<p>Before starting, check out <a href="../torwebsite/index.html">this</a> tutorial on how to create your first hidden service.</p>

<p>Then, we make sure that the tor hidden service includes the XMPP ports:</p>
<pre><code class="nim">

</code></pre>
<p>Here, my hidden service is aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.onion, let's check that the mod_onions module is installed and configure the prosody.cfg.lua file:</p>

<p>all good now, now let's connect to it using pidgin:</p>
<pre><code class="nim">
[ mainpc ] [ /dev/pts/9 ] [~/Nextcloud/blog]
→ apt install pidgin -y
[ mainpc ] [ /dev/pts/9 ] [~/Nextcloud/blog]
→ pidgin
</code></pre>
<p>Then, create your account on the XMPP server:</p>

<img src="3.png" class="imgRz">
<img src="4.png" class="imgRz">

<img src="5.png" class="imgRz">
<p>Next, we can start chatting with Alice, who is another user on that XMPP server like so:</p>
<img src="7.png" class="imgRz">
<p>Then from Alice's XMPP client, we accept nihilist's buddy request:</p>

<h2><b>Optional XMPP server options:</b></h2> </br> </br>
<p>if you want to enable message archiving, enable the "mam" module by uncommenting it:</p>
<pre><code class="nim">
root@ANON-home:~# vim /etc/prosody/prosody.cfg.lua
root@ANON-home:~# cat /etc/prosody/prosody.cfg.lua
[...]
modules_enabled = {
"mam"; -- Store recent messages to allow multi-device synchronization
}
[...]
</code></pre>
<p>and then you can mention the expiration time of messages like so:</p>
<pre><code class="nim">
root@ANON-home:~# vim /etc/prosody/prosody.cfg.lua
root@ANON-home:~# cat /etc/prosody/prosody.cfg.lua
archive_expires_after = "1w" -- remove archived messages after 1 week
</code></pre>
<p>you can choose to limit the bandwidth usage of your server too, using the mod_limits module:</p>
<pre><code class="nim">
root@ANON-home:~# vim /etc/prosody/prosody.cfg.lua
root@ANON-home:~# cat /etc/prosody/prosody.cfg.lua
limits = {
c2s = {
rate = "10kb/s";
}
s2sin = {
rate = "30kb/s";
}
}
</code></pre>
<p>You can also enable archiving on the multi-user chats like so :</p>
<pre><code class="nim">
root@ANON-home:~# vim /etc/prosody/prosody.cfg.lua
root@ANON-home:~# cat /etc/prosody/prosody.cfg.lua
Component "conference.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.onion" "muc"
modules_enabled = { "onions", "muc_mam" };
onions_only = true;
</code></pre>
<p>And just like in mod_mam, you can set the expiration time of the messages in MUCs:</p>
<pre><code class="nim">
root@ANON-home:~# vim /etc/prosody/prosody.cfg.lua
root@ANON-home:~# cat /etc/prosody/prosody.cfg.lua
Component "conference.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.onion" "muc"
modules_enabled = { "onions", "muc_mam" };
onions_only = true;
muc_log_expires_after = "1w"
</code></pre>
<p>Then, you can also enable file archiving using mod_http_file_share:</p>
<pre><code class="nim">
root@ANON-home:~# vim /etc/prosody/prosody.cfg.lua
root@ANON-home:~# cat /etc/prosody/prosody.cfg.lua
Component "upload.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.onion" "http_file_share"
modules_enabled = { "onions" };
onions_only = true;
http_file_share_daily_quota = 100*1024*1024; -- 100 MiB
http_file_share_after = 7*86400; -- One week in seconds
http_file_share_size_limit = 10*1024*1024 -- 10 Mib
</code></pre>
<p>Then, as you're going to have a multi user chat, you'll most likely need the mod_muc_moderation module:</p>
<pre><code class="nim">
root@ANON-home:~# vim /etc/prosody/prosody.cfg.lua
root@ANON-home:~# cat /etc/prosody/prosody.cfg.lua
Component "conference.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.onion" "muc"
modules_enabled = { "onions", "muc_mam", "muc_moderation" };
onions_only = true;
muc_log_expires_after = "1w"
