If you want a "command prompt" on the other end, why not
just run sshd or telnetd on your favorite port on the "other end" ?

Now, if you want nc to tunnel over SSH, that can be arranged too.
You need to connect using ssh to the other end and setup port
forwarding within SSH which can be used by nc to do whatever
you want to.

Subject: Netcat (NC) Secure Remote Connections via authenication

Hi All
  
Does anyone know how to set-up a secure remote connection using
netcat, in that one which uses authenication or port filtering
(without the need to install any other wrapper software).
  
I have a requirement were I need to connect to a remote machine and
get a command prompt. We all know how to do this via netcat by
setting up a listening port. My concern is that I do not want to
leave the port open for anyone to connect.
  
It would be great if when someone connects authenication is required,
hence in effect all I need is to connect to a remote machine, get
prompted for a password and then get a command prompt, if netcat
cannot do this, does anyone know any other peice of software (not
NetBIOS or SMB)?
  
Thanks
