本仓库用来收集tshark User Guide、tshark常用命令以及tshark常用 lua 脚本。
1. 数据包合并:把后两个数据包并到一个数据包merge.pcap
mergecap -w merge.pcap 1.pcap 2.pcap
2. 按照ssl/http 条件过滤数据包
tshark -r 1.pcap -Y [ssl|http] -w ssl.pcap
tshark -2R ssl -r toutiao.pcap -w ssl.pcap
-2: 执行两次分析
-R: -R <read filter>,包的读取过滤器，可以在wireshark的filter语法上查看；在wireshark的视图->过滤器视图，在这一栏点击表达式，就会列出来对所有协议的支持。
3. 分割数据包: 按照数据包数分割一个大的数据
editcap -c 1000000 merge.pcap split01.pcap
4. tshark -X lua_script:cutflow.lua -r wireshark.pcap
5. tshark -q -X lua_script:cutflow.lua -r wireshark.pcap
二.具体使用案例
1.抓取500个包,提取访问的网址打印出来
tshark -s 0 -i eth0 -n -f 'tcp dst port 80' -R 'http.host and http.request.uri' -T fields -e http.host -e http.request.uri -l -c 50
2.抓取500个包,提取访问者访问地址及提交方式和访问者ip
tshark -s 0 -i eth0 -n -f 'tcp dst port 80' -R 'http.host and http.request.uri' -T fields -e frame.time -e ip.src -e http.request.method -e http.host -e http.request.uri -e ip.src -e ip.dst -l -c 500
3.抓取mysql的查询
tshark -i eth1 -d tcp.port==3306,mysql -T fields -e mysql.query 'port 3306'
tshark -i lo -d tcp.port==3306,mysql -T fields -e mysql.query 'port 3306'
指定类型
tshark -i lo -d tcp.port==3306,mysql -T fields -e mysql.query 'port 3306' -R 'mysql matches "SELECT|INSERT|DELETE|UPDATE"'
4.统计http状态
tshark -n -q -z http,stat, -z http,tree

TShark (Wireshark) 2.4.2 (v2.4.2-0-gb6c63ae)
Dump and analyze network traffic.
See https://www.wireshark.org for more information.
Usage: tshark [options] ...
Capture interface:
-i <interface> name or idx of interface (def: first non-loopback)
-f <capture filter> packet filter in libpcap filter syntax
-s <snaplen> packet snapshot length (def: appropriate maximum)
-p don't capture in promiscuous mode
-I capture in monitor mode, if available
-B <buffer size> size of kernel buffer (def: 2MB)
-y <link type> link layer type (def: first appropriate)
-D print list of interfaces and exit
-L print list of link-layer types of iface and exit
Capture stop conditions:
-c <packet count> stop after n packets (def: infinite)
-a <autostop cond.> ... duration:NUM - stop after NUM seconds
filesize:NUM - stop this file after NUM KB
files:NUM - stop after NUM files
Capture output:
-b <ringbuffer opt.> ... duration:NUM - switch to next file after NUM secs
filesize:NUM - switch to next file after NUM KB
files:NUM - ringbuffer: replace after NUM files
Input file:
-r <infile> set the filename to read from (- to read from stdin)
Processing:
-2 perform a two-pass analysis
-M <packet count> perform session auto reset
-R <read filter> packet Read filter in Wireshark display filter syntax
(requires -2)
-Y <display filter> packet displaY filter in Wireshark display filter
syntax
-n disable all name resolutions (def: all enabled)
-N <name resolve flags> enable specific name resolution(s): "mnNtCd"
-d <layer_type>==<selector>,<decode_as_protocol> ...
"Decode As", see the man page for details
Example: tcp.port==8888,http
-H <hosts file> read a list of entries from a hosts file, which will
then be written to a capture file. (Implies -W n)
--enable-protocol <proto_name>
enable dissection of proto_name
--disable-protocol <proto_name>
disable dissection of proto_name
--enable-heuristic <short_name>
enable dissection of heuristic protocol
--disable-heuristic <short_name>
disable dissection of heuristic protocol
Output:
-w <outfile|-> write packets to a pcap-format file named "outfile"
(or to the standard output for "-")
-C <config profile> start with specified configuration profile
-F <output file type> set the output file type, default is pcapng
an empty "-F" option will list the file types
-V add output of packet tree (Packet Details)
-O <protocols> Only show packet details of these protocols, comma
separated
-P print packet summary even when writing to a file
-S <separator> the line separator to print between packets
-x add output of hex and ASCII dump (Packet Bytes)
-T pdml|ps|psml|json|jsonraw|ek|tabs|text|fields|?
format of text output (def: text)
-j <protocolfilter> protocols layers filter if -T ek|pdml|json selected
(e.g. "ip ip.flags text", filter does not expand child
nodes, unless child is specified also in the filter)
-J <protocolfilter> top level protocol filter if -T ek|pdml|json selected
(e.g. "http tcp", filter which expands all child nodes)
-e <field> field to print if -Tfields selected (e.g. tcp.port,
_ws.col.Info)
this option can be repeated to print multiple fields
-E<fieldsoption>=<value> set options for output when -Tfields selected:
bom=y|n print a UTF-8 BOM
header=y|n switch headers on and off
separator=/t|/s|<char> select tab, space, printable character as separator
occurrence=f|l|a print first, last or all occurrences of each field
aggregator=,|/s|<char> select comma, space, printable character as
aggregator
quote=d|s|n select double, single, no quotes for values
-t a|ad|d|dd|e|r|u|ud|? output format of time stamps (def: r: rel. to first)
-u s|hms output format of seconds (def: s: seconds)
-l flush standard output after each packet
-q be more quiet on stdout (e.g. when using statistics)
-Q only log true errors to stderr (quieter than -q)
-g enable group read access on the output file(s)
-W n Save extra information in the file, if supported.
n = write network address resolution information
-X <key>:<value> eXtension options, see the man page for details
-U tap_name PDUs export mode, see the man page for details
-z <statistics> various statistics, see the man page for details
--capture-comment <comment>
add a capture comment to the newly created
output file (only for pcapng)
--export-objects <protocol>,<destdir> save exported objects for a protocol to
a directory named "destdir"
Miscellaneous:
-h display this help and exit
-v display version info and exit
-o <name>:<value> ... override preference setting
-K <keytab> keytab file to use for kerberos decryption
-G [report] dump one of several available reports and exit
default report="fields"
use "-G ?" for more help
