Hi,

Is there an open source network mapper that can scan and crawl an gateway device and/or subnet and diagram every host it detects without using network credentials. Because there is very little documentation about the way the network is configured, a tool that can automatically draw a topology could help a lot. The machine I am using to document the network is win 8.  I am using paint and gliffy.com.  any resources or suggestions will be helpful.

Thanks.

uh...no  the tools need the network credentials to get the details of #1) what the device is and #2) the details of how this device is connected to other devices.  Best you can do without network credentials is port scan a given IP address range and determine what ports each device is listening on.  NMAP will do that, but that is not going to draw a diagram for you.

Never seen gliffy.com before - that is interesting.  I use Visio which has 1000s of stencils for vendors equipment.

I'm sorry to be the bearer of bad news.  Generally mapping out a network for the first time requires manual intervention and network sleuthing to figure out what is going on.
