Internet, e-mail not working... except on LJr.

[Lixus Looser]

I am having serious internet issues. For some reason, I could get to linuxjunior.org, follow links, and even make this post, but I can't surf the web (mostly), can't use my RedHat Up2Date agent, check e-mail or log onto IM. My DSL is connected and running property in Windows, and the surfing LJR doesn't seem to be a problem, but I can't otherwise seem to access the internet... HELP!??? Running Fedra Core 3. Have been updating. Haven't had any trouble until recently....

Thanks. :

Run a tail -f on /var/log/messages, bounce your network interface and
note anything that looks "odd". Also, trying pinging your ISPs pop server, what do you get?

hello,
are the dns servers listed in /etc/resolve.conf ?

What was last thing changed or installed on your Linux OS?

This is it:

; generated by /sbin/dhclient-script
search domain.actdsltmp
nameserver 192.168.0.1
nameserver 205.171.3.65

Looks like, for some reason, you are querying first a host on your local lan. (192.168.0.1)

Try inverting the entries for nameservers:

search domain.actdsltmp
nameserver 205.171.3.65
nameserver  192.168.0.1

I think I updated Cups and SELinux. Other than that not too sure...I run the Up2Date agent when it tells me to. I haven't installed anything since I installed the OS as far as I can remember... That was just two weeks ago or so...

I don't understand this. I'm relatively new to Linux. Can you tell me HOW to run a tail -f on /var/log/messages...

I should also say that everything was working perfectly fine until about three days ago and I don't know what changes I have made that would screw it up...

log in as root, open up a shell, click on something that looks like this if you're using kde
and then type in:
tail -f /var/log/messages

Are you able to ping google.com?
