Source port varies, but destination is TCP port 0 on a wide variety of destinations. Timing varies, some are spread out, others are within the same second. Apr 23, 2020 · TCP/IP software applications use 0.0.0.0 as a programming technique to monitor network traffic across all the IP addresses currently assigned to the interfaces on that multi-homed device. A "zero-length" TCP packet merely means that the party sending it had no payload to send but needed to inform the other one about something, e.g. about successful reception of data or, vice versa, about missing data which need to be retransmitted.

Thermal device circuit breaker - TCP 0,5A - 0712152 Thermal miniature circuit breaker, pluggable in screw-type fuse terminal block UK 6-FSI/C and spring-cage fuse terminal block ST 4-FSI/C Generate product PDF Just to make sure we're on the same page (your question is ambiguous this way), asking to bind TCP on port 0 indicates a request to dynamically generate an unused port number. In other words, the port number you're actually listening on after that request is not zero. Port 2049 is the NFS server port. Is your host running an NFS server? This would prevent anything else from binding on that port. The fact that your netstat output does not show a PID for port 2049 suggests that it is a kernel service using this port. – larsks Apr 5 '19 at 13:30
