So, I’m doing my first attempts to write some simple apps in Adobe Flex using Flash Builder 4.6. One of funny things I came across was how to generate open file dialog windows and get name of the file which user picked from dialog windows. I guess still have to get used to specific way Flex applications are developed.

Here is quick code snippet of the tiny application which allows to open file dialog box and pick file. File dialog window will be OS specific.

So, finally I got 6 brand new Cisco 1142n wireless access points. They all are lightweight access points, which means that more less Wireless Controller is required to get them to work. Unfortunatelly due to many circumstances I have purchase of Wireless Controller delayed, so for now have to turn all of those into autonomus wireless devices. That means that IOS has to be replaced on those devices to allow 1142n be fully configured.

• Original software which came on devices was: c1140-rcvk9w8-mx.
• New software I had to deploy on all of them to make them autonomus is: c1140-k9w7-tar.124-25d.JA1.

But how the whole process happenes? Here are all steps I took to make lightweight AP become autonomus wireless access point:

When I got cisco 881w first time it was interesting experience. This device presented new concept which was different to model I knew so far, which is 871w. In 881w router module and wireless module are separated. With that being said, router configuration and access point configuration is separated as well. Also, each module (router and access point) has own IOS:

• c880data-universalk9-mz.152-1.T1 – router IOS
• ap801-k9w7-mx.124-21a.JA1 – access point IOS

As usual, first I connected device to console cable and attempted to configure it. Not being familiar with new concept it was a bit of a failure 🙂 So, eventually had to refer to documentation to find out what’s going on. Problem which came up was, how to access wireless module to configure it or even check if it’s there 🙂

So, finally after I did apply reading ability and spent few minutes with Cisco documentation I was able to access wireless module and configure it to provide wireless services in the air. Here is how that happend:

Recently was migrating RADIUS server on Windows from one machien to another. Once new serer was ready had to reconfigure Cisco router to authenticate remote users against new RADIUS. After pointing Cisco to new RADIUS machine made a quick test to check if router can authenticate without any issues. Here is how ot do it quickly:

Recently I was wondering how to list all available drives in Windows 7 PE Command Prompt. That happened to me when stuck in PXE boot command prompt window trying to find out what letter is assigned to USB stick I just plugged in. It looks like it’s not quite straightforward activity 🙂
