Thnx a lot phix. Now it shows that http proxy found but proxy authentication is required. But, I have entered my username and password in 'bashrc' as been told by roverrat. I think there also may be some mistakes that I have made. So, please go through my bashrc document which I am pasting with this reply and see if I have done it correctly.I have entered my username and password at the last line. Sorry for being such a pain in the a**.

# This file is sourced by all *interactive* bash shells on startup,
# including some apparently interactive shells such as scp and rcp
# that can't tolerate any output. So make sure this doesn't display
# anything or bad things will happen !
# Test for an interactive shell. There is no need to set anything
# past this point for scp and rcp, and it's important to refrain from
# outputting anything in those cases.
if [[ $- != *i* ]] ; then
# Shell is non-interactive. Be done now!
