# Descripción general de la transferencia de archivos

A file transfer service is offered to customers to share files with Thales backend applications.

Only SFTP protocol (with username/password) is offered as of today.

### User Management

Users willing to access to FTP service shall be enrolled through Thales Onboarding Portal (TOP) and granted with FTP access role.

To do so, customer shall send a request to [bp.allynissupport@thalesgroup.com](https://thales-dis-dbp.stoplight.io/docs/tsh-infra/bp.allynissupport@thalesgroup.com).

The first time a "ftp application" role is assigned to a user, this user will receive an email with temporary username/password only valid for 24h.

User must then set his password using following link: <https://portal.dbp.thalescloud.io/auth/index.html?idp=mfaLess&kc=false#/signin>

Password minimal length is 48 characters and it must includes uppercase, lowercase letters, special characters and numbers.

### FTP Folder layout <a href="#ftp-folder-layout" id="ftp-folder-layout"></a>

Two folders will be available for user's organization.

* **\<customer\_id>/in**: used by customer for sharing the input files
* **\<customer\_id>/out**: used by Thales solutions for sharing the output files/reports

E-Mail templates shall be stored in the following directory:

* **\<customer\_id>/in/configuration/emailTemplates**

The \<customer\_id> is replaced by the customer's organization id for the user.

Note that the ftp user's home directory is \<customer\_id>.

Users are not allowed to access parent directory.

### File Format <a href="#file-format" id="file-format"></a>

Two different file types shall be exchanged through FTP service:

* **Batch Processing Files**
* **E-Mail Templates**

The format of the Batch processing files are defined in the relevant solution specifications (e.g. Apple Pay).

Please contact the integrator/project manager assigned to your project in case you don't have these specifications.

E-Mail templates are in **HTML** format and shall be **UTF-8** encoded.

### FTP Endpoint

| Environment | Hostname                   | IPs                                                    |
| ----------- | -------------------------- | ------------------------------------------------------ |
| Staging     | ftp.dbp-stg.thalescloud.io | <p>52.44.66.156<br>44.199.38.220<br>44.198.35.31</p>   |
| Production  | ftp.dbp.thalescloud.io     | <p>54.159.252.131<br>54.225.221.171<br>3.81.155.41</p> |

### Connectivity testing

You can test the connectivity with lftp.

Hereafter is a test a file upload with sftp command on Linux through a proxy server, here uploading a file name /tmp/dummy and deleting it afterwards:

```vim
echo "hello world">/tmp/dummy && lftp -d sftp://ftp.dbp-stg.thalescloud.io -u '<ftp_user>,<ftp_password>' -e "set sftp:connect-program 'ssh -ax -o ProxyCommand=\"/usr/bin/nc -X connect -x <proxy_name>:<proxy_port> %h %p\"'; cd in; put /tmp/dummy; rm dummy; bye"
```
