Want FAST Reverse WEB Accelerator?

info@ph-lwug.org (aeonmike) — Wed, 25 Jan 2012 22:41:33 PST

Varnish Cache is a web application accelerator also known as a caching HTTP reverse proxy. You install it in front of any server that speaks HTTP and configure it to cache the contents. Varnish Cache is really, really fast. It typically speeds up delivery with a factor of 300 - 1000x, depending on your architecture. A high level overview of what Varnish does can be seen in the video attached to this web page.

Performance

Varnish performs really, really well. It is usually bound by the speed of the network, effectivly turning performance into a non-issue. We've seen Varnish delivering 20 Gbps on regular off-the-shelf hardware.

Flexibility

One of the key features of Varnish Cache, in addition to it's performance, is the flexibility of it's configuration language, VCL. VCL enables you to write policies on how incoming requests should be handled. In such a policy you can decide what content you want to serve, from where you want to get the content and how the request or response should be altered. You can read more about this in our tutorial.

Licence and origin

Varnish is free software licensed under a two-clause BSD licence, also known as the FreeBSD licence. The project was initiated in 2005. Varnish Cache 1.0 was released in september 2006.

The name "Varnish"

The name Varnish comes from when the instigator of Varnish spent a long time staring at an art-poster with the word “Vernisage” and ended up checking it in a dictionary, which gives the following three meanings of the word:

r.v. var·nished, var·nish·ing, var·nish·es

To cover with varnish.
To give a smooth and glossy finish to.
To give a deceptively attractive appearance to; gloss over.

Squid as a bridged transparent proxy in Centos5

info@ph-lwug.org (lordfrancis3) — Sat, 21 Jan 2012 06:22:55 PST

Squid is free open source application used as a proxy server and web cache daemon originally designed to run on Unix-like systems, it also runs well on Windows-based systems. Squid has a wide variety of uses. Although primarily used for HTTP and FTP, Squid includes limited support for several other protocols including TLS, SSL, Internet Gopher and HTTPS.

To install squid run the command

_{#yum install squid}

After the installation is finish, edit the squid configuration file using a text editor

_{#vi /etc/squid/squid.conf}

Modify or add following squid directives

_{http_port 3128 transparent

always_direct allow all}

Create an ACL (Access Control List) which contains ip address or pool of ip address.

_{acl lan src 192.168.1.1 192.168.2.0/24}

Ip address can be separated by spaces. Squid allow access to LAN and localhost ACL

_{http_access allow localhost

http_access allow lan}

When you are done with your squid, the next step is to configure your Centos as a bridge. Remember that there are number of approach to do your transparent proxy depending on your situation or liking, it is either make your Linux box as a router, do a NAT, re-route traffic coming form port 80 to your proxy server or in

vSphere 4.0 vs XenServer 5.5 vs Hyper-V R2

Benchmarks: vSphere 4.0 vs XenServer 5.5 vs Hyper-V R2 for Terminal Services and VDI workloads

Posted by virtualization.info Staff | Tuesday, February 16th, 2010 |

Exactly one year ago two well-known virtualization experts Ruben Spruijt (Solution Architect and CTO at PQR) and Jeroen van de Kamp (Enterprise Architect and CTO at Login Consultants) releasedan independent, non-sponsored performance analysiscomparing ESX 3.5, XenServer 5.0 and Hyper-V 2008.

The benchmark, specifically designed to measure desktop virtualization workloads (served by Terminal Services and VDI platforms), was so valid that Citrix decided to embrace the Virtual Reality Check methodology to measure XenDesktop 4 performance.

Twelve months later the two are back with a new comparison. This time they put side by side Citrix XenServer 5.5, Microsoft Windows Server 2008 R2 Hyper-V and VMware vSphere 4.0 Update 1, comparing them against their new workload simulator Virtual Session Indexer (VSI) 2.0.

The most interesting thing is that all tests were performed on HP hardware equipped with the new Intel Xeon 5500 Series CPUs (codename Nehalem), and compared to Virtual Reality Check 1.0 results obtained on previous generation processors.
Performance are almost doubled with both XenServer and vSphere, and with Hyper-V R2, performance are up 154%.

Once again, if you are involved in a desktop virtualization project this performance analysis is a mandatory reading.

Introduction

Why spend a fortune on Windows server software when you can get more for so much less?!

SME Server is an Open Source Linux Server distribution and provides a flexible, worry-free, secure, network and communications server solution you won't outgrow. It is designed to be:

Simple to setup and use: Installation and basic configuration takes less than 20 minutes, and every configuration option can be set via a web-based interface.
Secure and stable to operate: SME Server only includes what is necessary, which translates into the entire ISO being around 500MB. Stability comes from using proven, supported rpm packages and from an update system that notifies you with available updates.
Cross-platform and extendible to meet future needs: SME Server already has everything necessary to provide the core services most people need to network Linux, Macintosh, and Windows systems.
And it's completely free!
Download the ISO from http://wiki.contribs.org/SME_Server:Download

Exceptionally reliable and easy to use, SME Server can be installed and configured in less than 20 minutes - yet it's powered by a secure and open Linux platform that's fully upgradeable and customizable. Simply install it on any standard PC and in minutes you'll have a robust Linux-based LAMP server capable of fully replacing those expensive Windows server licenses and providing a full range of services - including e-mail, firewall, file and print-sharing, web hosting, remote access and more.

SME Server integrates easily with Windows, Macintosh, and Unix/Linux clients, and within a Windows network environment. It's as simple to use as a server appliance, but unlike a "sealed-box" appliance the entire system is modular and extensible, so it can be tailored to the needs of individual businesses.

Greetings from the Software Freedom Network!

We are cordially inviting you to participate in the celebration of Software Freedom Day (SFD) 2011 in the Philippines on September 17, 8:00am – 5:00pm at the University of Santo Tomas (UST). SFD is a yearly celebration of software freedom that aims to educate the public about the value and importance of software
freedom.

Free and open source software (FOSS) are free, high-quality alternatives to proprietary software ranging from your operating system to applications you would use at home, in business, education and other social purposes. The affordability and viablity of FOSS tools have important economic and social impacts especially in third world countries like the Philippines.

The FOSS community intends to share its role in advancing the Filipino people's right to freedom of information in this year's SFD celebration, with the theme "FOSS: Enabling Freedom of Information". The event will have parallel plenary sessions on topics and issues regarding FOSS in the morning, followed by
breakout sessions in the afternoon featuring introductory trainings on FOSS applications and concepts. Hundreds of teams worldwide celebrated SFD in 2010. Over 700 celebrants trooping to the University of the Phililppines Diliman Campus and around 1,500 pre-event celebrants in Lipa City College. And we are expecting more participants this year! Your full participation in the event would definitely contribute to this year's success.

Welcome to CentOS 6.0

info@ph-lwug.org (lordfrancis3) — Wed, 13 Jul 2011 17:20:11 PDT

Welcome to the CentOS 6.0 release. CentOS is an Enterprise-class Linux Distribution derived from sources freely provided to the public by our Upstream OS Provider (UOP)¹.

CentOS conforms fully with the upstream vendor's redistribution policy and aims to be 100% binary compatible. (CentOS mainly changes packages to remove upstream vendor branding and artwork.)

CentOS 6.0 represents many changes from previous releases.

CentOS 6.0 has been completely rebuilt using a newer build system and library checks to confirm upstream binary compatibility.

We have decided not to follow the UOP's usage of Installation Codes. All 'channels' are available to the System Administrator at time of installation.

Please read through the other sections before trying an install or reporting an issue.
