Is port 1967 dangerous?

  • 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.

sudo lsof -nP -i :1967

macOS

sudo lsof -nP -i :1967

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1967 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1967
netstat -ano | findstr :1967

From another machine

nmap -p 1967 -sV <host>
sudo nmap -sU -p 1967 <host>
nc -zv <host> 1967
