Newbie needs help to configure router

TheSwine · 01-01-2004, 07:20 PM

I'm trying to make my linux box to work with my new Netgear DG834, but the more I try, the less I understand what is going on... (Netgear are asking 1.99$

per minute for Linux Support

, so I though I'll try here first.)

My Debian is installed on a dual-boot laptop, and with Win98 everything works just fine.

My router is configured as DHCP server. It cannot see the linux box (i.e. it does not show it in the 'attached devices list'), but it does assign an IP for it (192.168.0.2).

I can ping the router and other LAN computers, but do not seem to be able to ping anything outside my LAN. Also, I cannot access my router (192.168.0.1), let alone access the internet.

I'm sure I'm missing something, but haven't got a clue what...
I hope one of you can help.
Thanks in advance.

Here is some stuff that might help:

Code:

(Please note that for Win98 I didn't had to specify any DNS names, these are configured in the router, which I think act as a DNS server simply by forwarding DNS request to the actual DNSs)

try setting your gateway for 192.168.0.1

How, where and for which destination?

Hi ya,

Try looking in the directory /etc/sysconfig/network-scripts

for a file ifcfg-eth0.

Maybe enlighten us with what is in that file? Poke around in there and if you find a file ifcfg-slip maybe that could be of use as well?

(BTW I am using an MDK distro but I think that directory is fairly standard location I think/hope :-)

I am not sure why you have that SLIP encapsulation coming up there between you and the router. Very weird!! Don't you want TCP/IP over ethernet as the protocol to your Netgear router? You could always trying turning it off (i.e. interface <slo>) with <ifconfig> and see if that helps!!

Sorry I can't help more. Could do with some more information from your <network-scripts> directory!!

BTW your default gateway is via 192.168.0.1 (i.e. your router). Try using <ip route> instead of <route> (which is now depreciated anyway) its output is readable by human beings!!

to do it temporarily ->

"route del default"

&&

"route add default gw 192.168.0.1"

Disable slip and you should be able to access the router.

TheSwine · 01-02-2004, 02:16 PM

Bill Gates 666:
There is no /etc/sysconfig/network-scripts under Debian, /etc/network/interfaces is the Debian substitute...

I don't know what that Slip is doing there, nor where did it come from.

ip route doesn't seem to work for me - bash: ip: command not found

jago25_98:
What you suggested with route didn't do the trick.

michaelk:
How do I disable slip?

Everyone:
I can't seem to get /etc/init.d/networking restart to work. (networking is in the folder but: bash: networking: command not found) does anyone know anything about it?

Thanks for your time guys...

An update:

I've tried ifconfig sl0 down, but still can't access my router...

TheSwine · 01-02-2004, 07:07 PM

I've installed DHCP3-client

reboot
ifconfig sl0 down
ifconfig eth0 down
dhcilent3
ifconfig sl0 down

And everything seems to work: Can access the router, ping linuxquestions.org, browse the internet etc.

Few more problems though:

* I still need to do this manually after every reboot.

* dhclient3 creates eth0,eth1,lo and sl0 - I don't understand why do I get eth0 and eth1 when I only got 1 NIC card (eepro100)

* Still don't know how to get rid of sl0

Can anyone help?
Thanks.

TheSwine · 01-02-2004, 07:50 PM

Well... To get rid of sl0 (SLIP):

dpkg --purge diald

(see http://www.faqchest.com/linux/DEBIAN...313_20713.html for more information)

And it seems like everything is working now.

Thank you all!
