Is port 2212 dangerous?

We have no specific security note for port 2212. 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 2212, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2212'      # process listening on 2212
sudo lsof -nP -i :2212

macOS

sudo lsof -nP -i :2212

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2212 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2212
netstat -ano | findstr :2212

From another machine

nmap -p 2212 -sV <host>
sudo nmap -sU -p 2212 <host>
nc -zv <host> 2212

Block it in the firewall

sudo ufw deny 2212/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2212" -Direction Inbound -LocalPort 2212 -Protocol TCP -Action Block  # Windows

Is port 2212 TCP or UDP?

Port 2212 is registered for TCP and UDP.

On Linux run "ss -ltnup 'sport = :2212'", on macOS "lsof -nP -i :2212", and on Windows "netstat -ano | findstr :2212" to see the local process. From another machine, "nmap -p 2212 <host>" shows whether it is reachable.
