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?

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.

FUSE??

by ken jones

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. I also succeeded in unmounting with fusermount -u. I do not understand why I should want to. This all started when I upgraded the kernel and the type ntfs file system on the other half of my dual mounted system refused to "mount". I got distracted into FUSE then remembered to install the matching kernel-module-ntfs below. Now I am again successfully using 'smbmount' to mount ntfs file types. I am running Fedora 2.6.17-1.2142_FC4 with kernel-module-ntfs-2.6.17-1.2142_FC4-2.1.27-0.rr.10.4.i686.rpm What good is FUSE to me?

I would pick the models with the built-in Intel Accel 950 chip or equivalent. There are open source 3D video accelerated drivers for those. You might need a little open source utility to set the VESA BIOS video resolution table for WXGA, though. I recently worked on one and had to get a program called "855resolution" or "915resolution", which runs at bootup. Xorg worked fine at 1400x1050 after that. http://www.geocities.com/stomljen/
