Is port 34379 dangerous?

We have no specific security note for port 34379. Its risk depends on the program actually listening on it. General advice for other services services:

  • Close the port if nothing on the host needs it.
  • Identify the process that listens on it (commands below) before opening it in a firewall.
  • Expose a service only to the networks that use it.

03 Check it

Which program uses port 34379, and is it reachable?

Linux

sudo ss -ltnup 'sport = :34379'      # process listening on 34379
sudo lsof -nP -i :34379

macOS

sudo lsof -nP -i :34379

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 34379 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 34379
netstat -ano | findstr :34379

From another machine

nmap -p 34379 -sV <host>
sudo nmap -sU -p 34379 <host>
nc -zv <host> 34379

Block it in the firewall

sudo ufw deny 34379/tcp                                         # Linux (ufw)

04 FAQ
What is port 34379 used for?

Port 34379 is assigned by IANA to p-net-remote (P-Net on IP remote).

Is port 34379 TCP or UDP?

Port 34379 is registered for TCP and UDP.

Is it safe to open port 34379?

It depends on the program that listens on it. Open it only for a service you know and only to the networks that need it. Close the port if nothing on the host needs it.

How do I check if port 34379 is open?

On Linux run "ss -ltnup 'sport = :34379'", on macOS "lsof -nP -i :34379", and on Windows "netstat -ano | findstr :34379" to see the local process. From another machine, "nmap -p 34379 <host>" shows whether it is reachable.
