remoteshare Plugin and sshfs

1st Official Post

    Hi,


    I am using OMV since quite some time but I am new in this forum, so first of all: Hello to everybody and thanks for this nice peace of software!

    On my OMV Server i have the remoteshare plugin installed and some old forum posts indicate that sshfs would be supported.
    I can not find a section in the Web-GUI to configure a sshfs share. Looking into the source code on github
    shows something strange to me. A share type sshshare seems to be supported, but the JavaScript Sshfs.js is not included in the right place.


    My question is: What needs to be done to enable sshfs / sshshare in the Web-Gui or are there any good reasons not to use it with OMV?


    Thanks in advance

    Did not help:



    Before uninstall:

    Code
    root@omv:~# apt-cache policy openmediavault-remoteshare
openmediavault-remoteshare:
  Installiert:           1.1
  Installationskandidat: 1.1
  Versionstabelle:
 *** 1.1 0
        995 http://packages.omv-extras.org/debian/ stoneburner/main amd64 Packages
        100 /var/lib/dpkg/status


    After re-install:


    Code
    root@omv:~# apt-cache policy openmediavault-remoteshare
openmediavault-remoteshare:
  Installiert:           1.1
  Installationskandidat: 1.1

 *** 1.1 0
        995 http://packages.omv-extras.org/debian/ stoneburner/main amd64 Packages
        100 /var/lib/dpkg/status


    It is not picking up a release of the remoteshare plugin in omv-extras.org-stoneburner-testing but is still using -stable


    This is a production system, so I hesitate to forcefully install from command line via


    Code
    apt-get -t  stoneburner-testing install remoteshare

    Edited once, last by Zoki ().

    Never mind.


    I wonder what the issue is:

    • From the comments it looks like it had been implemented in 2014
    • In the repository there is a file Sshfs.js
    • sshsahre seems is handled by the back-end

    Who is maintaining this plugin?

    I started work on it and removed it because it had too many issues. The plugin needs to be re-written. I have some ideas for it but it will be for OMV 3.x.

    omv 7.4.7-1 sandworm | 64 bit | 6.8 proxmox kernel

    plugins :: omvextrasorg 7.0 | kvm 7.0.14 | compose 7.2.3 | k8s 7.2.0-1 | cputemp 7.0.2 | mergerfs 7.0.5 | scripts 7.0.8

    Please try ctrl-shift-R and read this before posting a question.

    Please put your OMV system details in your signature.
    Please don't PM for support... Too many PMs!

    Here's a way to do it.


    1. OMV side
    - check the ssh service via the Web UI: Services » SSH: Enable
    - check/create the dir you want to be mounted remotely via ssh, with the wanted ACL (eg read/write/execute)
    - you need to add a bash login instead of pure shell or dash. Otherwise things like autocomplete or ctrl+r don't work. You can do that from the users management
    - add the user to sudo group or switch to root using su.
    - create a folder that you want for home and place the path in /etc/passwd in the the fifth field. Don't forget to chown the folder to the owner.
    - know the user ID (eg with `grep USER /etc/passwd` or `cd && ls -lan .` check the third column)


    2. Client side
    - check you have access to your OMV via ssh
    - optionally set up ssh key authentication (avoid the hassle to enter the password upon each ssh/fs access and mounting)
    - install sshfs
    - create the dir where you wanna mount the remote dir locally `mkdir /path/to/sshfs/server/dir`
    - mount it with `sshfs -o idmap=user,allow_other,uid=YOUR_UID,gid=YOUR_GID user@omv:/media/UUID/DIR /path/to/sshfs/server/dir -C` (tip: make an alias to mount it with eg `sshfs_omv`)


    The 'uid=,gid=' allows for rw access even if the user on the client has different uid and gid than on the OMV server
    Check it works (eg `ls /path/to/sshfs/server/dir/`)
    Unmount it : `fusermount -u /path/to/sshfs/server/dir`


    There might be other ways but that one just works.
    Edit: added the user $HOME steps to mount via ssh as a user (vs root).

    @datruche Thank you for this little write up, but I needed it a bit different.


    May this be helpfull for others:


    My intention is to mount the file system of a remote server 'REMOTE-SERVER' into my local omv 'OMV' using the web gui and use it as if it was a omv share.


    It is not possible using the web gui so what I did instead is:

    • Create a new ssh key using the web gui
    • Add the public key to ~/.ssh/authorized_keys file on the remote server
    • Create a shared folder 'SSHFS' using the web gui
    • Log into OMV via command line
    • find the new ssh key in /var/lib/openmediavault/ssh/keys/openmediavault-1c69f786-25aa-4941-b5b6-4ef49514ec26
      (Finding the correct key can be a bit tricky, as the uuid will be different for every key, hint: check the comment)
    • Mount the remote server via sshfs -o idmap=user -o allow_other -o uid=YOUR_UID -o gid=YOUR_GID -o IdentityFile=PATH_TO_PRIVATE_KEY_FILE -o ServerAliveInterval=15 USER@REMOTE-SERVER:/PATH /media/UUID/SSHFS -C


    Advanced:

    • To have correct uid / gid in the file system, set up a user-id mapping file USER_MAPPING and group-id mapping file GROUP_MAPPING and use -o uidfile=USER_MAPPING and -g GROUP_MAPPING instead of -o uid=... and -g gid=...
    • To mount the remote file system on startup edit (as root) /etc/fstad and add a line
      sshfs#USER@REMOTE/SERVER:/PATH /media/UUID/sshfs fuse uid=YOUR_UID,gid=YOUR_GID,<other_options>,umask=0,allow_other,_netdev 0 0

    No you can use the remote servers file system like any shared folder
