General :: Mail Server : Reset The Password For It Using The Password Command From The Root Login?
Jul 23, 2009
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?

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 am trying to set up a webserver with apache, mysql and php on a old pentrium 4 computer. When I tried to setup my MySQL password, I created a password with punctuation in it. MySQL didn't want the password and gave some error about BASH. I tried changing my password again but now I constantly get the error that I am unable to login. I tried all the possibilities with the password I entered before but i just can't login to MySQL anymore. I found some help sites on how to reset your password by running MySQL in the safe mode but that didn't work for me. Can anyone help me resetting my password? Next time i'll use a pass without punctuation Every help is much appreciated! BTW, I also tried uninstalling MySQL with yum (yum remove mysql) and it uninstalled, but when I installed it again the password was still there

I have inherited a Compaq Armada 1592DMT that has Debian GNU/Linux (tiny) on its hard drive. After bootup there is a dialog box asking for login & password. Two things I have no way of answering. So how do I recover them? I do not have the faintest idea how Debian Linux works, nor how to Bash Grubs, I'm just an old Windows button pusher.

I have forgotten my root password for MySQL, what can I do to recover it, I've found a few guides but they don't work on the newer versions of Ubuntu.I am running on Ubuntu 10.04 server so MySQL is an upstart job so the methods I've seen with launching it without the access checks haven't worked for me

I have forgotton my root password for mysql. I followed some instructions on a website and now I am not sure what i have done?Basically, when I now try and start mysql I get a notification that i have converted the init script to an upstart. I dont know what this means.
Since the script you are attempting to invoke has been converted to an Upstart job, you may also use the start( utility, e.g. start mysql mysql start/running, process 20301.

I forgot my root password for mysql, and after some searching I found several solutions to fix it. But none of them seem to work.I tried this article http://ubuntu.flowconsult.at/en/mysq...root-password/ with starting mysql with the --skip-grant-tables option. The problem is that nothing happens, it just hangs.Also tried the the --init-file option, that one runs fine, at least it returned to the command line. But the sql query in the file to which it point doesnt seem to do anything. The password wasn't changed to the one I specified in the sql file.Any idea what could be going on here, and how I could fix it?

I'm trying to figure out why my industrial appliance (x86, running kernel 2.6.21.7 and OpenSSH_4.3p2 / OpenSSL 0.9.7m) accepts ssh connections without asking for a password (even for root)!When I log on to the local console as root I have to enter a password but strangely this prompt won't appear using a ssh connection (although I'm not using any client certificates).Of course that not acceptable but I just can't find the related configuration entry to disable this "password-less" authentification.Is this related to the sshd or has it something to do with the PAM module?
- Update ->
While looking at /var/log/secure, I've found the following lines:
Jul 18 16:55:07 localhost sshd[5712]: Accepted none for root from XXX port 6393 ssh2

Can someone assist me with recovering/resetting the password for Root via Single User Mode in CentOS v5? I've modified the kernel line using Single, S, and 1 but it appears that these commands are being totally ignored as the server continues with the boot process and displays the GUI logon screen. The server in question is a VM box running on ESX v3.5 U4. The person that created this VM is no longer employed here and I've exhausted everything I know regarding Single User Mode.

Being able to reset the root password by booting into single usermode by editing grub. This is a MAJOR flaw. I know it makes no real difference against internet bourne attacks, but even so I must say I found it shocking. The only way I've found to stop this is to encrypt the entire HDD, so noone could get into single user mode without first knowing the encryption key/password.

In Ubuntu 10.04, I logged in as user1 and when I open a new terminal and issue any command it is asking password.user@ubun-laptop:~$ sudo ifconfig[sudo] password for user: It is asking for password only for first time.From the next command onwards it is not asking.Can some one please tell me if it is possible to issue ONLY ONE COMMAND, in which even if the password request comes, it will automatically fill the password.Just like "ps -elf | grep NetworkManager". I am expecting any combination of commands in a single line, so that password is filled automatically IF PASSWORD IS ASKED. If password is not asked, the command must be executed.

I edited fstab to automatically mount my windows data partition on boot, but I screwed it up by not specifying the file system type, however that is not the problem, I was able to fix that easily. The problem was that when it failed to mount the partition, Debian automatically entered root and I guess that is to be expected in order for me to fix it, but I never configured a root password and it just gave me full root access without asking any password, not even my user password. I though that was strange so I set the root password and sure thing it asked me for the root password this time without automatically logging into root....
I then tried to lock the root account to see if it will ask me for a password or not, it did but of course I wasn't able to login as root because it was locked now and I was left with no way to access the system. I had to fix fstab from a live cd so that I can login normally as the user....
I didn't know what to search for or if that is the expected behavior if you don't set root password during installation, but it just seemed a bit strange to automatically enter root when you specifically disable root login during installation...
