What does Analyzer?

Analyzer is not a simple network sniffer. Here there is a brief summary of what it can do.

Network Sniffer
Analyzer can capture (and display) packets on both the local machine and remote probes, thanks to the full support of the Remote Capture functionality of WinPcap.
Additionally, one of the most valuable point is the ability to parse network packets according to the protocol description contained in external files, which can be modified at run-time by the user. These files are written in the new NetPDL language; for who is interested in that, please read the Protocol Dissectors Section.
Advanced sniffing capabilities
Due to the full support of the WinPcap remote capture capabilities, Analyzer is able to display packets currently being captured on another (remote) host. This can be done even if the remote host is behind a firewall, thanks to the support of the Active Mode remote capture. Additionally, Analyzer supports also sampling in order to reduce the amount of traffic generated by the remote host toward Analyzer. Sampling is available also when capturing from a local interface.
End-to-end Reachability Monitor
Analyzer can monitor the reachability (through a set of ICMP ECHO, aka PING, packets) of remote host, saving data into a database and making additional statistics. The user can later retrieve historical data to see how the reachability of some host changed over time.
Additionally the user can set some alarm (e.g. "send an e-mail") in case of some event (e.g. "host down").
Local Network Host Monitor
Analyzer can discover the presence of the active station on your local network and display their MAC, IPv4 and IPv6 addresses, and their canonical name.
This module can monitor the availability of the stations and signal whether an host is up, is down, and so on. Furthermore, it can detect address spoofing (e.g. when the same IPv4/IPv6 address appears to bind more than one MAC addresses).
Additionally the user can set some alarm (e.g. "send an e-mail") in case of some event (e.g. "possible spoofing").
Network Sessions Logger
Analyzer can monitor the presence of TCP/UDP/ICMP "sessions" over the network, saving a database record for each session detected within a time frame. A summary of the session is then saved into a database for later processing.
Network Data Mining
Analyzer is able to apply Data Mining techniques to the database of the sessions, created with the Network Sessions Logger (NetLogger). This module is able to find some relevant relationships over the data which may be unexpected and it is able to give an insight about how the network looks like (e.g. which are the servers, which are the clients, and more). Furthermore, it can compare the relationships that come out from two different NetLogger databases and display the differences (e.g. a new server has been added to the network).
Event Handling
Analyzer has a module that manages events associated to the other modules and it executes the appropriate actions. The number of events and the actions associated to them are customizable by the user.

WARNINGS

  • Analyzer is a tool that is still under development. Please be patient when you use it.
  • Analyzer could not work with earlier versions of Windows 95
  • Analyzer does not work in Windows CE
  • Some features could not be supported on all platforms

Analyzer Roadmap

The first step is to get the WinPcap 3.1 out. As soon as this library will be released, we will release a beta version of Analyzer.

A 3.0 final version of Analyzer should came in September 2005.

The 3.0 release will provide a first, affordable tool. For instance, a lot of users are pushing for getting the 3.0 final out, even if some of our objectives (in terms of functionalities) are not reached. Refinements are expected in the next minor releases.

Aaronia Spectrum Analyzer

Usually, a spectrum analyzer displays a power spectrum over a given frequency range, changing the display as the properties of the signal change. There is a trade-off between how quickly the display can be updated and the frequency resolution, which is for example relevant for distinguishing frequency components that are close together. With a digital spectrum analyzer, the frequency resolution is Δν = 1 / T, the inverse of the time T over which the waveform is measured and Fourier transformed. With an analog spectrum analyzer, it is dependent on the bandwidth setting of the bandpass filter. However, an analog spectrum analyzer will not produce meaningful results if the filter bandwidth (in Hz) is smaller than the square root of the sweep speed (in Hz/s), which means that an analog spectrum analyzer can never beat a digital one in terms of frequency resolution for a given acquisition time. Choosing a wider bandpass filter will improve the signal-to-noise ratio at the expense of a decreased frequency resolution.

With Fourier transform analysis in a digital spectrum analyzer, it is necessary to sample the input signal with a sampling frequency νs that is at least twice the highest frequency that is present in the signal, due to the Nyquist limit. A Fourier transform will then produce a spectrum containing all frequencies from zero to νs / 2. This can place considerable demands on the required analog-to-digital converter and processing power for the Fourier transform. Often, one is only interested in a narrow frequency range, for example between 88 and 108 MHz, which would require at least a sampling frequency of 216 MHz, not counting the low-pass anti-aliasing filter. In such cases, it can be more economic to first use a superheterodyne receiver to transform the signal to a lower range, such as 8 to 28 MHz, and then sample the signal at 56 MHz. This is how an analog-digital-hybrid spectrum analyzer works.

For use with very weak signals, a pre-amplifier can be used, although harmonic and intermodulation distortion may lead to the creation of new frequency components that were not present in the original signal. A new method, without using a high local oscillator (LO) (that usually produces a high-frequency signal close to the signal) is used on the latest analyzer generation like Aaronia´s Spectran series. The advantage of this new method is a very low noise floor near the physical thermal noise limit of -174 dBm.
