openssh unix dev - Apr 2002 - SSH client, dup, pty.

Hey,

	I am hoping that some one on this list may be able to help me.

I started investigate the possibility of forking a process, the child then 
attach to a pty, dup std[in|out] to the pty, then exec the ssh client.

For some reason, the ssh client still prompted straight to stdin and 
stdout rather than through the pty that I created. 

There seem to be a few issues with this. Can someone tell me if it is 
possible to achieve this set up before I spend to much time on it. 


Thanks

You probably haven't set the controlling terminal, have a look at 
Stevens _Advanced Programming in the Unix Environment_ or 
sshpty.c:pty_make_controlling_tty() for how to do this across common 
platforms.
