Is port 20222 dangerous?

We have no specific security note for port 20222. 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 20222, and is it reachable?

Linux

sudo ss -ltnup 'sport = :20222'      # process listening on 20222
sudo lsof -nP -i :20222

macOS

sudo lsof -nP -i :20222

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 20222 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 20222
netstat -ano | findstr :20222

From another machine

nmap -p 20222 -sV <host>
sudo nmap -sU -p 20222 <host>
nc -zv <host> 20222

Block it in the firewall

sudo ufw deny 20222/tcp                                         # Linux (ufw)

04 FAQ
What is port 20222 used for?

Port 20222 is assigned by IANA to ipulse-ics (iPulse-ICS).

Is port 20222 TCP or UDP?

Port 20222 is registered for TCP and UDP.

Is it safe to open port 20222?

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 20222 is open?

On Linux run "ss -ltnup 'sport = :20222'", on macOS "lsof -nP -i :20222", and on Windows "netstat -ano | findstr :20222" to see the local process. From another machine, "nmap -p 20222 <host>" shows whether it is reachable.
