Is port 2696 dangerous?

We have no specific security note for port 2696. 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 2696, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2696'      # process listening on 2696
sudo lsof -nP -i :2696

macOS

sudo lsof -nP -i :2696

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2696 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2696
netstat -ano | findstr :2696

From another machine

nmap -p 2696 -sV <host>
sudo nmap -sU -p 2696 <host>
nc -zv <host> 2696

Block it in the firewall

sudo ufw deny 2696/tcp                                         # Linux (ufw)

On Linux run "ss -ltnup 'sport = :2696'", on macOS "lsof -nP -i :2696", and on Windows "netstat -ano | findstr :2696" to see the local process. From another machine, "nmap -p 2696 <host>" shows whether it is reachable.
