sshd was stopped while that run because it did not login anyway. and still
don't.
sshd will run even if you're having problems connecting to it. I'm just
making sure that you are testing with a running server. If not, then
you want to make sure the server is running first.
Yes, it's running. Now it is set up as a service with automatic start up.
The messages
>>> 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
were got running sshd -d in console.
I was suggesting that you run sshd with all the debug flags
(i.e. "-d -d -d") to see if you'd get more useful information
about your problem.
I've run it with -ddd. There is nothing new around the tty allocation.
The full output is attached. May be it can give some clue.
Thank you :)
