    <p>You seem to be mistaking MusicBrainz-Server to be only the database. What's running on port 5000 is the Web Server. You can access <code>http://10.16.65.250:5000</code> in the browser.</p> <p>Postgres is also running, but listens on <code>localhost:5432</code>. This works:</p> <pre><code>import psycopg2 conn = psycopg2.connect(database="musicbrainz_db", user="musicbrainz", password="musicbrainz", port="5432", host="localhost") print("Connection established") </code></pre> <p>In order to make postgres listen to more than localhost you need to change <code>listen_addresses</code> in <code>/etc/postgresql/9.1/main/postgres.conf</code> and make an entry for your (client) host or network in <code>/etc/postgresql/9.1/main/pg_hba.conf</code>.</p> <p>My VM is running in a 192.168.1.0/24 network so I set <code>listen_addresses='*'</code> in postgres.conf and in pg_hab.conf:</p> <pre><code>host all all 192.168.1.0/24 trust </code></pre> <p>I can now connect from my local network to the DB in the VM.</p> <hr> <p>Depending on what you actually need, you might not want to connect to the MusicBrainz Server via postgres. There is a <a href="http://musicbrainz.org/doc/Development/XML_Web_Service/Version_2" rel="nofollow">MusicBrainz web service</a> you can access in the VM. Example: <code>http://10.16.65.250:5000/ws/2/artist/c5c2ea1c-4bde-4f4d-bd0b-47b200bf99d6</code>. In that case you might be interested in a library to process the data: <a href="http://python-musicbrainzngs.readthedocs.org/" rel="nofollow">python-musicbrainzngs</a>.</p> <p>EDIT: You need to set <code>musicbrainzngs.set_hostname("10.16.65.250:5000")</code> for musicbrainzngs to connect to your local VM.</p>

    1. COI can reproduce psycopg2 blocking when trying port 5000. This doesn't work since 5000 runs the HTTP protocol, but psycopg2 shouldn't be blocking, but rather give an exception.

    2. COThis was exactly my problem, thank you very much! Regarding the MusicBrainz web service, it seems that the library python-musicbrainz-ngs connects only to the "main" musicbrainz web service and I don't know if I can redirected to the local one. In fact, the main database has a limitation of one web service call per second and, in my case, this would not be enough.

    3. COPlease have a look at [musicbrainzngs.set_hostname()](https://python-musicbrainz-ngs.readthedocs.org/en/latest/api/#musicbrainzngs.set_hostname). You can also connect to a local MusicBrainz Server.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
