tmux shortcuts & cheatsheet

start new:

tmux

start new with session name:

tmux new -s myname

I use tmux splits (panes). Inside one of these panes there's a Vim process, and it has its own splits (windows).

In Vim I have key bindings C-h/j/k/l set to switch windows in the given direction. (Vim default mappings for windows switching are the same, but prefixed with C-W.) I'd like to use the same keystrokes for switching tmux panes.

An extra goal that I've solved with a dirty hack is to toggle between last active panes with C-\.

Here's how it should work:

Overview

This gist provides a quick overview of deploying SSL certificates to servers using Salt. I use a wildcard certificate for our domain, which makes management easier.

Quick Start

Start with pillar_ssl-certificate.sls, which should be populated with your certificates and placed in Salt's pillar_roots directory (typically /srv/pillar).
Place state_ssl-certificate.sls in Salt's file_roots directory (typically /srv/salt).
Include the contents of top.sls in both the pillar and state top.sls file. (Modify for your minion IDs of course.)

Details

Use pillars to distribute sensitive data, such as SSL certificates. Accoring to the [Salt Pillar Walkthrough][2]:

Information transferred via pillar is guaranteed to only be presented to the minions that are targeted, making Pillar suitable for managing security information, such as cryptographic keys and passwords.
