NAME

       gns3 — a graphical network simulator

SYNOPSIS

       gns3 [-cdh] [file]

DESCRIPTION

       GNS3  is  a  graphical  network  simulator  that  allows  simulation  of  complex  networks and to launch
       simulations on them. It is an excellent complementary tool to  real  labs  for  administrators  of  Cisco
       networks or people wanting to pass their CCNA, CCNP, CCIP or CCIE certifications.  It can also be used to
       experiment  features  of  Cisco  IOS  or  to  check configurations that need to be deployed later on real
       routers.

       To allow complete simulations, GNS3 is strongly linked with :

           •   Dynamips, the core program that allows Cisco IOS emulation

           •   Dynagen, a text-based front-end for Dynamips

           •   Qemu, a generic and open source machine emulator and virtualizer

           •   VirtualBox, a free and powerful virtualization software.

       Important notice: users have to provide their own images.

       You may have to install a patched version of some emulators, please read the online  documentation.   The
       options are as follows:

       -h            Displays a help message

       -c            Directory where gns3.ini is located (default: ~/gns3/)

       -d            Display debug messages

       --version     Prints out the version and exits
