Y esto está perro porque si tú tienes tu propio server, así como con uno de correo electrónico, puedes controlar qué características tiene, quiénes pueden hacer cuenta, si hay <em>end-to-end encryption</em> (o mínimo <em>end-to-server</em>), entre un montón de otras cosas.</p> +<p>Ahorita este server es SUMISO (<em>compliant</em> en español, jeje) para jalar con la app <a href="https://conversations.im/">conversations</a> y con la red social <a href="https://movim.eu/">movim</a>, pero realmente funcionaría con casi cualquier cliente de XMPP, amenos que ese cliente implemente algo que no tiene mi server. Y también acomodé un server de <a href="https://matrix.org/">Matrix</a> que es muy similar pero es bajo otro protocolo y se siente más como un discord/slack (al menos en el <a href="https://element.io/">element</a>), muy chingón también.</p> +<p>Si bien aún quedan cosas por hacer sobre estos dos servers que me acomodé (además de hacerles unas entradas para documentar cómo lo hice), quiero moverme a otra cosa que sería acomodar una sección de dibujos, lo cual en teoría es bien sencillo, pero como quiero poder automatizar la publicación de estos, quiero modificar un poco el <a href="https://github.com/luevano/pyssg">pyssg</a> para que jale chido para este pex.</p> +<p>Ya por último también quiero moverle un poco al CSS, porque lo dejé en un estado muy culerón y quiero meterle/ajustar unas cosas para que quede más limpio y medianamente bonito… <em>dentro de lo que cabe porque evidentemente me vale verga si se ve como una página del 2000</em>.</p> + + <div class="page-nav"> + <span class="next"> + <a href="https://blog.luevano.xyz/a/acomodada_la_pagina_de_arte.html" alt="Next"> + <i class="fas fa-arrow-left" alt="Arrow left"></i> + <span>Next</span> + </a> + </span> + + <span class="index"> + <a href="https://blog.luevano.xyz" alt="Index"> + <i class="fas fa-home" alt="Home"></i> + <span>Index</span> + </a> + </span> + + <span class="previous"> + <a href="https://blog.luevano.xyz/a/new_blogging_system.html" alt="Previous"> + <i class="fas fa-arrow-right" alt="Arrow right"></i> + <span>Previous</span> + </a> + </span> +</div> + + + <hr> + <div class="article-info"> + <p>By David Luévano</p> + <p>Created: Fri, Jun 04, 2021 @ 08:24 UTC</p> + <div class="article-tags"> + <p>Tags: +<a href="https://blog.luevano.xyz/tag/@short.html">short</a>, <a href="https://blog.luevano.xyz/tag/@spanish.html">spanish</a>, <a href="https://blog.luevano.xyz/tag/@update.html">update</a> </p> +</div> + + </div> + </main> + + <footer> +<span> + <i class="fas fa-address-card" alt="Contact"></i> + <a href="https://blog.luevano.xyz/contact.html">Contact</a> +</span> + +<span> + <i class="fas fa-donate" alt="Donate"></i> + <a href="https://blog.luevano.xyz/donate.html">Donate</a> +</span> + +<span> + <i class="fas fa-rss" alt="RSS"></i> + <a target="_blank" href="https://blog.luevano.xyz/rss.xml">RSS</a> +</span> + +<br> +<span class="created-with"> + <i class="fas fa-hammer" alt="Hammer"></i> + Created with <a href="https://github.com/luevano/pyssg">pyssg</a> +</span> + +<br> +<span class="copyright"> + Copyright <i class="far fa-copyright" alt="Copyright"></i> 2023 David Luévano Alvarado +</span> + + </footer> + </body> +</html>

Pero bueno, antes que nada este pex ocupa un poco de contexto sobre dos cositas:</p> +<ul> +<li><a href="https://tachiyomi.org/">Tachiyomi</a>: Una aplicación de android que uso para descargar y leer manga. Lo importante aquí es que por default se guardan los mangas con cada página siendo una sola imagen, por lo que al mover el manga de un lado a otro tarda mucho tiempo.</li> +<li><a href="https://source.android.com/devices/storage/adoptable">Adoptable storage</a>: Un <em>feature</em> de android que básicamente te deja usar una micro SD (mSD) externa como si fuera interna, encriptando y dejando la mSD inutilizable en cualquier otro dispositivo. La memoria interna se <em>pierde</em> o algo por el estilo (bajo mi experiencia), por lo que parece es bastante útil cuando la capacidad de la memoria interna es baja.</li> +</ul> +<p>Ahora sí vamonos por partes, primero que nada lo que sucedió fue que ordené una mSD con más capacidad que la que ya tenía (64 GB -> 512 GB, poggies), porque últimamente he estado bajando y leyendo mucho manga entonces me estaba quedando sin espacio. Ésta llegó el día de mi cumpleaños lo cuál estuvo chingón, me puse a hacer backup de la mSD que ya tenía y preparando todo, muy bonito, muy bonito.</p> +<p>Empecé a tener problemas, porque al estar moviendo tanto archivo pequeño (porque recordemos que el <em>tachiyomi</em> trata a cada página como una sola imagen), la conexión entre el celular y mi computadora se estaba corte y corte por alguna razón; en general muchos pedos. Por lo que mejor le saqué la nueva mSD y la metí directo a mi computadora por medio de un adaptador para batallar menos y que fuera más rápido.</p> +<p>Hacer este pedo de mover archivos directamente en la mSD puede llevar a corromper la memoria, no se los detalles pero pasa (o quizá estoy meco e hice algo mal). Por lo que al terminar de mover todo a la nueva mSD y ponerla en el celular, éste se emputó que porque no la detectaba y que quería tirar un formateo a la mSD. A este punto no me importaba mucho, sólo era questión de volvera mover archivos y ser más cuidadoso; “<em>no issues from my end</em>” diría en mis <em>standups</em>.</p> +<p>Todo valió <strong>vergota</strong> porque en cierto punto al elegir sí formatear la mSD mi celular me daba la opción de “<em>usar la micro SD para el celular</em>” o “<em>usar la micro SD como memoria portátil</em>” (o algo entre esas líneas), y yo, estúpidamente, elegí la primera, porque me daba sentido: “no, pues simón, voy a usar esta memoria para este celular”.</p> +<p>Pues mamé, resulta que esa primera opción lo que realmente quería decir es que se iba a usar la micro SD como interna usando el pex este de <em>adoptable storage</em>. Entonces básicamente <em>perdí</em> mi capacidad de memoria interna (128 GB aprox.), y toda la mSD nueva se usó como memoria interna. Todo se juntó, si intentaba sacar la mSD todo se iba a la mierda y no podía usar muchas aplicaciones. “<em>No hay pedo</em>”, pensé, “<em>nada más es cuestión de desactivar esta mamada de adoptable storage</em>”.