OOPS:vsftpd:refusing to run with writable root inside Chroot ()

Ubuntu 12.04 64bit system installed under the VSFTPD, when logged in prompted by OOPS:vsftpd:refusing to run with writable root inside Chroot (). The root cause is that, starting with version vsftpd_2.3.5, the writable permissions for the roots are canceled. Therefore, the general solution on the Internet is the following two kinds of solutions:

方案一

$ chmod a-w /vaf/ftp

方案二

$ vim /etc/vsftpd.conf add the following

allow_writeable_chroot=YES

It seems that the second way is more perfect, but when I put the Allow_writeable_chroot=yes configuration item, when I restart the VSFTPD service found that it does not work properly (21-Port no program in the monitoring), so the Internet to find solutions, found a variety of statements , some people say that the configuration item is allow_writable_chroot (less e), and that the configuration item is allow_writable_root (less ch), etc., after I test, found that all is not working. Finally, a workable method was found.

Complete solution for Ubuntu 12.04 64bit

$ apt-get install python-software-properties

$ sudo add-apt-repository ppa:thefrontiergroup/vsftpd

$ sudo apt-get update

$ sudo apt-get install vsftpd

$ vim /etc/vsftpd.conf and add the following

chroot_local_user=YES

allow_writeable_chroot=YES

$ sudo service vsftpd restart
