Hi,

I’m trying to configure an SSH remote storage. When I try to push my data directory I get:

```auto
$ dvc push
ERROR: unexpected error - Permission denied: Permission denied                                                                    

Having any troubles? Hit us up at https://dvc.org/support, we are always happy to help!

```

I can confirm that:

- I can connect to the server via `ssh` and `sftp`
- the URL is correct
- I have write permissions in the path (already tried by manually uploading the files via `sftp`.

I can’t really make sense of the debug message:

```auto

Hi @leandrolanzieri !

How did you set up the remote? Could you share the output of `dvc config -l --show-origin`?

Hi @daavoo,

To set up the remote I used:

```auto
dvc remote add -d archive_remote ssh://rodriguez@archive.inet.haw-hamburg.de/net/archive/rodriguez/aging_indicators_data/sram

```

The configuration looks like this:

```nohighlight
$ dvc config -l --show-origin
.dvc/config	remote.archive_remote.url=ssh://rodriguez@archive.inet.haw-hamburg.de/net/archive/rodriguez/aging_indicators_data/sram
.dvc/config	core.remote=archive_remote

```

Thanks @leandrolanzieri !

When you access the remote via `ssh`, do you provide any port/password/etc or you can access it directly with  
`ssh rodriguez@archive.inet.haw-hamburg.de/net/archive/rodriguez/aging_indicators_data/sram`  
?

p.d. Could you also try to update to the latest version `pip install --upgrade 'dvc[ssh]'`?

Yes @daavoo, I need to enter the passphrase for my RSA key to connect. Although of course I have to connect `ssh rodriguez@archive.inet.haw-hamburg.de` and then change directories. From the docs I understood that the path to the storing directory should also be part of the URL, right?

It seems I have the latest version

Got it.  
Could you try to set your passphrase in the DVC config:

```auto
dvc remote modify --local archive_remote password YOUR_ASSPHRASE

```

</div>

Thanks! That did the trick. I see that `config.local` is ignored, still a bit unsettling to have the passphrase lying around there. I would’ve expected to be prompted for it when attempting to connect. Anyways, thanks again @daavoo !

> I would’ve expected to be prompted for it when attempting to connect.

For that, you can instead set up the `ask_password` option. See all options here [remote modify](https://dvc.org/doc/command-reference/remote/modify#ssh)
