 <p>Finally I managed to access it from my computer. I had to modify the configuration file for the operation center, located in <code>/etc/opscenter/opscenterd.conf</code> (only for package installation):</p> <pre><code>[webserver] port = 8888 interface = 127.0.0.1 </code></pre> <p>By default the webserver accepts requests only from the localhost. Probably it won't be the best option, but since the operation center allows to configure users, I set <code>interface = 0.0.0.0</code>, allowing any host to contact it. </p>
