Termux: Enable Wake-Lock

Smartphone Configuration

The Android 11 smartphone is not rooted and it has never been rooted

Three gigabytes of RAM

Four cores/CPUs, "MT6761V/WAB" according to "neofetch" in Termux

Create Termux Sessions: termux (Session 1), usbredirect (Session 2), qemu (Session 3)

From The termux Session: Create a disk, a file named vmtest, for the virtual machine (VM), the QEMU Linux Server will be installed on vmtest

~ $ mkdir $HOME/termux-qemu-usb ~ $ cd $HOME/termux-qemu-usb ~/termux-qemu-usb $ qemu-img create -f raw -o preallocation=full vmtest 3G Formatting 'vmtest', fmt=raw size=3221225472 preallocation=full ~/termux-qemu-usb $

On the QEMU Linux Server enable passive mode and anonymous mode for vsftpd by adding the following directives to the default server configuration file at "/etc/vsftpd/vsftpd.conf"; the configuration works for "lftp" and "mc" ("FTP Link" in the Midnight Commander file manager) and the FTP clients must use the passive mode and port 50021; anonymous is the username and no password is required:
