Networking Problems

Arcturus · 2007-12-24 21:22:46

Hey,
I'm new to Arch Linux, and I just set it up with the help of a friend of mine. Everything seems to be okay, except that I can't set up my internet properly. I'm behind a router, and I have any info needed to solve the problem (as far as I can tell). Inside rc.conf, I've changed eth0 to "dhcp". That's pretty much everything that I've changed, but whenever I try to ping a site like google it says "unknown host".

Any help would be appreciated.

after you set dhcp in rc.conf did you restart networking?

Can you post your /etc/rc.conf file for us?

If you have right modules for your ethernet card loaded and use something like

lo="lo 127.0.0.1"
eth0="dhcp"
INTERFACES=(lo eth0)

in '/etc/rc.conf' assuming you have DHCP capable device it should assign you IP upon doing '/etc/rc.d/network restart' as root.

Simply do 'ifconfig' to see status of your ethernet devices. If you see output like

eth0      Link encap:Ethernet  HWaddr 00:18:F3:73:80:17  
          inet addr:192.168.1.34  Bcast:192.168.1.255  Mask:255.255.255.0
          inet6 addr: fe80::218:f3ff:fe73:8017/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

          TX packets:1413675 errors:0 dropped:0 overruns:0 carrier:0

          Interrupt:16

this, you hw is somewhat recognised. Else you have to get proper drivers.

Have you tried to ping the router itself?

Arcturus · 2007-12-25 16:07:57

Yes, I've restarted, here is my rc.conf file:

LOCALE="en_US.utf8"
HARDWARECLOCK="localtime"
TIMEZONE="Canada/Eastern"
KEYMAP="us"
CONSOLEFONT=
CONSOLEMAP=
USECOLOR="yes"

MOD_AUTOLOAD="yes"
MOD_BLACKLIST=()
MODULES=(e1000 iwl3945 snd-mixer-oss snd-pcm-oss snd-hwdep snd-page-alloc snd-p$ snd-pcm snd-timer snd snd-hda-intel soundcore)
USEVLM="no"

HOSTNAME="arcturus"

lo=lo 127.0.0.1
eth0=dhcp
INTERFACES=(lo eth0)
gateway="default gw 192.168.0.1"
ROUTES=(!gateway)

DAEMONS=(syslog-ng network netfs crond)

If you guys need my ipconfig, I can post that too.
Thanks,

You're on a wired connection right?

Try pinging yourself, and then your router. (Usually 192.168.1.1 for most household routers) If both of those pings work, you know the problem is between the router and your isp.

What kind of internet service do you have? If you have DSL, you may have forgotten to set it up properly? (I believe there are extra steps to a dsl connection, correct me if I'm wrong please.)

I get "Network is unreachable" when I ping my router. I'm on a wireless connection.

dante4d · 2007-12-25 17:59:49

Post your 'ifconfig -a' output. Btw does this make difference?

lo=lo 127.0.0.1
eth0=dhcp

vs.

lo="lo 127.0.0.1"
eth0="dhcp"

wireless!

The new Arch setup for wireless is netcfg2, please configure your wireless network with that:

Oh and btw arc, its r4ndom here incase you didn't know. The problem you were getting when installing packages is because you NEED to capitalise the S as in:

pacman -Sy xorg

as opposed to

pacman -sy xorg

anyway I would use wired connection first to set up everything and tailor my wifi... But he's probably got that working...

Arcturus · 2007-12-26 23:36:48

Okay, I've set up a wireless profile using netcfg2, and it appears that I am connected to my network. However, I am still experiencing no connectivity. Here is some relevant information:
