Using Lima’s Fedora VM + NCDU

 

Intro Cockpit 20231218 102441 2

Once the VM has been installed and executed the bash scripts, it is time to fire up Cockpit.

Note While a Lima-based Cockpit is accessed via port 9090, in an ideal world any and all Cockpits configured on your server whether they be on the metal or in a VM should be accessed via SSH – usually on port 22.

Getting started with Cockpit

In addition Lima does not allow a public accessible IPv6 address. If you are trying to reach your IPv6 SHES server from a remote location, you will either need to have a computer running Linux with Cockpit on the metal or in a VM (like a MBA) OR use a VNC client app that allows you to connect to a remote VNC server via SSH assuming the server has an open port 22 and an accessible IPv6 address.

To access Cockpit running on the Mac you are using without bridge mode point your browser to https://locahost. Or – in bridge mode – https://local-ip-address. If you are intending to access Cockpit on another local Mac which is in bridged mode that you presumably are connected to via SSH, enter the VM’s shell and enter the ip address command to retrieve the IP address as follows:

$ ssh user@vm-host
vm-host $limactl shell vm-name
vm-host vm-name $ ip address show lima0

Uploading is simple with Cockpit.

BTW many (but not all) of these utilities can also be installed directly in MacOS with are old friend Brew. Let’s look up ncdu on Brew. First of all what is ncdu? Just ask The Fedora…

As a result of the apex powers at Apple, ncduwould actually be a useful utility for the Mac. Let’s go to https://brew.io and see if it is available and how to install it. Enter ncdu in Brew’s Search box.

Brew will respond with a list of packages that match the search criteria. Click on it ncdu

Brew will provide all the information required to get started with installing and using ncdu.

Let’s go ahead and install it on the Mac and give it a try…
