01 Security

Is port 4152 dangerous?

We have no specific security note for port 4152. 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 4152, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4152'      # process listening on 4152
sudo lsof -nP -i :4152

macOS

sudo lsof -nP -i :4152

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4152 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4152
netstat -ano | findstr :4152

From another machine

nmap -p 4152 -sV <host>
sudo nmap -sU -p 4152 <host>
nc -zv <host> 4152

Block it in the firewall

sudo ufw deny 4152/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 4152" -Direction Inbound -LocalPort 4152 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 4152 used for?

Port 4152 is assigned by IANA to idig_mux (iDigTech Multiplex), idig-mux (iDigTech Multiplex IANA assigned this well-formed service name as a replacement for "idig_mux".).

Is port 4152 TCP or UDP?

Port 4152 is registered for TCP and UDP.

Is it safe to open port 4152?

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 4152 is open?

On Linux run "ss -ltnup 'sport = :4152'", on macOS "lsof -nP -i :4152", and on Windows "netstat -ano | findstr :4152" to see the local process. From another machine, "nmap -p 4152 <host>" shows whether it is reachable.
