Linux下批量ping某个网段ip的脚本

 

好比如今须要对172.16.50.0/24网段的ip进行检查，检查哪些ip如今被占用，哪些ip没有被占用，能够经过ping命令来检查，脚本以下:

[root@uatdns01 opt]# vim /opt/ping.sh 
#!/bin/bash
. /etc/init.d/functions
for var in {1..254};
do
ip=172.16.50.$var
ping -c2 $ip >/dev/null 2>&1
if [ $? = 0 ];then
action "$ip" /bin/true
else
action "$ip" /bin/false
fi
done

[root@uatdns01 opt]# chmod 755 /opt/ping.sh
[root@uatdns01 opt]# sh /opt/ping.sh

172.16.50.105                                            [  OK  ]

172.16.50.112                                            [  OK  ]

                                                                                                                                                                         

获取172.16.60.0/24网段可用ip的shell脚本
[root@ansible-server ~]# cat ip_ping.sh 
#!/bin/bash 
ip=1 
while [ $ip != "254" ]; do 
ping 172.16.60.$ip -c 2 | grep -q "ttl=" && echo "172.16.60.$ip yes" || echo "172.16.60.$ip no" 
ip=`expr "$ip" "+" "1"` 
done 

执行:
[root@ansible-server ~]# sh ip_ping.sh
172.16.60.1 yes
172.16.60.2 no
172.16.60.3 no
.............
172.16.60.24 yes
172.16.60.25 yes
172.16.60.26 no
.............

若是只打印可用ip, 则脚本修改以下:
[root@ansible-server ~]# cat ip_ping.sh
#!/bin/bash 
ip=1 
while [ $ip != "254" ]; do 
ping 172.16.60.$ip -c 2 | grep -q "ttl=" && echo "172.16.60.$ip yes" || echo "172.16.60.$ip no" >/dev/null 2>&1
ip=`expr "$ip" "+" "1"` 
done 

执行:
[root@ansible-server ~]# sh ip_ping.sh
172.16.60.1 yes
172.16.60.21 yes
172.16.60.22 yes
172.16.60.23 yes
172.16.60.24 yes
172.16.60.25 yes
172.16.60.31 yes

ping 172.16.50.$ip -c 2 | grep -q "ttl=" && echo "172.16.50.$ip yes" || echo "172.16.50.$ip no" >/dev/null 2>&1
ip=`expr "$ip" "+" "1"` 

ping 172.16.51.$ip -c 2 | grep -q "ttl=" && echo "172.16.51.$ip yes" || echo "172.16.51.$ip no" >/dev/null 2>&1
ip=`expr "$ip" "+" "1"`
