I managed to solve the problem on my own. I simply disabled SELinux by editing "/etc/selinux/config" file, replacing "SELINUX=enforcing" with "SELINUX=permissive", and then I rebooted the computer. Now everything works fine.

Thank you for your help !

In my case, the user is "apache". I added it to the groups "xymon" and "root" that own the Xymon's folders, but this didn't change anything.

This sounds familiar. I think this may involve the web server process owner having access to the xymon files. I'm assuming you are using apache, run:

ps -elf | grep apache

This will show you something like:

5 S wwwrun 23599 23582 0 80 0 - 21785 inet_c 15:17 ? 00:00:00 /usr/sbin/httpd2-prefork -f /etc/apache2/httpd.conf -D SYSTEMD -DFOREGROUND -k start

In this case the user/owner is "wwwrun". From memory, redhat/centos uses "www". Once you know who is running your web server, you can then check the ownership of the xymon data files to see whether the above user has access. The web server "owner" needs to be able to access these files and the xymon cgi scripts.

hope that helps.

cheers, Phil

I don't fully understand what you mean. How do I check that the username running the Xymon server is allowed to "log into the client" ? (and if it can't, how am I suppose to allow it ?)

Concerning the Xymon server icons, I may have not be clear enough: For now, the only monitored system is the Xymon server itself (the client is launched on the same machine as the server). Thus the only icons I have are the ones that corresponds to the server itself. However I just remarked that some of them are working or having a different problem. Below is a quick overview:

• bbd, conn, cpu, disk, files, http, inode, memory, msgs, ports, procs, trends, xymond, xymonnet, xymongen are returning the "cannot load host configuration" error;
• clientlog is returning another error : "status not available: Req=clientlog localhost.localdomain, result=5". In the httpd error log file, the same lines appear;
• info seems to work. The row "alerting" however says "alert configuration unavailable but I suppose this is a different problem.

Thanks for your help !

Almost looks like a simple user validation proble.

Check the username running the Xymon server is allowed/able to actually log into the client.

Is are the Xymon server icons behaving the same way?

Indeed, 'ipaddress' corresponds to the server's IP address and 'clientipaddress' is the IP address of the computer I use (the server is on a Linux computer but I use a Windows one to work).

Have you substituted your IP addresses in the logs with “ipaddress”?

Hello,

I've recently installed Xymon (version 4.3.27 on CentOS 7) and the http://ipaddress/xymon/ page is working properly.

However, when I click on any of the icons, I get a "Cannot load host configuration" error. One minute later, the page is redirected to another one : http://ipaddress/xymon-cgi/30. There I get an error 404.

I also have errors in httpd logs file :

For the error 404, I get this line :
