  • 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 4312, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4312'      # process listening on 4312
sudo lsof -nP -i :4312

macOS

sudo lsof -nP -i :4312

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4312 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4312
netstat -ano | findstr :4312

From another machine

nmap -p 4312 -sV <host>
nc -zv <host> 4312

Block it in the firewall

sudo ufw deny 4312/tcp                                         # Linux (ufw)

04 FAQ
What is port 4312 used for?

Port 4312 is assigned by IANA to pscl-mgt (Parascale Membership Manager).

Is port 4312 TCP or UDP?

Port 4312 is registered for TCP.

Is it safe to open port 4312?

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 4312 is open?

On Linux run "ss -ltnup 'sport = :4312'", on macOS "lsof -nP -i :4312", and on Windows "netstat -ano | findstr :4312" to see the local process. From another machine, "nmap -p 4312 <host>" shows whether it is reachable.
