I used AI. It worked. I hated it. I used Claude Code to build a tool I needed. It worked great, but I was miserable. I need to reckon with what it means.

As a research project, I built a needed tool with Claude Code. I though it would be a disaster, but It wasn't. I have some complicated feelings about it.

Name them
shame them

Thx <3

This leads to 404 page :/

This is funny because people use ai to generate headshots from selfies and then another ai is used to assess the facial expressions of said image 🫣😬

A mushroom with a huge hat, is growing on a tree. It looks like it has a face and a pice on the side looks like a hand, giving the impression of the mushroom smiling and winking.

Welcome to Cisco 🫣 always a good experience when they are involved

Welcome to Cisco 🫣 always a good experience when they are involved

Take care dude! We need you for a hundred years more!

Love it! There is an issue with the email field though, made it hard(er) to sign up

How do you do so many things at once btw? :D I feel like every month you publish a banger new project

Is this by any chance an online class one could sit in next time you teach it?

+1 😬

WOHOOOOO IT WORKED WE ARE MAGICIANS! 🪄🦄

Well done friends, in the next post we shall do the same on multiple machines at the same time 💜

Cant wait to talk to you again!

ansible -i ./hosts.yml infrastructure -a "ping 192.168.188.1 -c 1" - output in an ubuntu terminal

It has an associated IP address, a username that should be used for the ssh connection and the private key needed to initiate the connection

with that out of the way we can run the command from earlier:

ansible -i hosts.yml infrastructure -a 'ping 192.168.188.1 -c 1'

What do we see here?!

First all the machines are collected by a self-defined metagroup - “infrastructure”.

now a list of all the hosts inside this group follows, in this example we will only have one for now - debian

content of the hosts.yml file showing an infrastructure group with one host - debian and associated parameters - IP address, ansible user, and the ssh key ansible should use

WAIT - STOP - HOLD ON

what is inside the hosts.yml and what is a yml in the first place?

a .yml file is a yaml (Yet Another Markup Language) file

but how do we execute the commands now?

you use ansible 💜

like so:

ansible -i hosts.yml infrastructure -a 'ping 192.168.188.1 -c 1'

cat authorized_keys on a debian machine showing only one ssh key from a ubuntu machine

fear not - that is totally expected - your key is well “hidden” in the authorized keys - open that one and find out:

aha - ok that looks like the correct key with the correct username at the end 😌

contents of the folder .ssh shown, only one file visible - authorized_keys

GREAT!

can we check if the key is really there?

sure!

but um… this does not look like it is there?

"ssh-copy-id -i .ssh/ansible-debian debian@debian" running in a ubuntu terminal

you type:

ssh-copy-id -i <location_of_your_ssh_key> username@controlled-machine

press enter and then you need to enter the password for the controlled-machine user

if all goes well you see something similar to the following image:

wonderful - now two options exist

1. you copy the public ssh key to the machine via copy/paste

2. you use ssh-copy-id

We shall use 2. today, because it is freaking cool!

ssh-keygen -b 4096

now generate a private key on your host machine with

ssh-keygen -b 4096

make sure to enter the correct location and add a passkey if you care about security 🙏

if you are lucky it is already running - if not install it via:

sudo apt-get install openssh-server

output of "systemctl status ssh" in a terminal on a debian machine showing the ssh server is running

cool cool cool - what now?

now you need to identify how you can connect to the controlled machine - e.g. via ssh if it is linux

that means ssh needs to run on the controlled machine - check via:

systemctl status ssh

terminal output after finished ansible installation showing all went well

smash that y button and the enter key right afterwards

and then wait until the install is finished ⏳ → ⌛️

output of "sudo apt-get install ansible"

First, install ansible on your host machine via:

sudo apt-get install ansible

(if your host is debian/ubuntu based)

and the best part?


you do _NOT_ have to install it on the client systems, only on your host / the controlling node!


Ok great, but how do we start ➡️ 🏁
