01 Security

Is port 1199 dangerous?

We have no specific security note for port 1199. 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 1199, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1199'      # process listening on 1199
sudo lsof -nP -i :1199

macOS

sudo lsof -nP -i :1199

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1199 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1199
netstat -ano | findstr :1199

From another machine

nmap -p 1199 -sV <host>
sudo nmap -sU -p 1199 <host>
nc -zv <host> 1199

Block it in the firewall

sudo ufw deny 1199/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1199" -Direction Inbound -LocalPort 1199 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1199 used for?

Port 1199 is assigned by IANA to dmidi (DMIDI).

Is port 1199 TCP or UDP?

Port 1199 is registered for TCP and UDP.

Is it safe to open port 1199?

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 1199 is open?

On Linux run "ss -ltnup 'sport = :1199'", on macOS "lsof -nP -i :1199", and on Windows "netstat -ano | findstr :1199" to see the local process. From another machine, "nmap -p 1199 <host>" shows whether it is reachable.
