4 Summary High school The assignment Lower level applications and techniques Advanced web application ConclusionQuestions?

5 The assignment CCNA lab's Router simulators Router simulators Remote lab network security Practice at home using an advanced web application

6 The assignment Lower level applications and techniques Tom Bosch Tom Bosch Telnet session with routers Telnet session with routers Virtual computer and remote desktop Virtual computer and remote desktop Web application Robin Njotea Robin Njotea PHP with MySQL database PHP with MySQL database

7 The assignment Network topography:

8 The assignment Inside dotted line: Lab topography Outside dotted line: Administrative network Async module: Translation telnet - serial connection

9 Summary High school The assignment Lower level applications and techniques Advanced web application ConclusionQuestions?

10 Lower level techniques Network Address Translation (NAT) Translate internal IP address to external IP address and visa versa Disadvantage: As much external IP addresses as internal IP addresses needed

11 Lower level techniques Port Address Translation (PAT) Translate several internal IP addresses to one external IP address with different port number Advantage: Use one external IP address for several internal IP addresses Internal addressExternal address : : : :2101 ……

12 Lower level techniques Telent session (Async) Start-up with empty routers Batch file: Move log file Move log file Reload router script Reload router script Remove “old” static translation from router Remove “old” static translation from router Generate random port number Generate random port number Add “new” static translation Add “new” static translation

13 Summary High school The assignment Lower level applications and techniques Advanced web application ConclusionQuestions?

14 Student login View a CCNP lab  Advanced routers  Pix

15 Reservation  Different lab’s different reservation pages Insert reservation in a database Holding time  Carry out batch files Advanced web application

16

17 Carry out lab  Get reservation information from database Which lab which application Batch files  Log each session  Reload each application for reuse Advanced web application

18

19 Summary High school The assignment Lower level applications and techniques Advanced web application ConclusionQuestions?

20 Conclusion Research different aspects Keeping it simple makes it harder 2 large parts: Lower level applications and techniques Lower level applications and techniques Advanced web application Advanced web application Bring these parts back together

21 Summary High school The assignment Lower level applications and techniques Advanced web application ConclusionQuestions?
