It does work; I use it.

In theory at least, using in hosts.cfg should work for you, so long as your host name is resolvable by whatever the DHCP server is giving you. For $XYMONSERVERIP, you could use and local communications would continue to work.

Ya, I finally figured it out after a couple days of beating my head against the wall.  I have Xymon running on Amazon AWS instance and if you use the AWS web interface to 'restart' the server it auto reassigns IP's, which in turn makes all my DNS settings wrong.  So I added a static IP in AWS so it shouldn't be changing anymore.  I also found the IP setting in the xymonserver.cfg file.  I also added my IP statically to the /etc/hosts file on the xymon server so I can edit at will and not rely on some DNS server out there updating it's tables.  Everything seems to be running smooth now.

Thank you.

My server got a reboot and the public IP got changed.  Now whenever I click any colored dot on my Xymon homepage it gives me this error.
Cannot load host configuration

All the suggestions I've found say that Xymon may not actually be running.  There are Start scripts in the /etc/rc#.d folders, and also I can manually start and restart it from the command line with no troubles.  What's going on?

I suspected a DNS issue but I left it overnight and it still has the same issue this morning.

Thank you.
