Function Description: Dump the network transmission data.
Grammar: tcpdump&http://www.aliyun.com/zixun/aggregation/37954.html ">NBSP;" [-ADEFLNNOPQSTVX] Number of [-c< Packets [-DD] [-DDD] [-f< Express Document [-i< Network Interface [-r< Packet File [-s< Packet Size [-tt] [-t< Packet Type [VV] [-w< Packet File [Output data field]
Supplemental Note: Execute tcpdump instructions to list the header of a packet file that has been assigned a network interface, and you must be a system administrator in the Linux operating system.
Parameters: -a attempts to convert network and broadcast addresses to names. -c< Number of packets > The number of packets received, the dumping operation stopped. -D converts the compiled packet encoding into a readable format and dumps it to standard output. -DD converts the compiled packet code into a C language format and dumps it to standard output. -DDD converts the compiled packet encoding into a decimal number format and dumps it to the standard output. -e Displays the header of the connection level on each column dumping data. -F Displays the Internet address in digital. -f< Express File > Specify a file containing the expression. -i< network interface > send packets using the specified network section. -L uses a buffer of the standard output column. -N does not convert the host's network address to a name. -N does not list domain names. -O does not optimize packet encoding. -P does not allow the network interface to enter promiscuous mode. -Q Fast output, listing only a handful of transport protocol information. -r< packet files > reads packet data from a specified file. -s< Packet Size > Set the size of each packet. -S lists the number of TCP associations with absolute rather than relative values. -T displays a time stamp on each column dumping data. -TT displays unformatted timestamp on each column of dumping data. -t< Packet Type > forces the packets specified by the expression to be translated into the set packet type. -V details the instruction execution process. VV Displays the instruction execution process in more detail. -X lists the packet data in hexadecimal codes. -w< packet File > writes packet data to the specified file.
