RH 7.1 and adsl

[lelandmyrick]

My great frustration in using linux so far has been my utter inability to connect successfully to the internet.

I've installed 7.1, gone through the internet config in the KDE desktop where I chose the adsl option and then set my dns info. When RH starts up, it shows adsl connecting no problem, but when I open Netscape or Mozilla and point to a site it just sits there and whirls away going nowhere.

What am I doing wrong?

Did you configure a firewall when you installed? Maybe you are blocking access. Can you ping or traceroute any internet address?

What does this show:

/sbin/ifconfig

and this:

/sbin/route -n

and

cat /etc/resolv.conf

I set security to medium (the default) during installation. When I try ping I get a 'host not found' error.

You don't have an ethernet card configured, according to ifconfig. You can use netcfg ( redhat's thing I believe ) or netconfig ( that's what i use with slack ) toconfigure it, or you can do it with ifconfig if you know the info to add. I'd suggest to just use netcfg, get it to find the device and tell it to autoconfigure it with dhcp, and everything should work.

Unless he is using an internal adsl modem. Look at the IP address that can't be right. Although have I seen some xDSL providers use non-routable ip's.


inet addr: 10.112.112.112 P-t-P:10..112.112.113

Leland, what are you using an internal or external modem?

>Leland, what are you using an internal or external modem?

It's an external Efficient Networks, Inc. Speedstream DSL modem.

I think the ethernet card (built into the board) may be part of the problem. It wasn't recognized during installation.

I am considering going down to Fry's today and getting a cheap ethernet card and trying a reinstall of RH. Does that seem like the best place to go from here?

[JimH]

No reason to reinstall. Do you know what NIC is built-in on the motherboard?

It's an SiS 900 PCI Fast Ethernet Adapter built into an ECS K7S5A motherboard (put the machine together myself).

[JimH]

Well, the SIS900 is supposed to be supported, maybe your revision isn't. Try this to see if you can get it working.

You will need to be logged in as root.
Open /etc/modules.conf in a text editor, add this line

alias eth0 sis900

Save the changes and exit. Then at the shell prompt type:

modprobe eth0

See if you get any errors. You can see what modules are loaded with:

lsmod

>Open /etc/modules.conf in a text editor, add this line
>alias eth0 sis900
It was already there

>modprobe eth0
I get 'can't locate module eth0'

>See if you get any errors. You can see what modules are loaded >with:
>lsmod
It shows no modules loaded. Shouldn't there be an eth0 module loaded?

Thanks for all the help so far!
