01 Security

Is port 4558 dangerous?

We have no specific security note for port 4558. 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 4558, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4558'      # process listening on 4558
sudo lsof -nP -i :4558

macOS

sudo lsof -nP -i :4558

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4558 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4558
netstat -ano | findstr :4558

From another machine

nmap -p 4558 -sV <host>
sudo nmap -sU -p 4558 <host>
nc -zv <host> 4558

Block it in the firewall

sudo ufw deny 4558/udp                                         # Linux (ufw)

04 FAQ
What is port 4558 used for?

Port 4558 is assigned by IANA to mtcevrunqman (Marathon everRun Quorum Service Manager).

Is port 4558 TCP or UDP?

Port 4558 is registered for UDP.

Is it safe to open port 4558?

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 4558 is open?

On Linux run "ss -ltnup 'sport = :4558'", on macOS "lsof -nP -i :4558", and on Windows "netstat -ano | findstr :4558" to see the local process. From another machine, "nmap -p 4558 <host>" shows whether it is reachable.
