+#### side note: openssh 5.6
+
+It used to be that the gitolite documentation would say "just use `ssh
+git@server`" in the past, because gitolite defaults to the "info" command if
+no command is passed.
+
+However, starting with [openssh 5.6][openssh56], this won't work. Openssh
+will now "Kill channel when pty allocation requests fail". This means that
+gitolite is not even invoked; you only get a message about pty allocation
+failure, followed by "connection closed".
+
+So now you have to use an explicit "info" command, (`ssh git@server info`) or
+add the `-T` option to ssh (`ssh -T git@server`).
