Free icmp port number 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The Windows version has been withdrawn.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.

Convert::Number::Digits is a Perl module that convert Digits Between the Scripts of Unicode.

SYNOPSIS

use utf8;
require Convert::Number::Digits;

my $number = 12345;
my $d = new Convert::Number::Digits ( $number );
print "$number => ", $d->toArabic, "n";

my $gujarti = $d->toGujarti;
my $khmer = reverse ( $d->toKhmer );
$d->number ( $khmer ); # reset the number
print "$number => $gujarti => ", $d->number, " => ", $n->convert, "n";

The Convert::Number::Digits will convert a sequence of digits from one script supported in Unicode, into another. UTF-8 encoding is used for all scripts.

Active port forwarder is a software tool for secure port forwarding. Active port forwarder uses SSL to increase security of communication between a server and a client. Originally, it was developed to forward data point to point.
However, the need for bypassing firewalls in order to connect to internally located computers influenced the further development of the project.
AF is dedicated for people, who dont have an external ip number and want to make some services available across the net.
Moreover, zlib is used to compress the transferred data.
Using one, permanent data/control channel with flow control / packet buffering provides good performance and reasonably small latency.
Running afserver does not require root priviledges, nor does it use threads or other processes.
Enhancements:
- The bug in the ip_listen function (visible on the systems without IPv6 support) has been fixed.

The ICMP Hostname Tools for Linux include a responder daemon, a lookup tool, and a nameswitch module to handle ICMP host name functions.

The NSS module caches all requests (including failures) and honors the TTL value sent by the responding host. It uses a configuration file called /etc/nss-icmp.conf, which controls different aspects of its operation:

* timeout – Sets the timeout in milliseconds for ICMP host name queries, by passing the -t option to idnlookup.
* nocache – Disables the cache.
* ttlnotfound – Sets the TTL for not-found cache entries is seconds. The default is 5 minutes.

Both icmpdnd and idnlookup need to run as root, due to the fact that they use ICMP. Thus, idnlookup needs be installed SUID root.

Parallel port powerSwitch project is a TCP/IP server to control a parallel port power switch.
pp_powerSwitch is a TCP/IP based server, which controls a power switching device through the parallel port. Besides Java, I used a bit C to handle the parallel port I/O.
I use it for controling heating, lamps, computers, coffee machine and other things (device has eight ports).
Main features:
- multiple connections
- user athorization
- cron-like scheduled switching
- reads configurations from file
- configurable log output
- simple port descriptions (add a short description to each port)
- remote shutdown

Port forward is a java application which gives you the ability to open tunnels between your local computer and a remote ssh server. With Port forward, tunnels can be created both local or remote.

Examples:

1. Open a local tunnel to reach a remote mysql database

- Your application needs to connect to a remote database server (mysql for example), but the database server (remote.server.example) is not configured to expose mysql to internet directly.
- Port forward will open a local port (3306) and redirect the connections to remote.server.example ssh server
- The remote.server.example ssh server will connect to its local mysql server

2. Open a local tunnel to use a remove VNC desktop

- You want to connect to your home computer which has a vnc server but from work, the firewall blocks vnc connections (generally on port 5901)
- If you have a ssh server at home, you could use it as bridge to connect to a client in your home:

Your position internet your linux ssh server ->>
-->> you client with vnc (192.168.0.40)

you office
internet >

3. Open a remote tunnel to pilot a remote linux server non reachable through internet
In this example, you will create a remote tunnel, this will give the remote man to connect to and reach you.

I used this example if I have to pilot a remote pc, but this pc has no static IP or is behind a firewall
The good solution is to activate port forward on the pc to be piloted and to connect it to a server we can access.


PC 1 (to be piloted) --||||-- firewall ----- internet ----- accessible-server

Installation:

Be sure java is in you classpath
tar zxvf portforward.tar.gz
cd portForward
sh run_linux.sh

CppUnit is a C++ unit testing framework. CppUnit project started its life as a port of JUnit to C++ by Michael Feathers.
Main features:
- XML output with hooks for additional data
- Compiler-like text output to integrate with an IDE
- Helper macros for easier test suite declaration
- Hierarchical test fixture support
- Test registry to reduce recompilation need
- Test plug-in for faster compile/test cycle (self testable dynamic library)
- Protector to encapsulate test execution (allow capture of exception not derived from std::exception)
- MfcTestRunner
- QT based graphic test runner
