Wow , excited, New year, I in 2016, I bought a card size board, Raspberry Pi, yesterday to the goods, the night began a toss-up tour① There is no wired network connection on the wireless network, in this need to thank one person, he provided the tutorial Duang-max? 1029086180, one of the great gods.② Preparation Tool (Hardware):⒈ Raspberry
Securi-Pi: Uses Raspberry Pi as a stepping stone for securityGuideLike many readers of LinuxJournal, I have also lived a very common "technology nomadic" life today, from one access point to another between networks, we are in different places in the real world, but we are always connected to the Internet and other networks that are commonly used.

But I haven't tested it yet behind a firewall like this.
