Related to GNS3

I downloaded it the first time. However, i can not really find out how to use this application. Read the guide regarding it but still couldn't get rid of some stupid errors while running this application. Apart from such introduction, i need to ask some questions
about it.

1) GNS3 does really require a "real IOS image" for each device on the menu? If so, how could i configure all Cisco devices on packet tracer without doing such a thing?

2) I put the baseconfig.txt as IOS image for c2600 router for example, nothing happens on the router. Why not? Does it have to
be .bin or .img?

3) I can't seem to find how to assign IP addresses to devices in this application, tell me how?

1, You need an IOS image, because GNS3 is emulate a router and run the real IOS. Packet Tracert is a simulator which is look like the IOS.
2, baseconfig: gns3 use this file as a default startup-config.
3, without an IOS image you cant do anything. as soon as you load the IOS, right click on the router's icon and choose terminal.

I don't use GNS3, I use Packet Tracer. In Packet Tracer, the routers & switches have the IOS already loaded on them. You can use a couple of other IOS on the routers & switches. These IOS's are available on the TFTP server. Place the TFTP server on your workspace, place a router on the workspace, connect the two, configure your IP's on the interfaces, then use the CLI commands to copy the desired .bin from the TFTP to the device Flash, reload. Yer all set.

Also....go to YouTube....do a search for "packet tracer".....you'll find quite a bit of videos working with Packet Tracer.
Here's one site on YouTube....this guy uses Packet Tracer in most of his videos -

+1. This is exactly how I learned to use GNS3.

Thanks for the replies, guyz. However, my main purpose to use a little complex program is running the SDM with this application. However, it still shows the same two errors.

I've seen Todd Lammle post on this forum that instructors have received a new topics list that doesn't include SDM (or something to that effect, I don't remember the exact wording and can't find the post now). But it's still listed on the official exam topics, so I wouldn't go into the exam knowing nothing about it. You can probably memorize screen shots out of the book for what little SDM there is in the exam topics anyway. Or look at it this way. If it's not on the exam and you learn it, will it hurt? If you don't learn it and it is on the exam, will it hurt?

@thedrama: What are the error messages you're getting? Without knowing the exact message, it will be impossible to know what is causing it.

Finally can access the forum again - haven't been able to for a week

Its in the old not the new one.

There's a thread in the CCNA security forum.

Last date to sit the old one is 30th september 2012.
