Download | / | General Below you can download GNS3, a network simulator for making labs or topologies of routers (IOS, JunOS), firewalls (ASA, PIX) and hosts. It is particularly useful for training to Cisco certifications (CCNA, CCNP, CCIP, CCSP, CCVP or CCIE) or Juniper certifications (JNCIA, JNCIS or JNCIE). Thanks to VirtualBox integration, now even system engineers and administrators can take advantage of GNS3 to study Redhat (RHCE, RHCT), Microsoft (MSCE, MSCA), Novell (CLP) and many other vendor certifications. Windows New users to GNS3, it is recommended to download the all-in-one package below. GNS3 v0.8.6 all-in-one (installer for 32-bit and 64-bit which includes Dynamips, Qemu/Pemu, Putty, VPCS, WinPCAP and Wireshark)GNS3 v0.8.6 standalone 32-bit (archive that includes Dynamips, Pemu, Putty, VPCS)GNS3 v0.8.6 standalone 64-bit (Windows 64-bit only, archive that includes Dynamips, Pemu, Putty, VPCS) Mac OS X Linux Sources Other downloads Qemu & VirtualBox appliancesVPCS (Virtual PC simulator)
i-Net Media | Internet Media & IT Solutions Solar panel Photovoltaic solar panels absorb sunlight as a source of energy to generate direct current electricity. A photovoltaic (PV) module is a packaged, connected assembly of photovoltaic solar cells available in different voltages and wattages. Photovoltaic modules constitute the photovoltaic array of a photovoltaic system that generates and supplies solar electricity in commercial and residential applications. The most common application of solar energy collection outside agriculture is solar water heating systems.[1] Theory and construction[edit] A PV junction box is attached to the back of the solar panel and functions as its output interface. Module electrical connections are made in series to achieve a desired output voltage or in parallel to provide a desired current capability (amperes) of the solar panel or the PV system. Solar panels also use metal frames consisting of racking components, brackets, reflector shapes, and troughs to better support the panel structure.[2] History[edit]
What Makes You Happy? Think about it. Close your eyes for a few seconds and think about it again. If you have got an answer, are you sure about that answer? If you have not got an answer, are you still searching for one? Actually, this is a trick question forcing you to come up with a reason to be happy. if you fall for that trap and choose to answer the question, immediately you surrendered yourself to conditional happiness. What if you chose the default to be “happy?” What if you really need a “good” reason to make you unhappy? That would change the game completely.

I won't cover every last line of code, every intermediate step, or every detail of hardware; that would take a book and would be obsolete by the time you read it. The goal is to show you what kinds of concerns and pitfalls you'll face should you want to do this. For this piece, we build the access point to operate as a bridge; simply forwarding packets between the wireless network and a local ethernet. Why bother? Maybe I should start with "Why not to bother." The first is flexibility and customizability. The other -- and perhaps more compelling -- reason is that it's fun, and it's a good way to learn about the issues you may face running an embedded Linux system. Back to top Requirements The computer I used for this project is a Soekris net4521 embedded system. To follow the whole thing, you'll also need another Linux box, to format and configure the flash card. Project plan Initial setup
