FTP架设好了，可就是连不上，请大哥们帮忙看看是什么问题

linych

系统是debian，FTP用的是proftp，设置好了之后，就是登录上到FTP上，提示：
Connection   close  by remote host


查看系统端口，21是被proftp使用的

查看LOG：
proftpd[14587] localhost: ProFTPD killed (signal 15)
proftpd[14587] localhost: ProFTPD 1.3.0 standalone mode SHUTDOWN

不知道是什么原因被KILL

Yuri

1、启动的时候没有报错么？
2、是不是有selinux权限控制了？
3、还有你启动proftpd的用户是什么？
4、如果以上都没问题那请贴出配置文件和日志的上几行，仅提供两行不足以看出问题。

启动时没有报错

启动proftpd是ROOT启动的

selinux权限控制在哪里看？

刚刚试了登录，还是不行，看了一下LOG

Nov 28 17:43:43 hhuni proftpd[28688] localhost (x.x.x.x[x.x.x.x]): FTP session requested from unknown class
Nov 28 17:43:43 hhuni proftpd[28688] localhost (x.x.x.x[x.x.x.x]): FTP session closed.

其中LOCALHOST中的两个IP地址为同一个，是我本机的IP，不是服务器的

你是不是用的proftpd+mysql，如果是，请确认你的/etc/etc/proftpd下的modules.conf文件中的"LoadModule mod_sql_postgres.c"一行已经被注释掉，这是debian(或proftpd)的一个bug，我当初也是google了很久才解决的。

大哥，非常感谢！终于能访问了！
