Let's suppose that a machine has three users:
(1) david
(2) dan
(3) joel
The computer now restarts and during the log-in process, I choose to login into dan's account.
At this point, when I am logged in into dan's account, will Ubuntu run the crontab jobs that belong to david / joel?
As per subject, what's the best way to run a CRON job for something that "normal" users need to run as SUDO? There is a problem with the internal clock on my PC so at a regular time (every hour or day for example) I want to sync with my Network Time server. I use "sudo ntpdate time.bgr.local" as it is now and have to enter my user's password for it to work.I know root is disabled by default and would like to keep it that way if possible but if I have to enable it and then add it to root's cron list the so be it but would prefer not to.
View 5 Replies View RelatedI have a file server that is an NIS client. User home directories are auto-mounted from another server. Users are not able to run cron jobs. The /var/log/cron logs says:
Jan 6 14:33:01 inclination crond[3217]: (username) ORPHAN (no passwd entry)
I tried adding an entry in /etc/passwd, /etc/group, and /etc/shadow but the test script I have still doesn't seem to run although cron thinks it did. The log entry for these attempts looks like:
Jan 6 15:30:01 inclination crond[4312]: (username) CMD (/home/username/test-script)
Now root does seem to be able to run cron jobs with no problem. My test script works fine from cron when runs as root. I suspect there's an issue with how I have NIS configured but I can't find any info. The test script runs fine from the command line when logged in as myself.

I had Ubuntu 9.10 running ok, but I've decided to try Lucid Lynx with Kubuntu and was quite impressed with the quality of KDE.

One regarding the network manager (which I think it was given just because it was already started by another user), and the ibus error, which completely locks the user from accessing any other drive or usb disk.For the third user, even if creating it from scratch (not re-using his /home), I get an error:

Ok, for various (mostly security) reasons I was experimenting in running certain apps as a different user id (on Karmic).
I can get X to forward to my main session without a problem but I cannot get the sound to work. Sound works fine in my main session, but when I run sound as another user I get plenty of errors like:
PHP Code:
ALSA lib pcm_dmix.c:1008:(snd_pcm_dmix_open) unable to open slave
I am not a big linux GUI person, so I have rarely dealt with sound systems under Linux. What is the simplest way to get this to work in a relatively secure way? (I do realize that my security is already a bit compromised by allowing the secondary user access to X, but that can't be helped)
I want to add users from the command line, I know I can use the adduser for individual users, but if you have 50 or more there must be another way. I'd rather not use the GUI.

Day-to-day admin : me in France with an Azerty keyboard
Level 1 24/7 support : team in US with a Qwerty keyboard
Of course there's commands like sudo dpkg-reconfigure console-setup but this one affects the whole system. I've searched quite a lot on how to change the keyboard layout for one person only, but it always relates to the Gnome interface. So I'd like to know if you knew a way to locally change the keyboard layout, only the SSH connection of the user? Maybe in the startup scripts of the bash session, or even better, when the user types his user login (so it detects his language and automatically switches to the right keyboard).

