Obtaining data from a UDP Port

Mark Hobley

2005-12-17, 7:01 pm

I wish to use a script to obtain some data, which I hope to send via a port.

I have created an entry in /etc/inetd.conf as follows:

4001 dgram udp wait webcount /scripts/system/websys/countupd.sh countupd

My script countupd.sh is as follows:

#!/bin/sh
read MSG # presumably input from the inetd invocation is on standard input
eval "`./zapcrap.exe`" # remove bad characters from MSG
echo "$MSG" > /tmp/test.fil

Is this all that I need to do to get the data ?

I will be sending a text message to the port via netcat, when I find out how
to do this.

Mark.
