    HOW TO: Start Kali with a new unique hostname for each boot

    Given the popularity of this distro, seeing a computer named "kali" on a netowrk may raise a red flag. So, here is a way to avoid appearing as such:

    To get situated, open a terminal and cd to your root directory:
    Code:
    cd ~
    STEP 1: Create a script which will automate the procedure

    In this terminal create a file.
    Code:
    touch newhostname
    leafpad newhostname
    Now, add the following lines to your newly created file:
    Code:
    #!/bin/bash
    
    cp -n /etc/hosts{,.old}
    
    newhn=$(cat /dev/urandom | tr -dc 'A-Za-z' | head -c8)
    echo $newhn > /etc/hostname
    
    echo "127.0.0.1    localhost" > /etc/hosts
    echo "127.0.0.1    $newhn" >> /etc/hosts
    cat /etc/hosts.old >> /etc/hosts
    service hostname.sh stop
    sleep 1
    service hostname.sh start
    xhost +$newhn
    exit
    Save it and exit leafpad.

    STEP 3: Make it run at boot
    Store it:
    Code:
    mv newhostname /usr/bin/newhostname
    Make it executable
    Code:
    chmod +x /usr/bin/newhostname

    Make it run at startup:

    --Click on "Applications" --> "System Tools" --> "Preferences" --> "Startup Applications"
    --Click "Add"
    --Fill in:
    ----Name: New Host Name
    ----Command: /usr/bin/newhostname
    ----Comment: Start Kali with a different hostname each boot

    Nice Idea

    Have taken all steps as described but for me it does not work.
    The symlinks in rc2.d to rc5.d are also different to the "normal" system symlinks
    The "system" symlinks...
    0 lrwxrwxrwx 1 root root 20 Jun 17 04:40 S19pulseaudio -> ../init.d/pulseaudio
    0 lrwxrwxrwx 1 root root 18 Jun 17 04:40 S20bootlogs -> ../init.d/bootlogs
    0 lrwxrwxrwx 1 root root 18 Jun 17 04:40 S21rc.local -> ../init.d/rc.local
    0 lrwxrwxrwx 1 root root 19 Jun 17 04:40 S21rmnologin -> ../init.d/rmnologin
    And the symlinks of the loop
    0 lrwxrwxrwx 1 root root 23 Jun 17 07:10 S27newhostname -> /etc/init.d/newhostname
    I've tried to change /etc/init.d/ to .. /init.d/ but it will end in a "File dosent exist" error...

    Do you have any advice what I can do?

    P.S
    sorry if something was not easy to understand my english is not really good
    but i will try my best

    Apparently an update changed how startup scripts are run. Here, do this:

    Code:
    for i in {2..5}; do rm /etc/rc"$i".d/S27newhostname; done
    rm /etc/init.d/newhostname
    Then follow the modified steps found in the original post now. This should work, but I'll update the post with something cleaner soon.

    If you do it like I did, over ssh to a headless raspberry pi...
    You can do this to start the script..

    mv newhostname /etc/init.d/

    update-rc.d newhostname defaults 100


    Now reboot your computer...
    After that you should see for exemple : user@xRxAebQc

    Thanx for me ..
