What's the full nmap command you're using?
I have started learning pentesting on a virtual lab i built within BackTrack 2.0
The lab consists of Win2000 & FreeNAS machines, and I am performing the testing from my BT2.0 box.
I am learning on NMap now, and when I try to do an OS detection (on the win2k machine) NMap fails to guess the OS, with the following message:
Could anyone help on this. I am using NMap 4.20Code:No exact OS matches for host
Thanks in advance,
I am using
Code:nmap -O -v xxx.xxx.xxx.xxx
How many ports are open on the system?
I guess you could also try:Which just tells it to guess the OS more aggressively.Code:nmap -O -v --osscan-guess xxx.xxx.xxx.xxx
The whole output you're getting might help as well. You can use -oN <filepath/filename> or just redirect stdout > <filepath/filename> for the output (or if it's really short just copy/paste it).
I know this is an old thread but for OS detection you would be better off using Xprobe2 instead of Nmap - It's much more reliable. Or better yet use them both but if there is a discrepency lean towards what Xprobe 2 indicates.
