Capture traffic

tshark有capture filter和display filter。display filter跟wireshark的一样，使用-Y指示，导出到文件时(-w)，该指示不能使用; capture filter使用-f指示; -O 'tcp,quic' 显示协议详情。

# display filter
tshark -o "tls.keylog_file: $PWD/keylog.txt" -i lo -Px -O quic -Y "udp.port == 4434"

# 使用capture filter过滤，导出15个packets到文件tshark.log, 里面依然包括QUIC协议展开
# 导出文件tshark.log可以导入到wireshark中查看
tshark -o "tls.keylog_file: $PWD/keylog.txt" -i lo -Px -O quic -f "udp port 4433" -w tshark.log -a packets:15
