I have a tiny little suggestion to the developers, at least of the RPM, create the download directory. The xymon-4.3.28-1.el7.x86_64 RPM does not create it and there is no official documentation about where to create it that I could find. Anyway, for the above RPM, creating it in the xymon user's home directory works (so it will be /usr/share/xymon/download ) and means that clients can download files from there using the bb://filename URL syntax.

Kind regards,
