Running a network doesn’t mean you have all the answers

. Networking is a complex subject with reams of reference material that’s difficult to keep straight, much less remember. If you want a book that lays out the steps for specific tasks, that clearly explains the commands and configurations, and does not tax your patience with endless ramblings and meanderings into theory and obscure RFCs, this is the book for you.

You will find recipes for:

* Building a gateway, firewall, and wireless access point on a Linux network
* Building a VoIP server with Asterisk
* Secure remote administration with SSH
* Building secure VPNs with OpenVPN, and a Linux PPTP VPN server
* Single sign-on with Samba for mixed Linux/Windows LANs
* Centralized network directory with OpenLDAP
* Network monitoring with Nagios or MRTG
* Getting acquainted with IPv6
* Setting up hands-free networks installations of new systems
* Linux system administration via serial console

And a lot more. Each recipe includes a clear, hands-on solution with tested code, plus a discussion on why it works. When you need to solve a network problem without delay, and don’t have the time or patience to comb through reference books or the Web for answers, Linux Networking Cookbook gives you exactly what you need.

About the Author
Carla Schroder is a self-taught Linux and Windows sysadmin, who laid hands on her first computer around her 37th birthday. Her first PC was a Macintosh LC II. Next came an IBM-clone, a 386sx running MS-DOS 5 and Windows 3.1, with a 14″ color display, which was adequate for many pleasant hours of DOOM play. Then around 1997 she discovered Red Hat 5.0, and had a whole new world to explore.

Somewhere along the way she found herself doing freelance consulting for small businesses and home users, supporting both Linux and Windows users, and integrating Linux and Windows on the LAN; primarily Linux servers and Windows clients. She is the author of the Linux Cookbook for O’Reilly, and writes Linux howtos for several computer publications.

Drifting a RC car is easy, you just need a suitable Drift Tyre made from hard compound for example PVC. Different from the foam Tyre which normally used for touring, drift Tyre is design not to grip much. I don’t want to talk much about Drifting technique here since I am still learning few basic term for example chamber, counter steer, lock diff and many more that related to rc drifting. I will update my knowledge here when I have time.

Lithium polymer or LiPo battery is the most suitable for rc drifting. I have 4000mah 7.4V Yeah Racing LiPo battery which can stand up to 45 minutes of drifting. But be careful LiPo battery need extra care from you. It easily get burned when exposed to heat or short circuit. LiPo battery also need suitable charger or balancer so it can operate at maximum rate. The charger that I am using now is Turnigy Accucel-6 50W 5A Balancer and Charger a compact charger satisfy all your lipo needs. I comes together with few charging leads including dean, T plug, crocodile clip, servo terminal for transmitter charger and also starter for nitro engine. I don’t really know how the hell I should use that starter it function like a glow plug starter. Just follow the instruction sheets and you are good to go.

My Turnigy Accucell With Orca Infinite LiPo battery

The charger functionality is quite similar to iMax b6 but the only different is Turnigy Accucell 6 have built in fan, which is is good to cool down internal circuit since one battery could take 1 hour plus to complete charging. The good thing about This charger is there are lot of protection scheme. Since lipo battery is dangerous, they have what i call “cell error protector” whenever I want to charge my lipo it will confirmed first the amount of cells that I am trying to charge. Besides it protect you from charging a reverse polarity battery. Lots of warning to protect the lipo and for your safety. What annoy me is the beeping sounds every time you push the button, but you can turn them off.

For the power supply unit I am using adaptor from SkyRc which provide 5A of current and 15V because the rating of Turnigy Accucell 6 is 5A current and 11V-18V. So I cannot charge my 5500mAh Orca Infinite using at 1C rate which is 5.5A because the limit is 5A, but that is not a problem it took only 1hour and 20 minutes to finished charging. I recommend you guys to charge the Lipo battery at 1C or lower to make your Lipo last for a long time. For example 4000mAh the suitable charging rate is 4.0A and remember to charge using balance charge. As a Lipo charger Accucell 6 did very good job for me. Never had a problem using it until now and it come with addon connector for temperature sensor(sold separately).

It has the latest face recognition technology, just touch a face on the LCD screen and the camcorder will save it in the memory. Sony HDR-CX500V and HDR-CX520V pre-installed with Navteq GPS software that will let user geo-tagging their video.
