help me set up DHCP with this sis900 card

Hello all, here's come another network newbie question... I've just installed Knoppix on a hard drive, so essentially it is Debian. I've did my homework and tried to read previous posts; but no luck. I have a dual boot system, Windows XP boots and loads network parameters with no problems, it automatically obtains all the network values from my cable modem. Knoppix, on the the other hand, is being a bit of a pill. I like the idea that its debian and I like the distro. Think the drivers are being loaded correctly (sis900), but i'm not entirely sure. So here's my "ifconfig eth0"

Code:

---

root@chad:/home/knoppix# ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 00:40:CA:49:8E:68
          BROADCAST PROMISC MULTICAST  MTU:1500  Metric:1
          RX packets:1324 errors:0 dropped:0 overruns:0 frame:0
          TX packets:10 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100
          RX bytes:82646 (80.7 KiB)  TX bytes:3420 (3.3 KiB)
          Interrupt:19 Base address:0xec0

---

what does PROMISC MULTICAST means?

... and output from "lsmod"

Code:

---

root@chad:/home/knoppix# lsmod

and here's my "interfaces" file

Code:

---

root@chad:/home/knoppix# cat /etc/network/interfaces
# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

# The loopback interface
# automatically added when upgrading
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

---

please help....

Everything looks good it is just not getting an IP. Have you tried pump -i eth0 or dhcpd eth0 to see if you can get the IP from the cable modem? Both commands would be issued as root user.

okay, i've tried the commands you've suggested
pump -i eth0 gives me this:

Code:

---

root@chad:/home/knoppix# pump -i eth0
failed to connect to localhost:bootpc: Network is unreachable

---

as for dhcpd eth0, i don't have dhcpd, but i do have /usr/sbin/dhcpd3. so here's the output with dhcpd3...

Code:

---

root@chad:/home/knoppix# /usr/sbin/dhcpd3 eth0

i'm beginning to think that the driver that KNOPPIX is loading doesn't work, if you look at my first post, in lsmod output, you see "sis900" and nothing besides it, meaning it is unused or perhaps configured incorrectly.

please help trouble shoot this further...

Hey man, I have that SAME PROBLEM! When I used Knoppix 3.2 on my other computer, I was able to connect through my router JUST FINE. No set up necessary.

Now I try Knoppix 3.3 on another computer, and I cannot connect. I know that my network card (linksys) is recognized correctly, I tried a BUNCH of stuff, but in the end I couldn't get it to work. Yes this is with a HD-Install of Knoppix. I planned on upgrading my stuff with Debian programs, but I can't get online to do so :(

I decided to just leave XP on that computer, since I was just using it as a file-sharing computer anyways...

I would suggest you to try Knoppix 3.2 instead of 3.3? Maybe that will work for you. I like 3.2 better anyway, it comes with a task manager (for when programs freeze), AND it has QTPartition (3.3 probably has it I just couldn't find it. I wasn't on 3.3 that long so its possible it has it.)

Look around this board man

http://www.knoppix.net/forum/viewtop...asc&highlight=

It seems like 3.3 has problems with networking. like I said before, 3.2 worked fine with another computer using the same router!

My suggestion, use 3.2.

Thanks dodge for your input, but i'm not ready to give up so soon...

Perhaps you can post your lsmod as well as the contents of your interfases file, and if you can the ifconfig eth0 output.

we can get through this together!

You are correct the zero beside the module means it is not in use. Could you post the output of lspci -v and dmesg | grep eth0 so I can see if the card is detected properly also a few more details on the hardware in the computer could be helpful. Also have you went in the BIOS and disabled the Plug'n'Play OS setting if it has one? When you get your settings from the network do you have a direct connection using DHCP or does your ISP use PPPoE? On my network I have the option of using either static or DHCP settings can you do similar? Another question did knoppix connect from the CD before you installed to the HD and what version did you use? Basically post as much information as you think is relevant and one more thing have you tried to run netcardconfig again after the install?

Heh, sorry man I already gave up along time ago ;) I already reformatted the harddrive and set it up as a secondary harddrive to my Windows XP drive. I might mess around with 3.2 this weekend to see if that fixes it...depends on how much work I have to do :(

So yea, unless you can find a fix before this weekend I will be happy to try out 3.2 for ya at the end of the week ;)

good idea,
so i'm Knoppix 3.3 on P4. The computer is connected directly to my cable modem. Windows partition obtains all the network information through DHCP clien from the modem, so I assume the modem is broadcasting it without any problem.

Knoppix is now installed on my HD. When I boot from KnoppixCD the network is not recognized either.

here's information from my "dmesg | grep eth0"

Code:

I've also ran "netcardcondig" and it failed. When I looked at its script I saw that its using "pump -i eth0" command which fails as well (see my previous post). So I'm all out of luck!

is it possible that this driver does not work? I think i've red some posts that knoppix has trouble with this driver, how can i troubleshoot this?

is the problem described here beyond the scope of this forum? please suggest any other place where I can find an answer.

Boot the CD with the cheatcode:
