I followed instructions to enter single user mode by adding single at the end of kernel line but after that it doesn't ask for root password but brings up the sh# prompt. Isn't that supposed to be insecure? I understand for this the grub password can be applied but even after adding "single" it should ask for root password..or it should not..??

in ubuntu 10.04 how to get into single user mode with out entering the root user password
View 1 Replies View RelatedCan 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.

View 1 Replies View RelatedI need to recover the root password or reset it. For this, I am trying to follow the following steps to get into the single-user mode & where exactly I am getting stuck: 1. Reboot the machine2. Press <esc>3. At the boot loader screen, i have 'Red Hat Enterprise Linux Server ($version info)' highlighted. 4. Simply pressing 'e' (for editing) does not work (does nothing). 5. I have the option to press 'p' to enter boot-loader password and then go into the single user mode.What if I don't know the boot loader password as well & I want to get into the single-user mode WITHOUT using a boot CD? Is this possible? If so, please share the procedure to do so.

View 3 Replies View RelatedMy linux workstation recently crashed. After rebooting, Linux (Red Hat 5.3) will not boot properly and automatically went into emergency mode or recovery mode i think. I can still see my /home/user/ and all the files inside.I boot from CD to rescue mode and tried mounting read-only the /dev/sd5 which contains the files in the crashed hard disk to try to copy out my files but mounting was unsuccessful (invalid argument). I checked the filesystem type using fsck -N /dev/sda5 and shows it to ext2. i tried to mount another known working hdd and was successful.
My question is why in emergency mode, the crashed hdd is able to be mounted automatically as read-only but cannot be done in rescue mode thru a bootable CD?Is there any special mount options used in emergency mode?I also cannot copy out in emergency mode booting from the crashed hard disk as everything is read only.
I just tried ubuntu 9.10 in recovery mode i came to know that i can change root passwd without knowing the password then i can change password of every user by logging in as root
View 2 Replies View RelatedMy Ubuntu desktop crashed last night after I accidentally bumped into the CPU box. Right after I bumped into it, it restarted automatically ... then it ran disk integrity check, also automatically ...
The issue is that I can NOT log into it. There is no way that I could enter my password. Though I could telnet into it using my laptop (I have set up telnetd into this desktop before).
I am trying to search for similar issues in this forum but I could not find one that is really like this.I have all 5 years of work in the hard drive.
The two images below shows the issue it had done.
This is my login screen (note: whenever I click "nd-desktop", it doesn't give me prompt for password.

I've created Oracle Enterprise 5 Virtual machine. It was running fine but not sure what went wrong and now when ever I reboot the machine, it goes to single user mode. If I enter "init 5" command it boots to multi-user X11 mode without any problem.I checked inittab file and default line has id 5. So it looks OK. What else can be wrong?
View 15 Replies View RelatedI'm running debian lenny. Suddenly when I rebooted my system I was unable to login. I type root and the password and it tells me the login is incorrect.If I boot into single user mode, it accepts the password just fine. Looking in the /etc/shadow file, it appears to be fine as well.Running passwd to set a new password sets a new password just fine, i can login to single user mode with the new password, however, I cannot login at a higher runlevel with the password.
If I delete a password in the /etc/shadow file, then try to login as that user, it simply says "Login Incorrect" without even asking for a password.

View 2 Replies View RelatedI have this dump script that performs either full or incremental backups depending on the day of the week. From what I have read, when using dump you should drop to single user mode to help prevent the backups from being inconsistent before you issue the dump command. What I want is the script to drop to single user mode, perform the backups using dump, and then go back to runlevel 3 after the backups complete.
I know when you enter init 1 to drop to single user mode, but doing so within a script reboots the computer and drops it to single user mode and the rest of the script doesn't complete.What would be a good method for me to be able to accomplish what I want to do? Do I need to run other scripts that would call mine?I am running Centos 5.4
