Is port 6505 dangerous?

We have no specific security note for port 6505. 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 6505, and is it reachable?

Linux

sudo ss -ltnup 'sport = :6505'      # process listening on 6505
sudo lsof -nP -i :6505

macOS

sudo lsof -nP -i :6505

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 6505 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 6505
netstat -ano | findstr :6505

From another machine

nmap -p 6505 -sV <host>
sudo nmap -sU -p 6505 <host>
nc -zv <host> 6505

Block it in the firewall

sudo ufw deny 6505/tcp                                         # Linux (ufw)

04 FAQ
What is port 6505 used for?

Port 6505 is assigned by IANA to badm_priv (BoKS Admin Private Port), badm-priv (BoKS Admin Private Port IANA assigned this well-formed service name as a replacement for "badm_priv".).

Is port 6505 TCP or UDP?

Port 6505 is registered for TCP and UDP.

Is it safe to open port 6505?

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 6505 is open?

On Linux run "ss -ltnup 'sport = :6505'", on macOS "lsof -nP -i :6505", and on Windows "netstat -ano | findstr :6505" to see the local process. From another machine, "nmap -p 6505 <host>" shows whether it is reachable.
