Playing with the Packeteer PacketShaper

February 25th, 2009 Michael Farnum

I just got an eval PacketShaper 2500 for a few days from my local Bluecoat SE (Bluecoat bought them a few months ago).  I actually used to work with these boxes just about everyday a few years back.  I worked for a company that built apartment complexes for college students at a lot of major universities across the country.  We acted as the ISP for the students, and these complexes would house 500-1000 students.  These kids went EVERYWHERE on the Internet.  There were so many different types of traffic flowing around on those networks, and there was A LOT of it.  Students were constantly complaining about the slowness of there Internet connection.  Every day I was getting calls with someone griping.  So the company would spend a little more money and I would bond another T-1 to the two or three we had.  We would see improvement for MAYBE a day (two if we were lucky), then that pipe would fill up.

So we decided to bust out with the Packeteer boxes.  I would put in a box, and we would see every type of traffic imaginable within about an hour.  Back then Napster and Kazaa were the big bad boys.  These kids would kick off 10-20 downloads before they went to class and just let them run all day.  Multiply that by at least 100 students, and that traffic would just consume the pipe completely.  When that happened, the poor students just trying to surf the web for actual schoolwork would suffer horribly.

So when we started cutting that traffic off at the knees (either killing it entirely or making the bandwidth limit so low that it wasn’t worth it), things changed dramatically.  All of a sudden people were able to surf the web.  They could still download their music, but it would take a little longer (who cares if it is downloading while you are in class).  Everything just improved, and the calls almost completely stopped.  Of course, you always had the spoiled brat who complained because his DSL or cable at home was always fast and his online game never suffered there.  It was always fun trying to explain to some punk getting a degree in underwater basket weaving that he didn’t have 900 other people trying to download porn and music on his DSL at home.  What was more fun was explaining that I didn’t give a crap if Elf Quest was fast or slow and that he should probably be doing homework instead of screwing around with games.  But I digress…

Anyway, good stuff.  Click on the picture below to see some of the traffic on my little network (some purposefully generated by me).

Clickjacking

October 6th, 2008 Michael Farnum

This post has no technical value.  Just experimenting with how much traffic I can get by putting the term “clickjacking” in a post. :)

But seriously, if you want to know anything about it, go listen to Martin’s podcast interview with Jeremiah and Rsnake.  You can also go over to Computerworld and take a look at the Q&A.

So…

AT&T Broadband @ Starbucks (and a few McDonalds)

April 11th, 2008 Michael Farnum

I was in Dallas a few weeks ago for a few sales call, and I met my sales guy in local McDonalds parking lot.  I needed to jump online real quick (still can’t get a broadband card OK’ed), and I noticed that the McDonalds had a AT&T WiFi sign on their front window.  I decided to try it since I have AT&T broadband at home, and I’ll be darned if it didn’t work.  Had a nice sign on page where I could input my broadband user name and password.  Very nice. 

Of course, there are not a whole, whole lot of Micky Dee’s that have WiFi.  So I usually find myself in a Panera Bread because, unlike Starbucks, they have free WiFi.  However, Panera’s are not near as prevalent as Starbucks, which often leaves me in a quandry (in my not-so-humble opinion, Starbucks should pay for my Internet access if I buy a coffee and a scone – believe me, I very rarely leave a Starbucks without at least having a tall non-fat no-whip mocha). 

But a few months ago I heard that AT&T was getting in on the action at Starbucks as well, and they supposedly were offering free WiFi to AT&T broadband customers.  SWEET.  So I went to few Starbucks over the last few weeks, but I never saw an AT&T WiFi sign.  Oh well.  I figured it was taking them a while to get it all in. 

Well, being the dumba&& that I sometimes am, I never just tried to see if they had it going by simply connecting to wireless and seeing if I saw an SSID out there.  So a couple of weeks ago I decided to give it a go.  And there was not an AT&T SSID anywhere.  Dang!  Oh well, I guess I’ll have to wait some more. 

But I really needed to get on the Internet (I had a proposal that was due, and I was about to be on the road for 4 hours), so I hooked up and prepared to shell out some money to T-Mobile.  And then, what did I see up in the top right-hand corner of the T-Mobile page (kinda small and inconspicuous, BTW)?  There was a AT&T Broadband image that beckoned me.  I clicked, signed on (just like McD’s), and I was on.  OH HAPPY DAY!! 

Now, I have not tried this at any other Starbucks yet, but my assumption is that it was not just this little Starbucks in Ennis, TX (25 miles south of Dallas on I-45).  So I am happy.  Now I can go to Starbucks, buy my mocha, and then surf to my heart’s content.

trying out Safari for Windows

March 31st, 2008 Michael Farnum

I have heard some good things about Safari for Windows, so I am going to try it out.  And since they are pushing it with the new version of iTunes (not quite as heavy handed as the push out to Mac users – I had a choice to decline it), I figured what the heck.

The first load was pretty slow, but that is to be expected the first time it comes up on a new system.  It loaded much quicker the second time around.  I’ll play around and let you know what I think later on.

Update.  I said later, but here are a couple of thoughts / impressions right now:

  • The load status of webpages is in the address bar, which is different for me (maybe that is standard for Mac users). 
  • Intense Debate (the new blog comment system that I am beta testing) seems to work fine with it.  Intense Debate also works great with Firefox on my system, but IE seems to choke on it quite a bit.
  • The fonts seem to be a tad hazy.  Not as crisp maybe
  • iGoogle looks pretty good on it
  • The redlines under suspected misspelled words is much more noticeable
  • I still like IE7’s new tab feature rather than needing to hit CTRL-T
  • I don’t like that there is not a history arrow in the address field.  Instead you have to click the history menu.  Maybe that is just because I am used to it, but I like that feature on IE and Firefox

Maybe some more later.

OK, more:  Where is the area that gives you a preview of the link you are about to click on?  I can’t see where I am going!!  Oops… OK, found it.  You have to choose View > Show Status Bar.  This is becoming more like a twit post than a blog post. :)

SkypeOut will no longer be free

December 18th, 2006 Michael Farnum

December 31 is the last day of free SkypeOut calls (calls using Skype to regular numbers outside the Skype network). I know a lot of people use Skype for calls. I personally use it for conference calls from the office quite a bit. I can switch to my mobile or office phone easily, but I know some people who use it for podcasts, and it makes it quite efficient.

The good news is that SkypeOut is pretty cheap. It will be $29.95 a year for unlimited US and Canandian calls, which I think is dang good. If you buy now, you can get it for $14.95.

So, anyone planning on signing up?

Really sweet speed test site

August 17th, 2006 Michael Farnum

Thanks to Pito at salas.com for the link to this site.  Very sweet looking speed test site.  And you can choose speed test servers all over the world.  Of course, they could be downloading malware on your PC, but hey, it is still cool!
