Using <a href="https://xmlrpc.rhn.redhat.com/XMLRPC">https://xmlrpc.rhn.redhat.com/XMLRPC</a> as the URL , I invoke the "up2date.login" method with "system id file" (an XML string basically) as it's parameter. As a result of this , I get the list of channels I am entitled for. For example, [rhel-x86_64-server-5, 20100112174250, 1, 1] : Here the first entry in the tuple is the channel name and 2nd entry is the last modified time for this channel. 2. Once I get the channel information : I go ahead to get the package details using "<a href="https://xmlrpc.rhn.redhat.com/XMLRPC/$RHN/rhel-x86_64-server-5/listPackages/">https://xmlrpc.rhn.redhat.com/XMLRPC/$RHN/rhel-x86_64-server-5/listPackages/</a><last modified time for the channel>" As a response to this method, I get package attributes such as name , version , release , arch , size, epoch . But no checksum information is returned as a result of this call which causes the problem. I am not sure of why mirroring RHN updates is done this way. I could not co-relate the code written (XML RPC methods used) with the list of API provided here. <a href="https://rhn.redhat.com/rhn/apidoc/index.jsp">https://rhn.redhat.com/rhn/apidoc/index.jsp</a> I believe the code was written long time back and was (in fact is ) fairly stable. :-) However, I am also open to re-implementation of the same in case there are some better approaches. So any suggestions are most welcome.
