01 Security

Is port 38000 dangerous?

We have no specific security note for port 38000. Its risk depends on the program actually listening on it. General advice for databases & caches services:

  • Bind the service to localhost or a private network, never to a public address.
  • Enable authentication, use per-application accounts and require TLS.
  • Watch for exposed Docker ports: publish them on 127.0.0.1 only.

03 Check it

Which program uses port 38000, and is it reachable?

Linux

sudo ss -ltnup 'sport = :38000'      # process listening on 38000
sudo lsof -nP -i :38000

macOS

sudo lsof -nP -i :38000

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 38000 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 38000
netstat -ano | findstr :38000

From another machine

nmap -p 38000 -sV <host>
nc -zv <host> 38000

Block it in the firewall

sudo ufw deny 38000/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 38000" -Direction Inbound -LocalPort 38000 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 38000 used for?

Port 38000 is assigned by IANA to ivs-database (InfoVista Server Database).

Is port 38000 TCP or UDP?

Port 38000 is registered for TCP.

Is it safe to open port 38000?

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. Bind the service to localhost or a private network, never to a public address.

How do I check if port 38000 is open?

On Linux run "ss -ltnup 'sport = :38000'", on macOS "lsof -nP -i :38000", and on Windows "netstat -ano | findstr :38000" to see the local process. From another machine, "nmap -p 38000 <host>" shows whether it is reachable.
