Free port software for linux

Port Scanner provides a tool to check for open ports.

Port Scanner will try to connect on every port you define for a particular host. If a connection is made, it will try to read any data returned.

This product is intended for individuals to test their own equipment for weak security, and the author will take no responsibility if it is put to any other use.

Amazon sell many books on Security that will enhance your ability to keep your computer secure.

The Windows version has been withdrawn. Apologies for this, but it is too popular and uses my bandwidth up too quickly. If anyone want to host the binary for me, I will happily post a link here. It should also be possible to compile Version 2.1 for Windows.

Whats New in this release:

.(QT) Takes multiple port ranges.
.Minor bugfixes.

Sys::PortIO is a Perl module to perform direct port I/O from Perl.

SYNOPSIS

use Sys::PortIO;

port_open($portnum);
write_byte($portnum, $value);
$value = read_byte($portnum);
port_close($portnum);

This module provides a Perl interface to the low-level port I/O operations provided by Linux, FreeBSD, or OpenBSD. Among other things, this is useful for writing Perl scripts that interface with parallel, serial, or joystick ports.

jPortScanner is a Java port scan utility.
Requires Java 1.4 or greater (for its use of regular expressions)

tar -xvf jPortScanner.1.0.4.tar
cd jPortScanner.1.0.4
make
make install
To run type:
jPortScanner
Enhancements:
- which was causing localhost scans
- added Makefile/Install script
- Fixed bug with timeouts

TCP port scanner is a network scanner for Linux.

Installation:

1. Install - become root and gunzip/tar tcpscan-X-Y-Z.tar.gz.
2. Type ./confugure , make
3. Type install
4. Enjoy and try type tcpscan localhost
5. To get help - run tcpscan without parametres.

Usage:

tcpscan [-f] [hostname || IP_address]
tcpscan [-f] [first_IP_address] [last_IP_address]

Bash Port Knocking is a set of scripts that use standard Linux tools to acheive a port knocking system. A Web page is used to open ports, and an email is sent every time the port knocking sequence is successfully made.
Main features:
- Uses custom scripts to begin firewall and ipmasquerade for multiple connections. This can be used as a gateway for ethernet provided Internet Connectivity in addition to supplying port knocking services.
- This script creates a web page that can be used for port knocking. This page can be used locally if the browser is using a public/anonymous proxy.
- This scripts emails the above created browser page to a specified email recipient each time the port knock sequence is successfully acheived.
- This script logs successful port knocks but denies knocks that hit a port designed in the initial scripts. This allows the script to be closed automatically if someone is hitting your computer repeatedly trying to automatically open the ports and allows you to close the ports if youve completed a log in or other desired action.
- In its current state it has run successfully for quite some time and been tested repeatedly with both anonymous proxy and remotely by the author for opening ssh.
- It allows the user to control the depth of the logs searched to function in a very low usage enviornment or a very high use enviornment as desired.
- It sorts the knocks by knocking address to prevent possible denial of service.

Ports Tree Explorer (PTE) is a small tool that allows you to navigate through your /usr/ports tree, showing you information about a selected port, tree view, software categories (/usr/ports main dirs) and finally allows you to install a selected port using childs for the installation.
PTE Allows you to monitor background installs and allow you to perform certain operations related to your software ports tree, with a plain and simple GUI requires almost minimum shell interaction.
Newer versions will include CVS updates off the ports, managing/modifying a specific port, see available FLAVORS and finally specify compilation options for this port. Ports Tree Explorer is written in perl/tk and its working (tested) on Open BSD. PTE is free and improvements, adjustments etc. are more than welcomed.
PTE aims to be an easy to use tool. Plain and simple as possible, functional for new users of /usr/ports tree along with experienced users that get bored often.
The scope of this project is to provide an easy way to use/maintain and install programs from your ports tree.
At the current stage, we aim to be usable and all the required functions be implemented and work.
After this goes to a stable release, security enhancements and extra functionality will be added.
Main features:
- Ports Category separation
- Ports Program separation
- Description of Port
- Install selected port
- History of executed commands (Installations)
Enhancements:
- Kill a background install.
- Changed the state of background install from Started to Finished (when the install is actually finished)
- Save history to file.
- Direct output from the fork to the output window.
- Support for other ports, like NetBSD, Free BSD ports.

Just Another Port Scanner (JAPS) is an easy to use, bare-bones TCP port scanner. JAPS requires the GTK+ library to run. I created JAPS because I felt it would be a fun project and I wanted to learn GTK+ programming basics.

To compile an install JAPS just type make.

Todo
Add subnet scanning
Add progress bar
Display service name next to port number in results box

Device::ParallelPort is a Parallel Port Driver for Perl.

SYNOPSIS

my $port = Device::ParallelPort->new();
$port->set_bit(3,1);
print $port->get_bit(3) . "n";
print ord($port->get_byte(0)) . "n";
$port->set_byte(0, chr(255));

A parallel port driver module. This module provides an API to all parallel ports, by providing the ability to write any number of drivers. Modules are available for linux (both directly and via parport), win32 and a simple script version.
NOTE - This actual module is a factory class only - it is used to automatically return the correct class and has not other intelligence / purpose.

DRIVER MODULES

NOTE - You MUST load one of the drivers for your operating system before this module will correctly work - they are in separate CPAN Modules.

L - Direct hardware access to a base address.
L - Linux access to /dev/parport drivers
L - Run a script with parameters
L - Pretending byte driver for testing
L - Pretending bit driver for testing
L - Windows 32 DLL access driver
DEVICE MODULES ^
L - An example that can talk to a printer
L - Simple JayCar electronics latched, addressable controller
L - SerialFlash of bits - useful for many driver chips
