### 案例
ss -lntup | awk 'NR>1{gsub(/.*:/,"",$5);print "协议类型:" $1,"端口号:"$5}'
协议类型:udp 端口号:68
协议类型:udp 端口号:5355
协议类型:udp 端口号:19117
协议类型:udp 端口号:53
协议类型:udp 端口号:5355
协议类型:udp 端口号:5563
协议类型:tcp 端口号:5355
协议类型:tcp 端口号:22
协议类型:tcp 端口号:25
协议类型:tcp 端口号:5355
协议类型:tcp 端口号:8080
协议类型:tcp 端口号:80
协议类型:tcp 端口号:25
协议类型:tcp 端口号:8000
协议类型:tcp 端口号:8001
取出端口号并探测端口是否存活
