Is port 4156 dangerous?

We have no specific security note for port 4156. 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 4156, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4156'      # process listening on 4156
sudo lsof -nP -i :4156

macOS

sudo lsof -nP -i :4156

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4156 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4156
netstat -ano | findstr :4156

From another machine

nmap -p 4156 -sV <host>
sudo nmap -sU -p 4156 <host>
nc -zv <host> 4156

Block it in the firewall

sudo ufw deny 4156/tcp                                         # Linux (ufw)

04 FAQ
What is port 4156 used for?

Port 4156 is assigned by IANA to stat-results (STAT Results).

Is port 4156 TCP or UDP?

Port 4156 is registered for TCP and UDP.

Is it safe to open port 4156?

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 4156 is open?

On Linux run "ss -ltnup 'sport = :4156'", on macOS "lsof -nP -i :4156", and on Windows "netstat -ano | findstr :4156" to see the local process. From another machine, "nmap -p 4156 <host>" shows whether it is reachable.
