Is port 2352 dangerous?

We have no specific security note for port 2352. 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 2352, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2352'      # process listening on 2352
sudo lsof -nP -i :2352

macOS

sudo lsof -nP -i :2352

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2352 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2352
netstat -ano | findstr :2352

From another machine

nmap -p 2352 -sV <host>
sudo nmap -sU -p 2352 <host>
nc -zv <host> 2352

Block it in the firewall

sudo ufw deny 2352/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2352" -Direction Inbound -LocalPort 2352 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2352 used for?

Port 2352 is assigned by IANA to pslserver (pslserver).

Is port 2352 TCP or UDP?

Port 2352 is registered for TCP and UDP.

Is it safe to open port 2352?

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 2352 is open?

On Linux run "ss -ltnup 'sport = :2352'", on macOS "lsof -nP -i :2352", and on Windows "netstat -ano | findstr :2352" to see the local process. From another machine, "nmap -p 2352 <host>" shows whether it is reachable.
