Multiple SSH Keys settings for different github account
=================================================================
create different public key
---------------------------------
create different ssh key according the article [Mac Set-Up Git](http://help.github.com/mac-set-up-git/)
$ ssh-keygen -t rsa -C "your_email@youremail.com"
Please refer to [github ssh issues](http://help.github.com/ssh-issues/) for common problems.
for example, 2 keys created at:
~/.ssh/id_rsa_activehacker
~/.ssh/id_rsa_jexchan
then, add these two keys as following
$ ssh-add ~/.ssh/id_rsa_activehacker
$ ssh-add ~/.ssh/id_rsa_jexchan
you can delete all cached keys before
$ ssh-add -D
finally, you can check your saved keys
$ ssh-add -l
Modify the ssh config
---------------------------------
$ cd ~/.ssh/
$ touch config
$ subl -a config
Then added
#activehacker account
Host github.com-activehacker
HostName github.com
User git
IdentityFile ~/.ssh/id_rsa_activehacker
#jexchan account
Host github.com-jexchan
HostName github.com
User git
IdentityFile ~/.ssh/id_rsa_jexchan
Clone you repo and modify your Git config
---------------------------------------------
clone your repo
git clone git@github.com:activehacker/gfs.git gfs_jexchan
cd gfs_jexchan and modify git config
$ git config user.name "jexchan"
$ git config user.email "jexchan@gmail.com"
$ git config user.name "activehacker"
$ git config user.email "jexlab@gmail.com"
or you can have global git config
