Greetings.

This is my first post here on EHN. Feels great to be here!

I ran into a problem while trying to scan my entire local network using nmap.

I am running nmap on a virtual machine using VMware (linux - Backtrack 5 r1)
VMware network settings on NAT

I also run Windows Xp sp2 virtually as a Target machine
Wmvare network settings on Host-only

Host is a windows 7 computer connected to a NETGEAR router and so on.

The script went something like this
" nmap -vv -F -T5 -sn 111.222.*.* "

And after about 50 seconds the network connection goes down.
I have to restart modem and router and then run ipconfig /renew to get the
internet connection back up again. Tried several times but i got disconnected every time.

Why does the connection go down ?


Thank you for taking your time reading my post

You were right. It works now. Thank you very much. I did not realize that the scan was powerful enough to do that to my network.
lesson learned.

Peace
