I've run mkpasswd and mkgroups, installed sshd, run sshd-host-config, turned on privilege separation, installed it as a service. 'CYGWIN sshd' service starts normally but it closes connection right after successful login: """ $ ssh localhost user AT localhost's password: Connection to localhost closed by remote host. Connection to localhost closed. """ Logged in sshd's account and started '/usr/sbin/sshd -d' and tries to login via ssh localhost. Tail of sshd output follows: """ debug1: userauth-request for user user service ssh-connection method password debug1: attempt 2 failures 1 Accepted password for user from ::1 port 63719 ssh2 debug1: monitor_child_preauth: user has been authenticated by privileged process debug1: Entering interactive session for SSH2. debug1: server_init_dispatch_20 debug1: server_input_channel_open: ctype session rchan 0 win 1048576 max 16384 debug1: input_session_request debug1: channel 0: new [server-session] debug1: session_new: session 0 debug1: session_open: channel 0 debug1: session_open: session 0: link with channel 0 debug1: server_input_channel_open: confirm session debug1: server_input_global_request: rtype no-more-sessions AT openssh DOT com want_reply 0 debug1: server_input_channel_req: channel 0 request pty-req reply 1 debug1: session_by_channel: session 0 channel 0 debug1: session_input_channel_req: session 0 req pty-req debug1: Allocating pty. debug1: session_pty_req: session 0 alloc /dev/tty2 chown(/dev/tty2, 11135, 10513) failed: Bad file descriptor debug1: do_cleanup debug1: session_pty_cleanup: session 0 release /dev/tty2 """ It conflicts with mintty because every mintty allocates terminal for himself like this running in mintty: """ $ ls -l `tty` crw--w---- 1 user Domain Users 136, 0 Aug 1 18:46 /dev/tty0 """ Version: CYGWIN_NT-6.1-WOW64 1.7.9(0.237/5/3) 2011-03-29 10:10 i686 Cygwin -- Regards, Alexey. -- 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
