Is port 1922 dangerous?

We have no specific security note for port 1922. 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 1922, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1922'      # process listening on 1922
sudo lsof -nP -i :1922

macOS

sudo lsof -nP -i :1922

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1922 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1922
netstat -ano | findstr :1922

From another machine

nmap -p 1922 -sV <host>
sudo nmap -sU -p 1922 <host>
nc -zv <host> 1922

Block it in the firewall

sudo ufw deny 1922/tcp                                         # Linux (ufw)

What is port 1922 used for?

Port 1922 is assigned by IANA to tapestry (Tapestry).

Is port 1922 TCP or UDP?

Port 1922 is registered for TCP and UDP.

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 1922 is open?

On Linux run "ss -ltnup 'sport = :1922'", on macOS "lsof -nP -i :1922", and on Windows "netstat -ano | findstr :1922" to see the local process. From another machine, "nmap -p 1922 <host>" shows whether it is reachable.
