error with db_autopwn

[tim.e.mcguire at gmail.com (Timothy McGuire)]

Hello,
I am trying to run db_autopwn against a vmware instance of Damn Vulnerable
Linux.  I've studied the instructions at
http://blog.metasploit.com/2006/09/metasploit-30-automated-exploitation.html

I didn't follow the install steps there because the required parts seem to
be in my Windows install.

I have a database named metasploit2 populated by the postgres.sql script
that came with the metasploit framework
Here is what I am doing:

load db_postgres

db_connect superuser:superpassword at 127.0.0.1:5432/metasploit2

db_nmap -v -A 192.168.226.129    (this populates my services table with
interesting ports)

> > db_services
[*] Service: host=192.168.226.129 port=22 proto=tcp state=up name=ssh
[*] Service: host=192.168.226.129 port=80 proto=tcp state=up name=http
[*] Service: host=192.168.226.129 port=631 proto=tcp state=up name=ipp
[*] Service: host=192.168.226.129 port=3306 proto=tcp state=up name=mysql
[*] Service: host=192.168.226.129 port=6000 proto=tcp state=up name=X11

db_autopwn -t -p

and result is:
[-] Error while running command db_autopwn: undefined method `type_oid' for
nil:NilClass

etc....

So, any hints would help.  I don't see any exploits that would specifically
match any vulnerabilities I have in the target, so I don't expect the
command to compromise the system, but I'd like to know what the errors mean.
