Proftpd : Allow users to see root

Question

I am setting up an FTP server and initially jailed all users in their home directory by using:

DefaultRoot ~

This behaviour causes the users to see only the contents of their home directories and nothing above it. For ex : When using a client such as filezilla and user as testuser, the testuser directory shows up as

/
incoming/
outgoing/

However I want to see if theres any way to allow users to 'see' the directories above it but not allowing them to list its contents, creating, deleting any files or directories . So using filezilla for testuser would be like:

/ftp
/home/
testuser/
incoming/
outgoing/

The only reason being is that currently we have automated pipelines that use the full path to get files i.e. /ftp/home/testuser/dir/file.txt which fails on my current config . However /dir/file.txt works just fine.

Any help will be greatly appreciated

Answer 1

The best approach: adjust the automated pipelines. (of course..)

Another really simple (but still silly) one: create a relative symlink within the home, that should also work.

Ex:

mkdir -p /ftp/home/testuser/ftp/home
cd /ftp/home/testuser/ftp/home
ln -s ../../ testuser
ls -l /ftp/home/testuser/ftp/home/testuser
#lrwxrwxrwx 1 testuser testuser 15 Oct  6 16:37 testuser -> ../../
ls -l /ftp/home/testuser/ftp/home/testuser/dir/file.txt
#-rw-rw-r-- 1 testuser testuser 16 Nov  6 16:37 file.txt
