I just realized that the Mac OS X Kernel reached version 10.0.0 (aka X) with Snow Leopard.

Darwin Fast.local 10.0.0 Darwin Kernel Version 10.0.0: Fri Jul 31 22:46:25 PDT 2009; root:xnu-1456.1.25~1/RELEASE_X86_64 x86_64

Enable SSH Agent (Key) Forwarding on Snow Leopard

I’m using Git and Capistrano to deploy some ruby applications on multiple servers. My Git setup is done with gitosis which uses a key based authentication over ssh. The deployment script logs into the remote servers and checks out the current application version via Git.

Now to have this working, one must forward the private key, used to authenticate with git, to the server which does the checkout. This is done by the ssh-agent process, which whom you can register your keys by running the command ssh-add.

After switching to Snow Leopard, my deployment script stopped working, because somehow the ssh key didn’t get forwarded to the server and I was presented with a login prompt: “Enter password for git@git.gitserver.local:”. Of course I don’t have a password, because gitosis uses key based authentication only.

To make a long story short, Snow Leopard ships with key forwarding disabled by default and you will have to modify the file /etc/ssh_config to get it working.

Just change the lines

# Host *
# ForwardAgent no

into

Host *
ForwardAgent yes

and you are good.

First get and install the 64bit MySQL version:

Then install the MySQL gem the following way:

sudo gem install mysql — –with-mysql-config=/usr/local/mysql/bin/mysql_config
