Summary
This review was originally posted on VersionTracker.com.<br />I find this app interesting and quite useful. It allows you to see the raw data that's being transmitting via your TCP/IP connection. I don't know much about what alot the data means... but I like to check that, when I use certain TCP/IP apps, the data (such as logins & passwords) are not being transmitted in plain text. Also, it's interesting to see the background noise that seems to be transmitted, from your computer, related to cookies, and what-not. I've never seen anything similar to it. I'd give it 5-stars if it had a "Help" section, or a manual, for better understanding of things. (And, the "Save" function doesn't seem to work).
Great app, though CPU usage goes out of sight

Summary
This review was originally posted on VersionTracker.com.<br />Eavesdrop is great- does what it says and provides an eye-opening look at how much your Mac is constantly communicating in the background without your knowledge. Also amazing to see how unsecure most of your communications really are. Only glitch is that once Eavesdrop begins a capture, CPU usage goes to around 85% on my G4 iMac with 768 megs of ram! You have to quit Eavesdrop to regain your CPU- stopping capture alone is not sufficient.
Outstanding

Developer’s Description

network capture & analysis of TCP conversations

Eavesdrop is a network capture application (based on tcpdump) that captures and understands TCP conversations. It keeps track of the TCP flag history and extracts the payload of each conversation as it is captured. The payload is also searched for image data to display. Graphs can be created to view trends in the captured data.
