linux 批量telnet脚本

1、创建sh脚本

vi telnet_batch.sh

#!/bin/bash

check_telnet(){
for ip_port in $(cat ip_info|grep -v '^#')
do
CHECK_PORT=$(echo $ip_port|awk -F: '{print $2}')
CHECK_IP=$(echo $ip_port|awk -F: '{print $1}')
echo -e "\n"| telnet $CHECK_IP $CHECK_PORT |grep "Connected to\|Escape character" >/dev/null
if [ $? -eq 0 ];then
echo "$LOCALIP result $CHECK_IP $CHECK_PORT connected"
else
echo "$LOCALIP result $CHECK_IP $CHECK_PORT can not Connected"
fi
done
}
check_telnet >result.log

chmod +x telnet_batch.sh

 

2、创建ip_info文件，输入要telnet的IP地址+端口：

vi ip_info

10.10.10.10:80
10.10.10.10:8080
10.10.10.11:80
10.10.10.11:8080

3、执行脚本，结果输出到result.log文件

sh telnet_batch.sh

cat result.log
