If you look up in /etc/services the ports on which rlogin/rshell are listening,
you'll see that both port numbers are < 1024. On Unix, you must be root to     
'bind' on such port numbers. This means rlogin should be mode 4755 and is no
more, probably because of the changes to the ACLs. I seem to remember that this
is a new feature at sr10.2 (i.e. sr10.1 was not "real Unix" in this respect and
did not need you to run as root to bind to port numbers < 1024).

Hope this helps,
