GNS3 v0.8.5 Released - Graphical Network Simulator

GNS3 is an open source software that simulate complex networks while being as close as possible from the way real networks perform, all of this without having dedicated network hardware such as routers and switches.

Our software provides an intuitive graphical user interface to design and configure virtual networks, it runs on traditional PC hardware and may be used on multiple operating systems, including Windows, Linux, and MacOS X.

In order to provide complete and accurate simulations, GNS3 actually uses the following emulators to run the very same operating systems as in real networks:

Dynamips, the well known Cisco IOS emulator.
VirtualBox, runs desktop and server operating systems as well as Juniper JunOS.
Qemu, a generic open source machine emulator, it runs Cisco ASA, PIX and IPS.

GNS3 version 0.8.5 has been released.

This release fixes some problems introduced in version 0.8.4 as well as very old bugs. Improvements are in too.

Dynamips 0.2.10 is included in our Windows all-in-one package and OSX DMG, this version allows Crypto keys to be saved and it fixes a bug that prevented startup-configs to be loaded by c3745 IOS. Hooray!
New symbols for ASA, Qemu guest and Vbox guest.
Fixed a major issue that prevented to use the auto idle-pc calculation feature.
Implemented the Restore snapshot feature following Rednectar’s suggestions (http://forum.gns3.net/post20664.html#p20664)
Snapshots are now stored in a separate directory inside project directory.
Increased lowest and max zoom values.
Updated Italian translation.
Added Xshell 4 command lines in terminal settings.
Fixed issue with the contextual device menu.
Fixed bug when launching VPCS and there was a space in the project path.
Option ‘Use hypervisor manager’ changed to ‘Bind to external hypervisor(s)’ (logic is inverted) in IOS images and hypervisors dialog.
Checks: if VPCS is installed and if Dynamips is marked as executable.
Added instructions entry to Help menu.
Automatic opening of instructions file when loading a project.
Fixed Teraterm, SecureCRT and Konsole terminal command lines.
Added “-vga none” option to ASA Pre-configuration.
Updated the SecureCRT script to automatically reconnect if disconnected.
Fixed a bug with load-balancing on multiple external hypervisors.
Fixed issue when binding Qemuwrapper to a PC’s real IP address.
Various other small bug fixes.

Dynamips 0.2.10

A new version of Dynamips has been released. Major enhancements are:

The NVRAM configuration file private-config is fully supported, meaning crypto keys are correctly saved!
The c3745 platform correctly loads startup-configs.
The standalone tool nvram_export supports all known formats.
Extend hypervisor commands push_config, extract_config, and set_config (to be implemented in GNS3).
