I have been using Linux for a while and have 3 Linux distros on my system. Two of them automatically use GNOME or KDE on bootup and shutdown, and my eth0 DSL works fine with them. The third distro is a new install of Slackware 10 with Fluxbox as my GUI. With Slackware, my eth0 works fine on the first boot out of Fluxbox. When I reboot, the eth0 connection disappears in Slackware.

Could how I shutdown effect eth0?

I have shutdown from the console after exiting Fluxbox using the shutdown command and the halt command. I've also tried the key combo CTRL-ALT-DEL

type lsmod is the driver loaded

type lspci -v and post so i can help you more

Wow-I like those commands! My eth0 is working now-I reinstalled Slackware 10. I must have messed something up installing some files. I figure I'll just leave Slack the way it installed from cd-no changes.

Slackware won't get on the internet again (my other 2 Linux distros do). I have a Netgear FA311 on eth0. I executed lsmod and lspci and both displayed that natsemi (my eth0) is getting loaded.

type uname -a
it will show what kernel is running

? = the kernel number from uname -a
type ls --color /lib/modules/?/kernel/drivers/net

look for you network driver

than type modprobe module name

now to get on line!

type dhcpcd eth0

linuxhippy -- if natsemi is the module your NIC needs and it is being loaded, then it's possible that you just need to bounce your eth0 interface. Try running these commands (as root), which will list your eth0 settings, then bounce eth0.
The purpose of the 4th command is to see whether eth0 has been assigned an IP address. If it has, then you should be all set to surf -- J.W.

dhcpcd eth0


will look for a dhcp server


but you can do this

ifconfig 192.168.0.2 eth0

route add defalt gw 192.168.0.1

that is if you have a gateway at 192.168.0.1

than edit /etc/resolv.conf like this

nameserver 192.168.0.1
domain home

this is strange....sometimes my DSL work in Slack and sometimes it doesn't work in Slack (always works in my other Linux Distros). I think it's because my pc doesn't shutdown all the way by itself from cli. Eth0 will work till I power it down. When it's done the shutdown processes and the red light on my harddrive goes out, then I hold in the power button till the pc shuts off. When I power it back up, eth0 doesn't work in Slack till I boot into another distro and connect. Then it works in Slack when I reboot.

ifconfig only displays lo till I take it up and down (like J.W. suggested), but I don't get the server assigned dhcp addy. Here what I get:

eth0 Link encap:Ethernet HWaddr 00:40:F4:4C:F0:80

When I type dhcpcd eth0 my pc freezes till I press CTRL-C

When I assign a previously assigned IP addy, I get an error.

Any more suggestions?

It may be that the DHCP daemon process isn't running. Try this
That will restart the DHCP process, and should assign an IP address to eth0. As you've already indicated, the system may just sit there a while, apparently doing nothing. If you don't get returned to the prompt, hit Ctl-C. Check ifconfig again, and you should see an IP address associated with eth0; if not, try bouncing eth0 again using the down and up options. (Side note: attempting to reuse a previous IP address is sure to fail under DHCP, due to DHCP assigning addresses dynamically, meaning randomly. The only way you could successfully reuse an existing address would be if you had a static IP connnection, in which case that would be the one and only address you could ever use.)

In any event, I'm a bit surprised that you're finding it necessary to run these steps manually - my Slack installation the best-performing and most stable thing I've ever used, and I'm not sure what might be causing this periodic conflict that you seem to be encountering. Good luck with it -- J.W.

Thanx J.W.-the command you suggested worked after about 30 seconds of silence:

dhcpcd -r eth0

I'm now online with Slack (hopefully for good)!

I shutdown to see if my eth0 settings would keep and they didn't. When it restarted I typed:

dhcpcd -r eth0

After I sall from ifconfig that eth0 wasn't present. After two tries it works again. How can I save these eth0 settings so that my ethernet card and dynamic IP addy is set up when my pc boots?
