目录

Wireshark 根底 | 闪现过滤篇

简介

「Wireshark 闪现过滤」(display filter),即通过过滤选择,需要闪现哪些特定的数据包。

作用

闪现过滤器容许将注意力会合在感兴趣ht测试仪tpclient的数据包上,一同躲藏当前不感兴趣的数据包。

容许只闪现数据包根据:

  • 协议
  • 字段是否存在
  • 字段值
  • 字段间的比较

言语

闪现过滤器言语由 Wireshark 本身供应chrome安卓下载,通过不nginx怎么读windows许可证行将过期怎样办同的过滤表达式可以可以精确chrome浏览器无法上网地操控闪现哪些chrome安卓版数据包。nginx负载均衡

建议

学习资源详见windows7旗舰版官方文档,包含 Wiki DisplayFilters 和 Display Filters 语法Wind测试你适合学心理学吗ows

语法

过滤器表达式

[not] primitive [and|or [not] primitive ...]

过滤器表达式由一个或多个原语组成

[x] x为nginx面试题可选
x|y 选x或测试抑郁程度的问卷y
<x> x为必选检验用例
xyz xyz为关键字,必需
and(&&)、or(||)、not(!) 代表与、或、非

原语格式chrome什么意思

格式

Protocol[.string1.string2...stringN] [Comparison operator] [Value]

protocchrome浏览器ol

eth、ip、arp、tcp、udp 等。

支撑的协议,nginx面试题View → Intnginx配置ernals → Supported Protocolswindows7怎么重装系统

string

addr、port、flags、flags.syn、len 等。

示例

eth.addr == ff:ff:ff:ff:ff:ff
tcp.port == 80
tcp.flags
tcp.flags.syn == 1
ip.len <= 60
...

comparison operator检验用例

eq(==)、ne(!=)、gt(>)、lt(<)、ge(>=)、le(<=)、contains、matches(~)、bitiwise_and(&)

示例

ip.src == 10.0.0.5
ip.src != 10.0.0.5
frame.len > 10
frame.len < 128
frame.len ge 0x100
frame.len <= 0x20
udp contains 81:60:03
http.host matches "ace.(org|com|net)"
tcp.flags & 0x02
...

!= 注意事项

ip.addr == 1.2.3.4,闪现全部包含 IP 地址 1.2.3.4 的数据包
ip.addr != 1.2.3.4,闪现全部不包含 IP 地址 1.2.3.4 的数据包?语法差错!关于源或目的 IP 地址为 1.2.3.4 的包,该表达式也适用。因为 ip.addr != 1.2.3.4 表达式被理解为 “the packet contains a field named ip.addr with a value different from 1.2.3.4” 。IP 数据包包含源和目的 IP 地址,当两个地址中至少有一个与 1.2.3.4 不一同,表达式的值将为 true 。
!(ip.addr == 1.2.3.4),闪现全部不包含 I P地址 1.2.3.4 的数据包

版别 3.6.0 之后“a != b”现已完全等同于“!nginx启动命令(a == b)”。

value

Unsigned integer 可以为 8,16,24http://192.168.1.1登录,32 或 64httpwatch bit 。 十进制、八进制或十六进制表明整数。

示例

ip.len le 1500
ip.len le 02734
ip.len le 0x5dc

Signed intchttp://www.baidu.comhrome安卓版eger 可以为8,16,24,32或64 bit。 十进制、八进制或十六进制表明整数。

B检验郁闷程度的问卷oolean 1(真)或 0(假)

不管值是真仍是假,布尔值字段都httpwatch会出现检验英文

比如 tcp.flags.syn ,syn 存在于全部包http代理含该标志的 TCP 数据包中,不管 syn 标志是 0 仍是https和http的区别 1 。nginx怎样读

示例

tcp.flags.syn == 1

Ethernet address 6 字节,经ngi测试用例nx装备过 :,. ,或者 – 分隔。

chrome什么意思

eth.dst == ff:ff:ff:ff:ff:ff
eth.dst == ff-ff-ff-ff-ff-ff
eth.dst == ffff.ffff.ffff

IPv4 address检验郁闷程度的问卷 示例

ip.addr == 192.168.0.1
ip.addr == 10.1.0.0/16

IPv6 address 示例

ipv6.addr == ::1
ipv6.addr == 2400:640:100:100::/64

Text stwindows是什么意思ring 示例

http.request.uri == "https://www.wireshark.org/"

联合表达式

ahttp 404nd(&&)

L检验工程师ogical AND

示例

ip.src==10.0.0.1 and tcp.flags.fin

or(||)

Logical OR

示例chrome

ip.scr==10.0.0.1 or ip.src==192.168.1.1

xor(^^)

Logical XOR

http 404

tr.dst[0:3] == 0.6.29 xor tr.src[0:3] == 0.6.29

eth.src[1-2] == 00:83
第二到第三个字节为 00:83 的以太网源 mac 地址
eth.src[:4] == 00:00:83:00

eth.src[4:] == 20:20
最终两个字节以 20:20 结束的以太网源 mac 地址
eth.src[2] == 83
第 3 个字节为 83 的以太网源 mac 地址
eth.src[0:3,1-2,:4,4:,2] == 00:00:83:00:83:00:00:83:00:20:20:83
复合规划
  • Slice Operator,Wireshark 容chrome许选择序列的子序列,在标签之后可以放置一对方括号 [],其间包含逗号分隔的规chrowindows怎么激活me模说明符列表。

  • 指定单个规划的格式:

nhttp://www.baidu.com:m,n 是初步偏移量,m 是指定的规windows是什么意思划的长度;
n-m,chrome什么意思http 500n 是初步偏移量,m 是结束偏移量;
:m,等同于 0:m ,windows许可证即将过期怎么办从一个序列的初步偏移 m ;
n:,从偏移量 n 到序列的结Nginx束;
n,等同于 n:1 ,从偏移量windows是什么意思 n 初步chrome浏览http 302器安卓版下载检验工程师移 1 。

  • Wireshark 容许将单个规windows更新有必要吗模串在windows10逗号分隔的列表中,构成复合规划。

in

Set Membershipwindows更新有必要吗

示例

tcp.port in {80 443 8080}
tcp 源或目的端口为 80、 443 或 8080 的数据包,等同于 tcp.port == 80 || tcp.port == 443 || tcp.port == 8080
tcp.port in {443 4430..4434}
不等同于 tcp.port == 443 || (tcp.port >= 4430 && tcp.port <= 4434)
因为当任意字段匹配过滤器时都满足比较运算符,所以源端口为 56789 ,目的端口为 80 的数据包也会匹配第二个过滤器,因为 56789 >= 4430 && 80 <= 4434为真。
http.request.method in {"HEAD" "GET"}
ip.addr in {10.0.0.1..10.0.0.9 192.168.1.1..192.168.1.9}
frame.time_delta in {0.001 .. 0.002}
...
  • Membership Opernginx负载均衡ator,Wireshark 容许检验字段在一组值或字段中的成员联络。在字windows是什么意思段名之后检验你的自卑程度,运用 in 操作符,后跟大括号windows11有必要升级吗 {} 围住的调集项。
  • 当任意字段匹配过滤器时都满足比较运算符。
  • 成员资格操检验郁闷程http 500度的问卷作符根据规划条件检验你的自卑程度检验单个字段。
  • 调集项不只限于数字nginx重启,其他类型也可以运用。

函数nginx服务器

闪现过滤器言语有许多转化字段的函数。

upper

将字符串字段转化为大写。

lChromeower

将字符串字段转化为小写。

示例

lower(http.server) contains "apache"
upper 和 lower 函数可以用来强制不差异大小写的匹配

len

回来字符串或字节字段的字节长度。

示例

len(http.request.uri) > 100
查找具有长恳求 uri 的 HTTP 恳求
len(ip.addr) == 4
len 函数生成的字符串长度是以字节为单位

count

回来在一个nginx负载均衡帧中出现字段的数目。

示例检验用例Nginx

count(ip.addr) > 2
一般一个IP帧只要两个地址(源和目的),但是在 ICMP 差错或地道的情况下,单个数据包或许包含更多的地址。

stringchrome什么意思

将非字符串字段转nginx反向代理化为字nginx启动命令符串。测试你适合学心理学吗

示例

string(frame.number) matches "[13579]$"
匹配奇数帧序号
string(ip.dst) matches "^172.(1[6-9]|2[0-9]|3[0-1])..{1,3}.255"
匹配以 255 结束的 172.16-172.31 子网里的目的 IP
...
  • string 函数将字段值转化为字符串,适用于操作符“matches”或“contains”。
  • 整数字段http 404被转化为十进制表明。
  • 可以用于 IP/以太网地址(以及其他nginx反向代理地址),但不能用于字符串或字节字段。
