cannot connect to internet after update

**ukwho** · 02-08-2009

Hello,

I have just installed Fedora 10.

After the installation I was able browse the Internet. However, I did a update: yum update and downloaded 287 updates.

However, when I rebooted I could no longer connect to the Internet.

I went to network manager and looked at the details of my connection. Everything ok there. IP address, DNS, etc. However, I cannot connect. I have windows xp running on the same system. I can still connect, so there is nothing wrong with my Internet connection.

I am using Fedora 10 2.6.27.12-170

There is one thing I have noticed when I shutdown is I see this:
"Network manager Int PIC disabled" However, this is only displayed for a few seconds before the computer swiches off.

I looked at the other post. And got this information from what was posted. This is the first time I am using Fedora Linux. So not sure if they is anything suspious that should be fixed.

Many thanks.

Hello and welcome to Linuxforums.
Start the system back up and open a terminal window, login as root.

Code:

su -

(enter)
(password)
(enter)
Type this command

Code:

system-config-network &

Try setting the eth0 device to activate on boot, then reboot and see what happens.

**ukwho** · 02-08-2009

Hello,

I entered the command and edited eth0 so that it will activate when boot.

However, after I restarted I still couldn't connect to the Internet.

When I hover my mouse over the network manager in the task bar. I get the follow message "Wired network connection 'system eth0' active.

So i think the network manager seems to be ok.

Could it be a security setting that doesn't allow me to connect?

Many thanks,

Is the device set to use DHCP?
You might be able to go back to the previous kernel and wait a few days to see if maybe this is just a bug or maybe some package that you need didn't get released in time for the updates, which sometimes happens.
Can you post the output of

Code:

/sbin/ifconfig eth0

**ukwho** · 02-08-2009

Hello,

This is the results:
eth0

I have pinged the gateway: 192.168.1.1. And that is ok, as I always get a reply back.

I have tried rebooting in the previous kernal 2.6.25.5.117.fc10.i686
I still could not connect to the Internet.

If this is a bug, it would be difficult to get an update, when I can't download as I can't get connected.

Many thanks for your help,

Hmm, this makes not much sense to me, it appears that you have an IP and everything.
What's in /etc/resolv.conf

Code:

cat /etc/resolv.conf

I've not used Fedora since Fedora 8, but I seem to remember SELinux giving me a heck of a time. Is this disabled? Run, as root,

Code:

system-config-services &

and check there.

Hola Jay!
I suddenly remember selinux gave me fits on FC9, which is why I always rip it out by it's guts!

***jayd512*** · 02-08-2009

Howdy, Mike!

Yeah, anytime I did a Fedora install/upgrade I usually dump SELinux before anything else!

**ukwho** · 02-09-2009

Hello,

I opened up SELinux. However, I can see all the services that are running. I am not sure which ones I should disable or enable.

I was thinking about removing SELinux. However,
yum remove selinux
needs to connect to the internet to remove this.

Is there a way to actually stop selinux or to disable it?

Thanks for anymore suggestions,
