I attempted to download an online book hosted on a website using wget in Linux. Generally it works with any website. Strangely with the site I am trying, wget command fails with following error.

bash# wget http://dummy.net/orelly/weblinux2/php/

bash#

Is there a way I can get rid of this problem?
