How to start and stop Firebird Classic on Mac OSX?

To start, use:

sudo launchctl load /Library/LaunchDaemons/org.firebird.gds.plist

To stop, use:

sudo launchctl unload /Library/LaunchDaemons/org.firebird.gds.plist

telnet localhost 3050

When Firebird is running, the output would contain:

Connected to localhost.

To ensure that Firebird is running on port 3050 (and not some other server), you can run the following command (in another Terminal) while the Telnet is waiting for your input:

ps ax | grep fb_inet_server

It should contain:


These commands were tested on MacOS 10.9 Mavericks and 10.10 Yosemite with Firebird 2.5 Classic server, but should work on all versions.
