01 Security

Is port 1114 dangerous?

We have no specific security note for port 1114. 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 1114, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1114'      # process listening on 1114
sudo lsof -nP -i :1114

macOS

sudo lsof -nP -i :1114

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1114 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1114
netstat -ano | findstr :1114

From another machine

nmap -p 1114 -sV <host>
sudo nmap -sU -p 1114 <host>
nc -zv <host> 1114

Block it in the firewall

sudo ufw deny 1114/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1114" -Direction Inbound -LocalPort 1114 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1114 used for?

Port 1114 is assigned by IANA to mini-sql (Mini SQL).

Is port 1114 TCP or UDP?

Port 1114 is registered for TCP and UDP.

Is it safe to open port 1114?

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 1114 is open?

On Linux run "ss -ltnup 'sport = :1114'", on macOS "lsof -nP -i :1114", and on Windows "netstat -ano | findstr :1114" to see the local process. From another machine, "nmap -p 1114 <host>" shows whether it is reachable.
