About

Unison is a great tool to synchronize files between different computer systems, supporting various UNIX platforms including Linux and also Microsoft Windows.

Prerequesites

• dropbear SSH server installed and running on the Nokia 770, see http://maemo.org/maemowiki/InstallSsh
• if you want to start Unison on the Nokia 770 itself (instead of just using it remotely by starting Unison on your desktop machine and connecting via SSH), you also need the X Terminal Simulator from http://770.fs-security.com/xterm/

Installation

Download the attached Debian "arm" package for the older ITOS2005 operating system or the new "armel" package for the newer ITOS2006 (released end of June 2006) and install it with the Application Installer.

Usage

See the Unison manual for details.

Quick HowTo to synchronizing your $HOME on the Nokia 770

(click pictures to enlarge them)

Install Unison on the Nokia 770 and Unison with GTK support on your desktop machine. Create a directory (e.g. ~/Nokia770) on your desktop machine that will hold your sync-ed hierarchy.

Start Unison on the desktop with

unison-gtk

choose "Create new profile" and give it a whatever name you like, e.g. Nokia770.

Double-click the new profile, select your local directory (in my case /home/spiney/Nokia770)

for the second directory choose SSH, insert hostname or IP address in the Hosts field (and the username "user" in the User field in case you do not have a special Nokia770 configuration in ~/.ssh/config)

Ignore the warning about first sync, because it is the first time you synchronize and enjoy!

Note: to avoid Unison trying to synchronize it's own status directory on the Nokia770 (which will never be in sync because every update will change it), I suggest adding the following line to ~/.unison/<profilename>.prf:

ignore = Name .unison

Feel free to just synchronize the MyDocs directory by providing "MyDocs" when specifying the second directory.

Todo

Built a working GTK-enabled package, as in: find the reason why the application segfaults after a couple of seconds when built with GTK support.
