Ubuntu :: Data Locked On Second HD?
Nov 8, 2010
I recently had CentOS installed, but felt that I didn't need the whole server thing, so I picked ubuntu as my OS as I have used it in the past and quite liked it. I formated my first hard drive and installed Ubuntu 10.10. My second drive is a ext3 data drive only. After installing Ubuntu, I can see the drive on the desktop, telling me that it is mounted...i think? But when I goto the drive all the folders are protected. I tried to chown with root to see the stuff but to no avail. I can't seem to change permissions on the drive either or the files.

I've been using Excel from OpenOffice with moderate success for the last year. Now I've just tried to open a new spreadsheet and I'm suddenly getting a highly condensed view. The cells are about 1mm X 4mm. If I expand them by selecting and dragging, then try to copy data from another spreadsheet onto the new one, the data shrinks to the small scale -- unreadable.

Right now I have a 320GB system drive and 3TB data drive. I want to add two more 3TB drives and do a software RAID5 3x3TB. Is that possible without losing the data that is already on the data drive?Just want to make sure before I bought the 2 two drives. Not looking for instructions on how to do it,but if you want to include some that would be great too Just making sure it will work.

We purchased a new database system at work last October, ditching the old system because of a lack of support from the vendor. This is a retail Point of Sale and Backoffice database system. I am not sure what system the new one runs on, but the system we replaced was a Firebird data base. The reason I am posting is because we are now in need of the information contained in the old database which was not completely imported into the new system.
Basically the problem is this: The database in on a Windows XP system and I found a copy of SQL Manager Lite 2008 on the system, which after quite a bit of studying, I figured out how to extract the database into a removable file. I have this file (178MB) on a USB stick in a file called Backoffice.fbd.
My studying suggests to me that I can get into this database with MySQL. I have never used this and have no clue how to do this. All I want to be able to do get into the database and create tab deliminated spreadsheet files for each of the database sections (Customers, Repairs, Sales History, stock files, etc.) Is it possible to do this with Ubuntu and MySQL and if so, can expert suggest one or two things to get me started. While a guided tutorial would be nice because I am not an expert, I am willing to learn on my own if someone could point me in the right direction.

Now I find myself locked out of SSH! I have another SSH user and I logged in on him but he doesn't have permission to chown the file back! I also tried using su root -c but it is rejecting my root password as if it is invalid, but I know it is valid! I have 2 root accounts on the system and both return "invalid passwords" ever since I chowned the damn file..Does anyone know what I can do? I am very far from the server I must be able to do it remotely. Maybe a server reboot will help?

Was able to use a dual boot (Windows 7 and Ubuntu Maverick Desktop version) with only minor microphone couldn't be accessed issue. Had the system lockup completely, even power on and power off or Magic AltSysRq combinations does not help. This happened once before but after parking the laptop for a day, it restarted without issue.
Just prior to my shutting the laptop down, response went to a crawl, the system took much longer to shut down but did. Upon restart (and since) the machine just hangs. I do not see the machine on my network.

2.After a year on Lucid 10.04 I installed all updates and did an online upgrade to 10.10 Great!3.Enthusiasm got the better of me and I clicked the upgrade to 11.04. Big mistake.4.I get the 11.04 desktop, but it has no response to mouse clicks. I'm locked out - can't click to log in to my private files.Is all lost? The cursor moves OK and the keyboard works (They are wireless and I guess I'll put on wired ones to eliminate any problem there as I fix stuff.)5.I have never done my own installation or partition work.6.There are a few things I did not back-up, and I'll miss them. Some bookmarks in Firefox may be impossible to ever find again.I really need the Evolution e-mailI dual boot with XP and am now booting up from an old 9.04 disk that I found.I thought I was doing a minor upgrade to Natty 11.04, but the screen tells me I have 2.6.32-32-generic kernel Is there any going back?

Where apart from ~/.kde4/share/apps/kmail does kmail keep account data, such as login data/names of pop/smtp servers? I wanted to install an entirely clean version of kmail, so I uninstalled/re-installed kmail via YAST. I manually deleted ~/.kde4/share/apps/kmail. After installing kmail I found that the account data of my Yahoo account were still listed in the kmail configuration panel. Shall I delete the Yahoo account within kmail prior to uninstalling the kmail package?

Now I have the following problem the LVM file system don't mount properly.If I open the mount point I see only a few files of the LVM disk. If I want to unmount the disk I get the following error:

umount: /data/: not mounted
If I want to mount the volume I get the following error:
mount -a
mount: /dev/mapper/gegevens-Data already mounted or /data busy

I'm trying to connect to the VPN of my employer; after fix various minor issues I reach this point in which the DNS entries and the default gateway of the VPN are overwritten with the values of the eth0 device that appears by default. Therefore the vpn is not useful.

A few minutes ago I accepted a suggestion from update-manager for restarting my system, such that some security updates could be effective. After restarting and login in as usual, I discovered that I could not use my adminstrative rights as a sudoer. To recover them I booted again, as root, and added my username in the "admin" group. Rebooting, all seemed well again. As an extra check I installed and ran 'chkrootkit' and nothing suspect was found.What could have hapenned? Just a glitch in the system? Can a user disappear from a group for nothing?What further checks can I make to be sure that my system is safe?I'm using Ubuntu Jaunty Jakalope amd64, with kernell 2.6.28-15-generic.

Dual boot sys with ubuntu lucid lynx 10.04 on Windows 7 host.I created a dot directory (.rams) yesterday and decided to do a chmod on it. Stupidly,(you can call me a moron) I used the asterisk as a shortcut notation and in effect chmod-ed all the dirs starting with a dot. So when I tried to login, this AM,an error mesg appeared that advised me to change the permissions but I could not get into a console or the desktop. After trying several things on Windows, I simply moved the exisitng ubuntu install into another folder, ran uninstall and re-installed. But is there any way that I can access the sys to undo my stupidity? I have a ton of docs on this install.

I have a rather frustrating issue here that's been giving me hell since about 5:00AM this morning. I just got a new laptop (a Compaq CQ42-138TU) and was hoping to dual boot between Ubuntu 10.04 and Windows 7 Ultimate (64-bit).So, I partitioned the HDD (leaving the HP/Compaq restore partition and other partitions alone) and resized the partition that held the bundled copy of Windows 7 (32-bit). I resized it into two parts, installed Windows 7 Ultimate on one, and Ubuntu on the other. That's where the problems began.Selecting "Windows 7 (loader)" in Grub presented me with the first few second of the bootscreen, then a BSOD for less than a second. After that, the machine immediately rebooted and got back to Grub. Ubuntu still booted fine, but I wanted to get access to Windows back, soI attempted to fix this by running:
Code:
bootec.exe /fixmbr
through CMD.exe on my Windows install disk. Now Grub is gone, and I'm stuck with Windows that still won't

I can't log in from a locked screen anymore, such as when returning fromeep or hibernation. I can, however, work around the problem by clicking "switch user" and logging in from the GDM greeting screen. Logging in from a terminal also works.I recently had a problem where /etc/passwd, /etc/groups and some other files were deleted. But I have restored them - otherwise I couldn't log in at all.

I have a small problem with my Acer netbook (ao521) on which I dual boot windows7/ubuntu. I am new to linux and I didn't know much about dual booting so I made some errors when pratitioning and installing ubuntu (originally I had windows 7 only) but that is another issue.
The problem is that I accidently wiped the /C partition of win7 thereby deleting windows (). I had made a backup since I knew something like this could happen and I saved it in /home so now it is in /home/backup. Here it gets interesting though..I tried recovering Windows (with the built-in Acer eRecovery) and apparently this messed up Grub so I couldn't boot ubuntu..Now, I don't have a problem installing windows from scratch and then installing ubuntu afterwards (I have learned my lesson and I think I would do it right this time), but there is one folder, which contains some valuable documents and I want to access it and save the documents on a USB drive.
So, I ran ubuntu from the live cd(usb) and I mouned the /home partition (of my previous installation) and I tried accessing the backup folder that I made earlier but it said that I do not have such permission. I did some searching arround and I found out that I should mount the partition as root and copy the contents of the folder from the terminal. So far so good, but when I wrote
Code:
sudo mount /dev/sda9
it said that no such mounting point is available in /etc/fstab.
It occured to me that I could use the data in the initial /etc/fstab (from the initial ubuntu installation) and insert what I need in the current fstab. I did that but when I write /home as mounting point it apparently confuses it with the current /home so that doesn't help.
Well my question is: how can I edit fstab so I would be able to mount the partition and use it or is there any other way to access the folder in question.

I have some data files that should be distributed with my program. Using dist_pkgdata_DATA in Makefile.am, I get these files installed to /usr/local/data/share/package-name. The problem is that data is read-only, and my program needs to modify it. Playing with dist_sharedstate_DATA, dist_localstate_DATA, dist-data_DATA varibles, I got different installation directories, like /usr/local/com, usr/local/var, but data is always read-only.
How can I distribute modifiable data files with my package? I need some common directory for all users, or maybe local data in a user directory.

I'm a software engineer that has recently tested our hard drive locking feature; I discovered an issue that prevents the user from removing the hard drive password and I used a lot of drives to narrow the issue down. Is there any Linux utility/command that can unlock drives?
There is a windows based utility here: [URL] but you need to pay to use it. I guess I'm looking for the free Linux equivalent, if there is any. FYI: The Locking is performed at the firmware level of the hard drive so a low format will not unlock it. This is a specific feature most drives have that not a lot of people know about.

About a month ago, I had something go very wrong in my Karmic and my account (with an encrypted home dir) was essentially inaccessible. But I was eventually able to create a new account, and retrieve all my data, but now, for some reason, I cannot edit the 'Startup Applications'.
I open its window and make any changes (which the window seems to accept), but then when I hit close, and restart it, it has been reset to everything I had set from my other account. Which makes little sense.
After that problem, I did have some trouble with permissions of certain files, and am afraid that I inadvertently gave up permissions on my startup applications, but can't imagine what I'd have to do to fix it.some guidance?

With this install the top panel is locked on top, gconf 'locked' checkbox is unlocked.Is this a bug or a feature? can we work around.

I just bumped into somewhat embarassing error, and i cannot find any way to get rid of it. I was installing postgresql-common from the ubuntu repos. The blue configuration box appeared in the terminal i was using (blue configuration tool with the red scrollbar on the right). The thing is, there is nothing i can do with this box (clicking <OK> on the bottom, keybord shortcuts, i tried everything). After a while i just rebooted the terminal and started all over again. I recieved an error "dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem." Running dpkg configure command results in resuming postgresql installation and the blue box of death.
Now the apt-get is useless for all the users on my machine, and 1st core of my CPU is used in 100% all the time. How can i reset the dpkg?

I have recovered most of my USB drive, but a couple of folders are locked and look like files. I'm unable to change permissions on them and "You are not the owner so you cannot change these permissions." appears in the properties tab. The owner is "184444735 - user #-184444735" and the group is "17414907" which makes no sense to me. Most other folders and files are OK. The disaster I recovered from was a partition move that failed. I used fsck to get most things back. Any idea how I get these couple of folders (the most important one is one of them "Documents" of course). to be visible?

Any good ideas for a GUI program that monitors temp for CPU and hard drive? I'd prefer one that is like a system monitor that can show trends on a graph (like CPU usage, etc). It is irritating that you can't even add a silly app to the panel because UNE is locked (ERR, Ubuntu, what were you thinking? Give US the choice! Rant over) So far, I have just written a quick script after installing lm-sensors and hddtemp and run the necessary setup routines that will show me, but I would like some of the history data.
Code:
#! /bin/bash
# zenity --info --title "Temp INFO" --text "sensors"

In Ubuntu 10.04: if the screen has been locked (automatically by the screensaver or user-activated using the top-right menu) pressing the power button doesn't initiate shutdown. Is this a bug or is it a configurable option?I would expect to either get the usual 60 second shutdown delay or a graceful shutdown right away.
