Hi,
Try these cases.

 /usr/sbin/in.rlogind should have permissions 555 and own bye root :staff.

-r-xr-xr-x  1 root     staff       16384 Jan 20  1994 /usr/sbin/in.rlogind

following entry should be in /etc/inetd.conf

login        stream  tcp     nowait  root    /usr/sbin/in.rlogind
in.rlogind

/Gayantha
