Written By mediana saputra on Tuesday, 29 January 2013 | 00:17

GNS3 0.8.4 RC1 is now released. This is the last step before a final release and last chance to catch bugs.
Here is a quick list of the changes:
  • GUI improvements.
  • Drag & drop of multiple devices when pressing SHIFT.
  • Temporary projects are created by default.
  • Winpcap compatibility mode set in all-in-one, allowing it to be installed on Windows 8
  • Dynamips 0.2.8-RC5-community is now default on Windows.
  • Qemu 1.3 can be installed from the all-in-one (experimental). Qemu 0.11.0 is still the default.
  • Qemu 0.11.0 integrated to the DMG for Mac OS X (used by default).
  • Qemu 0.14.1 integrated to the DMG for Mac OS X.
  • Qemu monitor (to pause/resume) and user backend options (experimental).
  • Support for multiple flavors of Qemu: sparc, arm, i386, x86_64
  • SuperPutty command line support.
  • SuperPutty in all-in-one on Windows (optional).
  • VirtualBox interface numbering starts at 0 (e.g. e0 = VirtualBox interface 1 = eth0 on Linux).
  • Dash is now accepted for hostnames.
  • Fixed issues with ports reported as already in use.
  • Gray out VLAN box when selecting dot1q port type in Ethernet Switch.
  • Default delay for console adjusted from 0.5 to 1 second.
  • Default base console is now 2101 instead of 2001
  • Changed Dynamips default base UDP from 10000 to 10001
  • Mouse wheel scrolls the scene by default + options to deactivate the wheel or use it for zooming
  • Support for 36 network cards in VirtualBox (using ICH9 chipset)
  • Patching for Dynagen (see topic5659.html for details)
  • Wrappers improvements all over the place.
  • New baseconfig.txt
  • New option to save traffic capture in project directories.
  • Experimental auto IDLE PC calculation feature (requires Dynamips 0.2.8-RC5, included in Windows all-in-one and OSX DMG).
  • ASA pre-configuration.

What is GNS3 ? 
GNS3 is a graphical network simulator that allows simulation of complex networks.
To provide complete and accurate simulations, GNS3 is strongly linked with:
  • Dynamips, a Cisco IOS emulator.
  • 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.
GNS3 is an excellent complementary tool to real labs for network engineers, administrators and people wanting to study for certifications such as Cisco CCNA, CCNP, CCIP and CCIE as well as Juniper JNCIA, JNCIS and JNCIE.
It can also be used to experiment features of Cisco IOS, Juniper JunOS or to check configurations that need to be deployed later on real routers.
Thanks to VirtualBox integration, now even system engineers and administrators can take advantage of GNS3 to make labs and study for Redhat (RHCE, RHCT), Microsoft (MSCE, MSCA), Novell (CLP) and many other vendor certifications.
This project is an open source, free program that may be used on multiple operating systems, including Windows, Linux, and MacOS X.
Features overview
Important notice: users have to provide their own IOS/IPS/PIX/ASA/JunOS to use in their labs with GNS3.
