It would appear that both mmcache and eaccelerator complain when setup under a suphp implementation for PHP and apache. Seems like most people recommend using fastcgi+suexec and then a php accelerator, but I’m uncertain how that will turn out as of right now. Another option on a per user basis would be to use Alternative PHP Cache (APC )
The problem arises when a user attempts to make an anonymous FTP connection to Cpanel user’s account who has already enabled anonymous FTP connections in their control panel. However, pure-ftpd drops you with the error “421 Can’t change directory to /var/ftp/”.
workstation:~ user$ ftp testing.com Connected to testing.com. 220---------- Welcome to Pure-FTPd [privsep] [TLS] ---------- 220-You are user number 3 of 50 allowed. 220-Local time is now 11:02. Server port: 21. 220-IPv6 connections are also welcome on this server. 220 You will be disconnected after 15 minutes of inactivity. Name (testing.com:user): anonymous 421 Can't change directory to /var/ftp/ [/] ftp: Login failed.
The solution(s):
1. Use anonymous@domain.com and any password instead of just anonymous
…OR
2. Assign the Cpanel user a dedicated IP address where FTP logins with just “anonymous” will work.
