Trouble with a wired connection on my fresh Arch Linux Install

I am a new Arch Linux user. I used to use Ubuntu exclusively, but I'm to the point where I can no longer stand a lot of the issues with the new development and Canonical. Anyways....

I have a Dell Inspiron 1440 laptop with an RTL8110SC (Module R8169) Ethernet port. (Pardon me if my terminology is wrong; please correct me if it is so I can learn? smile) During the install process with the CD that I made, I had no issues connecting to the Internet. However, whenever I boot into my install, there is no connection. I've tried pinging various web pages and nothing will happen. I know that my hardware is compatible, but I do not know what to do next. I've tried everything under the Wiki's Beginner's Guide and the Network Configuration Guide.

I just realised after I wrote this top portion that it no longer is connecting via CD, either. Pinging is giving me errors about no packets being received.

Please help me with this matter? I would love to start using Arch Linux! smile

Re: Trouble with a wired connection on my fresh Arch Linux Install

As the beginner's guide hopefully states, you need to enable your network. For the lazy:

systemctl enable dhcpcd@eth0.service
systemctl start dhcpcd@eth0.service

Re: Trouble with a wired connection on my fresh Arch Linux Install

I get the following after I run systemctl start dhcpcd@eth0.service

Job for dhcpcd@eth0.service failed. See 'systemctl status dhcpcd@eth0.service' and 'journalctl' for details.

Re: Trouble with a wired connection on my fresh Arch Linux Install

I realised that I was entering these commands with the CD and not on the actual install. I entered them on my install from my hard disk. Both of them ran without trouble and I still have no connection. (Ping cannot establish anything). I ran both as root.

I'm still at a loss at this moment.

@Tomk, I don't have those issues on my install, just the CD

Re: Trouble with a wired connection on my fresh Arch Linux Install

omg... do you not think it would be worth checking anyway, even without an error message telling you to?

Re: Trouble with a wired connection on my fresh Arch Linux Install

I'm doing all of this from an iPod...please bear with me that I can't sit here and type out these extremely long messages on an iPod. I took pictures of my laptop to show what the readout was. If that's not ok, I guess I'll give up on Arch and try another distro.

Re: Trouble with a wired connection on my fresh Arch Linux Install

You need to slow down for a minute and think about this, then tell us exactly what's going on (and I don't mean "the internet is not working"). You said you didn't have an internet connection, but it looks like the dhcp service started fine. Run "ip link" again (after you ran dhcpcd) and tell us the result.

Telling us you're going to give up on Arch and try another distro is not helpful.

Re: Trouble with a wired connection on my fresh Arch Linux Install

Ip link yields the same readout. And I mean this: there is no incoming connection. I cannot ping webpages, download anythig via pacman. That is the exact issue.

Re: Trouble with a wired connection on my fresh Arch Linux Install

About my comment about switching distros: it was on regards to people complaining about using pictures. It's unheartenig that my first arch Linux experience is people getting furious at me for not knowing exactly what I am talking about--I'm explaining to the best of my ability.

Re: Trouble with a wired connection on my fresh Arch Linux Install

Can you ping your gateway? What about a specific IP instead of a domain name (8.8.8.8 is a good one thats easy to remember)?

Re: Trouble with a wired connection on my fresh Arch Linux Install

What is the exact error message when you try to ping google?

What does this command return:

ip addr

And as Pres suggested, can you ping a specific ip (try this):

ping 8.8.8.8

Also check to make sure you have a valid nameserver in /etc/resolv.conf:

cat /etc/resolv.conf

Re: Trouble with a wired connection on my fresh Arch Linux Install

Pres, what does it mean to ping my gateway? I'm still a bit of a novice. I'll be able to try those commands later Pres and 2manydogs, I won't be at my pc for a little.

Re: Trouble with a wired connection on my fresh Arch Linux Install

Ping is a very basic command that is fundamental to debugging networks at the lowest levels.

ewaller@odin:~ 1002 %ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
64 bytes from 8.8.8.8: icmp_seq=1 ttl=50 time=42.7 ms
64 bytes from 8.8.8.8: icmp_seq=2 ttl=50 time=36.7 ms
64 bytes from 8.8.8.8: icmp_seq=3 ttl=50 time=36.8 ms
^C
--- 8.8.8.8 ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 2003ms
rtt min/avg/max/mdev = 36.721/38.782/42.768/2.819 ms
ewaller@odin:~ 1003 %

What we can tell so far..

You have an Ethernet Interface.
You have an Ethernet Address.
You cannot look up domain names (bad)
We are trying to see if you can see other computers if you know their address.  This will tell us if it is a DNS or a routing problem

Re: Trouble with a wired connection on my fresh Arch Linux Install

Not sure why you have two different addresses assigned to eth0. Try removing them and running dhcpcd again.

ip addr del 192.168.1.23/24 dev eth0
ip addr del 172.20.8.199/24 dev eth0
dhcpcd eth0

Also, ping 8.8.8.8 and not 8:8:8:8. Try pinging 10.0.25.10 as well.

Re: Trouble with a wired connection on my fresh Arch Linux Install

Do you have your iPhone/iPod plugged in to the computer?

My iPhone was being registered as eth0 and my normal NIC as eth1 (even though tethering was disabled). Doing the following brought up the dhcp client on the correct card:

systemctl enable dhcpcd@eth1.service
systemctl start dhcpcd@eth1.service

Re: Trouble with a wired connection on my fresh Arch Linux Install

I believe that the problem is with my network. In my dorm, I can never get it to work, but if I go to my school's library, it works perfectly. This whole time it was never my laptop but it was my network.

Re: Trouble with a wired connection on my fresh Arch Linux Install

Do you have to log in through a browser to use the network there?  This is (unfortunately) common at universities.

If this is still for installation, the installation isos have the elinks browser which would work for this purpose.

As you have a network connection, but not wider internet connection I suspect it is something like this.

Re: Trouble with a wired connection on my fresh Arch Linux Install

I don't actually have to log in via browser (Thank God). I have finally gotten a DE on my laptop so I can use nm-applet for my network connections. I left the wire in my laptop overnight last night and saw this morning that it was connected... I can tell you now though that I watched it for an hour before bed and NOTHING was happening other than attempting to connect and it then promptly disconnecting and trying again. I'm not sure what the deal is. I've managed to install the wireless drivers for my laptop so I can painlessly use the wireless network. However, the wireless network goes out a lot...around once a week to be exact, and it's almost always on weekends, so there is no fixing it until the next Monday. Anyway, ignore my ramblings..... I'm still not sure what is going on at this point.
