which is computer software or computer hardware that can intercept and log traffic passing over a digital network or part of a network.[1] As data streams flow across the network, the sniffer captures each packet and eventually decodes and analyzes its content according to the appropriate RFC or other specifications.

Uses

The versatility of packet sniffers means they can be used to:

* Analyze network problems
* Detect network intrusion attempts
* Gain information for effecting a network intrusion
* Monitor network usage
* Gather and report network statistics
* Filter suspect content from network traffic
* Spy on other network users and collect sensitive information such as passwords (depending on any content encryption methods which may be in use)
* Reverse engineer proprietary protocols used over the network
* Debug client/server communications
* Debug

3) If the radio passes those tests, then I’d say you’re OK to put the rest of the tubes in and power the entire radio up in stages.”
