View Full Version : [ubuntu] What can and can't be done???

Apparently my computer is acting with dual personality.
I'm not sure what technology is available today compared to what
was claimed in the movie "Enemy of the State."

I have seen my USB drive indicate less disk space than it really has.
And none of my optical drives seem to write data.
I am running on Live CD with no hard drives connected.

It appears if I try to boot Ubuntu with my ethernet cable tethered,
sometimes the boot fails. So now I only boot without the ethernet cable connected.

Is it possible that my motherboard could have been switched out with a hacked up one which can be remotely controlled?

No, not at all :)

You need software to be able to do that, and if you're running without a Hard Drive, that would be incredibly hard to do.

Okay, For the USB drive, how much less?

Not sure about the optical drives, but how does the boot fail with ethernet.

I highly doubt that your motherboard was replaced.

A sidebar theory, which I hope is not a possibility.

Based on info released to public so far, our phone records are in the hands of people who are trying to protect us from a war without an enemy that we know of, in advance, anyway.

What's troubling is that peoples phone records are all located in a common reserve where a computer program can do what ever with it.

Theoretically everyone is six degrees of separation from everyone else socially.

With access to ubiquitous amounts of phone records, in theory a map of social relationships can be developed, where everyone who knows someone knows someone and so on.

Lets say someone who is inside Ubuntu development is being sought after by someone who needs that person's expertise.

Theoretically that person can be reached through a chain of social influences.

Now the thing that I'm hoping is not happening is can someone very knowledgeable in Ubuntu linux make a person's computer like mine become remotely controllable, assuming in theory?

What type of tin foil are you using for your hat?

Dude, I seriously doubt you are being "remotely controlled". If you don't want to get help, don't post.

The USB drive has 1Gig from factory.
I put about 100 meg of data on it.

Yesterday when I tried downloading the Ubuntu iso image
the download kept failing because I did not have enough space.

So I figured that I try using the USB drive for storage.

I checked the USB drive properties and the available space was less than 400 meg. I realized here something didn't add up.

The Ubuntu iso image download failed multiple times at around 300 meg.
Furthermore I can't seem to specify the USB drive for save to disk.


I guess there can be an answer for everything.

But I have some reservations about the negative reflections on my postings already.
I am looking for information here.

I have seen my USB drive indicate less disk space than it really has.

Often this is more related to false advertisement of the producer. One gigabyte should be 1024x1024x1024 = 1073741824 bytes, but producers are telling us that is 1.07GB. So according the strange reasoning of the advertisement department my 80GB portable HDD is actually 74.5GB according the computer system. :mad:

Can't you browse the files on the USB to see what is on there?

halitech
July 29th, 2008, 05:03 PM
in a terminal, if you do
df -h it should show you the main folders and how much are used and how much is available. One thing I learned is that if you delete something on a flash drive, it gets moved to the trash on the device so you may need to use Nautilus and enable viewing all files and delete the files from the .trash folder (if any are there)

By the way I have another computer which I have placed a lock on since purchase. And the optical drives seem to work there, along with the USB drive showing more closely the available disk space. I pretty much use Ubuntu Live CD without a hard drive.

My other computer is a Vista packaged PC which I disconnected the hard drive.

I boot with Ubuntu on it. And I have not yet connected to the internet with it.

By the way I use Ubuntu 6.10 and the video, lan and sound drivers don't work with this PC. It seems Asus, Nvidia, and ALC has a deal with microsoft to not allow drivers to be downloaded for linux users.

ok, so it is being seen as a 1gig drive but after formatting it brings it down to 954 and you have used 525 meg of the available space

you may want to consider updating to 7.10 or 8.04 as they will have better support then 6.10 does as it is an older (almost to the non supported state by Canocal) which hopefully will allow you to get all those devices working.

far as your video card, Nvidia has always been the card of choice for linux users as it has always been supportive of open source.

According to data on my USB drive I have 62.8 meg of files.
On a 1 Gig drive I would expect a little bit more free space.
I checked on my other computer as well and now the free space is the same at 430 meg.

Something still does not add up.

Did someone put data on my USB that I can't see?

linuxrus1
July 29th, 2008, 05:39 PM
I appreciate your recommendation to upgrade to newer version.
But I can't seem to get the download to work.
I have submitted a request for a free CD.

Type: folder

Contents: 87 items, totaling 62.9 MB

Location: on the desktop

Free space: 429.2 MB

Interestingly my other computer had 62.8 MB.

open the drive with Nautilus and press
CTRL Hthat will show you the hidden files. look for a folder called .Trash (the . is important) and see if you have files in there. If you do, they are hidden and thats why they don't show up and make it look like only 62.8meg is used. Depending on the ownership of the files, you may be able to delete them from there (press down the shift key and it will delete them completely). If not, you will need to open Nautilus as sudo


gksu nautilus
and then you can delete them

July 29th, 2008, 05:59 PM
I found .Trash-ubuntu folder with a couple of files.

I removed them via rm -r .Trash-ubuntu.

I still have a lot of missing free space.

I can't find any hidden files.

I do remember copying the partial download of the Ubuntu iso file on to the USB drive, but I had deleted that file.

As for the USB drive mysterious free space loss,
I just decided to remove the visible files off the USB drive and then
reformat the USB drive and then reinsert the visible files back onto the USB drive. I think the formatting got rid of the unkown or missing free space.

July 29th, 2008, 09:40 PM
