※ 引述《pttnews (PTT新聞)》之銘言：
: Tomcat 安裝時會預設開一個shutdown port
: 請問這是幹啥麼用？ 會不會有資安問題？
: 要怎麼disable?
: 謝謝！

=====================================================================
http://tomcat.apache.org/tomcat-7.0-doc/config/server.html
The TCP/IP port number on which this server
waits for a shutdown command.
Set to -1 to disable the shutdown port.
Note: Disabling the shutdown port works well
when Tomcat is started using Apache Commons Daemon
(running as a service on Windows or with jsvc on un*xes).
It cannot be used when running Tomcat with
the standard shell scripts though,
as it will prevent shutdown.bat|.sh and catalina.bat|.sh
from stopping it gracefully.
