Editor to share with you how to deal with VSFTPD experiment 500OOPS errors, I believe that most people do not know much, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Vsftpd has been used for a year, found a VSFTPD error, has been reporting an error, searched the Internet, there is an explanation.

Debugging information: 500OOPS: vsftpd: refusing to run with writable anonymous root

Cause: vsftpd does not allow "dangerous (unsafe)" configurations. This error message is usually caused by incorrect ownership and permissions of ftp's home directory and its subdirectories.

Namely: anon_root=/var/ftp:FTP's home

The owner of the home directory should not be the ftp user himself, and the ftp user cannot have write permission. The solution is:

Chown root ~ ftp; chmod-w ~ ftp

For example, anon_root=/var/ftp is set in the configuration file

Achieve the following results:

This is what happens in / var/ftp:

Ls-ld ftp

Drwxr-xr-x 4 root root 4096 12 21 19:35 ftp # here is the owner and group are root, the default permission755, write permission is removed

[root@ftp ftp] # ls-l

Drwxrwxr-x 2 ftp ftp 4096 12 21 20:08 incoming # subdirectory owner and group are ftp, and permission is related to the purpose of the directory. Because I have to write.

Drwxr-xr-x 2 root ftp 4096 12 21 19:36 pub # here the read-only directory owner is root, the group is ftp, the default is permission755, and write permissions are removed.
