I need to know how to send message (or execute script ) when the linux machine shutdown or reboot stage.
Actually I want to start a backup linux machine when main server shutdown or Reboot.
simply, how we can run script while init 0 OR init 6 command
I'm trying to reboot the server (shutdown -r now).But it seems like nothing happened.
When I try "shutdown -c", the system prompts "shutdown: cannot find pid of running shutdown."
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.
After a couple of days, some commands related to the disk (df) or files (ls) or killing process (kill -9) doesn't respond. Even I can't reboot or shutdown my server. After an hard reboot, some files are not here anymore or the log files are not filled anymore until I restart.My disk are behind the RAID controller i6 and are configure in RAID 1. The disks are two HP SCSI 72,8GB 10k RPM.Maybe I am totally wrong to check the disk access side, so I am open to other explanation.I can also add that my CPU is running under 1% et my RAM under 10%.

View 3 Replies View RelatedI am running Debian Squeeze with the following basic services running:DNS
DHCP
Samba
Squid
The server is setup with three NICs: eth0 (WAN1), eth1 (WAN2), and eth2 (LAN).The server addresses clients with an IP range of 10.0.30.1 - 10.0.30.254. Some clients will be set with reservations so they fall into the 10.0.40.1 - 254 range.
What I want to do is have any outgoing external traffic coming from the first range (10.0.30.0) to use WAN link 1, and any outgoing external traffic coming from the second range (10.0.40.0) to use WAN link 2.
I have sort of got something working. I have created a bare minimum transparent squid3 setup on port 3128, and set the iptables as follows:
Code:
iptables -t nat -A PREROUTING -i eth2 -p tcp -m tcp --dport 80 -j DNAT --to-destination 10.0.0.1:3128
iptables -t nat -A PREROUTING -i eth0 -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 3128
iptables -t nat -A PREROUTING -i eth1 -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 3128
I can get internet access, however obviously it only goes through one WAN link. It also seems slower than it should be. I experimented with tcp_outgoing_address, but seemed to not be my friend.
i have a small issue, to make our network more secure, i now require outgoing email to require authentication. Now the problem..i have a automated mailer that does not have the option to authenticate. is there a way to allow a certain email address or the local network to send out without authentication? If i cannot do this for a single email user to allow them through with authentication, how would i remove the authentication paramaters in the postfix smtp..

View 2 Replies View RelatedI want to do a shutdown -rF 3:00 to reboot my RHEL server at 3am tomorrow and force an e2fsck on each volume. But I want the e2fsck to run with the -y switch so it automatically answers yes so it will fix any problems it find automatically.
I can't find anywhere where it says if it will do this or not. does anyone know or have proof? Or is there a better way to do what I'm trying to accomplish?
Should I be using one or the other for different things?

View 1 Replies View RelatedI have recently upgraded to the 10.04 Alpha and have been unable to reboot or shutdown. I know it's just an alpha and therefore problems are bound to exist, so I tried reinstalling from a live cd of Alpha 3. But I am still unable to reboot or shutdown.To clarify what happens, I click on shutdown or reboot, the pop-up appears, I click on the shutdown/reboot button and it seems to complete it. It says that processes have been killed and something has exited with 255. But my computer is still on. I am guessing that Ubuntu is shutting down, it's just not actually shutting my computer down or restarting it.
View 5 Replies View RelatedI have a remote server (Xubuntu 10.04) which suffered an electricity brownout yesterday. The server itself is backed with an ups, but it is connected to a external firewire disk, which is not, and this disk malfunctioned as a result of the brownout.
The problem: Now, any process trying to access the external disk freezes and ends up in eternal D state in the process list, including ls and umount. Even trying to ls a directory which contains a symbolic link to a file in that drive just causes ls to freeze. These processes cannot be killed even with SIGKILL, so I proceeded to reboot but...
None of the reboot commands work. Instead they just get added to the ever increasing list of D state processes. I tried (sudo) shutdown -r now, reboot -f now and finally plain shutdown -h now. Is there anything else to try other than ask somebody to actually go to the server and pull the plug (which is not at all trivial)? Some way to tell kernel not to worry about messing stuff up, and just reboot?
we've just bought 30 newest nettops ACER Aspire R3700 with ION 2. I've tried ubuntu, kubuntu, xubuntu. Everything works as expected, but... the first one freezes when trying to reboot, shutdown or enter sleep mode. Checked on several hardware units. The desktop just freezes and nothing happens (ubuntu 10.10, both x32 and amd64). Also no one installs the wi-fi drivers, only ethernet

