<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"

<h2>Starting up the VM and Connecting to It<a id="#start-vm" name="#start-vm"></a></h2>
is generally more useful to connect to the cakelampvm over ssh. If the
networking has been established properly, you should be able to do this
with:
- <pre># ssh developer@10.28.42.20 # or the equivalent with your ssh client</pre>
+ <pre><span style="font-weight: bold;">ssh developer@10.28.42.20<br># or perform the equivalent connection with your ssh client.</span></pre>
<p>And then provide the password to log in.</p>
<p>Once the DNS services are set up (discussed in detail below), you will be
able to run the much friendlier command:</p>
- <pre># ssh developer@cakelampvm.com</pre>
+ <pre><span style="font-weight: bold;">ssh developer@cakelampvm.com</span></pre>
<h4>Key Forwarding to the VM</h4>
<p>It is important to set up ssh key forwarding to enable your use of git
repositories while logged into the VM. Key forwarding should be
enabled for the VM's two fake host identities:</p>
- <pre>cakelampvm.com<br>10.28.42.20</pre>
+ <pre><span style="font-weight: bold;">cakelampvm.com<br>10.28.42.20</span></pre>
<h2>Updating cakelampvm to the Latest Model<a id="#update-vm" name="#update-vm"></a></h2>
<p>The cakelampvm v002 is released with the intention that it not need to be
released again. Version 001 was not built with that explicit
<p>There is an update feature built into the VM that is quite easy to
use. The updates are driven by the feisty meow script repository in
conjunction with a local scripted command. To activate the "update
- process" for your VM, run the following commands on the VM (without the
- initial '#' symbol):</p>
- <pre># rpuffer $FEISTY_MEOW_APEX # updates to the latest version of feisty meow
-# revamp_cakelampvm # enacts any configuration changes needed,<br> # plus fixes web folder and other permissions.</pre>
+ process" for your VM, run the following commands on the VM:</p>
+ <pre><span style="font-weight: bold;"># update to the latest version of feisty meow.<br>rpuffer $FEISTY_MEOW_APEX; reconfigure_feisty_meow<br># enact any configuration changes needed, such as permissions and account setup.
+revamp_cakelampvm</span></pre>
+ <span style="font-weight: bold;"> </span>
<p>These two commands can be run at any time to patch up your VM to the
latest.</p>
- <p>The first command ("rpuffer ...") is also useful on its own for getting
- the latest version of the feisty meow code. Run it again if there
- are bug fixes you need for any of the scripts or if you would like the
- most up-to-date cakelampvm documentation.</p>
+ <p>Recent versions of feisty meow support a new "<span style="font-weight: bold; font-family: monospace;">get_feisty</span>"
+ command, which will behave the same as the first line above. Once
+ you have run the "puffer..." command above for the first time (on
+ cakelampvm v002), this new command becomes available.</p>
+ <ul>
+ <li>The "<span style="font-weight: bold; font-family: monospace;">get_feisty</span>"
+ command is useful in its own right for getting the latest version of the
+ feisty meow code; run it again if you need bug fixes or if you want the
+ most recent cakelampvm documentation.</li>
+ <li>The "<span style="font-weight: bold; font-family: monospace;">revamp_cakelampvm</span>"
+ command can be used to repair many situations when the cakelampvm has
+ gone astray, especially for problems with permissions.</li>
+ </ul>
<h2>First Tasks as the Developer User</h2>
<p>Here are some first steps that will make the vm your own:</p>
<ol>
<li>Change your password for the developer account. (This may
eventually be required and automatic.) First, log into the VM with
ssh. Then type this command:<br>
- <pre># passwd</pre>
+ <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>
- <pre># git config --global user.email "developer@cakelampvm.com"</pre>
- <pre># git config --global user.name "Developer J. Cakemo"</pre>
+ <ul>
+ <li>
+ <pre><span style="font-weight: bold;">git config --global user.email "developer@cakelampvm.com"</span></pre>
+ </li>
+ <li>
+ <pre><span style="font-weight: bold;">git config --global user.name "Developer J. Cakemo"</span></pre>
+ </li>
+ </ul>
If you're developing on a real project, you probably don't want the
bogus email and even more bogus name above attached to your
commits. Just run the two commands again but with proper values.</li>
meow command reference</a> file.</p>
<p>(The feisty meow codebase is already configured for the developer account
on the cakelampvm virtual machine.)</p>
- <h2>X11 applications launched from the VM</h2>
- <p>[incomplete section]</p>
- <p>If a feature called "X forwarding" is enabled in your ssh client, then
- you can start graphical applications on the VM and display them on your
- local machine. This works right away on most Linux hosts, but can
- also work on PCs with X window system installed. This section
- describes how to set up Cygwin to run X server, which enables X11
- forwarding to your local display.</p>
- <p>...{insert that info}...</p>
<h2>Using the guest VM's DNS services<a id="#dns-from-vm" name="#dns-from-vm"></a></h2>
<p>The cakelampvm has been set up to provide a DNS server which will answer
name lookup requests on any of the sites that the cakelampvm is hosting
10.28.42.20. (The DNS server can be tested with nslookup, dig and
other tools.)</p>
<p>Note that the cakelampvm DNS should be listed first, if one intends to
- override any DNS names that actually exist out on the internet. Further,
- we have found it most effective to have *only* the cakelampvm as your DNS
- server, because a secondary DNS server can "take over" providing the name
- lookups, and thus foul up DNS requests that should succeed for your
- VM-hosted sites.</p>

<p>If your Host PC is running Windows, see the DNS configuration section
below that is tailored to that operating system.</p>
<p>Important Note: It behooves you to remember to switch back to a normal
both the cakelampvm VM and on your host PC. Note: ping on Linux
keeps going forever, so hit control-C when you are tired of seeing the
pings:</p>
- <pre># ping cakelampvm.com</pre>
- <pre># ping mapsdemo.cakelampvm.com</pre>
+ <pre><span style="font-weight: bold;">ping cakelampvm.com</span></pre>
+ <span style="font-weight: bold;"> </span>
+ <pre><span style="font-weight: bold;">ping www.cakelampvm.com</span></pre>
<p>Note that any other answer than 10.28.42.20 for the address is *bzzzt*
wrong, and means something needs to be fixed.</p>
<p>If these pings succeed (which hopefully they will!), then try accessing
<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># sudo service dns-clean restart # restarts the client side DNS cache.</pre>
+ <pre><span style="font-weight: bold;"># restarts the client side DNS cache.<br>sudo service dns-clean restart</span></pre>
<p>or</p>
- <pre># sudo service nscd restart # restarts the nscd caching server.</pre>
+ <pre><span style="font-weight: bold;"># restarts the nscd caching server.<br>sudo service nscd restart</span></pre>
After, this try the pings again. If they still fail, please go back
over your DNS configuration very carefully. The cakelampvm's DNS
feature *does* actually work, but operating systems sometimes do their best
<p>If you run into any permission problems that prevent file access, either
remotely or within the VM itself, then try running this command to fix
them (repeated from the section above about updating the cakelampvm):</p>
- <pre># revamp_cakelampvm</pre>
+ <pre><span style="font-weight: bold;">revamp_cakelampvm</span></pre>

create new folders at will.</p>

shared, and give it a name for the guest. We assume the folder
name will be "myshare".</li>
<li>On the guest vm, run the following commands to mount the share:<br>
- <pre># mkdir ~/shared # for the guest's version of the shared folder<br># sudo mount -t vboxsf myshare ~/shared # mount the vm's share name onto the folder on the vm.</pre>

<h2>Adding a new website and domain on the guest VM</h2>
<p>Note: these instructions, even the quick approaches below, pale in
comparison to the ease of use of the "standup" command in feisty meow's
details on how to add a containing domain for the first time.
<h4>Quick approach: Use the feisty meow "add_domain" command.</h4>
<p>Run this command in a bash shell on the VM:</p>
- <pre># add_domain excalibur.cakelampvm.com</pre>
+ <pre><span style="font-weight: bold;">add_domain excalibur.cakelampvm.com</span></pre>
<p>Done.</p>
<h4>Manual approach: Edit the bind9 configuration.</h4>
<p>Note: the manual approach is not compatible with later use of feisty
meow's "remove_domain".</p>
Execute the following command to edit the DNS file for the cakelampvm
domain:
- <pre># sudo vi /etc/bind/cakelampvm.com.conf</pre>
+ <pre><span style="font-weight: bold;">sudo vi /etc/bind/cakelampvm.com.conf</span></pre>
<p>Add a stanza for the new site at the end of this file:</p>
<pre>excalibur.cakelampvm.com. IN A 10.28.42.20<br> IN HINFO "linux server" "ubuntu"</pre>
<p>Restart the DNS server:</p>
- <pre># sudo service bind9 restart</pre>
+ <pre><span style="font-weight: bold;">sudo service bind9 restart</span></pre>
<p>Afterwards, pinging excalibur.cakelampvm.com should work from both the
guest VM and the host PC.</p>
<h3>DNS Option B: Using an entirely new domain for the site</h3>
this example, we need to add the site "excalibur.tv" into the DNS.</p>
<h4>Quick approach: Use the feisty meow "add_domain" command.</h4>
Run this command in a bash shell on the VM:
- <pre># add_domain excalibur.tv</pre>
+ <pre><span style="font-weight: bold;">add_domain excalibur.tv</span></pre>
<p>Done.</p>
<h4>Manual approach: Edit a new DNS config file</h4>
<p>Note: the manual approach is not compatible with later use of feisty
to add the new file by adding this bit of configuration at the end:</p>
<pre>zone "excalibur.tv" in {<br> file "/etc/bind/excalibur.tv.conf";<br> type master;<br> allow-query { any; };<br>};</pre>
<p>Restart the DNS server:</p>
- <pre># sudo service bind9 restart</pre>
+ <pre><span style="font-weight: bold;">sudo service bind9 restart</span></pre>
<p>Afterwards, pinging excalibur.tv should work from both the guest and the
host.</p>
<h3>Creating a New Apache Site</h3>
developer@cakelampvm.com </p>
<h4>Quick approach: Use the feisty meow "add_apache_site" command.</h4>
<p>Run this command in a bash shell on the VM:</p>
- <pre># add_apache_site excalibur excalibur.tv</pre>
+ <pre><span style="font-weight: bold;">add_apache_site excalibur excalibur.tv</span></pre>
<p>(The first parameter is the application name, the second is the domain
name.)</p>
<p>Done.</p>
appropriate file name that includes the site's domain name. We will
call our config file "excalibur.tv.conf". If you developed the file
in your home folder, this would be the command to move it up to Apache:</p>
- <pre># sudo cp ~/excalibur.tv.conf /etc/apache2/sites-available</pre>
+ <pre><span style="font-weight: bold;">sudo cp ~/excalibur.tv.conf /etc/apache2/sites-available</span></pre>
<p>Then tell apache to use the new file:</p>
- <pre># sudo a2ensite excalibur.tv # the '.conf' portion of the filename is unnecessary for this command.
+ <pre><span style="font-weight: bold;">sudo a2ensite excalibur.tv<br># the '.conf' portion of the filename is unnecessary for this command.</span>
</pre>
<p>Finally, restart apache to get it to begin serving the site:</p>
- <pre># sudo service apache2 restart</pre>
+ <pre><span style="font-weight: bold;">sudo service apache2 restart</span></pre>
<h3>Test the new web site</h3>
<p>Given the configuration above, your host PC should now be able to access
the new website on the domain "excalibur.tv".</p>
<p>To test this, first try pinging the new DNS name:</p>
- <pre># ping excalibur.tv</pre>
- <p>If there are responses to the ping *and* the answer is 10.28.42.20, then
- it means the DNS is working. If there are no responses or it's some
- other IP address talking back, check the instructions in the above DNS
- sections.</p>
+ <pre><span style="font-weight: bold;">ping excalibur.tv</span></pre>
+ <p>If there are responses to the ping <span style="font-weight: bold;">*and*</span>
+ the answer is 10.28.42.20, then it means the DNS is working.</p>
+ <p>If there are no responses or it's some other IP address talking back,
+ check the instructions in the above DNS sections.</p>
<p>Once the DNS is working, try browsing to the site at "<a title="it's excalibur, wilbur!"
href="http://excalibur.tv">http://excalibur.tv</a>". That should
at least bring up the configured site storage path, even if nothing is

<h3>Using the "meld" Tool to Compare Files & Directories</h3>
<p>Meld is a great comparison tool that displays differences between two
files or directories or directory trees in a graphical view. Meld is
pre-installed on the VM. This tool can be launched either in the
VM's X Windowing System (on the console) or if X11 forwarding is enabled.</p>
<p>To run meld, just type this command:</p>
- <p>#meld A B</p>
- <p>where A and B are either both file names or they are both directory names.
