Nmap Security Scanner

Nmap ("Network Mapper") is a free open source utility for network exploration or security auditing. It was designed to rapidly scan large networks, although it works fine against single hosts. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what ... [More] services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. Nmap runs on most types of computers and both console and graphical versions are available. [Less]

check_mk

Check_mk adopts a new a approach for collecting data from operating systems and network components. It obsoletes NRPE, check_by_ssh, NSClient and check_snmp. It has many benefits, the most important of which are: * Significant reduction of CPU usage on the Nagios host. * Automatic inventory of ... [More] items to be checked on hosts. The larger your Nagios installation is, the more important get these points. In fact check_mk enables you to implement a monitoring environment exceeding 20.000 checks/min on the first hand. [Less]

Yong

Yong is server/network/uptime monitor that is completely independent of server side software , this means that you did not need to run anything on your target server , Yong independently check target server for icmp echo request , dns hostname request , and any tcp based protocol via hot-plugable mechanism .

Very Simple Network Scanner

Big brother (the other one)

Big Brother is the simplest tool for monitoring IP-network for troubles. It gives a comprehensive picture of what happened to any point on the Net that has been put in.

pomamonitor

Introductionpomamonitor (Poor's Man Monitor) is a shell script that rely's on notify-send command to send alerts to Gnome/KDE/XFCE desktop user when a host or several hosts that was previously set to be monitored are offline. Pretty useful for small system administrators that doesn't ... [More] need Nagios/Zabbix for monitoring such a small enviroment. Obviously, it supports IPv6: we are in 2009! Why Poor's Man?A system administrator usually needs to monitor constantly the machines and system he is responsible for. This is often done by central monitoring systems, with several nodes like Nagios, Zabbix or Cacti. But this would require a central server to keep track of all uptime/downtime data, server's info like load average etc. A poor man (a ironic way to refer to a modest sysadmin) wouldn't have a central server to do such thing or even not too many hosts to care about. So the objective with this project is just to give a quick desktop alert to sysadmins that something is wrong with a server or network. Quick alerts can lead to quick responses and less downtime. Useful ApplicationsJohn has many websites hosted in different datacenters. He wants to be alerted if any of his websites go down to jump on the tech support's neck as soon as possible. Mike is responsible to monitor several VPNs with dynamic IPs and domestic broadbands. He wants to know if xpto.no-ip.org stopped responding to act as quickly as he can. Mark is an IRC administrator of a network that is a constant target of DDoS. He needs to be warned if a server stopped responding even if he is not using an IRC client at the moment. Kurt is some sort of wierd telecom geek that wants to measure and monitor absolutely everything on internet to warn his friends over twitter when a famous service is offline. Software Dependencies and TechnologyYou will find what are pomamonitor's software dependencies and how does it work under the hood on SoftwareDependencies page. I'm impatient: how do I run it?So, want to download the latest pomamonitor version? Just read HowToInstall page. Help neededWe don't need to be Obama to say 'Yes we can!'.
