By deploying Vyatta, users benefit from a flexible enterprise-class routing and security feature set capable of scaling from DSL to 20Gbps performance at a fraction of the cost [...]]]> http://www.firstdigest.com/2010/08/connect-vyatta-to-cisco-using-virtualbox-gns3/feed/ 5 How to emulate ASA in Ubuntu 9.10 and GNS3 http://www.firstdigest.com/2010/04/how-to-emulate-asa-in-ubuntu-9-10-and-gns3/?utm_source=rss&utm_medium=rss&utm_campaign=how-to-emulate-asa-in-ubuntu-9-10-and-gns3 http://www.firstdigest.com/2010/04/how-to-emulate-asa-in-ubuntu-9-10-and-gns3/#comments Wed, 28 Apr 2010 06:57:10 +0000 Calin http://www.firstdigest.com/?p=2633

Brainbump.net has an excellent and very complete how to emulate ASA using just the following components:

Ubuntu 9.10 – 32 bit Edition GNS3 v0.7 RC1 tgz Dynamips 0.2.8-RC2 binary for Linux x86 platforms Qemu-0.11.0 tar.gz Qemu-0.11.0 Patch ASA Binary Version 8.0(2) – (asa802-k8.bin)

GNS3 or Dynamips are very good at emulating a network topology  but unfortunately they cannot assure you with the tools capable to test the environment you just create.

Sure, it’s simple sometime to use a Loobpack interface on one of your edge routers to simulate an external network, but sometime is useful to have something connected to the router port.

Not because it is so complicate to operate, but because I didn’t saw any software like this one. GNS3 and Dynamips make a very good job together, allowing users to emulate a lot of network scenarios with different [...]]]> http://www.firstdigest.com/2009/02/gns3-how-to-create-frame-relay-hub-and-spoke-lab/feed/ 0 GNS3: How-to save multiple topology configurations for good http://www.firstdigest.com/2008/12/gns3-how-to-save-multiple-topology-configurations-for-good/?utm_source=rss&utm_medium=rss&utm_campaign=gns3-how-to-save-multiple-topology-configurations-for-good http://www.firstdigest.com/2008/12/gns3-how-to-save-multiple-topology-configurations-for-good/#comments Fri, 19 Dec 2008 13:33:12 +0000 Calin http://www.firstdigest.com/?p=294 GNS3 is an extremely useful tool if you are using Dynamips to emulate Cisco devices. It is a graphical environment in which even a newbie can do complex configuration by clicking and dragging routers, switches, connections into a topology that can be saved.
