Technical Details

what runs on :55000

The IANA service-name registry assigns TCP port 55000 to fcp-addr-srvr1. The assignment identifies the service and transport, but I cannot establish a widely implemented handshake, framing format, or default deployment behavior from that assignment alone.

security overview

This is a specialized service and would not normally need to be reachable from the public internet. An exposed listener may disclose or provide access to Fibre Channel-related infrastructure; restrict it to trusted networks and do not assume the traffic is encrypted.
