Getting Knoppix to recognize an thernet connection

[kwyjibo730]

The problem I'm facing is as such. My computer is wired to my Linksys Wireless-G router by ethernet cable. When I boot into Knoppix I need to run netcardconfig in order to set Knoppix to recognize the LAN (when I run ifconfig when I first start I only get stats for Local Loopback, not Ethernet). My router is enabled for DHCP but when I run a DHCP broadcast I get failed." When I answer the DHCP prompt in the negative the settings I use are as follows:

IP: 192.168.1.101
Subnet Mask: 255.255.255.0
Broadcast Address: 192.168.1.255 (I don't know what to put for this, so I leave the default)
Default Gateway: 192.168.1.1 (This is the address) I use to get my router settings
Nameserver: 167.xxx.x.203 (I forget the exact values, I can get them from the router settings, if anyone believes that makes a difference)

I once was able to get internet access, though I forget the settings I used, so there's definitely some solution to the problem. I know there's some internet functionality because when I ping the IP specified in netcardconfig, it pings succesfully, regardless of the fact that I cannot get access to web pages. Also when Knoppix boots it mentions in the output, eth0, so I believe it recognizes the ethernet connection somewhat. I think the main solution has to do with what I put into the netcardconfig settings. Would anyone know of any utils I could run or some settings that should be changed so I can get internet access.

What in the world does that mean? Pinging yourself tells you nothing. If you are trying pings, then first ping the router at 192.168.1.1 and see if you get a response from that. If that works try pinging 216.32.81.146. If that works then try pinging knoppix.net. If the second ping by IP address works and the third by URL does not then you almost certainly have a DNS issue, as they are both for the same system. We still can't tell you much about that DNS address where you hide part of it with xxx's, it might be a valid DNS server, or it might not.

Ok I've confirmed the DNS
3 are listed in my router settings
167.206.3.139
167.206.3.138
167.206.3.20
I will run those ping ASAP

So did you try the ping tests that I suggested?

[kwyjibo730]

Ok the results of the pings are as follows.
When using the gateway as 192.168.1.1 I got no reply, but on a whim I set the gateway to the default 192.168.1.255 I was able to get a response. When I pinged 216.32.81.146 I got the message

send to: Network Unreachable
wrote 216.32.81.146

When pinging knoppix.net I got an "unknown host" reply (a problem with the DNS I believe, though I have no problems of the sort in WinXP.

That's bad, the router should respond to the ping.

.... but on a whim I set the gateway to the default 192.168.1.255 I was able to get a response.

192.168.1.255 is a broadcast address (at least when using the net mask you indicated), you should not set a broadcast address as a default gateway. When you did this, what did you get a response to, a ping? Who responded? Need details, otherwise this is meaningless.

.... When I pinged 216.32.81.146 I got the message
send to: Network Unreachable
wrote 216.32.81.146

Network unreachable is a pretty strange message, if the network card is working at all and you didn't get the same message when pinging 192.168.1.1. What were the settings when this happened? Did you have that bogus 255 in place, or a more reasonable default gateway?

When pinging knoppix.net I got an "unknown host" reply (a problem with the DNS I believe, though I have no problems of the sort in WinXP.

Well yes, that one does make sense if the system can't do a DNS lookup, but with the first two failing (and failing very strangely), you have more than only a DNS problem. A DNS problem would have been indicated if the first 2 pings worked properly and then the ping that needed DNS to look up the URL failed.

Hey guys. I recently started test-driving Knoppix 5.1 live cd. So far so good. Only problem is connecting to the internet via wifi. I configured ath0 and it connects to the AP. I can see its status as connected, shows my IP GW and SM. When I fire up the browser I can't pull any websites. I did a ping and can only ping the default gateway 192.168.1.1 passed there if I try to ping I get the error message ERROR: NETWORKS IS UNREACHABLE. I'm hitting a brick wall with this. Everything seems to be configued right. I can do a scan and see all the APs on my area. Any idea????

tabo-

I was never able to solve this problem, and had it with all linux distros i tried (incl. debian, fedora core 4 and 5, and ubuntu). By and large I just gave up with Linux for now. Hope the situation works out better for you. However, the problem I had was there was no recognition of an internet connection whatsoever and no functionality (even though my netcard is hardwired to my router)

[Harry Kuhman]

kwyjibo730: I tried to help, but you never responded to my questions.

tabo: I'm pretty unreceptive to "I'm having the exact same problem" posts, particularly when the original poster can't quite define his problem. Still, I have been able to help a lot of wired eithernet users get their network connections working. You would likely be better off starting your own thread, but if you still want help post some information about your network hardware and ISP and basic information like the results of ifconfig and similar basic tests.

tabo - this is just a 'shot in the dark' until you post the results of the status revealed by:

# ifconfig ath0

Try this command:
# ifconfig ath0 mtu 1500

*Please* let us know if this is successful, and at least please post the results of ifconfig ath0
- good luck
