Is port 6064 dangerous?

We have no specific security note for port 6064. 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 6064, and is it reachable?

Linux

sudo ss -ltnup 'sport = :6064'      # process listening on 6064
sudo lsof -nP -i :6064

macOS

sudo lsof -nP -i :6064

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 6064 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 6064
netstat -ano | findstr :6064

From another machine

nmap -p 6064 -sV <host>
sudo nmap -sU -p 6064 <host>
nc -zv <host> 6064

Block it in the firewall

sudo ufw deny 6064/tcp                                         # Linux (ufw)

What is port 6064 used for?

Port 6064 is assigned by IANA to ndl-ahp-svc (NDL-AHP-SVC).

Is port 6064 TCP or UDP?

Port 6064 is registered for TCP and UDP.

Is it safe to open port 6064?

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 6064 is open?

On Linux run "ss -ltnup 'sport = :6064'", on macOS "lsof -nP -i :6064", and on Windows "netstat -ano | findstr :6064" to see the local process. From another machine, "nmap -p 6064 <host>" shows whether it is reachable.
