Dear All, Kindly be informed that I am new in Linux world, and I have a strange story I would like to share with you. I was forced -in my work-to start providing support to an enviroment containing a server "Redhat 9" with the following installed application: postfix, postfix-out, cyrus, amavis-new, clamav, spam assassin, squid, squid-guard.

All that without any background with linux, so I started to studyand understand linux. That is OK. But I was informed one week ago that I have to prepare a new server with centos 5 and the same functions in the previous server to act as a hot standby for the provious one.

I am seeking any help in the technical field "configuration" and any advice for how to estimate the time for that project.

I Highly appreciate any help.
