drakplayground: Transfer files from guest os to host.

[tfrist]

Hi,

I know there is a way to copy file from the host onto the guest, using drakplayground 0 and then executing copy(host_file_path) method.
Is it possible to go the reverse direction? copy files from the guest to the host.
Thanks.

It is not offered by current version of drakplayground, but you can hack current methods to get the injector instance and call read_file:

*** Welcome to drakrun playground ***
Your VM is now ready and running with internet connection.
You can connect to it using VNC (password can be found in /etc/drakrun/scripts/cfg.template)
Run help() to list available commands.

I will leave the issue open as it is good feature request, I'm also missing that option.

Great idea.
I wrote a method in playground.py as below:

def copy1(self, remote, local): ####################################################
    remote = Path(remote)       
    self.injector.read_file(self.desktop / remote.name, local)

and added it in main() as:

with DrakmonShell(args.vm_id, args.dns) as shell, graceful_exit(
    start_dnsmasq(args.vm_id, args.dns)
):
    helpers = {
        "help": shell.help,
        "copy": shell.copy,
        "copy1":shell.copy1, #################################
        "mount": shell.mount,
        "drakvuf": shell.drakvuf,
        "vm": shell.vm,
        "run": shell.run,
    }

Finally, I can copy file from guest using copy1(), like copy1("log.txt", "/home/log.txt"). and it worked as expected!
Thanks.
