[WLUG] remote ssh access problem with gitolite

[Jim Irrer]

Hi -

I'm trying to move our gitolite installation, and am having a problem
getting the remote access via ssh to work.

This was actually working at one point, so there are a lot of things (ssh
keys) that I believe are set up correctly, but as the ssh log
below shows, the git server closes the connection, when it should be
listing the git repositories.

I can't be sure, but it looks like the key exchange is working, and that
gitolite is shutting down the connection, but its not
obvious why.

Full disclosure:  The client is Windows running cygwin.  It works on our
old gitolite installation.

Thanks for any insights - Jim
