    <h2>Zephyr Mirroring for Zulip</h2>

<p>Thanks for giving Zulip a try!  This page describes how to use
  Zulip with MIT Zephyr; if you're not a current Zephyr user,
  you probably want to visit the main Zulip website.</p>

<p>There are a few steps you need to take to setup Zulip for your
MIT Zephyr account.</p>

<h3>First time setup</h3>
<ol>
  <li><p>Create a password and activate your account using the URL in
  your email.</p></li>

  <li><p>Get your API key from the "Settings" panel and put it in a file in your
    Athena home directory called <code>~/Private/.humbug-api-key</code>.</p></li>

  <li><p>Copy over your Zephyr subscriptions</p>

    <p>If you would like to copy over all of your subscriptions, please
    run the following command:<br />
            <code>/mit/tabbott/humbug/zephyr_mirror.py --sync-subscriptions</code></p>

    <p> NOTE: Zulip does not fully support the equivalent of Barnowl
    filters.  If you have too many subscriptions (you know who you
    are), you may want to either manually subscribe to just your main
    barnowl view or make extensive use of the "Not in home view"
    option on streams. You can add or remove subscriptions from the
    Zulip app (or your Zulip home view) by clicking the gear in the
    upper right-hand corner and then selecting "Streams."</p>
</ol>

<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>