</p> +<p>Ni madres dijeron los devs de Android, este pedo nada más es un <em>one-way</em>: puedes activar <em>adoptable storage</em> pero para desactivarlo <strong>ocupas, a huevo, formatear tu celular a estado de fábrica</strong>. Chingué a mi madre, comí mierda, perdí.</p> +<p>Pues eso fue lo que hice, ni modo. Hice backup de todo lo que se me ocurrió (también me di cuenta que G**gl* authenticator es cagada ya que no te deja hacer backup, entre otras cosas, mejor usen <a href="https://getaegis.app/">Aegis authenticator</a>), desactivé todo lo que se tenía que desactivar y tocó hacer <em>factory reset</em>, ni modo. Pero como siempre las cosas salen mal y tocó comer mierda del banco porque me bloquearon la tarjeta, perdí credenciales necesarias para el trabajo (se resolvió rápido), etc., etc.. Ya no importa, ya casi todo está resuelto, sólo queda ir al banco a resolver lo de la tarjeta bloqueada (esto es para otro <em>rant</em>, pinches apps de bancos piteras, ocupan hacer una sola cosa y la hacen mal).</p> +<p>Al final del día, la causa del problema fueron los malditos mangas (por andar queriendo <em>backupearlos</em>), que terminé bajando de nuevo manualmente y resultó mejor porque aparentemente <em>tachiyomi</em> agregó la opción de “<em>zippear</em>” los mangas en formato <a href="https://docs.fileformat.com/ebook/cbz/">CBZ</a>, por lo que ya son más fácil de mover de un lado para otro, el fono no se queda pendejo, etc., etc..</p> +<p>Por último, quiero decir que los devs de Android son unos pendejos por no hacer reversible la opción de <em>adoptable storage</em>, y los de MIUI son todavía más por no dar detalles de lo que significan sus opciones de formateo, especialmente si una opción es tan chingadora que para revertirla necesitas formatear a estado de fábrica tu celular; más que nada es culpa de los de MIUI, todavía que ponen un chingo de A(i)DS en todas sus apps, no pueden poner una buena descripción en sus opciones. <strong>REEEE</strong>.</p> + + <div class="page-nav"> + <span class="next"> + <a href="https://blog.luevano.xyz/a/password_manager_authenticator_setup.html" alt="Next"> + <i class="fas fa-arrow-left" alt="Arrow left"></i> + <span>Next</span> + </a> + </span> + + <span class="index"> + <a href="https://blog.luevano.xyz" alt="Index"> + <i class="fas fa-home" alt="Home"></i> + <span>Index</span> + </a> + </span> + + <span class="previous"> + <a href="https://blog.luevano.xyz/a/volviendo_a_usar_la_pagina.html" alt="Previous"> + <i class="fas fa-arrow-right" alt="Arrow right"></i> + <span>Previous</span> + </a> + </span> +</div> + + + <hr> + <div class="article-info"> + <p>By David Luévano</p> + <p>Created: Sun, May 15, 2022 @ 09:51 UTC</p> + <p>Modified: Sun, May 15, 2022 @ 10:03 UTC</p> + <div class="article-tags"> + <p>Tags: +<a href="https://blog.luevano.xyz/tag/@rant.html">rant</a>, <a href="https://blog.luevano.xyz/tag/@spanish.html">spanish</a>, <a href="https://blog.luevano.xyz/tag/@update.html">update</a> </p> +</div> + + </div> + </main> + + <footer> +<span> + <i class="fas fa-address-card" alt="Contact"></i> + <a href="https://blog.luevano.xyz/contact.html">Contact</a> +</span> + +<span> + <i class="fas fa-donate" alt="Donate"></i> + <a href="https://blog.luevano.xyz/donate.html">Donate</a> +</span> + +<span> + <i class="fas fa-rss" alt="RSS"></i> + <a target="_blank" href="https://blog.luevano.xyz/rss.xml">RSS</a> +</span> + +<br> +<span class="created-with"> + <i class="fas fa-hammer" alt="Hammer"></i> + Created with <a href="https://github.com/luevano/pyssg">pyssg</a> +</span> + +<br> +<span class="copyright"> + Copyright <i class="far fa-copyright" alt="Copyright"></i> 2023 David Luévano Alvarado +</span> + + </footer> + </body> +</html>

I’m basically following <a href="https://git-scm.com/book/en/v2/Git-on-the-Server-Setting-Up-the-Server">git’s guide on setting up a server</a> plus some specific stuff for (btw i use) Arch Linux (<a href="https://wiki.archlinux.org/index.php/Git_server#Web_interfaces">Arch Linux Wiki: Git server</a> and <a href="https://miracoin.wordpress.com/2014/11/25/step-by-step-guide-on-setting-up-git-server-in-arch-linux-pushable/">Step by step guide on setting up git server in arch linux (pushable)</a>).</p> +<p>Note that this is mostly for personal use, so there’s no user/authentication control other than that of SSH. Also, most if not all commands here are run as root.</p> +<h2 id="prerequisites">Prerequisites</h2> +<p>I might get tired of saying this (it’s just copy paste, basically)… but you will need the same prerequisites as before (check my <a href="https://blog.luevano.xyz/a/website_with_nginx.html">website</a> and <a href="https://blog.luevano.xyz/a/mail_server_with_postfix.html">mail</a> entries), with the extras:</p> +<ul> +<li>(Optional, if you want a “front-end”) A <strong>CNAME</strong> for “git” and (optionally) “www.git”, or some other name for your sub-domains.</li> +<li>An SSL certificate, if you’re following the other entries, add a <code>git.conf</code> and run <code>certbot --nginx</code> to extend the certificate.</li> +</ul> +<h2 id="git">Git</h2> +<p><a href="https://wiki.archlinux.org/title/git">Git</a> is a version control system.</p> +<p>If not installed already, install the <code>git</code> package:</p> +<pre><code class="language-sh">pacman -S git +</code></pre> +<p>On Arch Linux, when you install the <code>git</code> package, a <code>git</code> user is automatically created, so all you have to do is decide where you want to store the repositories, for me, I like them to be on <code>/home/git</code> like if <code>git</code> was a “normal” user. So, create the <code>git</code> folder (with corresponding permissions) under <code>/home</code> and set the <code>git</code> user’s home to <code>/home/git</code>:</p> +<pre><code class="language-sh">mkdir /home/git +chown git:git /home/git +usermod -d /home/git git +</code></pre> +<p>Also, the <code>git</code> user is “expired” by default and will be locked (needs a password), change that with:</p> +<pre><code class="language-sh">chage -E -1 git +passwd git +</code></pre> +<p>Give it a strong one and remember to use <code>PasswordAuthentication no</code> for <code>ssh</code> (as you should). Create the <code>.ssh/authorized_keys</code> for the <code>git</code> user and set the permissions accordingly:</p> +<pre><code class="language-sh">mkdir /home/git/.ssh +chmod 700 /home/git/.ssh +touch /home/git/.ssh/authorized_keys +chmod 600 /home/git/.ssh/authorized_keys +chown -R git:git /home/git +</code></pre> +<p>Now is a good idea to copy over your local SSH public keys to this file, to be able to push/pull to the repositories. Do it by either manually copying it or using <code>ssh</code>‘s built in <code>ssh-copy-id</code> (for that you may want to check your <code>ssh</code> configuration in case you don’t let people access your server with user/password).