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?

I have encountered a bug in the live-build in Debian Live. The persistence does not work it is because of the bug #767195. I cannot recreate another live img file because of bandwidth problem, is there any way to repack the initrd and enable the cryptsetup?
as per suggested:
#767195 – cryptsetup needs to be enabled for initramfs inclusion – Debian Bug report logs

I have a simple usb mount problem, but after looking around, haven't been able to solve it. So far I've come across hal, dev, usbmount,pmount, and got lost in all this.
So, when I plug my usb as non-root I get that "not authorized" message. I solved this by installing usbmount package. After that, as non-root, usb mounts, but I can't write, I only have read rights. I tried changing "MOUNT OPTIONS" in usbmount.conf, but no luck.
What is the proper way of automounting usb and how to control access rights and what user can do what?
I also tried with fstab entries, but everytime I unplug my usb stick and plug it back in, /dev entry changes...

Could anyone tell me how to get Debian Lenny to automount CDs the same as Ubuntu does i.e. automatically, with a Desktop icon etc.I've worked out how to automount CDs using autofs, which is OK, but it still doesn't seem quite as good as the way Ubuntu does it.

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.

Is there a way to set up your system (running CLI only, no X) to automount flash drives? I know how to mount them manually, but I'd really like it if there was a way to just have the system do it automatically when I plug the drive in so I don't have to do it myself every time.

I would ask how automounting of devices works in debian. I'm trying to modify the name of automatic mount point from the label name of devices (or their UUID) to the devices name. That because the UUID is often a very complicated string, meanwhile the label often contains spaces; so become difficult working with theme in scripts...

The simple question 'How do I list all the used/unused LUKS slots' wasn't found in either cryptsetup Wiki or its man page.Is this possible - to list all the available/used LUKS slots for a given device?

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

I have a small issue where an USB harddisk is not automounting. CD's, USB pens etc. are automounting without issues, so it is a little bit strange.I am mounting it with UUID, because I want the mount point to be the same everytime.As you can see from the fstab, it is NTFS.
dmesg
[92.388083] usb 1-1: new high speed USB device using ehci_hcd and address 4
[93.079778] usb 1-1: New USB device found, idVendor=0bc2, idProduct=0502

I have recently bought a Toshiba 1TB external USB disk.
I have formatted it using gparted to ext2 and Debian see's it but gives me an error "unable to mount volume" with some extra stuff about programs shouldn't disconnect shared drives.
I can mount it ok by creating a folder called usbdisk and the mount command "mount -t ext2 /dev/sda1 /home/mike/usbdisk" and it works fine, but I have to do this everytime I start the machine.
Does anyone know what exactly I should put into a setup file to make the machine do this everytime , but only if its there.
As I'm not very clued up on bash scripting , I'm assuming it something along these lines:
How would I add this at boot?? Would I add it to the end of "init.d/rc" ?

I don't have an opportunity to check it out now... Does Debian 6 testing mount inserted CDs/Flash-drives automatically like Ubuntu does? Or the only way to mount them after inserting is to use mount command?

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

I'm using Debian Squeeze XFCE along with Windows 7 as dual boot on my notebook. I want to access my Windows 7 partitions from Debian for both reading and writing. I was a Ubuntu user in which the Windows partitions were visible by default. I want to know how to mount the drives used by Windows 7 automatically on startup.

I'm trying to familiarize myself with LXDE to help a friend of mine and one thing I just cannot solve, despite many googles, is how to allow a non-root user to auto-mount drives in the left-hand pane of PCMANFM.Everything works just fine as long as I have the root passwd. Not a huge problem but very irritating none-the-less.

I have a problem copying my udev rules from other distro to another pc running debian. My box is running debian without any DE and I want my USB disks to be automounted based on the label; I believe udev is the nicest way to do this task.
Anyways : my rules are (copied from archlinux wiki btw)
cat /etc/udev/rules.d/92-my-media-automount.rules
# vim:enc=utf-8:nu:ai:si:et:ts=4:sw=4:ft=udevrules:
# /etc/udev/rules.d/92-my-media-automount.rules
# Only work on sd*
KERNEL!="sd[a-z]*", GOTO="my_media_automount_end"
ACTION=="add", PROGRAM!="/sbin/blkid %N", GOTO="my_media_automount_end" .....
I notice the directory is made successfully up inserting the usb HD, but the mount doesn't succeed. If I manually execute above command, the mount goes ok.

I'm running Debian sid and currently have xfce 4.8.0 installed. I have the thunar-volman package and it is configured to automount everything (cdrom & usb). I have hal, udev, gamin and autofs installed as well.For some reason though, automount just isn't working. It's starting to annoy me.I can mount the devices manually.I looked around already but most posts just advise you to install hal or something.

I'm running Debian 8.1 Jessie on a Dell Latitude D400 using the GNOME Flashback DE. I cannot for the life of me figure out why it doesn't automout my USB drives and CD/DVDs.The regular GNOME and GNOME Classic will automount no problem but Flashback will not. It shows up in Nautilus but I have to mount it manually through Nautilus. I checked in dconf Editor under org/gnome/desktop/media-handling and automount IS checked. So I can't figure out why its not automounting.
Is there a way to fix that so Flashback will automount my CD/DVDs and USB drives or is it just a bug in Flashback that I gotta wait to get fixed?I've already searched the forum and Google to no avail but its possible I didn't use the right searh terms in Google.

I have a 2 Computers:
Computer A has a RAID array in it, and everything works perfectly fine. When Computer A powers on, the RAID array is automatically mounted, mdadm takes care of all of the things it's supposed to, and an icon for the RAID array is automatically placed on the desktop. Everything Just Works (TM).
Computer B is configured similarly to Computer A. They have identical configuration files (at least, all the ones I've checked are identical), and when Computer B powers on, the RAID array is automatically mounted, mdadm takes care of all of the things it's supposed to, BUT, NO icon for the RAID array is automatically placed on the desktop. How do I change that?
They have identical /etc/fstab's (the lines in bold are the ones that matter):
Computer A
mediaserver:/home/mediaserver/Desktop# cat /etc/fstab .....
Computer B
mediaserver:/home/mediaserver# cat /etc/fstab
# /etc/fstab: static file system information .....
They have identical /etc/mdadm/mdadm.conf's
Computer A
mediaserver:/home/mediaserver/Desktop# cat /etc/mdadm/mdadm.conf
DEVICE partitions
CREATE owner=root group=disk mode=0660 auto=yes
HOMEHOST <system>
MAILADDR root
ARRAY /dev/md0 level=raid5 num-devices=4 metadata=0.90 UUID=82bfcecf:5cd4d557:2f1fbd23:68e2797c
Computer B
mediaserver:/home/mediaserver# cat /etc/mdadm/mdadm.conf
DEVICE partitions
CREATE owner=root group=disk mode=0660 auto=yes
HOMEHOST <system>
MAILADDR root
ARRAY /dev/md0 level=raid5 num-devices=4 metadata=0.90 UUID=6c24c0e5:84ead07e:c109596b:d7e29b7e
The outputs of mount are also very similar:
Computer A
mediaserver:/home/mediaserver/Desktop# mount
/dev/hda1 on / type ext3 (rw,errors=remount-ro)
tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)
proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
procbususb on /proc/bus/usb type usbfs (rw)
udev on /dev type tmpfs (rw,mode=0755)
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=620)
/dev/md0 on /mnt/arrayCOMP_A type xfs (rw)
Computer B
mediaserver@mediaserver:~$ mount
/dev/hdc1 on / type ext3 (rw,errors=remount-ro)
tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)
proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
procbususb on /proc/bus/usb type usbfs (rw)
udev on /dev type tmpfs (rw,mode=0755)
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=620)
/dev/md0 on /mnt/arrayCOMP_B type xfs (rw)
mediaserver@mediaserver:~$
So how do I get an icon for the device /dev/md0 to automagically appear on the desktop every time the device is mounted (which occurs every time the computer boots up)?

I have a usb drive formatted using mkdosfs, and it must be manually mounted every time because it says "wrong fs type, bad option. bad superblock on /dev/sdb1, missing codepage or helper program, or other error" but it mounts just fine when I manually mount it. It would be nice if gnome would mount it when I plug it in instead of me having to go into root and mount the drive.

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

If you want, skip straight to the 'QUESTION' at the end of my post & refer to the 'EXPLANATION' later. EXPLANATION: Using Debian 6.01 Squeeze 64-bit. Just put together a brand new 3.3Ghz 6-core AMD. I had a nightmare with my Highpoint 640 raid controller, apparently because Debian Squeeze now handles raid through sysfs rather than /proc/scsi. The solution to this, of course, is to recompile the kernel with the appropriate module for /proc/scsi support. So I thought "screw that" and I've yanked out the raid card & went with Debians software raid. This allowed me to basically complete my mission. The raid is totally up and running, except for one final step... I can't get the raid to automount at boot.
My hardware setup;
- Debian is running totally on a 64Gb SSD. (sda)
- I have 3x 2Tb hard drives used for storage on a raid 1 array (sdc,sdd,sde)

I'm using squeeze. hal allows any user (at least, ones logged into the console) the ability to automount any removable drive that is plugged in. I want to restrict the ability to automount to users who are in the group that owns the device node for the drive (some distributions use the "plugdev" group for this.) I know I can turn off automount individually in each desktop, but seeing as hal is the thing that runs as root and is actually doing the mounting, it seems to make the most sense to change the setting in hal.
