Linux Download Password Protected Large ISO Images [ Authentication Credentials ]

I‘m trying to download an ISO image for Enterprise Linux from RHN or Novell Suse. Both providers have placed ISO images behind paywall. I need to provide authentication credentials before downloading all files. How do I download ISO files using the wget command with user name and password?

You can use the Linux wget command to download large ISO files. The wget can provide user name and password for HTTP/401 Unauthorized headers using the following syntax:

wget --http-user=RHNUserName --http-password=RHNPassword 'https://content-web.rhn.redhat.com/rhn/isos/....'

OR

wget --http-user=NovellUserName --http-password=NovellPassword 'http://download.novell.com/sendredirect....'

In this example, I’m downloading SLES 11 SP1 AMD64 workstation from my personal account, enter:

wget --http-user=MyUSERID --http-password='SecretPassword' 'http://download.novell.com/sendredirect?target=%2Fprot%2Fx4q3cbksW7Q%7E%2FSLES-11-SP1-DVD-x86_64-GM-DVD2.iso&buildid=x4q3cbksW7Q~&fileid=X4FjnhU0Qk4~&mirror=AkamaiHost&nohost=false'
