01 Security

Is port 7794 dangerous?

We have no specific security note for port 7794. Its risk depends on the program actually listening on it. General advice for devops, cloud & containers services:

  • Container and orchestration APIs give full control of hosts: require mutual TLS and RBAC.
  • Never expose them to the Internet.
  • Rotate tokens and certificates and audit who has access.

03 Check it

Which program uses port 7794, and is it reachable?

Linux

sudo ss -ltnup 'sport = :7794'      # process listening on 7794
sudo lsof -nP -i :7794

macOS

sudo lsof -nP -i :7794

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 7794 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 7794
netstat -ano | findstr :7794

From another machine

nmap -p 7794 -sV <host>
sudo nmap -sU -p 7794 <host>
nc -zv <host> 7794

Block it in the firewall

sudo ufw deny 7794/tcp                                         # Linux (ufw)

04 FAQ
What is port 7794 used for?

Port 7794 is assigned by IANA to q3ade (Q3ADE Cluster Service).

Is port 7794 TCP or UDP?

Port 7794 is registered for TCP and UDP.

Is it safe to open port 7794?

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. Container and orchestration APIs give full control of hosts: require mutual TLS and RBAC.

How do I check if port 7794 is open?

On Linux run "ss -ltnup 'sport = :7794'", on macOS "lsof -nP -i :7794", and on Windows "netstat -ano | findstr :7794" to see the local process. From another machine, "nmap -p 7794 <host>" shows whether it is reachable.
