01 Security

Is port 30001 dangerous?

We have no specific security note for port 30001. 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 30001, and is it reachable?

Linux

sudo ss -ltnup 'sport = :30001'      # process listening on 30001
sudo lsof -nP -i :30001

macOS

sudo lsof -nP -i :30001

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 30001 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 30001
netstat -ano | findstr :30001

From another machine

nmap -p 30001 -sV <host>
sudo nmap -sU -p 30001 <host>
nc -zv <host> 30001

Block it in the firewall

sudo ufw deny 30001/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 30001" -Direction Inbound -LocalPort 30001 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 30001 used for?

Port 30001 is assigned by IANA to pago-services1 (Pago Services 1).

Is port 30001 TCP or UDP?

Port 30001 is registered for TCP and UDP.

Is it safe to open port 30001?

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 30001 is open?

On Linux run "ss -ltnup 'sport = :30001'", on macOS "lsof -nP -i :30001", and on Windows "netstat -ano | findstr :30001" to see the local process. From another machine, "nmap -p 30001 <host>" shows whether it is reachable.
