Known IP Ports

The following non-standard IP ports are used by GSI Services.

All Programs should be capable to use a different port without a recompile (config file, command line flag)

General Information about port reservation . A nicer list can be found at

The original thought was that private (non-offical ports) are in the range 49152 through 65535. (resulted in using some ports as indicated below). Problem is that clients connecting to services need to use an outgoing port. These ports are called Ephemeral Ports. Linux is by default using the range 32768 to 61000. Nothing bad happens if also a listener/service is in this range but it should be avoided.

Ports below 1024 are privileged ports. They should not be used by user applications as they require root privileges to open a bind.

The table lists knows listeners/services (not ephemeral ports). Ports should only be reserverd after consulting BEL/IN.
