Is there a commandline utility for rebooting the OS without rebooting the computer's hardware? In X, this would be similar to logging out and logging back in. I just need to be able to do it without a graphical display, keyboard, or mouse.
View 3 RepliesI'm using Ubuntu 9.10, and a usb webcam that is shown as 'Bus 001 Device 005: ID 0ac8:3450 Z-Star Microelectronics Corp.' by lsusb.
The problem is that on connecting the cam, it just works with the first program I start (skype, tokbox, messenger), and if I disconnect it or switch to another program, it stops to work and I have to restart my computer to make it work again.
Is there some good solution to reset the camera without rebooting to make it work again?

View 3 Replies View RelatedI just installed a CentOS 5.4 x 64 on a customer's server last Saturday. I use lpr/lpd to print through this server to our network printers.
yum install cups-lpd
Edit /etc/xinetd.d/cups-lpd: disable = no
I did several restarts on /etc/rc.d/init.d/cups. I even did a "kill -SIGHUP 0" and a "kill -SIGHUP pid_xinetd". No joy. I finally gave up and rebooted: joy. Shades of Windows.
What did I miss? How do I start cup-lpd after yum without rebooting.
I have two dual boot systems, each running Fedora 11 and a version of Windows.When I boot into Windows after running Fedora on either, the Windows time is wrong and I have to reset it. But, if I reboot from Windows into Windows, the Windows time is right . I think this results from different ways Fedora and Linux keepi track of time and what they do to the real time hardware clock.Could someone explain exactly what is going wrong and how I can resolve the problem?

View 11 Replies View RelatedAbout 2 weeks ago i installed ubuntu 10.10 and downloaded fresh network drivers. I ran autorun.sh, the module was compiled and installed, i could see it with lsmod. But after rebooting the old module appeared again, but no file for him were in modules directory because autorun.sh removed old module file. Some time passed and I figured out that it is initrd who is guilty. I couldn't check it because i already deleted ubuntu and installed Fedora 14 Beta. Today i tried to repeat my steps and installed new network module on Fedora. But when i rebooted and started again i was surprised - new module works instead my old one. Everything is fine So, my question, does Fedora use initrd? I saw some files in /boot that which are initrd files (as i think). Or may be not every fedora system uses initrd or something else?
View 7 Replies View RelatedMy laptop (as many others) has a hardware switch which turns wireless/bluetooth disabled. If after booting up the system I switch on this key, the wireless would still remain disabled and I need to reboot the system to be able to connect to any network.
I have tried
Code:
rfkill unblock all
ifconfig wlan0 up
Is there any way to activate wireless without rebooting the system?
We have some Ubuntu x64 8.04 servers that sometimes get stuck when rebooting. The only thing we see on the screen is "Loading, please wait" and some stuff below. I am attaching a picture of the monitor. We have this specific server set to reboot constantly while we try to figure out the issue however we don't know where to start, can we look at logs at this point (probably not since the hard drives aren't mounted yet), can we add debug info?

View 1 Replies View RelatedI've noticed that there's no Network Manager icon on my notification area after rebooting, no matter how many times I delete my GNOME panel configuration and restore the defaults. However, after rebooting, if I restart the D-Bus service (and thus my whole desktop), the NM icon does appear - even though NetworkManager is not running. I've already tried reinstalling gnome-panel, network-manager, and dbus, which hasn't changed anything.
How can I make the NM icon appear every time I log in?
I'm having problems using a swap file to increase swap space in Linux. I followed the instructions for creating a swap file, as shown here:
[URL]
It works, and I increased my swap space. But when I reboot, I'm back to the original amount of swap space I had before. The swap file I created is still there, but it's not being used as swap space. I tried remounting the swap file but it doesn't work.
Also, it seems there isn't an fstab entry created for the swap file. Strange, huh? I don't think it made a difference but I manually copied the UUID for the swap file and made an entry in fstab.
I may be wrong, but from what I can tell the UUID of the swap file keeps changing every time I reboot.
So basically every time I reboot I have to repeat the instructions shown above to get more swap space.
Since I upgraded to 10.10 my system keeps rebooting spontaniously.... Haven't been able to find anything wrong with the system, other than the reboots.
View 6 Replies View RelatedHere I was, humming happily along on my Ubuntu 10.10 machine, when thanks to a stupid Windows proprietary task that I NEEDED to perform, I rebooted in Windows later this morning. When I was done with the task, I tried to reboot again back in Ubuntu, but lo & behold, it wouldn't start. I tried several times, I tried recovery mode, I tried previous versions, and NADA! It's as if the kernel only existed in name only. So now I don't know what to do, because I cannot access my Ubuntu files from Windows (which luckily still works), plus I cannot abide the idea of having to give up on Ubuntu for good and going back to Windows! I'm willing to reinstall the whole thing again, so I've downloaded a new .iso image to create a new install CD, but I cannot seem to successfully create the new CD image either. I'm tempted to download Wubi, but I'm not sure if that's a permanent solution either.
View 9 Replies View RelatedI"ve started using Ubuntu 11.04 with my Intel iMac. Today I was playing EDuke32 on Ubuntu then the game got freezed, so I tried Ctrl+Alt+F1 and it worked. I just logged in the console and typed;
sudo reboot
This actually didn't work, so;
/usr/bin/sudo /sbin/reboot
This worked.
After rebooting, I tried log in with the GUI login screen. However I just cannot login. After I input my password and press enter, login screen goes black out and comes back to the login screen. I also tried to log in from console (Ctrl+Alt+F1), and it worked. I can log in.
If i install new hardware using a vmguest or physical system How can I detect it.
disk
nic
memory
etc.
In AIX we just run cfgmgr -v. Is there a similar command in Red Hat?I am guessing a reboot will pick it up if the device drivers are common enough and in the kernel already. I want to know how to do this dynamically with the system on-line if possible.
Can I add memory to the Linux box without rebooting the system? I think Linux check the hardware at booting time. But if I need to add more memory to the server while I do not want to stop the service. Is there some method to make Linux use the new added memories?

View 1 Replies View RelatedI am running a 5 node 11g RAC cluster with cluster ready services. The hardware is HP BL460g6 with virtual connect modules on each chassis. The OS is RHEL5.5, 2 Qlogic 4G fibre cards, 2 Broadcom NICs bonded, and the backend disk is all Hitachi 15k. The issue that I'm seeing is periodically each day there are spikes in I/O waits for disk writes, and sometimes that will cause a node or 2 to reboot when CRS can't communicate with the other nodes. Both nodes that have been evicted, are on the same chassis. What I've checked is, the backend storage is not seeing ANY high utilization, in fact it's running at less than 10% all the time. The network is 10G, and is not showing errors on the switch, or on the blades themselves. The redo logs have a 10M buffer cache, and are running on ASM disk. What other information would be beneficial to check? I am seeing nothing in the logs as to any errors, or waits for disk writes. I believe it's a software issue, but am lost as to how to prove it. These aren't the only nodes experiencing periodic high I/O waits, and it happens at the exact same time on all systems, whether they run ASM or are part of a cluster.
View 1 Replies View RelatedI am running Debian Squeeze on an Intel DH55TC motherboard. When I issue a shutdown command
shutdown -h now
The system goes shutting down. Eveything looks fine, and the main console shows all process being stopped. In the end it says "System will now halt". Then a few seconds later, it restarts. It is unclear what is causing this, because nothing is written to the screen. It just goes blank and starts rebooting. Looking afterwards in syslog doesn't show anything also.
