Hello,
I have just discoverd that ssh -T does not work with servers which have
UseLogin option enabled. This happends becouse /bin/login can not work if
there is no tty. To correct this, it is necessary to add:
options.use_login = 0;
at the top of the "do_exec_no_pty" function from the
"session.c" file.
Best regards,
Krzysztof Oledzki
