Is port 1592 dangerous?

We have no specific security note for port 1592. 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 1592, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1592'      # process listening on 1592
sudo lsof -nP -i :1592

macOS

sudo lsof -nP -i :1592

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1592 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1592
netstat -ano | findstr :1592

From another machine

nmap -p 1592 -sV <host>
sudo nmap -sU -p 1592 <host>
nc -zv <host> 1592

Block it in the firewall

sudo ufw deny 1592/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1592" -Direction Inbound -LocalPort 1592 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1592 used for?

Port 1592 is assigned by IANA to commonspace (commonspace).

Is port 1592 TCP or UDP?

Port 1592 is registered for TCP and UDP.

Is it safe to open port 1592?

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 1592 is open?

On Linux run "ss -ltnup 'sport = :1592'", on macOS "lsof -nP -i :1592", and on Windows "netstat -ano | findstr :1592" to see the local process. From another machine, "nmap -p 1592 <host>" shows whether it is reachable.
