| 7 | +# SFTP Server Access |
| 8 | + |
| 9 | +Researchers with data use agreements to access the raw data from the COVID-19 |
| 10 | +symptom survey can access the data over SFTP. (If you do not have a data use |
| 11 | +agreement, see the [main survey page](index.md) for information about getting |
| 12 | +access.) |
| 13 | + |
| 14 | +If you're not familiar with SFTP, it is a protocol for securely accessing and downloading |
| 15 | +large amounts of data from remote servers. The instructions below explain how to |
| 16 | +connect to our SFTP server on Windows or Mac. (Linux users can use the |
| 17 | +command-line `sftp` program, or most file managers can browse directly to |
| 18 | +`sftp://ftp.delphi.cmu.edu:2222` using the username and password provided to |
| 19 | +you.) |
| 20 | + |
| 21 | +## Windows |
| 22 | + |
| 23 | +[WinSCP](https://winscp.net/eng/index.php) is a free, open source SFTP client |
| 24 | +for Windows. (You can use other SFTP clients if you already have one you |
| 25 | +prefer.) |
| 26 | + |
| 27 | +1. Download and install WinSCP. |
| 28 | + |
| 29 | +2. When you open WinSCP, a login window should appear, at which point you can |
| 30 | + move to Step 3. If not, click the “New Session” button in the top left. |
| 31 | + |
| 32 | +  |
| 33 | + |
| 34 | +3. In the login window, make sure SFTP is the selected file protocol and input |
| 35 | + the credentials (server, user, password, and port) given to you in the “CMU |
| 36 | + Delphi COVID Survey Data Access” email. Click “Login” to connect. |
| 37 | + |
| 38 | +  |
| 39 | + |
| 40 | +4. You should then have access to the CSV files of individual responses from CMU |
| 41 | + Delphi COVID Survey of Facebook users. See our [response files documentation](survey-files.md) |
| 42 | + for information on how these files are formatted. |
| 43 | + |
| 44 | +## MacOS |
| 45 | + |
| 46 | +[Cyberduck](https://cyberduck.io) is a free, open source SFTP client for MacOS. |
| 47 | +(Download directly from their site for free; the App Store version costs $24.) |
| 48 | + |

| 50 | + |
| 51 | +  |
| 52 | + |
| 53 | +2. Select SFTP (SSH File Transfer Protocol) and input the credentials given to |
| 54 | + you (server, user, password, and port) in the “CMU Delphi COVID Survey Data |
| 55 | + Access” email. |
| 56 | + |
| 57 | +  |
| 58 | + |
| 59 | +3. You should then have access to the CSV files of individual responses from CMU |
| 60 | + Delphi COVID Survey of Facebook users. See our [response files documentation](survey-files.md) |
| 61 | + for information on how these files are formatted. |
