comment Difficulty with mobile broadband device being recognized (registered as CD ROM)
for testing usb_modeswitch I got "searching for target devices ... Found correct target device ... Mode switch succeeded. Bye." so I proceeded with the further steps. I tried betavine again but still it did not detect a device, and in the connection manager the device is not listed. I ran usb_modeswitch -e to get the version and it says: "* Version 1.1.0 (C) Josua Dietze 2010 * Based on libusb 0.1.12". So I should update this and how because the synaptic package manager has only this version? and how do I find the exact 3g-modem it is?

comment Difficulty with mobile broadband device being recognized (registered as CD ROM)
from your link that you added to set up the modem in Ubuntu, when it asks to run "ls -la /dev/ttyU*" I get no files under this expression. And when running "sudo wdialconf /etc/wvdial.conf" it says that it scans ports for a modem but then it says that no modem was detected. I have tried all avenues I can see, is there any further direction?

I made a live usb of Ubuntu 10.10, and booted up the system, and it did not work. I tried sakis3G on it as well, and it still failed to connect. I will try the information given on the link you added in your update.

on the Desktop icon it is shown as VMB_10.2.102.30707_RP171 but this name is not listed anywhere on the net or in the known hardware list of usb_modeswitch, how else can I find the name if it is named otherwise actually? I think that usb_modeswitch should be installed properly since the man pages work and sakis3g should have installed it again if there was a problem (likewise for betavine). I tried unmounting to see if it appears in the list but it does not in the end. I will try the live CD approach. Should I try even newer maybe? (just to be sure?)

@psusi, that is a good thought, so do you insinuate that this was done deliberately? Because the device is provided by Vodafone which do say that they support Linux, and do facilitate the Betavine project which supplies many drivers for these mobile broadband devices. I am hoping that this particular device is not one of the few which are made to work only under windows with the current software available.

comment How to understand the filesystem concepts used by encfs?
very nice answer, and really clear. Would my layman interpretation be correct to say; "the un-encrypted file is only stored in memory, not on disk, and this in memory file view is presented by encfs while using the key, and the encrypted file on disk was created from the original file using the key given"?

comment How to understand the filesystem concepts used by encfs?
so 1)the encfs filesystem is something that uses the number 5 in a way to get back 123456? 2)If so, why is this called a file system and not something like a proxy, or file interface? A filesystem to me sounds much more grand and general purpose than an algorithm to get back the original order of the data. (thank you for you time:)

comment How to understand the filesystem concepts used by encfs?
I am still struggling with trying to create a pictorial representation of the mechanics in question 1. Would you please provide any step-by-step walk through the process? I have a confusion possibly because I picture a file unencrypted and when encfs encrypts it through the algorithm, the bits are rearranged in a way which makes it unreadable. How is it actually done?

That is an amazing explanation. I feel like I learned alot. And the extra links help. So the filesystem made by encfs is 'jumbled up blocks of the original file' and through encfs you can navigate and read it; because the original filesystem is not compatible to use these blocks of data. and the encrypted directory is hidden to not get into it by accident. and if you did you would see nothing?

the answer is very useful and practical. I would appreciate very much if you could add some more text to explain what each operation is doing if that is not a bother to you. And could you explain what is meant by a filesystem in this context, and the relevance of mounting?

@bdowning, yes, you articulated it correctly. I do not understand filesystems and their operation. I would work blindly with the commands without understanding the concepts.

@FaheemMitha, I also would like to avoid the filesystem route, it sounds complicated.

creating a new file and deleting previous is a .zip route with password protection. I don't understand the file system and mounting route you refer to. Is there not some program which jumbles up the file in some way and then can put it back into order?
