Is port 4794 dangerous?

We have no specific security note for port 4794. 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 4794, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4794'      # process listening on 4794
sudo lsof -nP -i :4794

macOS

sudo lsof -nP -i :4794

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4794 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4794
netstat -ano | findstr :4794

From another machine

nmap -p 4794 -sV <host>
sudo nmap -sU -p 4794 <host>
nc -zv <host> 4794

Block it in the firewall

sudo ufw deny 4794/udp                                         # Linux (ufw)

Is port 4794 TCP or UDP?

Port 4794 is registered for UDP.

Is it safe to open port 4794?

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 4794 is open?

On Linux run "ss -ltnup 'sport = :4794'", on macOS "lsof -nP -i :4794", and on Windows "netstat -ano | findstr :4794" to see the local process. From another machine, "nmap -p 4794 <host>" shows whether it is reachable.
