Is port 7164 dangerous?

We have no specific security note for port 7164. 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 7164, and is it reachable?

Linux

sudo ss -ltnup 'sport = :7164'      # process listening on 7164
sudo lsof -nP -i :7164

macOS

sudo lsof -nP -i :7164

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 7164 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 7164
netstat -ano | findstr :7164

From another machine

nmap -p 7164 -sV <host>
sudo nmap -sU -p 7164 <host>
nc -zv <host> 7164

Block it in the firewall

sudo ufw deny 7164/tcp                                         # Linux (ufw)

Is port 7164 TCP or UDP?

Port 7164 is registered for TCP and UDP.

Is it safe to open port 7164?

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 7164 is open?

On Linux run "ss -ltnup 'sport = :7164'", on macOS "lsof -nP -i :7164", and on Windows "netstat -ano | findstr :7164" to see the local process. From another machine, "nmap -p 7164 <host>" shows whether it is reachable.
