shell腳本批量測試TCP/UDP端口，通過telnet或者nc命令測試

tcp端口測試用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端口測試用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"

這裏的iplist.txt是在同級目錄下面創建一個txt，內容如下，這裏需要添加兩個 |  ，因爲windows的txt內的文字複製到linux環境下面，如果只用一個 | ，端口號獲取有問題，用兩個就沒這問題。
