01 Security

Is port 38001 dangerous?

We have no specific security note for port 38001. 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 38001, and is it reachable?

Linux

sudo ss -ltnup 'sport = :38001'      # process listening on 38001
sudo lsof -nP -i :38001

macOS

sudo lsof -nP -i :38001

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 38001 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 38001
netstat -ano | findstr :38001

From another machine

nmap -p 38001 -sV <host>
nc -zv <host> 38001

Block it in the firewall

sudo ufw deny 38001/tcp                                         # Linux (ufw)

What is port 38001 used for?

Port 38001 is assigned by IANA to ivs-insertion (InfoVista Server Insertion).

Is port 38001 TCP or UDP?

Port 38001 is registered for TCP.

Is it safe to open port 38001?

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 38001 is open?

On Linux run "ss -ltnup 'sport = :38001'", on macOS "lsof -nP -i :38001", and on Windows "netstat -ano | findstr :38001" to see the local process. From another machine, "nmap -p 38001 <host>" shows whether it is reachable.
