OK, I downloaded and installed netcat and run the command: $ echo xymondboard | netcat 193.61.54.144 1984
waited for a couple of seconds but nothing was returned. I tried both 'netcat' and 'nc'.
I then killed all xymond jobs: $ killall -9 xymond
then run your netstat command: $ netstat -na|grep 1984.*LISTEN
and it returned:
$ tcp 0 0 0.0.0.0:1984 0.0.0.0:* LISTEN
xymond is not anymore in my 'top' list.
$ps auf | grep xymond
returns:
$ xymon 1465 0.0 0.0 4012 664 pts/1 S+ 14:35 0:00 \_ grep xymond
also xymon.sh is running
I am getting confused and the reason is that although I think I killed xymond now xymon seems to be working and the hosts.cfg file gets loaded. I removed and added a few hosts and the main xymon page gets updated now.
However my xymond is not happy because it's posting a yellow dizzy face.
Please see a few lines from xymonlaunch.log:
2012-10-16 11:07:41 FATAL: xymond sees clientcount 1, should be 0. Check for hanging xymond_channel processes or stale semaphores

2012-10-16 11:07:47 Setting up xymond channels

So why everything works after I killed all xymond???
I am super-confused.

It seems that telnet works because it returns "connected to
193.61.54.144", however it looks like it hangs after the:

That's to be expected. When doing a telnet test like this, you can get one of three things:
* connection refused (nothing listening on that port)
* time-out (firewall dropping packets)
* connected (works)
You got the last one, so all good.
If you have netcat, try doing this:
$ echo xymondboard | netcat 193.61.54.144 1984
This should get you a list of hosts and their status. The command might be "nc" rather than "netcat".

Perhaps you have xymond running twice? Stop xymond, and kill all remaining xymond processes before attempting to start it again. Before starting, you should see no output from this:
$ netstat -na|grep 1984.*LISTEN
