GNS3 Network Emulator

Notes

Gns3 > Edit > Preferences > Dynamips

• Enable ghost IOS support - memory mapping allows loaded images in RAM to be shared between other routers

Connect to Router console

GNS3 (dynamips hypervisor) is listening on IP 127.0.0.1 ports starting from 2501. Therefore to emulate AUX serial connection we need to telnet 127.0.0.1 port_number. See an example below:

piotr@piotr-x:~$ telnet 127.0.0.1 2504
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
Connected to Dynamips VM "R3" (ID 3, type c7200) - AUX port
Press ENTER to get the prompt.

Cannot find New Project window in Ubuntu multiple screen setup

A: Show all desktops overview and drag the windows in physical view of the main screen. Usually your laptop screen is smaller than an external monitor causing that a part of the screen is only logical and does not have a physical screen size.
