01 Security

Is port 6464 dangerous?

We have no specific security note for port 6464. 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 6464, and is it reachable?

Linux

sudo ss -ltnup 'sport = :6464'      # process listening on 6464
sudo lsof -nP -i :6464

macOS

sudo lsof -nP -i :6464

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 6464 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 6464
netstat -ano | findstr :6464

From another machine

nmap -p 6464 -sV <host>
sudo nmap -sU -p 6464 <host>
nc -zv <host> 6464

Block it in the firewall

sudo ufw deny 6464/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 6464" -Direction Inbound -LocalPort 6464 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 6464 used for?

Port 6464 is assigned by IANA to ieee11073-20701 (Port assignment for medical device communication in accordance to IEEE 11073-20701).

Is port 6464 TCP or UDP?

Port 6464 is registered for TCP and UDP.

Is it safe to open port 6464?

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 6464 is open?

On Linux run "ss -ltnup 'sport = :6464'", on macOS "lsof -nP -i :6464", and on Windows "netstat -ano | findstr :6464" to see the local process. From another machine, "nmap -p 6464 <host>" shows whether it is reachable.
