Technical Details

what runs on :34379

P-NET is an industrial fieldbus used to exchange process data among automation devices. The p-net-remote assignment identifies the remote-access form of P-NET on IP; IANA lists both TCP and UDP, but that alone does not establish which transport a particular implementation uses. In practice, expect a P-NET gateway or related automation equipment rather than a general-purpose internet service. A universal handshake, framing, or deployment default for this port is not established here.

Security Information

exposure of :34379

risk score

2/ 10safe

routine exposure. this port is rarely the way in on its own — keep it patched and logged and move on.

network services averages 2.6 across 1,984 ports — this one sits 0.6 below.

cleartext

credentials and payloads are readable by anyone on path

assignment

official

registered with iana for this service — scanners fingerprint it by number

reachable over

tcp · udp

udp is connectionless — source addresses are trivially spoofed and it is a reflection favourite

security overview

Treat an exposed listener as a path toward industrial automation devices, not as a harmless generic network service. Keep it off the public internet and restrict access to trusted networks or a protected remote-access channel; the port assignment does not establish that implementations authenticate users or encrypt traffic.
