01 Security

Is port 6306 dangerous?

We have no specific security note for port 6306. 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 6306, and is it reachable?

Linux

sudo ss -ltnup 'sport = :6306'      # process listening on 6306
sudo lsof -nP -i :6306

macOS

sudo lsof -nP -i :6306

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 6306 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 6306
netstat -ano | findstr :6306

From another machine

nmap -p 6306 -sV <host>
sudo nmap -sU -p 6306 <host>
nc -zv <host> 6306

Block it in the firewall

sudo ufw deny 6306/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 6306" -Direction Inbound -LocalPort 6306 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 6306 used for?

Port 6306 is assigned by IANA to ufmp (Unified Fabric Management Protocol).

Is port 6306 TCP or UDP?

Port 6306 is registered for TCP and UDP.

Is it safe to open port 6306?

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 6306 is open?

On Linux run "ss -ltnup 'sport = :6306'", on macOS "lsof -nP -i :6306", and on Windows "netstat -ano | findstr :6306" to see the local process. From another machine, "nmap -p 6306 <host>" shows whether it is reachable.
