Hi Jeremy I haven’t pointed any clients to the xymon server as yet. The local xymon-client service is disabled and not running. The xymonclient is configured in the tasks.cfg, I did disable xymonclient but did not solve the problem. The server where im struggling is is 24.04.1 LTS (Noble Numbat) Best regards ChrisP From: Jeremy Laidman <jeremy@laidman.org> Sent: Saturday, 14 September 2024 03:17 To: Xymon mailinglist <xymon@xymon.com>; Chris Pretorius <chris.pretorius@coaxle.co.za> Subject: Re: [Xymon] Re: Xymon on Ubuntu 24.04 Chris Presumably this is a new installation, are there other hosts that have the client installed? Did you install the client package (xymon-client) onto your Xymon server (it won't monitor itself if that's not the case). The bug reporter said that it seemed to work with Ubuntu 22.04.4, but getting the errors on 22.04.1. What sub-release are you running?

If so, you may need to change it from Enforcing mode to Permissive mode in the /etc/selinux/config file. SELinux will block many of the commands run by Xymon unless they are all explicitly granted permission by SELinux.
