I've got Ubuntu 11.04 installed. My users' home folders are only accessible to the users (e.g. chmod 770 /home/*), which means that GDM cannot access the /home/*/.face file. The permissions are configured (by default) to allow everyone access to the /var/cache/gdm/*/face files. However, the login screen will only ever show the user faces when I lower the permissions on their home folders to allow everyone, including GDM, access to the /home/*/.face files. How I can force the login screen to use the /var/cache/gdm/*/face files?
I tried to help my friend install Ubuntu 10.04 side-by-side with Windows XP on his Acer Aspire One netbook.Unfortunately, the installation process came to a standstill and it quit due to "unexpected errors". The second time I started the installation, I realized that the option for installing side by side was gone and that I could not mount the C: partition on Ubuntu. The error message is listed below:====================BEGIN ERROR MESSAGE======================Error mounting: mount exited with exit code 12: Failed to read last sector (299982847): Invalid argument
HINTS: Either the volume is a RAID/LDM but it wasn't setup yet, or it was not setup correctly (e.g. by not using mdadm --build ...), or a wrong device is tried to be mounted,
Original HOWTO can be found at: [URL]... So the other day I was in IRC and someone had brought up a problem where they created a new Administrative user, but didnt have rights to use sudo. Looked into the problem a little bit to figure out what was wrong, and it turns out that when you create a new user through the user manager (in kubuntu, anyways. Havent tested in Gnome.) the user gets added to the adm group, however, a quick look at the sudoers file shows that its looking for users in the admin group to allow the use of sudo. So, to solve the problem we do the following: If youre on the new admin user (which Im assuming you are) use the following commands:
Code: su [insert username of old account without brackets] sudo usermod -G admin [username of new admin account without brackets] exit
Then simply logout, and then log back in (not always necessary, but the easiest way to flush the permissions.)
Code: su [insert username of old account without brackets] Means were going to Switch User to the old admin account Code: sudo usermod -G admin [username of new admin account without brackets] This simply adds the admin group to the secondary group list for the new user Code: exit Pretty self explanatory
I found that if any usual user is logged into a NDS-tree, then _local_ root has full access to user's network shares, including the user's home directory located on remote Netware-server. Is it by design or have I missed something? Nevertheless in windows local admin has no access to network resources mounted of any other user. If you runas shell (as admin) then admin in principle can't "see" network shares which were mounted (connected) by other users - they are accessible ("visible") per session.
Take a physical user FRED. FRED is a linux user ( known by linux on his laptop ) FRED is a Samba user ( Known by samba on the samba pdc server ) When he logs locally (with username/password) on its standalone laptop (with no network), he is known as FRED:user. He access his data in /home/FRED/. When he logs through samba (with username/password) on the domain MY_DOM, he is known as MY_DOMFRED:MY_DOMdomain user. He access his data in /home/MY_DOM/FRED/. ) Is it possible that the human FRED has only one repository and have full access to its repository regardless of how it was connected. If yes, how to do it
2) If not, Is it possible that the human FRED has full access to /home/FRED/.............. and /home/MY_DOM/FRED/.
I'm developing an application in which one user must run java software that I'm compiling as another user. I wanted to give user A permission to see the bin direcory of my workspace, which is in the home directory of user B. I was wondering how can this be done? I gave the bin direcotry full read/execute premissions, but since it's in my home directory user A can't navigate to it.
I know there are a few ways I could get around the problem but they arn't very elegant. I was wondering if there is a simple method for giving a user access to a specific directory without giving access to all the parent directories. I tried symbolic link but user A still can't access it, and a hard link to a directory isn't allowed in Linux. I don't feel like making a hard link to every single file in the bin directory, and I'm not sure that would work anyways, since every recompile overwrites them.
I am trying to give access to ONE single user to start and shutdown tomcat server. The problem being, when I enter syntax: username ALL= /etc/init.d/tomcat5, /usr/local/tomcat/webapps, PASSWD:ALL This gives the user access to start and stop tomcat but also gives user access to start and stop other services within /etc/init.d - such as httpd etc... What is the proper way to give user access to start and stop service, and limiting that power to only one service....
Which sets ownership to all files created in that folder and I assume the subfolders to my group "ftp-users". However the file permissions when created are:
-rwx------ 1 test ftp-users 0 2010-07-04 13:58 TestFile1.txt -rwx------ 1 test ftp-users 0 2010-07-04 13:58 TestFile2.txt
I want the ftp-user group to have full access to these files.
Apache by defaults points to /var/www/eachdomain. I need to be able to give users ftp access to /var/www/specific domains.
It seems that if I change the owner of /var/www/specificdomains/ to the user in question, then www:data no longer owns the directory and Apache starts to have issues..
What's the best way to set this such that I can allow users to FTP into specific directories, and still have www:data own them? I'm currently using vsftp, but that can easily change.
It's been a few years since I last installed Ubuntu. I searched the forums and can't seem to find the answer. I want to be able to do a "su root" and have root access. I know Ubuntu wants you to do the sudo command, and I know you can really mess things up being root. I know I got this to work before. What do I need to do?
I'm wondering if it's possible to control what applications are available to certain users on a per user basis.
My motivation:
I have separate logins for audio production and general admin. Under Applications > Sound & Video I have tonnes of audio apps, but as I never use these under my general admin account, there's little reason to list all of them.
how is the applications menu configured? I'm wondering because I'd like to create some custom sections.
The goal is the following: I want one samba network share with all my family data. Multiple users should have access to this share from Win7 pcs but not all folders should be access able by everyone. The old windows server managed this by changing ntfs rights for these folders.
I've installed Samba and this recommended gnome utility (Ubuntu 10.4). First for testing I made a samba share with access right for everyone. Everything fine on Win... Then I only allowed for my user. Also worked after a little bit of playing with the global samba settings and the pw encryption... Then I created a new ubuntu user and configured a new samba user with the connection to this ubuntu user (like described in many tutorials using the samba config tool). I changed the access right of the samba share to allow the new user also but no connection was possible. At this point the original user was working from the same pc without any problem.
I started thinking of the windows time and decided to search for the file system rights like it was with the ntfs. I'm using ext4 by the way. I made chmod 777 -R from the new users login... (i'm not sure why there is no user dependency for chmod) I used chown -R but it seems that there is only one owner allowed so I switched back to my main user... I installed an additional feature called ACL and was able to set users and groups for the root folder but there is no possibility to recursively change all subdirs. I used such a ACL gui extension for gnome which is in the ubuntu repository to do that. It also wasn't helping for the problem that the new user has no access to the folder (even if I change the rights manually)
User A & B have access rights at least for the root of the share. Both users have a ubuntu and a samba account. Only user A is working with samba.
I want to create a limited user, such that the user should only have the access to usb drives, cd drives and internet. And also I want to restrict the user from deleting the files from the system. How to do it..?
I'm wondering if there's a way so that several people can log onto my computer at the same time. When they connect it goes to the login screen and they choose their account and log in. Everybody has a different account and sees a different desktop. Is that possible?
I'm using Ubuntu x64 10.04 edition. How can I set only one particular directory (and it's contents) to be accessible to a user while make everything else inaccessible for him? I already added the user by using adduser command.
I have configured proftp. I want to access by the particular user. I have configured file, but not able to login. message getting login failed.
[root@localhost ftp]# vi /etc/proftpd.conf # Use this to excude users from the chroot DefaultRoot ~ !adm # Use pam to authenticate (default) and be authoritative AuthPAMConfig proftpd AuthOrder mod_auth_pam.c* mod_auth_unix.c
is there any possible way to hide currently running processes from an user? This means I do not want him to know about what programs/processes does any other user but him run. In short words if that user runs 'ps -aux' he should get only his processes.
When I create folders in a PHP script fom my website, the folder is created but has owner "33". My ftp user have an other "Owner ID" than this. So I can't delete or edit the files that is created. I'm running Ubuntu 10.04 on a VPS server. ISPconfig3 proftpd I think I have LAMP (it was installed with a script from my hosting company).Also the safe_mode is off.
I would like to set up a user account with no network access. Reason is that sometimes my little daughter plays with the computer (for example watching movies on dvd's) and I want to prevent internet access in case she plays unattended. Is there a simple way to do that? I am using ubuntu 10.04.
I have a Lucid Ubuntu installed on my home PC with two user accounts, AmHero and simple. I would like to have all internet access disabled when my kids login with the 'simple' userid. And yes, internet should work when I login using AmHero. I tried this:
[URL]
..but this does not work and gives some errors on the terminal.
I can paste the errors, though I am not sure this will even work as I found this in an old post.
Cannot seem to use my mysql password, keep getting the error "Access denied for user 'root'@'localhost' (using password: YES)" So I tried checking my password using mysql -u root -p and I get the same error as above. I've tried accessing mysql with skip grant tables disabling the need for a password so I could reset my root password. After going through the necessary steps I still get the error above when typing my password in for mysql.
i want to allow some friends to ssh/sftp/scp into my system but i only want them to have access to my external hard drive (/media/externalHD/), and i dont want them to be able to delete or add anything, only download.i have found instructions on how to limit a user to his/her home directory and thought about just creating a user with the home directory /media/externalHD but idk if this will work and im afraid i might make a mistake and delete 800gb of 'files'
My laptop is running Ubuntu 10.04. I have my own account (custom) and 1 desktop user account.
When I log in under my account and switch to the desktop user account, I can connect to the internet. However, if I start the laptop and log into the desktop user account first I get no internet connection and the same when I switch to my own (custom) account. What gives?
I managed to make an old parallel port scanner work in ubuntu 11.04 with SANE. Everything's perfect but one thing: scanner applications work only if they are executed as a root.After further researching, I've found the cause is that only the root has read and write permissions on the device /dev/parport0 which is my parallel port. If I set the right permissions giving sudo chmod a+rw /dev/parport0 I solve my problem, but just untill next reboot... the system resets root only permissions at each restart. I would like to make that change permanent... what can I do?
cat /etc/group | grep www-data | grep chad chad:x:1000:www-data
