How to add NTFS volume with NTFS-3G and use it for VSFTPD

Postby chandranjoy » Thu Nov 03, 2011 5:29 am

I have seen several blogs and forum entries elsewhere state that because NTFS volumes do not support linux ownership or permissions, they cannot be used for anonymous ftp upload through the vsftpd program.

IT can be done and here's how to get it working:

In this example, I have an external NTFS Gigabyte drive that I called "Store01". This volume contains a directory called "/ftp". Anonymous ftp clients should be able to upload to what is seen thru FTP as "/ftp/pub", and I want these files to actually show up in /ftp on my external NTFS drive.

The first requirement is that vsftpd wants the anonymous root directory to be owned by ftp:ftp

You'll need to find the right id so look in the user file to find the id for ftp. In this case:
Code: Select all
cat /etc/passwd


Again, in this case my system ftp is userid 14

Next look in the groups file to find the id for the ftp group:

Code: Select all
cat /etc/group


In this example, the ftp group is 50

Next, look to see what device name my NTFS volume has:
Code: Select all
fdisk -l


On my system, my NTFS volume is shown to be called: /dev/sdc1

Now create a mount point for it thus (I'm arbitrarily calling it "Store01":

Code: Select all
mkdir /mnt/Store01


in /etc/fstab, this line gets the NTFS volume mounted at /mnt/Store01:

Code: Select all
/dev/sdc1    /mnt/Store01    ntfs-3g    nls=utf8,auto,user,rw,uid=14,gid=50,umask=0000,defaults 0 0


Note that it is going to belong to user 14, which is ftp on my system, and group 50, which is ftp on my system. VSFTPD requires that anonymous upload directories to belong to ftp:ftp

Now define a mount point you want to use as your ftp anonymous root:
Code: Select all
mkdir /var/ftp
chown root:root /var/ftp
mkdir /var/ftp/pub
chown ftp:ftp /var/ftp/pub


Notice /var/ftp is owned by root:root, and therefore cannot be written to by vsftpd. This is a requirement of vsftpd for a ROOT anonymous directory, that the anonymous root directory not be writable. So, /var/ftp is what I'm going to use as the anonymous root directory.
But /var/ftp/pub is writeable by vsftpd. It appears to anonymous users as a "pub" directory on the FTP site where they can write files.

So add this line to /etc/fstab, which will point /var/ftp/pub (the anonymous writable directory) to the /ftp folder on my NTFS volume:
Code: Select all
/mnt/Store01/ftp    /var/ftp/pub    auto    bind 0 0


And finally, in /etc/vsftpd/vsftpd.conf, this line:
Code: Select all
anon_root=/var/ftp


Now an anonymous user can upload into the "pub" directory, on the anonymous FTP site. Files uploaded there will appear in /ftp on my NTFS volume.
