    Thumbs up Auto-downloading when Ubuntu automatically is turned on at night?!

    The service pack that I use offers gratis download at night (1AM to 6AM). I usually sleep at 22:30 to wake up soon!
    I need to turns the ubuntu at 00:50 AM for downloading; here is my method. please read it and modify/promote it for a better scheduler task!

    0. (every week, each day) I've set the bios to turns on the computer at 00:50

    1. At 22:10 O'clock => I gather all my straight downlkoad links in a file called "dl.txt"

    2. At 22:20 O'clock => I change my user (which is administrator) config from "asking password" to "auto login". this is need to login to ubuntu directly.

    3. I've added a simple command to "crontab -e":
    Code:
    00 01 * * * aria2c -c -x16 -s16 -k 1M -m10 --retry-wait=30 -i "/PATH/TO/dl.txt" -d "/PATH/TO/DOWNLOAD_DIRECTORY/" -l dllog --log-level=notice
    aria2c --on-download-complete echo "PASSWORD"|sudo -S shutdown -h now
    59 05 * * * echo "PASSWORD"|sudo -S shutdown -h now
    4. In the morninig, I re-cofnfig my user to off auto-login (this is my everyday task )

    If you have any idea about improving this instuction, please me to know

    does your "silence" means that my solution is the best way?

    Hi, I dont think the silence means anything, It looks
    like you are using the tools available to you to get your
    desired results. There are many different ways to accomplish
    a task using linux. No doubt some super coder would write a
    program in some obscure language and the code would be
    unreadable to the average user. I'm sure as time goes on you
    will add tweaks and changes,bells and whistles. For now, if
    it's not broke, why fix it?

    Hi, I tested this, the command anyway and it seems to work,
    you could crontab the commands for your set times.You will first
    have to set the autologin line to "#autologin" this gets the ball rolling
    and is a one time entry.
    then the 4 following commands
    will turn it on and off per your crontab schedule

    22:20 To ON autologin crontab -> echo 'your_password' | sudo -S sed 's/#autologin/autologin/'g /etc/lightdm/lightdm.conf > autologin_on #<-filename
    echo 'your_password' |sudo -S mv autologin_on /etc/lightdm/lightdm.conf
    ? AM To OFF autologin crontab -> echo 'your_password' | sudo -S sed 's/autologin/#autologin/'g /etc/lightdm/lightdm.conf > autologin_off #<-filename
    echo 'your_password' |sudo -S mv autologin_off /etc/lightdm/lightdm.conf
    hope that helps.

    Hi, this should be eaiser to read

    Autologin ON
    Code:
    echo 'your_password' | sudo -S sed 's/#autologin/autologin/'g /etc/lightdm/lightdm.conf > autologin_on
     echo 'your_password' |sudo -S mv autologin_on /etc/lightdm/lightdm.conf
    Autologin OFF
    Code:
    echo 'your_password' | sudo -S sed 's/autologin/#autologin/'g /etc/lightdm/lightdm.conf > autologin_off
     echo 'your_password' |sudo -S mv autologin_off /etc/lightdm/lightdm.conf
    more better?
    *Don't forget to first set autologin line to -> #autologin-user=your_user_name
    and ................................................ -> #autologin-user-timeout=0

    Why are you needing to auto-login anyway? Crontab will work just fine whether you are logged in or not (or do you have an encrypted /home).

    Also putting your password in a script is a very bad idea security wise. The preferred method would be to edit your sudoers file so that the shutdown command can be run without prompting for a password.

    You mean the "download script" will be started from display manager?

    No!

    Editing sudoers list or creating /etc/shutdown.allow file?

    You don't need to be logged on at all for the aria2c program to run, it's a command line program that will quite happily run in the background without anyone logged on to the system.
    I would just have the following entries in your crontab...
    Code:
    00 01 * * * aria2c -c -x16 -s16 -k 1M -m10 --retry-wait=30 -i "/PATH/TO/dl.txt" -d "/PATH/TO/DOWNLOAD_DIRECTORY/" -l dllog --log-level=notice --on-download-complete="sudo shutdown now -h"
    59 05 * * * shutdown now -h
    To set up sudo to allow you to shutdown without needing a password open the terminal and type the following...
    Code:
    EDITOR=nano sudo visudo
    Now add the following line to the bottom of the file...
    Code:
    username ALL=(ALL) NOPASSWD: /sbin/shutdown
    replacing username with your actual username. Save the file and exit and you're good to go.
