  • JUJU and ERROR environment has no access-key or secret-key

    - by Riccardo Magrini
    following the official guide: [1]https://juju.ubuntu.com/docs/config-maas.html and considered that I've generated the ssh key (added it to UI of MAAS) and the API key, my environments.yaml file presents in this way: environments: maas: type: maas maas-server: 'http://x.x.x.x/MAAS/' maas-oauth: 'NDPA86PsEzS7bFynSy:vqJLkyHUJbvYzbtY5Q:sXXXXXXXXXXXXXXXXXXXXXX admin-secret: 'nothing' default-series: precise authorized-keys-path: ~/.ssh/id_rsa.pub # or any file you want. when I try to run the command: juju bootstrap receive the following error: ERROR environment has no access-key or secret-key Someone can explain me where is the wrong? MAAS and JUJU are installed using their ppa stable on an Ubuntu 12.04.3 Server

  • Cannot login in account with encrypted home after update from 11.04 to 11.10

    - by martin
    After upgrading from ubuntu 11.04 to 10.10 I cannot access my encrypted home partition anymore. I can login, however all data stays encrypted. ecryptfs-mount-private gives: ERROR: Encrypted private directory is not setup properly Any idea how to fix this?

  • Share home directory between Linux and Windows dual boot

    - by user877329
    This question is somewhat similar to How to use Windows Share has home directory, but in this case Windows is not running. I have installed a dual-boot configuration with Ubuntu 12.04 and Windows. My Windows partition is mounted on /C. Now I want either Ubuntu to locate home directories in /C/Users Which is the location of windows accounts or I want Windows to use D:\home for home directories. (D is the name of the Ubuntu root directory). For the first approach, I have managed to create a test user account test-user:x:1004:1001:Test:/C/Users/test-user:/bin/bash The account works but test-user cannot run any X session. From .xsession-errors chmod: Changing rights on ”/C/Users/test-user/.xsession-errors”: Operation not permitted Would it help get rid of that chmod, which has no effect? How do I? If I use the second approach, I need the Ext2fsd driver, which seems to work, but I am not sure if Windows maps the Ext2 system that early. Here is my fstab proc /proc proc nodev,noexec,nosuid 0 0 UUID=e7cef061-ed8d-4a82-b708-0c8f4c6f297f / ext3 errors=remount-ro 0 1 UUID=2CDCEB43DCEB0644 /C ntfs defaults,umask=007,gid=46 0 0 UUID=b087b5c0-b4bd-47e7-8d34-48ad9b192328 none swap sw 0 0 Update: I found something here: http://www.tuxera.com/community/ntfs-3g-advanced/ Will work if i do a correct mapping between NT users and Linux users.

  • My home partition slowly fills up until the system is unable to complete even simple tasks

    - by user973810
    So I have an awesome configuration on my home pc. My /home directory has its own partition. My home partition slowly fills up until the system is unable to complete even simple tasks. For example, when this issue has occured, I can load up firefox. It just pops up an error message saying that it cannot be done. Rebooting solves the issue. The strange thing is, I've run baobab and it doesn't notice a problem. There should be hundreds of gigabytes of data somewhere, but it doesn't see it. Does anyone have any idea of how I might troubleshoot this issue? I'm thinking I could do lsof but I've always found the output of that to be too much information. Maybe my drive is, like, dying. Edit: is there a /home analog of /var that gets cleared out at boot time? Maybe I could check in there next time I notice this problem to see if I can divine what's up. Update: I found the issue. my .xsession-errors file is filling up with Authentication deferred - ignoring client message Is there a way I can see what is causing this error and fix it?

  • Encrypted Home directory not auto mounting

    I somehow managed to break auto-mounting for my encrypted home directory.

  • Move the home directory back to single partition

    - by Nathan J. Brauer
    I've seen a ton of tutorials on how to move your home directory to a separate partition. I want to do the opposite. I have two HDDs. One /home/ and the other is everything else (both drives have only one partition). I'm selling the computer but want to keep one of the hard drives. So, I'd like to move the home directory and system files back onto a single drive. Which ever way is quickest/easiest (separate partitions or all on one partition). Thank you!

