pingIP的脚本和nc端口的脚本

初级ping脚本 

for i in `cat /root/ip.txt`
        do
        ping=`ping -c 3 $i > /dev/null`
 if [ $? -ne 0 ];then
 echo "ping $i fail" >> /root/fail.txt
 else
 echo "ping $i ok" >> /root/ok.txt
 fi
 done
 
 编写放IP的文档 ip.txt
 
 
 # 速度慢
ZB-FTP-Server01:~/python # cat ping.sh 
#!/bin/bash
for ip in `cat /root/python/ip.txt`
	do 
		ping -c 1 $ip |grep -q 'ttl=' && echo $ip ok || echo $ip failed
	done
	
	
 # 速度快
 ZB-FTP-Server01:~/python # cat p2.sh 
#!/bin/bash
>ping.log
for ip in `cat /root/ip3.txt`
	do 
	    nohup	ping -c 1 $ip |grep -q 'ttl=' && echo $ip ok || echo $ip failed  >> ping.log  &
	done

初级nc端口脚本：

#!/bin/bash
for i in `cat ip.txt`
	do
	#nc -v -w 1 $i 3389
	nc -zw1 $i 3389
	if [ $? -eq 0 ]
	then
		echo "$i        3389 is ok !" >> ./result_
