首先查看捕获帧长度的问题,增加 Capture Length列,对比可知在 No.7、No.9 和 No.10 均存在捕获长度小于实际帧长度的地方,并且有两个值,54 和 59 ,确实如 capinfos 的提示信息一样,Packet size limit: inferred: 54 bytes - 59 bytes (range) ,此处初步判断是人为编辑过数据包跟踪文件。 image.png 其次...

使用tcpdump进行抓包,然后用wireshark进行分析的时候,出现了”Packet size limited during capture”,也不算是错误,只是数据包里的内容无法完全查看清楚: 经过查询,原因是因为我在Linux下进行抓包的时候没有设定截取包的长度,于是tcpdump默认采用了长度为68或96字节来进行抓包,导致一些数据稍多的包内容显示不全面。 只...
TCP协议中还规定,发送者要先把原始的数据分割成以“包”(Packet) 为单位的数据单元,然后再发送,而接收者要把收到的包拼装在一起还原出原始数据。 三、协议分层 每一层间的逻辑通信都需要一组地址(源地址和目标地址),这个地址在每一层的名字: 应用层:名称如baidu.com 传输层:端口号 网络层:IP地址 数据链路...
So there is a need for me to limit the write size to a value we find can give the best responsive experience for the client. Right now there is no way to avoid the re-adjustment of write size. I see something is not right. Can you share the Wireshark Packet Capture file (.pcap)...

Linux autotuning is logic in the Linux kernel that adjusts the buffer size limits and the receive window based on actual packet processing. It takes into consideration a number of things including TCP session RTT, L7 read rates, and the amount of available host memory. ...