  • Installing Ubuntu 12.10 with encrypted root and encrypted /home on separate partition

    - by peterrus
    Is it possible to have Ubuntu 12.10 with an encrypted root partition and an encrypted home partition (using preferably the same encryption mechanism)? This question is somewhat the same: How do I install Ubuntu with encrypted root, home, and swap partitions? But is not answered. As I am using a dualboot setup I can not use the automatic partitioner (which doesn't support your /home on a separate disk/partition anyway). So I would have to configure some things manually. How would I do this?

  • Is it possible to boot without mounting /home?

    - by Exeleration-G
    I want to backup my /home partition on /dev/sda6 using partclone, a command line utility. To do so, I first have to unmount the partition that I want to backup. Most of the time, this is easy, but /home is used by so many processes that it can't be unmounted without first killing all those processes. So, the thing I'm looking for is a way to boot Ubuntu, without mounting /home, so I can back up the not-mounted /dev/sda6 partition. Is that possible? To be clear, it would be nice if this special boot could be 'one-time-only'. So I'm not looking for ways to change /etc/fstab in such way that /dev/sda6 won't be mounted. That's because that would require me to change /etc/fstab twice each time just to make a backup. I'm aware of the fact that there are other backup solutions available, such as deja-dup. I'd like to use partclone, though.

  • Encryption Product Keys : Public and Private key encryption

    - by Aran Mulholland
    I need to generate and validate product keys and have been thinking about using a public/private key system. I generate our product keys based on a client name (which could be a variable length string) a 6 digit serial number. It would be good if the product key would be of a manageable length (16 characters or so) I need to encrypt them at the base and then distrubute the decryption/validation system. As our system is written in managed code (.NET) we dont want to distribute the encryption system, only the decryption. I need a public private key seems a good way to do this, encrypt with the one key that i keep and distribute the other key needed for decrpytion/verification. What is an appropriate mechanism to do this with the above requirements?

  • Foreign key reference to a two-column primary key

    - by Adam Ernst
    One of my tables has a two-column primary key: CREATE TABLE tournament ( state CHAR(2) NOT NULL, year INT NOT NULL, etc..., PRIMARY KEY(state, year) ); I want a reference to the tournament table from another table, but I want this reference to be nullable. Here's how I might do it, imagining that a winner doesn't necessarily have a tournament: CREATE TABLE winner ( name VARCHAR NOT NULL, state CHAR(2) NULL, year INT NULL ); If state is null but year is not, or vice-versa, the table would be inconsistent. I believe the following FOREIGN KEY constraint fixes it: ALTER TABLE winner ADD CONSTRAINT FOREIGN KEY fk (name, state) REFERENCES tournament (name, state); Is this the proper way of enforcing consistency? Is this schema properly normalized?

  • Primary Key Identity Value Increments On Unique Key Constraint Violation

    - by Jed
    I have a SqlServer 2008 table which has a Primary Key (IsIdentity=Yes) and three other fields that make up a Unique Key constraint. In addition I have a store procedure that inserts a record into the table and I call the sproc via C# using a SqlConnection object. The C# sproc call works fine, however I have noticed interesting results when the C# sproc call violates the Unique Key constraint.... When the sproc call violates the Unique Key constraint, a SqlException is thrown - which is no surprise and cool. However, I notice that the next record that is successfully added to the table has a PK value that is not exactly one more than the previous record - For example: Say the table has five records where the PK values are 1,2,3,4, and 5. The sproc attempts to insert a sixth record, but the Unique Key constraint is violated and, so, the sixth record is not inserted. Then the sproc attempts to insert another record and this time it is successful. - This new record is given a PK value of 7 instead of 6. Is this normal behavior? If so, can you give me a reason why this is so? (If a record fails to insert, why is the PK index incremented?) If this is not normal behavior, can you give me any hints as to why I am seeing these symptoms?

  • Motion is saving images to home directory

    - by Kevin
    I was interested in setting up a home security network. I installed Motion in Ubuntu 12.04 and it worked fine. Then the next day I went to play around with it some more but the images are not being saved to /tmp/motion as the configuration file states, but to the home directory: [1] File of type 1 saved to: ./01-20121126211634-12.jpg Any idea if there is another setting that has more priority than the motion config file?

  • Clean install with home folder and multiple users

    - by haydoni
    I had reformatted my system (unfortunately an update failed) and had my home folder on a separate partition. Thankfully I still have all of my users files (in their respective folders), but there was no option to use this on install (since my update had failed...). How can I recreate the old users with their previous home directories? (Are there problems with user permissions with just dragging and dropping the entire contents of folders?)

  • Pressing "Home" in Vim on an Indented Line

    - by Reid
    I have a bad habit of using the 'home' key to go back to the beginning of a line. As I recently started using vim (and loving it!) I noticed that when I press the home key on a lined that is indented, it returns me to the very beginning of the line. In Notepad++ (the editor I used to use) it would return me to the beginning of the code on that line, right after the indent. Is there some way to replicate this behavior in vim? Usually, when I'm pressing home it's in the Insert mode for me to (usually) stick a variable there. I have set smartindent in my vimrc, with set noautoindent as a "tips" page told me to make sure to disable autoindent (although it didn't seem to be enabled in the first place - perhaps that option is extraneous.) Thanks in advance.

  • SSH Public Key - No supported authentication methods available (server sent public key)

    - by F21
    I have a 12.10 server setup in a virtual machine with its network set to bridged (essentially will be seen as a computer connected to my switch). I installed opensshd via apt-get and was able to connect to the server using putty with my username and password. I then set about trying to get it to use public/private key authentication. I did the following: Generated the keys using PuttyGen. Moved the public key to /etc/ssh/myusername/authorized_keys (I am using encrypted home directories). Set up sshd_config like so: PubkeyAuthentication yes AuthorizedKeysFile /etc/ssh/%u/authorized_keys StrictModes no PasswordAuthentication no UsePAM yes When I connect using putty or WinSCP, I get an error saying No supported authentication methods available (server sent public key). If I run sshd in debug mode, I see: PAM: initializing for "username" PAM: setting PAM_RHOST to "192.168.1.7" PAM: setting PAM_TTY to "ssh" userauth-request for user username service ssh-connection method publickey [preauth] attempt 1 failures 0 [preauth] test whether pkalg/pkblob are acceptable [preauth[ Checking blacklist file /usr/share/ssh/blacklist.RSA-1023 Checking blacklist file /etc/ssh/blacklist.RSA-1023 temporarily_use_uid: 1000/1000 (e=0/0) trying public key file /etc/ssh/username/authorized_keys fd4 clearing O_NONBLOCK restore_uid: 0/0 Failed publickey for username from 192.168.1.7 port 14343 ssh2 Received disconnect from 192.168.1.7: 14: No supported authentication methods available [preauth] do_cleanup [preauth] monitor_read_log: child log fd closed do_cleanup PAM: cleanup Why is this happening and how can I fix this?

  • Error on /home prevents OS boot

    - by mdrg
    Ok, I'll try to explain it listing the events: motherboard battery is weak, loses config everytime I shut the PC down; system clock usually back to 1990-something; this time, it went up to 2148; ubuntu became somewhat unusable (firefox refusing certificates, dropbox blocked), so I restarted; manually set the clock to current date and restarted; during boot, ubuntu detects errors and start auto-fix, rebooting itself in the middle of it (like a hard reboot, no shutdown messages) next time, shows boot animation screen in text mode, with an error message after a while: "Errors were found while checking the disk drive or /home", with "attempt to fix, ignore, skip mounting or manual recovery" None of the options during the boot work, they just type the text to the screen, then I'm forced to physically restart. Now I'm using Mint LXDE live CD, and I can see all my partitions just fine, including /home (my home folder blocked due to encryption, the other user folder is accessible and everything in place). I'm not sure how to proceed now. I'd like to just fix ubuntu boot without reinstalling or anything like it (at least until 12.04). What should I do now? can I easily fix this somewhow? Thanks!

  • Standard way to hash an RSA key?

