1.以":"作为分隔符，将IP及port信息贴入ip_port_info文件中，第一列为IP，第二列为端口
192.168.233.155:2337
192.168.233.155:2338
192.168.233.155:2339
192.168.233.136:3015
192.168.233.155:3022
192.168.233.136:3299
192.168.233.136:4000
2.脚本内容
#!/bin/bash
>temp_file
>check_result
echo "ip port result" >> check_result
cat ip_port_info |while read line
do
ip=$(echo "${line}" |awk -F ":" '{print $1}')
port=$(echo "${line}" |awk -F ":" '{print $2}')
ssh -o ConnectTimeout=10 -o BatchMode=yes -o StrictHostKeyChecking=no -p ${port} test@${ip} >> temp_file 2>&1
value=$(cat temp_file |tail -n 1 |grep -E 'Connection timed out during|gssapi-with-mic' |wc -l)
echo ${value}
if [ ${value} -eq 1 ]
then
echo "${ip} ${port} true" >> check_result
else
echo "${ip} ${port} false" >> check_result
fi
echo "" >temp_file
done
3.使用方法
nohup sh check_port.sh &即可
4.输出结果
ip port result
192.168.233.155 2337 true
192.168.233.155 2338 true
192.168.233.155 2339 true
192.168.233.136 3015 false
192.168.233.155 3022 false
192.168.233.136 3299 true
192.168.233.136 4000 true
