Hi

Sorry for the confusion. I was trying to say that xymond does not load the hosts.cfg file instead of it doesn't update hosts.cfg.

Yes this IP is my xymon server. I can telnet and ssh to the server from terminal with no problems. For some strange reason the xymon main page does not get updated anymore. I have manually added a few more hosts in 'hosts.cfg' but they don't show up.

Also I have checked that

1. xymon.sh is running
2. SELINUX was disabled but iptables was not, so I have now turned iptables off as well but the problem persists. :(

I really don't know what is happening. If you have anymore suggestions please let me know.

Many thanks Yanni

2 days ago I updated xymon to the latest version:4.3.10 and for
some reason unknown to me xymond stopped updating the hosts.cfg file.

Please see xymongen.log below:

What is this server? If this is your Xymon server, then what we have here is a failure to communicate. Given that there was a timeout (rather than a rejected connection) I suspect a firewall or packet filter is dropping the packets, or perhaps a routing problem. Try to telnet to this IP address from your Xymon server, and if that doesn't work, you know it's unlikely to be a Xymon problem.

Aside from that, I'm confused. Why would Xymon modify the hosts.cfg file? Isn't that supposed to be edited by a human?

It seems that telnet works because it returns "connected to 193.61.54.144", however it looks like it hangs after the: (Escape character is '^]') line. I can type things but nothing is returned when I hit "Enter", only the cursor just goes to the next line. I only use ssh so I can't tell if my telnet works properly.

This is what I get:

telnet 193.61.54.144 1984 Trying 193.61.54.144... Connected to 193.61.54.144. Escape character is '^]'.

Yes xymond is running. It's first on my "top" list:

(23182 xymon 25 0 7992 1984 1380 R 100.0 0.1 8286:29 xymond)

The command you asked me to run returns the following:

2012-10-15 10:00:10 Using default environment file /home/xymon/server/etc/xymonserver.cfg 2012-10-15 10:00:25 Whoops !

A few more log files.

Sorry, I meant to ask if you can telnet to it on port 1984, rather than the default telnet port. So:

telnet 193.61.54.144 1984

For some strange reason the xymon main page does not get updated
anymore. I have manually added a few more hosts in 'hosts.cfg' but
they don't show up.

The Xymon page generator probably needs to query the xymond process using port 1984 (using the xymon command).

Also I have checked that
1) xymon.sh is running

Is xymond running?

Let's try to reproduce the conditions that would have led to the error message. Try running this to see what it gives you:

xymoncmd xymon 193.61.54.144 'xymondboard fields=hostname,testname,color,flags,lastchange,logtime,validtime,acktime,disabletime,sender,cookie,line1,acklist'

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
