More Verizon DSL help needed

[akira28]

My problem: DHCP fails when using netcardconfig. Card works fine under Windows XP.

My system: SOTEC laptop running Knoppix from CD.
ethernet card: SiS900 (notorious?).
Laptop is connected directly to modem (no router - yet)

I have unsuccessfully tried the following remedies found in this forum:
booting with noapic
ifconfig -a lists lo and eth0
initial probe says: eth0 sis900 PCI fast ethernet at 0xd000, IRQ11...
modprobe sis900

Only questionable line in probe was "can't locate block-module-2" (not sure if meaningful to my situation).

Thanks for your input.

What kind if modem? That's cruicial info.

Post the entier output of ifconfig -a please. Don't worry if you have a long post- details are good.

modprobe sis900

Do lsmod

Here are two (http://www.knoppix.net/forum/viewtopic.php?t=1012#8593) posts (http://www.knoppix.net/forum/viewtopic.php?t=1115) related to your NIC- dunno if they're going to be of any help.

Not related to your internet problems, it simply can't find the floppy drive. Do you even have a floppy?

Oh adsl eh? That particular modem (from what I've read) has it's own DHCP server built in. Very cool if you want to build a home network.

Hmmmmm- the s900 module is loaded but not in use. Add the following to /etc/network/interfaces:


auto eth0
iface eth0 inet dhcp
up /sbin/ifconfig eth0 mtu 1412

As I understand it you can't have an MTU of higher than 1412- yours is set to 1500 (standard) but I guess that won't work. Have you used the ADSL/PPPOE configuration tool? It can be found here:

Kmenu>Internet>Connect>ADSL/PPPOE configuration tool

Normally I do use this tool but I didn't when I went in to get the above info for this post.

I'll try this tonight when I get home and post the results.

Is this correct? Or is there something else I could try. Would a router (wireless perhaps) be a better work around?

The module is loaded and in use now try 1492 for the mtu in the line:


up /sbin/ifconfig eth0 mtu 1412


you can see that is what is trying to use in the ppp0 and ppp1 although you have two interfaces I don't think this normal but I'm not positive I have never configured PPPoE. If you still have the two interfaces and it doesn't work use ifdown ppp? just take one down then the other to try a different combination to try to get it to work.


Also if you did not have the lines:



auto eth0
iface eth0 inet dhcp


already in the file then you may want to try commenting out the up line bringing up the interface with the mtu settings that may be causing the second ppp interface.

[akira28]

OK, so far this is what I have:

I have tried editing the /etc/network/interfaces file with: 1492, 1452, and 1412. I also tried leaving out the up line altogether to no avial. DHCP is still failing upon setup.

Also things seem to be a bit unstable. PPP0 seems to appear and disappear. It also shows up sometimes as ppp1 or ppp2. When that happened I followed with ifconfig ppp_ and I received a "device not found " error.


Here I try to run netcardconfig which seems to stop eth0 from running:

Here I am starting eth0. But notice ifconfig -a and ifconfig ppp0. ppp0 doesn't showup with -a :

Next I try netcardconfig again but eth0 stays running this time. Also note ppp0 is back and has now changed to mtu 1500:

I'm out of ideas except you should post this to debian-user@lists.debian.org you should be able to hopefully find someone there to help, they love a good challenge and I definetly think you got one for them. Post as much detail as you have here they like to see someone has made the effort to figure it out. Although I would leave out the works fine with XP line. :wink:
