<p>The cakelampvm project provides a Virtualbox VM that acts as an "internet
in a bottle", serving up your web sites securely and only to your local
host. The virtual machine provides DNS services (<a target="_blank"
<pre><span style="font-weight: bold;">passwd</span></pre>
The 'passwd' command will ask for your current password, and then for a
new password plus a verification of that new password.<br>
+ You will probably want to change your samba password as well, which is
+ used when accessing the virtual machine over the network. This is
+ a different, but very similar, command on Linux:<br>
+ <pre><span style="font-weight: bold;">smbpasswd</span></pre>
</li>
<li>Change your git configuration for the user and email address.
This is how we've configured it so far:<br>
<h4>Setting up DNS on Windows<a id="#windoze-dns" name="#windoze-dns"></a></h4>
<p>The ipconfig tool will provide helpful information about your current
networking and DNS configuration:</p>
- <pre>> ipconfig /all</pre>
+ <pre><span style="font-weight: bold;">> ipconfig /all</span></pre>
<p>The DNS configuration on Windows is somewhat byzantine. The pipe
characters ('|') below are used to separate the menus or tabs or dialogs
to traverse. Follow this path to get to the DNS config:</p>
settings on your Host PC are right, then you may need to flush your DNS
cache, and that might be sufficient to start getting the right IP
address. On Windows, the command for flushing DNS is:</p>
- <pre>> ipconfig /flushdns</pre>
+ <pre><span style="font-weight: bold;">> ipconfig /flushdns</span></pre>
<p>and on Linux the flush DNS command can be many different things, but try
these two most common options:</p>
<pre><span style="font-weight: bold;"># restarts the client side DNS cache.<br>sudo service dns-clean restart</span></pre>
