Is port 2276 dangerous?

We have no specific security note for port 2276. 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 2276, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2276'      # process listening on 2276
sudo lsof -nP -i :2276

macOS

sudo lsof -nP -i :2276

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2276 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2276
netstat -ano | findstr :2276

From another machine

nmap -p 2276 -sV <host>
sudo nmap -sU -p 2276 <host>
nc -zv <host> 2276

Block it in the firewall

sudo ufw deny 2276/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2276" -Direction Inbound -LocalPort 2276 -Protocol TCP -Action Block  # Windows

Is port 2276 TCP or UDP?

Port 2276 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 2276 is open?

On Linux run "ss -ltnup 'sport = :2276'", on macOS "lsof -nP -i :2276", and on Windows "netstat -ano | findstr :2276" to see the local process. From another machine, "nmap -p 2276 <host>" shows whether it is reachable.
