01 Security

Is port 29000 dangerous?

We have no specific security note for port 29000. 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 29000, and is it reachable?

Linux

sudo ss -ltnup 'sport = :29000'      # process listening on 29000
sudo lsof -nP -i :29000

macOS

sudo lsof -nP -i :29000

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 29000 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 29000
netstat -ano | findstr :29000

From another machine

nmap -p 29000 -sV <host>
nc -zv <host> 29000

Block it in the firewall

sudo ufw deny 29000/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 29000" -Direction Inbound -LocalPort 29000 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 29000 used for?

Port 29000 is assigned by IANA to saltd-licensing (Siemens Licensing Server).

Is port 29000 TCP or UDP?

Port 29000 is registered for TCP.

Is it safe to open port 29000?

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 29000 is open?

On Linux run "ss -ltnup 'sport = :29000'", on macOS "lsof -nP -i :29000", and on Windows "netstat -ano | findstr :29000" to see the local process. From another machine, "nmap -p 29000 <host>" shows whether it is reachable.
