<h2>The Zephyr mirror script (not recommended)</h2>
|
||
|
|
|
||
|
|
<p>Webathena is the easiest way to use Zulip. With Webathena, you don't need
|
||
|
|
to run any software in a screen session. Your Athena password never leaves
|
||
|
|
your computer and the only access that any Zulip computer ever receives is the
|
||
|
|
ability to send/receive zephyrs as you.</p>
|
||
|
|
|
||
|
|
<p>We recommend that you use Webathena instead of following these instructions.
|
||
|
|
Please only follow these instructions if you know that you want to run the zephyr
|
||
|
|
mirror script instead of using Webathena.</p>
|
||
|
|
|
||
|
|
<h3 id="mirror">Running the Zephyr mirror script</h3>
|
||
|
|
<p>On an Athena dialup
|
||
|
|
(<a href="https://linerva.mit.edu">linerva.mit.edu</a>,
|
||
|
|
<a href="https://athena.dialup.mit.edu">athena.dialup.mit.edu</a>,
|
||
|
|
etc.), run the Zephyr mirroring script inside a screen
|
||
|
|
session.</p>
|
||
|
|
|
||
|
|
<p><strong>IMPORTANT: You must keep the Zephyr mirroring script
|
||
|
|
always running in a session with unexpired Kerberos
|
||
|
|
tickets.</strong> The script forwards personals you receive on
|
||
|
|
Zephyr to Zulip, and forwards messages you send in Zulip to
|
||
|
|
Zephyr. <strong>If it is not running, only other Zulip users
|
||
|
|
will receive messages you send from Zulip!</strong>. The Zulip
|
||
|
|
web application will warn you if the Zephyr mirroring script is
|
||
|
|
not running.</p>
|
||
|
|
|
||
|
|
<p>If you already have Barnowl running in screen/tmux somewhere,
|
||
|
|
you can just run:</p>
|
||
|
|
|
||
|
|
<p><code>/mit/tabbott/humbug/zephyr_mirror.py</code></p>
|
||
|
|
|
||
|
|
<p>inside that screen session.</p>
|
||
|
|
|
||
|
|
<h4>Mirroring without a Barnowl session</h4>
|
||
|
|
|
||
|
|
<p>If you are not already running a screen/tmux for Barnowl, you
|
||
|
|
can setup a screen session to run the Zephyr mirroring script by
|
||
|
|
running the following on a dialup such
|
||
|
|
as <a href="https://linerva.mit.edu">linerva.mit.edu</a>:</p>
|
||
|
|
|
||
|
|
<ol>
|
||
|
|
<li><code>kinit -l7d && aklog</code></li>
|
||
|
|
<li>(Type your password to create 7-day renewable Kerberos tickets)</li>
|
||
|
|
<li><code>env ZEPHYR_SCREEN_CLIENT=/mit/tabbott/humbug/zephyr_mirror.py
|
||
|
|
SCREEN_SESSION_NAME=humbug athrun kchen owl-screen
|
||
|
|
</code></li>
|
||
|
|
</ol>
|
||
|
|
|
||
|
|
<p>This will run the Zephyr Mirroring script inside a screen
|
||
|
|
session, and use `/mit/kchen/bin/cont-renew-notify` to continually
|
||
|
|
renew your Kerberos tickets for up to a week; each week, it will
|
||
|
|
send you a Zephyr/Zulip letting you know that you need to renew
|
||
|
|
your tickets. To do so, login to the server that you setup the
|
||
|
|
screen session on and use the following procedure:</p>
|
||
|
|
|
||
|
|
<ol>
|
||
|
|
<li>Run <code>screen -x humbug</code> to connect to the mirroring
|
||
|
|
screen session created above.</li>
|
||
|
|
<li>The first time, you'll need to type <code>ctrl-a c</code> to switch to a new terminal in your screen session.</li>
|
||
|
|
<li><code>kinit -l7d && aklog</code></li>
|
||
|
|
<li>(Type type your password to renew your Kerberos tickets).</li>
|
||
|
|
</ol>
|
||
|
|
|
||
|
|
<p>Don't run multiple copies of the Zephyr mirroring script;
|
||
|
|
doing so will result in messages you sent being forwarded to
|
||
|
|
Zephyr twice.</p>
