From Basta Computing:
Rasputin simulates network activity to help keep your Internet connection alive. Rasputin is very simple to use and works discreetly in the background.
In case you're curious about the product name Rasputin, it is inspired by the 19th century Russian monk who had survived several attempts on his life, just as this software should help you survive ISP attempts to close your connection. Moreover, RAS refers to Remote Access Service, which is the Windows service used to connect your computer to the Internet.
I am using a 56k modem on a Compaq 1.1Ghz computer with CompuServe as my internet provider. Over time I was becoming increasingly annoyed at getting cut off the internet at any sign of idleness. Finally I decided to try out Rasputin 1.6,a simple pinging devise in the hope that it would help aleviate the problem. The trial period lasted 30 days. I lost track of the time and on the 31st day was jolted back to reality when CompuServe started cutting me off again. Rasputin had done it's job well. At that point it was very clear to me that I would need to buy the program....right away! Only $10 for a program that worked flawlessly was a STEAL!
