01 Security

Is port 3050 dangerous?

We have no specific security note for port 3050. 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 3050, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3050'      # process listening on 3050
sudo lsof -nP -i :3050

macOS

sudo lsof -nP -i :3050

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3050 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3050
netstat -ano | findstr :3050

From another machine

nmap -p 3050 -sV <host>
sudo nmap -sU -p 3050 <host>
nc -zv <host> 3050

Block it in the firewall

sudo ufw deny 3050/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3050" -Direction Inbound -LocalPort 3050 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 3050 used for?

Port 3050 is assigned by IANA to gds_db (gds_db), gds-db (gds_db IANA assigned this well-formed service name as a replacement for "gds_db".).

Is port 3050 TCP or UDP?

Port 3050 is registered for TCP and UDP.

Is it safe to open port 3050?

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 3050 is open?

On Linux run "ss -ltnup 'sport = :3050'", on macOS "lsof -nP -i :3050", and on Windows "netstat -ano | findstr :3050" to see the local process. From another machine, "nmap -p 3050 <host>" shows whether it is reachable.
