I receive a mail from system.

Pseudo-terminal will not be allocated because stdin is not a terminal.
Warning: remote port forwarding failed for listen port 1234

Try ssh -n (see man ssh) - this should attempt to run the command without
attempting to allocate a tty.

HTH,

I have not command to run,I just want to login remote ssh server, so I
cannot use -n. When I run "/usr/bin/ssh -R 1234:localhost:22 -l root
192.168.1.1 -n", it said:

The flag you want is -N, which prevents ssh from trying to run any
remote command at all. It's intended specifically for sessions that
are only setting up port forwarding, just like you're doing here.
