01 Security

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

What is port 2276 used for?

Port 2276 is assigned by IANA to ibridge-mgmt (iBridge Management).

Is port 2276 TCP or UDP?

Port 2276 is registered for TCP and UDP.

Is it safe to open port 2276?

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.
