Ok, I will
not waste my time to argue over obvious things. You won't get ports more "default" than from this list. Protocols, ports and service names are registered for a reason. Ex: If you install MySQL server it will be configured to listen on port 3306\tcp by default on any OS, be it Debian, RHEL, or Windows. On 01.10.2017 06:40, Victor Porton

Assuring that my port is not in this IANA list is not enough to ensure that my port number will not clash with a port number used by a Debian package (by default). So your answer to my question is wrong.On 01.10.2017 06:04, Victor Porton wrote:We are going to install a range of software on a Debian Linux installation. Because we run the same software (such as Celery) several times, we need to use port numbers different than the standard Debian port numbers chosen by default (because we can't run more than one instance of a server with the same port, and thus using the standard port number for all servers would fail). How to choose TCP/IP port numbers for server software we run in such a way that they don't clash with "standard" Debian port numbers? In Debian are there any ranges of port numbers dedicated (so that they wouldn't clash with "standard" that is used by default port numbers) for servers configured by users? Note that we run (at least some of) our software not as root, so we can't use ports below 1024. |
