Cable Internet through LAN


Hey, I can't connect to cable internet though linux!!

I've skipped configuring it because some people were helping me before, but they must have either given up, forgotten, or didn't know what there was to fix. So now, I can start with a clean slate.

So, how do I configure Internet access?? Starting from where you identify the ethernet card, to where you connect to the internet??



VITAL INFO:

DISTROBUTION: Mandrake 9.0
ETHERNET CARD: Olicom OC2325

Well, it really should be very easy (in theory)

If the pc is connected directly to the cable modem via an ethernet card all you should have to do is tell the ethernet card to get an Ip address via dhcp.

That's assuming of course your ethernet card is working, ( or is that the stumbling block )

Well, I have an eth0 interface, and linux recognizes it. When I set up my internet, i tell it my hostname (which is ****.wowway.com) and I set it up to use DHCP. It has a netmask automatically, and I leave that alone.

I'm connected to the internet through a network hub if that makes a difference.

Wait a minute... the hostname refers to the computer that I am on, and not the WOW computer that I connect to to get internet, right??

If you set a hostname it applies to the compuiter you set it on and no other, yeah and no other device/computer will know about that hostname unless you tell them explicitly or setup dns (forget about that though)

Do do what? If you're you're sure your card is good to go, or look in and uncomment the approrpiate entry in /etc/rc.d/rc.modules (reboot)

Slackware

/etc/rc.d/rc.inet1

USE_DHCP=yes

(the first one)

unless you updated everything then its in something like /etc/rc.d/rc.inet1.conf


Remember though if you are usng a hub only one computer at a time will access the internet unless you got more than one ip from your ISP or are usng NAT. Reboot your modem every time you change network card thats connected to it

Based on the card you mentioned Olicom OC2325 and a quick search

in

/etc/rc.d/rc.modules

uncomment


/sbin/modprobe tlan

reboot

K, so I uncomment /sbin/modprobe tlan in /etc/rc.d/rc.modules, and I add USE_DHCP=yes into /etc/rc.d/rc.inet1, right?

Also, should USE_DHCP=yes be before or after any particular entry in /etc/rc.d/rc.inet1 ?

USE_DHCP=yes

first of all

1: what is the ip address you are getting from the dhcp? is it a internal range (10.*.*.* or 192.168.*.*)??
2: can you ping your gateway? (do you have one setup) if you are running a router (network HUB) with NAT then typically your gateway is the ip of your router (typically 192.168.0.1) go into the management software of your router
3: can you ping any websites? (www.google.ca) add your DNS servers to resolve.conf "nameserver 232.232.232" <-- whatever it is.

i think you would have a better time taking the router off completely and directly connecting the linux box and see what your internet provider gives you for an IP gateway dns etc. then see if you can surf. if you can then look no further it's the router it's mis configured.

Okay, I did whatcha said, Looking_lost, and I got this error:

Timed out wating for a valid DHCP response

Do I need to give it a hostname? if so... What is that?

I know that my ethernet card on eth0 is working, but I can't ping or get on the internet.

(BTW, pedscham: I can get on the internet through the router when I am on windows, just not on linux)

(BTW, Looking_Lost: Sorry about the confusion, I didn't realize that the commands were simply commented out)
