Bryan -

As you do doubt call tell, Linux/UNIX is not my area of expertise 
resulting in some basic questions.  Using the designations of Master and 
Slave, my Master and Slave have two different versions of RH software: 
RH 9 and Centos 4.1.  The Slave has it's own set of Services: HTTP, FTP 
and Samba along with other supporting Services.

Will this create a problem?
