Is port 5814 dangerous?

We have no specific security note for port 5814. 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 5814, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5814'      # process listening on 5814
sudo lsof -nP -i :5814

macOS

sudo lsof -nP -i :5814

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5814 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5814
netstat -ano | findstr :5814

From another machine

nmap -p 5814 -sV <host>
sudo nmap -sU -p 5814 <host>
nc -zv <host> 5814

Block it in the firewall

sudo ufw deny 5814/tcp                                         # Linux (ufw)

Port 5814 is assigned by IANA to spt-automation (Support Automation).

Is port 5814 TCP or UDP?

Port 5814 is registered for TCP and UDP.

Is it safe to open port 5814?

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 5814 is open?

On Linux run "ss -ltnup 'sport = :5814'", on macOS "lsof -nP -i :5814", and on Windows "netstat -ano | findstr :5814" to see the local process. From another machine, "nmap -p 5814 <host>" shows whether it is reachable.
