aria2 is a lightweight multi-protocol & multi-source command-line download utility. It supports HTTP/HTTPS, FTP, BitTorrent and Metalink. aria2 can be manipulated via built-in JSON-RPC and XML-RPC interfaces.
- Multi-Connection Download. aria2 can download a file from multiple sources/protocols and tries to utilize your maximum download bandwidth. Really speeds up your download experience.
- Lightweight. aria2 doesn’t require much memory and CPU time. When disk cache is off, the physical memory usage is typically 4MiB (normal HTTP/FTP downloads) to 9MiB (BitTorrent downloads). CPU usage in BitTorrent with download speed of 2.8MiB/sec is around 6%.
- Fully Featured BitTorrent Client. All features you want in BitTorrent client are available: DHT, PEX, Encryption, Magnet URI, Web-Seeding, Selective Downloads, Local Peer Discovery and UDP tracker.
- Metalink Enabled. aria2 supports The Metalink Download Description Format (aka Metalink v4), Metalink version 3 and Metalink/HTTP. Metalink offers the file verification, HTTP/FTP/BitTorrent integration and the various configurations for language, location, OS, etc.
- Remote Control. aria2 supports RPC interface to control the aria2 process. The supported interfaces are JSON-RPC (over HTTP and WebSocket) and XML-RPC.
A secure socks5 proxy, designed to protect your Internet traffic.
- Super Fast Bleeding edge techniques with Asynchronous I/O and Event-driven programming.
- Flexible Encryption All traffic encrypted with industry level encryption algorithms. Flexible to support custom algorithms.
- Mobile Ready Optimized for mobile device and wireless network, without keep-alive connections.
- Cross Platform Avaliable on multiple platforms, including PC, MAC, Mobile (Android and iOS) and Routers (OpenWRT).
- Open Source Open source community with multiple implementations in python, node.js, golang, C#, and pure C.
- Easy Deployment Easy deployment with pip, npm, aur, freshports and many other package manager systems.
With ownCloud you can sync & share your files, calendar, contacts and more. Access your data from all your devices, on an open platform you can extend and modify.
- Protect ownCloud gives you control over your data. You decide what is shared with who and for how long.
- Access Access your data from your web browser, Android or iOS devices and your laptop and desktop.
- Extend Add apps, external storage, or your own code! Join the friendly open source community and get started!
Set up a LAMP stack on OpenWrt
- nginx nginx [engine x] is an HTTP and reverse proxy server, as well as a mail proxy server, written by Igor Sysoev. For a long time, it has been running on many heavily loaded Russian sites including Yandex, Mail.Ru, VK, and Rambler.
- php PHP is a popular general-purpose scripting language that is especially suited to web development.
- mysql MySQL is a database system used on the web MySQL is a database system that runs on a server MySQL is ideal for both small and large applications MySQL is very fast, reliable, and easy to use
EVERYONE DESERVES A FREE PPTP VPN ACCESS TO ANYWHERE
- Protocol description nA PPTP tunnel is instantiated by communication to the peer on TCP port 1723. This TCP connection is then used to initiate and manage a second GRE tunnel to the same peer.
- Implementations PPTP was the first VPN protocol that was supported by Microsoft Dial-up Networking. All releases of Microsoft Windows since Windows 95 OSR2 are bundled with a PPTP client, although they are limited to only 2 concurrent outbound connections. Microsoft Windows Mobile 2003 and higher also support the PPTP protocol. The Routing and Remote Access Service for Microsoft Windows contains a PPTP server. The Microsoft implementation uses single DES in the MS-CHAP authentication protocol which many find unsuitable for data protection needs.
- Security PPTP has been the subject of many security analyses and serious security vulnerabilities have been found in the protocol. The known vulnerabilities relate to the underlying PPP authentication protocols used, the design of the MPPE protocol as well as the integration between MPPE and PPP authentication for session key establishment.
OpenWRT using AP+WDS mode to build a wireless relay
- AP1 (principal) configuration: 1.DHCP open; 2 wireless Mode select AP+WDS; 3 fixed channel
- AP2 (guest) configuration: 1 off DHCP; 2 two wireless Mode were selected for Client (WDS) and AP. The two router subnet cannot be the same (like I AP1 is set to 192.168.1.1, AP2 is set to 192.168.2.1 segment)
#Openwrt make && make luci
##Requirement to generate an installable OpenWrt firmware image file with a size of e.g. 8MB:
- Install OpenWrt Buildroot and its prerequisites on your OS.
- ca. 3-4 GB of available hard disk space
- environment variables:
- SED should not be set. If it is, run
unset SEDbefore compiling. - GREP_OPTIONS should not have –initial-tab or other options affecting its output
- Add /staging_dir/host/bin and /staging_dir/toolchain--<gcc_ver>-<libc_ver>/bin in front of your PATH variable in ~/.bashrc. The staging directory is created shortly after starting the build and the toolchain directory is created when the toolchain build begins. The build spawns multiple shells, some of which expect the toolchain binaries to be present in the PATH.
##Installation before you install Openwrt , you should be root
su root
then install need package:
yum install libncurses5-dev zlib1g-dev bison flex unzip autoconf gawk make gettext gettext texinfo sharutils gcc binutils ncurses-term patch bzip2 libbz2-dev libz-dev asciidoc subversion sphinxsearch libtool git git-core curl ncurses-devel zlib-devel gcc-c++ openssl-devel
you can add user openwrt and set password
adduser openwrt
passwd openwrt
su openwrt
get from svn git（ The source is modified with the openwrt official stability version ）
cd ~
git clone https://github.com/crysisx/GDG-DevFest-2014-OpenWrt.git
cd GDG-DevFest-2014-OpenWrt
Updating Feeds
./scripts/feeds update -a
./scripts/feeds install -a
The OpenWrt Buildroot configuration interface handles the selection of the target platform, packages to be compiled, packages to be included in the firmware file, some kernel options, choose what you need package and luci
###then Defconfig
make defconfig
###then Defconfig
make prereq
###then Defconfig
make menuconfig
###Building Images
make V=99
###Locating Images
After a successful build, the freshly built image(s) can be found in the newly created <buildroot_dir>/bin directory. The compiled files are additionally classified by the target platform, so e.g. a firmware built for an ar71xx device will be located in <buildroot_dir>/bin/ar71xx directory.
##Cleaning Up
###Clean
make Dirclean
deletes contents of the directories /bin and /build_dir. make clean does not remove the toolchain, it also avoids cleaning architectures/targets other than the one you have selected in your .config ###Dirclean
make dirclean
deletes contents of the directories /bin and /build_dir and additionally /staging_dir and /toolchain (=the cross-compile tools) and /logs. 'Dirclean' is your basic "Full clean" operation. ###Distclean
make distclean
nukes everything you have compiled or configured and also deletes all downloaded feeds contents and package sources.
