I often put together complete computers from spare parts. When I do, I put Linux on them and put my name as the root user. However, I don't build these to keep them for myself.....I usually end up giving them away to someone who needs one and can't afford to buy one. What I would like to do before givi9ng them away is to change the root user name to their name. How can I do that? CAN I do that?
Is It possible to change a process running in root-user to non-root-user by setting suid / uid / euid / gid etc... I so please instruct how, when and wat to set in order to change a process running in root-user to non-root user
I am using mint 8 for a 2 weeks, I am noob to linux but I like Mint than any other linux distro which is great alternative to windows. I have a problem regarding password reseting.
1. My laptop automatically get logged in without asking user name and password.
2. I tried to change password for newly created user and root user using graphical way but it does not work.
2. I can perform administrator task using only OEM user which is default inbuilt user of mint.
How can make my laptop to ask password when mint get booted? How to change password for other users?

I am running Fedora 12 as Guest OS in VMware Player. I installed Fedora 12 by using a Prepackage VM . The root user name and p/w was supplied by the person who made this appliance. Is there way for me to change root user name and pw
For a user on a Linux host, I need to make everything inaccessible besides his home directory. I have heard that this is usually done by changing the root directory for the user (and setting it to the user's home directory), however I couldn't find the way to do it.
I thought about the chroot command, but it seems it just runs the specified command, considering the specified directory as the root directory. So it seems chroot is not what i need. So my question is: what is the command which changes the user's root directory?
I was unable to change the permissions for root node and for other users also. WE have tried all the possibilities like chmod and chmod -R 777 filenem. But we are unable to change that.
I need to edit the system time as a not-root user. I am carrying out the following actions in my program.
1. Read the User Id of the process. User_ID= getuid() 2. Printing Capabilities(Permitted, Efffective, Inheritable)of the process 3. Setting UID = 0, using setuid(0) 4. Calling the prctl(), function to keep capabilities 5.Switching the UID from root to User_ID of the process 6. What we have now is a process with root capabilities as a non root user 7. On printing Permitted, Effective, Inheritable capabilities, I get the following --> Permitted = 0xfffffeff = Effective Inheritable = 0x0; with UID = 1001; 8. I then try and set the system time with --> system("date -s 10:00"); 9. I get an error: date: cannot set date: Operation not permitted 10. I am unable to understand as to why I cannot set the time even thought the capability bit CAP_SYS_TIME in the Permitted and Effective sets are SET.
I have Slackware 12.2 installed on my computer, as well as a Windows Xp. I have a hard drive named '/fat-d', which is formatted to be 'fat' and is normally used under XP. This drive can also be accessed under Slackware, both as root and the normal user.I can not write to the directory '/fat-d' when I am not root, it is normal since 'ls -l' shows that its owner is root and other users have no permission to write. The problem is that, when I tried (as root) to change the owner to the normal user:# chown [normal_user_name] /fat-dI got an error: chown: changing ownership of '/fat-d/':Operation not permittedBut how can the root have no permission to change the owner?
I just tried ubuntu 9.10 in recovery mode i came to know that i can change root passwd without knowing the password then i can change password of every user by logging in as root
This is my 6th install of Fedora, begining with Fedora 4 I have had very good luck with all until 9 and I lost all data on drive by my bad clicks in a frustrated session. Now I have a great install of Fedora 10 with the exception that I fouled up and typed in a user (myself-'andybill') and am finding out that the work I need to do cannot be maximized by operating in user - andybill, I need to be super user. I have just moved and have not done any collaboration with our senior partner in a data development start up that he is the intellectual property in deed and law. For me to get back on track my using this OS I have to be master of all libraries, drivers etc. I am a nu-b (only 2 1/2 years, with no computer science background. This explains why I need step by step commands without abbriviated lingo-So if I can remove myself as andybill, make all root
At 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.
I no longer have access to my root desktop. On a session I attempted to change the root username but i apparently assigned it a wrong directory that does not exist. When I rebooted with my new root username, i was instead recognised as a simple user (no root privileges). I tried the console to change to "old" root but root password is not accepted and there is no way to access to sudoer files. it seems that inserting a new username requires root privileges and i am back to square one. Simply logging with old root username and password after restart gives me a blank screen with nothing on it and cannot even reboot.
i used opensuse 11.1 ...there is option for root user to create password for root...but for ubuntu i did not find anything like that...so how can i create root password....or how can i use root
A friend of mine has told me to set a root password and use root (f.e. switching to su in terminal and work with root rights instead).Is there any way to unset the root password? I know how to use sudo now.
i am having problems with privileges i have created a new user with my name, but i cant get root privileges on it. i need the same privileges as the root profile.
i just installed linux mandriva 2009. i set password for root and created a user account. when i try to login as root, after logging out as user, it does not allow me and gives the error "root logins are not allowed". even it does not show the root account. if i try to go to root from konsole terminal using su root, it allows to enter as a root but when i try to start the GUI with startx it gives error.not sure what to do and why i can't see my account in GUI mode
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.
I created a chroot jail in /SECURITY/Jail. But when I used the command 'sudo chroot /SECURITY/Jail' to enter the fake root, I got an error message likegroups: cannot find name for group ID 105groups: cannot find name for group ID 119.
Accidentally I changed the ownership of all the directories under / to my own instead of root:root. Now I am unable to use sudo and many bad things are happening. Is there a way to revert the changes or change the permissions again to root:root or make sudo work ?
This netbook only has a user with non-administrative privs on it and root user but I do not have root's password.Is there a way that I can create a new administrative user of change the current user's group so that it can do sudo commands or have more privs?
Now I know that in order to change the colors in your terminal you have to play around with ~/.bashrc But the effects don't stay in place after a change-root is taken affect. It just reverts to black. Is there any way I can change that too in .bashrc?
I want to add 50 new users, not on the server yet I want to add them all to group Accounting - with 1 option, not user by user I want to setup a default password for them all, and have it say something like 'You must now change password or no access will be permitted' Any other options I also want to do once, not for each user?
I'm looking for a Linux command that can change ownership of all files belonging to a given user,preferably in a targeted directory, to another specified user. My dream command would look something like this. chuser -R --olduser tom --newuser jerry
This is my scenario... I have a backup file (.tgz) with user and group information preserved in it. It was taken from a web server running Apache and MySQL. The files in the backup are from across the system and contain files from several different users and several system type accounts and it is key that when restored on the new server the settings are not lost. The problem is that the users on the machine the files are being restored to don't match the ones in the backup file. For instance both machines had a MySQL user but they have different user ids and there are several user ids that existed on both machines that belong to different users. This means there is no way to sync the users on the new machine to the ones on the old machine. I can find all the users files with the find command like this...
find /decompressed-backup-dir -uid 1050 or find /decompressed-backup-dir -user tom
If, as I suspect, there is no way to do what I want with a single command then perhaps there is a way to pipe the results of the find command to another command to handle the ownership change?
I could do this with a PHP script but there are 4GB and tens of thousands of files in the backup so I don't want to use PHP or Perl but I would be happy with a shell script that could handle it.
I'm very new to Linux, i'm running Ubuntu and i'm trying to install a program. In the instructions it says "Check that you ARE NOT root, never run similar tools as root! just change file permissions". How do i check if i'm root or what am I supposed to do here?
