零、使用fping工具代替一、二

fping可以為多個IP地址生成ICMP分組，然後等待迴應，其執行速度要比下面的指令碼快得多。

http://www.fping.org/

fping選項說明：

　　-a顯示所有主機

　　-u顯示所有不可達的主機

　　-g指定IP地址範圍，格式為“IP地址/子網掩碼”或者“IP地址範圍”

　　2>/dev/null用於將主機不可達所產生的錯誤資訊輸出到null裝置

　　<FileName從檔案中傳遞一組IP地址

一、主機檢測命令ping

#!/bin/bash

#Description：The test script

red="\033[31m"
green="\033[32m"
shutdown="\033[0m"
read -p "請輸入你的ip地址:" ipadress
ping -W1 -c3 $ipadress &>/dev/null
if [ $? -eq 0 ];then
  echo -e "$ipadress is ${green}running${shutdown}......"
else
  echo -e "$ipadress is ${red}stopped${shutdown}......"
fi

二、24位掩碼區域網主機存活檢測

for ip in {1..254}
  do
    ping -w0.1 -W1 -c1 10.0.0.${ip} &>/dev/null
    if [ $? -eq 0 ];then
      echo -e "10.0.0.${ip} is ${green}running${shutdown}......"
    else
      echo -e "10.0.0.${ip} is ${red}stopped${shutdown}......"
    fi
done

三、埠檢測

#!/bin/bash
#****************************************************
#Date:        2020-06-25
#Author:      Damon Ye
#FileName：   PortLook.sh
#Description：The test script
#****************************************************
shutdown="\033[0m"
green="\033[32m"
blue="\033[34m"
for ip in {1..254}
 do
   ping -c1 -W1 -w0.1 10.0.0.${ip} &> /dev/null
   if [ $? -eq 0 ];then                                                                                                                                                                     
     echo -e "${green}#################################################${shutdown}"
     echo "Host 10.0.0.${ip} runs on the following ports. "
     nmap 10.0.0.$ip | sed -n '/^PORT/,/^MAC/p'| sed -n '/^[0-9]/p'
     echo -e "${blue}#################################################${shutdown}"
     echo -e "\n\n"
   fi
done