View 1 Replies View RelatedI have a small ubuntu server setup and I would like to create a directory that can be written to by a select number of users. I have a backup directory setup and I want to enable my account as well as three others to be able to read/write to that directory. So far I haven't had any luck.
The owner of the backups folder, a directory on a separate disk mounted under /srv/storage, was owned by root and under the root group. I added the group backups and then changed the backups directory group to backups. I then used chown to change the backups directory to 775 to enable group members to write to it. I then tried to touch a file in the backups folder but no such luck. I did notice that when I run groups, my user account isn't shown as belonging to backups but is shown under the /etc/group file. I even made sure the GID of backups is in fact below 1000.
Anyone have an idea on how to create a shared directory that everyone can create, modify and delete any file? I believe my problem is related to the fact that root is the owner of the backups directory.
I just created a 2nd user on my computer. I've got the hard drive that ubuntu runs on, and then a 2tb drive for media. If the 2tb is mounted on my desktop, it won't show up on his desktop even if I'm logged out. It won't show up on his unless I unmount on mine.
If I'm logged out I'm obviously not using it. So why doesn't it show up? He has all privileges. Is there a way to make this work without having to unmount?
I'm running karmic btw. If you need computer info let me know what to type into the terminal and whatnot and I'll paste it all here!
I have a small problem regarding multiple X sessions. I want 2 X sessions started automatically on boot with 2 different users auto logged in and 2 different sessions running.
On first X session I would like to have gnome running with user1
On second X session I would like to have xbmc running with user2
So far my computer logs user1 in to a gnome session via gdm on boot. But then I have to launch a tty, log in as user2 and then start xbmc in a new X session.
How to make it work? I would also love to have the second X session active after boot. I am running Ubuntu 10.04.
On Ubuntu 10.04 when there are more than just one user logged in, if one of users logs off system hangs with a black screen.
After I reboot the machine and log in again, just after GDM login screen I get a window with a message about PowerMeter crash, with suggestion to 'cancel' and 'log off'. Only 'Log off' works, i.e. I'm successfully logged in.
Last entries from system.log before system freeze are:
Code:
Ubuntu 10.10 Server is loaded. Openssh has been loaded.
I have multiple users which need access to server via ssh.
My impression from reading about ssh is that a key needs generated for each person. Thus, each key will have a passphrase that is unique to them.
In /etc/ssh/sshd_config, the default sshd_config suggest using:
%h/.ssh/authorized_keys
My assumption is %h is a variable that will allow the current user to use the public key stored in his home directory under the .ssh folder in a file called authorized_keys. Is their a command string that automatically populates the authorized_keys file?
I am surprised that even though there are a number of hidden (e.g. .****) files located in the home folder, there is not one automatically generated as .ssh. It appears I have to create that directory myself. I am especially surprised by this since it appears the instructions for generating a key seems to load the key in the home directory instead of proceeding to create a .ssh folder to store the keys in.
It is not clear, but it appears that the public key needs to be copied or appended to the authorized_keys file, but, using the scheme above, the public key needs to be copied or appended to each users authorized_keys file instead of appending all public keys to a single authorized_keys location.
It then appears that each persons authorized_keys file needs permissions set to 600.
It also appears that if I decide to use RSA instead of DSA, I would do the same thing above but would use authorized_keys2 file instead.
Why doesn't the home folder which gets automatically set up for each user automatically get a .ssh folder generated? i.e Why does it have to be created by hand? Does it need the same permission on the .ssh folder? ie 600?
My aim is to allow many to log on via ssh simultaneously and then allow many to simultaneously vnc into their respective gnome desktops.
Idealy I want to create a batch file which would read the list and create a user and a password.
I know i need to create the file using the vi command and using the useradd facility to add the users however where i go from there i am lost.

I'm using a Ubuntu Desktop 10.04 32-bit machine as my file server. It is sharing a few folders stored on a USB NTFS drive using Netatalk. The client machine is running MacOS 10.6.4. I have only one user on the Ubuntu machine, but the Mac machine has two users. I wish to share the same network share between the two Mac users, while both are logged in (they switch between one another without logging the other one out).
I created a login item on both Mac user accounts to automount the Ubuntu shared folder and used the same Ubuntu user account for authentication on both Mac accounts. This is the problem: When the first Mac user logs in, the shared folder automatically mounts with no problems. However, when the second user switches to their account (without logging out the first user) the automount mounts the folder with a red "No Access" sign on the folder. The only way to resolve it is to eject the mount and manually remount.
This is not the end of the world, but I would like to resolve this issue if possible, so that the users get a smoother experience. The way I tried to resolve this: I thought that maybe Netatalk does not allow the same user to connect more than once from the same IP, so I set up an additional user on the Ubuntu machine. when I connect to the Ubuntu server using the new user for authentication, the only share available for the user is their home folder. The other shares are not available.
I therefore tried to configure permissions using the AppleVolumes.default by explicitly giving all users the "allow" permission for all shares and restarting the Netatalk service, however the new user still has access to nothing but their home folder. How can I share the same shared folder between multiple users?
On other editions of ubuntu server I had no problem saving multiple users and passwords with htdigest but now it seems it is only possible to save one user and password.
Code:
sudo htdigest -c /etc/apache2/passwords directory user
When I add a second username and password for the same directory it overwrites the first.
I find FTP server software confusing in Linux. Using ServU for Windows for an example, all I need to do is to create users via the ServU interface and choose a folder I want that user to have access to and their permissions, and viola, they can connect to that directory, and that directory only.
But in the the land of Linux, it apparently can't be managed this easy. I have a web server with multiple domains, and therefore multiple users need access to their own web root. So with that in mind, what FTP server software should I use (there are plenty out there) and how would I go about to create a user per domain, so that they can log in using FTP to manage their site, and only have access to their own web root, and nothing else?
I want to setup a git repository, three of four users will contribute, so they need to download the code and shall be able to upload their changes to the server or update their branch with the latest modifications.So, i setup a linux machine, install git, setup the repository, then add the users in order to enable the acces throught ssh.Now my question is, What's next?, the git documentation is a little bit confusing,i.e. when i try from a dummy user account to clone the repository i got:
xxx@xxx-desktop:~/Documentos/git/test$ git clone -v ssh://xxx@192.168.1.104/pub.git
