Is port 2829 dangerous?

We have no specific security note for port 2829. 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 2829, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2829'      # process listening on 2829
sudo lsof -nP -i :2829

macOS

sudo lsof -nP -i :2829

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2829 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2829
netstat -ano | findstr :2829

From another machine

nmap -p 2829 -sV <host>
sudo nmap -sU -p 2829 <host>
nc -zv <host> 2829

Block it in the firewall

sudo ufw deny 2829/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2829" -Direction Inbound -LocalPort 2829 -Protocol TCP -Action Block  # Windows

What is port 2829 used for?

Port 2829 is assigned by IANA to silkp1 (silkp1).

Is port 2829 TCP or UDP?

Port 2829 is registered for TCP and UDP.

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 2829 is open?

On Linux run "ss -ltnup 'sport = :2829'", on macOS "lsof -nP -i :2829", and on Windows "netstat -ano | findstr :2829" to see the local process. From another machine, "nmap -p 2829 <host>" shows whether it is reachable.
