Open Source Network Monitoring Software

LCD Smartie displays information on your LCD/VFD. It supports LCDs with a Hitachi HD44780 Controller via parallel port & Matrix Orbital and Crystalfontz serial/USB LCD/VFDs. Info includes: CPU temps, fan speed, the BBC World News, Stocks indexes etc.

gtop is a tool that helps you monitor your systems through a dashboard user interface, and it is optimized to monitor and visualize terminals. gtop requirements are to have Node.js version 8 or higher. It supports Linux, OSX, and Windows (with partial support). You need to assign host net and pid to access the metrics in the host machine. Start gtop with the gtop command. To stop gtop use q, or ctrl+c in most shell environments. You can sort the process table by pressing 'p' for Process Id, 'c' for CPU usage, and 'm' for Memory usage. If you see question marks or other different characters, try to run it with the environment variables provided in the documentation. gtop is released under the MIT license.

tcp2com creates a bridge between a TCP socket and a serial port (COM). The program runs as a service under Windows NT. With tcp2com, you can telnet into any device you may have plugged into your COM port.

A VNC Client for J2ME (Java 2 Mobile Edition). This includes a side project, an easy to use, clean java API for the RFB protocall. This project is now dead. Please see: https://sourceforge.net/projects/j2mevncclient/

Console tool to live monitor (up to 15) hosts on a network. Written in C#, the tool is aimed to be simple and robust.

NetworkTools has 2 components: A protocol analyzer which plays a TCP client or server or pipeline, which sits between a client and server and shows how they communicate. A port scanner can scan a range of IP addresses and ports. See screenshots.

ProxyTerm (pterm) is a simple tool to control console applications running on a remote machine. Unlike in telnet/ssh, applications are not terminated if the connection is shut down, but are kept running for subsequent connections from pterm clients.

Control- and Status-Utility for Tr*ndCh*p-based ADSL-modems. It allows to access the devices' console-service and retrieves their current staus. For example those TC3084 devices are supported: Lucent CELL 19A-BX, Speed Modem 50B(+) and 200 by Arcor.

This is a cross platform tool to monitor traffic between two TCP endpoints. Allows to send users data to each endpoint, make data snapshots,manage multiple clients connections. Consists from forwarding server and client as stand along parts.

Mini OpenBSD Router/Firewall/Gateway with openssh, altqd, pfctl (firewall+nat), routed, snmpd, oidentd, simple shell menu config,multi user & wireless support. Fit on 8MB flashdisk & 24 MB ram.

This is studying project in CUFE intended to develop a temperature and security system based on a microcontroller with a serial communication with PC The Embedded software is developed on AVR Atmega16 microcontroller while the PC user interface is programmed with C# .Net 4.5 Project Description: https://goo.gl/KK9Aqc

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

Server that allow control windows remotly by console aplication with some features such as reduction of lag, reverse proxy and more.

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.

kcWebTelnet is a PHP Script that allows users to run Unix or Linux shell commands where TELNET is not provided from their web broswer.

perl-LCDd handles communication with an LCDproc v0.4 server. With this Perl library you avoid using raw sockets and the native LCDproc protocol.

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.

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
