GNS3 VirtualBox Edition

admin — Fri, 12 Aug 2011 05:20:09 +0000

Thanks to the great and massive contribution of Alexey Eromenko, alias "Technologov", VirtualBox is now supported in GNS3. Alexey has also added many improvements and fixed bugs, which make his unofficial GNS3 VirtualBox Edition the best GNS3 to date and the one we recommend to use while we are merging Alexey's contribution to our official branch.

Also, the next official version of GNS3 should be released around October or November, besides merging Alexey's contribution, GNS3 is going to undertake major changes (redesigning, code refactoring, new unit testing etc.) with the arrival of a new team of programmers from EPITECH Paris to work on the project. This should definitevely helps GNS3 to reach a new level of usability and we are very enthusiastic about it. This will be the topic of our next news in a couple of months.

GNS3 VirtualBox Edition 0.8.1 is available on our download page. Please see below for the changes.

Major Improvements:

VirtualBox support (v4.1 required)
Wireshark Live Traffic Capture
Basic IPv6 enablement
Basic Netbook enablement
Architecture: On Windows, GNS3 now runs from source code
Architecture: PEMU is now moved from GNS3 core to a separate component. (PEMU will be part of Windows "All-in-One" installer)
Architecture: Resolved conflict with Debian's built-in GNS3 package. On Linux, setup is no longer needed.
Dynagen Console got a massive rewrite / cleanup
Russian translation got a major update

Other Changes and Fixes:

Windows Setup was rewritten from scratch
Changed Default Qemu Ethernet Controller from "e1000" to "Realtek 8139" for Windows XP compatibility.
GUI: Swapped AUX & Console icons - more convenient to have "console" button near "start" button.
Disallowed to hot-add new links to running Qemu.
Fixed VM states coherency between Dynagen's Console and GNS3.
Several fixes for using GNS3 with external qemu/vboxwrappers (multi-host distributed topologies)
GUI: Disabled Linux features on Windows hosts. (KVM, NIO_VDE, NIO_UNIX and NIO Linux Ethernet)
GUI: Disallowed connecting devices with incorrect link types, such as Frame-Relay switches with Ethernet cable.
Fixed the problem of filled WIC slots in Routers (0.7.4 Regression; UldisD's case)
Fixed SecureCRT (SARS' case, minor bug; Windows hosting only)
Terminal Emulator Settings: sorted & hide non-platform-related options
Fixed AUX port error messages
Fixed translation file generator
Dynagen Console: 'hypervisors', 'ver' and 'versions' commands are now merged into just 'ver'.
Dynagen Console: 'exit' and 'disconnect' commands are now merged into 'clear topology'.
Dynagen Console: Removed non-working commands: 'shell', 'cpuinfo', 'py', 'conf', 'confreg', 'hypervisor', 'end', 'send'

VirtualBox / vboxwrapper backend features:

FlexiNetwork: Link hot-add/hot-remove
Traffic Capture
Suspend/Resume VMs
Instant reboot
"automatic" NIC type (just mirrors existing NIC type)
Network statistics (Bytes Transmitted / Bytes Received)
View of Guest OS IP addresses, by retrieving data from Virtual machine (if GuestAdditions installed)
GuestControl execution; send commands from Dynagen console
Double-click on VBOX VM brings it's display window to front.

Free GNS3 Video from CBT Nuggets and established partnership

admin — Sun, 02 Oct 2011 03:30:31 +0000

Recently I learned, that Jeremy Cioara, CBT teacher and Super-Star, whom I respect very much and like his educational videos,did a video about our GNS3 network simulator project.

We have established a form of marketing partnership between The GNS3 Project and CBT Nuggets. (Open-Source project and a commercial entity).

We created the GNS3 network simulator for education, so our product and CBT Nugget's videos are complementary in the field; we're not competitors. The marketing partnership basically says that CBT releases GNS3 video for free, but we give the credit + link to their website + logo.

New Free GNS3 Video from CBT Nuggets

Video Provided by CBT Nuggets

My own opinion: Jeremy Cioara (from CBT Nuggets) is absolutely the best teacher of advanced Cisco material I've ever listened. I absolutely recommend their videos. Here are the demo versions of those videos (first 5 minutes free)

Enjoy and Best wishes,

GNS3 0.7.4

admin — Mon, 11 Apr 2011 20:10:06 +0000

GNS3 0.7.4 is released. This is a minor release before working on a major one and includes the following things:

Greek translation
Hypervisor allocation per IOS type
Improvements on Ethernet Switch (dynamic remapping of VLAN or type)
Adaptations to support Dynamips 0.2.8 RC3 community
Integration of a loopback manager for Windows

Dynamips 0.2.8 RC3 community version released

admin — Mon, 11 Apr 2011 10:11:13 +0000

We are proud to release Dynamips 0.2.8 RC3 community which is a new and unofficial version of this great software made by Chris Fillot. It is provided without warranty, based on a development version and improved with patches wrote by various people from the community.

It brings many improvements and bug fixes. The most noticable are:

Online Insertion and Removal (OIR) support for c3745 (NM-4T only) and c3660.
c7200: support for jacket card (C7200-JC-PA) and support for PA in slot 7.
New Multicast NIO (not implemented in GNS3/Dynagen).
64-bit support for MacOS X (stack alignment).
NIO traffic statistics (packets/bytes in/out).
QinQ support in integrated Ethernet switch (not fully tested).
JIT code sharing system (only MIPS ported at this time). Works only with a "unstable" compilation.
"udp auto" NIO to avoid fixed port allocation which can easily fail (to be implemented in GNS3/Dynagen).
Possibility to open multiple consoles for a same IOS.
Able to set system id at runtime in cli mode using -I <systemid> or set_system_id in hypervisor mode (to be implemented in GNS3/Dynagen). This is for routers 1700, 2600, 3600, 3725, 3745 and 7200 (not npe-400 or npe-g1 or 2). System id format is dependent on router, e.g. -I 4279256517 or -I FTX0945W0MY (these are the current defaults).
AUX port for routers 1700 to 3745 now works.
Cisco Pagent and CallGen image support for c1700, c2600, c36xx, c37xx, c7200 NPE-100 to NPE-300.
