01 Security

Is port 2497 dangerous?

We have no specific security note for port 2497. 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 2497, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2497'      # process listening on 2497
sudo lsof -nP -i :2497

macOS

sudo lsof -nP -i :2497

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2497 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2497
netstat -ano | findstr :2497

From another machine

nmap -p 2497 -sV <host>
sudo nmap -sU -p 2497 <host>
nc -zv <host> 2497

Block it in the firewall

sudo ufw deny 2497/tcp                                         # Linux (ufw)

04 FAQ
What is port 2497 used for?

Port 2497 is assigned by IANA to quaddb (Quad DB).

Is port 2497 TCP or UDP?

Port 2497 is registered for TCP and UDP.

Is it safe to open port 2497?

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 2497 is open?

On Linux run "ss -ltnup 'sport = :2497'", on macOS "lsof -nP -i :2497", and on Windows "netstat -ano | findstr :2497" to see the local process. From another machine, "nmap -p 2497 <host>" shows whether it is reachable.
