我使用Nmap在我的metasploitable机器上扫描了来自Kali的开放端口,并使用Wireshark捕获了流量,并注意到对于发送到开放端口的每个SYN数据包,也发送了一个RST数据包。为什么?
答案 0 :(得分:1)
阅读RFC 793 3.4,以了解有关重置数据包的更多信息。您的情况是:
1. If the connection does not exist (CLOSED) then a reset is sent in response to any incoming segment except another reset. In particular, SYNs addressed to a non-existent connection are rejected by this means.
