Hi

I have just installed fc4 on one machine, i was trying to configure it as a local server in my office, when i did they every thing is working fine, Samba, Httpd, sendmail, dovcort....

but i am unable to browse internet on my linux box. and that is why my yum install is also not working....

Please help, what could be the problem... i dont have a linux admin in my office.

what do u want to do with ur fc4, make an internet service server or just want to surf at ur linux box ?

What type of internet connection are you using?
If you have a cable or DSL connection, have you tried enableing or activating your network?

(In Gnome: System > Network)

Well thanks you both first of all that you could find to answer me...

Well in my office we have a firewall PC on which we have DSL conenction and that is our default gateway 192.168.1.1, we already have a linux machine but it is very old so we decided to make a new faster PC for linux. so i installed fc4 on a new PC, and setup smb, dovcort, httpd, etc, and everything is working and hopefully we will be shifting our work to this new PC soon. but the problem is i can not access net on this PC dont know why.... but because of that i can update my yum repository. i have to install some external php libraries but whenever i try yum install... it stops.

Please help!!!!

please print the exact output and command with which you run yum.

Have you tried pinging the other machines in the network?

hmmm... the exact details would be useful. I also recommend printing the output from
ifconfig (-a for all I think? can't check right away...)
and
ping 192.168.1.1
and perhaps also a ping of whatever dns you're using. It sounds like something isn't properly configured, which could possibly also be a proxy.

farslayer · 10-13-2006, 02:06 PM

also post your DNS server settings and default gateway information..

route

cat /etc/resolv.conf

No default route or no working DNS server and you won't be surfing the net.. silkenphoenixx already coverd the network card settings.

Hi

This is the output of cat /etc/resolv.conf

Quote:

; generated by NetworkManager, do not edit!

; Use a local caching nameserver controlled by NetworkManager

nameserver 127.0.0.1

I tried to ping 192.168.1.1 and other machines too and it worked. and we are not using any proxy in out network. dont know why i can not access internet on this server.

And this is i get when i try yum

You have not set up your nameserver. The entry that you see in /etc/resolv.conf is the default entry during installation.

Pinging your local network machines will work perfectly. But when you try to connect to the outside world it will show name resolution error.

My /etc/resolv.conf is set to the router address...(and it works)

farslayer · 10-16-2006, 10:04 AM

You will definately need to edit that file /etc/resolv.conf
You do not have an IP address in there for a DNS server so your machine cannot resolve names.

To test this theory you could try browsing to a website via IP address...
Yahoo.com http://209.73.186.238
Google.com http://72.14.203.99

If those work then your Only problem is your DNS server settings.
You can try entering the IP address of your Broadband router as linmix suggested
Check what the DNS settings on your Windows machine are

Quote:

START -> RUN -> cmd -> <OK>
ipconfig /all

Or You can directly enter the IP Addressess of your ISP's DNS Servers..

nano /etc/resolv.conf

This is the output of my ipconfig /all

I edited my /etc/resolv.conf and now its

[root@spandan ~]# cat /etc/resolv.conf

I tried to browse net using IP addresses too as suggested by farslayer but my browser gave "The connecting was refussed when attempting to connect 72.14.203.99"
