Вот эта тема не помогла - proftpd не хочет работать через service в centos 5.5

Снес proftpd и proftpd.conf, поставил proftpd заново, всеравно не могу зайти по фтп.

Я ни фига не сисадмин и сломал уже всю голову себе, что делать?

Trying 127.0.0.1...
Connected to localhost (127.0.0.1).
220 FTP Server ready.
Name (localhost:root): webbold
331 Password required for webbold
Password:
530 Login incorrect.
Login failed.
Remote system type is UNIX.
Using binary mode to transfer files.

Вот конфиг дефолтный, только PAM закомментил, но и сним то же самое:
