I'm experimenting with Samba shares at home and I'm trying to understand how symbolic links work.
I have a few network shares on a couple of machines that run a mix of Windows and Ubuntu or Debian distros.
I'm trying to understand a few things:
is it possible to allow for the creation of symbolic links (from any client) inside the shares and across shares but not outside shared paths? For example if I have
/srv/share2would it be possible to link:
/srv/share1/link -> /srv/share1/file
/srv/share2/link -> /srv/share1/file
but not any file outside these 2 directories?
is it possible to make symlinks "transparent" on any client or specific clients when mounting the shares? Are there specific options I should use when mounting them on other machines to see links as such?
Right now mounting them using
cifsshows symlinks as it was a normal files (I didn't set any options using the command beside authentication).
This answer: Deleting Ubuntu folder symlink deletes target folder's contents when done via OSX & Samba seems to support this behaviour.
I'd like to get a clearer understanding on which are the pros and cons of various options used to manage links; in particular which are the advantages and disadvantages of:
[global] allow insecure wide links = Yes unix extensions = Yes wide links = Yes
[global] unix extensions = No # Does this imply UNIX clients cannot create symlinks? wide links = Yes
besides the obvious security problem related to
allow insecure wide linksbeing turned on.
The above config is from: https://unix.stackexchange.com/q/5120/181086
A partial answer is given here: creating symbolic links on networked drive but it's related to Windows.
Other answers such as: Ubuntu + latest samba version, symlinks no longer work on share mounted in windows
Creating a Symlink in an NTFS share
aren't really recent and don't go in-depth in the reasons why it does or doesn't work.
Finally this one I didn't understand Samba Linux shares -- Why won't windows machines display/follow symbolic links?.
