Cannot mount Hetzner storage box for backups using SSHFS
-
I made a clean installation of cloudron on a ubuntu hetzner server.
After that I could mount the storage box with the procedure I tried before without problems.So I dont know what was wrong. But now everything working fine.
Thanks -
@girish
I tried this exact same setup. I was able to connect to the storage via SFTP and my SSH key and I copied my private SSH key as instructed to Cloudron.When I now try to save the backup settings using SSHFS it keeps working and never finishes. The log says
Jan 14 11:40:33 box:shell addMount spawn: /usr/bin/sudo -S /home/yellowtent/box/src/scripts/addmount.sh [Unit]\nDescription=backup\n\nRequires=unbound.service\nAfter=unbound.service\nBefore=docker.service\n\n\n[Mount]\nWhat=uxxxxx@uxxxxx.your-storagebox.de:/\nWhere=/mnt/cloudronbackup\nOptions=allow_other,port=23,IdentityFile=/home/yellowtent/platformdata/sshfs/id_rsa_uxxxxx.your-storagebox.de,StrictHostKeyChecking=no,reconnect\nType=fuse.sshfs\n\n[Install]\nWantedBy=multi-user.target\n\n 10 Jan 14 11:40:44 box:shell addMount (stdout): Failed to mount Jan 14 11:40:44 box:shell addMount code: 3, signal: null Jan 14 11:42:04 box:shell removeMount spawn: /usr/bin/sudo -S /home/yellowtent/box/src/scripts/rmmount.sh /mnt/cloudronbackupNot sure what else I can try.
Edit: magically and waiting one night it works now.

I'm sorry to reopen this, but I've been trying to connect Hetzner volumes and I'm stuck with the key-gen command at the server. I'm pretty sure there's something I'm understanding poorly, but I would like to connect the Volumes with my Cloudron instance, but there's no way I can run key-gen on the Volumes via SSH to get them connected.

Hetzner Volumes
Hetzner Cloud Volumes are a very different product to their Storage Boxes.
I don't think you can access them in the same way.
You can definitely use them as a Cloudron Volume though. I think you just have to mount them on your VPS server using fstab first.

Oh I'm sorry, just to clarify, I'm trying to use Storage Boxes as Cloudron Volume.

Ah, OK. I've got that set-up but I've only ever used CIFS and not SSHFS so not sure what you have to do myself sorry.

It says as much that it is a restricted shell. Not sure how to generate keys though, maybe a question for hetzner support.

Ah, but Girish gave instructions above in this very thread!
As @robi said if you don't have ssh-keygen installed, install it.

For me. It's silly. All the guide is out of date. With new created storage box, there isn't sub dir and ssh pub key is not yet allowed in storage box and storage box's pub isn't in my pc known_hosts, I have to add my pub key to storage and run sshfs command once time to get pub key of storage box. So because of new user without subdirectory, the "remote dir path" after colon should be RELATIVE path or empty "" in this case not "/". uxxxxxx@uxxxxxx.your-storagebox.de: /mnt/local/mount/path -o port=23,IdentifyFile=/home/username/.ssh/id_rsa ....

Hey folks
I recently struggled a bit with those steps as well, but it was because I had set a passphrase for my SSH keys at creation time and Cloudron does not prompt for that anywhere.
Is that in the plans for the future @girish ?Thanks !
-
@SansGuidon how would automatic mounting on boot work if the ssh key had a passphrase? If you put the password in clear text in a config file, it's probably more insecure than having no password at all (especially if you reuse passwords or a part of it...).
-
@girish it could be an option to do it manually the first time for security reasons, with login keyring asked once.
I mean I'd like that the option is at least given
, and of course not hardcoding the passphrase in the form. -
@SansGuidon yeah, maybe. Have to investigate
Feel free to open a thread in https://forum.cloudron.io/category/97/feature-requests and we can see how much interest is there. -

It wouldn't. But I've got the same problem.
I've already got a pair of SSH keys (with a passphrase) that I can successfully use to login to both my Storage Box and my VPS.
But of course this doesn't work for the Backup set-up because it requires a passphrase.
So, how can I create an additional set of non-passphrase keys just for use with the Storage Box?
Thanks!

You should be able to follow the docs at https://docs.hetzner.com/storage/storage-box/backup-space-ssh-keys for generating and using new keys.

@nebulon thanks but those Hetzner docs just aren't clear nor detailed enough and having read them lots of times I'm still none the wiser.
It says:
Warning: With the default settings, using ssh-keygen will overwrite an existing SSH key! As an alternative, with the parameter -f, you can specify a different file path.
But that just isn't enough detail for me.
It isn't at all clear about how to create/ add an additional pair of ssh-keys whilst keeping the existing ones intact.
-
So you would create a new key pair with
ssh-keygen -f ./newkeyat least on linux. When prompted for a password, just press enter. Then you have the keypair in the current working directory where you ran that command.From there you can upload the public portion of the key as mentioned in the hetzner docs and use the private key for your Cloudron configs.
