  • How to get the RHEL binary using the provided XMLRPC library - HTTP Response '401 Authorization Required'

    Posted on

    Hi,

    I'm trying to get the rpm binary on my subscribed RHEL-6-Server machine using the XMLRPC calls to the URL "https://xmlrpc.rhn.redhat.com/XMLRPC".

    I did the following :

    • Generated the systemid file after running the command
    rhn_register
    
    • Using the up2date.login call, I logged-in using my rhn account (/etc/sysconfig/rhn/systemid file).
    The corresponding HTTP Request-Response exchange is :
    
     --- request ---
    
    POST https://xmlrpc.rhn.redhat.com/XMLRPC
    Content-Type: application/json
    
    
        up2date.login
        
            
                
                     ****  System ID File Content  ****