</p> +<p>Next, and almost finally, we need to edit the <code>git-daemon</code> service, located at <code>/usr/lib/systemd/system/</code> (called <code>git-daemon@.service</code>):</p> +<pre><code class="language-ini">... +ExecStart=-/usr/lib/git-core/git-daemon --inetd --export-all --base-path=/home/git --enable=receive-pack +... +</code></pre> +<p>I just appended <code>--enable=receive-pack</code> and note that I also changed the <code>--base-path</code> to reflect where I want to serve my repositories from (has to match what you set when changing <code>git</code> user’s home).</p> +<p>Now, go ahead and start and enable the <code>git-daemon</code> socket:</p> +<pre><code class="language-sh">systemctl start git-daemon.socket +systemctl enable git-daemon.socket +</code></pre> +<p>You’re basically done. Now you should be able to push/pull repositories to your server… except, you haven’t created any repository in your server, that’s right, they’re not created automatically when trying to push. To do so, you have to run (while inside <code>/home/git</code>):</p> +<pre><code class="language-sh">git init --bare {repo_name}.git +chown -R git:git repo_name.git +</code></pre> +<p>Those two lines above will need to be run each time you want to add a new repository to your server (yeah, kinda lame… although there are options to “automate” this, I like it this way).</p> +<p>After that you can already push/pull to your repository. I have my repositories (locally) set up so I can push to more than one remote at the same time (my server, GitHub, GitLab, etc.); to do so, check <a href="https://gist.github.com/rvl/c3f156e117e22a25f242">this gist</a>.</p> +<h2 id="cgit">Cgit</h2> +<p><a href="https://wiki.archlinux.org/title/Cgit">Cgit</a> is a fast web interface for git.</p> +<p>This is optionally since it’s only for the web application.</p> +<p>Install the <code>cgit</code> and <code>fcgiwrap</code> packages:</p> +<pre><code class="language-sh">pacman -S cgit fcgiwrap +</code></pre> +<p>Now, just start and enable the <code>fcgiwrap</code> socket:</p> +<pre><code class="language-sh">systemctl start fcgiwrap.socket +systemctl enable fcgiwrap.socket +</code></pre> +<p>Next, create the <code>git.conf</code> as stated in my <a href="https://blog.luevano.xyz/a/website_with_nginx.html">nginx setup entry</a>. Add the following lines to your <code>git.conf</code> file:</p> +<pre><code class="language-nginx">server { + listen 80; + listen [::]:80; + root /usr/share/webapps/cgit; + server_name {yoursubdomain}.{yourdomain}; + try_files $uri @cgit; + + location @cgit { + include fastcgi_params; + fastcgi_param SCRIPT_FILENAME $document_root/cgit.cgi; + fastcgi_param PATH_INFO $uri; + fastcgi_param QUERY_STRING $args; + fastcgi_param HTTP_HOST $server_name; + fastcgi_pass unix:/run/fcgiwrap.sock; + } +} +</code></pre> +<p>Where the <code>server_name</code> line depends on you, I have mine setup to <code>git.luevano.xyz</code> and <code>www.git.luevano.xyz</code>. Optionally run <code>certbot --nginx</code> to get a certificate for those domains if you don’t have already.</p> +<p>Now, all that’s left is to configure <code>cgit</code>. Create the configuration file <code>/etc/cgitrc</code> with the following content (my personal options, pretty much the default):</p> +<pre><code class="language-apache">css=/cgit.css +logo=/cgit.png + +enable-http-clone=1 +# robots=noindex, nofollow +virtual-root=/ + +repo.url={url} +repo.path={dir_path} +repo.owner={owner} +repo.desc={short_description} + +... +</code></pre> +<p>Where you can uncomment the <code>robots</code> line to let web crawlers (like Google’s) to index your <code>git</code> web app. And at the end keep all your repositories (the ones you want to make public), for example for my <a href="https://git.luevano.xyz/.dots"><em>dotfiles</em></a> I have:</p> +<pre><code class="language-apache">... +repo.url=.dots +repo.path=/home/git/.dots.git +repo.owner=luevano +repo.desc=These are my personal dotfiles. +... +</code></pre> +<p>Otherwise you could let <code>cgit</code> to automatically detect your repositories (you have to be careful if you want to keep “private” repos) using the option <code>scan-path</code> and setup <code>.git/description</code> for each repository. For more, you can check <a href="https://man.archlinux.org/man/cgitrc.5">cgitrc(5)</a>.</p> +<p>By default you can’t see the files on the site, you need a highlighter to render the files, I use <code>highlight</code>. Install the <code>highlight</code> package:</p> +<pre><code class="language-sh">pacman -S highlight +</code></pre> +<p>Copy the <code>syntax-highlighting.sh</code> script to the corresponding location (basically adding <code>-edited</code> to the file):</p> +<pre><code class="language-sh">cp /usr/lib/cgit/filters/syntax-highlighting.sh /usr/lib/cgit/filters/syntax-highlighting-edited.sh +</code></pre> +<p>And edit it to use the version 3 and add <code>--inline-css</code> for more options without editing <code>cgit</code>‘s CSS file:</p> +<pre><code class="language-sh">... +# This is for version 2 +# exec highlight --force -f -I -X -S "$EXTENSION" 2>/dev/null + +# This is for version 3 +exec highlight --force --inline-css -f -I -O xhtml -S "$EXTENSION" 2>/dev/null +... +</code></pre> +<p>Finally, enable the filter in <code>/etc/cgitrc</code> configuration:</p> +<pre><code class="language-apache">source-filter=/usr/lib/cgit/filters/syntax-highlighting-edited.sh +</code></pre> +<p>That would be everything. If you need support for more stuff like compressed snapshots or support for markdown, check the optional dependencies for <code>cgit</code>.