Is there a shutdown log? I've looked in /var/log/messages but there's nothing relevant there.
From a 11.04 Ubuntu, I installed the meta-package xfce4 (*). Now, in the xfce4 session, "suspend" and "logout" (from the xfce4-panel button) works, but "shutdowmn" and "reboot" not, they only lead to GDM. (the shutdowm option there works.)
I tried to solve that by installing the meta-package "xubuntu-desktop" (maybe there are some necessary settings included?), and in fact, the login-screen changed (it's still GDM, I suppose) and there is now a "xubuntu" session, but in that, the probem is just the same: shutdown only leads to the login screen.
In Gnome Classic or Unity, shutdowmn works as it shoulds, so it's not a general problem with my computer.
In Detail, in forst tried to install xfce4 with ubuntu-software-center, but although it seemed to succeed, there was no xfce session. In Synaptic, installing the xfce3 metapackage worked. In fact, software-center seemed to have overlooked some dependencies...
I am facing the issue that the PC not capable to shutdown or reboot; In order to debug that, htop tells me the running processes but all seems normal, I killed few but still cold reset is needed.There is certainly a problem somewhere. the best would be to know which process are weirdly hanging. It could make this testing debian bit better to know which package has these issues.

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 ?

View 1 Replies View RelatedI hoping someone can point me in a direction. I installed F13 KDE from the live cd and now when I Shutdown or Reboot, it takes 2 minutes and 8 seconds for the machine to power off. Yes, I timed it.Happens everytime like that. Even when booting from both "mainstream" live cd and the KDE spin live cd. When I hit the Shutdown or Reboot, it goes through the daemons/services shutdown the flashes up the Halting System or Please wait while the system reboots messages (respectivley), turns off the LCD and then just... sits with the power light on and hard drive activity light on. I should mention this is on a Toshiba Laptop about 2 years old now. Intel Chipsets. (Satellite Pro S300M-S2142 if anyone is really curious). The hard drive light stays on for about 1:03 minutes and then it turns off, at 2:08 minutes - the Power light finally turns off and the thing finally shuts down or reboots. If this sounds familiar, it's because it is and I've posted about it with F12 and it's still there with F13. Running kernel-2.6.33.3-85.fc13.x86_64

I know I can use a Terminal to shutdown or reboot but a simpler solution would be nice. I expect there are methods to fix most of what I don't like about Gnome 3 but I haven't found them yet. Is there a central place for the solutions needed to deminimalize Gnome 3? I really prefer one click control.

View 1 Replies View RelatedA couple of little niggles seen with KDE4.6. On 32bit install, (openSUSE11.3 was clean install)
-- reboot and shut down do nothing but hibernate and sleep are ok, can only powerdown with su privileges,
-- order of applications in plasma bar change after reboot.
On 64bit install, (openSUSE11.3 was update of openSUSE11.2)
-- slow poweroff overcome with new user profile, (no longer a problem with latest update)
-- inconsistent mouse curser theme, over desktop theme is Oxygen White, over application windows its DMZ
(resolved mouse cursor theme issue on 64bit install.
-- /etc/sysconfig, parameter X_MOUSE_CURSOR="DMZ"
-- and
-- /usr/share/icons/default was a link to DMZ
-- /usr/share/icons/default.kde4 was a link to oxygen
-- changed so that both were linked to DMZ
-- mouse cursor now consistent within windows and across desktop.
On one of my computers that I upgraded from 11.3 to 11.4 with a SSD HDD, it no longer umounts any disks on reboot or shutdown, there are no errors shown, it goes from sending TERM and KILL to rebooting.here is my fstab:
