You can achieve much smoother downloads by using wget or gozilla/ getright. Wget, is a free program available for use from any Linux based machine in the CompLab domain. You can start using wget after you create a file called .wgetrc (yes, there is a period (.) in front of that filename) in your home directory with the following two line
http_proxy = http://jncproxy.intranet.jncasr.ac.in:3128/
ftp_proxy = http://jncproxy.intranet.jncasr.ac.in:3128/
Instead, you could type the following two lines on the command prompt:
setenv http_proxy jncproxy.intranet.jncasr.ac.in:3128
setenv ftp_proxy jncproxy.intranet.jncasr.ac.in:3128
then issue the command
wget -tinf < url leading to the file>
The commands wget --help or man wget might give you more options to use.
