01 Security

Is port 7962 dangerous?

We have no specific security note for port 7962. 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 7962, and is it reachable?

Linux

sudo ss -ltnup 'sport = :7962'      # process listening on 7962
sudo lsof -nP -i :7962

macOS

sudo lsof -nP -i :7962

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 7962 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 7962
netstat -ano | findstr :7962

From another machine

nmap -p 7962 -sV <host>
sudo nmap -sU -p 7962 <host>
nc -zv <host> 7962

Block it in the firewall

Is port 7962 TCP or UDP?

Port 7962 is registered for TCP and UDP.

Is it safe to open port 7962?

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 7962 is open?

On Linux run "ss -ltnup 'sport = :7962'", on macOS "lsof -nP -i :7962", and on Windows "netstat -ano | findstr :7962" to see the local process. From another machine, "nmap -p 7962 <host>" shows whether it is reachable.
