To ask for the password ssh opens the controlling terminal directly.
You will need to allocate a pseudo terminal for this and make it the
controlling terminal for the ssh process. (not just std* redirection.)

Geoff,
What is happening is, when I fork off sftp, it captures my terminals
stdio, so I don't see any output in the main program. The only thing
I see is the password request, which I provide and then it doesn't
get anymore output from sftp. Sftp runs just fine but not using the
pseudo terminal.
I think I need some kind of ioctl call to stop sftp from grabing
the terminal stdio?

I think I understand what you are saying. I ran into a similar problem
trying to run xterm without tying up bash. Look up using the subsystem
keyword in the sshd config. Subsystem will allow sshd to directly spawn a
process and maintain control over it.

Subject: SSH and pyseudo tty
Hi group,
Hope this one does not get bounced.
I have written a C program that calls sftp as a child using pseudo tty
master
and slave. I can get logged into the ssh server but control of the parent
program looses control of the terminal. I know that it is ssh that is doing
the tty chances and I also know that it will work with expect. I prefer not
use expect.
Does anyone know what I need to do to fix this problem? I have searched
the
web but haven't found anything.
Hope I am making sense?
