01 Security

Is port 2243 dangerous?

We have no specific security note for port 2243. 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 2243, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2243'      # process listening on 2243
sudo lsof -nP -i :2243

macOS

sudo lsof -nP -i :2243

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2243 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2243
netstat -ano | findstr :2243

From another machine

nmap -p 2243 -sV <host>
sudo nmap -sU -p 2243 <host>
nc -zv <host> 2243

Block it in the firewall

sudo ufw deny 2243/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2243" -Direction Inbound -LocalPort 2243 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2243 used for?

Port 2243 is assigned by IANA to magicom (Magicom Protocol).

Is port 2243 TCP or UDP?

Port 2243 is registered for TCP and UDP.

Is it safe to open port 2243?

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 2243 is open?

On Linux run "ss -ltnup 'sport = :2243'", on macOS "lsof -nP -i :2243", and on Windows "netstat -ano | findstr :2243" to see the local process. From another machine, "nmap -p 2243 <host>" shows whether it is reachable.
