Windows 7 Ultimate + OpenSUSE 11.2 (Seamless)
This is a demonstration of Windows 7 Ultimate as a host operating system with a custom OpenSUSE 11.2 (Gnome) installation on top in seamless application mode running in a Virtualbox with paravirtualization. What you see in this video is how it looks like even on a slow-ass notebook and what makes it interesting. Sorry for lame video quality, I used my mobile to film it because I was too lazy to pollute my host OS with questionable shareware that might probably not be able to film all screen contents because of the video driver wizardry. Some interesting facts about this installation: - The virtual machine autostarts into console-only window mode, effectively giving you a full-featured internet server and firewall that consumes only 24mb of ram. It uses bridged networking to access the internet. Windows can be instructed via a single click to re-route traffic through linux, effectively putting it behind the virtual machine for maximum security and features (e.g. traffic shaping, source-based routing), expanding your Windows 7 computer to an enterprise-grade internet router/server at the same time. - When entering 'gui' at the linux login prompt, an Xorg server with Gnome will be started, waiting for you to hit RSTRG+L to go into seamless application mode, enabling *nix applications for your windows desktop with full 3D and Sound support. When done using gnome apps, the Xorg server can be unloaded again to free massive ram and giving you back the console-only virtual internet server in window mode. - Usage of full compiz-fusion effects are possible. However in seamless mode, cubes and other virtual desktop fancyness are not used so that there is no interference with your active and visible windows desktop. Actually, you don't see the linux desktop at all, only the taskbar, linux will integrate into your windows desktop (as demonstrated in the video). Compiz effects will be used for application windows only. You need to hack video drivers and Xorg to make Compiz work with the latest version of Virtualbox and OpenSUSE 11.2, it's been a damn pain in the ass. - After shutting down the virtual machine, the Windows 7 host OS can be instructed via another single click to route internet traffic directly again, putting it back into normal connectivity mode. If Windows 7 is needed to connect to the internet (e.g. WLAN), the virtual machine can be run in NAT mode (no router features possible, in that case this installation can be instructed to boot directly into seamless gnome by issueing a simple command to enable or disable the autostart of the gnome desktop).

pfSense NAT setup for Game Server
This is a remake of a video I made earlier, I had some wrong information so I am redoing it. This fixes the problem of game servers getting random ports while behind pfSense. It is a simple fix, just a few settings that need tweaked. For some reason, an extra 4 minutes of black was added, not really sure why.

Basic Squid Proxy Server Tutorial Part 3 of 3
Final step to configure and share Internet connection with Squid Proxy on a server with 2 NIC's. We explain a little about iptables so it can jump and masquerade the workstations. Also, 2 things I forgot to mention which I added an annotation at the end of the video 1. Pls. don't forget to edit your /etc/squid/squid.conf and put: http_port 3128 transparent 3128 is the Squid's port number. Transparent means you don't have to manually specify the proxy server on each workstation so that if you have 20 clients you don't have to go to each one of them. 2. Pls. also make sure that your client's /etc/resolv.conf is pointing to your router or dns-nameserver that is add this line anywhere in that file. nameserver 192.168.0.254 192.168.0.254 - is the router's IP address. Good luck!
