In this installment of the iC2I series, Don walks you through dumping a Virtual Server to the command line. This is the first in a series of articles that will result in a tree view of the BIG-IP.

Our extended Microsoft Partner Team spent last week in Las Vegas for the Microsoft Management Summit. While a few members of our team attended the sessions & trainings, the rest of us manned the F5 booth. We had a phenomenal turnout, and it was great to meet those of you who stopped by! There were several highlights from the show. We brought several members from our ControlPoint team, who gave the first public demos of the upcoming product. For those of you who aren't aware of ControlPoint yet, it is our yet-to-be-released F5 monitoring solution that is built upon System Center Operations Manager 2007. The feedback from the demo was extremely positive, with most people ecstatic about the OpsMan platform that we have chosen to go with. Dan & Jennifer giving a ControlPoint demo Look Calvin, I'm working!!! Heavy traffic again this year at the booth We also introduced our Microsoft centered Virtualization Strategy, which focuses on dynamically provisioning services in the network. We have been working with our friends at HP to build a demo of the solution, ...

I'm working on something else that's sort of related to this subject and noticed that rpaan polished the PHP code for this article on using PHP and iControl. It's nice. Great stuff, rpaan, and THANKS! Imbibing: Water

LTM, Routing, and Multiple Gateways Today Deb & Colin discuss the steps required to configure LTM to "source route" traffic (preferring a specific external next-hop gateway for connections originating on different internal VLANs) and to ensure return traffic uses the "correct" gateway when more than one is available. The post contains all the configuration details and a b-e-a-u-tiful ASCII diagram from one of our favorite F5 Consultants, Mr. Denny Payne: See also: Source routing.

This is an interesting article from Network World about how CIOs in Australia and New Zealand perceive security as being easier than reducing costs. The IDC Annual Forecast for Management report surveyed 363 IT executives from Australia (254 respondents) and New Zealand (109 respondents) across industries including finance, distribution, leisure and the public sector. CIO Challenges Application layer threats 36% Spyware 16% Information Security Bottom of the stack The CIOs top priority for the next 12 months was reducing costs and addressing a lack of resources. Okay, here's a RADICAL idea. Let's reduce costs and address a lack of resources while dealing with application layer threats - all at the same time. Not kidding. A web application firewall (WAF) can address application layer threats. Because the WAF is performing an ever-vigilant watch over the applications, developers and security professionals can concentrate on other things - freeing up resources and reducing costs. What's also interesting is that if the WAF is paired with an intelligent application delivery controller, capabl...

Tech Republic blogger Toni Bowers discusses five high-tech skills that are waning as far as ability to command high salaries according to a recent Network World article. At the top of the list? HTML. Denise Dubie writes in the Network World article: As companies embrace Web 2.0 technologies such AJAX, demand for skills in HTML programming are taking a back seat. According to Foote Partners, pay for skills in technologies such as Ajax and XML increased by 12.5% in the last six months of 2007, while IT managers say they don’t see a demand for technology predecessors such as HTML. "I’m not seeing requirements for general Web 1.0 skills -- HTML programming skills," says Debbie Joy, lead solution architect for CSC in Phoenix. Dude, wait? What? I hate to be the one to break this news, but HTML is still very necessary in a Web 2.0 world. All the AJAX in the world isn't going to be very useful to clients if it can't be displayed and guess how that happens? Yes, good old HTML. While it's true that in a Web 2.0 world the HTML is predominantly programmatically generated, but it's still HTML whether it's spit out by a server-side script/application like ASP or PHP or patched together using JavaScript and XML. Someone still has to un...

In the Tech Tips, Deb is covering iRule Interference; Don is Virtually Dumping and iRule'ing virtuals; Colin is Encrypting Arrays, and Joe is Automating Licenses.
Colin is blogging about free MP3s and LoL'ing at his 20 lines; Don is Deep in the Hoopla and thinking about What a Wonderful World it would be; Joe is Teeing his Tickles, U'ing his URLs, and Vee-ing his VIPs; and Jeff is pondering Golf over Bowling balls.
In the forums we've got Pool Members status of Wideips, Browser type decisions, Single Virtual IP for Exchange, and Outbound SNAT matching.
DNS is ruling the CodeShare this week.
Deb and Colin are working on a new Post of the Week covering LTM Routing and Multiple Gateways;
the Daily News covered a whole bunch of stuff that caused an internal debate and Don offers up a new gadget.
Jeff finishes things off with a note to the Peanut Gallery.

What could you do with your code in 20 Lines or Less? That's the question I ask every week, and every week I go looking to find cool new examples that show just how flexible and powerful iRules can be without getting complicated. For the real 20LoL this week, we go back to pilfer the wonderful collection of raw brainpower that is the DevCentral forums. Digging through just a few forum posts gave me a couple of tasty little iRules to share with the class for this week. Not only is this stuff cool, easy to implement, and done in less than 21 lines of code, it's done by real world users that dig this stuff so much they share it with the rest of us. Now that's rockin'. So without further gilding the lily and with no more adieu, I give you this week's 20 Lines or Less, brought to you by the forums, where good brains come to get better, and kittahs everywhere enjoy their cheezeburgerz. HTTP to HTTPS redirects - in the Location header http://devcentral.f5.com/Default.aspx?tabid=53&forumid=5&postid=23172&view=topic
Ever have a need to ensure that all the redirects being sent by your servers were secure links? Well, if you've ever tried to offload SSL to your LTM with a system that has hard-coded links in it, you just might...

The letter for the day in the Networking ABC's is the letter "V". Vary headers, verification, and VLAN's find a home with the letter V, but I opted for a word that enables scaling of websites by virtualizing the resources. Todays word is the word "VIP" "V" is for VIP VIP Pronounced: vip VIP, not be confused with V.I.P. or Very Important Person, stands for Virtual IP. A Virtual IP is a mechanism to allow for scalaing and maintenance no a physical resource by virtualizing the access to that device. A server is accessed by it's network address. By configuring a virtual address to an application (say www.f5.com), a company is able to install many physical servers behind the virtual address that provide access to the requested application while exposing it through a single network address. Even with the advances in computing power, active websites cannot be supported by a single computer and rely on some form of virtualization, also known as load balancing.

File virtualization and storage are gaining a lot of mindshare lately, probably because the longer a business runs the more data they have to store. And with compliance regulations, sometimes that means not only more data to store (like all your e-mail) but storing it for a very long time. And then there's building out large farms of servers to support high volume sites. File virtualization makes a lot of sense when you're trying to manage large numbers of servers, especially if they're essentially clones. And let's not ignore the other kinds of virtualization; if you're set on OS virtualization you're going to need to store - and potentially share - those images somewhere, and what better way to accomplish that then by using file virtualization? What? You're not really up on file virtualization and its benefits? Then have I got some good news for you. F5 Acopia Data Solutions will be hosting a free webinar on May 22 on file virtualization. Learn how it works, how to reap the benefits, and get a copy of File Virtualization For Dummies®, hot off the presses. You can find more information and details as well as register for the webinar here. Imbibing: Coffee Technorati Tags: MacVittie,F5,file virtualization,webinar,free,...
