Is port 2606 dangerous?

We have no specific security note for port 2606. 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 2606, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2606'      # process listening on 2606
sudo lsof -nP -i :2606

macOS

sudo lsof -nP -i :2606

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2606 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2606
netstat -ano | findstr :2606

From another machine

nmap -p 2606 -sV <host>
sudo nmap -sU -p 2606 <host>
nc -zv <host> 2606

Block it in the firewall

sudo ufw deny 2606/tcp                                         # Linux (ufw)

What is port 2606 used for?

Port 2606 is assigned by IANA to netmon (Dell Netmon).

Is port 2606 TCP or UDP?

Port 2606 is registered for TCP and UDP.

Is it safe to open port 2606?

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 2606 is open?

On Linux run "ss -ltnup 'sport = :2606'", on macOS "lsof -nP -i :2606", and on Windows "netstat -ano | findstr :2606" to see the local process. From another machine, "nmap -p 2606 <host>" shows whether it is reachable.