- If A and B are directories, meld will compare the entire tree structure
- between the two directories. It allows one to copy from one side to
- the other, even if the item that needs to be copied is an entire
- subdirectory.</p>
+ <pre><span style="font-weight: bold;">meld A B</span></pre>
+ <p>where A and B are either both file names or they are both directory
+ names. If A and B are directories, meld will compare the entire tree
+ structure between the two directories. It allows one to copy from
+ one side to the other, even if the item that needs to be copied is an
+ entire subdirectory.</p>
<h3>Get the network address on the guest vm</h3>
<p>Run this command:</p>
- <pre># ifconfig</pre>
+ <pre><span style="font-weight: bold;">ifconfig</span></pre>
<p>In the results, look for "<span style="font-family: monospace;">inet addr</span>".
There may be more than one, if there are multiple network interfaces.</p>
<p>The standard IP address is 10.28.42.20 for the cakelampvm.</p>
<p>When you've got the DNS and everything integrated, these commands will
manage the vm's state:</p>
<p>First, log into the guest VM:</p>
- <pre># ssh developer@cakelampvm.com</pre>
+ <pre><span style="font-weight: bold;">ssh developer@cakelampvm.com</span></pre>
<p>Then, to reboot the guest VM:</p>
- <pre># sudo reboot</pre>
+ <pre><span style="font-weight: bold;">sudo reboot</span></pre>
<p>Or, to halt the guest VM:</p>
- <pre># sudo shutdown -h now</pre>
+ <pre><span style="font-weight: bold;">sudo shutdown -h now</span></pre>
<p>Using these commands is kinder to the VM than just cycling the power from
the Virtualbox control panel.</p>
<h1>Gritty Details of the Nitty Variety<a id="#nitty-gritty" name="#nitty-gritty"></a></h1>
Image". This will mount the CD's ISO image on the VM.</li>
<li>On the guest VM, it may be necessary to mount the CD image that's now
available:<br>
- <pre># sudo mount /dev/sr0 /media/cdrom</pre>
+ <pre><span style="font-weight: bold;">sudo mount /dev/sr0 /media/cdrom</span></pre>
<p>Linux will mention that the device is mounted "read-only".</p>
</li>
<li>Since the VM currently has no windowing system installed, one must
start the Guest Additions install manually:<br>
- <pre># cd /media/cdrom<br># sudo sh VBoxLinuxAdditions.run</pre>
+ <pre><span style="font-weight: bold;">cd /media/cdrom<br>sudo sh VBoxLinuxAdditions.run</span></pre>
</li>
<li>The latest Virtualbox guest additions should now be installed.</li>
</ol>
<p>To minimize the size used for the disk image, there are three major
steps.</p>
<p>1. While running the VM, run this command:</p>
- <pre># sudo apt clean</pre>
+ <pre><span style="font-weight: bold;">sudo apt clean</span></pre>
<p>This throws away any cached data from the apt tool, which can be
substantial.</p>
<p>If there are other junk files you know of that can be removed, delete
<p>2. Reboot the VM to the gparted ISO image (available at the <a target="_blank"
title="great free partition editor" href="https://gparted.org/livecd.php">gparted
site</a>) and run the following command:</p>
- <pre># sudo zerofree /dev/sda</pre>
+ <pre><span style="font-weight: bold;">sudo zerofree /dev/sda</span></pre>
<p>This sets all free space to the zero byte, enabling Virtualbox to free
that space in the next step.</p>
<p>3. Shut the vm down after zerofree is complete and run this command on
the host PC (this is the Linux version of the command):</p>
- <pre># VBoxManage modifyhd --compact ~/cake_lamp_vm/cake-lamp-vm-hd.vdi</pre>
+ <pre><span style="font-weight: bold;">VBoxManage modifyhd --compact ~/cake_lamp_vm/cake-lamp-vm-hd.vdi</span></pre>
<p>Replace the <span style="font-family: monospace;">~/cake_lamp_vm</span>
path with the real VM storage path. This command compacts the root
(and only) partition of the VM.</p>
