Hi

I received this e-mail from Gyrniff <frohn () superbruger dk>:

*** start: ***
I used ethereal to sniff a connection and looked at the SYN-ACK packet. 
This 
SYN-ACK did no look like any SYN-ACK packets I ever have looked at (and I 
have looked at a few, I'm working on making a TCP fingerprint better than 
nmap ;-)) so I just wonder if your cabel modem died on the first SYN-ACK 
or 
did you resive any of the html content too ? 

My theory is, that it could be a malfunction in the TCP-stack, I don't 
think the html content contains any thread. 
*** end ***

To help him and others to figure out what is going on I used ethereal to 
capture all packets and print them out to 3 textfiles ( summary, detail 
and hex data ). I have compressed the files into a zipfile which can be 
downloaded via this link:

skybuck.soshost.net/VanDaleCrash.zip

Anyone that is interested can freely download it :)

Please dont use it to nuke me or stuff like that :)

To bad www.vandale.nl does not work on my cable modem... I used it 
regularly to search for the meaning of dutch words. It's a very well known 
dutch dictionary called 'Van Dale'. The online version is just a tiny 
version.
