You can check for errors using <code>prosodyctl check</code>. As a final note, I should add that if you are using a VPS you probably have +a firewall working. There are some ports that need to be forwarded: 5280, 5281, 5222, 5322, 5000, 3478. If you are not using a firewall I recommend you using +<code>ufw</code> and start from there.</p> +<p>Also, that this configuration is very personal. You can add more components (for example multichat groups). For that you should +RTFM, which is always ideal.</p> +<ul> +<li><a href="https://prosody.im/doc">Prosody Docs</a></li> +</ul> + + </div> + + </section> + </div> + <footer class="page__footer"><ul class="buttons"> + + <li> + <a href="https://drainerdomain.xyz"><img src="/buttons/drainerdomain2.gif" alt="drainerdomain"></a> + </li> + + <li> + <a href="https://landchad.net"><img src="/buttons/landchad.gif" alt="LandChud"></a> + </li> + + <li> + <a href="https://tomfasano.net"><img src="/buttons/tomfasano.gif" alt="Tom Fasano"></a> + </li> + + <li> + <a href="https://neovim.io"><img src="/buttons/neovim.gif" alt="neovim"></a> + </li> + + <li> + <a href="https://gohugo.io"><img src="/buttons/hugo.gif" alt="neovim"></a> + </li> + + <li> + <a href="https://wiby.org"><img src="/buttons/wiby.gif" alt="wiby"></a> + </li> + + <li> + <a href="https://gnu.org"><img src="/buttons/gnu-linux.png" alt="gnu"></a> + </li> + + <li> + <a href="https://stephenvk.xyz"><img src="/buttons/stephenvk.gif" alt="stephenvk"></a> + </li> + + <li> + <a href="https://canoemail.net"><img src="/buttons/canoemail.gif" alt="canoemail services"></a> + </li> + + <li> + <a href="https://heaventreey.xyz"><img src="/buttons/heaventree.gif" alt="heaventree webring"></a> + </li> + + <li> + <a href="https://spyware.neocities.org"><img src="/buttons/spywaredotneocities.png" alt="spywarewatchdog"></a> + </li> + + <li> + <a href="https://getmonero.org"><img src="/buttons/getmonero.gif" alt="Get Monero"></a> + </li> + + <li> + <a href="https://digdeeper.neocities.org"><img src="/buttons/digdeeper.png" alt="Digdeeper"></a> + </li> + +</ul> +</footer> + </body> + +</html> |
