我们学过TCP协议,知道TCP三次握手中的第一次生成的seq是随机生成的,接下来的数据的seq都是在首seq的基础上递增的,但是我们在收到数据后进行逻辑处理的时候,为了方便后续开发,我们引出了三个概念:初始序列号(initial sequence number)、相对序列号(relative sequence number)绝对序列号(absolute sequence number) 初始...
In a communication between the host and computer in which one of them acts as a source and the other as a destination for the communication, a sequence number offset is derived by the firewall which characterizes the byte sequence number received from the source and the byte sequence number ...
tcpprobe显示的是TCP栈那里的情景,而tcpdump抓取的确实网卡边界的情景,中间隔了一个“qdisc”逻辑,即队列管理。也就是说TCP确实将732个数据段发出去了,因此它会认为其已经in flight了,但是这些数据并没有到达网上,而是到达了qdisc队列里面,考虑到是千兆网络同一网段的模拟,基本可以忽略传输延迟,因此tcpdump抓取的所谓...
How to Do TCP Sequence Number Analysis May10 19 But more importantly, WHY you should do TCP sequence number analysis. Well, you know all those black and red packets in Wireshark? Sure, you’ve seen them, right? Scary, huh? What if someone says there’s a problem and you see a bunch...

因为ESP认为,上层应该会更早的感知链路出来问题。如TCP会自行发现。有交互的UDP,应用层也会发现。 这里的re-synchronization机制只针对一种情况,就是udp单侧发包,对方无回应的应用场景。 写到这里。。突然发现后边的内容理解的不是很好。。。就先这样了。。。 到底...

In this study, we discover a new class of unknown side channels —“sequence-number-dependent” host packet counters — that exist in Linux/Android and BSD/Mac OS to enable TCP sequence number inference attacks. It allows a piece of unprivileged on-device malwa...
