使用此Shell脚本，您可以对远程主机执行ping操作，并检查是否在该服务器上打开了提到的端口。

这有助于系统管理员执行ping测试，并确保特定端口是否存在任何问题。

ping shell脚本

#!/bin/bash
if [ "$#" = "0" ];
then
echo "Usage: 
bobbin@theitroad:/$./script 127.0.0.1 22
Ping to host - OK, port 22 not opened.
desktop:~/$
 "
exit 1
fi
host=
port=
email="[email protected]"
subject="Script result"
if ping -q -c 4 $host >/dev/null
then
ping_result="OK"
else
ping_result="NOT OK"
fi
nc_result=`nc -z $host $port; echo $?`
if [ $nc_result != 0 ];
then
port_result="not opened"
else
port_result="opened"
fi
message="Ping to host - ${ping_result}, port $port ${port_result}."
if [ "$ping_result" != "OK" -o "$nc_result" != "0" ];
then
echo "$message"
echo "$message" | mail -s "$subject" $email
fi

脚本输出

ping to localhost并检查为22端口(SSH服务器)
