01 Security

Is port 2583 dangerous?

We have no specific security note for port 2583. 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 2583, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2583'      # process listening on 2583
sudo lsof -nP -i :2583

macOS

sudo lsof -nP -i :2583

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2583 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2583
netstat -ano | findstr :2583

From another machine

nmap -p 2583 -sV <host>
sudo nmap -sU -p 2583 <host>
nc -zv <host> 2583

Block it in the firewall

sudo ufw deny 2583/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2583" -Direction Inbound -LocalPort 2583 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2583 used for?

Port 2583 is assigned by IANA to mon (MON).

Is port 2583 TCP or UDP?

Port 2583 is registered for TCP and UDP.

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 2583 is open?

On Linux run "ss -ltnup 'sport = :2583'", on macOS "lsof -nP -i :2583", and on Windows "netstat -ano | findstr :2583" to see the local process. From another machine, "nmap -p 2583 <host>" shows whether it is reachable.
