Hello everyone,

I need as much feedback as possible, so please feel free to comment.

I am in the process of currently selecting a protocol analyzer/protocol decoder (aka sniffer), whether it is commercial or open source.

I am very curious to here everyone’s insight on what product they choose and why?

What criteria did you use to make your final decision?

Cost and operating system is not one of my requirements. The sniffer can run on any platform whether it is Windows or Linux.

I look forward to hearing back from everyone.

Thanks in advance,

Take care,

ethereal everytime, cos it's great. midn you a sniffer is just a tool to help you out. not necessarily the sort of thing that always needs much commitment, especially with somethign like ethereal.

The only thing I know of is tcpdump and ethereal.

tcpdump because almost all linux OS have it. Ethereal because it do everything.

If it's not to much trouble, could you list *your* criteria?

I use Ethereal for protocol/traffic analysis and NMap for doing port sniffing. As to why I chose them - they're open source and in Ethereal's case, it runs on both Linux and Windows.
