How to on neural network

Hey! Socket programming got you down? Is this stuff just a little too difficult to figure out from the man pages? You want to do cool Internet programming, but you don't have time to wade through a gob of structs trying to figure out if you have to call bind() before you connect(), etc., etc.

Well, guess what! I've already done this nasty business, and I'm dying to share the information with everyone! You've come to the right place. This document should give the average competent C programmer the edge s/he needs to get a grip on this networking noise.

And check it out: I've finally caught up with the future (just in the nick of time, too!) and have updated the Guide for IPv6! Enjoy!

Software developers using Windows have a fantastic process explorer, made by Mark Russinovich. Linux lacks such a process explorer tool. This projects aims (in the end) to be an equivalent process explorer for Linux.

Goal is to have the same functionality of the Windows process explorer under linux, or less if linux limits us.

netem provides Network Emulation functionality for testing protocols by emulating the properties of wide area networks. The current version emulates variable delay, loss, duplication and re-ordering.

which can be useful for connection with lots of jitter

Mosh(mobile shell) is Remote terminal application that allows roaming, supports intermittent connectivity, and provides intelligent local echo and line editing of user keystrokes.

Mosh is a replacement for SSH. It's more robust and responsive, especially over Wi-Fi, cellular, and long-distance links.

Mosh is free software, available for GNU/Linux, FreeBSD, Solaris, Mac OS X, and Android.

Specifically, the deprecated Linux networking commands in question are: arp, ifconfig, iptunnel, iwconfig, nameif, netstat, and route. These programs (except iwconfig) are included in the net-tools package that has been unmaintained for years. The functionality provided by several of these utilities has been reproduced and improved in the new iproute2 suite, primarily by using its new ip command. The iproute2 software code is available from Kernel.org. Iproute2 documentation is available from the Linux Foundation and PolicyRouting.org.

ntopng is the next generation version of the original ntop, a network traffic probe that shows the network usage, similar to what the popular top Unix command does. ntop is based on libpcap and it has been written in a portable way in order to virtually run on every Unix platform, MacOSX and on Win32 as well.

Soit 2 Freebox ADSL plafonnant joyeusement autour de 4Mb/s, et partageant le même réseau local.
Comment agréger les box pour obtenir 8Mb/s ? Avec “OpenVPN Bonding” bien sur… et quelques autres trucs.

Random cours stuff (mainly network)

OpenVas est le remplaçant libre de Nessus, devenu non-libre.

Nessus et OpenVas sont des scanners réseau permettant de relever des failles de sécurité sur tous types de systèmes (Unix, Linux, Windows, Cisco, HP, …). OpenVas s’installe sur les principaux systèmes Linux, ici, je montre une installation sur Debian Wheezy.

Une attaque réseau qui permet d'écouter le trafic d'une autre machine qui est connectée sur le même réseau que nous.

OpenVPN is SSL/TLS VPN solution. It is able to traverse NAT connections and firewalls. This page explain briefly how to configure a VPN with OpenVPN, from both server side and client side.

Block lot's of bad stuff (know malicious website, us agencies, etc ...) using ip list.

"MultiPath TCP (MPTCP) is an effort towards enabling the simultaneous use of several IP-addresses/interfaces by a modification of TCP that presents a regular TCP interface to applications, while in fact spreading data across several subflows. Benefits of this include better resource utilization, better throughput and smoother reaction to failures."

MPTCP est une extension du protocole TCP qui permet de gérer les connexions de manière agnostique. C'est spécialement utile pour la mobilité, quand on a par exemple 2 connexions actives wifi/3G.

Apple l'a déja implémenté sur iOS7 pour la gestion du traffic généré par Siri. A mon avis c'est "the next big thing" comme ils disent aux states...
