Gitolite and SSH

gitolite and ssh

I have installed gitolite (v3) on server (host.name.com).

SSH Information

I have a private key, ~/.ssh/ida_rsa_gitolite, in lab.  I have already added my public key to gitolite.  I also have an ssh configuration file in ~/.ssh/config file in lab.

mvelez@lab:~/.ssh$ cat config

host gitolite

user git

hostname host.name.com

identityfile ~/.ssh/id_rsa_gitolite

I can use the 'gitolite' alias.

mvelez@lab:~$ ssh -T gitolite
hello mvelez, this is git@server running gitolite3 v3.03-29-g3c0f177 on git 1.7.9.5


 R W gitolite-admin
 R W testing

And I can use git@host.name.com directly.

mvelez@lab:~$ ssh -T git@host.name.com
hello mvelez, this is git@server running gitolite3 v3.03-29-g3c0f177 on git 1.7.9.5


 R W gitolite-admin
 R W testing

What I really care about is being able to do this.

mvelez@eden:~$ git clone git@host.name.com:gitolite-admin

Questions:  

1) Do I have to run 'ssh-add ~/.ssh/id_rsa_gitolite'?

RubyCLI: A Ruby Command Line Application Module

Download ruby_cli, a Ruby gem I wrote to help create Ruby command line interface programs.

Here is an example program which uses ruby_cli.

 #!/usr/bin/ruby  
 require 'rubygems'  
 require 'ruby_cli'  
 class App  
  include RubyCLI  
  def command  
   puts "Hello World"  
  end  
 end  
 app = App.new(ARGV, __FILE__)  
 app.run    

Running the program:

Connect to MySQL via SSH Tunnel

I have set up a MySQL server and want to connect to it from different machines.  However, I do not want to open it up to the public.  To secure my connection, I will not allow external connections to the MySQL server.  I will simply set up a SSH tunnel and connect to it that way.  My local MySQL commands are forwarded to the remote host.

Assumptions:

1. You can SSH into the remote host.
2. If you are like me, you are not running a MySQL on your local host.

Setting up the SSH tunnel:

1. ssh -f -L 3306:localhost:3306 user@host -N
2. Enter password:

Connect to MySQL

1. mysql -h 127.0.0.1 -u user -p
2. Enter password:

You should be see the MySQL prompt.
