Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I have some services running on my PC at home. It is behind a router, so it has a local ip, like 192.168.*.*. My router is registered at no-ip.com, so hopefully
I would like to connect to my pc from my workspace. It is a big company using proxy, so I cannot have direct connection.
Also I would like to have a secure connection.
Do you have any idea to realize it? Should I try VNC, ssh tunnel, or ?.
Generally you just need to set up a port forwarding rule in your home router to redirect any incoming requests on the desired port to the machine's local IP. You can use SSH, VNC, or any other services that listen on a dedicated port.
The network setup at your office typically doesn't matter unless you're trying to connect in reverse (home to work).
If the company is smart they disabled almost everything. I'd consider barracudaserver and use https. Every once in a while they offer it free.
As above you have to learn how to NAT your home modem/router. Some have a build in app that can connect to DDNS services and change dns name to ip when you dynamic ip changes. If not then you'd need a client at home to change no-ip's dns entry. Better to nat the ports to the box instead of that other setting. I forget that name, but it opens all outside ports to the internal lan.
Distribution: Debian Sid AMD64, Raspbian Wheezy, Slackware Current AMD64, various VMs
I think the "DMZ" in the NAT+router is supposed to open the box to the internet but my experience was that it didn't seem to work and I ended up forwarding the ports I needed to the machine on the LAN. You also need to reserve an IP address for the machine you'll be connecting to on the router.
One place I worked I couldn't even SSH on port 80 to my home box though (I tried non-standard and default) so ended up giving up and using my phone to connect to home instead.
