Top 4 Free Network Analysis Software
Here are 4 of the best free tools for monitoring devices, services, ports or protocols and analyzing traffic on your network.
1. OpenNMS
OpenNMS also includes a client app for the iPhone, iPad or iPod Touch for on-the-go access, giving you the ability to view outages, nodes, alarms and add an interface to monitor.
Once you successfully login to the OpenNMS web UI, you can get more information about any of these sections from the Status drop down menu. The Reports section allows you to generate reports to send by e-mail or download as a PDF.
OpenNMS is an open source enterprise grade network management application that offers automated discovery, event and notification management, performance measurement, and service assurance features.
2. Advanced IP Scanner
Advanced IP Scanner tool is an easy and fast to use network scanner that detects any network devices (including wireless devices ) on your network.
The installer allows you to fully install the application on your machine or run the portable version.
You can choose which subnet to scan and proceed with pressing the “Scan” button. Once the scan is complete, expand the results to see which resources you are able to connect to for each discovered device.
3. Microsoft Network Monitor
Microsoft Network Monitor is a very useful packet analyzer that allows you to capture, view and analyze network traffic.
Main features include support for over 300 public and Microsoft proprietary protocols, simultaneous capture sessions, a Wireless Monitor Mode and sniffing of promiscuous mode traffic, amongst others.
This tool is handy for troubleshooting network problems and applications on the network.
4. NetworkMiner
NetworkMiner captures network packets and then parses the data to extract files and images, helping you to reconstruct events that a user has taken on the network – it can also do this by parsing a pre-captured PCAP file.
You can enter keywords which will be highlighted as network packets are being captured. NetworkMiner is classed as a Network Forensic Analysis Tool (NFAT) that can obtain information such as hostname, operating system and open ports from hosts.
