Re: How can I configure ssh preprocessor??

Carlo,

   I have a big problem with the ssh preprocessor configuration when
"enable_protomismatch" is enabled. I have several different unix
platforms on my network, like Solaris, OpenSolaris, RHEL, Ubuntu, etc.
With my actual ssh preprocessor configuration, a lot of alerts are fired
because every platform shows a different string.

I had a similar issue here (2.9.0.4, OpenBSD).  Google suggested 
removing "autodetect" from the ssh preproc config, this worked for me 
even with "enable_protomismatch" enabled.

BTW, the most obvious fix would be to remove "enable_protomismatch", no?


ciao,
Olaf
