Problem Description:
inetd refuses to accept more than 40 connects per minute on a 
particular socket (loop detection) 

The SS1 is fast enough, that you can end up legitimately calling 
rsh more than 40 times per minute.

This patch adds a new argument, "-r", to inetd that allows you to 
specify number of connections allowed in the given time in seconds.
The default is to allow 40 connections in a 60 second period, E.G:

/usr/etc/inetd -r 40 60

Typically for a faster machine you might up this to 60 connections 
per minute, E.G:

/usr/etc/inetd -r 60 60

You will need to edit /etc/rc to make the change permanent each 
time the machine is rebooted, E.G:
...
...
if [ -f /usr/etc/inetd ]; then
        inetd -r 60 60;                  echo -n ' inetd'
fi
...
...

INSTALL:

 As root:

# cp /usr/etc/inetd /usr/etc/inetd.FCS
# cp `arch -k`/{4.0.3,4.1,4.1.1,4.1.2,4.1.3,4.1_PSR_A}/inetd /usr/etc/inetd
# chmod 755 /usr/etc/inetd

At this point you will need to reboot your system by either doing
a halt; reboot; or shutdown and reboot.
