  • 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 16995, and is it reachable?

Linux

sudo ss -ltnup 'sport = :16995'      # process listening on 16995
sudo lsof -nP -i :16995

macOS

sudo lsof -nP -i :16995

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 16995 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 16995
netstat -ano | findstr :16995

From another machine

nmap -p 16995 -sV <host>
sudo nmap -sU -p 16995 <host>
nc -zv <host> 16995

Block it in the firewall

sudo ufw deny 16995/tcp                                         # Linux (ufw)

04 FAQ
What is port 16995 used for?

Port 16995 is assigned by IANA to amt-redir-tls (Intel(R) AMT Redirection/TLS).

Is port 16995 TCP or UDP?

Port 16995 is registered for TCP and UDP.

Is it safe to open port 16995?

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 16995 is open?

On Linux run "ss -ltnup 'sport = :16995'", on macOS "lsof -nP -i :16995", and on Windows "netstat -ano | findstr :16995" to see the local process. From another machine, "nmap -p 16995 <host>" shows whether it is reachable.
