shell脚本批量测试TCP/UDP端口，通过telnet或者nc命令测试

tcp端口测试用telnet

#!/bin/bash

for line in `cat iplist.txt | grep -v ^# |grep -v ^$`
do  
    ip=`echo $line | awk 'BEGIN{FS="|"} {print $1}'`
    port=`echo $line | awk 'BEGIN{FS="|"} {print $2}'`
    echo "(sleep 1;) | telnet $ip $port"
    (sleep 1;) | telnet $ip $port > telnet_result.txt
    result=`cat telnet_result.txt | grep -B 1 \] | grep [0-9] | awk '{print $3}' | cut -d '.' -f 1,2,3,4`
    echo "$result"
    if [ -n "$result" ]; then
        echo "$result | $port" >> telnet_alive.txt
    else
        echo "*********************************************************************************************** $ip $port not pass"
     fi
done
cat iplist.txt telnet_alive.txt |sort|uniq -u| grep -v ^# > telnet_died.txt
echo "telnet is over"

udp端口测试用nc -vuz

#!/bin/bash

for line in `cat iplist.txt | grep -v ^# |grep -v ^$`
do  
    ip=`echo $line | awk 'BEGIN{FS="|"} {print $1}'`
    port=`echo $line | awk 'BEGIN{FS="|"} {print $2}'`
    echo "(sleep 1;) | nc -vuz $ip $port"
    (sleep 1;) | nc -vuz $ip $port > telnet_result.txt
done
echo "telnet is over"

这里的iplist.txt是在同级目录下面创建一个txt，内容如下，这里需要添加两个 |  ，因为windows的txt内的文字复制到linux环境下面，如果只用一个 | ，端口号获取有问题，用两个就没这问题。
