Server :: RHEL - Not Allowed To Have The Root Password
Dec 12, 2010
I have a server with 2 hard drives in raid for RHEL and 16 harddrives in raid 10 for storage. I was not allowed to have the root password just in case because "we don't give root password". A few days ago it crashed asking for root password for maintenance and had to restore the system to factory settings losing all user settings and updates (wich I paid for every year).
I'm not a linux guru but i can mount the system with a live cd, edit /etc/shadow and delete the root password but what I don't know is the consequence of deleting the root password. Can something go wrong after that? Can it have boot problems or something else? Can they set traps to prevent this?
Server is not connected to internet and it will never be.

To comply with standards I need to change the root pw every so often. However, I really don't have a need to know the root password; as the only thing using root, is for ssh authenticating via ssh keys. What I want to do is automate the root password change monthly via a cron job, to a random value. Is there a way to do this without knowing the previous password?

I am an absolute Linux Beginner who is being required to do a bit of admin work because the boss just fired the old linux admin. Unfortunately, one of our employees cannot remember her password to her email account and as such I need to reset it on our linux server.What I want to check is that this email account is actually a linux user account and I simply will reset the password for it using the passwd command from the root login. Is that correct?

I started a new job and they use LDAP here. I built a new RHEL 5.5 server and configured LDAP. Usernames are recognized but the password is not. I can chown a file to a user name but when I try to login as the user it won't accept the password.I know the password is correct because I can login to any of the old boxes and it accepts the password. I ran authconfig-tui to tell my RHEL box to authenticate to ldap.

When I installed the OS, I wasn't prompted to set the root password. Is this a bug, or did my install hose up?

Situation as follows: i do su to root, then i create admin file with
cat > adminfile
then i exit from root issuing exit command
i can see following adminfile options
-rw-r--r-- 1 root root 10 2010-06-16 16:25 adminfile
however, after executing rm adminfile it really gets removed
-rw-r--r-- 1 root root 10 2010-06-16 16:25 adminfile
[Code]...
As i see it - others have only read permision for that file so they shouldnot be able to remove it.. :/

While reading some papers on securing apache with selinux, I have tried to bind httpd to port 3000 expecting to be blocked by the selinux, since port tcp 3000 isn't on the http_port_t list. However I was able to start the service...
I'm preety sure selinux is enforcing. Also, if I bind httpd to tcp 81 selinux denies the start of the service, as expected!Did I miss something? Why is httpd allowed to start binded to a port that's not explicitly allowed?

sometime ago i have setup a nice Debian FTP server. and left the company. everything was working fine for about 5 month, administrator was able to login to root, do changes and manage system, etc. Suddenly he told me that he cannot login via PUTTY, the root user and pass say Access Denied.Looked all over the web for at least a REASON, but did not find anything. I suggested to go and do passwd reset, via runLevel 1. i hope this helps him. But i am still curious why all of the sudden, in a locked down room, where only one person has access root get disabled.

Yesterday, when I was installing Redhat Enterprise 5.4 on a HP server, I asked myself "how can I regain my access to the server if I happen to forget the root password?" I knew there must be a way. I consulted with my friend "Google". I'd like to share it here as my 1st post (too bad that I'm not allowed to paste screenshots)
1) Boot up the server, when you are at the "Red Hat Enterprise Linux Server..." entry, press "e".
2) Highlight the "kernel /vmlinuz...." line then press "e" again.
3) Type the word "single" to the end of the line (with an empty space before the word single). Press Enter.
4) Press "b"
5) System will boot. When you get the prompt "#", type "passwd" to enter in new password for root.
6) Reboot the system. Done

I have a Debian VPS webserver running a forum, and I'm currently looking for a secondary tech-admin. Since they'll have to have the root password for the server, I'm looking for a way to create a backdoor account that I can use to get in if they divulge the root password, or go crazy and lock me out. Is there a way to do it?

is possible to edited the default RHEL CD to have it automatically install RHEL based off of a kickstart file that I will store locally on the CD. My plan would be to put a cd in a server and have the OS automatically being installed.

I set up a servber on my local machine, & also PHp - Both working fine.I'm trying to load up MYSQL i have installed it, & *can* start/stop the server. however if I do anything else with it, I get this error :-
Quote:
root@gordon-desktop:~# sudo mysqladmin -u root -h localhost password MYPASSWORD
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost' (using password: NO)'
Query :-
1) How do I know MYSQL is actually active ? (apart from the message it says that its statrted (or stopped).
2) Is there a way to
a) Find out the usernames that are recorded on the MYSQL server ?
b) set / RESET the 'root' username (I know MYSQL root user is different to PC root user)
c) anything else I can do on the PHP / website code to see if MYSQL is working
(as yet, no tables / databases etc have been set up - as I can't get past this error message - I get the same error when setting up a database.)
Ps I did allow my usermname (when logged in to ubuntu) to edit / create files in the /usr/www/ directory (but it is still OWNED by 'root' - that directory)

Something has caused me to be locked out of root; the KDE login screen now says "root logins are not allowed." It's not as though I don't know the password--I set it up. I might have deleted something I'm not supposed to, because before this, root had also become invisible at the KDE login screen.

I'm really new to Linux so this will probably sound like a pretty naive question to most users, but how do you change the root password?To install Java, I have to type # su into Terminal,which then asks for the password.What's weird is that when I start typing a password, no characters show up. I don't know if this is supposed to happen or not.I've found a bunch of different sites on the Internet that explain how to change the root password, but none of them seem to work for my specific work station.
I've got Ubuntu 9.10 64 bit. In the GRUB boot menu, I can choose to boot normal or in recovery mode (I'm led to believe older versions don't have this option).I've tried typing # sudo passwrd into Terminal, but I already have a root password set up apparently, so I can't change it there.
