Display CCNA curriculums locally

Once if we are allowed download zipped version of ccna curriculum (for example as an netacad instructor) we should be able run them locally without web server need. However there is a problem to display these curriculums by default as it contain embeded flash animation. This problem persists in different browsers (firefox, chrome, epiphany) for example.

Zmena preddefinovaného telnet klienta v dynagene za putty

Dynagen obsahuje cmd príkaz, ktorý umožňujú pripojenie na konzolu virtuálnych routrov priamo z jeho príikazového riadku, je to príkaz telnet.
