GNS3 0.4.1 Release
GNS3 continues to get better every release. For those who haven't heard, GNS3 is Cisco network simulation emulation software that allows you to run the REAL IOS in a lab environment between multiple simulated emulated devices. This release now allows you to emulate 1700 routers and PIX firewalls! Killer.
There's plenty of talk that GNS3 will soon support virtual PCs in the lab environment.
I also stumbled upon another blog who has some great reading / tutorials on setting up and configuring GNS3: http://www.blindhog.net/. Kudos to all the video tutorials on the site!

One thing I've wondered, and I hope someone has an answer... How does GNS3 stack up to DYNAMIPS? Should I continue with DYNAMIPS or move to GNS3 ?

I believe GNS3 is more or less a graphical front end for DYNAMIPS

been working with Dynamips long time ago, its great tool, GNS3 as Shaun said is not nothing but graphical front end for Dynamips, rather than using a text file to creat your lab, you can use GNS3 to do the same job.
In hacki forum, for the last 18 months i managed to creat lots of labs, including Internetwork Expert CCIE R&S Lab, Internetwork Expert CCIE SP Lab, CCNA Labs, CCNP, Labs, and finally i managed to creat the big one =====> CCIE Voice :)
With this CCIE Voice Lab, you can practice over 70% of the CCIE Lab requirements.
In this Lab, i used: VMware, VMware for CCME, IPCC and Unity, IP Blue Phone and Cisco IP Communicator.
Thanks for this great blog, thanks to Jeremy "you are the man :)"
PS: Jeremy, cant we post here?

Can you post the URL to your forum page which has all these Labs?
Or even better, direct links to the config files?

Shaun, are you using a 2600 image? You'll have to unzip/unrar those first before you can use those.

Jeremy I know this is completely off topic but i could not find a way to ask you so i ill just post here and let you or a mod delete. I saw your write up on a "ideal ccna lab" what do you consider ideal for ccnp lab. I have read things like you must have atleast a 3560 or 3660 to test certain things and 1841 routers for some specific testing. Can you please let me know.
Thanks

@Shaun
Try using putty instead the cmd of win XP.
Go to Edit>Preferences and in terminal command put this in: start C:\putty -telnet %h %p (copy putty to c:\)
