Init is one of the most indispensable programs in Linux system operation. Init process, which is a user-level process initiated by the kernel. The kernel will find it in several places in the past that used Init, and its correct location (for Linux systems) is/sbin/init. If the kernel cannot find Init, it will try to run/bin/sh, and if it fails, the boot of the system will fail.Linux 7 RunLevel (0: shutdown, shutdown mode,

Seturlstreamhandlerfactory () method on the URL with an instance of Fsurlstreamhandlerfactory. This method can be called only once per JVM, so it is typically executed in a static block.The HDFs URL scheme that allows Java to identify Hadoop also requires a bit of extra work, which can be done here by invoking the Seturlstreamhandlerfactory () method in the URL of the Fsurlstreamhandlerfactory object. This method can only be executed once per JVM, so it is usually executed in a static block.d)

From this, we can see that NMAP scans the port 80 of the other party and then uses a large number of scripts starting with HTTP to scan it. The scanning process found that in the HTTP-auth script execution, the words "Basic relm = TP-LINK wireless n router wr740" appeared (red line part ), the type and version of the target device have been mined.
