Hey the procedure that is told above is absolutely outdated
The new way is
First download sifyclient other dependencies from
http://202.144.65.70:8090/.
You need to have alien before hand
TO download alien type "sudo apt-get install alien"
Then by alien convert the rpm packages into deb
Download the tar.gz file form
http://202.144.65.70:8090/
then go to terminal
type tar -xvf sify_bbclient-3.0.tar
go to terminal
there navigate to the folder to which it is extracted
For instance you have done it on the Desktop
Then
open terminal
Type
1) "cd Desktop"
2) "cd sify_bbclient-3.0"
3) "sudo ./install.sh"
This will install the client
Then type in "sifyconnect"
and this will start the sify client
