Internet-Security.com TCP port 11300 details

TCP port 11300 is the default listen port for beanstalkd, a simple, fast work-queue/job queue server (IANA-registered as “beanstalkd”).
Frameworks and apps that use beanstalkd connect on 11300, for example Laravel’s beanstalkd queue driver (via the Pheanstalk PHP client) defaults to 127.0.0.1:11300.
Common production clients that talk to 11300 include Pheanstalk (PHP), beanstalkc (Python), and beanstalkd-client (Ruby) to enqueue/dequeue background jobs.
Containerized deployments (e.g., the schickling/beanstalkd Docker image and community Helm charts) expose TCP 11300 for the beanstalkd service.
