OOPS:vsftpd:cannot locate user specified in ' Ftp_username ': FTP

OOPS:vsftpd:cannot locate user specified in ' Ftp_username ': FTP

The error message. I googled a Google and found a mail that was very useful:
Http://lists.debian.org/debian-user/.../msg02648.html

One of the words mentioned:

Yep, I did. There is no occurrence to the string "tunable" anywhere in the vsftpd.conf man page ...

However, I ' ve been delving into the source code, and now understand This-the author The name of a config file uses tive *prefixed by* "Tunable_" inside the source code as a variable name. So what I needed to do is define "Ftp_username" in vsftpd.conf. For some reason of the Debian package leaves a little to is desired in this area, and neither asks you/want this dire The ctive set, nor creates, is the account, and VSFTPD anonymous connections. The default for this directive is the name "FTP", but there has never been a "ftp" account in my Woody system, nor. e created by the VSFTPD installation.

The author mentions receiving a oops but the tunable_ftp_username mentioned there is nowhere to be found. Later he looked at the source code, found that the source is using a "tunable_" as the prefix of the variable, in fact, the corresponding in the vsftpd.conf should be ftp_username this directive. So he added the ftp_username=xxx (user) line to the vsftpd.conf. But he also complained that the Debian distribution did not identify such issues anywhere. and the default user of this ftp_username should be FTP, but the woody system does not have this FTP user after the default installation, and VSFTPD installed did not add this user.

Note: I use Ftp_username=nobody, and then/etc/init.d/vsftpd restart after the successful landing.
