Note: Even if ''inetd'' is not running, it is a good idea to comment out ''r'' services in ''inetd.conf'' in case ''inetd'' is ever inadvertently started.

Are any ''r'' services enabled in ''inetd.conf''?
$ '''egrep '^shell|^exec|^login' /etc/inet/inetd.conf'''
shell stream tcp nowait root /usr/sbin/in.rshd in.rshd
shell stream tcp6 nowait root /usr/sbin/in.rshd in.rshd
login stream tcp6 nowait root /usr/sbin/in.rlogind in.rlogind
exec stream tcp nowait root /usr/sbin/in.rexecd in.rexecd
exec stream tcp6 nowait root /usr/sbin/in.rexecd in.rexecd

If so, disable the ''r'' services in ''inetd.conf''. The version of ''perl'' on this system does not support the ''-i'' flag.
# '''perl -pe 's/^shell/#shell/;s/^login/#login/;s/^exec/#exec/' /etc/inet/inetd.conf > /etc/inet/inetd.conf.new'''
# '''mv /etc/inet/inetd.conf.new /etc/inet/inetd.conf'''
# '''chmod 444 /etc/inet/inetd.conf'''
# '''chown root:sys /etc/inet/inetd.conf'''

Send ''inetd'' a SIGHUP for the changes to take effect.
# '''pkill -HUP inetd'''
