Guide to using Nmap to scan for the Heartbleed bug.

Requirements

  1. Nmap. The script requires version 6.25 or newer. The latest version, 6.47, already includes the next 3 dependencies, so you can skip directly to the Scanning section below.
    • An easy way to get the latest Nmap release is to use Kali Linux.
    • Binary installers are available for Windows.
    • RPM installer available for Linux, or install from source.
    • .dmg installer available for Mac OS X.
  2. tls.lua. The script requires this Lua library for TLS handshaking.
  3. ssl-heartbleed.nse. This is the script itself.

Simply a collection of bash functions/scripts that I don't particularly have a practical use for, but decided to make them since I was bored anyway. Feel free to put them in your bash_aliases file.
#!/bin/bash
function package-version {
apt-cache policy $1 | grep Installed | awk -F ' ' '{print $2}'
}
function kernel-current-version {
major=$(uname -r | awk -F '.' '{print $1}')
minor=$(uname -r | awk -F '.' '{print $2}')
if [ $(uname -r | grep rc) ]; then
rc="rc$(uname -r | awk -F '-' '{print $2}' | awk -F 'rc' '{print $2}')"

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

Tmux, copy-mode, and OSX shenanigans.

Copy, with line wrapping!

If you've been trying to copy/paste text from a multi-pane tmux session with the mouse, you've probably been pretty pissed at the blissful ignorance a terminal application has of the rodent in your hand.

The alternative, which is quote-unqoute native copy/pasting using copy-mode takes a bit to get used to. So this is one solution for copying and pasting lines from a session with correct line wrapping behaviour, albeit keyboard only.

Disclaimer

Since copy-mode has similar concepts of marks, regions, and temp buffers to Emacs .. you'll probably find it straight forward if you're familar with Emacsen. For people using vi-mode in tmux, the same still applies but obviously the default key bindings will differ alot from what I show below.

Try to scrape formula information from @formula.homepage.

# Too bad no packaging microformat has yet been invented, but brew-more just first looks for a
