can not conect to linksys router

**ranmaaaron** · 10-14-2006, 05:36 AM

did the ping test this time from the dell after powercycling the router and shuting down all computer and still got this for the ping

Code:

knoppix@1[knoppix]$ ping -c5 192.168.1.1

will test the the network card config again on the dell now after restart.

doing what i did before with the net card config i got the same thing this time with the dell. i get this

Code:

knoppix@1[knoppix]$ ifconfig
eth0      Link encap:Ethernet  HWaddr 00:80:AD:77:F8:7C
          inet addr:192.168.1.101  Bcast:192.168.1.255  Mask:255.255.255.0
          inet6 addr: fe80::280:adff:fe77:f87c/64 Scope:Link

          RX bytes:700 (700.0 b)  TX bytes:700 (700.0 b)

knoppix@1[knoppix]$

then the failed message from the dhcp broadcast and ifconfig give me this

Code:

knoppix@1[knoppix]$ ifconfig
lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0

knoppix@1[knoppix]$

it seem the knoppix does not like my networkcards because if i conect direct to the router i can conect for about one webpage then if i do an ifconfig i drops my eth0 for some reason if any knows why this is and how to bypass it it would be great if there is none then thanks all for your help.

No, I don't believe that's it, I'm using a CNET PRO200WC PCI FastEthernet Adapter and have no problems with it. Of course, card makers are famous for slip-streaming different chipsets into cards so I can't say with 100% certainty that it's not your NICs, but to see this with two different brand of NICs, both presumably simple 10/100 basic NICs, makes this extremely unlikely to be the issue.

I'm at a real loss to explain why the DHCP setup at first works though and then later you don't show an eth0 interface in ifconfig. This is completely in conflict with no only my experience but with everything else I've seem people here report about networking under Knoppix in the last three years.

is there any way to change the mac address that knoppix uses because i know that my isp will only alow one mac address out and i read in another post that it is posible but not common for knoppix to change the mac address by it self.

The MAC address is dtermined by a EEROM on the NIC, all NICs are made with a unique MAC addres. Knoppix should be using the exact same MAC address as when the same NIC is used under windows. There was one report a couple of years ago where this was said to not happen, but I've never seen it fail to work properly myself, particularly on my CNet NIC.

To answer your question, yes, Linux (and Knoppix) can tell the stack to use a different MAC address than what is assigned to the NIC by the EEROM. I'm not sure of the exact command to use to do it though, but you should be able to find it with a little searching on Google faster than waiting for someone to give it to you here.

But if, as I have speculated, there is a router built into your modem, then the ISP only sees the MAC address of the router, not of any of your computers. MAC addresses are not routable across the Internet, they apply only to the local network and are stopped at the first router. If you have determined that the modem does not include a router then something really nasty is going on. Maybe you ISP is doing NAT on his end and giving you a non-routable IP address. That would not be good, it would greatly limit what you could do with your Internet connection. But it really doesn't look like that is happening in your case.

Update Ok I finaly got the time to download knoppix 4.0.2 i am able to conect to the internet and my router with this verson i have no idea what would make a diference but obvisly some thing is diffrent some one may want to look in to this. i am fine for now using the older verson as it works about the same.

**Ironfighter** · 11-01-2006, 10:31 AM

It seems I am having the same problem as you (see me post of a couple of days ago) - same symptons exactly. I can reach the internet from Knoppix 4.0.2 Live CD but not from Knoppix 5.0.1 Live DVD. Doesn't it bug you?
