on Win XP on the same machine and not a problem, I was using Fedora on the internet for about 6 days, The problem happened when I rebooted to Fedora after using XP, I have a netgear router.

Is your router configured for static or dynamic addresses? The entry means that Fedora tried to use DHCP, but it failed. It may be a good idea to look into system logs (/var/log/messages) and see if there are dhcp-related entries. Also, you can try to run it manually, so you'll see all the errors. Open a terminal, run su to become root and then type
/sbin/dhcp<press tab here>
The name should expand to something like /sbin/dhcpclient (I don't know what's the right name in Fedora). Press enter when it's expanded. It should connect to DHCP server and configure everything.

Mara, Thanks forgetting back to me, I'm totaly lost. I have been all over the net trying to get an answer that could solve the problem. The latest was to run my network static which I have done and I still can't get on. Here a a few places I've been;
/etc/resolv.conf
# generated by NetworkManager, do not edit!

search Cable.rcn.rcn


nameserver 207.172.3.8
nameserver 207.172.3.9
bash: /etc/resolv.conf: Permission denied
[root@localhost /]# /sbin/ifconfig

RX bytes:4405361 (4.2 MiB) TX bytes:4405361 (4.2 MiB)

[root@localhost /]# dmesg | grep eth0
eth0: forcedeth.c: subsystem: 01565:2501 bound to 0000:00:14.0
eth0: no IPv6 routers present
[root@localhost /]#
I can ping my idadress with out errors retuned also, I guess I tried every suggestion that came my way. Any Ideas?
