Ports table

The table doesn't include dgram and streams (e.g. socket files).

If you start a new service or want to make reservations for a port or a port range for occasional services (e.g. a range of ports for DCC transfers on a IRC bot or client), indicate them here.

If you wish to check the table is accurate, sockstat | grep "*:" could be helpful.

Troubleshoot

php-fpm service has been modified by php package

After a pkg upgrade, the php package will overwrite the /usr/local/etc/rc.d/php-fpm file. As PID files path change between their version and ours, you can't reload the php-fpm services anymore.

To solve this issue, call Salt to restore the amended multi instances services: salt-call --local state.apply roles/webserver-legacy/php-sites/php-fpm.

To avoid this issue in the future, you can also amend the Salt state to provide a new service name, and replace php-fpm by a message inviting to use the new one.

A service can't connect to MySQL "localhost"

MySQL library hardcodes the default socket path.

We provide the correct path at /usr/local/etc/my.cnf and in php.ini configuration, but some services, like TCL fbsql, don't read the my.cnf file and don't offer alternative configuration.

In such case, use 127.0.0.1 to connect to MySQL.
