Zenmap

Managing network computers and tracking traffic, connections and other related tasks are something administrators or power users with advanced knowledge in this field are expected to do. However, with the help of some powerful utilities, the like of Zenmap, you can view some information which might interest you.

Featuring a user friendly interface and with all the commands easily accessible, this program makes network monitoring a quiet easygoing job. Zenmap can display various data concerning hosts and services and all you have to do is browse to the corresponding tab in the main window.

Thus, you can checkout the ports for the selected host and see their number, protocol, state ('open' or 'closed'), service in use and version. Zenmap is also able to draw the network topology, starting from the chosen host.

You can opt for the 'Hosts Viewer' with its actions and views or pick the 'Fisheye' mode for a different approach. If you want to view some details concerning the selected server, Zenmap shows the current status, open, filtered, closed and scanned ports, Ipv4 and Ipv6 addresses, hostnames, operating system it is running and a lot more.

The program has several profiles you can choose from, depending on the type of scan you want to perform. It also supports direct commands and you will be able to customize the existing profiles or create ones of your own.

Designed to work with large networks and provide quick scans, Zenmap is not difficult to use and will work just as well on smaller LANs or single hosts. With its strong feature pack, the software is one of the best choices one can make when it comes to this type of applications.
