Is port 2026 dangerous?

We have no specific security note for port 2026. 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 2026, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2026'      # process listening on 2026
sudo lsof -nP -i :2026

macOS

sudo lsof -nP -i :2026

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2026 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2026
netstat -ano | findstr :2026

From another machine

nmap -p 2026 -sV <host>
sudo nmap -sU -p 2026 <host>
nc -zv <host> 2026

Block it in the firewall

sudo ufw deny 2026/tcp                                         # Linux (ufw)

What is port 2026 used for?

Port 2026 is assigned by IANA to scrabble ().

Is port 2026 TCP or UDP?

Port 2026 is registered for TCP and UDP.

Is it safe to open port 2026?

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 2026 is open?

On Linux run "ss -ltnup 'sport = :2026'", on macOS "lsof -nP -i :2026", and on Windows "netstat -ano | findstr :2026" to see the local process. From another machine, "nmap -p 2026 <host>" shows whether it is reachable.
