Is port 2594 dangerous?

We have no specific security note for port 2594. 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 2594, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2594'      # process listening on 2594
sudo lsof -nP -i :2594

macOS

sudo lsof -nP -i :2594

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2594 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2594
netstat -ano | findstr :2594

From another machine

nmap -p 2594 -sV <host>
sudo nmap -sU -p 2594 <host>
nc -zv <host> 2594

Block it in the firewall

sudo ufw deny 2594/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2594" -Direction Inbound -LocalPort 2594 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2594 used for?

Port 2594 is assigned by IANA to dts (Data Base Server).

Is port 2594 TCP or UDP?

Port 2594 is registered for TCP and UDP.

Is it safe to open port 2594?

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 2594 is open?

On Linux run "ss -ltnup 'sport = :2594'", on macOS "lsof -nP -i :2594", and on Windows "netstat -ano | findstr :2594" to see the local process. From another machine, "nmap -p 2594 <host>" shows whether it is reachable.
