PORTACL(5) File Formats Manual PORTACL(5) NAME portacl -- rc(8) script for mac_portacl(4) DESCRIPTION portacl is an rc(8) initialization script for mac_portacl(4), allowing administrators to limit or permit binding to local UDP and TCP ports that would otherwise be privileged to the superuser. Configuration is via the following rc.conf(5) variables. portacl_enable (bool) Set to "YES" to load and enable the mac_portacl(4) module upon system initialization. portacl_<users|groups> (str) A space-delimited list of user and group names or nu- meric IDs to apply mac_portacl(4) rules for, using the as- sociated portacl_<user|group>_<ident>_<tcp|udp> variables. portacl_<user|group>_<ident>_<tcp|udp> (str) A space-delimited list of service names or port num- bers to add to the mac_portacl(4) ruleset for that user or group and protocol. portacl_additional_rules (str) A comma-delimited list of raw mac_portacl(4) rules to include alongside those specified above. portacl_port_high (int) The highest port that should be considered privileged by mac_portacl(4). This corresponds to the sysctl(8) vari- able security.mac.portacl.port_high, and defaults to 1023. Note that default privileged port restrictions will not be enforced above this value. portacl_suser_exempt (bool) Allow the superuser to bind to all mac_portacl(4) protected ports. This corresponds to the sysctl(8) vari- able security.mac.portacl.suser_exempt, and defaults to YES. portacl_autoport_exempt (bool) Allow applications to use automatic binding to port 0. This corresponds to the sysctl(8) variable security.mac.portacl.autoport_exempt, and defaults to YES. FILES /etc/rc.conf /etc/rc.conf.local EXAMPLES Use service(8) and sysrc(8) to permit applications running under the "www" user to bind TCP ports http (80) and https (443). # sysrc portacl_users="www" # sysrc portacl_user_www_tcp="http https" # service portacl enable # service portacl start SEE ALSO mac_portacl(4), rc.conf(5), service(8), sysrc(8) AUTHORS Thomas Hurst.
