Is it really required to show the User Name and Password in ASP.NET Error Page?

February 3rd, 2008 by koolb | No Comments | Filed in .NET, ASP.NET, Internet, Programming, Software Development, Web Development

I got the following ASP.NET error when I was browsing a local web site. The error is due to ASP.NET cannot authenticate using the User Name and password in the impersonate tag. Ther real issue is not the windows authentication problem. Because the reason for the error could be the domain server is down or the administrator has used an incorrect user name and password in the web.config.

But is it sill good to show the User Name and Password in the error message? You can argue that the developer has switched on CUSTOM ERROR MESSAGES and he has forgotten to switch it off at the time of deployment. But still is it really required to show the whole user name and password in the error? If the necessary ports are not secured, someone can easily login to the server and mess up the server very easily. (In this case only the port 80 and 21 is open and this user won’t have permission for FTP.)

Sri Lanka – Broadband QOS (Quality of Service)

January 29th, 2008 by koolb | 1 Comment | Filed in Broadband, Internet, Sri Lanka, Web

I have ADSL connection and Dialog WiMax connection at our work place. ADSL should have speed of 2Mbps, but it has around 800Kbps of real speed at off peak hours and on peak hours it goes down to speeds closer to dialup connection (around 100Kpbs). Dialog WiMax still maintains a good QOS. But still at peak hours it is 800Kbps for a 4Mbps connection and on off-peak hours it is around 1500Kbps. So I had the question whether the regulator of ISPs in Sri Lanka has rules on QOS for Broadband when they issue the operator license to the ISPs. But I couldn’t find any on the Service or Bandwidth QOC for internet or Broadband in the TRC web site. They only have some QOC Indicators to monitor Telephony services.

I found the following line below the tariffs when I was referring to Airtel India web site.
“* Speed indicated are only speed upto our ISP Node and are given on best effort bases as per TRAI guideline on Quality of Service for Broadband Service”
TARI is the Indian regulator. I checked their website on the guidelines they practice in India for Broadband services. I found “TRAI issues Regulations on Quality of Service Standards for Broadband Service” document which explained various indicators of QOS to protect broadband consumers.

I couldn’t figure out why the DSL and other broadband services license and tariffs are defined unconditionally in Sri Lanka. As I can understand from the TRC web site, any ISP can market a product indicating a huge bandwidth offering. But the QOS of the Network bandwidth they should offer is not enforced by the regulator. Basically they can share the network bandwidth with any number of customer since there is no minimum bandwidth QOS enforced by the regulator.

So that’s how it goes… we will hope someday TRC – Sri Lanka will take necessary actions to protect Broadband consumers.

Want to find out who is hosting your favorite web site ?

I always wanted to know the details of the web site if I find it interesting. I used to type www.whois.sc/<doman name> to find the domain information and SEO details. But whois.sc didn’t provide enough information about the Hosting Company. I found this new site which displays the Hosting Providers name for the given web site.

I’m Puzzled with Rediffmail

July 11th, 2007 by koolb | 1 Comment | Filed in Internet, Web

You must have seen the advertisements of Rediffmail. Specially during the Cricket Worldcup season they were advertising about Unlimited Storage on cable TV. They were advertising this even before the Yahoo mail announce of their Unlimited Storage offer. So I registered there for use it as my mail backup. But today I got “Your Rediffmail is full” message when I check my other pop accounts in Rediffmail.

-)

So I checked the help section on the account size. There is no indication of any limitations for other POP accounts. But it says..

1. What’s special About Rediffmail New?

New! Rediffmail is a free, fast & easy-to-use email. Offering you a storage space of 1 GB. It enables you to send 20 attachments at a time, with a total mail size upto 10 MB. The New Rediffmail has several features that make managing your email simpler, like drag and drop mails, instant preview, quick attach, mail search, easier to access address book, etc. It has powerful spam control and a much richer and more efficient interface.

So then what’s the meaning of the Advertisements ? Either the help section is not updated and the message I got is a bug Or they are big liars who can even lie on TV :-)

Dialog BroadNet – WiMAX Installation

July 11th, 2007 by koolb | 25 Comments | Filed in Broadband, Internet, Sri Lanka

Yesterday we got the WiMAX connection to our office from Dialog Broadband. Here are some pics which were taken when it’s installed.

WiMax Antenna.

Configuration was simple. They connect the laptop to the antenna / control unit using a web browser and Ethernet connection, like how you configure a DSL router. After that they configured the frequency for the cell. Even though, WiMAX doesn’t need line-of sight to work, they have to turn it around to get the maximum signal strength. They said even the reflection of the single would also work.

 

Initial speed tests

The purchased package was Ultra which should have speeds of 4000kb/s for download and 1000kb/s for upload (theoretically). These tests were done by connecting a single PC.

It doesn’t have the promised 4Mbps speeds, but currently it has fairly decent speeds. Hope they will maintain the same quality in the future. ( At least half of the promised bandwidth as its shared bandwidth :-( ) Anyway I got 450Kbps on FlashGet for downloads from download.com using 10 threads.

Here is a presentation from dialog which has the details of the available packages.

Most waited Dialog WiMax is now available.

Dialog has launched the WiMAX solutions under “BroardNet” brand name. You can now get WiMAX installed by contacting Dialog Broadband. I don’t know why they are not advertising it as their other products. The products are currently under testing, but following packages are available.
