SFTPGo

[PhilipInt]

Hello !

I would like to request a new app : https://github.com/drakkan/sftpgo
It should be pretty easy to package since it already provides dockerfiles.

I don't understand how a simple sftp server app is not available on cloudron yet ? We have much more complex things or we have twisted workarounds by usings ftps setup by other apps like wordpress or lamp.

I just want a place where I can set up a ftp server, add users and permissions on folders, that's it !

Thanks !

PS: Category select is broken, I only had the choice between Comentario and AzuraCast for some reason)

Cloudron is designed for hosting web applications i.e apps that have a frontend that can be accessed using a browser. Running server programs (daemons) has not been the focus and currently out of scope.

sftpgo does seems to be more than a simple daemon, it's a web application . It fits in Cloudron.

I just want a place where I can set up a ftp server, add users and permissions on folders, that's it !

If you are not attached to the ftp server aspect, we have various apps like Nextcloud, Cubby, maybe even Surfer which does exactly this.

@PhilipInt I could give it a shot.
I already have an SFTPgo server running via. Ansible, so I know the details of hosting one and might be able to package it rather quickly.

BUT when I have the time currently projects bind me for 2-3 weeks.

Where Nextcloud is just too heavy and Cubby a tad too minimalistic SFTPGO could fill a gap (+exended other features both of the available solutions are lacking) as well as Filestash.

Started working on it.
First working state here: https://git.cloudron.io/BrutalBirdie/sftpgo-cloudron-app/-/tree/0.0.8?ref_type=tags

Definition of working:

• SFTP working - tested with FileZilla
• FTP working
• WebUI Working with features
• TODO | OIDC not configured correctly, want to help?
  https://docs.sftpgo.com/latest/oidc/?h=redirect

Quick test for "techy" users:

wget https://git.cloudron.io/BrutalBirdie/sftpgo-cloudron-app/-/raw/0.0.8/CloudronManifest.json
cloudron install --location sftpgo --image brutalbirdie/sftpgo.cloudron.app:0.0.8

[BrutalBirdie]

While on the topic.
FTP is somewhat working because it needs the passive_port_range and yes I could add the Manifest - tcpports - portCount to do this, but I dislike it.

I would be fine with SFTP only and no FTP.
But need input from the community.

[BrutalBirdie]

Update: FTP and ftpes now working.
Use Version 0.0.9

[BrutalBirdie]

WebDav also working.
Tested with curl.
e.g:

wget https://git.cloudron.io/BrutalBirdie/sftpgo-cloudron-app/-/raw/0.0.8/CloudronManifest.json
curl -T CloudronManifest.json -u REDACTED:REDACTED https://sftpgo.cloudron.dev:8888
Created

Buuuuuut this 8888 is rather ugly imho.
I would opt for an extra subdomain via. https://docs.cloudron.io/packaging/manifest/#httpports so you don't need the 8888
Will test it.

[girish]

@BrutalBirdie great progress. What's pending in the app? Do you think we should consider publishing it?

[BrutalBirdie]

OIDC stills needs work and I struggle to figure out what is wrong.
Testing all features including all the support for gcs, azure blob and S3 support for users I did not do yet.
Tests also missing for the app and needs to be done.

Imo, could be published as unstable (when OIDC is working ), so people can start testing to give feedback.

WIP - Docker Image 0.0.10

Okay so after some tinkering and reading SFTPGo Code a bit I figures out this seems the correct redirect uris for the manifest.

    "oidc": {
        "loginRedirectUri": "/web/oidc/redirect, /web/admin/oidclogin, /web/client/oidclogin",
        "logoutRedirectUri": "/",
        "tokenSignatureAlgorithm": "RS256"
    }

But now I see this:

Hmmmmmm yea.... create a user? Please? Pretty please?

Ugh.....
https://docs.sftpgo.com/2.6/dynamic-user-mod/

Did I understand this doc right? I need to write a small script which I then need to package with Cloudron?

UUUGGGGHHHHHHHHH OKKKKAAAAYYYY FINE!

[BrutalBirdie]

I've done it. . . . OIDC is now working.
Use Version 0.0.11 but now the login via FileZilla with the Cloudron password is not working
. . .

Hmmm this happend now with a FileZilla sftp:// connection:

I mean leaking the password via. maybe even an unsecured ftp connection is bad.
sftp is a secure connection so the password could be transmitted for the OIDC login? I mean the log states

Jan 26 01:51:04 {"level":"debug","time":"2025-01-26T00:56:30.132","sender":"dataprovider_postgresql","message":"user "elias.hackradt" added/updated from pre-login hook response, id: 1"}

soooo login was OK I guess but the forward back to the sftp client is somehow faulty.

What IS working, adding a ssh-pub key to my profile:

and using that key in filezilla to connect:

This could be a way to use OIDC with SFTPGo.

Scraping my head how it would be best.

[BrutalBirdie]

HAH even worse! With my current solution, you can send a random username. via. ftp and it will be created

Writing a hotfix
Fixed with 0.0.12:

• user spam via ftp clients or other clients is no longer possible.

Time for sleep

Is this ready for an "unstable" release?

[BrutalBirdie]

I'd say yes. @girish

[ctrl]

Tyvm @BrutalBirdie. Is there anything we can help to get this pushed into the official App Store? ^^

[jkammerer]

i managed to install sftpgo from the @BrutalBirdie repository. while the server kept on working the webinterface is banned - restarting doesn't resolve this.

{"level":"debug","time":"2025-02-24T12:24:20.019","sender":"dataprovider_postgresql","message":"ban time updated for ip \"172.18.0.1\", increment (minutes): 15"}

and to be honest i don't get how to update to the mentioned versions above 0.0.9 as they don't seem to be available?

[BrutalBirdie]

@jkammerer Hmmm this means the build in defender banned you for some reason.
Did you try to log in in the normal dashboard with the admin credentials or vice versa?

i don't get how to update to the mentioned versions above 0.0.9 as they don't seem to be available?

There is no other version yet. 0.0.9 is latest.
How to update? Simply get the newest CloudronManifest.json and run the update command.
Example:

cloudron update --app $LOCATION --image brutalbirdie/$IMAGENAME:$IMAGETAG
