Is port 8732 dangerous?

We have no specific security note for port 8732. 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 8732, and is it reachable?

Linux

sudo ss -ltnup 'sport = :8732'      # process listening on 8732
sudo lsof -nP -i :8732

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 8732 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 8732
netstat -ano | findstr :8732

From another machine

nmap -p 8732 -sV <host>
sudo nmap -sU -p 8732 <host>
nc -zv <host> 8732

Block it in the firewall

Is port 8732 TCP or UDP?

Port 8732 is registered for 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 8732 is open?

On Linux run "ss -ltnup 'sport = :8732'", on macOS "lsof -nP -i :8732", and on Windows "netstat -ano | findstr :8732" to see the local process. From another machine, "nmap -p 8732 <host>" shows whether it is reachable.
