NAME

smb-nat - NetBIOS Auditing Tool

SYNOPSIS

smb-nat [-d <debuglevel>] [-o <output>] [-u <userlist>] [-p <passlist>] <address>

DESCRIPTION

smb-nat is a tool written to perform various security checks on systems offering the
NetBIOS file sharing service. smb-nat will attempt to retrieve all information availible
from the remote server, and attempt to access any services provided by the server.

OPTIONS

-o Specify the output file. All results from the scan will be written to the
specified file, in addition to standard output.

-u Specify the file to read usernames from. Usernames will be read from the specified
file when attempting to guess the password on the remote server. Usernames should
appear one per line in the specified file. A sample username file can be found at
/usr/share/smb-nat/userlist.txt.

-p Specify the file to read passwords from. Passwords will be read from the specified
file when attempting to guess the password on the remote server. Passwords should
appear one per line in the specified file. A sample password file can be found at
/usr/share/smb-nat/passlist.txt.

<address>
Addresses should be specified in comma deliminated format, with no spaces. Valid
address specifications include:

hostname - "hostname" is added

127.0.0.1-127.0.0.3, adds addresses 127.0.0.1 through 127.0.0.3

127.0.0.1-3, adds addresses 127.0.0.1 through 127.0.0.3

127.0.0.1-3,7,10-20, adds addresses 127.0.0.1 through 127.0.0.3, 127.0.0.7,
127.0.0.10 through 127.0.0.20.

hostname,127.0.0.1-3, adds "hostname" and 127.0.0.1 through 127.0.0.1

All combinations of hostnames and address ranges as specified above are valid.

If no userlist or password list files are specified on the command line, a small set of
defaults are used. This list includes the following:

Usernames

"ADMINISTRATOR", "GUEST", "BACKUP", "ROOT", "ADMIN", "USER", "DEMO", "TEST", "SYSTEM",
"OPERATOR", "OPER", "LOCAL"

Passwords

"ADMINISTRATOR", "GUEST", "ROOT", "ADMIN", "PASSWORD", "TEMP", "SHARE", "WRITE", "FULL",
"BOTH", "READ", "FILES", "DEMO", "TEST", "ACCESS", "USER", "BACKUP", "SYSTEM", "SERVER",
"LOCAL"

The password guessing routines are written in such a way that all passwords are tried for
all usernames. Keep this in mind when using larger lists of passwords and usernames, as
the time required increases exponentially with the size of these lists.
