shfs - easy mounting filesystems through ssh

lanrat · 2004-12-18 03:06:55

This is a small and easy to use kernel module and tools for mounting remote filesystems through ssh connection.
Latest patches are already included.

Hey, this is nice. Finally I might be able to use something other than NFS(It always takes ages to start it up).

Thanks for the link

make sure you have portmap running when you use NFS!

also make sure network is up and running before starting nfsd, otherwise it takes about five minutes.

Hmm..
Are there any comparisons with nfs for speed/reliability?
I can imagine compression might help for poor connections, but ssh has it's own overhead too. It might just be better to tunnel nfs..

Has anyone tried this yet? Care to share your experience? How do you like it?
I am always intruiged by different ways to secure things...especially considering I have been pondering securing ltsp stuff lately.

I'm just guessing, but I think this shfs might prove a bit slower than NFS with old endpoints (like in my case), due to encryption and so forth...
On the other hand, it's probably a lot more easy to use than a encrypted nfs tunnel (with openvpn or similar)

AFAIK shfs is indeed quite slow when transferring large files (people report about 2MB/s). But it's one of the easiest to setup so it's just your choice (right tool for the right job).

If you only want to copy some files then scp is the best tool IMO. It's also reported to be the fastest (BTW it can eat all CPU too :-)).

IMO shfs is something between scp and encrypted nfs/samba/... It's a good tool for quick mounting of remote directories if the coping speed is not the most important thing for you (network admins should like it - easy and secure configs editing, mounting remote abs directory trees, etc. etc.).

Gentoo forums have plenty of threads about shfs (opinions, comparisions, examples of fstab, etc.) - just search for shfs...

EDIT: this is a good place to start reading about different filesystems including encrypted fs:

(steganographic fs? :-))

Yes, I do have portmap running, since if it isn't running an error is returned. also, the network is on. What I have been doing lately is using sftp, since it keeps things simple for me. I don't like scp(I have to know the exact path to use it, and to do that I open another VC on ssh :oops: )
I think I'll try shfs, and since I was trying to figure out how to use the kernel-mode nfs in any case, I might as well use this .

alexmat · 2005-03-06 01:27:31

you should add

depmod -a

to the pkgbuild... everytime I reinstall for a new kernel I forget and end up trying to figure out why stuff won't mount and I can't modprobe shfs. lol, yes I'm that retarded

lanrat · 2005-03-06 01:58:41

Done :-)

alexmat · 2005-03-06 20:15:57

Works great

Thanks a bunch.
