semanage-port - Man Page

• List all port labeling rules: sudo semanage port -l|--list
• List all user-defined port labeling rules without headings: sudo semanage port -l|--list -C|--locallist -n|--noheading
• Add a user-defined rule that assigns a label to a protocol-port pair: sudo semanage port -a|--add -t|--type ssh_port_t -p|--proto tcp 22000
• Delete a user-defined rule using its protocol-port pair: sudo semanage port -d|--delete -p|--proto udp 11940

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.

-h,  --help

Show this help message and exit

-n,  --noheading

Do not print heading when listing the specified object type

-N,  --noreload

Do not reload policy after commit

-S STORE, --store STORE

Select an alternate SELinux Policy Store to manage

-C,  --locallist

List local customizations

-a,  --add

Add a record of the specified object type

-d,  --delete

Delete a record of the specified object type

-m,  --modify

Modify a record of the specified object type

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

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
