										 |  |  | PASSWORDLESS CONNECTIONS | 
					
						
							|  |  |  | ------------------------ | 
					
						
							|  |  |  | It is recommended to run cdist with public key authentication. | 
					
						
							|  |  |  | This requires a private/public key pair and the entry | 
					
						
							|  |  |  | "PermitRootLogin without-password" in the sshd server. | 
					
						
							|  |  |  | See sshd_config(5) and ssh-keygen(1). | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | SPEEDING UP SSH CONNECTIONS | 
					
						
							|  |  |  | --------------------------- | 
					
						
							|  |  |  | When connecting to a new host, the initial delay with ssh connections | 
					
						
							|  |  |  | is pretty big. You can work around this by | 
					
						
							|  |  |  | "sharing of multiple sessions over a single network connection" | 
					
						
							|  |  |  | (quote from ssh_config(5)). The following code is suitable for | 
					
						
							|  |  |  | inclusion into your ~/.ssh/config: | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | -------------------------------------------------------------------------------- | 
					
						
							|  |  |  | Host * | 
					
						
							|  |  |  |   ControlPath ~/.ssh/master-%l-%r@%h:%p | 
					
						
							|  |  |  |   ControlMaster auto | 
					
						
							|  |  |  |   ControlPersist 10 | 
					
						
							|  |  |  | -------------------------------------------------------------------------------- |

										 |  |  | MULTI MASTER OR ENVIRONMENT SETUPS | 
					
						
							|  |  |  | ---------------------------------- | 
					
						
							|  |  |  | If you plan to distribute cdist among servers or use different | 
					
						
							|  |  |  | environments, you can do so easily with the included version | 
					
						
							|  |  |  | control git. For instance if you plan to use the typical three | 
					
						
							|  |  |  | environments production, integration and development, you can | 
					
						
							|  |  |  | realise this with git branches: | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | -------------------------------------------------------------------------------- | 
					
						
							|  |  |  | # Go to cdist checkout | 
					
						
							|  |  |  | cd /path/to/cdist | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | # Create branches | 
					
						
							|  |  |  | git branch development | 
					
						
							|  |  |  | git branch integration | 
					
						
							|  |  |  | git branch production | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | # Make use of a branch, for instance production | 
					
						
							|  |  |  | git checkout production | 
					
						
							|  |  |  | -------------------------------------------------------------------------------- | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Similar if you want to have cdist checked out at multiple machines, | 
					
						
							|  |  |  | you can clone it multiple times: | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | -------------------------------------------------------------------------------- | 
					
						
							|  |  |  | machine-a % git clone git://your-git-server/cdist | 
					
						
							|  |  |  | machine-b % git clone git://your-git-server/cdist | 
					
						
							|  |  |  | -------------------------------------------------------------------------------- | 
					
						
							|  |  |  |
