This article is right on the number for getting Webmin install on the CentOs 5 operating system. The only thing I would recommend is getting the link to download the latest RPM by going to the Webmin.com and get the download URL from when the page is redirected to download the file. I accomplished this with a right click on the “this direct link” and copying the location to my clipboard and then pasting into my PuTTY session.
