01 Security

Is port 5696 dangerous?

We have no specific security note for port 5696. 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 5696, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5696'      # process listening on 5696
sudo lsof -nP -i :5696

macOS

sudo lsof -nP -i :5696

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5696 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5696
netstat -ano | findstr :5696

From another machine

nmap -p 5696 -sV <host>
nc -zv <host> 5696

Block it in the firewall

sudo ufw deny 5696/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 5696" -Direction Inbound -LocalPort 5696 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 5696 used for?

Port 5696 is assigned by IANA to kmip (Key Management Interoperability Protocol).

Is port 5696 TCP or UDP?

Port 5696 is registered for TCP.

Is it safe to open port 5696?

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 5696 is open?

On Linux run "ss -ltnup 'sport = :5696'", on macOS "lsof -nP -i :5696", and on Windows "netstat -ano | findstr :5696" to see the local process. From another machine, "nmap -p 5696 <host>" shows whether it is reachable.
