01 Security

Is port 22000 dangerous?

We have no specific security note for port 22000. 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 22000, and is it reachable?

Linux

sudo ss -ltnup 'sport = :22000'      # process listening on 22000
sudo lsof -nP -i :22000

macOS

sudo lsof -nP -i :22000

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 22000 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 22000
netstat -ano | findstr :22000

From another machine

nmap -p 22000 -sV <host>
sudo nmap -sU -p 22000 <host>
nc -zv <host> 22000

Block it in the firewall

sudo ufw deny 22000/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 22000" -Direction Inbound -LocalPort 22000 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 22000 used for?

Port 22000 is assigned by IANA to snapenetio (SNAPenetIO).

Is port 22000 TCP or UDP?

Port 22000 is registered for TCP and UDP.

Is it safe to open port 22000?

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 22000 is open?

On Linux run "ss -ltnup 'sport = :22000'", on macOS "lsof -nP -i :22000", and on Windows "netstat -ano | findstr :22000" to see the local process. From another machine, "nmap -p 22000 <host>" shows whether it is reachable.
