Set up Owncloud for personal data management and Android sync

If privacy is a concern and you’d be feeling better to host your own CalDav and CarDav (calendar and contact) data but still would like to access it from your smartphone and web Owncloud is a straightforward open-source tool to use.

Remark: hosting your email would only be a possibility if high availability server hardware and internet connection is available for use.

Register a cheap domain with Namecheap and configure DynamicDNS
Add this script to CRON to regularly update Namecheap on your IP
address
- Do this on the Internet interface of your host or OpenWRT router
- Use this script

urllib2.urlopen("http://dynamicdns.park-your-domain.com/update?host=%s&domain=%s&password=%s" % ("subdomain", "yourdomain.com", "hash.by.namecheap..82d9365e23be655"))

Set it in crontab

crontab -e
#Add this to run IP update script every 0:05
        5 0 * * * /path/to/script

Use an Ubuntu Server (14.04 64)
