OS Fingerprinting not going to db_hosts

[ceefus]

I'm running metasploit v3.4.2-dev [core:3.4 api:1.0] on BT4 R1. I'm trying to play with my virtual network and autopwn. The database connects with Postgres 8.3 and I can see db_hosts but when I try to fingerprint the OS of the target machines it does not go into my db_hosts.

I have tried:
db_nmap -v -sV -O xxx.xxx.xxx.x/24 -oA Namex

&

use auxiliary/scanner/smb/smb_version

but neither of them will put the OS in db_hosts. My buddy is running BT4 PRE and he can't get it to do it either. I tried this on my work VM farm & my home VM farm and I can see the OS output but it never goes into db_hosts.

Does anyone have any ideas?


Thanks in advance.

I followed chapter 4 nearly verbatim.. It will show the OS when I use smb_version and use -O on nmap but it never goes into my db_host. I have tried it on 2 machines now but I still don't get the info..
