01 Security

Is port 692 dangerous?

We have no specific security note for port 692. 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 692, and is it reachable?

Linux

sudo ss -ltnup 'sport = :692'      # process listening on 692
sudo lsof -nP -i :692

macOS

sudo lsof -nP -i :692

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 692 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 692
netstat -ano | findstr :692

From another machine

nmap -p 692 -sV <host>
sudo nmap -sU -p 692 <host>
nc -zv <host> 692

Block it in the firewall

sudo ufw deny 692/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 692" -Direction Inbound -LocalPort 692 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 692 used for?

Port 692 is assigned by IANA to hyperwave-isp (Hyperwave-ISP).

Is port 692 TCP or UDP?

Port 692 is registered for TCP and UDP.

Is it safe to open port 692?

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 692 is open?

On Linux run "ss -ltnup 'sport = :692'", on macOS "lsof -nP -i :692", and on Windows "netstat -ano | findstr :692" to see the local process. From another machine, "nmap -p 692 <host>" shows whether it is reachable.
