I am in a small fix. Just got GNS-3 and i have no idea how it works. I'm used to packet tracer and this is just out of my league. It keeps on requesting me to load an IOS version for the routers? Where do i get them?
Then it asks me to test the path with dynamips, whats going on here?
I really wanna get used to another network simulator apart from packet tracer.
Anyone with tutorials from scratch for GNS-3? Please help me understand this?
Thanx in advance peeps!

You will need a real Cisco IOS image file, the same used on real routers. If you don't have a real router with an IOS image in it's flash, then you will have to find a way to obtain an IOS image for you.
Sorry, can't post such links here as IOS images are copyrighted. Good luck.
I think thats a nice idea . Although there are already many tutorials out there. hmmm, I will start thinking about it, may be we could add an article to the fw.cx knowledgebase. But I can't promise any thing. I'm currently studying for my CCNA Wireless cert so it'll take time. In the mean time, these links might help:
1. This is a tutorial for starters on GNS3, make sure you click on HQ so you can the see small words clearly:
2. Allot of video guides on GNS3, browse the previous pages as they contain simpler labs, click the article you want then click the "watch video" button:
