# Transferring files from QEMU to your host machine ## Method 1: WebServer Serenity has a built-in web server which extends to your host machine. Open a new terminal and use the following command to start a WebServer instance for the current working directory: ```console ws . ``` Then we just open `localhost:8000` on our host machine :^) ![](WebServer_localhost.jpg) **NOTE:** Due to the fact that some browsers download unrecognized files as plain text, you may want to use something like `wget` to download the file **as is** instead. Otherwise the file may appear corrupted when the system tries to load it. ## Method 2: Mount the disk image Another way is to mount Serenity's `_disk_image` to your host machine by using the following command on *nix systems (or inside WSL): ```console cd "Build/${SERENITY_ARCH}" mkdir mnt sudo mount -t ext2 _disk_image mnt ``` ## Method 3: Archiving tool with ext2 support Some archiving tools, like [7-Zip](https://www.7-zip.org/), are capable of directly opening ext2 images like Serenity's `_disk_image`. With these, you can open the disk image like any other archive and extract the files you need. For WSL users: If you have the image on your native WSL drive (recommended), this drive can be opened in Explorer by manually opening `\\wsl$` (not visible in the Network tab!) and then the "network share" corresponding to your distro. ## Method 4: Enable OpenSSH on host and use sftp client on SerenityOS - Setup OpenSSH server on your host. For windows: Google is your friend (https://docs.microsoft.com/en-us/windows-server/administration/openssh/openssh_install_firstuse) For linux: Google is your friend. - Ensure that you already have a working SerenityOS working build. ```console $ Meta/serenity.sh rebuild-world ``` - To enable OpenSSH package from SerenityOS: (initial directory is SerenityOS ROOT_DIR) ```console cd Ports cd openssh ./package.sh cd ../.. Meta/serenity.sh run ``` - From within SerenityOS, check that you have a working sftp app: ```console courage:~ $ sftp ``` The expected response will be: ```console courage:~ $ sftp usage: sftp [-46aCfNpqrv] [-B buffer_size] [-b batchfile] [-c cipher] [-D sftp_server_path] [-F ssh_config] [-i identity_file] [-J destination] [-l limit] [-o ssh_option] [-P port] [-R num_requests] [-S program] [-s subsystem | sftp_server] destination ``` - Assume that you have a working OpenSSH server as mentioned earlier, with an IP address of 192.168.0.11. - Assume that you have a valid user on that host with account name user1. - Assume that you are currently inside the folder from which you want to transfer the file(s) from. - Local User: anon - Remote User: user1 IP Address: 192.168.0.11 - Connect to remote server via sftp ```console courage:~ $ sftp user1@192.168.0.11 The authenticity of host '(192.168.0.11)' can't be established. ECDSA key finger print is SHA256:Iav!m/E0cHJBnzSk0hJEZnBZ2F3LBL4wxhyv4nrfPtU. Are you sure you want to continue connecting (yes/no/[fingerprint])? yes user1@'s password: Connected to 192.168.0.11 ``` - By this time, you have successfully connected and logged on to the remote host. - You can get more information by typing ` help `. - The most often used (simplified) sftp commands are ` ls `, ` cd `, ` put [filename] `, ` get [filename] `, and ` quit `. I said simplified since the actual commands have many more options. - Be aware that there will be a time you would think that nothing is happening since the cursor just stares back at you. It is always waiting for your next instruction. Typing ` quit ` or ` bye ` will close the program. - Congratulations. Pat yourself at the back.
