01 Security

Is port 4179 dangerous?

We have no specific security note for port 4179. 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 4179, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4179'      # process listening on 4179
sudo lsof -nP -i :4179

macOS

sudo lsof -nP -i :4179

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4179 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4179
netstat -ano | findstr :4179

From another machine

nmap -p 4179 -sV <host>
sudo nmap -sU -p 4179 <host>
nc -zv <host> 4179

Block it in the firewall

sudo ufw deny 4179/tcp                                         # Linux (ufw)

04 FAQ
What is port 4179 used for?

Port 4179 is assigned by IANA to MaxumSP (Maxum Services).

Is port 4179 TCP or UDP?

Port 4179 is registered for TCP and UDP.

Is it safe to open port 4179?

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 4179 is open?

On Linux run "ss -ltnup 'sport = :4179'", on macOS "lsof -nP -i :4179", and on Windows "netstat -ano | findstr :4179" to see the local process. From another machine, "nmap -p 4179 <host>" shows whether it is reachable.
