Can't connect to internet through router

[Harry Kuhman]

.... as long as i'm asking for assistance and willing to learn i guess i'm not entitled to be called an idiot.

I didn't try to call you an idiot, rather to call the often suggested but completely insecure technique of counting on MAC addresses for any form of wireless security as idiotic and unsafe. More than unsafe really, as it is completely bogus advice. And I assumed that you would be receptive to the knowledge, or I would not have bothered to post it.

however can you answer any of my questions please?
I couldn't send you the ifconfig because i couldn't paste it on the web browser....

I'm trying to answer your questions, but don't have needed information. While cut and paste makes life simple, there is technology based n a graphite rod bound inside a wooden cylinder that would allow you to accurately record the data from ifconfig and then type it back in to a browser on a different OS. Sure, it's a bit more effort, but if saving to a USB drive or a floppy isn't working for you then the older approach may be the best.

ok that was fun
well for the time being, what i can tell you is that the eth0 is not detected at all before i do netcardconfig. It just gives me 'lo' IPs and settings, but i think that has nothing to do with my problem right?
Btw my hard drives (as probably you may have assumed) are formatted as NTFS, which as advised by most linux distros i have, is not fully compatible with linux but just experimental.

I really don't know what is going on here. You haven't told us what NIC you have. But I would expect that Knoppix must have a driver for it, or else you would not have gotten it to work at all, even after a Netcardconfig. So I would normally expect that it would be properly configured BY DHCP. And in fact you seem to have said that it was being configured by DHCP, but the gateway address was, for some very mysterious reason, incorrect. If that it not what happened then please restate how that bad gateway address got there; if it was configured by DHCP then I don't know why you are now saying that eth0 was not detected before the netcardconfig. I have seen one router that didn't properly do a DHCP configuration with Knoppix even though it did DHCP handshake with Windows (an old 802-11b Belkin), so it certainly can happen that a router doesn't DHCP handshake properly and cause a problem, but so far I don't have enough information to say if that is happening in this case, or even if you equipment is trying to do a DHCP handshake.

....Btw my hard drives (as probably you may have assumed) are formatted as NTFS, which as advised by most linux distros i have, is not fully compatible with linux but just experimental.

Knoppix can read NTFS partitions just fine and can work fine on systems with them or even on systems with no hard disk at all. Writing data to NTFS partitions has been a problem for Linux that has had many bad results. Frequently when someone managed to do it at all the partition would become corrupted. Sometimes this was immidately evident, sometimes it would fester for a while and come back to haunt you later. Some previous attempts to write to NTFS were removed from Knoppix because they had been abandoned. The claim was made with version 5.x that in some cases you could now write to NTFS. That "in some cases" qualification scarred the heck out of me, and I decided not to risk my hard disk to it. And I don't think there is a good reason for others to risk it either. I've seen a few people post that they were able to get it to work, but never with any detailed technical data or history of use of the drive that would convince me that it presented long term safety for the partition. And even then I'm not convinced that Microsoft, sworn emeny of Linux, might not do something in a "security update" that might deliberately destroy the partition if they detect that it was written to by Linux in the future. Heck, we see plenty of reports that NTFS has been corrupted by XP itself, that's what brings many people tio Knoppix looking for data recovery, and now there are reports that Microsoft acknowledges it's own software can't write to NTFS safely, so why expect Knoppix to be able to do so? If you want to risk your data to NTFS partitions and Knoppix, be my guest, but I'll not do it nor advise others to risk their data.

I think there was a misunderstanding.
I am using static IPs (if i'm correct that's exactly the opposite of DHCP).
So that is why i have to configure my
IP address to 192.168.2.101
Netmask 255.255.255.0
Broadcast 192.168.2.255 - works now
Gateway 192.168.2.1
always. i.e. I need them to stay like that .
I think once i had found a command to display all the hardware configuration - if you can tell it to me it's better but i might find it again.
I didn't quite understand what you meant by NIC but i'm using ASRock motherboard 939A8X-M with
Ali/Uli M5263 ethernet .
I will try checking if knoppix is configuring the right driver for it.
The problem you mentioned about the gateway was in fact about the broadcast. I didn't know what to put there and while doing netcardconfig i mistyped and put 192.168.0.255 instead of 192.168.2.255. I think that 192.168.2.255 is good, right?
About NTFS : is there any safe way to share data between linux and windows (until i get everything running ok)?
Please confirm that my IP settings look fine now.
And also if you can, give me some commands that will give you the answers you need.

I hope this gives you enough info.

According to windows XP the ethernet card should show Uli 5263.
I tried finding a driver for it but the only one i found needs something called tulip which i don't have in knoppix.
Any ideas?

[Harry Kuhman]

I'm not even clear what the current problem is. You wrote:

I finally managed to fix it...by mistake! All my IPs start with 192.168.2.xxx
I set my Bcast address to 192.168.0.255 and it worked ! I'm happy with this but for future .....

So the Broadcast address made no sense, but at least you seemed to think it was working. So you clearly have the NIC (network Interface) drivers in Knoppix. Then you wrote:

So I reconfigured the (this is the first time i'm using knoppix to write on this site, i don't know why some words are being written in red ! anyway....) eth0 broadcast to 192.168.2.255 and it works too . I also think that this is better.....

Even better. You connected with a meaningful broadcast address (which should help your local network work better). Things are clearly working, you said that you posted the above from within Knoppix.

I'm not sure why you need to use a static IP address, but it's certainly a valid thing to do. There can be some reasons to do this, such as running a server that needs to always be on the same IP address. Some routers are very good about letting you lock a MAC address to an IP address, but others often give out different IP addresses every time that the computer connects, making DHCP a problem for servers. But you seem to be able to configure the system adequately by netcardconfig by bypassing DHCP and setting a static IP address (I wouldn't exactly use the term opposites, but these are two different ways to assign IP addresses, DHCP lets the router hand out available IP addresses and related information like the name server, network mask, gateway and DNS server, while bypassing DHCP lets you set these parameters manually).

So what is the current problem?

[archimedes1981]

the current problem is that it hangs whenever it feels like i.e. erratically :- without me doing the same things at the time that it hangs.
i figured out that the ethernet driver is incorrect and maybe that's why it's hanging.
I found a driver for it but it needs something called tulip which i don't think i have and besides that it tells me to look for folders which i don't definitely have.
Can it be the ethernet card driver that hangs the complete system, it's Ali/Uli M5263.
If yes how can i install the driver ?
Or if it's NOT the incorrect ethernet card driver that hangs the system, how can i find what it is?
