Open Source Linux Network Monitoring Software

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.

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.
