I don't understand how this conflicts with mintty. mintty should allocate the first tty if it is the first thing run. ssh would allocate some other pty (tty2) after that. I don't see anything amiss other than the error message above. We'll need to see the debugging details mentioned here: http://cygwin.com/problems.html Please provide information on any changes you've made to your ssh setup as well as the cygcheck output mentioned there. cgf -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
