portrelease (1) - Linux Manuals
portrelease: release previously-reserved ports
portrelease - release previously-reserved ports
- portrelease [SVC]
It is intended that portrelease is run by the initscript of the service wanting the port. For example, the cups initscript might run portrelease cups.
An exit code of zero means that a best effort attempt has been made to instruct the daemon to release the port. Non-zero exit codes mean that the daemon is running but couldn't be contacted.
