- Packets `received by filter' (the meaning of this depends on the OS on which you're running tcpdump, and possibly on the way the OS was configured - if a filter was specified on the com-mand command line, on some OSes it counts packets regardless of whether they were matched by the filter expression and, even if they were matched by the filter.
- Tcpdump filter to match DHCP packets including a specific Client MAC Address: tcpdump -i br0 -vvv -s 1500 '((port 67 or port 68) and (udp38:4 = 0x3e0ccf08))' tcpdump filter to capture packets sent by the client (DISCOVER, REQUEST, INFORM): tcpdump -i br0 -vvv -s 1500 '((port 67 or port 68).
WinDump is the Windows version of tcpdump, the command line network analyzer for UNIX. WinDump is fully compatible with tcpdump and can be used to watch, diagnose and save to disk network traffic according to various complex rules. It can run under Windows 95, 98, ME, NT, 2000, XP, 2003 and Vista.
Mar 01, 2020 Tcpdump will, if not run with the -c flag, continue capturing packets until it's interrupted by a SIGINT signal (generated, for example, by typing your interrupt character, typically Ctrl+C) or a SIGTERM signal (typically generated with the kill(1) command); if run with the -c flag, it will capture packets until it is interrupted by a SIGINT or SIGTERM signal or the specified number of packets. The -D flag will not be supported if tcpdump was built with an older version of libpcap that lacks the pcapfindalldevs(3PCAP) function.e Print the link-level header on each dump line. This can be used, for example, to print MAC layer addresses for protocols such as Ethernet and IEEE 802.11.
WinDump captures using the WinPcap library and drivers, which are freely downloadable from the WinPcap.org website. WinDump supports 802.11b/g wireless capture and troubleshooting through the Riverbed AirPcap adapter.