    - by Adam J.R. Erickson
    What's the algorithm for creating hash (sha-1 or MD5) of an RSA public key? Is there a standard way to do this? Hash just the modulus, string addition of both and then take a hash? Is SHA-1 or MD5 usually used? I want to use it to ensure that I got the right key (have the sender send a hash, and I calculate it myself), and log said hash so I always know which exact key I used when I encrypt the payload.

  • Deleted some files from home folder

    - by narendra shah
    I have recently installed Ubuntu for the first time in my life. So I am fairly new to it. I have deleted some files from my home folder. But now the problems have started. The system volume automatically reduces to zero. Further, as soon as I restarted my system, my panel settings we restored to default. When I right click in my home folder, it gives an option of 'restore missing files' but I am not able to restore them. Please guide me how to restore them. Thanks Narendra

  • Sharing my home folders with other users on the same PC

    - by Stephen Myall
    After reviewing similar questions on the same subject Im still none the wiser. I want to share my music, pictures and video folders with other users on my pc. I am using 11.10 and will be upgrading to 12.04. The method I have tried is to right click on the folder (as Administrator), select "Sharing Options" check all the necessary fields and give the share a name like "music-shared". Another dialog pops up then and I select "Set nautilus Permissions". When the other user logs on they go to their Home folder click on the network and can see the "music-shared" folder, but they get a message that the do not have the necessary permissions to view the content. Im sure I'm missing something simple. My Home folder is encrypted and i am willing to unencrypt to make this work Unlike other questions on this site, I dont have a partition etc. i would be grateful for any help.

  • '/'var/www/' vs '/home/$USER/public_html'

    - by OrganizedFellow
    I recently started using Ubuntu as a LAMP server. I've come across plenty of tutorials that say to place the files at '/var/www/' and I've also seen others that put them in '/home/$USER/public_html/'. During my testing and figuring stuff out, I was successfully able to view a test site URL from each location. Is one better than the other? I thought that maybe it was just preference. But the more I think about it, the more I want to keep all my work in my Home folder.

  • Using datetime float representation as primary key

    - by devanalyst
    From my experience I have learn that using an surrogate INT data type column as primary key esp. an IDENTITY key column offers better performance than using GUID or char/varchar data type column as primary key. I try to use IDENTITY key as primary key wherever possible. But recently I came across a schema where the tables were horizontally partitioned and were managed via a Partitioned view. So the tables could not have an IDENTITY column since that would make the Partitioned View non updatable. One work around for this was to create a dummy 'keygenerator' table with an identity column to generate IDs for primary key. But this would mean having a 'keygenerator' table for each of the Partitioned View. My next thought was to use float as a primary key. The reason is the following key algorithm that I devised DECLARE @KEY FLOAT SET @KEY = CONVERT(FLOAT,GETDATE())/100000.0 SET @KEY = @EMP_ID + @KEY Heres how it works. CONVERT(FLOAT,GETDATE()) gives float representation of current datetime since internally all datetime are represented by SQL as a float value. CONVERT(FLOAT,GETDATE())/100000.0 converts the float representation into complete decimal value i.e. all digits are pushed to right side of ".". @KEY = @EMP_ID + @KEY adds the Employee ID which is an integer to this decimal value. The logic is that the Employee ID is guaranteed to be unique across sessions since an employee cannot connect to an application more than once at the same time. And for the same employee each time a key will be generated the current datetime will be unique. In all an unique key across all employee sessions and across time. So for Emp Ids 11 and 12, I have key values like 12.40046693321566357, 11.40046693542361111 But my concern whether float data type as primary key offer benefits compared to choosing GUID or char/varchar as primary keys. Also important thing is because of partitioning the float column is going to be part of a composite key.

    Mine is a 64 bit machine and I had installed "32" bit Ubuntu to try it out and hence installed many apps and developed many things and configured it for many things. Now it seems that my laptop needs more resources as my development needs so much. My question is :to free up install Lubuntu "64" bit in other partition which uses the same home directory and apps and my development rendering my laptop to be faster than before. Is this possible ? Thanks in Advance.
