首先必须确定本地用户能登录，否则的话
#cp /usr/sbin/pure-ftpd-mysql /usr/sbin/pure-ftpd 。
使用mysql的root帐号比较方便，所以是
grant all privileges on FTP.* to localhost identified by '123456'
最后PureFTP User Management能使用的话而虚拟用户不能使用的话就是pureftpd的设置问题了，注意ftp根目录和ftp用户的所属关系。
必须在系统里面建立一个名为ftp的用户，当然也要把/etc/pure-ftpd/conf/NoAnonymous 改为no。
我是这个做的：useradd ftp -g ftpgroup -d /yourftpdir -s /etc

在哪里能找到免费的域名
forum.prayaya.com中这个forum代表什么，怎么能实现
vsftpd的3种登陆方式：

Working at shell prompt is an essential task for any Linux system administration. However many newcomers find it difficult to work at bash prompt. Here are some tricks to speed up your work.

(A) Shortcut keys for command editing:
CTRL+L : Clear the screen

CTRL+R : To search for a command in command history. For example yesterday or few hourse back you typed 'a very very long command' and you need same command again. Then hit CTRL+R and type first few letters of command.

CTRL+C : Cancel command

CTRL+Z : Suspend command

CTRL+T : transpose characters. For example by misspelled command date:
＄ daet
Sure you can rub the last two character and retype it again, but wait just hist CTRL+T and you are done:
＄ daet [CTRL+T]
Result into character transpose:
＄ date

ALT+T OR ESC+T: transpose words. For example you typed:
＄ filename rm
To correct it just hit ALT+T
＄ filename rm [ALT+T]
And you have correct command to remove a file.
＄ rm filename

CTRL+U : Deletes entire line

CTRL+K : Deletes to end of line from current cursor position

HOME OR CTRL+A : Moves cursor to beginning of line

END OR CTRL+E : Moves cursor to end of line

(B)Recall last argument from previous command – to save time
ALT+. (hold down ALT key and press period/dot)
For example first you typed the mkdir command as follows:
＄ mkdir -p /tmp/demo/software/qtapp
Now you would like change directory to /tmp/demo/software/qtapp, then type cd and press ALT+.:
＄ cd [PRESS alt+.]

(C) Command completion
Most of the Linux admin uses TAB key to complete command names and files names. So let us say you would like to mount something then:
i) Type word mo:
＄ mo
ii) Hit TAB key to complete word
＄ mo [TAB]
iii) And end result should be:
＄ mount

(D) List the possible completions
BASH also supports the possible completions of commands or text (file). For example you would like to list all the possible command starts with ls command:
＄ ls [ESC]
Will display following text (above the current command line)

ls lsmod lsmod.modutils lspci lsusblsattr lsmod.Lmodutils lsof

Next time I will discuss more about advanced command line completions and other cool features.
