在SL6 x86_64上托pipeproftpd时，我有一个有趣的问题。 从源代码编译时，proftpd可执行文件将忽略HideGroupfunction。 但是，当我通过rpm安装epel的旧版本时，这个HideGroupfunction工作得很好。 为什么从source / tar安装mod_core的这个特性会被忽略，但是在从epel / rpm安装的时候会得到这个特性呢？
我在“/ var / ftp /”中有一个名为“pictures”的目录，我不希望它对匿名用户可见。 所以我有隐藏组中的隐藏，但它被忽略！ 任何想法为什么？ 这里有一些debugging信息。

而当我在非守护程序详细模式下运行proftpd时，吐出这个：

当我运行指向相同的/usr/local/etc/proftpd.conf的proftpd（从epel通过rpm（yum）安装），事情工作得很好！
任何想法，我忽略了这个问题？
什么：
$ proftpd -V
显示通过rpm（yum）从epel安装的proftpd ？ 上述命令发出的事情之一是用于该proftpd二进制文件的编译时选项列表。 通过比较你的configure命令选项和epel版本的configure命令选项，你可能会发现罪魁祸首。
