Setting Root Password

Wow, I got my new Linux pc yesterday and it's very very fast. It's faster than my new MacBook.
So I go to the user account which also says administrator so I'm presuming that's the root owner?????? and I typed in my name and changed the password. The guy who sold it to me named the password user and the computer user. Yet when I go to the terminal my username and computer is still called user@user
How do I change the root password and computer name?

Hello Everyone,

I have a question about how to give sudo privileges to a user that log in via public key without password.

I created a normal user and I added this user to the "visudo" folder with ALL privileges.

when the user is logged in the system via public key and the user wants to become a root, a password is requested but i don't want to type the password.

Also to add the public key to the root it is not possible because i track the user log in in the system and if they log via root i cannot do that.

Thank you in advance.

Hi all,

I am slackware 14.0 user. Recently I face one problem. As a root i can change one of my normal user's (assuming Peter) password. However, when I login as Peter, and try to change the password, the system does not allow me to renew my password.


root@slackwa /etc# ls -la | grep shadow
-rw-r----- 1 root shadow 9 Nov 29 2013 gshadow
-rw------- 1 root root 0 Jun 20 2013 gshadow-
-rw-r----- 1 root shadow 2272 Apr 12 22:44 shadow
-rw------- 1 root root 2274 Apr 12 21:40 shadow-
root@slackwa /etc# ls -la | grep passwd
-rw-r--r-- 1 root root 2362 Apr 12 12:58 passwd
-rw------- 1 root root 2306 Jan 8 17:38 passwd-
-rw-r--r-- 1 root root 2305 Aug 11 2014 passwd~


peter@slackwa ~$ which passwd
/usr/bin/passwd
peter@slackwa ~$ ls -la /usr/bin/passwd
-rws--x--x 1 root root 68725 Sep 14 2012 /usr/bin/passwd*

peter@slackwa ~$ passwd
Changing password for peter
Old password:
Incorrect password for peter.
The password for peter is unchanged.

One thing I can assure is the password I input is correct. I have another slackware 14 running on Dell R410, but it does not has this problem.


Please kindly advice. Thank you.

Hi
When i tried to change the password for a particular user as a root by using usermod command I didn't see any error at that time.But later when I tried to login again it is not accepting the new password as well as old password.Why its happening?Any help....

I am using debian 7.7 stable and when I open the root terminal it asks for the password.

But if I open it again, I get the message: 'Granted permissions without asking for password. The /usr/bin/x-terminal-emulator program was started with the privileges of the root user without the need to ask for a password, due to your system's authentication mechanism setup'.

Oh, really? Because I don't remember setting up any 'authentication mechanism setup'.
How can I change this so the root terminal always asks for the password?
Do I have a trojan already? Because I installed the OS just a few days ago.

Thanks very much.

Hi, I downloaded an ISO linux file for my Vmware it was with a read me file that show the login details into the OS. Now have finished the installation of the ISO on my Vmware but the problem I have is it not accepting the login details that came with the ISO I download.
this was the login that came with the ISO:

standard user:
username: user
password: password

administrative user:
username: root
password: password
It not accepting any of it I want to know if I did something wrong or there is master login deatils I can use to get to the desktop.
Am a real newbie this is my first time of dealing with Linux your answers will be appreciated a lot. Thanks.

I have created a new user with "useradd" than changed the password with "passwd" (logged in as an administrator). After that I tried to login as the new user but couldn't. Error message was: "call to lnusertemp failed (temporary directories full?). Check your installation".

I currently use Debian 8.

I checked the home directory and couldn't find a new created folder for the new user (wasn't supposed to be done automatically by useradd?) and I checked the etc/password and there was the new user name inside it though.

What should I do? I really need to have more than one user on this computer...

Hi, I'm really a newbie when it comes to Linux, so please bear with me.

We have a working FTP using vsftpd with a pam.d database (by the looks of it).

I've found the list of users/password in the /etc/vsftpd/ folder called passwd, but they are all encrypted.

How can I change the password for a single user? I'm sorry I've been looking for over 3 hourw, still don't understand how to do this.

Thank you very much for whomever can help.

I have been getting permission denied issues when trying to log into as root. I have set my password and when I type su - root and enter in my password I keep getting either password incorrect when I know I am typing it in correctly or acess permission denied from su. Can anyone explain what I am doing wrong. I am trying to get into /etc/passwd for homework assignment and I get permission denied when logged in as my user. Any help will be great. I have in the past been able to logg in to root but now I cant seem to get into it. This is a new install of ubuntu 14

when a command is typed(i.e. /path/to/the/program), as a normal user, he should be able to run that command , execute that program as ROOT and log out root after the execution is completed.
Only one user should be able to do it.
Hence, I have created a new user vj and added the following command in visudo:
Code:

vj ALL=(ALL) NOPASSWD: /path/to/the/program

Now user vj will be able to typein the command.

What I need is that the program which is been called must run as if it is run by a root user,and when the program is completely executed, exit the root user.

How do I proceed?
