Deployment using findks via a Red Hat Proxy Server fails

Issue

• Deployment using findks via a RHN proxy fails
• We have worked out a solution for deploying RHEL systems using the Satellite

• The solution works great but when using a proxy the solutions fails

  • Systems are registered using cobbler. The MAC address is used to identify a system

  • The findks option is used to find the corresponding kickstart image in the cobbler database, eg.:

    append initrd=initrd.img ks=http://<satellitehostname>/cblr/svc/op/findks kssendmac text noipv6
    

  • The kssendmac option provides the Satellite with a HTTP header 'X-RHN-Provisioning-MAC-0'.

• The solution described before does not work with a RHN proxy
• In our test lab we are trying to install a system that is reachable from a RHN proxy, but that is not reachable by the RHN Satellite.

• The kickstart URL is modified to use the Proxy instead of the Satellite, eg.:

  append initrd=initrd.img ks=http://<proxyserverhostname>/cblr/svc/op/findks kssendmac text noipv6
  

• The problem with this solution is the kickstart file that is generated with the findks script

• It is identical to the file that is generated by the Satellite, which means the fresh installation tries to contact the Satellite instead to the Proxy
• Since the Satellite is not reachable the installation fails
