errors with older clients attempting to connect.
rweber errors with older clients attempting to connect.
 
I tried to debug the latest 1.19c but there seems to be a MAJOR problem with it; 1.18 Seems to work ok. Simply put, I cannot connect.
I have debugged the server up to the point where it launches a shelex process and from there the shlex process closes on me.. having difficulty trouble shooting the shelex.cpp, which just calls the session .cpp.

os's tested : windows7, server2008R2

clients tested that worked: ubuntu 12.04 OpenSSH_5.9p1 Debian-5ubuntu1.1, OpenSSL 1.0.1 14 Mar 2012, PuTTy 0.62
clients tested that didn't work: SLES 10.4 OpenSSH_5.1p1, OpenSSL 0.9.8a 11 Oct 2005, cygwin OpenSSH_5.9p1, OpenSSL 0.9.8t 18 Jan 2012

The error with the cygwin client seems to be a know issue..
ssh -o PreferredAuthentications=password -l username host
is a workaround for the issue.. Is there a place we can check code out using git and work on this project?

Internet is the more powerful tool that search for all relevant fast essay information by searching for it on different servers. They like to return result in nanosecond range. Every time, we get accurate result by typing proper query.
