Open Source C Networking Software for Linux

DIET-PC (DIskless Embedded Technology Personal Computer) is a software kitset enabling IT professionals to build an open source GUI appliance based on commodity x86 (PC), PowerPC (Mac) or ARM (handheld) hardware, using an embedded Linux methodology.

Lan Core is a free & open source software that lets you to build a thin client network on a Windows operating system. It was originally designed to work in a server or workstation with Windows XP Professional using the native remote desktop protocol.

Agnix is an educational, network operating system kernel. It is ideal starting point to learn about operating systems. The main goal of the project is to provide a network kernel fully compatible with the Linux Kernel in the system call layer

pipeworks is a benchmarking tool for pipelines that is very similar to pipemeter. It writes its stdin to its stdout, while reporting the data flow rate to stderr. It features adjustable block size and bandwidth limiting capabilities.

Electronical interlocking system for modular model railroad layouts.

With ttyutils, a user can watch and control a remote user's terminal session, record the terminal session to a file for later playback. or write scripts to automate interactive terminal programs such ftp

CitrixTS4Linux is a GUI remote access server application written in C and C++ to allow access to RPM-based Linux terminal servers via the free Citrix ICA client.

Piggyback Data Transfer Protocol (pdtp) is a protocol for transferring files over a terminal session. Initially the session works like a normal terminal. File transferring "mode" is activated by running a client on the remote server.

RTelnet is a reverse Telnet, it's increadably useful to get behind firewalls and NAT's or routers running ip masqurading. very useful for remotely admin someones PC remotely when they don't know how to do anything like opening their firewall.

The project works on a kernel module and inetd service to allow the usage of a distant RS.232 port through a network connection.

SWAL is a program that can launch as a service (or standalone) and monitor other services and control other programs. Written in C++ and might have some .NET components (planning on a linux port)

Live Security/Forensics Linux Distribution, built from scratch and packed full of tools useful for vulnerability analysis, penetration tests, and forensic analysis.

A simple tool help you to execute some commands on a remote machine(server) just as on your local machine(client). Get and put files from and to server are supported too.

XSockets - open, lightweight and highly portable library of universal and eXtensible Super Sockets for point-to-point communication. A unified API for many communication methods between programs and/or devices (e.g. TCP/IP sockets,serial link,pipes,IrDA)

cyclades-serial-client is an RFC 2217 compliant client that works with servers such as Cyclades Terminal Servers and sercd. It creates a virtual serial port which connects to the server over a network.

I'm a HW Support and used cacti, zabbix, but they are too "strong", sometimes I just want to know server "worked fine", and show me a basicly load-average chart, that's enough. And the other hand, I need run command (like: "top", "iostat", "date" etc.) remotely and show it out to the webpage. The hwmonitor(writen in C) is a simple daemon, you can define some command-name(like: show_top= top -b -n1), telnet to this daemon and input your def-command(like: show_top), hwmonitor will return the info. And hwclient(include in this project, writen in C) connect to hwmonitor, input a define command-name to get server load-average and IO-idle each 60 seconds(you can change it) into a text file. hwgraphic (include in this project, writen in PHP) read the text file(generated by hwclient) and show the load-average chart and IO-idle chart.

This program builds up a Modem server, which supports Hiroyoshi Kurohara's NPCOMM-Suite.

Scbot is a C program that gives a remote control on a POSIX computer through reverse-shell on a chosen irc server channel. It is highly configurable and has a quite simple interface.

Telnetchatd is a chatserver which uses the telnetprotocol. Users do not need to install a client, as every desktop-OS comes with a preinstalled telnetclient. Programmed in pure C, the server needs very little resources and runs on any unix-like system.

vtwatch automatically switches the active virtual console on your Linux system in a loop, acting as a virtual terminal surveillance monitor. Includes switch-speed control, search strings, and more
