You could investigate using Big Sister as a client. It's been a few years since I used it. It ~was Perl based and ~was compatible with Big Brother/port 1984 transmission/BB messaging format at the time.

I think it is safe to mention it now; in the past, Mr. Croteau and Mr. MacGuire would throw thunderbolts from Mount BB.

Is there anyone that have made a perl module or subroutine for sending to a xymon-server without having to install the xymon client? On some node it is difficult to install a client. Some vendors are very afraid of having things installed on "their" equipment, and the os might be stripped down with no compilers and so on. For sending to xymon I guess all you need is a simple socket connections so I expect that this has been done many times already. Anyone who would like to share?

You could use xymon-rclient (on xymonton.org), where you only need an ssh connection from the server to a shell running on the client; it automagically sends the client-side script, and injects the results on the server side.

Also, this shell one-liner works on Solaris under ksh, bash and bourne shell (sh):

#!/bin/sh ( echo "$2"; sleep 1 ) | telnet $1 1984 2>&1 >/dev/null | grep -v "closed by foreign host"

Run it like this: ./xymon.sh $XYMSRV "status uname -n.testname green All OK"

Alternatively, netcat (nc) can be used like so:

echo "$2" | nc -w1 $1 1984 || echo "Connection failure"

Neither of these are ideal, because there's no way to close the connection on the client side once the message has been sent, and so it simply waits 1 second (-w1 for nc) and assumes it has all been sent.

This bash code doesn't have the same limitation. It works on Linux and should work on all UNIXes that run bash:

#!/bin/bash exec 3<>/dev/tcp/$1/1984 || exit 1 echo "status uname -n.testing green date $2" >&3

Run it as above.

This script uses the /dev/tcp bash-ism, so it's not portable to other shells. If you needed to send multiple messages in a single script, you should close the socket after each with "exec 3<>-".
