Getting this error message trying to start vsFTPd on FreeBSD?
500 OOPS: vsftpd: not configured for standalone, must be started from inetd
Then you missed the important part shown at the end of “vsftpd.conf”!
# If using vsftpd in standalone mode, uncomment the next two lines: listen=YES background=YES
Just uncomment “listen=YES”, “background=YES” and start the daemon again :
/usr/local/libexec/vsftpd /usr/local/etc/vsftpd.conf
