Re: [Expectperl-discuss] ssh works from console but not once daemonized

[Ed A. <er...@uc...>]

I gathered from your explanation that your expect-perl program
wasn't working in daemon mode because it expects to have a
controlling tty (i.e. "/dev/tty") to write to.  I'm assuming
that you're running in daemon mode such that your controlling
tty is undefined; i.e. if you did a "ps -ef" (or whatever's
appropriate for your system), the "TTY" columns for your
daemon process would contain '?'.

So maybe (and this is iffy, given the weird things ssh does
under the covers) if you move the unusable /dev/tty
out of the way and create /dev/tty as an ordinary file your
program can write to, things will work.

Unfortunately this will require root permission, since
/dev/tty is root-owned (at least on Redhat and Solaris).
