In this article, i will show you how you can emulate Adaptive Security Appliance (ASA) in Ubuntu Linux 9.10 ( Karmic Koala ).Also be aware that ASA does not 100% work in Qemu but that’s enough to play with it.I used “asa802-k8.bin” for this tutorial.You can create Shell  Script (first_start.sh) yourself  or scroll through the [...]

Recently,  a fellow blogger James Key passed his CCIE Voice Lab in SJ and got his digits.He has been posting regularly about his progress on his blog and finally, he has made his mark. Congrats to him for dedication to his goal and also to his family for encouraging him throughout his journey.Send him your [...]

With the Skype for sip beta program now in open public domain , there are open integration options available for Cisco Routers esp. CUCME as well as CUCM.Both SIP Digest Authentication as well as IP authentication are supported. For those businesses eager to test integration , you can test service by setting up a Business [...]

So here it is - the loooong awaited GNS3 release. It is a RC, but if you’ve run GNS3 betas then you’d be interested in running this and giving it a shot. In my opinion the GNS3 development team does a great job with betas to the final release. I havent found enough instabilities in their betas that made me wait around until the final release - of course YMMV

Here is the official post from the GNS3 team.. Submitted by admin on Sat, 11/28/2009 - 16:56

This is it, a new release of GNS3!

The main new feature is the integration of the Juniper router emulation using Qemu. Preparing a JunOS image is not as straightforward as an IOS one and you will surely need to read the how to.

Others features are:

* Qemu integration.
* ASA integration using Qemu.
* An undo/redo framework (not fully debugged tough).
* Translations in Italian and Farsi (thanks to our contributors).
* Various bugs fixes and improvements.

I know many of you are very enthusiast but keep in mind this is a release candidate, so expect some bugs. (please, post your bugs report on the forum, under Development -> Bug reports).

Oncoming features and fixes can be found in the TODO file.

Hope you will enjoy to make Cisco/Juniper mixed labs.

Hi everyone!

I’m pleased to introduce the GNS3 technical blog where you will find interresting articles about the development of GNS3 and other related information. The first post is about how to emulate JunOS on your PC using Qemu, a topic I’m working on for the next release of GNS3. At the moment, the integration of JunOS with GNS3 is manual but the next version will provide an easier method.

Original post from GNS3.net

The initial post is awesome as the GNS3 team has cracked open the ability emulate Juniper JunOS using Qemu.

See the post Olive reloaded or how to emulate Juniper routers

For those of you who have been struggling integrating GNS3 with ASA as well as with JuniperOS , there is good news for you. Now, you can integrate GNS3 natively with ASA/Juniper OS using latest GNS3 release. This feature has been provided by integrating GNS3 with Qemu. Both JunOS  as well as ASA can be [...]

I have been doing some extensive UCCX scripting quite recently. One of the best ways to approach UCCX scripting is to explore Script Repository in your UCCX Server with some ACD(Automatic Call Distribution ) and AA(Auto Attendant) sample scripts.However, this might be very basic for most users out there. If you want to dig deep [...]

Extension Mobility was introduced to CUCME beginning with release 4.2 .With Later Releases e.g 4.3 and beyond, some enhanced features were added e.g the ability to use the phone user interface to configure personal speed dials directly on an EM phone . Some of feature enhancements include : Configurable Automatic Logout Automatic Clear Call History Privacy on an [...]

Recently, While searching on Cisco Unified Mobility Advantage (CUMA) and Cisco Unified Mobilitiy Client (CUMC) for my Apple iPhone, I came across a pretty comprehensive and detailed guide which covers setting up CUMA Server and integrating it during Post-install to many associated application servers e.g Microsoft Active Directory , Exchange Server , CUPS , CUCM [...]

Phone Proxy is a superset of TLS proxy where not only signaling but also media is secured for communication.It supports a Cisco UCM cluster in mixed mode or nonsecure mode.Configuration that i will show here will have UCM cluster in non-secure mode.TLS/SRTP will be terminated on ASA proxy server and TCP/RTP will be communicated between [...]

“Hello World!’ - Hey so it’s been while since posting last and some things are getting back to normal since the move. One of them is my office Very happy about that! One thing that has not gotten back to normal is routine studying - I’m so far behind from my goal - but I do have 2 months before the year is out to complete the BSCI - Don’t know if I can do it though. I’m just not in the zone. Well anyway, here is a lab I’ve been meaning to put together to share with you all. It’s a lab involving NAT/PAT and Overload .. Sean shares this with us.

I setup this lab up to help me better understand ACLs (Standard, Extended, Dynamic, and Reflexive) and NAT’ing (e.g. Overload, Dynamic, and Static).

The IOS used is a 3640 version 12.4. The special topic about this lab is I did this on a Mac Book Pro and used the TAP/TUN drivers to attach my MBP into the simulation. So this config requires that GNS3 be run as root (e.g. sudo) in order to allow the TAP device to be created. Information on the TAP/TUN drivers for OS X can be found here:

Thanks for the lab dude! You too can share labs - You can either create a post here on the site with your lab and send all files necessary to the lab to postmy AT gns3-labs.com. You can also skip posting it and just send all files necessary to the lab to postmy AT gns3-labs.com. Thanks to all the help from contributors like Sean - you call help keep this site going!

Routers Used: 3640

IOS: c3640-ik9o3s-mz.124-25b

Feature of Topology: Static NAT, Dynamic NAT, Overload NAT, Network Address Translation (NAT), Port Address Translation (PAT), Access Control Lists
