What could you do with your code in 20 Lines or Less? That's the question I ask (almost) every week for the devcentral community, and every week I go looking to find cool new examples that show just how flexible and powerful iRules can be without getting in over your head. By a show of hands, who else here is surprised and/or excited that we finally made it to the 50th 20 Lines or Less? I'm a little of both, though more excited than anything. Years ago when I started the series I wasn't sure if anyone would...
In a shocking turn of events, the gracious sales readiness team invited me back to yet again present an iRules Challenge to the inbound FSEs during their multi-week grooming process here at F5 Seattle, lovingly known as "boot camp". It's a joy for me to be a part of these boot camps not only because I get to geek out about iRules and dream up challenges to get people more involved with DevCentral and iRules, two of my main squeezes in the tech world. But also because it's killer to see the talent rolling through, chat with some of them...
It would seem that, at least in this contest, everyone can indeed be a winner. I got the distinct pleasure to, once again, help contribute to the iRules delinquency education of our inbound FSE crew while they were here in Seattle for their boot camp. These folks are all technical, but very few have any iRules experience. Heck, most don't even have much scripting experience, so to lay down the gauntlet and say "Here, act like I'm a customer giving you these requirements, and go write me an iRule that'll make me happy." is a tall order. I'm very pleased...
A bit of twitter inspired silliness for you today:
Hello admins, how are you? Fantastic.
Does your network run like mine? No.
Can it work like mine? Yes
Should you use F5 to manage your network?
I don't know, do you like feeling secure?
Do you want an ADC that works like a combination of an App FireWall, WAN Accelerator and App Integrator that can block bad requests at the edge of the network that it's seamlessly accelerating while dealing with business intelligence all at the same time? Of course you do.

Happy Friday folks! I’m happy to report in that so far this morning I’ve been reading up on the latest version of LTM (10.2.1) that just got released, while rocking out to some (probably too loud) tunes, of course. The new version is a dot release, so it’s largely improvements and fixes, but there’s some very groovy stuff in there. Here are a couple good ones: Application templates This release includes one new application template and one upgraded application template. An application template corresponds to a particular application, such as email...
Phew! Having DC5 successfully out the door, I'm happy to resume my regularly scheduled programming. I'm back, bringing you my Top5 picks off of DevCentral every week. I'll help you sort through the content pouring across the (now new and improved!) site and offer you a few things that you should definitely check out. It's good to see that the content has still been chugging away even while the team was heads down working on the new site improvements. A big thanks to the awesome community and the extended DC team folks (Lori, Pete and co.) for keeping the lights...
What could you do with your code in 20 Lines or Less? That's the question I ask (almost) every week for the devcentral community, and every week I go looking to find cool new examples that show just how flexible and powerful iRules can be without getting in over your head. With the onslaught of work required to get DC5 up and running it’s been a while since I’ve offered some cool iRule goodness to the community from the community. There have been plenty of examples cruising through the forums, that’s for sure, I just haven’t had the time...
Time does fly when you're having fun, and trying to keep up with everything that's been going on with DevCentral is my kind of fun. I love watching what everyone is up to, from updates from the con to new folks blogging about their hippy proclivities, there's never a dull day in DC land. And all of this while we're hard at work on many things behind the scenes that aren't readily apparent just yet. Of course, I realize I may be slightly biased and not everyone is as apt to stay immersed as I am, hence the introduction of...

This week we’ve got a couple awesome new examples from two of the community all-stars, and one dusty old example from my archives. They’re all cool and useful, so take a peek and see what you think. If you want a problem solved or to submit an example, feel free,...
This week I bring to you a full house of content, docs over blogs. To say there have been more than a few pairs on DevCentral lately though would be an understatement. The rush of content could be likened to an avalanche but without the messy death and destruction bits to deal with. From interviews to tech tips to blog posts to original songs pertaining to cloud computing (no, I'm not joking, and no, the link isn't in here…go find it yourself), DevCentral never seems to sleep these days, which is just how we like it. In case you're overwhelmed...

I bring to you your weekly dose of short yet cool iRule goodness. Check out what these iRule fu masters have crammed into less than 21 lines of code. This week we’ve got hex translation of HTTP payloads, intelligent redirection including port handling, and some snat intelligence in just a...
The hits just keep on coming. Between the release of the LTM VE, some internal DC projects that are brewing, some new site stuff we're trying to polish up, and all that daily stuff that just keeps showing up out of nowhere, there has been no shortage of distractions. There has also, however, been no shortage of amazing content cruising through DevCentral, so this week's Top5 is packed full of it. You know there's a lot of cool stuff out there when I actually had to make a list of about 15 things I'd like to highlight and start whittling...
