01 Security

Is port 2275 dangerous?

We have no specific security note for port 2275. 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 2275, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2275'      # process listening on 2275
sudo lsof -nP -i :2275

macOS

sudo lsof -nP -i :2275

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2275 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2275
netstat -ano | findstr :2275

From another machine

nmap -p 2275 -sV <host>
sudo nmap -sU -p 2275 <host>
nc -zv <host> 2275

Block it in the firewall

sudo ufw deny 2275/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2275" -Direction Inbound -LocalPort 2275 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2275 used for?

Port 2275 is assigned by IANA to ibridge-data (iBridge Conferencing).

Is port 2275 TCP or UDP?

Port 2275 is registered for TCP and UDP.

Is it safe to open port 2275?

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 2275 is open?

On Linux run "ss -ltnup 'sport = :2275'", on macOS "lsof -nP -i :2275", and on Windows "netstat -ano | findstr :2275" to see the local process. From another machine, "nmap -p 2275 <host>" shows whether it is reachable.
