Requirement for Capture Tool
The following is the better, but not mandatory.
• Support GUI format (summary, details and dump).
• Enable to decode VoIP protocols.
Examples:
•Sniffer
• Ethereal
• Network Monitor for MS-Windows
• tcpdump (Linux, BSD)
• snoop (Solaris)
To analyze the captured data more efficiently, save the captured data in binary format (not text
format). The libcap format is better (suffix is .cap).
