Is port 11320 dangerous?

We have no specific security note for port 11320. 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 11320, and is it reachable?

Linux

sudo ss -ltnup 'sport = :11320'      # process listening on 11320
sudo lsof -nP -i :11320

macOS

sudo lsof -nP -i :11320

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 11320 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 11320
netstat -ano | findstr :11320

From another machine

nmap -p 11320 -sV <host>
sudo nmap -sU -p 11320 <host>
nc -zv <host> 11320

Block it in the firewall

sudo ufw deny 11320/tcp                                         # Linux (ufw)

04 FAQ
What is port 11320 used for?

Port 11320 is assigned by IANA to imip-channels (IMIP Channels Port).

Is port 11320 TCP or UDP?

Port 11320 is registered for TCP and UDP.

Is it safe to open port 11320?

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 11320 is open?

On Linux run "ss -ltnup 'sport = :11320'", on macOS "lsof -nP -i :11320", and on Windows "netstat -ano | findstr :11320" to see the local process. From another machine, "nmap -p 11320 <host>" shows whether it is reachable.
