Many operating systems require special treatment when an application wants to bind (listen for incoming data) on a "privileged" port (a port number under 1024).

There are various methods to deal with this.

Does install4j provide functionality that allows the installed (server) application to bind to privileged ports on platforms where this is applicable?

install4j has no special functionality for that purpose, you would have to run the launcher as root.

  • Running the launcher as root causes the application to be installed and ran as root? Although that might be a workaround for some, I severely dislike running my (server)applications with root privileges. Could adding Linux Capabilities (or equivalent) be added to the roadmap, if feasible? – Guus Jul 03 '18 at 12:59

    install4j launchers do not use native code on Linux/Unix, the launcher is a shell script. So if you need a native dependency for this feature, you would have to provide it separately. – Ingo Kegel Jul 03 '18 at 15:02
