<h1 id="freebsd-jails-on-freenas">FreeBSD Jails on FreeNAS</h1>
|
||
|
|
<p>Mostly a personal distillation for getting a FreeBSD
|
||
|
|
Jail up and running on FreeNAS.</p>
|
||
|
|
<h2 id="in-the-freenas-webgui-create-a-new-jail">In The FreeNAS WebGui, Create A New Jail</h2>
|
||
|
|
<p>The default networking configuration, will give
|
||
|
|
your jail an ip address on the lan. For now, I've
|
||
|
|
decided to just share a pkg cache with each jail.
|
||
|
|
Navigate to <code>Jails -> Storage -> Add Storage</code> and
|
||
|
|
add the <code>pkg</code> storage directory to <code>/var/cache/pkg</code>
|
||
|
|
inside the jail. </p>
|
||
|
|
<p>For instance, on my local FreeNAS server,
|
||
|
|
the pkg directory is at /mnt/VolumeOne/pkg/.</p>
|
||
|
|
<p>If you ssh into the host server, you can type the command
|
||
|
|
<code>jls</code>, to list the jails. Based on the output of the
|
||
|
|
command <code>jls</code>, you can get a shell with <code>jexec <jail number></code>
|
||
|
|
of <code>jexec <jail hostname></code>.</p>
|
||
|
|
<h3 id="updating">updating</h3>
|
||
|
|
<p>How about the command <code>pkg audit -F</code>? Downloads a
|
||
|
|
list of known security issues and checks your system
|
||
|
|
against that.</p>
|
||
|
|
<p>I would recommend, to myself anyway, to shell into
|
||
|
|
the new jail with <code>jexec</code>, run <code>pkg upgrade</code> to install any new packages,
|
||
|
|
and then from the FreeNAS webgui, restart the jail. Although
|
||
|
|
the restarted jail will have a new jail number as reported by
|
||
|
|
the <code>jls</code> command.</p>
|
||
|
|
<h3 id="locale">locale</h3>
|
||
|
|
<p>When you use <code>jexec</code> to get a shell, you get an environment
|
||
|
|
with an utf_8 locale. Not so if you ssh into the new jail.
|
||
|
|
For this put the following contents into ~/.login_conf</p>
|
||
|
|
<pre><code class="conf"># ~/.login_conf
|
||
|
|
me:\
|
||
|
|
:charset=UTF-8:\
|
||
|
|
:lang=en_US.UTF-8:\
|
||
|
|
:setenv=LC_COLLATE=C:
|
||
|
|
</code></pre>
|
||
|
|
|
||
|
|
<h3 id="ssh">ssh</h3>
|
||
|
|
<p>To get ssh running, edit <code>/etc/rc.conf</code> inside the jail.</p>
|
||
|
|
<pre><code class="conf"># /etc/rc.conf
|
||
|
|
sshd_enable="YES"
|
||
|
|
</code></pre>
|
||
|
|
|
||
|
|
<p>To start sshd immediately, make any necessary edits to
|
||
|
|
/etc/ssh/sshd_config, and run the following command.</p>
|
||
|
|
<pre><code class="csh">service sshd start
|
||
|
|
</code></pre>
|
||
|
|
|
||
|
|
<h2 id="byobu">Byobu</h2>
|
||
|
|
<p>You'll need newt to configure byobu, and if you don't install tmux
|
||
|
|
then screen will become the backend.</p>
|
||
|
|
<pre><code class="csh">pkg install byobu tmux newt
|
||
|
|
</code></pre>
|
||
|
|
|
||
|
|
<p>If you execute <code>byobu-config</code>, by pressing <em>f9</em>, the
|
||
|
|
following options seem to work. Some options, of course,
|
||
|
|
will prevent others from working so you have to enable them
|
||
|
|
one at a time to see what happens.</p>
|
||
|
|
<ul>
|
||
|
|
<li>date</li>
|
||
|
|
<li>disk</li>
|
||
|
|
<li>distro</li>

||
|
|

|

<li>users</li>
|
||
|
|
<li>whoami</li>
|
||
|
|
</ul>
|
||
|
|
<h2 id="vim">vim</h2>
|
||
|
|
<p>Via pkg, there are two options: vim and vim-lite. Note vim will pull
|
||
|
|
in a whole bunch of gui dependancies, but vim-lite is not build with python.</p>
|
||
|
|
<p>For instance, powerline will not work with vim-lite because it's not built with
|
||
|
|
python. Also, vim-youcompleteme will not work with vim-lite. However, lightline
|
||
|
|
will work with vim-lite, and VimCompletesMe will work with vim-lite.</p>
|
||
|
|
<p>To get lightline working update $TERM</p>
|
||
|
|
<pre><code class="config"># ~/.config/fish/config.fish
|
||
|
|
export TERM=xterm-256color
|
||
|
|
</code></pre>
|
||
|
|
|
||
|
|
<p>And vimrc</p>
|
||
|
|
<pre><code class="vim"># ~/.vimrc
|
||
|
|
set ls=2
|
||
|
|
</code></pre>
|
||
|
|
|
||
|
|
<p>Another option is to build vim from source via ports. You can prevent vim
|
||
|
|
from pulling in a bunch of gui dependancies with the following in /etc/make.conf.</p>
|
||
|
|
<pre><code class="conf"># /etc/make.conf
|
||
|
|
WITHOUT_X11=yes
|
||
|
|
</code></pre>
|
||
|
|
|
||
|
|
<p>And then when you compile vim from ports, run <code>make config</code> where you can enable
|
||
|
|
python.</p>
|
||
|
|
<h2 id="python">python</h2>
|
||
|
|
<p>For python3 virtualenv</p>
|
||
|
|
<pre><code class="csh">virtualenv-3.6 <directory>
|
||
|
|
</code></pre>
