Ubuntu :: Cryptsetup - Cannot Access Device

Feb 23, 2010

I have 10 hotswappable SATA drives I use for a rotating backup system. On each drive I have created an encrypted LUKS partition. I normally mount the drive by first unlocking it via:

Code:

cryptsetup luksOpen /dev/sdc1: BD-4-B

However some time last week this command refused to work...for any of the drive. Before I even get prompted for a password I get the terse error message: "Command failed: Can not access device"I can't recall if it was a system update that broke it, but now I can't get to any of the data on these devices nor can I run any backups.

Debian :: Cryptsetup Automount USB Key

Aug 27, 2015

I setup a luks encrypted /home partition on my Debian jessie, with an automount when my usb key containing the luks secret is plugged in at startup.

I did configure /etc/fstab so that my usb key be mounted at startup to /media/usb1, and /etc/crypttab to open my encrypted partition with the key at /media/usb1/homekey. It works.

However, when my usb key is not plugged in, boot fails and never shows welcome screen. I would change this behaviour so that when my usb is missing, boot resumes and do not mount /home partition. How could I manage this?

Ubuntu Security :: Cryptsetup Won't Accept Password After Normal Reboot?

Feb 2, 2010

Strange thing happend two days ago. I just wanted to reboot my computer and now I'm no longer able to boot o0. My system is runnig with a full encryption with luks/cryptsetup. I'm using a passphrase to unlock my first partition and it will unlock the others by itself. So far so good. But now it doesnt work anymore... I'm not sure what I did before, but what I know, I didn't change anything! about cryptsetup. I did only a little "update" with the recommended packages from the repositories (guess only 4-5 updated)

I already checked with live cd and same thing there. Not able to unlock any device (what seems strange to me, cause there are 4 of them and all corrupted at the same time...?)

I always get the error message: unlock failed, bad password or options? (on boot) Command failed: No key available with this passphrase (live cd)

First thing I did was checking wheter all modules are loaded:

Code:
ubuntu@ubuntu:~$ lsmod
Module Size Used by
sha256_generic 11580 0

Slackware :: LVM/CRYPTSETUP Duplicate Devices In /dev/mapper Again?

Jan 23, 2011

We had this problem a while back but it went away with whatever updates lvm/cryptsetup have been through, but it's back again as of the latest update. Instead of symlinks to the /dev/dm-* devices, lvm and cryptsetup are both creating duplicate device nodes under /dev/mapper for already existing devices.

e.g.
Code:
gazl@slack:~$ ls -l /dev/mapper
total 0
crw------- 1 root root 10, 61 Jan 23 16:48 control
brw-rw-r-- 1 root disk 253, 0 Jan 23 16:48 lukssda5
brw-rw-r-- 1 root disk 253, 9 Jan 23 16:48 rootvg-lvhome

Ubuntu :: Un-Mountable Sony DVD+R/RW DRU540A !?

I can't get Ubuntu to mount my Sony DRU540A, no matter what I do. Audio CDs, Data CDs and burning are impossible, does anybody have any ideas on how to mount this unmountable drive? It worked well enough to install Jaunty Jackalope, and I never had any problems using this drive with windows xp, but now that I've upgraded Karmic Koala it doesn't seem to work no matter what I try.

I've upgraded to the new 10.04, and when I have the Alternate CD in, it shows on my desktop, and I can search all the contents of the CD, so I know it's registering.

Then I click ok and it says it's not mountable, even though I know it is because it's on my desktop.

Ubuntu :: Why Does Plugin-container Use So Much RAM?

Jul 1, 2011

When I use firefox, I accumulate multiple plugin-container processes, typically one of them sits around hanging onto well over 200 MB of RAM. I think this happens when I watch flash videos. Does simply having a flash app on a web page cause a plugin-container process to be created? Will they ever go away without my explicitly killing them or closing firefox? If they stay around, do they ever free any RAM?

Slackware :: 13 2.6.29.6 Cryptsetup Luks Wrong Device Name In /dev/mapper/*?

Mar 3, 2010

Slackware 13 Kernel 2.6.29.6 have three hard drives. Root is on own drive sda1. sdb and sdc are raid via mdadm with two partitions. one for /home raid0 md0 one for swap raid1 md1. md0 is encrypted vi cryptsetup. md1 is encrypted vi fstab. everything boots fine and is accessible. However, /dev/mapper/* shows sda1 as block device connected to the raid md0. swap crypted device is correct in /dev/mapper/*. fstab is set correctly. problem seems to be with initrd. I would like the correct device in /dev/mapper so that I can access drive info; size, available space, etc. now info shows only sda1 info

Ubuntu Installation :: Raid 0 Is Not Mountable After Reboot

Jan 7, 2010

I currently am setting up an htpc running Karmic. The problem I am having is getting my Raid 0 to be mountable. My raid is not my boot partition, but is for data storage. My setup is a zotac motherboard with three sata connectors. I have a 300 GB drive, my eSata port, and my DVD attached to these. In the PCIe expansion slot I have installed Syba 2 port Sata PCIe 1a card using the Sil3132 sata II host chipset. Off of this I have 2 1.5Tib Hdds that I am setting up as Raid 0. During the boot I enter the chipset BIOS and establish this as a Raid 0.

When I install Karmic it sees the Raid and my 300 GB drive so I install to the 300 GB Drive and everything works fine. I am able to boot to the Hdd and run the OS. I then installed GParted and setup a partition on my RAID as GPT since I want one large partition of 2.78Tib. I then Format it through GParted as ext4 and I am able to mount and access it. I then reboot the system, and can no longer mount the filesystem. What I found interesting is If I reopen GParted I can then mount it. I traced it down to the fact that the until I access GParted the Block Special Device (sil_bgabagabaedd1) does not appear in /dev/mapper. Everytime I reboot I need to go into GParted to restore the Block Special Device then it is mounted. I think I am missing something in the raid setup as to why it is not being retained. What have I missed? What do I need to do to retain the Block Special Device? Is there a boot config setting?

Edit: I did further research and found that if I do kpartx it will appear just as gparted, but on reboot vanishes. I found something similar at this thread but not comfortable in updating dmraid: [URL] I think it is related to gpt and I will try to use a smaller partition to see if the behavior changes.

Ubuntu Multimedia :: Best Codec And Container?

Jun 1, 2010

So I know that Mac OSX post-production and Linux post-production are very different things. I'm hoping to give editing on Linux with Cinelerra a try and I'm wondering, what in FFMpeg's array of codec and container support is widely understood to be the best combination for editing video. I'm looking for the most lossless option so H.264 won't do. Is there a good Apple Intermediate Codec or Apple Pro Res equivalent? Is AVCHD the answer?

Hardware :: CD-ROM Not Mountable In XFCE4?

May 6, 2011

After I upgraded from Lenny to Squeeze, Thunar (in Xfce4) can't seem to detect when a CD is placed in the CD-ROM drive. When I put a USB in the USB port, Thunar adds an icon to the desktop, but with data CDs this isn't happening, and I must mount them from the terminal. However, CDs made from an ISO, for example, my Debian install CD, are detected and appear on the desktop.

Slackware :: USB Devices Not Mountable From Kde?

Dec 17, 2010

i booted up this morning and got a surprise. when i plug in a usb drive normally, it pops up in the k message box, and i can choose too mount it. then it mounts no problem.

when i turned on the computer today, however, i plugged in my usb drive, and clicked to mount it, and lo and behold, i got a strange message:
'Could not mount the following device: USB 8GB'

when i choose more information, i get this:

Code:

org.freedesktop.DBus.Error.AccessDenied: Rejected send message, 1 matched rules; type="method_call", sender=":1.12" (uid=8691 pid=2415 comm="kdeinit4: plasma-desktop [kdeinit]) interface="org.freedesktop.Hal.Device.Volume" member="Mount" error name="(unset)" requested_reply=0 destination="org.freedesktop.Hal" (uid=0 pid=1887 comm="/usr/sbin/hald))

im not entirely sure what this means. i can mount the drive manually through the terminal if it's running as root, but thats not a particularly practical way to do things, as i am a student and often have to switch USB drives and ipods many times a day.

Fedora :: Nikon Camera Is Not Mountable?

Sep 9, 2010

I have a compact-flash card that has some corruptions. I woiuld like to try to fix this by copying out the data from the flashcard using ddrescue or something and then trying to fix the filesystem outside the flash.

BUT Fedora does not allow me to really mount / make a block device of the usb-device, so I can not use ddrescue to copy out the disk-image.

Why is my Nikon camera not a block device, and then the other "GUI-applications" triggered on that device in stead?

Programming :: STL Container Into A C Struct

May 23, 2011

I have an old C application in which i am trying to include some STL cointainers. When i use the STL container alone it works fine, but when i include it into a C struct i have segmentation faults errors. I know that it is not a good idea to mix C and C++. Considering this code:

Code:

typedef struct{
int shmid;
...
APPLSPACETYPE applSpace;

[code]...

and how to make a malloc for this issue; something like :

Code:

mem->applSpace.rData.completeGroups2zeroGroup=(map_completeGroups2zeroGroup_type *)malloc((sizeof(map_completeGroups2zeroGroup_type)+1)* sizeof(char ));

Ubuntu Servers :: WebDAV - Mountable But Empty Below 2nd Subdir Level?

Jul 3, 2011

I am using Safesync from Trendmicro to backup my data. Since some time I am experiencing heavy problems. Normally my Backup should look like this: But when I am mounting it with WebDAV, it is looking different:

Code:
cdrewing@christian-desktop:~$ sudo mount -t davfs http://dav.trendmicro.safesync.com /media/Safesync
[sudo] password for cdrewing:
Gib bitte den Benutzernamen f�r den Server http://dav.trendmicro.safesync.com an; wenn du keinen angeben willst, dr�cke Return.

[Code]...

Note: When I am mounting Safesync with Nautilus, everything is functional and ok. But I need my command line access because I want to use rsync. A workaround could be to access the resource via the nautilus mount. Where can I find this via the command line?

I tried a straight rsync both with the source up and down but mysql won't start on boot after move and if I manually start it none of the websites within the container are able to connect to mysql. I can connect to mysql using telnet of the command line client.

Ubuntu Security :: Truecrypt Container And Clearing Swap?

Sep 27, 2010

my current plan is to create a truecrypt container with the whirlpool hash. This container will be located on a hdd that is not where my OS will be located (so a separate physical sata drive).My concern is when this container is accessed, that some of the password information could be stored in my swap partition (which is on the main drive where the OS "/" is located)

I would like to have a script or command I could run that after I unmount those drives (or just halt the system) that my swap (and ram too if possible) could be wiped (or like overwritten with the shred command). Also, am I going about this the right way, or should I just use truecrypts FDE on the entire drive? In addition, when Ubuntu does it's default install, does it create a swap file in addition to a swap partition? If it does, would that be another vulnerability? If it is, how do I prevent this from happening?

I welcome any input you have on this. I am aware that once the drive is mounted, it is vulnerable, but I want the data to be secure as possible once my computer is turned off. Also, I have read that there are ram exploits where it holds your passwords for up to a few minutes after you turn the machine off, does anyone know how long that it and is there a way to clear it, or will only time let it fade?

Ubuntu Multimedia :: Multiple Dvd Titles In Single Container?

I am able to convert 1 title from the DVD to 1 avi file. One DVD however has 19 titles which vary from 3-5 minutes in length. My question is, can I convert all or at least some titles to a single .avi file and if so how?

General :: Create A Filesystem Mountable By Windows?

Mar 5, 2010

I have attached an external USB disk to my debian gnu/linux system. The disk showed up as device /dev/sdc, and I prepared it like this:created a single partition withfdisk /dev/sdc (and some more commands in the interactive session that follows)formatted the partition withmkfs.msdos /dev/sdc1If I then attach the USB disk to a Windows XP or Vista system, then no new drive becomes available. The disk and its partition show up fine in the disk managment tool under "computer management", but apparently the file system in the partition is not recognized.How do I create a FAT32 file system which can actually be used in windows?edit:I've given up on this and went with a NTFS file system created by windows. In debian lenny this can be mounted read-write but apparently it requires you to install the "ntfs-3g" package and explicitly pass the -t ntfs-3g option to the mount command.
