01 Security

Is port 2589 dangerous?

We have no specific security note for port 2589. 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 2589, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2589'      # process listening on 2589
sudo lsof -nP -i :2589

macOS

sudo lsof -nP -i :2589

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2589 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2589
netstat -ano | findstr :2589

From another machine

nmap -p 2589 -sV <host>
sudo nmap -sU -p 2589 <host>
nc -zv <host> 2589

Block it in the firewall

sudo ufw deny 2589/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2589" -Direction Inbound -LocalPort 2589 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2589 used for?

Port 2589 is assigned by IANA to quartus-tcl (quartus tcl).

Is port 2589 TCP or UDP?

Port 2589 is registered for TCP and UDP.

Is it safe to open port 2589?

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 2589 is open?

On Linux run "ss -ltnup 'sport = :2589'", on macOS "lsof -nP -i :2589", and on Windows "netstat -ano | findstr :2589" to see the local process. From another machine, "nmap -p 2589 <host>" shows whether it is reachable.
