Maybe somebody can help here, my problem gets me nuts.
I go to a friend who has cable modem (and an ipv4to6 tunnel). I have never had cable modem so I'm a bit lost. Maybe somebody who has cable link can help me.
He has XP and he gets his adress by DHCP.
I tried to replace it with my laptop running debian.
When starting the dhcp client and a network analyzer, the only thing I see is:
dhcp discover from 0.0.0.0 (me) to 255.255.255.255 id X
lots of arp who has (broadcast) <- that's cable yes
dhcp offer from 220.127.116.11 (cisco) id Y <-- some people get an offer
dhcp ack from 18.104.22.168 (cisco) id Y <-- and they really get an IP
Unfortunatly never an answer with id X so my dhclient never gets anything.
I tried tweaking all the obscure timeouts of dhcp but no way, the damned thing doesn't like me.
Next I started FC7 live and same thing (appart from the fact that fc7 tells me oh yeah you're connected while in fact I'm not.. wrong information)
I also started the XP again and released the lease, thinking the dhcpserver doesn't want to assign another one while one is still attributed (?)
ipconfig/all then shows that everything is released.
Plugged the debian again, nothing.
Plugged the fc7 again, nothing.
Geeettts me nuts. Even more when my friend looks at me and says:
"See, I plug my xp and I have nothing to do, it just works"
Could it be that my dhcp frames contain wrong info?
Maybe I should install a sniffer on his xp and compare my frame?
Or something wrong with the 4to6 tunnel (I am a bit in the dark with ipv6)?
I have no firewall btw.
Any idea or experience very welcome!
