Is port 1654 dangerous?

We have no specific security note for port 1654. 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 1654, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1654'      # process listening on 1654
sudo lsof -nP -i :1654

macOS

sudo lsof -nP -i :1654

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1654 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1654
netstat -ano | findstr :1654

From another machine

nmap -p 1654 -sV <host>
sudo nmap -sU -p 1654 <host>
nc -zv <host> 1654
