Lost Network (Internet) Connection Overnight on Slackware 14
 

Hey. I'm running Slackware 14 on a desktop machine. I installed it about a month ago. I've had no problems connecting to the network/internet, until today.

I'm a relative newbie and know little about networking. My box is connected, via cable, to a switch, which is connected to a wifi router, which is connected to a cable modem.

I run three machines off of the switch. The 2 other machines are connected and running as they should be. I booted my Slackware machine today and found I couldn't connect to the internet.

As I mentioned, this has never been a problem.

I thought it had to do something with changing of the clocks, so I changed the machine time by one hour and rebooted. Still no connection.

Here's the message about my network interface during the boot process:

Here is ifconfig:
And here is what I get after for dmesg | grep 'eth0':

Any suggestions?

Thanks...

You are not getting an IP address from your DHCP server.

How did you configure the eth0 the first time?

Did you use the script as root, netconfig ?

Are you using WICD or Network Manager?

Have a look at what ever you used, and see if you can see what has changed.

Netconfig as root, is very easy to use. You can get a lot more information on network config in this document. -->http://docs.slackware.com/slackware:...e_your_network

Hope this helps.

I forgot to mention my initial configuration. I used netconfig during installation. It's set up to receive an ip address via DHCP. I also set up a hostname and domain. But that was it. It was, essentially, plug and play.

I made rc.networkmanager executable today. I've the associated widget on my KDE desktop. It lists 'Wired connection 1.'

You probably already tried this, but, what happens if you restart your network immediately after booting and receiving those errors?

Occasionally my pc displays connection errors on boot too, however, a
/etc/rc.d/rc.inet1 restart
resolves the problem immediately.

Also back when I was using Debian I sometimes had to run dhclient to get an IP address. Never had to do so in Slackware, but maybe it's worth a try.

It turns out, the issue originated with my wifi router. It was limited to leasing a small number of ip addresses and I went over the limit this weekend. I changed the value and the Slack box is working fine. Thanks for the suggestions.
