404 not found on Ubuntu
 

I got fed up with Vista and put Ubuntu 9.10 onto my computer everything is working fine. I have learn a few things about how to run it sense then, but sometimes when I want to go to a website it would read:

404 on found

even though it is a website I was able to go onto before when I used the live CD version of Ubuntu. Also sometime it will redirect me to a different website example: I want to go to facebook and it direct me to some tech or business site. I need help trying to straightening this problem out.

ok
What browser are you using?
How are you typing the website into the address bar?
Does your nameserver setting have a third entry for basic search?

I think this is a problem with name-server configuration.
Your name-servers should be configured automatically.

try:
$nslookup www.google.com

see if any name-servers pop up.
If not contact your provider for name-server ips, so that you can configure them manually.

Or make sure that you have selected automatic configuration of name servers.
I have not used Ubuntu, so I am not sure of network configuration utility available to you.

I am using foxfire and I usually use google or bookmarks to look at different websites. I'm not sure if my name server setting has third party entry.

A name server has popped up, but sometimes when searching the web and going to a site it gives me the Error and sometimes it doesn't.

I tried Nslookup on "www.syfy.com/ghosthunters/" and it couldn't find it.
Then I tried going on the site again and it found it. Weird.

Is seem that some sites will work and some won't

your name servers should be in /etc/resolv.conf just type in the name server and thats it.

Should look simular to this
where the x are it should be a dns aka name server there.

try nslookup on www.syfy.com only because thats the name of the server.
You will probably find the dns used to resolve the address. Check if any of your friends use the same dns as you are, try using dns they are using.
Also make sure that if you supposed to use a proxy server, then you will have to make necessary changes in proxy server settings

Well I set nslookup into my proxy settings under preferences in Firefox I'll see how that works.

Well I gave up on Ubuntu 9.10 and down graded to 8.04. I was having too many problems with it. I'll see how it works.
