ps ax | grep inetd

If running inetd, check for the existence of the file named /etc/inetd.conf. If it is there, edit the file /etc/inetd.conf. Look for a line that looks like:

"# shell stream tcp nowait root /usr/sbin/rshd "

Uncomment that line, save the change. Type the command

kill -1 {process id that is running inetd}

then try your remote access.

If your system uses xinetd:

Edit /etc/xinetd.conf, see if it contains "disabled = shell". If so, comment it out using a #, then

kill -1 {process that is running xinetd}

see if it works. If so, stop.

Otherwise, continue with the steps below.

Change directory to /etc/xinetd.d. If it doesn't exist, then you're probably not running xinetd.

Check for a file called "shell". If it exists, edit it and make sure to change any of the following:

disable = yes to disable = no

or

enable = no to enable = yes

If the file does not exist, then you must create it by copying one of the other files in that directory, and editing it to look something like:

service shell

{
socket_type = stream
protocol = tcp
wait = yes
server = /usr/bin/rshd
disable = no
}

The "server" line may need to be altered based on your system. It will be "rshd", "in.rshd", and may be in a different directory.

Ether way, kill -1 {process that is running xinetd} and see if you can establish communication.
