Red Hat Linux FTP (RHEL Server Series) Available download FTP

Recently, I have been studying Linux. The first time I came into contact with RHEL 4 as was a long time ago. So this time I still use the RHEL series. But now, RedHat only provides versions that were downloaded from earlier versions, many of them are in verycd, but the EDK link is closed in the school ~~ I can only continue to Google, and finally found an FTP provided by netizens. I have read all the mainstream versions, which are now included for future convenience:
