Subject: last patch is too much drastic?
From: Marco Palumbi <marco.palumbi,AT,bigfoot,DOT,com>

Its only few days I am using CIPE.
It seems to me that the patch cut out some part of the protocol(CT_PING
??).
With CIPE patched i also experience some more problems having the two
system connected.
Here are the daemon debug output and syslog on the linux box for both
CIPE 1.5.2 with and without the last patch. (crasher [IMPORTANT PATCH])

My system:
