>From what I understand, fuse is the lower layer of filesystems such as captive ntfs and shfs. Captive ntfs uses the win32 drivers for ntfs via user space to allow you to write to an ntfs partition.

Help! And there's the rub with FUSE. You need a setuid-root helper to perform the actual mount. Check the permissions on /usr/bin/fusermount. On my system, they've set it up for setuid-root but Fedora has deemed this to be enough of a security risk that you have to be in the fuse group to run it: -rwsr-xr-- 1 root fuse 22512 May 3 09:49 /usr/bin/fusermount

Why is this good? Because *anything* you can think of that you'd like to access as a filesystem, you can, without writing a kernel driver. http://fuse.sourceforge.net/wiki/index.php/FileSystems It works via the fuse module, /dev/fuse, and some (transparent) helper programs. > What good is FUSE to me? I've Googled till the cows come home, but I do > not understand the responses. I've been using the "sshfs" fuse module, and its one of the greatest things I've experienced in Linux in recent years. Lets say you have ssh access to another machine, you need to have FUSE support on your local kernel, then its just a matter of, mkdir ~/ssh/otherhost sshfs -o idmap=user me@otherhost:/ ~/ssh/otherhost ls ~/ssh/otherhost It sets up an sftp (ssh ftp protocol) session in the background, and I can now access whatever files I would have access to via ssh/sftp, right on my local system. Basically, it reduces, ssh otherhost cd somedir/ $EDITOR foo.txt exit to, cd ssh/otherhost/somedir/ $EDITOR foo.txt Working with files reduces to "mv", "cp", etc. No need for kioslaves, gnome-vfs, or other such madness. When I'm done, fusermount -u ~/ssh/otherhost At least on the small scale, which is all I really care about, it is SO much easier than setting up NFS, I don't even build NFS support into my kernels anymore. *No* setup is required on the other side (other than running sshd), no root access required on local side. I wouldn't be surprised if Plan9 and other OSs have had similar capabilities, but I haven't spent enough time with them, maybe someone else can comment. In any case, it works on Linux, and I'm happy. -Jamie

well, my first responce was that it was an encryption system for disks, but then found http://www.ricardis.tudelft.nl/~vincent/fusesmb/ saying it is a network browsing system. then also found: http://rescuecd.pld-linux.org/download/2006-06-18/RPMS which lists fuse as the following: ntfsprogs-fuse 1.13.0-3 NTFS FUSE module (ntfsmount) and libfuse 2.5.3-3 Filesystem in Userspace so, i guess my answer is i have no idea --- ken jones <kjones(a)ziplink.net> wrote: > Would somebody please explain to me what exactly FUSE does? > > I succeeded in using fusexmp to mount my root directory into > /tmp/fuse2.5.3/example.

FUSE = FileSystems in user space (you knew that....) An example: I use sshfs (http://fuse.sourceforge.net/sshfs.html) to mount a file system which I can access via ssh but cannot mount it via NFS (because the file system is behind a firewall). I can mount it as a mere user (not root). Traditionally, all file system mounts had to be done as root (relaxed later for removeable media such as floppies, CD/DVD, USB memory, etc). In the case of NTFS, I'm not sure I see an advantage either way. Perhaps FUSE is just another way to access data stored on an NTFS partition. I'm not certain, but I think the "big deal" about FUSE is that the user can do it without requiring root.
