So I am working on a homework project for my network architure class were I have to devlop an FTP program using UDP (not TCP). I was able to get my GET and PUT functions to send a 21byte test file and it worked. However when I tried to do a 1MB file the program hanged and did not send all of the data. I need to be able to send files of 1MB, 25MB, 50MB, and 100MB. Here is my code.

GET (Client Side)

``` private static void getFile(String serverFilePath, String clientFilePath) throws IOException { clientFilePath = clientFilePath.replaceAll("^\"|\"$", ""); //Strip quotes if any. if(!clientFilePath.startsWith("/")) clientFilePath = currentDir + "/" + clientFilePath;

sendMessage("GET " + serverFilePath);

//Write file to client try (FileOutputStream fos = new FileOutputStream(clientFilePath)) { while (true) { byte[] buffer = new byte[BUFFER_SIZE]; DatagramPacket packet = new DatagramPacket(buffer, buffer.length); socket.receive(packet);

String data = new String(packet.getData(), 0, packet.getLength()); if (data.equals("DONE")) break;

fos.write(packet.getData(), 0, packet.getLength()); } } System.out.println("[Client] File downloaded successfully."); } PUT (Client Side) private static void putFile(String clientFilePath, String serverFilePath) throws IOException { clientFilePath = clientFilePath.replaceAll("^\"|\"$", ""); //Strip quotes if any. if(!clientFilePath.startsWith("/")) clientFilePath = currentDir + "/" + clientFilePath;

sendMessage("PUT " + serverFilePath);

//Upload file to server try (FileInputStream fis = new FileInputStream(clientFilePath)) { byte[] buffer = new byte[BUFFER_SIZE]; int bytesRead; while ((bytesRead = fis.read(buffer)) != -1) { DatagramPacket packet = new DatagramPacket(buffer, bytesRead, serverAddress, SERVER_PORT); socket.send(packet); } sendMessage("DONE"); } System.out.println("[Client] File uploaded successfully."); } ```

GET (Server Side) ``` private static void handleGet(String filePath, InetAddress clientAddress, int clientPort) throws IOException { filePath = filePath.replaceAll("^\"|\"$", ""); //Strip quotes if any. if(!filePath.startsWith("/")) filePath = currentDir + "/" + filePath;

//Check is file exists File file = new File(filePath); if (!file.exists()) { sendMessage("[Server] Error File not found", clientAddress, clientPort); return; }

//Write file to server try (FileInputStream fis = new FileInputStream(file)) { byte[] buffer = new byte[BUFFER_SIZE]; int bytesRead; while ((bytesRead = fis.read(buffer)) != -1) { DatagramPacket packet = new DatagramPacket(buffer, bytesRead, clientAddress, clientPort); socket.send(packet); } sendMessage("DONE", clientAddress, clientPort); } } ```

PUT (Server Side) ``` private static void handlePut(String filePath, InetAddress clientAddress, int clientPort) throws IOException { filePath = filePath.replaceAll("^\"|\"$", ""); //Strip quotes if any. if(!filePath.startsWith("/")) filePath = currentDir + "/" + filePath;

File file = new File(filePath); try (FileOutputStream fos = new FileOutputStream(file)) { while (true) { byte[] buffer = new byte[BUFFER_SIZE]; DatagramPacket packet = new DatagramPacket(buffer, buffer.length); socket.receive(packet);

String data = new String(packet.getData(), 0, packet.getLength()); if (data.equals("DONE")) break;

fos.write(packet.getData(), 0, packet.getLength()); } } sendMessage("DONE", clientAddress, clientPort); } ```

Ok I was copying a bunch of games from one of my Windows drives over to my phone while booted into Linux. And I got this error that says "libmtp error: Could not open source file". Thankfully I was able to copy the files when I was booted into Windows but it would be nice if I could Transfer files from my Windows drives without having to reboot into Windows. Is there a way I can fix this problem.

I think it might have to do with the ntfs file system because I copied one of the files from the phone back to my Desktop which is ext4 and then back to the phone without any issues. I already tried installing ntfs-3g which was already installed on my distro.

Long story short I was messing around in the terminal and messed up my Linux Mint Installation and now when I boot into Linux I only get a CLI and don't even see the Linux mint logo. I tried to restore to a previous state using Timeshift but it did not work so I ended up taking a live usb and backing up all my important documents to an external drive. I want to just do a fresh installation but unfortunally for me the boot drive is also the same drive I use to boot into Windows (which I am still able to boot into from GRUB). Is there a way I can reinstall the OS without affecting my ability to boot into Windows?

Ok so I was trying to clone 512gb nvme ssd to my new 2tb drive with clonezilla and it keeps taking me to automatic repair. I unplugged the original drive and replaced it with the new one before booting. I ran a chkdsk both times before cloning.

The first time I cloned the drive i used these settings:

device to device beginer disk to local disk Chose my source and target Skip disk checking -k0 use source partition table

Then I tried these settings:

device to device expert disk to local disk Chose my source and target Left everything as default -k1 Create partition table proportionally

I also plan on partitioning half of the drive so that I can dual boot linux as Window 10 is reaching eol and I don't want anything to do with Windows 11 and I still need Windows for gaming.
