Can't get Internet Access
 

I've installed Fedora 9 on my previously Fedora 7 machine and I can't seem to get internet access through the browser.

When I open up FireFox, I get the message:
"Failed to Connect" Firefox can't establiash a connection to the server...."

I've tried going to multiple sites, and I get the same message.

The machine is configured with a static IP address on an internal, private network. I am accessing LinuxQuestions from a laptop that is on this same private network (10.3.0.X).

The gateway address is 10.3.0.254 and the DNS Servers are 10.3.0.143 and 10.3.0.145.

I've set these IP addresses for the Fedora machine with a static IP of 10.3.0.99.

I can ping the loopback address 127.0.0.1 without a problem as well as the DNS servers and the gateway address. I tried to ping an address "www.hotmail.com" but I receive the message "Network is unreachable"

Just to eliminate the variable, I've put SELinux into permissive mode and turned off the Firewall, but I still receive the same "Failure" browser message.

Can anyone direct me as to what I should troubleshoot next?

By the information you provided, it's seem that physic link between your computer and Gateway OK as well as DNS Server, and Internet access of your network. I'm thinking about some routing miss configured. Could you post the result of route and ifconfig command?

Here are the results:

Strange.

All seems to be right with the world now. I deactivated and reactivated the NIC card through the Network Configuration GUI and it seems to be working now.

Go figure.

Now do the route command again ;)

If default route isn't set then you'll find it doesn't work ;) If you ever need to (although dhclient takes care of this) just do:

sudo route add default gw $GW-IP-ADDRESS

where $GW-IP-ADDRESS is your routers IP.

Lost my connection again.

This could be a hardware issue.

Or, I notice that the Network Connection icon (the two computers in the upper right hand corner) has a red x on it.

I right click it and I see that "Enable Networking" is checked, but when I click "Edit Connections", and then under the "Wired" tab, I do not see any of my IP address information.

When I run the ifconfig and route command, my correct IP information is there.

Also, Firefox is displaying the "Offline" message now.

Does it all come back if you do:

?

Hi tekmann33,

In your post number #3 in this thread, your routing table miss default routing line so your computer cannot connect to other network (network that difference with 10.3.0.0) as arckane's post no#5

By the time of your post number #6 in this thread, Did you can ping DNS and Gateway? If you not did, just forget about it.

If you still cannot access internet, follow me:

- In fedora 9, Your connection is managed by two difference services: "network" and "Network Manager", you can stop one of them. Here we will disable "Network Manager" in all Run Level and start "Network". To do so, go "System/Administration/Services"

- Reconfigure network in root:
and post the result of
Even after that, you still cannot access internet, run "setup" in root to reconfigure all your network configuration

Yes, the problem did seem to be the Network Manager. Disabling it removed the problem.

Thanks a bunch
