How to install Cygwin in Windows7 64x and run Linux applications inside Windows

Cygwin Running NS3 in Windows 7Cygwin is a development environment similar to Unix one and has command-line interface to work like in Linux but inside the Microsoft Windows Operating System. Cygwin eliminates the overhead of installing an entire Linux OS for running certain applications. There is a native integration of Windows-based applications and softwares to work in Linux or Unix like environment, thus it is not necessary to install Linux only to fun your simulating program. Wine, WINdows Emulator, on the other hand is just the reverse application to Cygwin – Wine allows us to run applications developed primarily for Windows OS in other operating systems, say Mac OS or Linux.

In order to run or install native Linux or Unix based simulators like NS2 or NS3 (Network Simulators) and OMNeT++ (not a native though) in Windows (without installing Linux), you will need Cygwin. Read Tutorial: How to install ns-3 in Windows 7 using Cygwin by Jason.

Facing – The server encountered an internal error! Solved here.

The other day we got our site with tones of unverified and broken links. Joomla, the award winning open-source CMS, was the web software of choice for our main site www.ekendraonline.com. internal-server-error

We have been using sh404SEF- editor’s choice and the most popular one until recently. It is a business, the Joomla component that used to generate search engine friendly urls and was the free, all of sudden the genius guys or the makers of sh404SEF turned out to go business, the component was charged 35$ for a single access for a year. So, we decided to drop out sh404SEF and suggest those conscious people like us NOT to use sh404SEF simply because there are several other free Joomla components for generating Search Engine Friendly URLs.

The Internal Server Error we received, by chance, happened to be after the case of sh404 above. But might not be the one due to that component. Below is the exact copy of what is displayed on our website pages.

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, webmaster@ekendraonline.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.


Apache/2.2.13 (Unix) mod_ssl/2.2.13 OpenSSL/0.9.8k DAV/2 mod_auth_passthrough/2.1 FrontPage/5.0.2.2635 Server at ekendraonline.com Port 80

Now, let’s explore and study to fix the problem. Since this is a server problem or the server configuration problem in our host (Bluehost), we will be dealing with the same. We are taking about Linux hosting only. (unsure about other hosting platforms)

The first thing you need to fix or check if 500 Internal Server Error can be handled is to rename the server configuration file htaccess.txt to .htaccess only (simply right click the file htaccess.txt to rename and modify to .htaccess) in the file manager of the cPanel (we guess).

The problem is most likely to be an issue with DOS carriage returns / line feeds versus what the Linux server expected. There are various tools create .htaccess files online, but generally notepad or any text editor will do the work. Ensure to test your site thoroughly after making an adjustments to the .htaccess file.

And remember to hackup the file htaccess.txt before acting.

Integrate BuddyPress and bbPress seamlessly- a tutorial

We assume that your installation of BuddyPress was successful. If your host’s cPanel has support for SimpleScripts, then installing BuddyPress directly from SimpleScript would be a better ides. Alternatively, you can install multiuser MU WordPress ( or buddypress according to your knowledge). Ensure you have also installed bbPress since we are going to integrate buddypress & bbpress, remember you can have a same database or different one for them.
