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.

       -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|dccp|sctp) or
              internet protocol version for the specified node
              (ipv4|ipv6).

EXAMPLE

       List all port definitions
       # semanage port -l
       Allow Apache to listen on tcp port 81 (i.e. assign tcp port 81 label http_port_t, which apache is allowed to listen on)
       # semanage port -a -t http_port_t -p tcp 81
       Allow sshd to listen on tcp port 8991 (i.e. assign tcp port 8991 label ssh_port_t, which sshd is allowed to listen on)
       # semanage port -a -t ssh_port_t -p tcp 8991
