ProxMox Cluster - Soup-to-Nutz

aka what i did to get from nothing to done.

note: these are designed to be primarily a re-install guide for myself (writing things down helps me memorize the knowledge), as such don't take any of this on blind faith - some areas are well tested and the docs are very robust, some items, less so). YMMV

Adding an audit log to your Rails app

If you have any sort of administrative interface on your web site, you can easily imagine an intruder gaining access and mucking about. How do you know the extent of the damage? Adding an audit log to your app is one quick solution. An audit log should record a few things:

controller entry points with parameter values
permanent information about the user, like user_id
transient information about the user, like IP and user_agent

Using the Rails framework, this is as simple as adding a before_action to your admin controllers. Here’s a basic version that I’m using in production.

	javascript:(function() {

	function copyToClipboard(text) {
	if (window.clipboardData && window.clipboardData.setData) {
	/IE specific code path to prevent textarea being shown while dialog is visible./
	return clipboardData.setData("Text", text);

	} else if (document.queryCommandSupported && document.queryCommandSupported("copy")) {
	var textarea = document.createElement("textarea");
	textarea.textContent = text;
