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.

# cat /etc/*-release
Red Hat Enterprise Linux ES release 4 (Nahant Update 8)

Normally I would run this command:
subscription-manager register --username 'username' --password 'password'

but I am getting:
subscription-manager: command not found

I am wondering, with using

# rhn_register

How can I associate my login and password to assign this system to my Red Hat account?

How can i extract my mikrotik V5.25 router password using mac address

CentOS Linux 7 (core)
Kernel 3.10.0-299.el17.x86_64 on an x86_64
local host login:kd
[kd@localhost ~]$

The above is what displays on a black screen.
The program was d/l to DVD and then installed on a usb stick and booted from there. No password.

This is the second installation. On the first, a pw was specified but at login, it would not accept input from the keyboard except the enter key which resulted in Incorrect Password.

Help would be much appreciated.

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.

Is there a way to elevate privileges in GUI?

For example, when trying to open a file that requires root to view, unlike Windows, where I would be presented with a prompt asking for admin username/password, Linux would just say that I need to be root to open.

AOA
