<div class="sectionbody">
<div class="paragraph"><p>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).</p></div>

<div class="sectionbody">
<div class="paragraph"><p>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:</p></div>
<div class="listingblock">

<h2 id="_multi_master_or_environment_setups">MULTI MASTER OR ENVIRONMENT SETUPS</h2>
<div class="sectionbody">
<div class="paragraph"><p>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:</p></div>
<div class="listingblock">
<div class="content">
<pre><tt># 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</tt></pre>
</div></div>

you can clone it multiple times:</p></div>
