[Beowulf] passwordless rsh/ssh

It's empty (private subnet, so why not?)

/etc/hosts.allow has:

ALL: 192.168.1.0/24

rexec is yes, rsh and rlogin are no.  So I did the experiment: changed
rexec to "no" as well, restarted xinetd.  Nope  the rsh -l form
still fails.  Put rexec back the way it was.

It's an odd bug, rsh works for "fred", "sally", or "root", just not
root -> fred or sally -> fred via rsh -l, when both of those
work going to Solaris.

Anybody know where the home page for rsh-server is?  Maybe 0.17-13
is old and the current version (not available from Mandrake updates)
has this fixed?
