01 Security

Is port 1754 dangerous?

We have no specific security note for port 1754. 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 1754, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1754'      # process listening on 1754
sudo lsof -nP -i :1754

macOS

sudo lsof -nP -i :1754

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1754 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1754
netstat -ano | findstr :1754

From another machine

nmap -p 1754 -sV <host>
sudo nmap -sU -p 1754 <host>
nc -zv <host> 1754

Block it in the firewall

sudo ufw deny 1754/tcp                                         # Linux (ufw)

04 FAQ
What is port 1754 used for?

Port 1754 is assigned by IANA to oracle-em2 (oracle-em2).

Is port 1754 TCP or UDP?

Port 1754 is registered for TCP and UDP.

Is it safe to open port 1754?

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 1754 is open?

On Linux run "ss -ltnup 'sport = :1754'", on macOS "lsof -nP -i :1754", and on Windows "netstat -ano | findstr :1754" to see the local process. From another machine, "nmap -p 1754 <host>" shows whether it is reachable.
