This example shows how to replace the Cisco AnyConnect client on Mac OS X with the OpenConnect command-line tool, emphasizing steps to install it via Homebrew, configure password-less sudo, and handle self-signed certificates by exporting them from Keychain. The write-up uses OpenConnect’s `--user` and `--cafile` flags for VPN authentication, referencing the `sudo visudo` configuration and the TUN/TAP driver. It also notes a potential DNS resolution issue after unclean disconnects. The visualization relies on text commands and screenshots, not data or rendering libraries.

OpenConnect VPN on Mac OS X

This example presents a step-by-step technical guide for configuring OpenConnect, a command-line client for Cisco's AnyConnect SSL VPN, on Mac OS X. It shows how to install the client via Homebrew, install the TUN/TAP driver, and optionally configure password-less sudo for the openconnect command. The guide also explains how to handle self-signed certificates by exporting a .pem file from the Keychain Access app and passing it via the --cafile flag. The final command connects using sudo openconnect with the user, certificate, and VPN hostname.

Fix for OpenVPN/ Tunnelblick: `Can't assign requested address`

This example visualizes the network interface state changes prescribed by a shell script that fixes OpenVPN/Tunnelblick’s “Can’t assign requested address” error. The visualization shows the sequence of `sudo ifconfig en1 down`, `route flush`, and `ifconfig en1 up` commands as a flow diagram, using the script’s raw text as its data source. It renders the command arguments as labeled nodes connected by arrows, with the network interface (`en1`) highlighted as the primary target. The code relies on `d3.forceSimulation` for node positioning and `d3.select` with `attr` and `text` methods to draw the graph, directly mapping the script’s lines to visual elements.

Gist 2d49cdee90acfeaa8195

This example is a plain-text setup guide for configuring a fresh Mac OS X 10.10 Yosemite installation, listing software to install from the App Store and third-party sources, and providing shell commands for tools like Homebrew and Cask. The document shows the step-by-step process of installing developer tools, applications, and system preferences, with links to each software package. It references the Homebrew package manager and the Cask extension for command-line installation, alongside manual downloads for browsers and utilities. The data is presented as a structured checklist rather than a visualization, relying on markdown formatting for organization.

OSX - Installs

This visualization maps the installation steps for setting up a macOS development environment, showing a sequential workflow from Homebrew installation through Oh My Zsh, Oh My Posh, and the CopyClip cask. The code uses a Bash script with `curl` commands to fetch remote install scripts and the `brew install` command for package management. The display likely uses a node-link diagram rendered with D3.js’s `d3.forceSimulation` to position each command as a node, with edges indicating the order of execution. The data source is a raw gist file containing the terminal commands, visualized as a directed graph to illustrate dependencies between installation actions.

Cracking WPA2 / WEP Wifi / Aircrack 10 seconds guide. For Mac OSX

This example visualizes a terminal-based workflow for cracking WPA2/WEP WiFi networks using Aircrack-ng on macOS, showing the step-by-step command sequence from installation to packet capture. The code relies on the `airport` command from Apple’s private frameworks (via a symlink), `aircrack-ng` for decryption, and shell operations like `sudo port install` and `airport sniff` to capture traffic. It highlights the concrete API calls—`airport -s` for channel scanning and `aircrack-ng -1 -a 1 -b` for target cracking—while the raw command output (e.g., `[CHANNEL]`, `[TARGET_MAC_ADDRESS]`, and the `/tmp/airportSniff*.cap` file path) serves as the data source. The visualization renders as a textual command list, not a graphical chart, emphasizing the procedural logic over spatial encoding.

Gist 5c4aad6bd3947d114e739c67638c219e

This example demonstrates how to set up an SSH connection from a ChromeBook or Chrome OS device to a server using RSA key authentication. It shows the server-side key generation process with `ssh-keygen`, the manual transfer of the private key to the ChromeBook’s download directory, and the step-by-step crosh shell commands (`ssh`, `host`, `user`, `key`, `connect`) needed to establish the session. The content also includes a direct macOS terminal command (`ssh <username>@<host> -i <key file path>`) as an alternative login method, with notes on the roles of `authorized_keys` and `known_hosts` files.

Homebrew: Permissions Denied Issue Fix (OS X / macOS)

This example shows a single command for fixing Homebrew “Permission Denied” errors on macOS, displayed as a code snippet in a Markdown document. The visualization highlights the exact shell command using `sudo chown -R` to recursively change file ownership under the Homebrew prefix. It relies on the `$(whoami)` and `$(brew --prefix)` command substitutions to target the current user and Homebrew installation path. The code is presented as plain text within the gist’s Markdown file, with no interactive or graphical elements.

SSH Brew Setup

This example visualizes the SSHpass formula setup process, showing the sequence of build and installation steps for a Homebrew package. The visualization uses a direct graph representation, where nodes correspond to the formula’s Ruby methods (`install`, `test`, and the implicit `require`), and edges depict the control flow from the formula class definition to the system commands. The data source is the Ruby source file `sshpass.rb`, which contains the formula’s URL, SHA256 checksum, and custom build logic. The rendering relies on a custom layout algorithm, likely using D3’s force simulation to position nodes and SVG paths for the edges, highlighting the dependency between the configuration script and the `make install` step.
