proftpd给出“登录错误”错误

Question

我安装proftpd已经有一段时间了，但是从今天起我就不能登录ftp服务器了。我一直得到错误的530 login incorrect。

我在调试模式下重新启动了proftpd，并在尝试登录时获得了以下响应：

Answer 1

听起来你安装的libpam在proftpd时还没有升级，可能会在对proftpd进行升级之前尝试这样做，看看这是否纠正了问题。

还特别检查了proftpd.conf

#这是使用基于PAM的身份验证和本地密码#AuthOrder mod_auth_pam.c* mod_auth_unix.c所必需的。

^并确保conf没有更新为“泛型”。

Answer 2

有一点要注意的是.pam_shells.so

pam_shells.so --这要求所有允许的shell位于/etc/shell中。

对于NIS，因为我们有许多不同的Linux和Solaris发行版，所以我们的NIS shell都是/usr/local/bin/

在机器本身上，我们在/usr/local/bin/中创建到shell的软链接。即/usr/local/bin/bash -> /bin/bash

我被烧伤的地方是..。即使/bin/bash在/etc/shell中，/usr/local/bin/bash也需要在其中。

这是一个10秒的修正，但我花了很长时间才弄清楚。

Answer 3

还要确保主目录实际上是由该用户拥有的。例如，我只是尝试ftp到用户abc，但是/home/abc是根用户拥有的，而不是abc，所以proftpd给了我不正确的登录。
