- Test IPs that your system has recently contacted to see if they are still reachable. # Loop over the output of ip n # Use $(echo | cut) to parse just the IP address # Ping the IP once to see if it is alive # Test the exit code and report that the IP is "UP" or "DOWN" 3. Optionally, clean up the output # Using /dev/null, hide the output of ping so that only your IP UP/DOWN is displayedarrow_forwardI made a TCP server using socket python,basically my server can: - Upload (“put”) request: The client should, at the very least, open (in binary mode) the local file defined on the command line, read its data, send it to the server through the socket, and finally close the connection. - Download (“get”) request: The client should, at the very least, create the local file defined on the command line (in exclusive binary mode), read the data sent by the server, store it in the file, and finally close the connection. To avoid accidents, the client should deny overwriting existing files. - Listing (“list”) request: the client should, at the very least, send an appropriate request message, receive the listing from the server, print it on the screen one file per line, and finally close the connection. I want you to draw an ER diagram that can show the process above please.arrow_forwardcd /bin/user/directory/abc is an example of relative pathname. True or false.arrow_forward
- Create two separate Python scripts. The Client programme sends the Server programme an arbitrary string across the network. After parsing the Client String, the Server application will append the "Back to You" string to it before sending the whole thing back to the Client.arrow_forwardimport socket def authenticate_user(tcp_socket): while True: response = tcp_socket.recv(1024).decode() print(response) username = input() tcp_socket.sendall(username.encode()) response = tcp_socket.recv(1024).decode() print(response) password = input() tcp_socket.sendall(password.encode()) auth_response = tcp_socket.recv(1024).decode() if "successful" in auth_response: print(auth_response) return True else: print(auth_response) def receive_items(tcp_socket): while True: response = tcp_socket.recv(1024).decode() if "Item List:" in response: print(response) while True: item = tcp_socket.recv(1024).decode() if not item.strip(): break print(item) break def select_items(tcp_socket): selected_items = [] while True: item_id = input("Select item by entering…arrow_forwardPlease do not use a python code already on the internet. The following code must be written in python for this HW assignment. I will provide a skeleten for the code and you must write some lines of code to satisfy the objective of the prorgram. you need to develop a web server that handles one HTTP request on at a time. the web server should acceptand parse the HTTP request, get the requested file from the server’s file system, and create an HTTP responsemessage consisting of the requested file preceded by header lines, and then send the response directly tothe client. If the requested file is not present in the server, the server should send an HTTP “404 NotFound” message back to the client. Dont need the hole code just right the information and code it to the skeleten pictures below.arrow_forward
