I have a domain hoster that provides access via SSH.

My platforms are:

  • Gentoo 2.6.36-r5
  • Windows (XP/Vista/7)

I work on my Windows, I use Gentoo to do all the magic Windows can't do.

Therefore I use sshfs to mount the remote public directory for my domain to /mnt/mydomain.com. Authentication is done via keys, so lazy me don't have to type in my password every now and then.

Since I do my coding on Windows, and I don't want to upload/download the changed files all the time, I want to access this /mnt/mydomain.com via a samba share.

So I shared /mnt in samba, all mounts except mydomain.com is listed on my Windows Explorer.

My theories are:

  1. sshfs does not set the mountpoint uid/gid to something that samba expects
  2. samba does not know that it has to include the uid/gid that /mnt/mydomain.com has been set.
  3. All above is wrong, and I don't know.

Here are configs and output from console, need anything else just let me know. Also no errors or warnings that I take notice of being relevant to this issue, but I might be wrong.

For an easier read:

  • myusername@mywebhotel.com
  • /home/to/pub/dir/
  • /mnt/mydomain.com/

options:

  • comment=sshfs
  • noauto
  • users
  • exec
  • uid=0
  • gid=0
  • allow_other
  • reconnect
  • follow_symlinks
  • transform_symlinks
  • idmap=none
  • SSHOPT=HostBasedAuthentication

Help!

IIRC, HostbasedAuthentication is not recommended to use (the user-based PubkeyAuthentication is preferred) –  grawity Mar 26 '11 at 17:24

sshfs is a FUSE-based filesystem, and the FUSE layer does not allow other users to access its mounts by default, for security purposes. You have allow_other in options, but it will be ignored until you also edit /etc/fuse.conf to include user_allow_other.

When exec'ing "ps aux", left column states root for both sshfs and smbd processes. I "parse" this as both runs with the same privileges. From the ls -lah output, you see the uid is not root, this uid is set by sshfs, but I can't set it, atleast not with changing uid/gid in options. I believe samba somehow think it has to exclude that specific directory with uid/gid 68591. (Trying to clear some confusion on my part.) –  CS01 Mar 28 '11 at 8:08
    
@CS01: The "master" smbd runs as root, but that is not true for connection handlers – if you log in over SMB as "jim", your smbd process also switches to the UID of "jim". –  grawity Jan 11 at 18:21

Why don't you mount sshfs directly from Windows?
There are couple of free solution for that (see here and here for more info).
