Formatting tshark output

Question

Right now I'm using

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

Which is working okay it gives me an output like:

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 

Pretty cool, but is there anyone to get a nice simple stack like this for EVERY protocol? Just a simple tab delimited field I cannot seem to find this option in the tshark man page.

Answer 1

You can try to use the -o option of tshark to format the output of tshark.

For instance,

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

result:

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

(then, you just need to remove the "→")

To view the complete list of output fields that you can select, use the command tshark.exe -G column-formats:

c:\Program Files\Wireshark>tshark.exe -G column-formats

%Yut    UTC date, as YYYY-MM-DD, and time

For example, to print Wireshark's default columns with tshark:

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