can anyone tell me the difference between "sudo shutdown now" and "sudo shutdown 0"
i know that "sudo shutdown 0" will shutdown the system in 0 seconds. but when i run sudo shutdown now my system goes into the maintenance mode?? what is maintenance mode??
I cant shutdown without running sudo shutdown. When I try to use the default gnome shut down it takes me back to the logon screen. Fresh install today and I've had the same problem on other installs.
View 9 Replies View RelatedI've added entries to my Openbox menu labeled Reboot and Shutdown. Problem is, reboot and shutdown h only work as root, and I never login as root. I've tried su-to-root -c reboot, but the menu entries remain unresponsive. I do not have sudo installed because I feel it is a security issue. However, I found that sudo reboot works with the menu entry, but only if my account is set to use sudo without a password in /etc/sudoers. I use tint2 as my panel, but have had no luck with finding a shutdown/reboot button.
View 4 Replies View RelatedIt is my understanding that they do the same: they ask for my password (if I am allowed in /etc/sudoers), and give me a login shell as root.
Is there any difference between them?
sudo su -
sudo -i
Also, what's the difference between
sudo su
sudo -s
I think that they both ask for my password, and give me a shell with my old environment variables.

Ubuntu installed after Win7. Dual boot Win7 and Ubuntu 10.04, shared NFTS partition for Downloads and Documents, Grub setup to load Ubuntu by default. I can use the option to hibernate in Windows (but it is disabled by default). I would very much like to enable the "Hibernate" function on this machine, but there is no option for it in the menus. "sudo shutdown now" in a Terminal results in a screen that resembles the login screen background, but the machine is completely irresponsive and must be silenced by long-pressing the physical power button. When I use the GUI to shut down, everything works fine. Perhaps related: When waking the machine from the screen saver, the login window does not turn up before I press the "Esc" button. I am using a standard Gnome screen saver. Perhaps related: The Grub boot screen is getting more and more options every time the Linux kernel is updated.
I have installed a cluster computer with 10 nodes . The manufacturer is HP . All nodes and the master node have redhat enterprise linux installed in them . When I shutdown the nodes from the master terminal using "shutdown -h now" they get shutdown . But they dont get completely turned off . This issue bothers me when the power supply is given , all nodes boot up simultaneously generating a huge heat .
Thing to note : When we shutdown our PC they get completely turned off . When the power supply is given , a press on the Power On button is required to boot the system. But , why does it not happpen in the case of cluster? Is there any other way of completely turning off the nodes from the master terminal ?
They both appear to do the same thing, except sudo won't ask me for a password....?

A day ago I finally got around to upgrading the PackageKit installation that had been sitting for a week and a half, so I found a new upgrade for sudo available - the one that gives the sudoreplay command, I forget which version number it is exactly. When I try to use the sudo command I get this notice in my terminal:Code:Can't open /var/db/sudo/me/1: Permission deniedI didn't get it before. What do I have to do to make it open? I'm using SELinux in enforcing mode if that helps.

I cannot locate shutdown log for Linux shutdown to check various activities carried out during shutdown. I can view Startup Log which is availble on console>Applications>System Tools>System Logs.
I have included Shutdown/Startup in dbora, so that Oracle 10gR2 Shutdown/Startup will be automated during OS Shutdown/Startup.
I want to check Shutdown log because Oracle Shutdown was not running, as from $ORACLE_HOME/shutdown.log contains no entries, where as startup log contains latest startup details.
That means here 2 issues are there. One, I want to locate OS Shutdown Log and the other being Why Oracle Shutdown not getting executed.
Ubuntu will randomly pop up the shutdown menu and then shutdown.It seems to happen when im in firefox and typing and it has been difficult to replicate. I dont think it is a temp issue since watch sensors shows temmp of 40-50C. Someimtes it happens every minute someimtes i can go 10min without it happening.

View 8 Replies View RelatedI am new to fedora (been using debian based distro's for the longest time). With the new release I decided to give FC13 (The kde 64 bit spin) a try. I told it to wipe my entire hdd and encrypt the partitions. The partition manager made a few LVM partitions which I assume are encrypted.
The problem I am having is that if I attempt to use an application that would normally need root access to run, I am not prompted to enter my root password. Instead, I am required to logout and log back in as root. Is there a way to make it so that FC13 will prompt me to enter in my root password so I do not need to log in and out? Or is there something Different I should have done during the install process? Also, what is the terminal equivalent of "sudo" in fedora, or is it still sudo/KDEsudo
I also have not used SE Linux before. Do I need to manually enforce the permissions for my applications and generate my own profiles for it, or is that done automatically?
I did a live upgrade from 11.3 KDE and observe a following issue.When I press the shutdown button on the laptop it initiates the shutdown and shuts down fine but after a significant delay of time (something like 30 seconds). When I click the shutdown button in KDE it initiates the shutdown instantly. This was not the case in 11.3 where the shutdown worked the same regardless of the method that triggered it

Further to this LQ thread which Tinkster solved by suggesting the last command (thanks Tinkster) I have been exploring last -x reboot and have found that the reported duration is incorrect for the last reboot and shutdown when a old wtmp file is used. Not having a record for the following shutdown, last assumes that the system has been up until the current time and similarly for the shutdown.
The output comes in time order, latest first, each line showing the time of the reboot and the uptime from then to shutdown. Using last -x reboot shutdown to show the shutdown time, here's an illustration
Code:
shutdown system down 2.6.29.6-smp Sun Mar 7 15:35 - 03:02 (11:27)
reboot system boot 2.6.29.6-smp Sun Mar 7 09:35 (05:59)
09:35 until 15:35 is 05:59.
When the uptime exceeds 24 hours it is shown as (<days>+<hours:minutes) like this
Code:
shutdown system down 2.6.29.6-smp Sun Feb 21 12:39 - 13:20 (00:40)
reboot system boot 2.6.29.6-smp Sat Feb 20 09:39 (1+02:59)
09:39 until 12:39 the next day is 1 day 02:59.
The time in parentheses at the end of the shutdown lines is normally the time until the next shutdown.
So far so good. The incorrect output is for the last reboot and shutdown of an old wtmp file. Here's the output of last /var/log/wtmp -x reboot shutdown; last -f /var/log/wtmp.1 -x reboot shutdown
Code:
[snip]
reboot system boot 2.6.29.6-smp Fri Mar 12 07:42 (01:54)
shutdown system down 2.6.29.6-smp Fri Mar 12 01:31 - 09:37 (08:05)
wtmp begins Thu Mar 11 08:25:26 2010
[snip]
reboot system boot 2.6.29.6-smp Wed Mar 10 14:12 (15+01:42)
shutdown system down 2.6.29.6-smp Wed Mar 10 12:41 - 15:54 (15+03:13)
[snip]
The boot started at "Wed Mar 10 14:12" which had an actual uptime of 1 day 11:20 is reported as 15 days 03:13 which is the time from then until the last -f /var/log/wtmp.1 -x reboot shutdown command was issued. The time from shutdown to shutdown is similarly affected.
