Is port 1716 dangerous?

We have no specific security note for port 1716. 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 1716, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1716'      # process listening on 1716
sudo lsof -nP -i :1716

macOS

sudo lsof -nP -i :1716

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1716 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1716
netstat -ano | findstr :1716

From another machine

nmap -p 1716 -sV <host>
sudo nmap -sU -p 1716 <host>
nc -zv <host> 1716

Block it in the firewall

sudo ufw deny 1716/tcp                                         # Linux (ufw)

04 FAQ
What is port 1716 used for?

Port 1716 is assigned by IANA to xmsg (xmsg).

Is port 1716 TCP or UDP?

Port 1716 is registered for TCP and UDP.

Is it safe to open port 1716?

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 1716 is open?

On Linux run "ss -ltnup 'sport = :1716'", on macOS "lsof -nP -i :1716", and on Windows "netstat -ano | findstr :1716" to see the local process. From another machine, "nmap -p 1716 <host>" shows whether it is reachable.
