In one of my previous post I made a tutorial how to bypass corporate firewalls and gain access into your office computer. It work well if you are at your home and you need ssh access (or any other service) to your office computer. However if the situation is reversed, and you need to access some outside service which your firewall is blocking then you would use this little tutorial with explanations. Although all this is covered in the ssh man pages, one always learn best by real life examples, so here I'll try to cover few of them.

There are tons of reasons why would one want to create a rsync server. For example you wish to backup your data to a remote server but you don't want to backup everything every time.
rsync is an open source utility that provides fast incremental file transfer. rsync is freely available under the GNU General Public License and is currently being maintained by Wayne Davison.
Synergy is a nifty tool for cross platform clipboard, keyboard and mouse sharing. It's reasonably easy to configure synergy server for use with multiple synergy clients.
Doing so will spare you some time while working on multiple computers at your desk at once. I use it at office to connect my laptop's and office computer mouse, keyboard and clipboard and thus reducing or completely eliminating need to lean over my laptop every time I need to use it. Anyway, most of the people use it with quicksynergy wrapper allowing even easier setup, but what the synergy lack is a means of authentication and security in data transfers. I'll try to guide you how to make a secure synergy setup on untrusted networks.
Probably lots of you are behind some sort of very restrictive corporate firewall. Unable to access your office pc from home because of firewall policies. In normal cases this scenario is more than welcomed. No outsiders should be allowed to access internal parts of secure network! Ideally companies will setup secure VPN access allowing its employees to access their work computers and do some work remotely. What if you aren't one of the lucky ones having such option? You desperately need to access your office pc?
Using ssh and its functionality should be a second nature to all Linux sysadmins, for some users some aspects of ssh are still a mystery, so let's shed some light on it. Here you will not learn basics shell commands and usage, I will simply try to explain usage of ssh protocol itself, and it benefits. How to use ssh, how to setup keys, how to use ssh agent that will enable some extra functionality for programs like scp, rsync, etc.