</p> + + <div class="page-nav"> + <span class="next"> + <a href="https://blog.luevano.xyz/a/new_blogging_system.html" alt="Next"> + <i class="fas fa-arrow-left" alt="Arrow left"></i> + <span>Next</span> + </a> + </span> + + <span class="index"> + <a href="https://blog.luevano.xyz" alt="Index"> + <i class="fas fa-home" alt="Home"></i> + <span>Index</span> + </a> + </span> + + <span class="previous"> + <a href="https://blog.luevano.xyz/a/mail_server_with_postfix.html" alt="Previous"> + <i class="fas fa-arrow-right" alt="Arrow right"></i> + <span>Previous</span> + </a> + </span> +</div> + + + <hr> + <div class="article-info"> + <p>By David Luévano</p> + <p>Created: Sun, Mar 21, 2021 @ 19:00 UTC</p> + <p>Modified: Tue, Jun 08, 2021 @ 07:27 UTC</p> + <div class="article-tags"> + <p>Tags: +<a href="https://blog.luevano.xyz/tag/@english.html">english</a>, <a href="https://blog.luevano.xyz/tag/@server.html">server</a>, <a href="https://blog.luevano.xyz/tag/@tools.html">tools</a>, <a href="https://blog.luevano.xyz/tag/@tutorial.html">tutorial</a> </p> +</div> + + </div> + </main> + + <footer> +<span> + <i class="fas fa-address-card" alt="Contact"></i> + <a href="https://blog.luevano.xyz/contact.html">Contact</a> +</span> + +<span> + <i class="fas fa-donate" alt="Donate"></i> + <a href="https://blog.luevano.xyz/donate.html">Donate</a> +</span> + +<span> + <i class="fas fa-rss" alt="RSS"></i> + <a target="_blank" href="https://blog.luevano.xyz/rss.xml">RSS</a> +</span> + +<br> +<span class="created-with"> + <i class="fas fa-hammer" alt="Hammer"></i> + Created with <a href="https://github.com/luevano/pyssg">pyssg</a> +</span> + +<br> +<span class="copyright"> + Copyright <i class="far fa-copyright" alt="Copyright"></i> 2023 David Luévano Alvarado +</span> + + </footer> + </body> +</html>

Muy sencillas tareas.</p> +<p>Primero que nada me levanté de una pesadilla horrible en la que se puede decir que se me subió el muerto al querer despertar, esperé a que fuera casi la hora de salida de mi horario de trabajo, me bañé y fui directo al banco primero. Todo bien hasta aquí.</p> +<p>En el camino al banco, durante la plática con el conductor del Uber salió el tema del horario del banco. Yo muy tranquilo dije “pues voy algo tarde, pero sí alcanzo, cierran a las 5, ¿no?” a lo que me respondió el conductor “nel jefe, a las 4, y se van media hora antes”; quedé. Chequé y efectivamente cerraban a las 4. Entonces le dije que le iba a cambiar la ruta directo a donde me iba a vacunar, pero ya era muy tarde y quedaba para la dirección opuesta.”Ni pedo, ahí déjame y pido otro viaje, no te apures”, le dije y como siempre pues me deseó que se compusiera mi día; <strong>afortunadamente</strong> el banco sí estaba abierto para lo que tenía que hacer, así que fue un buen giro. Me puse muy feliz y asumí que sería un buen día, como me lo dijo mi conductor; <strong>literalmente NO SABÍA</strong>.</p> +<p>Salí feliz de poder haber completado esa misión y poder irme a vacunar. Pedí otro Uber a donde tenía que ir y todo bien. Me tocó caminar mucho porque la entrada estaba en punta de la chingada de donde me dejó el conductor, pero no había rollo, era lo de menos. Me desanimé cuando vi que había una cantidad estúpida de gente, era una fila que abarcaba todo el estacionamiento y daba demasiadas vueltas; “ni pedo”, dije, “si mucho me estaré aquí una hora, hora y media”… otra vez, <strong>literalmente NO SABÍA</strong>.</p> +<p>Pasó media hora y había avanzado lo que parecía ser un cuarto de la fila, entonces todo iba bien. Pues nel, había avanzado el equivalente a un octavo de la fila, este pedo no iba a salir en una hora-hora y media. Para acabarla de chingar era todo bajo el tan amado sol de Chiwawa. “No hay pedo, me entretengo tirando chal con alguien en el wasap”, pues no, aparentemente no cargué el celular y ya tenía 15-20% de batería… volví a quedar.</p> +<p>Se me acabó la pila, ya había pasado una hora y parecía que la fila era infinita, simplemente avanzábamos demasiado lento, a pesar de que los que venían atrás de mí repetían una y otra vez “mira, avanza bien rápido, ya mero llegamos”, ilusos. Duré aproximadamente 3 horas formado, aguantando conversaciones estúpidas a mi alrededor, gente quejándose por estar parada (yo también me estaba quejando pero dentro de mi cabeza), y por alguna razón iban familias completas de las cuales al final del día sólo uno o dos integrantes de la familia entraban a vacunarse.</p> +<p>En fin que se acabó la tortura y ya tocaba irse al cantón, todo bien. “No hay pedo, no me tocó irme en Uber, aquí agarro un camíon” pensé. Pero no, ningún camión pasó durante la hora que estuve esperando y de los 5 taxis que intenté parar <strong>NINGUNO</strong> se detuvo. Decidí irme caminado, ya qué más daba, en ese punto ya nada más era hacer corajes <em>dioquis</em>.</p> +<p>En el camino vi un Oxxo y decidí desviarme para comprar algo de tomar porque andaba bien deshidratado. En el mismo segundo que volteé para ir hacia el Oxxo pasó un camión volando y lo único que pensaba era que el conductor me decía “Jeje ni pedo:)”. Exploté, me acabé, simplemente perdí, saqué el <em>bad ending</em>.</p> +<p>Ya estaba harto y hasta iba a comprar un cargador para ya irme rápido, estaba cansado del día, simplemente ahí terminó la quest, había sacado el peor final. Lo bueno es que se me ocurrió pedirle al cajero un cargador y que me <em>tirara paro</em>. Todo bien, pedí mi Uber y llegué a mi casa sano y a salvo, pero con la peor rabia que me había dado en mucho tiempo. Simplemente ¿mi culo? explotado. Este día me tocó un desarrollo de personaje muy cabrón, se mamó el D*****o.</p> +<p>Lo único rescatable fue que había una (más bien como 5) chica muy guapa en la fila, lástima que los <em>stats</em> de mi personaje me tienen bloqueadas las conversaciones con desconocidos.</p> +<p>Y pues ya, este pex ya me sirvió para desahogarme, una disculpa por la redacción tan <em>pitera</em>.

Write a new program “from scratch” in <em>pYtHoN</em>. Yes it is bloated, yes it is in its early stages, but it works just as I want it to work, and I’m pretty happy so far with the results and have with even more ideas in mind to “optimize” and generally clean my wOrKfLoW to post new blog entries. I even thought of using it for posting into a “feed” like gallery for drawings or pictures in general.</p> +<p>I called it <a href="https://github.com/luevano/pyssg"><code>pyssg</code></a>, because it sounds nice and it wasn’t taken in the PyPi. It is just a terminal program that reads either a configuration file or the options passed as flags when calling the program.</p> +<p>It still uses Markdown files because I find them very easy to work with. And instead of just having a “header” and a “footer” applied to each parsed entry, you will have templates (generated with the program) for each piece that I thought made sense (idea taken from <code>blogit</code>): the common header and footer, the common header and footer for each entry and, header, footer and list elements for articles and tags. When parsing the Markdown file these templates are applied and stitched together to make a single HTML file. Also generates an RSS feed and the <code>sitemap.xml</code> file, which is nice.</p> +<p>It might sound convoluted, but it works pretty well, with of course room to improve; I’m open to suggestions, issue reporting or direct contributions <a href="https://github.com/luevano/pyssg">here</a>. BTW, it only works on Linux for now (and don’t think on making it work on windows, but feel free to do PR for the compatibility).</p> +<p>That’s it for now, the new RSS feed is available here: <a href="https://blog.luevano.xyz/rss.xml">https://blog.luevano.xyz/rss.xml</a>.</p> + + <div class="page-nav"> + <span class="next"> + <a href="https://blog.luevano.xyz/a/asi_nomas_esta_quedando.html" alt="Next"> + <i class="fas fa-arrow-left" alt="Arrow left"></i> + <span>Next</span> + </a> + </span> + + <span class="index"> + <a href="https://blog.luevano.xyz" alt="Index"> + <i class="fas fa-home" alt="Home"></i> + <span>Index</span> + </a> + </span> + + <span class="previous"> + <a href="https://blog.luevano.xyz/a/git_server_with_cgit.html" alt="Previous"> + <i class="fas fa-arrow-right" alt="Arrow right"></i> + <span>Previous</span> + </a> + </span> +</div> + + + <hr> + <div class="article-info"> + <p>By David Luévano</p> + <p>Created: Fri, May 28, 2021 @ 03:21 UTC</p> + <p>Modified: Fri, May 28, 2021 @ 03:42 UTC</p> + <div class="article-tags"> + <p>Tags: +<a href="https://blog.luevano.xyz/tag/@english.html">english</a>, <a href="https://blog.luevano.xyz/tag/@short.html">short</a>, <a href="https://blog.luevano.xyz/tag/@tools.html">tools</a>, <a href="https://blog.luevano.xyz/tag/@update.html">update</a> </p> +</div> + + </div> + </main> + + <footer> +<span> + <i class="fas fa-address-card" alt="Contact"></i> + <a href="https://blog.luevano.xyz/contact.html">Contact</a> +</span> + +<span> + <i class="fas fa-donate" alt="Donate"></i> + <a href="https://blog.luevano.xyz/donate.html">Donate</a> +</span> + +<span> + <i class="fas fa-rss" alt="RSS"></i> + <a target="_blank" href="https://blog.luevano.xyz/rss.xml">RSS</a> +</span> + +<br> +<span class="created-with"> + <i class="fas fa-hammer" alt="Hammer"></i> + Created with <a href="https://github.com/luevano/pyssg">pyssg</a> +</span> + +<br> +<span class="copyright"> + Copyright <i class="far fa-copyright" alt="Copyright"></i> 2023 David Luévano Alvarado +</span> + + </footer> + </body> +</html>

Note that you will still need a <em>master password</em> to lock/unlock your password database (you can additionally use a hardware key and a key file).</p> +<p>Anyways, setting up <em>keepass</em> is pretty simple, as there is a client for almost any device; note that <em>keepass</em> is basically just the format and the base for all of the clients, as its common with pretty much any open source software. In my case I’m using <a href="https://keepassxc.org/">KeePassXC</a> in my computer and <a href="https://www.keepassdx.com/">KeePassDX</a> in my phone (Android). The only concern is keeping everything in sync because <em>keepass</em> doesn’t have any automatic method of synchronizing between devices because of security reasons (as far as I know), meaning that you have to manage that yourself.</p> +<p>Usually you can use something like G**gl* drive, dropbox, mega, nextcloud, or any other cloud solution that you like to sync your <em>keepass</em> database between devices; I personally prefer to use <a href="https://syncthing.net/">Syncthing</a> as it’s open source, it’s really easy to setup and has worked wonders for me since I started using it, also it keeps versions of your files that can serve as backups in any scenario where the database gets corrupted or something.</p> +<p>Finally, when I went through the issue with the micro SD and the <em>adoptable storage</em> bullshit (you can find the rant <a href="https://blog.luevano.xyz/a/devs_android_me_trozaron.html">here</a>, in spanish) I had to also migrate from <em>G**gl* authenticator</em> (<em>gauth</em>) to something else for the simple reason that <em>gauth</em> doesn’t even let you do backups, nor it’s synched with your account… nothing, it is just standalone and if you ever lose your phone you’re fucked; so I decided to go with <a href="https://getaegis.app/">Aegis authenticator</a>, as it is open source, you have control over all your secret keys, you can do backups directly to the filesystem, you can secure your database with an extra password, etc., etc.. In general <em>aegis</em> is the superior MFA authenticator (at least compared with <em>gauth</em>) and everything that’s compatible with <em>gauth</em> is compatible with <em>aegis</em> as the format is a standard (as a matter of fact, <em>keepass</em> also has this MFA feature which is called TOPT and is also compatible, but I prefer to have things separate). I also use <em>syncthing</em> to keep a backup of my <em>aegis</em> database.</p> +<p><strong>TL;DR</strong>:</p> +<ul> +<li><a href="https://syncthing.net/">Syncthing</a> to sync files between devices (for the password databases).</li> +<li><a href="https://keepassxc.org/">KeePassXC</a> for the password manager in my computer.</li> +<li><a href="https://www.keepassdx.com/">KeePassDX</a> for the password manager in my phone.</li> +<li><a href="https://getaegis.app/">Aegis authenticator</a> for the universal MFA authenticator.</li> +</ul> + + <div class="page-nav"> + <span class="next"> + <a href="https://blog.luevano.xyz/g/starting_gamedev_blogging.html" alt="Next"> + <i class="fas fa-arrow-left" alt="Arrow left"></i> + <span>Next</span> + </a> + </span> + + <span class="index"> + <a href="https://blog.luevano.xyz" alt="Index"> + <i class="fas fa-home" alt="Home"></i> + <span>Index</span> + </a> + </span> + + <span class="previous"> + <a href="https://blog.luevano.xyz/a/devs_android_me_trozaron.html" alt="Previous"> + <i class="fas fa-arrow-right" alt="Arrow right"></i> + <span>Previous</span> + </a> + </span> +</div> + + + <hr> + <div class="article-info"> + <p>By David Luévano</p> + <p>Created: Sun, May 15, 2022 @ 22:40 UTC</p> + <p>Modified: Sun, May 22, 2022 @ 00:24 UTC</p> + <div class="article-tags"> + <p>Tags: +<a href="https://blog.luevano.xyz/tag/@english.html">english</a>, <a href="https://blog.luevano.xyz/tag/@short.html">short</a>, <a href="https://blog.luevano.xyz/tag/@tools.html">tools</a> </p> +</div> + + </div> + </main> + + <footer> +<span> + <i class="fas fa-address-card" alt="Contact"></i> + <a href="https://blog.luevano.xyz/contact.html">Contact</a> +</span> + +<span> + <i class="fas fa-donate" alt="Donate"></i> + <a href="https://blog.luevano.xyz/donate.html">Donate</a> +</span> + +<span> + <i class="fas fa-rss" alt="RSS"></i> + <a target="_blank" href="https://blog.luevano.xyz/rss.xml">RSS</a> +</span> + +<br> +<span class="created-with"> + <i class="fas fa-hammer" alt="Hammer"></i> + Created with <a href="https://github.com/luevano/pyssg">pyssg</a> +</span> + +<br> +<span class="copyright"> + Copyright <i class="far fa-copyright" alt="Copyright"></i> 2023 David Luévano Alvarado +</span> + + </footer> + </body> +</html>

This is supposed to work between two servers and one client: a server in charge of creating, signing and verifying the certificates, a server with the OpenVPN service running and the client making the request.</p> +<p>This is supposed to work something like: 1) a client wants to use the VPN service, so it creates a requests and sends it to the signing server, 2) this server checks the requests and signs the request, returning the certificates to both the VPN service and the client and 3) the client can now connect to the VPN service using the signed certificate which the OpenVPN server knows about. In a nutshell, I’m no expert.</p> +<p>… but, to be honest, all of this is a hassle and (in my case) I want something simple to use and manage. So I’m gonna do all on one server and then just give away the configuration file for the clients, effectively generating files that anyone can run and will work, meaning that you need to be careful who you give this files (it also comes with a revoking mechanism, so no worries).</p> +<p>This is done with <a href="https://wiki.archlinux.org/title/Easy-RSA">Easy-RSA</a>.</p> +<p>Install the <code>easy-rsa</code> package:</p> +<pre><code class="language-sh">pacman -S easy-rsa +</code></pre> +<p>Initialize the PKI and generate the CA keypair:</p> +<pre><code class="language-sh">cd /etc/easy-rsa +easyrsa init-pki +easyrsa build-ca nopass +</code></pre> +<p>Create the server certificate and private key (while in the same directory):</p> +<pre><code class="language-sh">EASYRSA_CERT_EXPIRE=3650 easyrsa build-server-full server nopass +</code></pre> +<p>Where <code>server</code> is just a name to identify your server certificate keypair, I just use <code>server</code> but could be anything (like <code>luevano.xyz</code> in my case).</p> +<p>Create the client revocation list AKA CRL (will be used later, but might as well have it now):</p> +<pre><code class="language-sh">EASYRSA_CRL_DAYS=3650 easyrsa gen-crl +</code></pre> +<p>After this we should have 6 new files:</p> +<pre><code>/etc/easy-rsa/pki/ca.crt +/etc/easy-rsa/pki/private/ca.key +/etc/easy-rsa/pki/issued/server.crt +/etc/easy-rsa/pki/reqs/server.req +/etc/easy-rsa/pki/private/server.key +/etc/easy-rsa/pki/crl.pem +</code></pre> +<p>It is recommended to copy some of these files over to the <code>openvpn</code> directory, but I prefer to keep them here and just change some of the permissions:</p> +<pre><code class="language-sh">chmod o+rx pki +chmod o+rx pki/ca.crt +chmod o+rx pki/issued +chmod o+rx pki/issued/server.crt +chmod o+rx pki/private +chmod o+rx pki/private/server.key +chown nobody:nobody pki/crl.pem +chmod o+r pki/crl.pem +</code></pre> +<p>Now, go to the <code>openvpn</code> directory and create the required files there:</p> +<pre><code class="language-sh">cd /etc/openvpn/server +openssl dhparam -out dh.pem 2048 +openvpn --genkey secret ta.key +</code></pre> +<p>That’s it for the PKI stuff and general certificate configuration.</p> +<h2 id="openvpn">OpenVPN</h2> +<p><a href="https://wiki.archlinux.org/title/OpenVPN">OpenVPN</a> is a robust and highly flexible VPN daemon, that’s pretty complete feature wise.</p> +<p>Install the <code>openvpn</code> package:</p> +<pre><code class="language-sh">pacman -S openvpn +</code></pre> +<p>Now, most of the stuff is going to be handled by (each, if you have more than one) server configuration.

Read each and every line, you might want to change some stuff (like the logging), specially the first line which is your server public IP.</p> +<p>Now, we need to enable <em>packet forwarding</em> (so we can access the web while connected to the VPN), which can be enabled on the interface level or globally (you can check the different options with <code>sysctl -a | grep forward</code>). I’ll do it globally, run:</p> +<pre><code class="language-sh">sysctl net.ipv4.ip_forward=1 +</code></pre> +<p>And create/edit the file <code>/etc/sysctl.d/30-ipforward.conf</code>:</p> +<pre><code>net.ipv4.ip_forward=1 +</code></pre> +<p>Now we need to configure <code>ufw</code> to forward traffic through the VPN. Append the following to <code>/etc/default/ufw</code> (or edit the existing line):</p> +<pre><code>... +DEFAULT_FORWARD_POLICY="ACCEPT" +... +</code></pre> +<p>And change the <code>/etc/ufw/before.rules</code>, appending the following lines after the header <strong>but before the *filter line</strong>:</p> +<pre><code>... +# NAT (Network Address Translation) table rules +*nat +:POSTROUTING ACCEPT [0:0] + +# Allow traffic from clients to the interface +-A POSTROUTING -s 10.8.0.0/24 -o interface -j MASQUERADE + +# do not delete the "COMMIT" line or the NAT table rules above will not be processed +COMMIT + +# Don't delete these required lines, otherwise there will be errors +*filter +... +</code></pre> +<p>Where <code>interface</code> must be changed depending on your system (in my case it’s <code>ens3</code>, another common one is <code>eth0</code>); I always check this by running <code>ip addr</code> which gives you a list of interfaces (the one containing your server public IP is the one you want, or whatever interface your server uses to connect to the internet):</p> +<pre><code>... +2: ens3: <SOMETHING,SOMETHING> bla bla + link/ether bla:bla + altname enp0s3 + inet my.public.ip.addr bla bla +... +</code></pre> +<p>And also make sure the <code>10.8.0.0/24</code> matches the subnet mask specified in the <code>server.conf</code> file (in this example it matches). You should check this very carefully, because I just spent a good 2 hours debugging why my configuration wasn’t working, and this was te reason (I could connect to the VPN, but had no external connection to the web).</p> +<p>Finally, allow the OpenVPN port you specified (in this example its <code>1194/udp</code>) and reload <code>ufw</code>:</p> +<pre><code class="language-sh">ufw allow 1194/udp comment "OpenVPN" +ufw reload +</code></pre> +<p>At this point, the server-side configuration is done and you can start and enable the service:</p> +<pre><code class="language-sh">systemctl start openvpn-server@server.service +systemctl enable openvpn-server@server.service +</code></pre> +<p>Where the <code>server</code> after <code>@</code> is the name of your configuration, <code>server.conf</code> without the <code>.conf</code> in my case.</p> +<h3 id="create-client-configurations">Create client configurations</h3> +<p>You might notice that I didn’t specify how to actually connect to our server. For that we need to do a few more steps. We actually need a configuration file similar to the <code>server.conf</code> file that we created.</p> +<p>The real way of doing this would be to run similar steps as the ones with <code>easy-rsa</code> locally, send them to the server, sign them, and retrieve them. Nah, we’ll just create all configuration files on the server as I was mentioning earlier.</p> +<p>Also, the client configuration file has to match the server one (to some degree), to make this easier you can create a <code>client-common</code> file in <code>/etc/openvpn/server</code> with the following content:</p> +<pre><code>client +dev tun +remote 1.2.3.4 1194 udp # change this to match your ip and port +resolv-retry infinite +nobind +persist-key +persist-tun +remote-cert-tls server +auth SHA512 +verb 3 +</code></pre> +<p>Where you should make any changes necessary, depending on your configuration.</p> +<p>Now, we need a way to create and revoke new configuration files. For this I created a script, heavily based on one of the links I mentioned at the beginning, by the way. You can place these scripts anywhere you like, and you should take a look before running them because you’ll be running them as root.</p> +<p>In a nutshell, what it does is: generate a new client certificate keypair, update the CRL and create a new <code>.ovpn</code> configuration file that consists on the <code>client-common</code> data and all of the required certificates; or, revoke an existing client and refresh the CRL.

And, actually at the time of writing this entry, I’m configuring the web server again on a new VPS instance, so this is going to be fresh.</p> +<p>As a side note, (((i use arch btw))) so everything here es aimed at an Arch Linux distro, and I’m doing everything on a VPS. Also note that most if not all commands here are executed with root privileges.</p> +<h2 id="prerequisites">Prerequisites</h2> +<p>You will need two things:</p> +<ul> +<li>A domain name (duh!). I got mine on <a href="https://www.epik.com/?affid=da5ne9ru4">Epik</a> (affiliate link, btw).<ul> +<li>With the corresponding <strong>A</strong> and <strong>AAA</strong> records pointing to the VPS’ IPs (“A” record points to the ipv4 address and “AAA” to the ipv6, basically). I have three records for each type: empty one, “www” and “*” for a wildcard, that way “domain.name”, “www.domain.name”, “anythingelse.domain.name” point to the same VPS (meaning that you can have several VPS for different sub-domains).</li> +</ul> +</li> +<li>A VPS or somewhere else to host it. I’m using <a href="https://www.vultr.com/?ref=8732849">Vultr</a> (also an affiliate link).<ul> +<li>With <code>ssh</code> already configured both on the local machine and on the remote machine.</li> +<li>Firewall already configured to allow ports 80 (HTTP) and 443 (HTTPS). I use <code>ufw</code> so it’s just a matter of doing <code>ufw allow 80,443/tcp</code> as root and you’re golden.</li> +<li><code>cron</code> installed if you follow along (you could use <code>systemd</code> timers, or some other method you prefer to automate running commands every X time).</li> +</ul> +</li> +</ul> +<h2 id="nginx">Nginx</h2> +<p><a href="https://wiki.archlinux.org/title/Nginx">Nginx</a> is a web (HTTP) server and reverse proxy server.</p> +<p>You have two options: <code>nginx</code> and <code>nginx-mainline</code>. I prefer <code>nginx-mainline</code> because it’s the “up to date” package even though <code>nginx</code> is labeled to be the “stable” version. Install the package and enable/start the service:</p> +<pre><code class="language-sh">pacman -S nginx-mainline +systemctl enable nginx.service +systemctl start nginx.service +</code></pre> +<p>And that’s it, at this point you can already look at the default initial page of Nginx if you enter the IP of your server in a web browser. You should see something like this:</p> +<figure id="__yafg-figure-1"> +<img alt="Nginx welcome page" src="images/b/notes/nginx/nginx_welcome_page.png" title="Nginx welcome page"> +<figcaption>Nginx welcome page</figcaption> +</figure> +<p>As stated in the welcome page, configuration is needed, head to the directory of Nginx:</p> +<pre><code class="language-sh">cd /etc/nginx +</code></pre> +<p>Here you have several files, the important one is <code>nginx.conf</code>, which as its name implies, contains general configuration of the web server. If you peek into the file, you will see that it contains around 120 lines, most of which are commented out and contains the welcome page server block. While you can configure a website in this file, it’s common practice to do it on a separate file (so you can scale really easily if needed for mor websites or sub-domains).</p> +<p>Inside the <code>nginx.conf</code> file, delete the <code>server</code> blocks and add the lines <code>include sites-enabled/*;</code> (to look into individual server configuration files) and <code>types_hash_max_size 4096;</code> (to get rid of an ugly warning that will keep appearing) somewhere inside the <code>http</code> block. The final <code>nginx.conf</code> file would look something like (ignoring the comments just for clarity, but you can keep them as side notes):</p> +<pre><code class="language-nginx">worker_processes 1; + +events { + worker_connections 1024; +} + +http { + include sites-enabled/*; + include mime.types; + default_type application/octet-stream; + + sendfile on; + + keepalive_timeout 65; + + types_hash_max_size 4096; +} +</code></pre> +<p>Next, inside the directory <code>/etc/nginx/</code> create the <code>sites-available</code> and <code>sites-enabled</code> directories, and go into the <code>sites-available</code> one:</p> +<pre><code class="language-sh">mkdir sites-available +mkdir sites-enabled +cd sites-available +</code></pre> +<p>Here, create a new <code>.conf</code> file for your website and add the following lines (this is just the sample content more or less):</p> +<pre><code class="language-nginx">server { + listen 80; + listen [::]:80; + + root /path/to/root/directory; + server_name domain.name another.domain.name; + index index.html anotherindex.otherextension; + + location /{ + try_files $uri $uri/ =404; + } +} +</code></pre> +<p>That could serve as a template if you intend to add more domains.</p> +<p>Note some things:</p> +<ul> +<li><code>listen</code>: we’re telling Nginx which port to listen to (IPv4 and IPv6, respectively).</li> +<li><code>root</code>: the root directory of where the website files (<code>.html</code>, <code>.css</code>, <code>.js</code>, etc. files) are located. I followed Luke’s directory path <code>/var/www/some_folder</code>.</li> +<li><code>server_name</code>: the actual domain to “listen” to (for my website it is: <code>server_name luevano.xyz www.luevano.xyz;</code> and for this blog is: <code>server_name blog.luevano.xyz www.blog.luevano.xyz;</code>).</li> +<li><code>index</code>: what file to serve as the index (could be any <code>.html</code>, <code>.htm</code>, <code>.php</code>, etc. file) when just entering the website.</li> +<li><code>location</code>: what goes after <code>domain.name</code>, used in case of different configurations depending on the URL paths (deny access on <code>/private</code>, make a proxy on <code>/proxy</code>, etc).<ul> +<li><code>try_files</code>: tells what files to look for.</li> +</ul> +</li> +</ul> +<p>Then, make a symbolic link from this configuration file to the <code>sites-enabled</code> directory:</p> +<pre><code class="language-sh">ln -s /etc/nginx/sites-available/your_config_file.conf /etc/nginx/sites-enabled +</code></pre> +<p>This is so the <code>nginx.conf</code> file can look up the newly created server configuration. With this method of having each server configuration file separate you can easily “deactivate” any website by just deleting the symbolic link in <code>sites-enabled</code> and you’re good, or just add new configuration files and keep everything nice and tidy.</p> +<p>All you have to do now is restart (or enable and start if you haven’t already) the Nginx service (and optionally test the configuration):</p> +<pre><code class="language-sh">nginx -t +systemctl restart nginx +</code></pre> +<p>If everything goes correctly, you can now go to your website by typing <code>domain.name</code> on a web browser. But you will see a “404 Not Found” page like the following (maybe with different Nginx version):</p> +<figure id="__yafg-figure-2"> +<img alt="Nginx 404 Not Found page" src="images/b/notes/nginx/nginx_404_page.png" title="Nginx 404 Not Found page"> +<figcaption>Nginx 404 Not Found page</figcaption> +</figure> +<p>That’s no problem, because it means that the web server it’s actually working. Just add an <code>index.html</code> file with something simple to see it in action (in the <code>/var/www/some_folder</code> that you decided upon). If you keep seeing the 404 page make sure your <code>root</code> line is correct and that the directory/index file exists.</p> +<p>I like to remove the <code>.html</code> and trailing <code>/</code> on the URLs of my website, for that you need to add the following <code>rewrite</code> lines and modify the <code>try_files</code> line (for more: <a href="https://www.seancdavis.com/blog/remove-html-extension-and-trailing-slash-in-nginx-config/">Sean C. Davis: Remove HTML Extension And Trailing Slash In Nginx Config</a>):</p> +<pre><code class="language-nginx">server { + ... + rewrite ^(/.*)\.html(\?.*)?$ $1$2 permanent; + rewrite ^/(.*)/$ /$1 permanent; + ... + try_files $uri/index.html $uri.html $uri/ $uri =404; + ... +</code></pre> +<h2 id="certbot">Certbot</h2> +<p><a href="https://wiki.archlinux.org/title/Certbot">Certbot</a> is what provides the SSL certificates via <a href="https://letsencrypt.org/">Let’s Encrypt</a>.</p> +<p>The only “bad” (bloated) thing about Certbot, is that it uses <code>python</code>, but for me it doesn’t matter too much. You may want to look up another alternative if you prefer. Install the packages <code>certbot</code> and <code>certbot-nginx</code>:</p> +<pre><code class="language-sh">pacman -S certbot certbot-nginx +</code></pre> +<p>After that, all you have to do now is run <code>certbot</code> and follow the instructions given by the tool:</p> +<pre><code class="language-sh">certbot --nginx +</code></pre> +<p>It will ask you for some information, for you to accept some agreements and the names to activate HTTPS for. Also, you will want to “say yes” to the redirection from HTTP to HTTPS. And that’s it, you can now go to your website and see that you have HTTPS active.</p> +<p>Now, the certificate given by <code>certbot</code> expires every 3 months or something like that, so you want to renew this certificate every once in a while. Using <code>cron</code>, you can do this by running:</p> +<pre><code class="language-sh">crontab -e +</code></pre> +<p>And a file will be opened where you need to add a new rule for Certbot, just append the line: <code>1 1 1 * * certbot renew</code> (renew on the first day of every month) and you’re good. Alternatively use <code>systemd</code> timers as stated in the <a href="https://wiki.archlinux.org/title/Certbot#Automatic_renewal">Arch Linux Wiki</a>.</p> +<p>That’s it, you now have a website with SSL certificate.</p> + + <div class="page-nav"> + <span class="next"> + <a href="https://blog.luevano.xyz/a/mail_server_with_postfix.html" alt="Next"> + <i class="fas fa-arrow-left" alt="Arrow left"></i> + <span>Next</span> + </a> + </span> + + <span class="index"> + <a href="https://blog.luevano.xyz" alt="Index"> + <i class="fas fa-home" alt="Home"></i> + <span>Index</span> + </a> + </span> + + <span class="previous"> + <a href="https://blog.luevano.xyz/a/el_blog_ya_tiene_timestamps.html" alt="Previous"> + <i class="fas fa-arrow-right" alt="Arrow right"></i> + <span>Previous</span> + </a> + </span> +</div> + + + <hr> + <div class="article-info"> + <p>By David Luévano</p> + <p>Created: Fri, Mar 19, 2021 @ 02:58 UTC</p> + <p>Modified: Tue, Jun 08, 2021 @ 07:27 UTC</p> + <div class="article-tags"> + <p>Tags: +<a href="https://blog.luevano.xyz/tag/@english.html">english</a>, <a href="https://blog.luevano.xyz/tag/@server.html">server</a>, <a href="https://blog.luevano.xyz/tag/@tools.html">tools</a>, <a href="https://blog.luevano.xyz/tag/@tutorial.html">tutorial</a> </p> +</div> + + </div> + </main> + + <footer> +<span> + <i class="fas fa-address-card" alt="Contact"></i> + <a href="https://blog.luevano.xyz/contact.html">Contact</a> +</span> + +<span> + <i class="fas fa-donate" alt="Donate"></i> + <a href="https://blog.luevano.xyz/donate.html">Donate</a> +</span> + +<span> + <i class="fas fa-rss" alt="RSS"></i> + <a target="_blank" href="https://blog.luevano.xyz/rss.xml">RSS</a> +</span> + +<br> +<span class="created-with"> + <i class="fas fa-hammer" alt="Hammer"></i> + Created with <a href="https://github.com/luevano/pyssg">pyssg</a> +</span> + +<br> +<span class="copyright"> + Copyright <i class="far fa-copyright" alt="Copyright"></i> 2023 David Luévano Alvarado +</span> + + </footer> + </body> +</html>
