By default, GNS3 uses Putty on Windows, xterm on Linux and Terminal on Mac OS X. But if using Windows for instance, you may prefer to use TeraTerm or SecureCRT (used in CCIE labs). Just download the terminal program you prefer and install it on your computer. Inside GNS3, choose Preferences under the Edit menu. Choose General in the left pane, then terminal settings.
To save you time, GNS3 comes with preconfigurated terminal commands. When choosing one of those preconfigurated terminal command, you detailed command to launch the terminal program will appear in a box. For instance, this allows you to adjust, if necessary, the command to point to the location where installed the program.
The current preconfigurated terminal commands are:
- Putty (Windows 64 bits)
- Putty (Windows 32 bits)
- Putty (Windows, included with GNS3)
- SecureCRT (Windows 64 bits)
- SecureCRT (Windows 32 bits)
- TeraTerm (Windows)
- Telnet (Windows)
- xterm (Linux/BSD)
- Putty (Linux/BSD)
- Gnome Terminal (Linux/BSD)
- KDE Konsole (Linux/BSD)
- Terminal (Mac OS X)
- iTerm (Mac OS X)
Please note that since Windows Vista, the telnet client is not automatically installed as in previous versions of Windows. To activate it, click on the Start sphere and choose Control Panel. Click on Programs. Under Programs and Features, click on Turn Windows features on or off. Click next to Telnet Client to place an x in the box. Click OK.
