[NCLUG] Debian 3.1 and rsh/rlogin

[Dave Treece]

Well,

   I had to add pam_securetty.so to the pam.d/rsh and that got me to where I
can at least remsh/rsh into the box and run commands, login still asks for a
password though, I guess I can at least work with that.

  Securety is nice, but it sure makes it tough to do things without
passwords these days. There's got to be a nice medium for a network of
systems isolated from the rest of the world.

 The "+ user" syntax has proven to be not entirely reliable across
architectures and version lifespans, so much so that we don't even use it
here or rely on it ever working outside of NIS environments. You do need
to populate the hosts.equiv file with your hostnames, possibly with both
short and long hostnames, in order for the simple rsh/rlogin commands to
work.

 We run this across Solaris, HP-UX and RHEL Linux and rsh is happy enough.
