01 Security

Is port 5424 dangerous?

We have no specific security note for port 5424. 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 5424, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5424'      # process listening on 5424
sudo lsof -nP -i :5424

macOS

sudo lsof -nP -i :5424

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5424 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5424
netstat -ano | findstr :5424

From another machine

nmap -p 5424 -sV <host>
sudo nmap -sU -p 5424 <host>
nc -zv <host> 5424

Block it in the firewall

sudo ufw deny 5424/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 5424" -Direction Inbound -LocalPort 5424 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 5424 used for?

Port 5424 is assigned by IANA to beyond-remote (Beyond Remote).

Is port 5424 TCP or UDP?

Port 5424 is registered for TCP and UDP.

Is it safe to open port 5424?

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 5424 is open?

On Linux run "ss -ltnup 'sport = :5424'", on macOS "lsof -nP -i :5424", and on Windows "netstat -ano | findstr :5424" to see the local process. From another machine, "nmap -p 5424 <host>" shows whether it is reachable.
