Illegal to add users and illegal to enter the remote operation of users!

01. Illegal User Intrusion System

The simplest way is to check with the W command.

If an illegal user is confirmed to be present within the system, the user-related process can be immediately kill.

kill-9 ' Lsof-u xxx ' # # #杀掉非法用户所启动的进程
userdel-r XXX # # #删除非法用户xxx及其主目录

1. First use the W command to view the user's TTY number, then use the
skill-kill-t pts/1(or display pts/*) #踢出用户-kill can be replaced with signal-9

2. Or first use the W command to view the online users, and then:
pkill-kill-t TTY #如pkill-kill-t PTS/1
