Is port 1829 dangerous?

We have no specific security note for port 1829. 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 1829, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1829'      # process listening on 1829
sudo lsof -nP -i :1829

macOS

sudo lsof -nP -i :1829

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1829 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1829
netstat -ano | findstr :1829

From another machine

nmap -p 1829 -sV <host>
sudo nmap -sU -p 1829 <host>
nc -zv <host> 1829

Block it in the firewall

sudo ufw deny 1829/tcp                                         # Linux (ufw)

04 FAQ
What is port 1829 used for?

Port 1829 is assigned by IANA to optika-emedia (Optika eMedia).

Is port 1829 TCP or UDP?

Port 1829 is registered for TCP and UDP.

Is it safe to open port 1829?

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 1829 is open?

On Linux run "ss -ltnup 'sport = :1829'", on macOS "lsof -nP -i :1829", and on Windows "netstat -ano | findstr :1829" to see the local process. From another machine, "nmap -p 1829 <host>" shows whether it is reachable.
