Come one, come all to our third edition of the iRule. Do You? Contest. For those that don't know, an iRule is F5's embedded packet scripting language allowing you to gain full control over how your applications flow across the network. There are hundreds of iRules in our iRule CodeShare and thousands of them running out in the wild. It's time for you iRule geeks out there to show us, and our community, your stuff. Whether you are an avid developer or just someone who wants to dabble in new technologies, this contest is for you. The rules...
Every now and then we get some interesting email addressed to us here on the DevCentral team. Most of the time they are not blog worthy, but yesterday one came in that I thought I needed to share. Instead of trying to provide some witty commentary, I’m just going pass along what was in the email and leave it to you to comment on. To: DevCentral From: Ian Subject: My First iRule ...
Today, I decided to take a break away from Twitter and catch up on some of the 1000's of blog posts I'm behind on reading. So, I launched up Google Reader and came across Scott Hanselman's post on "IE6 Warning - Stop Living In The Past - Get off of IE6". In his post, he talks about a movement to get folks off the ancient IE6 and onto a more recent, more secure browser.
In Scott's post, he showed off some of the stats for his blog revealing that close to 20% of the viewers of his site were using...
This just came across the wire: The UK based website ITPRO just published the first public review of F5's VIPRION On-Demand Application Delivery Controller. Let's see how it fared: Rating: 5 out of 6 stars Price: £83000 "Targeting enterprises and service providers, the Viprion offers a range of features suited to those looking for levels of resilience, scalability and performance that standard appliance based solutions can’t deliver." "A unique feature of the Viprion is its ability to present a single virtual server with massive resources behind it as it can use all blades. As new blades are added they...
Hot off the presses! I just received an email from Beth, our Director of World Wide Customer Education, that starting now registration is open for a brand spanking new "Configuring BIG-IP V9.x With iRules" course offered by F5 Global Training - WOOHOO! This three-day course gives networking professionals an understanding of how to configure a BIG-IP v9 system with iRules. The course builds on the foundation of the BIG-IP Local Traffic Manager (LTM) Essentials course, demonstrating how to logically plan and write iRules to help monitor and manage common tasks involved with processing traffic on the BIG-IP. Course...
I found out about this at our partner conference earlier this week and it looks like Symphonic's TrueView ADC Edition has made it's way out into the wild. From the press sheet: Symphoniq, in conjunction with F5, has created a unique monitoring solution to leverage your existing Application Deliver Controller (ADC) infrastructure to give you detailed, actionable insight into how the infrastructure is running, from your end user's perspective. TrueView, ADC Edition takes advantage of Symphoniq's TrueView technology to measure real end-user response times, and leverages F5's iRules and iControl technologies to seamlessly integrate with your infrastructure to...
Here's another post on Japanese Marketing, F5 Style. I've talked about iRules, TMOS, and FirePass and for today I've got our very own BIG-IP. As I mentioned in my previous posts, since I don't speak Japanese, the only way I can interpret this marketing sheet is by the graphics on it. So, again, I'll give you my view on what the message is: The guy in this photo is not really a guy at all, he's a puppet since there is no bottom half to his body. The left picture shows him with a blue forehead...
While Jeff and I were in Tokyo a few weeks back, we spent some time in F5's office and what immediately caught my eye was the lack of human models in their marketing literature. As you can see in the above sheet, artists drawings are used instead of photos of real people. In fact, this isn't just a tech thing because the same can be seen while riding on the subway. I don't know this for a fact, but I would wager a couple of yen on the fact there is one artist in Japan that does...
The letter for today in the Networking ABC's is the letter "I". Words that come to mind starting with "I" are ICMP, IPSec, Interface, and the Internet. But since I get to pick the words, I picked my favorite "I" networking word: iRule. "I" is for iRule iRule Prounounced: Ahy-rool An iRule is a powerful and flexible feature of BIG-IP devices based on F5's exclusive TMOS architecture. iRules provide you with unprecedented control to directly manipulate and manage any IP application traffic. iRules utilizes an easy to learn scripting syntax and enables you to customize how you...
While some folks here at DevCentral like to think that they are all knowing with regards to folks in our community, the facts are that we only get a small glimpse into what challenges you face in your day to day lives while keeping your network and applications working like a well oiled machine. A while back I posted about becoming an iRule Ninja. I'm assuming everyone has read that post and taken the challenge to heart and now it's your opportunity to share with the DevCentral team how you've been kicking butt with the programming support with your...
Your first question after seeing the title of this post is probably something like: What the heck does iRules have to do with Bill Gates? I'll get to that... First, take a look at the map overlay of the users of DevCentral that I took a while back. I picked a day at random and pulled this from our Google Analytics account. For those who are running a website and are not doing analytic reporting on your site, I'd highly recommend you hop on over to Google Analytics and setup an account. It's free and fairly simple to...
I've been thinking about this for a while now, and am working on my pitch to F5 management, but I thought I'd float it past you all out in DevCentral land. I've been thinking about how we can move our products beyond the typical enterprise/government/finance/etc customer base and into the hands of "Joe Consumer". That got me to thinking about game systems: In my accounts, most households have at least one device capable of gaming. I'm not a big gamer by any means, but in my household, I do have a good set of gaming platforms that either...
This was just posted on our forums and I thought I'd pass it along. For those of you "I CAN HAS CHEEZBURGER" fans out there... For those who aren't "in the know" about LOLCats, check out the wikipedia article on them. If "ur" ever having odd behavior with "ur" iRulz, it may very well be this LOLCat who's messing with "ur" configuration. Hat tip to user wschultz for passing it along. I'll ditto his comments: "So go ahead and fess up, who was it?". I wish I could take credit but it wasn't me... -Joe Technorati Tags: Pruitt, F5,...
Jeff, Colin and I just finished up a set of training sessions to our new sales and SE folks about all the goodness that is DevCentral, iRules, and iControl. We had an hour and a half and the "plan" was 30 minutes DevCentral (Jeff), 30 minutes iRules (Colin) and 30 minutes iControl (me). Lesson learned: Jeff goes last from now on! Jeff rounded up his talk a little over the one hour mark, Colin sped his up to 20 minutes, which left me with 6 minutes to cover the iRule Editor and iControl. Luckily the folks opted to...
When looking at securing up your web application, there are a set of fairly standard attack patterns that application firewalls make use of to protect against those bad guys out there who are trying exploit your website. A good reference for web application attacks is the Open Web Application Security Project (OWASP). In this series of blog posts, I'm going to highlight different attacks and how they can be defended against by using iRules. In the first installment of this series I will show how to only allow valid HTTP requests to your application server. The most common HTTP versions out...
After many hours of hard work by the newest member of our team, The F5 DevCentral Advanced Design and Config Wiki went live this morning! To quote the site:
F5 products make it possible for you to build and manage very complex networks addressing an endless variety of application delivery and business requirements. This wiki is intended to support those complexities by providing samples of profiles, monitors, templates and common traffic management architectures, explaining the features required to implement them, and giving you tips on how to configure our products to match your application delivery requirements.
Enjoy everyone, and GREAT job Deb!
