Downloading extensions without appbrowser access.

[Jason W]

As some folks have boxes that are wireless only or require funky firmware to reach the network, they may need a basic set of extensions installed before they are able to configure a network connection with the standard TC iso boot so as to allow appbrowser access.  So here is a script that allows the easy setting up of a tce directory from within another running distro that is network enabled.

The script is to be run without arguments.  Asks for 3 things.  It prompts for a desired mounted partition where the tce directory will be created.  Then you specify for either 32 or 64 bit Tinycore.  And then prompts for an extension to download, which will download the extension plus dependencies, entering the main extension into the onboot.lst file, and then prompting if another extension download is desired.  It stays simple, sticks with the name tce for the tce directory, and onboot.lst is populated to boot the selections and their deps.  Once booted into the perhaps graphical TC with extensions and then a network connection established, the standard TC tools are to be used to manage the tce directory installation.  

This script simply requires that GNU wget is installed.

EDIT: Removed use of zsync as Debian stable's version is too old to work with our zsync files.

But do not use it on a running tce directory that is in use.

Example use, answers are in bold:

-----------------------

(Make sure and run as root)

root@box:# ./filltcedir
 
Enter mounted partition you would like your tce directory to reside on.  Example: /mnt/hda2   /mnt/hdb1
 
Enter the name of the extension you would like to download the your tce directory, deps will be included.   file.tcz
 
Fetching file.tcz...
 
 
Would you like to fetch more extensions?   n

Fixed  a critical kernel version bug.

[Jason W]

There has been some interest in being able to do this from within Windows, so this has been adapted for use with Cygwin running under Windows.   Just install the "full" version of Cygwin to give you all the normal Unix commands.  Also, install Windows version of Wget with the "Install" option so it gets installed to it's normal Windows path.  Then in Firefox, download this script attachment, which will put it in your "Downloads" directory.  Then launch Cygwin from it's desktop icon.  Then use these specific commands if making a tce directory on the main C: drive:

$ chmod +x /cygdrive/c/Documents\ and\ Settings/$USER/My\ Documents/Downloads/filltcedir

$ /cygdrive/c/Documents\ and\ Settings/$USER/My\ Documents/Downloads/filltcedir

Then just answer the questions. 

To use drive C:, enter without quotes "/cygdrive/c" as the mounted partition to place your tce directory on in the first question.


As to the drive letters, I have tested this under my fat32 C: drive, as well as ext2 formatted drives using an ext2 driver.  The ext2 driver I had best use with is this one:  www.ext2fsd.com    Just set it up per instructions to use an ext2 formatted drive or usb key.    If using drive F: for example, then obviously use the letter f instead of c in that first question:  (/cygdrive/f    instead of   /cygdrive/c).

This script simply requires that GNU wget is installed.

Note on running the script in TC-Enviroment:

The script requires the extensions for "wget" and "grep" (busybox versions are not enough).

[Jason W]

Thanks, worth noting even if the intended use is on a non-TC machine. 

[Patatalo]

I go here: http://ftp.vim.org/metalab/distributions/tinycorelinux/3.x/tcz/

download every tcz you want and mount them with "mount file.tcz /mnt -o loop". I think a tcz is a squashfs file.

With the advent of the starter packs that are for gaining network access, this script will now be unmaintained as no longer really needed.

[tinypoodle]

With the advent of the starter packs that are for gaining network access, this script will now be unmaintained as no longer really needed.

Hmm, there might still be a potential need in cases where the only way to connect would not be covered by starter pack, e.g. out of kernel or staging wifi, dial-up, cellphone modems.

[Jason W]

True, and it would be fairly trivial to maintain and keep current.  But I promote the use of the new starter packs above using this script.

If a script is needed to download existing extensions in the repo that will provide for a the ability to set up a connection after those extensions are downloaded and set up in a tce directory, then I am sure those extensions are candidates for inclusion in a starter pack.
