1.批量测试主机连通性

#!/bin/bash
cat testsport   |  while read line
do
     curl -v --connect-timeout 15 $line > /dev/null 2>&1
     if [ $? -eq 0 ];then
         echo $line:ok
     else
         echo $line:fail
     fi
done

2.批量测试主机连通性ping IP

#!/bin/bash
# filename: /tmp/mydir/target_ip.txt
for ips in `cat /tmp/mydir/target_ip.txt`
do
        result=`ping -w 2 -c 3 ${ips} | grep packet | awk -F" " '{print $6}'| awk -F"%" '{print $1}'| awk -F' ' '{print $1}'`
        if [ $result -eq 0 ]; then
                echo ""${ips}" is ok !"
        else
                echo ""${ips}" is not connected ....."
        fi
done

3.批量测试主机连通性curl IP

#!/bin/bash
# filename: /tmp/target_ip.txt
for ips in `cat /tmp/target_ip.txt`
do
        echo ${ips}
        curl -v --connect-timeout 5 https://${ips} >> /tmp/curltest.txt 2>&1
        sed -n '$p' curltest.txt
done
