Hardware :: Protected - Sr0 Partition Does Not Get Removed?
Jun 9, 2011
I have an 4 GB USB Drive that bugs me. When I insert it, the fallowing device maps are created in /dev.
1: sdb
2: sdb1
3: sr0
The sr0 is registered as an Optical Disk that I can't remove for some reason. I have tried providing sdb with an new empty partition table, but the sr0 partition does not get removed by this. I think it's something created by some Live Linux CD I may have put on the disk at some point. The label is named "U3 System" and it contains the files "LaunchPad.zip" and "LaunchU3.exe".

My set up is a dual boot between windows 7 and ubuntu 10.04. This laptop used to have vista on it. See image below for my partition set up. pretty obvious where ubuntu should be.I accidentally selected the wrong entry in grub and booted into an acer windows recovery partition. despite exiting as soon as it loaded, the long story short is that it has goodbyed linux.On booting i now just get a grub rescue prompt.I have eventually managed to boot into a liveUSB (cd drive is botched too )As you can see from the screenpic, testdisk shows linux is still there but there are quite a few entries from the upgrades.So, if i can restore the partition around this linux partition will grub come back with it and will all be merry?
I havent mounted any volumes on the drive yet, but i think i need to back up my data before messing with the partition table. is it cool to mount them to pull some data off?general advice for how to proceed would be great.Im not too hung up on keeping the linux install itself. whats gunna be easier? install into that 16gb space and then re add windows to grub, or try and recover this partition?

I have this project for my operating systems class and I have put together the basic flow chart to aid me in writing the program. I know how to use pipes as a buffer to hold info. I know how to create a binary semaphore. But what I dont know is this:
How to "use a delay adjustment parameter K in the critical section to adjust the speed of the display process to show that without semaphore protection the displayed contents of the buffer are randomly interleaved."
First off, I am definitely not asking anyone to give me the solution. But I do need some guidance. So I figure there will be an if statement with two options:
1. If true, use semaphore protection to enter/exit critical section
2. If false, no semaphore protection -- this is where the contents of the buffer should be interleaved.
Now does that mean that as each child process enters the non-protected critical section, it should "sleep" for a randomized time? I mean, will this allow my output to be interleaved?
So lets say my command line looks like this:
what happens to the 100? Is it randomized using rand and srand and passed as a parameter to sleep() inside the critcal section?

This is sort of a weird question.'m helping an agency develop a Microsoft Access database. They use windows and I use Fedora. I can run Access in Crossover Office if I don't get too fancy.I've sent what I've done to them for their review and comments and somehow it has become password protected. I've checked the Access settings and their is no password set from Access. I've tried a chmod666 on the file and sent it to him again and he says it is still calling for a password

I am trying to copy a (custom XML) file to a protected folder (namely /usr/share/games/FlightGear/Protocol) for data Input/Output.I tried copying and pasting the folders and it doesn't work. I realized that it is because only root user has the permission to do modification.So, I tried using "sudo cp" to copy the file. The file was copied, but the content now becomes unreadable when I tried to open the file

I just purchased an AirLink101 AR670W wireless router and it works just fine, states on the box that it works for all Microsoft Windows, Mac and Linux, but cannot get the CD to work, it comes up with a box that states cannot find the path in Archive manager. Without this cd I cannot use the software to put on WPS wifi protected set up, or the Nat+Spi firewall.I checked the manufacturers website and all it states is how tose the software in MS Windows. I have the latest version of Ubuntu which I think is 11.04

I like to make iso backups of my disc. I was going through some game cds that I have not backed up yet. I want to stress I DO OWN THE DISC. I just want to make an iso backup of the disc just in case something happens to them.
I normally use dd to backup my disc to an iso. Typically I use this command
Code:
dd if=/dev/sr0 of=someimagesname.iso bs=2048 count=1234567
I always replace the numbers for count with whatever the volume size is when i run isoinfo -d -i /dev/sr0. However I have a few game cds that I can not back up. I have tried 3 different disk that have this issue. I think they are all copy protected.
I am trying to backup the following disc:
Microsoft Rise of Nations
Sid Meier's Civilization 4 Warlords
Microsoft Empire Earth 3
When I dd any of these disc I get an iso that is 1.7GB and is not a valid iso image.
I was however able to back up other disc. How can I make an iso backup of the copy protected disc?
I would like to stress I do not condone pirating and I understand that some people may think this post is related to piracy. I simply want to make a backup of a disc that I have legally purchased

I have a bash script that will unencrypt a file, use the unencrypted file for a very short time and then delete the unencrypted file. The problem is that my password is in clear text
[code]...
Obviously this isn't so secure, but I need the script to be non-interactive. How do I hash, encrypt or otherwise make secure the password for the openssl command? I know that the openssl can protect passwords, e.g.:
openssl passwd -crypt "password"
But can I use this protected password in my script?

Each time I try to just open a password protected archive with Ark it just shows a "Loading file" progress bar, but nothing happens after several minutes. And if I just right-click and select "extract" extracts nothing. It doesn't even ask for the password at any moment. I also checked the help typing "man Ark" in the console, but found nothing related to passwords. Has someone successfully opened archives with password with Ark? Or is it still buggy?
And on a side note, I can open normal .rar files, but cannot compress files. It says "failed to locate program RAR in the PATH". I thought Ark was all self-contained. Do I need to install something else?

I'm running opensuse 11.2 on a Dell laptop with a intel wifi card.
I'm at a hotel with wireless protected by the MAC address. My MAC address is already registered and allowed to connect. However when I connect, the connection hangs just a few minutes and I got disconnected.
I tried to id some problem by scanning it with wireshark, but I did not found anything.
I wonder if there's some kind of MDNS problem...

i have 2 users on my login window.one of them is password protected, the other is just a single click to login.
1) how can i get the password protected user to disappear but show up under certain circumstances. like, some soft of hidden key combination or the like?
Getting this done isint as important as the second part though
2) when a user logs in, what happens? What file gets executed to start the login processes? I want to know because i would like to make one of the users a guest account that removes all changes upon logoff.
