Tcpdump error and warning messages are sent to stdout. This causes issues when the packet capture is sent to a file, and standard programs such as Wireshark do not understand the error message strings and error.
Captures cannot be analyzed from the capture file
-- tcpdump used to capture packets. -- tcpdump stdout redirected to a file. -- The capture file is read by standard packet parse-and-display tools wuch as Wireshark .
None.
Tcpdump messages are now sent to stderr. Packet dumps continue to be in stdout. A capture file contains only captured packets, and can be analyzed by any tool that understands pcap format (wuch as Wireshark, tshark etc.)
