在Mac OS X 10.6上的特权端口(端口< 1024)上进行绑定 [英] Binding on privileged ports (ports < 1024) on Mac OS X 10.6

问题描述

您知道如何取消对端口绑定的限制吗?使用不是Mac OS X根用户的用户帐户显示1024?

Do you know how to remove restriction on binding to ports < 1024 with a user account that is not root on Mac OS X?

推荐答案

最好的方法是利用launchd.与端口绑定的限制< 1024仍将存在，并且不可能随处可见，但是如果您的应用一次请求提升的特权才能添加必要的启动配置，则可以让launchd在特权端口上进行实际侦听并将套接字传递给您的应用在适当的时候.

The best way is to leverage launchd. The restriction on binding to ports < 1024 will still be there and is not likely to go anywhere, but if your app requests elevated privileges once in order to add the necessary launchd configuration, then you can let launchd do the actual listening on the privileged port and pass the socket to your app when appropriate.
