vsftpd - "553 could not create file"

Question

I'm having issue with my vsftpd.

here is my info:

# cat /etc/redhat-release

I'm trying to utilize virtual users feature inside of vsftpd and while authentication part works without any issues, unfortunately write doesn't work.

# ls -ld /var/www/html/
drwxr-xr-x. 5 root root 71 Jun 14 13:45 /var/www/html/
# ls -ld /var/www/html/test/
drwxrwxr-x. 2 apache apache 30 Jun 14 14:45 /var/www/html/test/
# cd /etc/

I've tried to disabling(permissive) and enabling(enforcing) SELinux and still same undesirable result(

What am I missing?

Answer 1

I'm not sure why (perhaps a bug?), even though nopriv_user was set to apache, somehow vsftpd was thinking it set to ftp:

# grep ^nopriv_user vsftpd.conf
nopriv_user=apache
#

... yet when I upload file it's like nopriv_user is set to ftp:

# ls -ld test test/13924501638_26bbdf9023_o.jpg
drwxrwxr-x. 2 apache ftp      41 Jun 17 13:01 test
-rw-r--r--. 1 ftp    ftp 2885458 Jun 17 13:01 test/13924501638_26bbdf9023_o.jpg
# 

So, unless I'm doing something wrong, maybe I should submit it to vsftpd as bug.

Maybe because dir. owner is root and you're trying to write as test user
