NAME¶

semanage-port - SELinux Policy Management port mapping tool

SYNOPSIS¶

semanage port [-h] [-n] [-N] [-S STORE] [ --add -t TYPE -p PROTOCOL -r RANGE port_name | port_range | --delete -p PROTOCOL port_name | port_range | --deleteall | --extract | --list [-C] | --modify -t TYPE -p PROTOCOL -r RANGE port_name | port_range ]

DESCRIPTION¶

semanage is used to configure certain elements of SELinux policy without requiring modification to or recompilation from policy sources. semanage port controls the port number to port type definitions.

Default port definitions are contained in policy modules and can't be removed without removing corresponding module. Therefore semanage port uses so called local definitions, which are assigned higher priority and override default definitions for the same port.

semanage port -l lists all port definitions (both default and local) which can result in seemingly conflicting or duplicate entries. Use semanage port -l -C to only list local definitions.

-l, --list

List records of the specified object type

-E, --extract

Extract customizable commands, for use within a transaction

-D, --deleteall

Remove all local customizations

-t TYPE, --type TYPE

SELinux type for the object

-r RANGE, --range RANGE

MLS/MCS Security Range (MLS/MCS Systems only) SELinux Range for SELinux login mapping defaults to the SELinux user record range. SELinux Range for SELinux user defaults to s0.

-p PROTO, --proto PROTO

Protocol for the specified port (tcp|udp) or internet protocol version for the specified node (ipv4|ipv6).
