Normally, Centreon installation need an Internet Access just after the installation to update RPM package, check the license or download Plugin Pack.

Unfortunately, High secured supervision platforms can have restricted or forbidden Internet Access (even with a proxy)

It will be interesting to create an Air gap procedure to install, update et maintain this kind of configuration.

Right now, creating a private rpm repo is not a problem with an FTP/HTTP server, but the license check and PP download could be tricky.

Is there any clue about this?
