mozilla cant find web sites
 

When I connect to the net with my modem, mozilla doesnt have any problems with any web pages, but when I go to the local telecentre when I'm in town, about half of the web pages wont load with mozilla saying that it cant find that address. I have put the dns servers in my /etc/resolve.conf and I still get the same problem. When I go into network device control and look at my eth0 connection, it shows the right dns server addresses. So does anyone have any ideas as to what else it could be. I'm also having trouble getting up2date to actually update and also cant get yum to install any thing (which I think are seperate problems, but if anyone has any ideas) When I run yum I get
"[root@localhost root]# yum check-update

Ive tried updating the base and updates released urls in my yum.conf file but it doesn't seem to have done anything. When I run up2date it hangs on fetching the headers. Thanks in advance.

Find a number of servers you can't access and try
dig servername
one after another. What do you get as an result? Does it look correct or not?

When you are connected to your modem. Use ping to get the IP address for sites that you can not access while you are on local telecentre servers. Write those IP addresses down. It could be the DNS servers on the local telecentre servers do not have the IP address of the web site(s) you are trying to access. You can do a temporally fix by placing it in the /etc/hosts file. Sometimes admins gets told to put strict access to certain sites. You can also find free proxy servers and then use them when you are on the local telecentre servers.

try going into terminal and super user and then type "killall dhcpcd" without quotations. then when thats done type "dhcpcd -d eth0" or "eth1" or whatever your eth is.... hope this helps!
