Ubuntu :: Change Umask On Per User / Group Basis?
Mar 25, 2011I've decided to move this question into a new thread since i haven't received an answer for 3 days. This question was originaly posted here: [URL]... I've already searched in google, however i wasn't able to find an answer that solves my problem... How can i change the umask on a per user basis so that each user can have its own umask to fit his needs? For example: I have four accounts on my system ex.
admin1 : admin,
admin2 : admin,
manager : stuff,
user : user,
-So now I want everything from the admin group to be by default set to 002 (so that every user that is in the admins group can have a full share (-rwx rwx r--) of everything that is created by the admins).
-Then the similar to the above managers shoud have 022 umask.
-And each of the regular users should have 002 or 022 or 077 it is up to the users choice.
I hope that i have provided enough info thorough the example.
Ubuntu :: Change Default DE / Window Manager On Per User Basis?
Mar 27, 2010I have a 9.04 machine that is used by the family with two accounts set up. One is mine with sudoer privileges and I prefer fluxbox. The other account is for everyone else and the rest of the family prefers gnome. Is there a way to set the default DE/windowmanager for each user so that each user simply has to login and be in their preferred environment?

Security :: REDHAT Missing Functionality - Force User To Change Password On Login?
Mar 16, 2011I have now been trying to find an answer for the following for a while and can't seem to get anything.On previous linux distros we had the option available "passwd -e" which allowed us to force the user to change their passwords upon the next login.s functionality however seems to be excluded from latest linux distros (currently using RHEL 5.4)...Does anybody know how the same effect can be achieved and perhaps any idea on why this option was removed as it was great for securing passwords

Jul 22, 2011I forgot the root passwd for linux (via the "single" mode) and, according to all confirms, did so successfully! I then try to log on to Centos as root, and I can't....it says "incorrect passwd"! So then I log on as another, regular, but not root, user, with that passwd, and boot up into Centos. if I try to "su" to root, with the new root passwd, again it says its incorrect. there is no "system admin" passwd set. I checked!. I need root access within Centos!

Mar 1, 2011I have got a RHEL 5.6 server configured to authenticate via a Windows 2008 domain controller via LDAPS.Everything is working fine, except from the following: When I create a new user in Active directory and check the option "user must change password at next logon", the new user cannot logon and gets an "access denied" message. In /var/log/secure, I find the following:
Mar 1 14:43:21 cpssvn10 sshd[5363]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=192.168.3.12 user=testuser2

Mar 1 14:43:23 cpssvn10 sshd[5363]: Failed password for testuser2 from 192.168.3.12 port 4583 ssh2
As soon as I uncheck the "user must change ..." option, the user can log on without problems. Also password change via the passwd command works.
General :: Grant Regular User To Locally Mount Partitions And Shutdown The Machine Without A Password?
May 28, 2011What I'm trying to do is to grant my regular user to locally mount partitions and shutdown the machine without a password. Here is what I've done to /etc/sudoers:
Code:
Host_Alias LOCAL = localhost
Cmnd_Alias SHUTDOWN = /sbin/shutdown
Cmnd_Alias MOUNT = /bin/mount, /bin/umount
<my_username> LOCAL=(root) NOPASSWD: SHUTDOWN, MOUNT
%wheel ALL=(ALL) ALL
My user is a member of wheel group and I want to type the password for each sudo command except for shutdown and mount. However I am asked for a password whenever I execute "sudo mount [...]" or "sudo shutdown [...]".
Ubuntu Security :: Unable To Deny Sudo Access To Regular User Account.
Dec 19, 2010I made a Desktop User account. When I went on that account, it allowed me to execute sudo as if I was an administrator. I don't know what might be causing this. I do have ufw set up and blocking incoming connections. Do you guys know what might be at the root of this?Also, when I used sudo from the user account (which I shouldn't have been able to do), I provided the password for my admin account.

Red Hat :: Cannot Change Root Password (let Alone Standard User's Password)?
Jan 6, 2009At the RHEL prompt, I entered the standard user's username/password combo. Linux displays a message box stating:"Your account has expired; please contact your system administrator."Next, I entered "root" in the username field and entered the root password (which expired also--keep in mind that passwords are set to expire after x days). Linux displays a message box stating:"You are required to change your password immediately (password aged)."When prompted to "Enter current UNIX password", I entered the new password (was that the right thing to do?); Linux displays a message box stating:"The change of the authentication token failed. Please try again later or contact the system administrator."I rebooted the system and got into command line mode; somehow I logged in as "root" (don't know exactly how, but needed to change the password there). At the "#" prompt, I type "passwd root"; Linux displays the message "Changing password for user root", followed by the message "passwd: Authentication information cannot be recovered.

View 3 Replies View RelatedUbuntu Servers :: SSH Chroot On A Per-User-Basis?
Mar 23, 2010I'm attempting to give a few buddies encrypted storage space through sftp using truecrypt.I have it worked out to the point where the truecrypt volume is automatically mounted when the user logs on, and dismounted when they log off.I would like to restrict each person to their individual home folders. This way, I can control exactly how much space each user is able to use (through the size of the truecrypt volume), while maintaining security through the network due to using SFTP.
I've been looking around, and the only thing I can see is restricting a large group of users to a single directory, this won't work, I need each person to be locked down to their personal home directory.My end goal is to have these volumes "mountable" in Windows through the use of Windows network drives (on a wide network, not through samba on local), or by using expandrive or a similar program. how I can lock these users to their respective home folders?
Ubuntu :: Access To Applications On A Per User Basis?
May 23, 2010I'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.
Ubuntu :: Cannot Change User Password
Jan 5, 2010I've tried both the GUI and the terminal to change my user's password and both are failing. I'm running 9.10 with current updates.
In the GUI, I type in the current password and it recognises it. I then type in the new password twice. Upon clicking change password it hangs.
In the terminal I use "passwd". I type in current password. I then type in the new password twice, but an error of:

I've even changed the new password to another something different (with NO special characters), and it still fails.
Are there certain characters I should NOT have in a password, such as /#/ or /;/?
Slackware :: Setting Timezone On A Per User Basis For Xorg?
May 23, 2011Slackware: 13.0
After having some problems with iptables not picking up automatically (without restart) the transition from winter time to summer time, and on advice from the iptables/netfilter mailing list, I've decided recently to go down the Unix way and set my hardware clock time to UTC/GMT instead of local time. I am, however, having some difficulty reconfiguring my entire machine to cope with this change.
1. I've used /usr/sbin/timeconfig - which took care of system wide timezone. After that, if I opened a terminal, du "su root" - and then check the date - it looks good. Doesn't affect though the logged in (non-root) user. Running "date" in bash window for logged (non-root) user returns wrong time (UTC) instead of local time.
2. I've added an export statement in ~/.bashrc, to set the timezone for the user account I use. That fixes the time for the logged in user, but only in the terminal. The time in fluxbox/X is still the UTC time.
Where is XOrg taking it's timezone for the logged in user? Do I amend/add to XOrg.conf? At the moment there is nothing about time zone in Xorg.conf (only contains few tweaked settings I've added to it - as I believe most of the rest is autoconfigured). I've searched - but couldn't find how Slackware configures timezones for individual users - aside from the timeconfig utility used during setup.
