I know I am missing something extremely simple here, but I built my new desktop computer, installed Arch, no problems there, but when I remove the Arch Linux Live disk and boot into the OS I can't get ethernet to work?  Works fine with the live disk in but once I am in the OS, nada.

I did run
 # systemctl enable dhcpcd@eth0.service 

That ran without errors but still a no go.  I have never had ANY issues when plugging up an ethernet cable to any Arch linux build I have owned.

So you know I am missing ONE major step and maybe because my eyes just are not what they used to be I missed it.  ;)

Any suggestions are ALWAYS welcome.

Thanks again

Ian

Still have not got the SSD drive on the lappy loaded yet, time has not been on my side.  Maybe next week.

Arch does not use the eth0/wlan0 naming from BIOS any longer, it uses a name provided from udev/hardware detection.
It should be something like 'enp0s25' see the ArchWiki Networking page and scroll down to the Device Names paragraph under Network Interfaces.

You should be able to get it to go with just
# systemctl enable dhcpcd.service

Try disabling the service you show above and run this one without any interface name first and see if that fixes it.

Tweak it 'til it breaks, then learn how to fix it.

I disabled the first service, again no problem there but when I try and enable dhcpd.service is says it does not exist.  Have NEVER had issues getting ethernet to work, that is normally not a problem.

I'm delving into the Network Configuration Arch Wiki to see if I can figure this simple thing out.

You can type
# ip link
to discover the names on your system.
Then you can use
# systemctl start dhcpcd@interface.service
# systemctl enable dhcpcd@interface.service
where interface is the name from the ip link output.

Tweak it 'til it breaks, then learn how to fix it.

Follow what Amenditman suggested... your eth0 should be something like enp3s0

Eric, I promise you have NOT been ignored, and Slackware is all that and a bag of chips, but I am an Arch guy,  I still respect Slackware being the "original" :thumbup:
Am going to try Ameditman's suggestion first thing in the morning.  Just not sure what happened, Arch has always seemed to recognize the network when the ethernet cable is plugged in.  Heck, I USED to have my desktop setup with Wifi, which was a piece of cake.  :)

It's still a piece of cake. You just need to setup you network as discussed in the Beginner's Guide:

We all have to admit that Slackware must be really stable and easy to keep running smoothly.
How else would Eric have so much time to admin forums, pad his post count, write all those blogs, and write detective stories?

Hey, maybe if I ran Slackware I could have a life also!

Not just that, but for cats in particular ;) they like things that don't move around a lot. You know, like having to pull out the system and put in all kinds of new shiny stuff, etc. ;)

Debian's boring (my friend, though, says, "Boring is good"). :P

So I also run Arch and Sabayon, where updates might break something.  :Muahaha:

Even though I'm an old cat.

I think what Fran means when she says "moving" is like rearranging furniture and stuff like that. My cats hate it whenever I move stuff around in my house. The grumble and give me angry looks for days afterwards. It's like rearranging the furniture at Helen Keller's house. They just like things to stay the same.

I have not had anything break in a really long time plus I do the weekly clonezilla backups just in case.

Ok, up and running  :)  I was pretty much right the first time except for the fact I used eth0 instead of enp2x0x

# systemctl enable dhcpcd@enp2x0x0.service

Still have some tweaking to do but so far I was able to get my official and local packages from my laptop installed on the desk top.  Now to see how ard it is going to be to run video from both the Nvidia video card and the AMD on board video to get the 3 monitors going.  Won't be touching this until next week.  HOPEFULLY this week I can start the install on the SSD drive on the laptop.  Yeah, that was a few weeks ago and life just seems to get in the way  ;)
