Advanced Networking Courses for GNU/Linux?

Raj asks: "I am incharge of creating an advanced GNU/Linux course for my local User Group. We have a small but thriving software industry here. (I am from India). The aim of the course is to promote the usage of GNU/Linux among the local population by spreading quality information about GNU/Linux. After successfully taking our course the student should be in a position to manage the network of a small to medium company or academic institution. We are not looking at novices, but experienced users or sysadmins using other OSes. What I have in my mind now are the usual services: mail, DNS, Apache, Samba, CVS and so forth, along with internet security information like firewalls, SSH, SSL and the like. We have no time frame at this time. What services/daemons would you suggest. How deep should we delve into each subject. How should the practicals be handled. How should the course be structured. We will also be developing course materials for the course (which will be available under GPL) Are there any already existing documentation from which we can steal. Has any one attempted any courses like these before?"
