Note: /usr/sbin/in.rshd in a link to /usr/srv/bin/in.rshd.
The rshd daemon is a recent acquisition.
If your problem only is to submit a remote command to muLinux, you can
use two other mechanism:
1) the internal web server and a CGI script
2) a little netcat program.
I will describe the method 2) that require two scripts:
/usr/sbin/control and /usr/sbin/in.control.
a) create the script /usr/sbin/control
===========================================================
#!/bin/ash
while [ 1 ]
do
/usr/bin/nc -v -e /usr/sbin/in.control -l -p 99 2>>/var/log/control.log
done
===========================================================
b) create the script /usr/sbin/in.control
===========================================================
#!/sbin/ash
while [ 1 ]; do
read cmd
eval $cmd
done
===========================================================
c) run
/usr/sbin/control &
(or put in in inetd.conf)
control does run an instance of "nc", listening to tcp port 99. It exec
in.control and read every chars you send and execute it.
You can put in the main loop (in.control) a switch statement in order
to allow only a predefinite set of administrative commands.
This is the simple model used in other rustic daemon, such pygmy web
server, etc.
