Hello, As a guy who's built his own distro up from source code, this seems pretty straight forward to me. If you want a password-less "single user" local login, then try replacing the /sbin/mingetty entries in /etc/inittab with /bin/sh That will leave you with root shells on each of the console ttys. Alternatively, you can spawn a shell on a tty directly from your init binary (my embedded distro doesn't have an inittab; but your Redhat distros will). If you want a password-less "single user" remote login, then you'll need to get a copy of Netcat that supports command execution (the "-e" option) and set yourself up a script that says something like; nc -l -p 23 -e /bin/sh -d Optionally this could be tweaked to work out of /etc/inetd.d/something (if you run an inetd) ... YMMV However you deploy it, make sure it respawns or you'll only every get one user on. For what its worth, once you have more that one user in your environment, you want to have security; no matter how isolated those 2+ users are. ----- Original Message ----- >From: "Stephen Goggin" <sgoggin@xxxxxxxxxxxxx> >To: "Pluggable Authentication Modules" <pam-list@xxxxxxxxxx> >Subject: RE: How do I...? >Date: Tue, 30 Oct 2007 21:09:23 -0500 > > Because our software team's code has only been guaranteed on those 3 OS' > > > > > > Stephen Goggin > > Test Engineer > NetEffect, Inc. > 9211 Waterford Centre Blvd. > Austin, TX 78758 > Email: sgoggin@xxxxxxxxxxxxx > > 512.493.3232 :Desk > 512.983.1939 :Mobile > 512.493.3393 :Fax > > -----Original Message----- > From: pam-list-bounces@xxxxxxxxxx [mailto:pam-list-bounces@xxxxxxxxxx] > On Behalf Of Gary L.
