i also have this exact same problem using
OpenSSH_3.4p1, SSH protocols 1.5/2.0, OpenSSL 0x0090603f

i start a program with "nohup <program> &" and upon
returning to my native
machine, the terminal is balnk, frozen with no bash prompt. i must kill the ssh
pid form another terminal to get my original terminal back.

thanks,
Sam

Don't do that.

Do this instead:

  (nohup <program> &)

Note the order of the '&' and the enclosing parentheses.

(nohup ./script &) is a workaround of sorts,
but that's not really a good answer.

People expect ssh to be an rsh replacement,
and rsh doesn't require a double fork
to avoid the hang-on-exit.

This thing comes up over and over again. And the same
back-and-forth arguments take place.

SSH is more than a secure RSH. It truly is. You can't have it
be two conflicting things at the same time.

Read the archives.

I believe people can learn. I really do.

[NOTE: I'm not an OpenSSH developer nor do I speak for them.]

Cheers,
