Tonido was remote access and home server[1][2] software for network-attached storage.

This allowed access to files stored on the computer, including music and videos, to any computing device connected to the Internet in possession of login credentials.

Data was by default transmitted via Tonido's servers, with no port forwarding required, but could be transmitted without using Tonido's servers by setting up port forwarding.

Tonido stored all user information including login credentials locally, enabling login into Tonido software without the requirement of an internet connection.

[3] Tonido ran on x86, ARM, PowerPC and MIPS architectures, and was available as binary packages for popular Linux distributions such as Ubuntu, Fedora, and OpenSUSE, and for Mac OS X and Windows.
