goproxy的socks5代理和ssh -D的socks5代理响应不一样

[han0x7300]

用goproxy建立socks5代理： ./proxy sps -p "0.0.0.0:1080" 通过proxychains4+nmap扫描主机上关闭的端口，会有响应。nmap 显示 PORT STATE SERVICE VERSION 8081/tcp open tcpwrapped 用ssh -D建立socks5代理，通过proxychains4+nmap扫描关闭的端口，则是正确的显示端口关闭 PORT STATE SERVICE VERSION 8081/tcp closed blackice-icecap 扫描命令： proxychains4 nmap -sT -PN -n -sV -p 8081 192.168.111.129 proxychains4 配置： socks5 127.0.0.1 1080

结果就是导致nmap扫描出的全是开放的端口，非常不准确。

备注：8081端口上没有服务。
