From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

How to transfer files over network preserving the xattrs? (self.linux)

Title.

The situation is basically this:

NFS works, it's very fast, keeps the xattrs but if used without Kerberos it's not secure. If used with Kerberos it works, but has a ticket that expires and forces me to reenter the credentials frequently in order to use it. If there was a way to use NFS with Kerberos and save the credentials NFS would be the perfect solution.
Samba works fine too, also keeps the xattrs but I had some troubles with filenames (mainly with some special characters, emoji, etc). Besides, as both my server and my clients run Linux I prefer to avoid it if I have the choice.
sshfs would be the natural choice, not as fast as NFS but it's pretty secure, I already use it in most of my network shares but I just can't find a way to make it preserve the files xattrs.

Do you guys have any suggestions or maybe any other options that I might use?

Sure. I have a little home server running Linux and 2 or 3 machines that access files shared by this server. I use Plasma on my desktop machines and I rely a lot on tags (just to clarify, Plasma uses xattrs - more specifically user.xdg.tags) to tag files. On the server I already have a couple of scripts that automatically insert some predefined tags on files.

Thing is when I try to copy and/or move files between server and desktop, depending on the protocol I used to mount the shared, I loose this information.

People suggested rsync, and it would be an excellent option if what I wanted was to keep both sides synchronized or something like that. In fact what I need is just a solution that allow me to mount a server share content and allow me to transfer files from it preserving their extended attributes, preferentially using a file manager (I use basically Dolphin or ranger).

No need to keep then synced.
