A Capistrano Rails Guide

by Jonathan Rochkind, http://bibwild.wordpress.com

why cap?

Capistrano automates pushing out a new version of your application to a deployment location.

I've been writing and deploying Rails apps for a while, but I avoided using Capistrano until recently. I've got a pretty simple one-host deployment, and even though everyone said Capistrano was great, every time I tried to get started I just got snowed under not being able to figure out exactly what I wanted to do, and figured I wasn't having that much trouble doing it "manually".

# Jabber-SH — SH console via XMPP/Jabber (GTalk)
#
# Jabber-SH allows you to administrate a remote computer via a command line 
# through a Jabber client. It’s like SSH via GoogleTalk! :)
# This is just a hack but it might be usefull sometime to run basic commands
# on a machine that is not accessible via ssh.

Introduction

ssh-srv-wrapper is bash shell script which tries to find a SSH SRV record for the first host and uses what is found rather than what was passed (if a valid record is found).

Install

Run the script directly or feel free to rename or symlink to the name ssh. It will look for another ssh in your path to execute.
