简单shell实现局域网IP扫描
#!/bin/bash
network=$1
time=$(date +%H%M%S)
for i in $(seq $2 $3)
do
ping -c 1 -w 2 $network.$i > /dev/null
if [ $? -eq 0 ]; then
arp $network.$i | grep ":" | awk '{print $1,$3}' >> $time.log
echo "host $network.$i is up"
else
echo "host $network.$i is down"
fi
done
执行命令：
./netscan.sh 10.200.201 100 200
表示扫描10.200.201.100-10.200.201.200IP是否存活
