It seems my ADSL provider is not changing the IP, so I decided to host some sites at home. Here I copy the apache config for this blog, now running from an old Dell laptop:
$ cat sites-available/fasani.org

<VirtualHost *>
ServerName es.fasani.org

ServerAlias en.fasani.org
DocumentRoot /home/www/fasani.org/httpdocs/

<Directory /home/www/fasani.org/httpdocs >
Options Indexes Includes MultiViews FollowSymLinks
AllowOverride All
Order allow,deny
Allow from all
</Directory>

Customlog /home/www/logs/fasani.org.log combined
Errorlog /home/www/logs/fasani.err.log

</VirtualHost>
