01 Security

Is port 3355 dangerous?

We have no specific security note for port 3355. 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 3355, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3355'      # process listening on 3355
sudo lsof -nP -i :3355

macOS

sudo lsof -nP -i :3355

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3355 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3355
netstat -ano | findstr :3355

From another machine

nmap -p 3355 -sV <host>
sudo nmap -sU -p 3355 <host>
nc -zv <host> 3355

Block it in the firewall

sudo ufw deny 3355/tcp                                         # Linux (ufw)

04 FAQ
What is port 3355 used for?

Port 3355 is assigned by IANA to ordinox-dbase (Ordinox Dbase).

Is port 3355 TCP or UDP?

Port 3355 is registered for TCP and UDP.

Is it safe to open port 3355?

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 3355 is open?

On Linux run "ss -ltnup 'sport = :3355'", on macOS "lsof -nP -i :3355", and on Windows "netstat -ano | findstr :3355" to see the local process. From another machine, "nmap -p 3355 <host>" shows whether it is reachable.
