flv streaming with lighttpd
by camel
& 2 others
(via)
1.4.11 got a new module for streaming Flash movie files called mod_flv_streaming. This module allows you to seek in FLV files using the high performance infrastructure of lighttpd.
The idea is simple and explained and implemented on ‘Streaming’ flv video via PHP, take two at http://www.flashcomguru.com/
But instead of streaming the file through PHP we do it in the webserver. The module expects a request for the URL which matches flv-streaming.extensions and can handle a ’?start=’ as part of the request.
The information to pass into the ‘start’ parameter is extractly by the flash-player from the meta-data of the flv-files. The meta-data can be setup with flvtool2
Now I leave it to you to combine this with mod_secdownload to create a flv-streaming server for free with deep/hot linking protected movies.
server.modules = (
...,
"mod_secdownload", ## optional
"mod_flv_streaming",
...
)
flv-streaming.extensions = ( ".flv" )
Take the flash-player from flashcomguru and adjust the URL in the player and try yourself.
How To Set Up A Load-Balanced MySQL Cluster With MySQL 5.1 | HowtoForge - Linux Howtos and Tutorials
by camel
This tutorial is based on Falko Timme's tutorial for MySQL Cluster 5.0. It shows how to configure a MySQL 5.1 cluster with five nodes: 1 x management, 2 x storage nodes and 2 x balancer nodes. This cluster is load-balanced by an Ultra Monkey package which provides heartbeat (for checking if the other node is still alive) and ldirectord (to split up the requests to the nodes of the MySQL cluster).
In this document I use Debian Etch 4.0 for all nodes. Therefore the setup might differ a bit for other distributions. The two data nodes were x64 to use all of the 8GB RAM. Servers were compiled from source so you should be able to make it running on any platform. The MySQL version I use in this setup is 5.1.24-rc. It's a release candidate, but I wanted to use 5.1 to take advantage of Memory-Disk Based tables.
Beginning with MySQL 5.1.6, it is possible to store the non-indexed columns of NDB tables on disk, rather than in RAM as with previous versions of MySQL Cluster.

How To Set Up A Debian Linux WebCam Server Using a USB Web Cam
by camel
& 1 other
First and foremost, be prepared to have some patience when trying to get a USB cam to work under Linux. In trying to get mine to work, I searched many a newsgroup thread only to find there was only one message in the thread, the original question stating the problem. i.e. no one had an answer for the person who posted the question so you may be on your own trying to get your cam to work. Often times the same camera model will use different drivers for different sub-models (ex: not all QuickCam Express sub-models use the same driver). However, my trials and tribulations were a good learning experience and I'll share what I learned here to hopefully make your setup easier.
Setting Up A Modular Subversion Repository For PHP-Driven Websites | HowtoForge - Linux Howtos and Tutorials
by camel
Sharing code between projects is still not a trivial matter with subversion. Especially if you are familiar with SourceSafe, you will find that subversion makes it hard to share code. Subversion seems to be really great in creating a version mess and good in solving one, but the reason I need source code control is to prevent such a mess. This is where subversion can be greatly improved, but it is not impossible. This howto will demonstrate a directory setup that takes the subversion sharing mechanism into account, as well as other issues that repositories bring.

Lighttpd Webserver setup with php5 and Mysql support -- Ubuntu Geek
by camel
Security, speed, compliance, and flexibility — all of these describe lighttpd (pron. lighty) which is rapidly redefining efficiency of a webserver; as it is designed and optimized for high performance environments. With a small memory footprint compared to other web-servers, effective management of the cpu-load, and advanced feature set (FastCGI, SCGI, Auth, Output-Compression, URL-Rewriting and many more) lighttpd is the perfect solution for every server that is suffering load problems. And best of all it’s Open Source licensed under the revised BSD license.
skorpionweb.org: Running QMail SMTP on a 2nd port
by camel
Due to the increase in the number of ISP's blocking port 25 for third party mailservers I decided to setup my mailserver to answer SMTP request on multiple ports. While this can be accomplished in many ways, such as port forwarding or multiple instances of qmail-smtpd, my situation required setting up a second instance or qmail-smtpd.
