01 Security

Is port 6624 dangerous?

We have no specific security note for port 6624. 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 6624, and is it reachable?

Linux

sudo ss -ltnup 'sport = :6624'      # process listening on 6624
sudo lsof -nP -i :6624

macOS

sudo lsof -nP -i :6624

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 6624 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 6624
netstat -ano | findstr :6624

From another machine

nmap -p 6624 -sV <host>
nc -zv <host> 6624

Block it in the firewall

sudo ufw deny 6624/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 6624" -Direction Inbound -LocalPort 6624 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 6624 used for?

Port 6624 is assigned by IANA to datascaler-db (DataScaler database).

Is port 6624 TCP or UDP?

Port 6624 is registered for TCP.

Is it safe to open port 6624?

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 6624 is open?

On Linux run "ss -ltnup 'sport = :6624'", on macOS "lsof -nP -i :6624", and on Windows "netstat -ano | findstr :6624" to see the local process. From another machine, "nmap -p 6624 <host>" shows whether it is reachable.
