Which program uses port 29999, and is it reachable?
Linux
sudo ss -ltnup 'sport = :29999' # process listening on 29999
sudo lsof -nP -i :29999macOS
sudo lsof -nP -i :29999
Windows (PowerShell)
Get-NetTCPConnection -LocalPort 29999 -State Listen | Select LocalAddress, OwningProcess Get-NetUDPEndpoint -LocalPort 29999 netstat -ano | findstr :29999
From another machine
nmap -p 29999 -sV <host> nc -zv <host> 29999
Block it in the firewall
sudo ufw deny 29999/tcp # Linux (ufw) New-NetFirewallRule -DisplayName "Block 29999" -Direction Inbound -LocalPort 29999 -Protocol TCP -Action Block # Windows
What is port 29999 used for?
Port 29999 is assigned by IANA to bingbang (data exchange protocol for IEC61850 in wind power plants).
Is port 29999 TCP or UDP?
Port 29999 is registered for TCP.
Is it safe to open port 29999?
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. Industrial and IoT protocols often have no authentication: never expose them to the Internet.
How do I check if port 29999 is open?
On Linux run "ss -ltnup 'sport = :29999'", on macOS "lsof -nP -i :29999", and on Windows "netstat -ano | findstr :29999" to see the local process. From another machine, "nmap -p 29999 <host>" shows whether it is reachable.
