preserve changes (persistent mode)

Saturday, July 24th, 2010

This tool at “pendrivelinux” – looks to be a tool that will help resolve the persistent-mode (preserve changes) – on USB-Linux-OS(s), … (follow the link below)

http://www.pendrivelinux.com/casper-rw-creator-make-a-persistent-file-from-windows/

There is a number of other article(s) here on this topic – (Read and follow the tools required to do what you need)

The post might seem a little “Lacking explaination” – but I dont really have time to fillin all the details – (AND; I do NOT have to time to test and document, any of these things here)

Just like to post the links here for later reference when I MIGHT (Have the time) and, .. want to get back into testing USB-Linux operating systems – (more than likely, .. ? YES!)

Adobe plugin installed – (Browser – Iceweasel in Knoppix 6.2)

Friday, June 25th, 2010

CHANGED WRITE PERMISSION(s) –

SENARIO = THIS; – Needed permissions to “Write-Files” into the plugins directory.

This browser (Iceweasel), ..  is some derivative from the Firefox stable. And it is the default browser with this distro.

The default behaviour, where it reverts to its original-state after shut-down -/- reboot, .. deletes any files left on the desktop, and removes all browser shortcuts and history.

I had previously confirmed the correct file -/- plugin required to make youtube-videos play, .. using the Linux Firefox ver 3.6.3. Once this file (libflashplayer.so) was copied into the plugins directory, and restarted the browser, .. youtube-videos play. This browser was installed onto a separate harddisk mounted in the docking-station, .. and so now, always available.

BELOW – The sequence of commands used – (after; su – ) to allow me to write ‘a file’ into the plugins directory (NON persistent version of Knoppix on usb-stick)

Finally got it to work! – ADDED – (permissions) ugo+w to the target directory. Actual command typed out below -

chmod o+w /usr/lib/iceweasel/plugins
chmod g+w /usr/lib/iceweasel/plugins
chmod u+w /usr/lib/iceweasel/plugins

There might be a short-cut to do “All-three” of these in one-go.
AFTER completing the adding of permissions in this manner, …
I was able to copy and paste the iceweasel-plugin required into this directory. (libflashplayer.so) – All that is required to make the youtube videos play.

While some of the webpages are still in the History of this browser, (I will list them quickly below)

#1: – http://www.elated.com/articles/understanding-permissions/
#2: – http://catcode.com/teachmod/index.html

UPDATE: – (Repeating this process will reinforce what has been learnt) – the screen-dump below shows only the command used to complete the “permission-changes” required to allow writing to the plugins directory.

chmod

Some other notes taken from youtube video on basic permissions (pasted below)

The GUI – Hide(s) the permission(‘s)
Most graphical tools hide the detail.

ls -l
ls -ld

Displays the permissions of the directory

ls -l .

Lists the content of the directory
. dot means the current directory.

+++ +++

THREE-IDEA(s)

#1: – Users,
#2: – Group,
#3: – Others,

OTHER NOTES
The tutorials focus on setting permissions on “a-File” – where-as I am wanting to set permissions on the actual directory.

I will have to repeat this process -(every reboot) – for this usb-distro Knoppix 6.2 ~

HENCE; – Need to learn about the next topic called >>> Preserve changes or Revert on Shutdown <<< – which, … requires some definition of exactly what this means. (New post required here, – as this is getting right-off the original ‘post-topic’) – (A link will be added soon for topic “Preserve Changes or Revert on Shutdown”)

FireTorrent 2.0.1 (add-on)

Wednesday, June 23rd, 2010

Installed the firefox addon called “FireTorrent 2.01″ – (to download Xubuntu-iso >>> xubuntu-10.04-desktop-i386.iso <<<)

Currently using Knoppix 6.2 – but figuring out HOW to install “a” torrent-client, was harder than it sounds, .. so I searched on the Firefox-Addons for bit-torrent clients, … install the addon, … and downloaded xubuntu.

+++ Just want to note some url(s) for later reference +++

#1: – http://lxde.org/

#2: – http://www.xfce.org/download/distros

"Xfce is a lightweight desktop environment for various *NIX systems. Designed for productivity, it loads and executes applications fast, while conserving system resources." - Olivier Fourdan, creator of Xfce Xfce 4.6 embodies the traditional UNIX philosophy of modularity and re-usability.

SmartBase MP360, MP370, MP390
MultiPASS PIXMA MP760, PIXMA MP780

Something about needing libusb -???- sane-usb.man – (./configure  -&- Make-work tomorrow)

UPDATED: – [Start-Time = 1:15pm sunday] – After having a little think about what needs to be done, … I have opened the synaptic-package-manager, … and SEARCHED on the term “libusb-dev” – which is available, an marked for installation. (All done) – now the instructions provided by http://mp610.blogspot.com can be completed.

UPDATED: – [FINISHED - 2:15pm sunday] – Managed to complete all the installation instructions, .. running the command $ xsane – tells me access-denied – (That bit of the instructions says copy and rename file “XX-libsane.rules” – The files on my system are named “70-persistent-rules-net” – and I dont understand HOW to set permissions (yet) – … something for me to figure out. – (Might see IF I can run it from the admin-account, just to test the actual driver installed correctly)

UPDATED: – [TESTING -/- CONFIRMED WORKING - 3:15pm ] – Ie; -  “Canon MX700 Sanner” is working now – (Usng sudo xsane) – which, as it turns out is VERY disapproved of, … (sudo =  using the administrator account in M$-windows)

YOU ARE ALONE

You try to run XSane as ROOT, that really is DANGEROUS!

!!! – Do not send any bug reports when you have any problems while running XSane as root: YOU ARE ALONE!

10+ mistakes Linux newbies make

10+ mistakes Linux newbies make

Here’s a look at the most common Linux desktop mistakes by new users. Avoiding these pitfalls can prevent a lot of frustration.

THATS-GREAT; – (Just copied and pasted the image-and-text, from google-Chrome, into this post open in Firefox) – and it will be published exactly as is, without any further formatting from me.
 Opps spoke to soon, … I want the link to open in another window, AND, the font is way to small.

This article, managed to keep my attention, and I actually read the whole article from start to finish (Including ALL the comments), .. that is most uncommon for me.

BT4

Thursday, May 27th, 2010

I have spat the dummy with Vista -/- Lenovo -/- Crapware -/- Adobe-Reader -/- BROWSER – App-Crash-HANG, .. (What-ever the problem – it is NOT fixed – and persists – GRRRRRR -

Writing this from BT4 – (Back-Track Ver4) – (USB-Key installation of Linux Distro)
THIS-POST; – Is going to look VERY rough! – (Some browser feature like Java is missing -AND- Adobe plugins still required for the “Out of the Box” install of BT4)

Booted into BT4 – (Command-Line?) omg – ok – “startx” – (Starts the GUI)
AFTER; – getting into the graphical interface – (Connect to the Internet?) -

Services | Network | Start Network – (They really have made this easy for the new-comer) – Via Firefox Ver 3.0.15

Had to figure out HOW to mount, (any drive) – LIKE – The laptop HDD -OR- external HDD with backup files.

mkdir /mnt/usb2
mount /dev/sda2  /mnt/usb2
Which has given me access Via the Konqueror-Browser

UPDATED – Sunday 20 June 2010 – Found the Ubuntu-Mount/USB instructions HERE >>> https://help.ubuntu.com/community/Mount/USB <<<

MORE >>> About mounting file-systems and Harddisks – Search “Tech Anvil” on YouTube, … (This guy provides a NICE short demo / tutorial using ANY linux-distro to mount-stuff, … { Embed-video below } – HERE it is >>>

Damn – All sorts of stuff is NOT working – so the instructions above can NOT be completed right now, … So here is the url to visit on YouTube – >>> http://www.youtube.com/watch?v=fqhEpvhZ4ck = Tech Anvil <<< – That will be interesting to see exactly WHAT is requried to make “normallity-return” using firefox on BT4

5:55pm – All sorted – The BT4-Team have a Firefox-Addon called NoScript.net – built into the browser – as installed out of to the box, which blocks-scripts.

Had to reset the password on the blog.

Text-Editor-Kate; – (Very nice editor) – I could get used to this!

XXXX – X = OBSERVATION – WordPress-Interface is displaying the pTAG for (paragraph) – XXXX – Checking the blockquote tags work? – Answer = YES – which provides SOME control of the formatting

SAVED-DRAFT – (just messed up the NICE formatting that WAS displayed BEFORE the save)

AFTER a forced interruption like THIS, it is difficult to resume WHERE I left off, I dont even feel like reading it now, … I am going for a walk!

BELOW: – The sequence of text “Vista-Related” -AND- saved into notepad, … that FORCED the “Change of OS to BT4″ – considering it is now 4pm – I am happy to get THIS far, and be able to complete this post :) -

WTF – Now() 2:15pm Thursday 27 May 2010 – Three browsers NOT connecting to the Internet!

SITES; – Attempted to open, BUT – The “App-Crash-/-Hang”-PROBLEM still exists.

SENARIO: -
Have made Chrome the DEFAULT-Browser, … AND – there is 15-Tabbed Pages open

AND; – Outlook 2007, Word-2007, Windows-Explorer, 3-Notepad-Files, …

AND; – Outlook can still send and receive “Test-Emails” -/- Just the browser(s) can NOT connect.
Tried, IE8, Firefox-3.6.3, Chrome being the default browser.

PREVIOUSLY – IF Firefox was to HANG, … I was able to open the alternative browser, and continue, … WITHOUT having to REBOOT.

NOW() – The three-browser (listed above) display NOTHING.

The Lenovo-Vista-Crapware-Abobe-COMBINATION, seems to Fail for me, and the Event-Viewer, (eventvwr.exe), … WHAT does it tell me?

PAGES NOT VISITED; – (Might revisit soon) – { Section Links ~ CUT / Deleted }
Might have to FORCE myself to start using the USB-Linux – (Knoppix 6.3) – As to date the problem continues to exist, making ME, post into notepad, … what you see above! GRRRRR – 2:20pm Thursday 27 May 2010 -

It really disrupts ANY “Workflow” that MIGHT have existed! – Rebooted, back into Knoppix, … That will teach it! – But I want to post-THIS into my GRD/blog, … once I boot into knoppix, … BACKUP – AND – Not the localREF-PATHinfo – *uc* – So I have Two copies – (Gotta be able to access one of them from Knoppix)
xxxxx\C:\Users\grdanson\Documents\2010\ERRORs\AcroRd32_exe\ { 3_NoBrowsersConnect.txt }

TIME – 2:25pm – Backup to external HDD! – Starts NOW()

I will have to FIND the Knoppix usb (asap) – but for now BT4 will suffice! – FINISHED 4:15pm Thursday 27 May – AND – There are four comments to respond to – I have approved those, but will get back to the “reponding-bit” tonight, .. Thanks for the comments -

Calendar Start Date

Sunday, February 7th, 2010

Modem / Router – Have a ‘calendar-start-date’ (Jan 1 1970)

CONCEPT: ‘Date-Handling’

EXTENDED: date handling on machines in the world today

QUOTE: [From url; http://www.2038bug.com/] “Most programs work out their dates from a perpetual second counter – 86400 seconds per day counting from Jan 1 1970″.

A LITTLE BIT MORE; (Text pasted below from url 2038-Bug, all adds up to a more-complete picture – THIS provides a information about WHY my 1st DLink modem and router, contained the 1970′s date, which is a start-point, LIKE ‘as if time started here‘)

Of course we now know that the prevalence of computers that would fail because of this error was greatly exaggerated by the media. Computer scientists were generally aware that most machines would continue operating as usual through the century turnover, with the worst result being an incorrect date. This prediction withstood through to the new millennium. Affected systems were tested and corrected in time, although the correction and verification of those systems was monumentally expensive.

There are however several other problems with date handling on machines in the world today. Some are less prevalent than others, but it is true that almost all computers suffer from one critical limitation. Most programs work out their dates from a perpetual second counter – 86400 seconds per day counting from Jan 1 1970.

Knoppix 6.2 ~ is fun!

Sunday, January 3rd, 2010

Installed pendrive version of knoppix-6.2 onto 4GB USB stick – Everything required just works. NOTE; Need Administrator permissions to successfully install to a usb stick

Setup Internet connection, (Not to hard – if you have the ISP / DNS ip numbers)

TESTED on older hardware HP – D530 mobo

Open Office 3, starts QUICKLY, .. most impressed. Will be using it again soon.

Downloaded Knoppix 6.2 from pendrivelinux

The distro is provided as an ISO file – and there is a installer file – USB-Installer-For-Knoppix6.2-v0.2.exe – which installs the OS to the USB without any fuss, just point the installer to the downloaded ISO file, and provide a path to the blank USB stick and thats it.

Some development information on wikipedia about ‘ADRIANE’ (development started around Jan-09, and Knoppix-Ver 6.2 / ADRIANE 1.2 released 18 November 2009)

The KNOPPIX 6.0.1 / ADRIANE 1.1 is a CD-edition again, and a complete rebuild from scratch. LXDE as default desktop and a very reduced software collection in order to easily fit on CD.

Adriane Knoppix is a variation that is intended for blind and visually impaired people, which can be used entirely without vision oriented output devices.

This review by Dmitri Popov provides a nice overview (If anybody is interested)

Carriage Return -/- Linefeed

Wednesday, November 25th, 2009

Carriage Return / Linefeed = CR/LF

These terms also have a number of different / other ways of being programmed, .. (And depending upon the angle it is being approached – they have different usage, Ie Web-Design, Vs System applications Programming.

Below is some links found connected with GOOGLING this term – CR+LF

#1: http://mc-computing.com/languages/CR_LF.htm

#2: http://www.websiterepairguy.com/articles/os/crlf.html

#3: http://www.acunetix.com/websitesecurity/crlf-injection.htm

That seems to provide enough information to satisfy what CR+LF is – (In terms of coding #1 – defines simply HOW cr/lf is coded) – There is not a comprehensive history about how all this came about. (Might add some more to this later) – The #2: Link does touch on the History very briefly, however is not indepth or definitive.

HISTORY OF CR/LF; Visit ~

#4: http://en.wikipedia.org/wiki/Newline

#5: http://www.rfc-editor.org/EOLstory.txt

NUMBER 5 (#5 – ab0ve) – Very Interesting (If your into this sort of thing) – I have pasted the first two paragraphs below – as this explains in part, EVERYTHING that I wanted to know.

The End-of-Line Story

The ASCII standard for text does not define a unique end-of-line (EOL)
character.  Instead, ASCII defines two independent and orthogonal
movements of the print head: Carriage Return (CR) and Line Feed (LF).
(IBM's EBCDIC did not make this mistake; it defined a single New Line
(NL) character.)  Early operating system designers had to adopt some
"end-of-line" convention using CR and LF; some used LF, some used
CR, and some used a two-octet sequence: LF CR or CR LF.

During the early ARPAnet research days (~1970-1972), this end-of-line
diversity among operating systems made network communication between
diverse host systems difficult.  After some discussion (recorded in
early RFCs), the researchers adopted a single convention:

	ASCII text transmitted across the network *must* use the
	two-character sequence:  CR LF.

The complete page is NOT very big, and well worth a read – (Think Ill go read it NOW!)
