Stories similar to [ubuntu] a peculiar situation without an admin user

I have windows Vista on my HP laptop. The user administrator and standard accounts have always acted wierd.

I have Ubuntu 12.04 LTS installed and have read many articles on finding a way to change the admin password as i forgot it after installing it a while ago. I have 2 users on this comp which i know the pass to 1 but the admin 1st user i can no longer get into. I have tried many ways like going through grub, root and trying to unmount.

I'm able to SSH to my server (CentOS 5.9) using an admin account with sudo privileges:

$ ssh admin@myserver Last login: Wed Feb 27 19:23:11 2013 from [IP ADDRESS] [admin@myserver ~]$

Then I can su to root:

[admin@myserver ~]$ sudo su root [sudo] password for admin: [root@myserver admin]#

But I can't su to another user, and the su command is not telling me why:

[admin@myserver ~]$ sudo su

Just as the title says. Why am I required to input my user password to launch this program? I am using 10.04 Ubuntu and this requirement does kind of annoy me.

I like making a second account that can admin the system, and my main account has the admin option disabled in the 'Users & Groups'.

I'm struggling to get to grips with passwords. I've reinstalled twice to try to sort it but still have problems. I've learnt not to try to get rid of passwords. The current problem is that when I created an additional account (a standard one) it didn't ask me to create a password, so I didn't. I clicked to log on automatically.

Does Screen OS support password policy to enforce the admin or user password change on a periodic basis

As per the current implementation for the password policy, Screen OS only supports to enforce a minimum length and a complexity scheme for administrator (admin) and authenticated (auth) user passwords. How ever there are companys who require the firewall to enforce a admin or user password cha

Amazon EC2-instance: I made a user 'admin' and copied ec2-user's keys with proper permission. After successful login, i tried to do sudo su for root access, it says 'admin is not in the sudoers file. This incident will be reported.'

However i can do sudo su with ec2-user account and can gain root access.

What is sudoer file?

Security bug in cPanel login 51 weeks 6 days ago

Hi,

turns out this is probably the easiest way to report a problem...

You have (what I'd consider) a security bug in your cPanel login system.

Hello, I am attempting to connect my new Brother HL-2230 printer over CUPS. However, when I try to log in to http://localhost:631/admin it asks me for authentication. When I enter the user name for my administrator account (limao) and password, it reprompts me for my username and password again. using

Code: # lppasswd -a limao Enter password: Enter password again: was no help at all.
