- 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.

Which program uses port 3322, and is it reachable?
Linux
sudo ss -ltnup 'sport = :3322' # process listening on 3322
sudo lsof -nP -i :3322macOS
sudo lsof -nP -i :3322
Windows (PowerShell)
Get-NetTCPConnection -LocalPort 3322 -State Listen | Select LocalAddress, OwningProcess Get-NetUDPEndpoint -LocalPort 3322 netstat -ano | findstr :3322
From another machine
nmap -p 3322 -sV <host> nc -zv <host> 3322

What is port 3322 used for?
Port 3322 is assigned by IANA to active-net (Active Networks).
Is port 3322 TCP or UDP?
Port 3322 has no registered transport. Any program can still use it over TCP or UDP.
Is it safe to open port 3322?
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 3322 is open?
On Linux run "ss -ltnup 'sport = :3322'", on macOS "lsof -nP -i :3322", and on Windows "netstat -ano | findstr :3322" to see the local process. From another machine, "nmap -p 3322 <host>" shows whether it is reachable.
