Turn Your Retired Android Smartphone Into a Server With “Servers Ultimate” Application
If you were an early adopter of Android and have one of the first devices with this OS at home, you may be lucky enough to play with it and turn it into a server. That’s what XDA Forum member Themuzz did, when he coded an app called Servers Ultimate, that allows an Android phone to run supported server types. That’s how you can turn a Nexus One into a mobile server.
The supported server types include DLNA, DNS, DDNS, Email (POP3 and SMTP), FTP(S), Proxy (tunneling), SMS Gateway, Time (NTP or TP), HTTP(S) and WebDAV (secure). Server Ultimate can be used to stream media to your devices using DLNA, or to create an email server, perhaps setup a proxy server. You can also share files with a FTP or configure your very own web server. The cool thing is that you can also run multiple instances of the same server at the same time.
DDNS makes sure that the servers stay online and are accessible. I have a thing to say here: considering how vulnerable Android actually is in front of malware, I’d think twice before using a handset with this OS for a server that holds your business documents. Keep that in mind. Details on this XDA thread.
