Installing Packages with Proxy

[rajbala_makar agilent com]

Hello:

Has anyone installed rpm packages via a proxy server? I am trying to install
packages through a proxy but it fails. If I set the ftpproxy ftpport
httpproxy and httpport in the .rpmmacros file,
it completely overlooks it and proceeds without the proxy and fails to
connect. If I pass those
parameters on the command line, it seems to go through the proxy but gives
one of following errors:

1) Package does not seem to be rpm file
2) Bad response received from server
3) File does not exist on server. (If I use an ordinary browser, I can
easily download the file and it does exist.)

I am using rpm version 4.0.2 and tried to download many packages freely
available on the internet but none of them succeeded.

Has anyone seen similar problems? Could someone advise on how to use the RPM
proxy support?

Thanks in advance.
