If you want to prevent other people from logging into your computer, you can add passwords to Tinycore.
If you are using the Extlinux bootloader, another option is to add passwords to Extlinux. For more information, see Extlinux Passwords.
To add a password for user tc, open the terminal and type
To add a password for root, type
The procedure described above stores the password using 8-byte parity, so the password will be 8 characters long, i.e. “passwd 123456789” will allow to login using “12345678” or “12345678blahblah” as password. This occurs on 4.1 and 4.2. Use “passwd -a md5” instead. (see http://forum.tinycorelinux.net/index.php?topic=9215.0)
If you use Backup, to save passwords, add
Backup when shutting down the computer.
If you use persistent opt, open the terminal and type
sudo cp /etc/shadow /opt/shadow
Add the following to /opt/bootsync.sh
sudo mv /etc/shadow /etc/shadow_old sudo cp /opt/shadow /etc/shadow
Note that this will apply group staff and mode g+w to /opt/shadow on each boot, as it's the case with every file in /opt.
To be prompted for Username and Password when logging in, add the bootcode
to the bootloader.
Log in as tc, not as root.
If you want to perform root tasks, use sudo before commands.
If you want commands executed every time you start the computer, add them to /opt/bootsync.sh or /opt/bootlocal.sh.
/opt/bootsync.sh is run early in the boot process.
/opt/bootlocal.sh is run later in the boot process.
Most commands should go in /opt/bootlocal.sh, except commands you want executed early in the boot process.
