I have a usb drive attached to my Pi3 with vfat filesystem. I've mounted it in fstab and assigned a uid and gid. I am using pfoftpd to allow storage of files and allow directories to be created. I have several users like user1, user2, etc. I can ssh in and create directories with any of these users. However using ftp I can only create a directory with whichever user I make as uid in fstab. The gid seems to make no difference, no other user can create a directory on this vfat usb. Is there a way to make the entire group be able to create directories, they all can upload files to that directory for some reason though.
Here is my fs tab:
proc /proc proc defaults 0 0
/dev/mmcblk0p6 /boot vfat defaults 0 2
/dev/mmcblk0p7 / ext4 defaults,noatime 0 1
# a swapfile is not a swap partition, no line here
# use dphys-swapfile swap[on|off] for that
/dev/sda1 /media/usbhdd vfat auto,nofail,noatime,users,umask=000,uid=camera,gid=ftpusb 0 0
Here are my users that are relevant:
proftpd:x:112:65534::/run/proftpd:/bin/false
ftp:x:113:65534::/srv/ftp:/bin/false
amcrest:x:1001:1001:,,,:/home/amcrest:/bin/bash
userftp:x:1002:1002::/home/FTP-shared:/bin/false
camera:x:1003:1003::/media/usbhdd/cam1:/bin/bash
cam1:x:1004:1005:cam1,,,:/media/usbhdd/cam1:/bin/bash
dnsmasq:x:114:65534:dnsmasq,,,:/var/lib/misc:/bin/false
Here is my permissions for the usb drive:
drwxrwxrwx 2 camera ftpusb 16384 Dec 16 2015 System Volume Information
drwxrwxrwx 2 camera ftpusb 16384 Oct 21 09:14 test1
