01 Security

Is port 96 dangerous?

We have no specific security note for port 96. 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 96, and is it reachable?

Linux

sudo ss -ltnup 'sport = :96'      # process listening on 96
sudo lsof -nP -i :96

macOS

sudo lsof -nP -i :96

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 96 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 96
netstat -ano | findstr :96

From another machine

nmap -p 96 -sV <host>
sudo nmap -sU -p 96 <host>
nc -zv <host> 96

Block it in the firewall

sudo ufw deny 96/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 96" -Direction Inbound -LocalPort 96 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 96 used for?

Port 96 is assigned by IANA to dixie (DIXIE Protocol Specification).

Is port 96 TCP or UDP?

Port 96 is registered for TCP and UDP.

Is it safe to open port 96?

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 96 is open?

On Linux run "ss -ltnup 'sport = :96'", on macOS "lsof -nP -i :96", and on Windows "netstat -ano | findstr :96" to see the local process. From another machine, "nmap -p 96 <host>" shows whether it is reachable.
