Bug#381262: linux-image-2.6.17-1-686: TCP bug introduced in 2.6.17
Package: linux-image-2.6.17-1-686
Version: 2.6.17-4
Severity: important
It is impossible to access the following URL using kernel 2.6.17:
http://icfp06.cs.uchicago.edu/
No data seems to be received, when running Debian's kernel 2.6.17, using any web brower (Konqueror, Firefox...), or even using telnet:
telnet icfp06.cs.uchicago.edu 80
GET / HTTP/1.1
host: icfp06.cs.uchicago.edu
This problem occurs always and only with that web site (I have found no other site that triggers that problem), and only when using kernel 2.6.17.
It must be noted that this problem disappears when running a previous kernel version (I re-tried running at least version 2.6.16 on the same Debian system).
This is not a problem tied to our network configuration: all other users of our network can access that URL without problem, using any other OS.
This is not a hardware problem: when running kernel 2.6.16 or Windows XP on the same hardware, I have no problem.
Running ethereal, I observed that the HTTP TCP data is actually received, but seems dropped by the kernel before being delivered to the client process (browser or telnet).
If you can't reproduce that problem, please tell me what additional information you would need.
