Hi, I forgot my password so went into root to change it.
From grub menu, Ubuntu : advanced options : ubuntu recovery : network : root
input passwd then typed in a new password and re-entered password. rebooted.
Tried to uninstall Firefox from software centre but the new password was not accepted for authentication.
Could anyone advise what the problem could be or suggest what I may have done wrong. The password appeared to be accepted ok in root. Thanks
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.
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
Hi everybody,
I used to be a Linux developer, but I have not used Linux or anything UNIX-like for a long time (more than 10 years). I had it installed by someone else and assumed that the root password is not set. Turned out - it has been. I can logged in as "owner" because I have guessed the password ("password") but no such luck with root. Can anything (other than reinstallation) be done? Is there some default password that root gets at installation that someone at this forum knows? Any other suggestions?
Thank you in advance.

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?

How do I change the root password and computer name?
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.

My version is: ubuntu 14.04 lts. I was not able to change the root to read-write so I could change the password. Nothing worked unbuntu does connect to my wifi.

I found an old laptop that has centos 5.5 installed. I reset the root password, but I need to reset the gui password. Is there a way to view this password or reset it? I have not worked with Linux over 5 years and am rusty on all the commands
Hi All,
Please can someone assist me on this, I enabled Selinux on Ubuntu 14.04 server and it's disabling ssh remote login for all users including root.
From the ssh terminal I get the following error:
ssh root@192.168.x.x
Last login: Wed Mar 25 12:39:02 2015 from 192.168.x.x
/bin/bash: Permission denied

This avc is a constraint violation. you would need to modify the attribute of either the source or target types to allow this access.
possible cause is the source user (system_u) and target user (unconfined_u) are different.
possible cause is the source role (system_r) and target role (unconfined_r) are different.
possible cause is the source level (s0) and target level (s0-s0:c0.c255) are different.
allow sshd_t unconfined_trocess transition.
Please how can I make this changes to take effect.
Thanks in advance.
