Is port 11109 dangerous?

We have no specific security note for port 11109. 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 11109, and is it reachable?

Linux

sudo ss -ltnup 'sport = :11109'      # process listening on 11109
sudo lsof -nP -i :11109

macOS

sudo lsof -nP -i :11109

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 11109 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 11109
netstat -ano | findstr :11109

From another machine

nmap -p 11109 -sV <host>
nc -zv <host> 11109

Block it in the firewall

sudo ufw deny 11109/tcp                                         # Linux (ufw)

04 FAQ
What is port 11109 used for?

Port 11109 is assigned by IANA to sgi-dmfmgr (Data migration facility Manager (DMF) is a browser based interface to DMF).

Is port 11109 TCP or UDP?

Port 11109 is registered for TCP.

Is it safe to open port 11109?

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 11109 is open?

On Linux run "ss -ltnup 'sport = :11109'", on macOS "lsof -nP -i :11109", and on Windows "netstat -ano | findstr :11109" to see the local process. From another machine, "nmap -p 11109 <host>" shows whether it is reachable.
