[SATLUG] RHEL4 License Key

[Sean I]

I need a bit of help, I am deploying RHEL ES Version4 on 8 identical Blade
servers.  They want me to install on one, lock it down and get it ready and
then use mondorescue to clone it on the other 7 blades (pretty much just
change name and IP the rest of the systems remain identical).  All that is
easy except I do not know how to change the license (I do not usually use
RHEL).  I have all 8 keys that came with the software (8 copies of RHEL ES
4) but is there a redhat tool that allows you to change it so they can all
connect to the rhn?

Thanks
Sean
