Are you tired of clicking on some link from a web portal, only to find that the website is temporarily off-line because thousands or millions of other users are also trying to access it? Does your network have a really low-bandwidth connection, such that everyone, even accessing the same web pages, suffers from slow downloads? Have you ever run a website, only to find that suddenly you get hit with a spike of thousands of requests, overloading your server and possibly causing high monthly bills? If so, CoralCDN might be your free solution for these problems!

Guess what? Almost all capacity changes are foreseeable. If you had done proper capacity planning, you would have had two key advantages:

* You would have added the capacity before it was needed, guaranteeing that the proper capacity is always in place.

* You would have discovered any operational issues with Amazon S3 before they impacted your operations (and thus allow you to take alternative steps to deal with the situation).

In our benchmarks we were only able to push 35 MB/s on small instances. So the actual requests per seconds were dependent on the object size we were pushing. The limit was always ~35 MB/s. Our typical HTML pages were around 50 to 70 KB, so we couldn’t reach the desired requests per second as our instance was at its bandwidth limit.

Usually when one instance hits its resource limits you load balance multiple ones. HAProxy is a fine example for a very robust TCP/HTTP load balancer. The problem is though, that it will not increase your bandwidth as all your traffic has to go through this one HAProxy instance. So even when you load balance multiple instances, each one is capable of pushing ~35 MB/s (—> ~350 MB/s with 10 small instances), the bottleneck will still be at ~35 MB/s (aka the load balancer).

Port Knocking and Single Packet Authorization are new techniques in the network security field that provide a mechanism to have all ports of a server closed and open them to clients that issue specific sequences of connection attempts or specially crafted packets that contain the appropriate authentication credentials. Aldaba is a command-line tool for Linux systems that implements a PK and SPA client and server that provides secure stealthy authentication and remote firewall rules manipulation using TCP/IP covert channels.

This document is an HOWTO on installing a Apache based WebDAV server with LDAP for authentication and SSL encryption.

The hack is not a complete break; it only results in the ability to read and falsify particular short data packets, but cannot retrieve a WPA encryption key. Still, the rapid development of WPA hacks suggests that those paranoid about security ensure that their WiFi networks are using WPA2 with AES encryption rather than WPA with TKIP.

This specification defines an API that enables Web pages to use the Web Sockets protocol for two-way communication with a remote host.
