Exporting a file through NFS

[Samshen]

Hi,
I want to know, is it possible to export a single file through NFS instead of a whole directory?

Thank you.

Never thought about that, but I assume it is always based on directories, so you need to export an directory.

Hi Sam,

Exporting a single file wouldn't be possible,You need to export a complete directory

Sounds right to me.

You could create a new directory, and put
into it (only) a hard link to the file of
interest. (That might work until someone
replaces that file in its original location.)

Shalom,

You can do it.

1) Make the file the only file in a directory.
2) Make the file permissions on the other files 000 so they are invisible.
3) Work with ownership and make the other files member of a group that can not be seen.

Definitely possible. You just can't do it by simply adding an entry to /etc/exports or /etc/dfs/dfstab and running exportfs

It is more work than that.

Any particular problem you are trying to solve by only exporting one file? Security?

Steven's hardlink suggestion seems the best solution. Make sure you create that directory on the same filesystem as the original file.
