FTP-Application

A basic ftp application using python3 sockets for server and client

Simple clone the repo

$ git clone https://github.com/Sephoro/FTP-Application.git

After a succesful clone, run the command:
```
$ cd FTP-Application
```
to go into the application directory

Having gone through sections 1 and 2, on the very same command line, to start the server run the following command:
```
$ sudo python3 ftpServer.py
```
- Why sudo? Because the application uses the all important port 21, which is the official port for FTP.
- If you are using Windows on the command line just simply type the above command without sudo. For Windows run the command:
```
  python ftpServer.py
```
After running the above command you should see a similar output to the following:
- The numerals 127.0.1.1 is the server IP (Yours might be different) and the numeral 21 is the port number as previously mentioned.

Having installed PyQt5, to run the client open another command line/terminal in the same directory as the server (PS Don't stop the server!)
Execute the following command:
```
$ python3 clientGUI.py
```
- Notice that we didn't use sudo here, why? Because we are not fidling with important ports when running the client.
- Windows users, replace python3 with python.
After execution of the previous command the following screen should appear:
To contact the server
- Enter the server IP on the hostname.
- The username and passwords are stored in the users.txt file. You have two options:
  - Use the already existing usernames and passwords
  - Adding your own in the following format
    - <username> <password>
    - On terminal you can simply run the following command to add a new user:
      $ echo <username> <password> >> users.txt
- The port is 21 as previously mentioned.
- After entering the details the following should appear on the interface:
HAPPY TRANSFERRING!

The server and the client are not dependent on each other.
4.1 Client Side
If the client gives you problems mainly due to Python3 and PyQT5, you can simply run the server and hit it using other FTP Clients like FileZilla.
4.2 Server Side
The same goes for server problems, if the server gives you problems you can simply run the client on it's own and try hitting free FTP test sites such as ftp://speedtest.tele2.net :
- The hostname is : speedtest.tele2.net
- The username is : anonymous
- The password is : anonymous
- The port is 21
