01 Security

Is port 1536 dangerous?

We have no specific security note for port 1536. 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 1536, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1536'      # process listening on 1536
sudo lsof -nP -i :1536

macOS

sudo lsof -nP -i :1536

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1536 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1536
netstat -ano | findstr :1536

From another machine

nmap -p 1536 -sV <host>
sudo nmap -sU -p 1536 <host>
nc -zv <host> 1536

Block it in the firewall

sudo ufw deny 1536/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1536" -Direction Inbound -LocalPort 1536 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1536 used for?

Port 1536 is assigned by IANA to ampr-inter (ampr-inter).

Is port 1536 TCP or UDP?

Port 1536 is registered for TCP and UDP.

Is it safe to open port 1536?

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 1536 is open?

On Linux run "ss -ltnup 'sport = :1536'", on macOS "lsof -nP -i :1536", and on Windows "netstat -ano | findstr :1536" to see the local process. From another machine, "nmap -p 1536 <host>" shows whether it is reachable.
