# snmpscan	scan snmp services for commonly known snmp communities
#
#		This script can automate the scanning of your network to
#		check for possible "vulnerabilities" regarding your snmp
#		community "passwords" for access to your routers and/or
#		snmp services.
#
#		Even though you may be running a unix snmp daemon that
#		does not allow control of any services, access to the snmp
#		service provides alot of information about the machine it
#		is running on. Afterall, that is what snmp is for.
#
#		All routers and machines running snmp services should be 
#		protected with a password composed of upper and lower case 
#		characters, numbers, and symbols. Those that aren't can be
#		easily brute forced.

This script is for UNIX hosts running perl 5.003 and up.

The use of this code is simple:

	$ snmpscan

You must first edit your file 'hosts' and put the hosts you wish to scan.
This file is simple a list of hosts on each line. Input from TDS can work.
Just copy your output files from TDS (toplevel domain scanner) into one
file called "hosts". 

There is one option to snmpscan. Append "-dict" to the commandline and it
will use the input in the file dict.txt as bounds to check versus the
communities. You can either fill this with dictionary words, or commonly
used communities. If you have found a prime list that works for you, send
them to me!

	$ snmpscan -dict

This code requires Net::SNMP in order to work. This module can be
downloaded from CPAN, or you can install it as root automatically with the
CPAN module as follows:

	$ perl -MCPAN -e shell
	CPAN> install Net::SNMP

To install it manually, get it here:

	http://www.cpan.org/authors/id/D/DT/DTOWN/Net-SNMP-2.00.tar.gz

	Then untar it:

	$ tar zxvf Net-SNMP-2.00.tar.gz

	Run perl Make:

	$ perl Makefile.PL

	And run the regular make install

	$ make install

That should complete the install.

This program should be pretty self-understanding. If you should have any
problems email me at knight@phunc.com. Suggestions, bugfixes, etc are
welcome as well. Flames go to dev@null.com.

You can get the latest release of this and TDS from
http://www.phunc.com/tools or ftp://ftp.phunc.com/pub/phunc/tools.
