terminal - 格式化 tshark 输出

Question

现在我正在使用

tshark -i wlan0 -c 10 -T fields -e ip.src -e ip.dst -e ip.proto -e tcp.srcport -e tcp.dstport -e udp.srcport -e udp.dstport > test.txt

它工作正常，它给了我这样的输出:

192.168.1.240   198.38.110.157  6       50735   80              198.38.110.157  192.168.1.240   6       80      50735           192.168.1.240   198.38.110.157  6       50735   80              198.38.110.157  192.168.1.240   6       80      50735           192.168.1.240   198.38.110.157  6       50735   80              198.38.110.157  192.168.1.240   6       80      50735           192.168.1.240   198.38.110.157  6       50735   80              198.38.110.157  192.168.1.240   6       80      50735           192.168.1.240   198.38.110.157  6       50735   80              198.38.110.157  192.168.1.240   6       80      50735 

非常酷，但是有没有人能够为每个协议(protocol)提供一个像这样的简单堆栈？只是一个简单的制表符分隔字段，我似乎无法在 tshark 手册页中找到此选项。

您可以尝试使用tshark的-o选项来格式化tshark的输出。

例如，

tshark.exe -o "gui.column.format:\"Source\",\"%us\",\"Destination\",\"%ud\",\"src port\",\"%S\",\"dest port\",\"%D\"" -r sample_001.cap.pcapng

结果:

10.191.144.161 → 10.210.62.164 57434 8888
10.191.144.161 → 10.210.62.164 57434 8888
10.210.62.164 → 10.191.144.161 8888 57434

(然后，你只需要把“→”去掉即可)

要查看可选择的输出字段的完整列表，请使用命令tshark.exe -G column-formats:

c:\Program Files\Wireshark>tshark.exe -G column-formats
%q      802.1Q VLAN id
%Yt     Absolute date, as YYYY-MM-DD, and time
%YDOYt  Absolute date, as YYYY/DOY, and time
%At     Absolute time
%V      Cisco VSAN
%B      Cumulative Bytes
%Cus    Custom
%y      DCE/RPC call (cn_call_id / dg_seqnum)
%Tt     Delta time

%L      Packet length (bytes)
%p      Protocol
%Rt     Relative time
%s      Source address
%S      Source port
%rs     Src addr (resolved)
%us     Src addr (unresolved)
%rS     Src port (resolved)
%uS     Src port (unresolved)
%E      TEI
%Yut    UTC date, as YYYY-MM-DD, and time
%YDOYut UTC date, as YYYY/DOY, and time
%Aut    UTC time

例如，使用 tshark 打印 Wireshark 的默认列:

tshark.exe -o "gui.column.format:\"No.\",\"%m\",\"Time\",\"%t\",\"Source\",\"%s\",\"Destination\",\"%d\",\"Protocol\",\"%p\",\"Length\",\"%L\",\"Info\",\"%i\""
