Internet problem(knoppix-->router (smc)--> broadband r

[el_hefe]

Hi,

i've searched every forum but didn't find anything that solved my problem. I'm a complete n00b with linux, and the first problem i encounterd was that my internet/network was not working.
We have a network at home with 4 computers connected to 1 router (a SMC Barricade) that shares broadband internet. the network/internet is working well under windows but doesn't unde knoppix.


- i tried to run PPOEconf but it says:

"Sorry I scanned 1 interface,but the Access contrentator of your provider did not respond. Please check your network and modem cables. Another reason for the scan failure may also be another running PPPoe process which controls the modem"

- next thing i did was running netcardconfig:
It asks me if i want to use DHCP broadcast (i have no idea what that is)
yes-> the program stops ( it says dhcp failed or something)
no -> It asks for :
-IP address for eth0/eth1
-network mask
-broadcast address
-default gateway
-nameservers

i read something about editting lines in /etc/network/interfaces (?) but don't know how.


from the router status page:

GATEWAY
IP Address: 192.168.2.1
Subnet Mask: 255.255.255.0

INTERNET
Cable/DSL : CONNECTED
WAN IP: 217.120.139.127
Subnet Mask: 255.255.254.0
Gateway IP: 217.120.138.1
DNS: 213.51.129.133
Secondary DNS: 212.120.66.194

My local ip: 192.168.2.27
adapter: CNet PRO200 PCI Fast Ethernet Adapter #2

So: what numbers do i have to fill in where?


tnx

Hi,
i had no dsl or ethernet connection.
I ran netcardconfig in the /usr/sbin drawer.
I kept going and ran pppoeconf
I got error messages etc.
I picked no instead of yes in the process somewhere
and it came up with a list of drivers/components.
I picked the ppp on ethernet (pppoe)
and let it reinstall.
Viola! my internet works!

Sorry, I can't be more specific.

- i tried to run PPOEconf but ...

Your SMC box is taking care of all the PPPOE stuff for you, you do not need (or want) to use PPPOE on the Knopix system when you go through this network.

I just ran a test and Knoppix works fine with a SMC "Barricade" router. If you can't just boot up and get a DHCP connection, you might have some other problem (like the problem I've seen and reported here where other evil software seems to have deliberately reconfigured your NIC's EEPROM so Knoppix will fail). If you can't get to the network after a boot, try the following and report back your results:

From a shell, run ifconfig and report the settings

Ping 192.168.2.1 and see if you get a response

If you do get a ping back, try to open 192.168.2.1 with a browser and see if Knoppix can talk to the Router. Be sure that you haven't disabled this IP address from internet access or put time limits or other restrictions on it.

Try the commands sudo mii-tool -r and the netcardconfig from a shell prompt and see if that helps, try pinging 192.168.2.1 after the netcardconfig and check ifconfig again. You might also want to see what mii-tool tells you without the -r (reset) option.

thanks for your help!
i tried your suggenstions but it doesn't work, it seems it doesn't support my networkcard :S but when knoppix starts it says that he detected a card: eth0.

this is what happend:

-knoppix@ttyp0[knoppix]$ ifconfig
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:16436 Metric:1

-knoppix@ttyp0[knoppix]$ sudo mii-tool -r
SIOCGMIIPHY on 'eth0' failed: Operation not supported
no MII interfaces found

-knoppix@ttyp0[knoppix]$ netcardconfig

Hit return to exit.

i tried it a couple of times but nothing happend

Yes, it sounds like you are havoing trouble with the NIC (network interface card). It might be that Linux does not support it, it might be something else (see my last post). I have real doubts that it's a Linux support issue. You don't seem to be saying what your interface is, if you would tell us someone likely would know if LInux supports it. (If you don't know you should be able to get to information from Windows->control panel->system->device manager->network adapters)

You might also just try putting another NIC in, they can often be had for $5 or free after rebate at OfficeMax, Staples, CompUSA and similar stores. But if you are running something that disabled the last NIC then this might be a temporary fix until it happens again.

One more thing you can try (this makes little sense, but it works for me!):

Boot Knoppix. When you get to the boot prompt, do an expert boot. Answer n to the half dozen questions you are asked (specifically, do not let it do the autoprobe in the first question). See if you network connection works now after Knoppix finishes booting.

If all else fails, see http://www.knoppix.net/forum/viewtopic.php?t=2164

i did say in my startpost what my network adapter was..:

CNet PRO200 PCI Fast Ethernet Adapter #2

i'll try the things you suggested.

Opps, you sure did, sorry I missed it.

I can tell you for certain that Knoppix works fine on a CNET PRO200WL PCI NIC (and with an SMC Baracade too). I'm not sure what the #2 is telling us, or even certain that your CNET PRO200 and mine use the same chipset, but I really think it's the thing I covered in the other link. Please let us know either way.

too bad. so you´re saying that microsoft editted my NIC someway it doesn't work with linux?, i'll try one more thing, i'll put an old NIC in.

update:

I didn't mentioned that my soundcard doesn't work either, but is detected by knoppix, i also see in kmix a tab sblive! but when i try to play a sound with trough de winamp look-a-like it doesn't do anything, the device is set to default and is grey it should be sblive! i think. The NIC is also detected by knoppix in the startup screen, I also see a line: "eth0: media is TP" I don't know if that means anything.


things i tried:
-i tried to run knoppix on exactly the same computer (also win XP) but with another soundcard... internet wouldn't start also the soundcard didn't work.
-i tried to run knoppix on another system (win xp) with another NIC and soundcard (onboard), everything worked well, how it should be.
-other irc setting
-other (very old)NIC, it works under windows and is detected under knoppix but won't work either.

i don't know if this is any help to you for helping me and your own problems. I don't have a clue what to do, to make my computer run properly with knoppix.
