CentOS 5 :: Change The Resolution Of Single User Mode?

May 31, 2009

At least I think it's called single-user mode. I don't have a GUI for my CentOS install. It boots up to a terminal. The text is too big though. Is there any way to reduce the text size?

General :: How To Change To Single User Mode In Dump Script?

Apr 26, 2010

I 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

CentOS 5 :: Recover / Reset Password For Root Via Single User Mode

Oct 20, 2009

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.

General :: Emergency Mode Can Mount HDD With FS Error / Not In Rescue Or Single User-mode

Dec 1, 2010

My 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.

Ubuntu :: Get Into Single User Mode In 10.04?

Sep 7, 2010

How do I get into Single User Mode in 10.04?

The grub menu seems to be gone in 10.04, and the computer boots in 2 seconds. It's great that it boots fast, but there has to be some way to specify boot options?

/etc/default/grub says the timeout is 10, but that doesn't seem to be the case.

General :: Always Single User Mode

Aug 10, 2010

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?

Server :: Cannot Get Out Of Single User Mode

Mar 18, 2011

I am running redhat ES 5 on a dell server and recently, I ran into a snag where I was able to reduce a partition (ext3) but could not run resize2fs (mismatch between physical and logical blocks (i never found a solution to this). In any case I decided to log in a single user mode (appended 'single' at the GRUB loader prompt) and now I am always taken to this single user mode every single time I reboot and can't seem to get out of it. I have tried init 5 (runlevel that the system is set to boot into by default) but that does nothing (no message on the # prompt).Of course, I have 2 problems here:

1) partition issue
2) cannot log out of single user mode.

General :: Can Only Login To Single User Mode

Mar 22, 2010

I'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.

Debian :: Force Single User Mode On Sun Ultra 5

Apr 26, 2010

I have successfully installed Debian on a Sparc Ultra5, 270MHz SparcIIi CPU, 384MB RAM, 40GB HD. However, once Debian tries to load Gnome (right before the login screen) the screen goes blank, and so the machine becomes unusable. I booted of the NetInstall CD, into rescue mode, and executed a shell, but apparently there is currently a problem when running nano from a live CD, so I can not edit the xorg.conf file when I boot the live CD. So, I would like to just boot the install into single user mode, but I dont know how. Currently, when the Ultra5 is powered on, it tries to boot with command "boot", so I hit "Stop A". From there I type "boot Disk1" to boot Debian normally. To boot from a CD, I would type "boot cdrom" So any idea on how I can boot from Disk1 in Single User Mode?

My only other idea is to hook up another monitor I have which may be able to deal with whatever resolution Gnome is defaulting to. However, Id rather just boot into single user mode.

I 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.

Debian Configuration :: Exiting Run Level 1 (Single User Mode)?

Feb 11, 2010

I'm running Debian Lenny. When I exit run level 1 (single user mode), the system automatically continues into run level 2. I have browsed the init scripts and have yet to determine how this "magic" is performed. I would be grateful if a local guru would point me to how the scripts automatically proceed into run level 2 when exiting run level 1

General :: No Prompt For Root Password After Attempting To Enter Single User Mode?

Jul 13, 2011

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..??
