Ask HN: What to do on a workshop lesson at a networks and communications class?

I am a student at a network and communications class, at a public institute of Vocational Training in Greece. The Greek ministry of education has not yet released a study guide for my specialty because it was merged from 2 others (A. Networks & B. Communications). It is not clear what we are supposed to do at the workshop lesson and thus we, the students and the teachers are at a point of brainstorming. Bellow are what we already done in previous semesters on the same lesson and also the titles of all the lessons we have already done and will do:

Workshop Lesson (all the following at entry level): Html/Css, Java, C, SQL

Other Lessons (in Titles): Introduction to Computer Science Pascal Computer Architecture Operating Systems 1 Data Communication Electronics and Digital Calculations Telecommunications Operating Systems 2 Network Management 1 Computer Networks 1 (Wireshark) Network Safety Telephone Centers Network Management 2 Installation Networks (Structured Wiring) Mobile Telephony Computer Networks 2

The workshop lesson takes place at a lab with about 10 computers (2 students per computer) with windows 7 and Ubuntu (with some kind of server connected to them) installed. Also for any addition software we want to install, the administrator needs to come and type his password. Last but not least I don't think the computers could handle VM's.

So far we have come with a few ideas: Cisco Packet Tracer (Educational) PHP (But we will lose much time on installation of Apache, PHP, Mysql, etc and we want something more close to networks and communications; we have a general idea of programming and it would be waste of time to learn again the if, case , while, etc)

Truth is we don't have the infrastructure we need to do what we really studying like setup and configuration of networks but we try to work with what we have.

The question is: What would you teach at this class, at the workshop lesson?
