Ubuntu Installation :: LuksFormat Doesn't Prompt For Passphrase?
Jul 2, 2010
I got a little problem upgrading my ubuntu-nas with some storage.I wanted to add a new harddrive to my lvm but I stuck before getting to this point.I want my harddisc to be encrypted before adding it to the lvm.I tried the following:
Code:
# sudo cryptsetup luksFormat /dev/sdb1 -y
WARNING!
========
This will overwrite data on /dev/sdb1 irrevocably.
Are you sure? (Type uppercase yes): yes
... and nothing happens. dmsetup ls returns nothing.

Every time I log in to my Fedora 13 system, I am prompted for my SSH pass phrase.
I would like to be prompted the first time I login after booting, but then have ssh-agent continue to run until I kill it or shutdown so I don't have to be prompted every time.
Where do I configure this?

I recently was given a system with an ASUS A8V motherboard, AMD Athlon 64 3000+ 1.8GHz CPU and one 60 GB SATA disk to which I added a 120GB IDE disk. As the disks are on different (built-in) controllers and are different speeds, I set up /boot, root and swap on the SATA disk, and then one big /home partition on the IDE drive, using the custom partitioning. If I install Fedora 15 32 bit (from DVD) with encryption enabled, I get prompted for the encryption passphrase during bootup as I would expect. If I install Fedora 15 64 bit (from DVD), I get that same prompt and the boot hangs. I can then bring up a serial console where I'll find a prompt for the same passphrase for the IDE drive. I can enter it and the boot will proceed.
I am now running F15 64 without encryption; I would like to get encryption working again but without having to enter the passphrase twice. Plus I figure that this *should* work the same under both the 64 and 32 bit versions. I have had to reinstall this system a few times, using both versions -- the behavior has been consistent.

I installed ubuntu 9.10 to a fresh partition on a HD that already contains a windows xp. During the install I opted to Require my password to login and to decrypt my home folder, (don't ask why, I regret it already). The install went well, I think, but when it came to reboot time I wanted to check that I could start windows xp from the new grub boot loader. Windows started fine so I rebooted again to try my new install of ubuntu. Now the system seems to get stuck at the little spinning wheel icon. I tried to boot to recovery shell but after entering my name and password I get:
Unable to cd to '/home/myname'
I rebooted using live cd. And mounted the file system as root. Now I have chroot ed into the system but that's as far as my knowledge gets me. I have googled to find the next step but am not finding a clear answer. I have found this [URL]. And here I see I should have seen a screen entitled: Record your encryption passphrase. But I didn't get to that screen. So is there any elegant solution? or am I destined to wipe the install and start again? Perhaps this problem is connected to the bug mentioned here [URL]. Optional encrypted partitions must be marked bootwait in /etc/fstab
In addition to the above, users who have configured any encrypted partitions in /etc/crypttab to start at boot time (i.e., not using the noauto option) should make sure that the filesystems on these volumes are listed in /etc/fstab if they are not mounted at a standard system mountpoint. Failure to do this on a desktop system will lead to problems from the X server and cryptsetup trying to control the console at the same time. At best, this will prevent the user from seeing the passphrase prompt; at worst it will also cause the X server to spin and consume 100% CPU. (430496)
I'm not sure, my /home is not on a separate partition.
/etc/crypttab is empty
# <target name> <source device> <key file> <options>
/etc/fstab is
# /etc/fstab: static file system information.
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
# / was on /dev/sda2 during installation

Ubuntu's request for an encryption passphrase on installation could be greatly improved.
After installation, if the option to encrypt the home folder has been checked, Ubuntu prompts: "Record your encryption passphrase".
On running the action there are the following problems:
# When you type a passphrase, your keypresses are not indicated on the screen
# If you make a mistake typing the passphrase, and backspace, there is no way of knowing whether the backspace operation has worked
# The passphrase is typed once and the operation ends. There is no attempt to validate the correct entry of the passphrase by asking for it to be typed twice.
The combination of these shortfalls can be fatal. My last recorded encryption passphrase proved to be incorrect when after a critical failure I was required to enter my encryption passphrase to retrieve my data. It had not been backed up for a while. Ubuntu did not recognise my passphrase. Only after some dogged support from Canonical was the problem resolved.
I've just done a fresh install. I have butter fingers. I inevitably fumbled over the entry of my encryption passphrase. I have absolutely no way of verifying the passphrase I just set. Should Ubuntu ditch another critical failure on me, what do you think the chances are that my passphrase will work?

I recently started installing Debian and I want to download and install a GUI in it. For that I could use my university Wi-Fi connection. I was told that it's a WPA2 secured connection. But when I tried to configure it, it keeps asking me for a "passphrase". I don't have a passphrase! All I have is my username and password for the Wi-Fi. What should I enter as my passphrase ? I tried both username and password and neither of them worked.

when I click on "Users and Groups" the dialogue box shows up, but I'm unable to make any changes because I'm not prompted for authentication (the "add", "delete" etc., buttons are grayed out). I'm using 10.10.

I just installed debian-6.0.1a-i386-netinst yesterday on my Dell Dimension 4100. I have a serial keyboard and mouse, which both worked fine during the install and the keyboard allowed me to enter the correct passphrase. After I enter the passphrase the PC continues to boot up, and it gets to a black screen with small fuzzy/distorted "DELL" logo's on the top part of the screen going from left to right.
What is wrong with my PC? What can I do to troubleshoot this?
I really would like to get debian up and running on this desktop

I have a PDF that I built using BIRT, and that works fine. At this point I'm trying to print it using lpr or some other command. It seems as though I should just be able to type lpr invoice.pdf and it should print to the default printer. However, lpstat -t shows "Empty print file!" for the printer, and the printer doesn't do anything, let alone print the file. lpr -l invoice.pdf prints the file, but unformatted - just a bunch of characters and whitespace on a seemingly infinite number of pages.

I am trying to install Fedora alongside Ubuntu but have run into a bit of a snag. I have the ISO burned to a disc, but it will not load on startup and doesn't have a prompt when the cd loads normally. I have files on the cd, but Ubuntu cannot read them.

I have Update Manager set to check for updates on a daily basis but to prompt me before downloading or installing them. Because I have Update Manager set to check on a Daily basis, I expect that I will receive a prompt that an update is available no later than the day after the update is available (assuming of course I have my computer turned on). Yet I only receive a prompt days or even a week after the update was made available.
For example, let's say that my PPA of Google Chrome issues an update on Tuesday. Despite the fact that my ubuntu computer was on for a couple hours in the morning on Wednesday, Thursday, and Friday, no update prompt appears alerting me to available updates. If I manually open Update Manager on Friday afternoon, then the update is there and waiting for installation. But how come I don't get an automatic prompt that an update is available? Do I have my settings wrong or something?

I have used CentOS for a while and have never run into this issue. I searched all over and didn't see a similar issue anywhere, I did an install of CentOS as a server (no GUI) with only the base. Partition is /boot ext3, size of 100MB. The rest of the drive is partitioned as / with ext3. This is being done on a CompactFlash card of 32GB in size. The BIOS sees it as an IDE drive.
When the install completes and the system reboots, the grub stops at the grub> prompt. There is no menu for OS options. If I do the following commands:
grub>root (hd0,0)
grub>kernel /vmlinuz-2.6.18-194.el5 root=LABEL=/
grub>initrd /initrd-2.6.18-194.el5.img
grub>boot

I'm running Red Hat Linux 5.4 on HP DL580 server with 16 processors and 64 GB of RAM. I'm connecting to the server remotely through SSH. after entering the password, it takes time to return the command line, if I click ctrl+c during this time, I'll have the command line prompt but not the correct bash prompt (I have to run bash to pass to my correct prompt).I tried to install Apache on the server, ./configure took 4 hours to finish instead of 1 or two minutes, Oracle installation same behavior. Server Disks are mirrored using RAID controller.

I installed 10.04 clean on the PC.Not other operating system.It booted to Ubuntu fine after the install and all appeared to be working fine.Used the upgrade manager to install the upgrades to the basic system.I had not yet loaded in any non-ubuntu or medibuntu repositories so this was the first, basic upgrade.After the upgrade,I can no longer boot to Ubuntu but boot to a grub prompt instead.I presume this is a recover prompt. How do I "recover" and continue booting to Ubuntu?

I decided to upgrade my FC installation to the latest version - FC itself offered the upgrade when I turned the machine on, so it appeared that it was nicely packaged to make the upgrade easy.After a long download of packages, the machine rebooted and then started taking me through configuration options (timezone, disks to use for the installation etc) but then it crashed trying to write to disk and now leaves me at a grub prompt whenever I boot.Is there any way to "get at" the installation files and get back into trying to install or do I now need to download an ISO and burn a DVD and start all over again?

what purpose does it serve to use a passphrase? Once the keys are generated the passphrase isnt used? Or what am I missing??? I did not use a passphrase and understood that there was no security implications of not doing so. Is this correct?

After I completed the install I get GRUB prompt and I cannot type anything.

I am a noob who is playing around with setting up a home print/file server using Ubuntu Server 10.04. I have successfully setup the server and am now configuring the SSH server so I can control remotely.
I have setup RSA keys with a passphrase as outlined in the SSH - Ubuntu Community Documentation. However, when I log in remotely I am only asked for the passphrase the first time. Any subsequent log-ins simply take a few seconds to connect without any passphrase request. After restarting my laptop (that I use to connect remotely), I am again asked for the passphrase only the first time and subsuquent logins are without a passphrase. I would like to know if this is normal and if there is a way to have passphrase requested on each login.

I'm quite a newbie, and that being terse haven't ever been in the list of my virtues. Still, I tried so many things, that this post couldn't possibly be shorter then it is.Yesterday I upgraded my Kubuntu from 9.04 to 9.10 using adept. During upgrade I accepted everything that was offered including (one)new configuration file for I don't know what. After reboot I still had grub1, after trying regular boot system froze with error message that usplash process doesn't exist or so; briefly, only recovery mode worked properly. I think I entered clean option accidentally, if not, I haven't done anything special, yet after n-th reboot usplash problem disappeared, but I had another freezing screen, with something like:
Quote:
mount: proc already mounted on /proc
mount: UUID=d6163745-e30e-4c00-b158-66e46d40b1a8 already mounted on /home
mount: /dev/scd0 already mounted on /media/cdrom0[code]....
plus it said it cannot mount everything from fstab. Problem was partition from another computer that was smbfs, which is truly not reachable right now. Someone said it's problem with mountall.I tried solutions I found here:
1. provided by @kentaur
mount -o remount,rw /
sudo dpkg --configure -a[code].....
PS. Isn't ubuntu suppose to resolve dependencies automatically?

I installed 64 bit Lucid Lynx last week. There were some issues with the grub boot manager and my windows boot manager. However, about half the time i would boot to reach only a login prompt. If i used CTRL ALT DEL i would then reboot usually into the GUI.So now i only reach a login prompt all the time. How do i get the the GUI to run automatically?
