Last week I needed to install twidge on a centos 5.7 server.
Truly, twidge is very simple to install into debian (or derived) linux distribution, but I found some problems while installing it into my centos server.
First of all you shall download the twidge binaries from here:
https://github.com/jgoerzen/twidge/downloads
the twidge binary requires libcurl-gnutls

simply type the following command:
Twidge is a full command-line client. It is designed to be useful when you’re sitting at a shell prompt. It’s also designed to work well with the Unix/POSIX/Linux shell scripting environment. It produces output in well-formed and easily-parsed ways, and has various features for working with piped data.

When you are working on embedded systems you couldn't have some useful tools to monitor the system resource;
In the following you will find a simple shell script I use when I want to monitor the network traffic on a Linux box.
Here it is the simplePing, it is a simple multithreaded ping implementation coded from scratch.
First of all we need some requirements to satisfy:
REQ_OS_01
simplePing shall run on Linux Systems.
REQ_OS_03
In this article I will show you how to write a simple TCP echo server.
The echo server is the simpliest server you can develop, it waits for data from a client and then sends the same data to the client.
With this post, the mini-serie dedicated to the simple udp client server ends.
Here you will find all the working source code and the Makefile. I hope this helps network programming begginers moving their first steps.
To download the source code simply click on the following link
Demonizing the Server
A server, to be a real server shall be able to run as a demon, it shall run in background and it shall not be linked to a terminal. To do this I'll add two functions to the simple server:
The Client.
The following code contains the implementation for the UDP client application that can send data to the server explained in the previous article.
The Server.
In this small series I'll show you how to write a simple UDP Client/Server system in a Unix environment using the C language. The server waits data listening on a port specified by the user, if the received data contains ".quit." string the server exits.
