yum through proxy with authentication, username & password proxy support

See the Basic setting & then try to apply the following ---

http_proxy="http://username:passwd@192.168.1.1:3128" /* if PROXY host is http://192.168.1.1 & PROT is 3128 */
ftp_proxy="http://username:passwd@192.168.1.1:3128"

Don't forger to export the environment variables!!!!!

yum through proxy, squid proxy, cannot connect through proxy, yum behind proxy

If you are behind a proxy, yum will not connect via proxy.
(Remember you had to put proxy information in Firefox Web Browser to connect with internet).

So, for yum, you have to put the same settings.

First, set the environment variable(s) for yum:

http_proxy="http://192.168.1.1:3128" /* if PROXY host is http://192.168.1.1 & PROT is 3128 */
ftp_proxy="http://192.168.1.1:3128"

Second, export the variable:

export http_proxy
export ftp_proxy

Third, run your yum command!!!!
