Allows Mac OS X clients (10.3.3 or above) to automagically establish a tunneled AFP connection through SSH. If this option is set, the server’s answers to client’s FPGetSrvrInfo requests contain an additional entry. It depends on both client’s settings and a correctly configured and running sshd(8) on the server to let things work.
Note
Setting this option is not recommended since globally encrypting AFP connections via SSH will increase the server’s load significantly. On the other hand, Apple’s client side implementation of this feature in MacOS X versions prior to 10.3.4 contained a security flaw.
第三步:接上图,我在设置共享的时候,出现“Internet 连接共享访问被启用时,出现了一个错误。(null) ”这样的错误提示,经过查询得知这是由于未开启 Windows Firewall 服务造成的,只需右击我的电脑–管理–服务和应用程序–服务,然后在右边找到 Windows Firewall 双击打开,如下图,将启动类型设置为自动即可(如仍未启动,需手动启动一下),然后再回头去做第二步就可以了。(如果还是不行,请检查 Internet Connection Sharing(ICS)、Wired AutoConfig、Wireless AutoConfig 这三个服务是否都已经启动)
