Whilst testing the 2.6.0-test1 kernel (I am sorry I am currently on dialup and 
have not had chance to test it on test2 yet) I experienced some very odd 
behaviour, namely entries vanishing from the list of established tcp 
connections.  Please read the attached file, if this interests you, it is just 
one transcript of the behaviour although I have experienced it several times.

I do not beleive the host has been compromised, I have compared the md5sum of 
netstat on both mine and a friends installation of Debian woody and both 
produce the same, as far as I am aware no one has developed kernel level 
malware for this version of the kernel in the form of lkms yet and the irratic 
behavour seems inconsistent of what a compromise may result in.

fd2c999a20b1e9bbb395ee8389208923  /bin/netstat
-rwxr-xr-x    1 root     root        86892 Nov 24  2001 /bin/netstat

I appologise if this is the wrong place to send such a bug, could you please 
forward it to the appropriate person.

Regards

phased
