I want to copy & paste a folder and its contents in my vps. my code is below :

$conn = ftp_connect("my_ip_address");
ftp_login($conn, "username", "password"); 
$src = "/var/www/src_folder"; 
$dst = "/var/www/dst_folder"; 
ftp_exec($conn, "cp -r $src $dst"); 
if(ftp_exec($conn, "cp -r $src $dst")) echo "success copy"; 
ftp_close($conn);

but my results is ftp_exec(): Unknown SITE command.

    You cannot copy directly via FTP - there's no valid command for it. These are the available commands.

    If you must use FTP (vs. SSH for example), then I believe your best option is to download the file and then upload it to the copy destination.

    For example, if you were just dealing with a single file or empty directory, you could do something like this:

    $local_temp_file = sys_get_temp_dir() . '/tmpfile';
ftp_get($conn, $local_temp_file, $src_file);
ftp_put($conn, $dst_file, $local_temp_file);
unlink($local_temp_file);

    However, since you are dealing with a folder with all its contents, that adds additional complexity - you will need to recursively transfer all folder contents in the same manner - both when downloading and when uploading.

    You can put together a solution by referencing answers on these other posts:

    Or, you can use a library to simplify the problem a bit - for example, https://github.com/Nicolab/php-ftp-client, which has "putAll" and "getAll" methods that will help you with directories.

  • Linux on Lightsail instance is asking for a password and it's not working

    I'm trying to restart mariaDB on Ubuntu but it's not letting me.

    I enter:

    systemctl restart mariadb

    and get:

    ==== AUTHENTICATING FOR org.freedesktop.systemd1.manage-units ===

Authentication is required to restart 'mariadb.service'.

Authenticating as: Ubuntu (ubuntu)

  • How to tag and store files, by metadata, in Python?

    I want to build a manual file tagging system like this. Given that a folder contains these files:

    data/
    budget.xls
    world_building_budget.txt
a.txt
b.exe
hello_world.dat
world_builder.spec

    I want to write a tagging system where executing

    py -3 tag_tool.py -filter=world -tag="World-Building Tool"

    will output

    These files were tagged with "World-Building Tool":
    data/world_building_budget.txt
    hello_world.dat
    world_builder.spec

    Another example. If I execute:

    py -3 tag_tool.py -filter="\.txt" -add_tag="Human Readable"

    It will output

    These files were tagged with "Human Readable":
    data/world_building_budget.txt
    a.txt

    I am not asking "Do my homework for me". I want to know what approach I can take to build something this? What data structure should I use? How should I tag contents in a directory?

  • Unit testing with get request

    I am trying to create a unit test for one of my api.

    In the frontend, I send it this way...

    params = {
    participants: JSON.stringify(participants),
    section: JSON.stringify(section),
};
axios.get('/api/list', params)

    while in the controller, it receives the params this way...

    public function list(Request $request)
{
    $participants = json_decode($request->participants);
    $section = json_decode($request->section);

}

    Now, I tried making a unit test out of this. by doing...

    $params = [
    'participants' => ['id', 'name', 'rating'],
    'section' => ['id', 'code'],
];

$this->get('/api/list'.http_build_query($params))->assertStatus(200)
// $this->json('/api/list', $params)->assertStatus(200) // -> also tried this one
// $this->getJson('/api/list', $params)->assertStatus(200) // -> also tried this one
// $this->call('GET', '/api/list', $params)->assertStatus(200) // -> also tried this one

    But none of them works, it always says TypeError: json_decode(): Argument #1 ($json) must be of type string, array given.

    So, the way I built the url and the params must be all wrong,

    so my question here is that, what's the correct way of building the url so that it provides a correct url string format and the controller will json_decode the params?

  • Getting mongo authorization errors with userAdminAnyDatabase role

    I am trying to get authorization working on a mongo database on a new Ubuntu machine. I have created an admin user with the role userAdminAnyDatabase:

  • Flask redirecting leads to time-out error

    I have this simple redirect from '/' to '/home', handled by flask with

    app.py

    @app.route('/') #Redirects to home page
def redirect_home():
    return redirect("/home")

    When I use it with my browser it always leads a connection timeout error, althoug when using cURL on my vps (with -L) it does lead to the webpage correctly

        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Real-IP $remote_addr;
    }

    I used to face this issue before on my old vps and I remember fixing it by adding something to the nginx configuration but I don't remember what it was

  • Configure Gmail API on Ubuntu VPS

    How to configure Gmail API on a AWS Ubuntu VPS? I am able to make it work properly on my Linux Machine, but after I run the code on my VPS, it asks me to authenticate by visiting the URL. I copied the URL and tried authenticating myself. While authenticating myself in browser, I am redirected to localhost:<random-port>?state=... and cannot authenticate myself as it cannot connect to localhost. How can I configure this properly on my Ubuntu VPS?

    i have used the default code provided by google developers: https://developers.google.com/gmail/api/quickstart/python
