OK, I'm showing my noobness again. I installed Nmap and Nmapfe. I tried running them to look at my network, but I cannot seem to get it running correctly. When I have it scan a single IP address of a machine that I know, such as 192.168.1.3, it runs fine. When I try to scan my complete network, it starts running a loop stating that the operation is not allowed. It continues to run this loop until I manually stop it. I opened guarddog, and added ping, icmp redirect, and traceroute in both local and internet, but that did not work. I tried 192.168.0.0/24 as well as 192.168.1.1/24 and 192.168.0.0/16. I am also trying to run this as a user, as well as root in both X and the CLI.
I'm sure that I am overlooking something, but I cannot seem to figure out what it is. If anyone has any suggestions, I would greatly appreciate it.

Thanks,

I'm bad at english, so i can't really figure out what do you want to do.
If ya want to scan all host on your network: nmap 192.168.1.*
There are more fine examples at the end of the nmap manual page.

I tried that, along with all of the options I found in the man pages. Here is the closest I got to get it to run:

neuromancer:/home/hank# nmap -v -sS -O -P0 "192.168.0.0/24"

I stopped the loop, but it would run forever. Is the Operation not permitted" reporting on my machine, or the other machines on my network?

Thanks,