Many people in the networking world are aware of BIG-IP as a powerful load balancing and security device. Those that don’t dig deeper, however, are truly missing out on the incredible features just below the surface. Sure load balancing and security policies are interesting and important, but what truly makes BIG-IP stand out from the crowd, at least in my opinion, is the immense breadth of functionality available via the programmatic interfaces of the system, namely iRules, iControl and now tmsh. To me these are the most exciting, intriguing things happening in the market right now. Network side scripting, full...
What could you do with your code in 20 Lines or Less? That's the question I ask (almost) every week for the devcentral community, and every week I go looking to find cool new examples that show just how flexible and powerful iRules can be without getting in over your head. With the announcement of the BIG-IP LTM VE this week, the iRules world just got a little more interesting. Between the new commands and features that have come out in the past several months, and now the ability to build and test iRules from your laptop, without having...
What could you do with your code in 20 Lines or Less? That's the question I ask (almost) every week for the devcentral community, and every week I go looking to find cool new examples that show just how flexible and powerful iRules can be without getting in over your head. It’s been hectic here in DCland and finding time to write has been more difficult than normal, though that shouldn’t be a problem much longer. Fortunately for all of us this awesome community keeps kicking out the jams so I can rely on their hawesome knowledge to provide...

SIP topology hiding forward proxy http://devcentral.f5.com/wiki/default.aspx/iRules/SIP_topology_hiding_and_forward_proxy.html If you’re passing SIP traffic and want a way to mask the via & or from headers when passing traffic to the outside world, this might be just the rule you’ve been waiting for. It’s a cool look...
What could you do with your code in 20 Lines or Less? That's the question I ask (almost) every week for the devcentral community, and every week I go looking to find cool new examples that show just how flexible and powerful iRules can be without getting in over your head. This week not only are the examples cool and interesting, but one of them at least is extremely timely. You’ve no doubt heard about the client-initiated MITM attack for TLS that was recently disclosed. It’s front-page news around the web and for good reason. While research needs to...

Well we made it to 30 editions of the 20LoL. Soon we’ll break 100 iRule examples that are under 21 lines of code each. Pretty neat stuff, if you ask me. This week is the hoolio show, it seems. The guy is just a monster in the forums, what can...
If so, you had better hurry. You’re running out of time to submit your cool, unique, amazing or otherwise interesting iRules to this year’s iRule. Do You? contest. All you have to do is fill out one simple form and you’ll be entered to win some pretty hawesome prizes. If I weren’t disqualified for being an employee (and one of the judges) I would have submitted 10 entries by now for a chance at not only the sweet swag, but the glory of being the #1 iRuler on DevCentral. This contest is fun, for sure, but it’s also a...
Side-projects and behind the scenes activities abound as the DevCentral team works towards the next goal on our plans for world domination, carefully sketched on Jeff's whiteboard. I'm glad to say that the extended DC team has been helping, as always, to keep the content flowing though, and there's plenty to highlight this week. Take a look at this week's Top5: Closing in on the iRules Contest Deadline http://devcentral.f5.com/weblogs/jason/archive/2009/09/15/closing-in-on-the-irules-contest-deadline.aspx Jason points out a very important, timely fact. It's nearly the end of your window to submit killer iRules for great prizes! The iRules contest is...
The extended DevCentral team has been hard at work this week, as always, fulfilling your geek needs and then some. As such, this Friday's Top5 brings to you all types of DevCentral-y goodness. From text, to audio, to informative pictures, we've got it all this week. I've picked a few of the best, five to be exact, to share with you. Here they are: The Threat Behind the Firewall http://devcentral.f5.com/weblogs/psilva/archive/2009/09/09/the-threat-behind-the-firewall.aspx Pete Silva dives into drives this week in his piece on the dangers lurking behind seemingly benign usb drives. These undeniably handy devices can do...
What could you do with your code in 20 Lines or Less? That's the question I ask (almost) every week for the devcentral community, and every week I go looking to find cool new examples that show just how flexible and powerful iRules can be without getting in over your head. 29 editions later and still going strong. The 20LoL is a testament to just how many different things can be done with iRules in just a few lines of code. Just imagine the possibilities if this were the 30LoL. This week I’ve got three more examples,...
What could you do with your code in 20 Lines or Less? That's the question I ask (almost) every week for the devcentral community, and every week I go looking to find cool new examples that show just how flexible and powerful iRules can be without getting in over your head. Nearing the thirty mark with the 20LoL it occurs to me that I’m having a harder and harder time with something. No, it’s not finding interesting ideas to feature. The community has been absolutely stellar with that part. There are always plenty of iRules for me to grab...
I submit to you my second attempt at this week's Top5 after a vile BSoD swooped down and smote my first attempt into a pile of fiery ash. There were a couple announcements this week on DevCentral along with the expected awesome technical content. I'll try to touch on those as well as a couple other things that you should definitely check out in this week's DevCentral Top5: Announcing F5 Management Pack 1.4 for Microsoft System Center Operations Manager 2007 http://devcentral.f5.com/weblogs/sfisher/archive/2009/08/25/announcing-f5-management-pack-1.4-for-microsoft-system-center-operations.aspx The hard-working, quick-moving management pack team here at F5 brings you the newest version...
What could you do with your code in 20 Lines or Less? That's the question I ask (almost) every week for the devcentral community, and every week I go looking to find cool new examples that show just how flexible and powerful iRules can be without getting in over your head. Here are a few more cool iRules from the forums. This week I’ve included one of the simplest, shortest iRules to ever make the 20LoL. It just struck me as something quite useful that I’m willing to bet several people will look at and say “oh, that’s handy”...

This week we’ve got more cool iRules toys to show off. That’s not the impressive part, the impressive part is that only two of the three examples are from hoolio. I know, right? Joking aside, a huge thank you to hoolio for his astounding contributions to the community, and to...
What could you do with your code in 20 Lines or Less? That's the question I ask (almost) 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 in over your head. Digging through the forums this week turned up a couple more great examples of iRules that can fit in the palm of your hand. They’re so cute and cuddly at under 21 lines, but they pack a punch. It seems there’s more and more to keep up with in the forums these...
It's been busy! The DevCentral team and all of the awesome people in our extended family have been working away, putting out all kinds of great content for your perusal. Now that we're out of the hardcore v10 push and back into a more "normal" flow of content there has been a myriad of tasty morsels flowing through the DC channels. From a posh search experience to security secrets and new wrappers, we've had plenty to talk about. Let's get to this week's Top5: The Secret of the Security Safety Dance http://devcentral.f5.com/weblogs/macvittie/archive/2009/06/03/the-secret-of-the-security-safety-dance.aspx This week Lori...
What could you do with your code in 20 Lines or Less? That's the question I ask (almost) 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 in over your head. This week is apparently the week of encryption! I bring to you from my fellow DevCentralites a trio of encryption/hashing goodness via iRules. Two of today’s iRules were pulled from the samples page, one was recommended to me by Jason. All are very cool examples of iRules geekery and creativity, and they...
It’s been a great week at Interop in Las Vegas. I’m sitting here at the airport, sipping a frosty beverage and recalling the events from the past few days, and I have to say it’s been worth the last-minute trip. Each day I gave an iRules talk at the F5 booth. I got to do my song and dance in front of a crowd of people and try to express why iRules are so amazing to them, and why they should be using them. That’s pretty much a description of every day for me, it seems. The twist...
It’s Friday, the last day of work before taking off (literally) for Interop Monday morning. It’s been insanely busy trying to get ready to leave. So busy, in fact, that I somehow managed to miss T minus 2 in the series. Oh well, I was likely working on one of my presentations for next week, the presentation I gave this morning at 9, my blog, getting video gear together or … something. I leave super early out of Seattle, so you won’t hear from me until I’m settled into my room in Vegas. I’ve got my presentations finished, I’ve...
It’s Wednesday already, and it feels like the week has just flown by. I’m finishing up my presentations and getting things together to leave. I got a copy of the schedule for who’s going to be talking about what next week, and I’m quite pleased to be in great company. Fellow DC bloggers Lori and Alan will be there, along with several other sharp F5 folks talking about a myriad of interesting stuff. Hopefully some of them will keep the geek level high enough for our fellow engineer types. It’s always interesting to me trying to put together content...
It’s the second day of my Interop countdown, and there’s plenty of buzz coming from those getting ready for the show. I had a meeting with one of the people here helping to manage the show from our end to discuss time-frames and scheduling, when to be where, topics I’m going to talk about, who else is going to be there at similar times … even what shoes to wear. Apparently that’s caused many a newcomer to the convention scene grief. Lucky for me, I’m a seasoned vet and merely grimaced at the “he bought new shoes for...
Today I begin my five day countdown to Interop 09. I’m finalizing thoughts on presentation ideas, making lists of things to do both at work and around the house before flying down to Las Vegas on Monday for the show, and getting all of my other projects to a stopping point so I can leave them for a week. Interop should be a good show this year, as it always is. It’s huge, and there are always some interesting things to pick up there, as well as cool people to meet up with. I’ll be attending this year to...
From Web Accelerator to iRules to the release of the new Management Pack, this week's Top5 has it all. As always, there was plenty going on this week on DevCentral. These are my picks that you've just got to check out. Whether it's because they're incredibly useful, interesting, or just plain cool, all of these are worth a read, or listen, as the case may be. Here's this week's Top5: Announcing the Release of the F5 Management Pack for Microsoft System Center Operations Manager 2007 http://devcentral.f5.com/weblogs/sfisher/archive/2009/04/28/announcing-the-release-of-the-f5-management-pack-for-microsoft.aspx Aside from being the longest title of anything I've ever put...
As you've no doubt seen by now, BIG-IP v10 has brought with it all kinds of powerful new features. Among those are some very cool changes to iRules. I've already talked about the new class command, the killer new after command and a brand new namespace for you to utilize in your iRuling endeavors. These are far from the only additions to iRules in v10, however. If you're familiar with our iRules Wiki, then you'll likely notice that the new commands are already showing up in the appropriate places. They're both in the main commands page, as well as...
Whether you're looking for the best bits of v10 coverage or how you can make SAP and your F5 devices work together, this week's Top5 has what you need. The v10 content just keeps on coming, with some great additions this week. It's been a busy week and there are also some excellent non-v10 specific things that warrant highlighting, so you'll get a mix of both this week. Getting right to it, here's this week's Top5: F5 and SAP Integration - Auto configuration and monitoring under BIG-IP v10 http://devcentral.f5.com/weblogs/nojan/archive/2009/04/17/f5-and-sap-integration---auto-configuration-and-monitoring-under.aspx A welcome post by Nojan gets...
Lori's recent Dear Slashdot blog post was not only interesting and entertaining, but it was also very popular. So much so that it got picked up by, and posted on Slashdot. When you're one of the people responsible for the site hosting such a suddenly famous post, this is both fantastic, and a little bit scary. I'm always happy to see people writing compelling things that will draw attention to the other awesome stuff going on on DevCentral. Lori is fantastic at that, and this recent post is a prime example. By getting pushed out to a major geek...
Here we are, weeks after the announcement of BIG-IP v10, and the hits just keep on coming. It's been another busy, exciting week here in DevCentral-ville. There has been plenty going on to keep track of, and then some, so I'll try to distill it down a little, as always. That said, it's a shame to miss any of the great stuff that's coming out, so make sure to check the rest out for yourself. You're not here for all the content, though, just the best…well my Top5 picks, anyway. Here they are:

A couple weeks ago I started sending out tips for iRules users via twitter. I created a hashtag: #iRulesTips and I've been passing out tidbits of iRules advice / info on a pretty regular basis. The goal is to post something daily (or a couple times a day) but with the way things are going around here (see: super busy), I'm happy with "almost daily". Jason even saw fit to chime in with his own contribution, which is awesome. I'm hoping more people will add their own tips, tricks and advice as they see fit.
Here's a roundup of the...
It's an interesting relation that the more awesome, noteworthy content there is on DevCentral in a given week, the harder it is for me to narrow down what it is I want to call out in the Top5. That being said, this week is easily the toughest week to decide what to highlight in recent memory. With the BIG-IP v10 announcement dropping and the ensuing flood of killer content, there is an over abundance of options. That's a wonderful "problem" to have, though. I want to say this week especially that there are many killer things that are worth a...
To accompany the big announcement happening on f5.com today, we're rolling out all kinds of new content on DevCentral as well. We've got tech tips and blogs, forum posts and wiki entries...it's a veritable cornucopia of technical goodness to show off some of the awesome new features in BIG-IP v10. This release packs a punch, and it's definitely worth it to check out some of the new things you can do.
To help you get started, we've got a v10 page where you can go to keep your finger on the pulse of the new content we're pushing out surrounding...
Taking the rush of content on DevCentral in stride, I'm back again with 5 more items of interest for you that you really shouldn't miss. Hopefully the week's been good for you, whether that means bug-free code, trouble free system patching or happy clients. Things haven't really slowed down here since being turned "up to 11", so there's plenty to do and digest for everyone. Amidst the always churning stream of geeky goodness that DevCentral has to offer, there are rumblings lately of very cool things to come, so keep your eyes peeled. For now I offer you my picks...
When I said that things were cooking, and that the knob was only going to get turned up higher, I meant it. There has been so much going on in DevCentral land, in fact, that even the Top 5 was waylaid, temporarily. Never fear, though, it can be slowed but not stopped. Between new inner-workings for our site infrastructure, and an all new video-series documenting how we got there, plus the normal, awesome content the many contributors to DevCentral have been putting out, there's plenty to see. I'll make sure to hit the highlights for this week to see if...
What could you do with your code in 20 Lines or Less? That's the question I ask (almost) 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 in over your head. For this week's 20 Lines or Less I thought I might bring you some iRules that are fresh off the presses. I've been digging through the iRules forums today, trying to keep up with this outstanding community and their many innovations, concepts and questions. In doing so I got to answer some...
It's Top5 time again, and I swear it should only be Wednesday, yet the calendar says Friday. My week must have gone missing. If you see it, please let me know. I'm sure it's lonely and scared, and wants to come home. There have been so many things going on this week that it's been dizzying even for me to keep up with them…and that's kinda what I do, right? I will, however, attempt to sift through all the awesome contributions to DC to bring you the goodness you so rightly deserve, as is always my intent. This week we'll...
It's the 20th edition of 20 Lines or Less! Wait...is that a recursion loop or something? To celebrate this momentous occasion I'll still be asking What could you do with your code in 20 Lines or Less? But I'll be recalling my three favorite examples from the past editions of the 20LoL. These are things that not only made the list but were interesting enough that as I was going over them again they stood out to me as cool or compelling examples that were worth noting again, in case...
I can't believe it's only the second week of this year's Top5 series. There are so many things going on that it feels like it's been weeks since I wrote last. I know the output to the site has only been bumped up marginally but trust me, things behind the scenes are beyond busy trying to get things ramped up, polished and ready to push hard all through the year. This week saw some continued series', a couple of really interesting new blog / docs posts, and plenty of awesome action in the forums / wikis. Here's this week's Top5:
Accuracy...
Welcome to the first DCTop5 of 2009! It's a new year and that means you survived the holidays, the in-laws, the traffic jams, the elections, and if you live in Seattle, record breaking snow-storms. Congratulations, it's time to do it all over. There's been so much great stuff going on in DevCentral Land in the past 12 months that it's been hard for even me to keep up at times. So when I tell you that there's even more to come, and that we're turning up the dial further still this year, believe me when I say that it's going...
What could you do with your code in 20 Lines or Less? That's the question I ask (almost) 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 in over your head. This week has been fantastic here in DCLand. I've been sequestered in a room with the awesome minds of the DevCentral team for most of the week brainstorming, collaborating, sharing, and thinking up generally cool new stuff! It's always a good time when the team gets together and there are almost always...
Wired delivers an article that has a truly shocking image. Make sure you read the text in order from smallest to largest. What a great way to give a perspective of the kind of data that we're processing these days. That's a lot of bytes! I remember when downloading a 3 Mb file took "forever", and browsing the web I'd get really annoyed at how many images many pages forced me to load. Okay, I still get annoyed at that one, but that's not their fault. With the pipes getting bigger and the technology ever advancing, we're pushing more...
It's probably not much of a mystery, for those of you following along at home, that I'm a bit of a music guy. I play in a band, love music, listen to all sorts of it all the time, etc. etc. Not much of a logical leap from that is that I tend to also be a bit of an Audio/Video nut. I have a pretty decent home stereo, love the stuff, geek out about balanced inputs vs. 5-way bindings, speaker sensitivity, the pros vs. cons of working at a lower overall impedance, etc. That said, there is a particular...
Today I'm getting the chance to sit in with some fellow iRulers here at F5 and chat about this technology we love. This is a multi-day event, so I won't be able to sit in for every hour of it, but I'm trying to soak up as much of the geeky goodness as I can while I'm able to play with the cool kids. It's pretty hawesome to see this much knowledge and experience in one room, with such a broad range of perspectives and stories to tell about what the technology can do, where it should be heading,...
As some of the more astute, frequent DevCentral fliers may have noticed, there was no 20 Lines or Less this week. Fear not, brave souls. I was out on some planned vacation to bring some high-powered Rock N' Roll to the masses. I'm back now, of course, and you can expect the 20LoL to hit this week as normal. Heck, I might even double up this week, so stay tuned! Technorati Tags: Ramblings,F5,DevCentral,iRules,Rock and Roll,Colin Walker #Colin
