oanhnn

Problem

I have two Github accounts: oanhnn (personal) and superman (for work). I want to use both accounts on same computer (without typing password everytime, when doing git push or pull).

Solution

Use ssh keys and define host aliases in ssh config file (each alias for an account).

How to?

1. Generate ssh key pairs for accounts and add them to GitHub accounts.

# the admin password for all of the IE VMs is “Password1″ without the quotes, it's also used for the password hints

1) Install VirtuaBox on your mac

http://download.virtualbox.org/virtualbox/4.1.10/VirtualBox-4.1.10-76795-OSX.dmg

2) Decide which versions of Internet Explorer you want to download and install – each version of Internet Explorer is contained within a separate virtual machine that runs within VirtualBox. In other words, if you want to run Internet Explorer 7, 8, and 9, you will need to download three separate VM’s, which may take a while so keep that in mind. Select the text below and copy it:

# Install ALL versions of Internet Explorer: IE 7, IE 8, and IE 9 (for now this script will also pull down a IE 6 vm with windows xp)
