Port scanning using pbnj!

The site moved to root domain where all post are imported. Please go to http://pusheax.com/

Recently i installed Kali Linux on Vmware workstation. There was a tool called pbnj which can scan port and store results in mysql database. Sometime it is useful storing vulnerable assessment into database.But in Kali linux it is not installed as default. pbnj use nmap(with “-a [options] to scan network , I only use it store the result in database!

Let’s  see how to install and use it to scan port and store to database

root@find:~# apt-cache search pbnj
pbnj - a suite of tools to monitor changes on a network
root@find:~# apt-get install pbnj

Start mysql services on Kali Linux:

root@find:~# /etc/init.d/mysql start
[ ok ] Starting MySQL database server: mysqld ..
[info] Checking for tables which need an upgrade, are corrupt or were
not closed cleanly..


Let’s find all file related of pbnj :

root@find:~# updatedb;locate pbnj
/usr/bin/outputpbnj
/usr/bin/scanpbnj
/usr/share/doc/pbnj

I am going to use mysql so i am only interested in “/usr/share/doc/pbnj/examples/mysql.yaml” . So we need to edit this file to use correct username, password and database :
root@find:~# cp /usr/share/doc/pbnj/examples/mysql.yaml ~/.pbnj-2.0/config.yaml;
nano ~/.pbnj-2.0/nano config.yaml
# YAML:1.0
# Config for connecting to a DBI database
# SQLite, mysql etc
db: mysql
# for SQLite the name of the file. For mysql the name of the database
database: pbnjdb
# Username for the database. For SQLite no username is needed.
user: root
# Password for the database. For SQLite no password is needed.
passwd:""
# Password for the database. For SQLite no host is needed.
host: localhost
# Port for the database. For SQLite no port is needed.
port: 3306

In Kali mysql password is blank and username “root”. You should really change the username and password. But i am doing it without changing anything. Set let’s configure mysql:
root@find:~# mysql -uroot -p
Enter password:

We are ready to go now:

root@find:~# scanpbnj
Shell will be removed from the Perl core distribution in the next major release. Please install the separate libshell-perl package. It is being used at /usr/bin/scanpbnj, line 26.

Now Let’s scan port:

root@find:~# scanpbnj -a "-sS"  localhost
Shell will be removed from the Perl core distribution in the next major release. Please install the separate libshell-perl package. It is being used at /usr/bin/scanpbnj, line 26.

--------------------------------------
Starting Scan of 127.0.0.1
Inserting Machine
Inserting Service on 3306:tcp mysql
Inserting Service on 5432:tcp postgresql
Scan Complete for 127.0.0.1
--------------------------------------


Above the command option “-a” for nmap argument is “-sS”. Scan finished and hopefully result written to database. Let’s check:

root@find:~# mysql -uroot -p
Enter password:

There is another tool installed called outputpbnj which can be used to dump the result without manually logging to MySQL.

root@find:~# locate outputpbnj
/usr/bin/outputpbnj
/usr/share/man/man1/outputpbnj.1p.gz

root@find:~# outputpbnj
Shell will be removed from the Perl core distribution in the next major release. Please install the separate libshell-perl package. It is being used at /usr/bin/outputpbnj, line 27.

Okay, Let’s dump the latest result:

root@find:~# outputpbnj -q latestinfo
Shell will be removed from the Perl core distribution in the next major release. Please install the separate libshell-perl package. It is being used at /usr/bin/outputpbnj, line 27.
Error in option spec: "test|=s"
Error in option spec: "debug|=s"

wtf!

It is not working for as expected, No problem i am going to edit the “outputpbnj”(perl script). I have to remove “|” from “test” and “debug”. Kali linux use LeafPad text editor so “leafpad /usr/bin/outputpbnj” or you can use gedit or kate/kwrite(KDE) . Then searching for “test|=s”:

GetOptions(
%options,
'type|t=s', 'file|f=s', 'lookup|l=s', 'both|b',
'query|q=s', 'names|n', 'desc|d', 'sql|s', 'list',
'dbconfig=s', 'configdir=s', 'dir=s', 'data=s', 'qconfig=s',
'test|=s', 'debug|=s',
'help|h' => sub { help(); },
'version|v' => sub { print_version(); },
'both' => sub { $bothOutput = 1 },
)
or exit 1;

Just remove the pipe “|” from “test” and “debug”, It should be :‘test=s’,    ‘debug=s’  Now save and run :

root@find:~# outputpbnj -q latestinfo
Shell will be removed from the Perl core distribution in the next major release. Please install the separate libshell-perl package. It is being used at /usr/bin/outputpbnj, line 27.
Tue Mar 26 19:12:23 2013 localhost mysql up unknown versiontcp
Tue Mar 26 19:12:23 2013 localhost postgresql up unknown version tcp


It is possible save the output in different format. For example:

root@find:~# mkdir pbnjr
root@find:~# outputpbnj -q latestinfo -t html -f pbnjr/report.html
Shell will be removed from the Perl core distribution in the next major release. Please install the separate libshell-perl package. It is being used at /usr/bin/outputpbnj, line 27.

root@find:~# cd pbnjr
root@find:~/pbnjr# ls
report.html
root@find:~/pbnjr# iceweasel report.html
root@find:~/pbnjr#

Another curiosity that i can use only one query(“-q”) or there are more…. no, I can use many command:

possiblevuln
sshmachines
allservices
services
unknown_version_up
unknown_banner_up
machines
mdump
servicesup
service_audit 

All the query command is available in outputpbnj script(With Description)!

These kind of tool really useful for vulnerability assessment. pbnj is really a nice tool.
