01 Security

Is port 4300 dangerous?

We have no specific security note for port 4300. 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 4300, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4300'      # process listening on 4300
sudo lsof -nP -i :4300

macOS

sudo lsof -nP -i :4300

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4300 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4300
netstat -ano | findstr :4300

From another machine

nmap -p 4300 -sV <host>
sudo nmap -sU -p 4300 <host>
nc -zv <host> 4300

Block it in the firewall

sudo ufw deny 4300/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 4300" -Direction Inbound -LocalPort 4300 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 4300 used for?

Port 4300 is assigned by IANA to corelccam (Corel CCam).

Is port 4300 TCP or UDP?

Port 4300 is registered for TCP and UDP.

Is it safe to open port 4300?

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 4300 is open?

On Linux run "ss -ltnup 'sport = :4300'", on macOS "lsof -nP -i :4300", and on Windows "netstat -ano | findstr :4300" to see the local process. From another machine, "nmap -p 4300 <host>" shows whether it is reachable.
