  • Why is 'System' process at 100%?

    - by ripper234
    On Windows 7, the 'system' process is taking up 100% CPU (well 50% on a duel core) for a rather long time. Its CPU usage doesn't seem to drop at all. How can I diagnose this problem? What could be the cause? I don't see any other problems with the system and am using an up-to-date AVG, so I don't yet suspect a maelware.

  • Could not find DHCP daemon to get information on Belkin G Wifi Router

    - by Anirudh Goel
    I am using a Belkin G Wireless Router F5D7234, and i have a DSL connection with only a ethernet cable. So i connected the cable to the Modem port and allowed it to use Dyanmic IP, it worked successfully and an ip was assigned to it and multiple computers could connect to it and browse. But after some time the power went off and after then upon rebooting it is taking about half hour to get an IP address. Upon seeing the log i see this entry repeatedly 07/02/2010 23:22:34 DHCP Client: [WAN]Could not find DHCP daemon to get information 07/02/2010 23:22:32 DHCP Client: [WAN]Send Discover 07/02/2010 23:22:30 DHCP Client: [WAN]Send Discover 07/02/2010 23:22:28 DHCP Client: [WAN]Send Discover 07/02/2010 23:22:26 DHCP Client: [WAN]Send Discover 07/02/2010 23:22:26 DHCP Client: [WAN]Could not find DHCP daemon to get information 07/02/2010 23:22:24 DHCP Client: [WAN]Send Discover 07/02/2010 23:22:22 DHCP Client: [WAN]Send Discover 07/02/2010 23:22:20 DHCP Client: [WAN]Send Discover 07/02/2010 23:22:18 DHCP Client: [WAN]Send Discover Any idea what i can do? I tried using another belkin router of same model and make and there also i faced the same problem.

  • Logging a Daemon's Output with Upstart

    - by Alex Reisner
    I have a custom daemon that is managed by upstart on my Ubuntu server. It works perfectly except that I need to capture (log) the daemon's output. The official stanzas page says that I can use console logged to do this, but what file does it log to? I've also read that console logged is no longer a valid stanza. I'm currently using 0.3.9 (Hardy) but will upgrade to 0.6.x (Lucid) in a few months. If console logged in fact won't work with later versions, what do I use instead?

  • Ubuntu 12.04 transmission-daemon and zfsonlinux: bad file descriptor and corrupt pieces

    - by Ivailo Karamanolev
    I'm running a Ubuntu 12.04 with zfsonlinux and transmission-daemon. The issues: sporadic Bad File Descriptor and Piece #xxx is corrupt errors. After I recheck the torrent, everything seems fine. That happens only when downloading: once it's in seeding mode. This only happens after the torrent client has been running for some time. I installed zfsonlinux from the offical stable ppa (https://launchpad.net/~zfs-native/+archive/stable). I previously tried running transmission-daemon from the Ubuntu repository, but since I've switched to building the latest transmission from source with the latest libevent (all stable) - same thing. I've seen bug reports (https://trac.transmissionbt.com/ticket/4147) for that issue, but none of them seem to have a solution. How can I fix these errors, or at least understand where they come from and what I can do to rectify the issue?

  • Daemon/Software that takes changes from sql database and applies them to unix config files

    - by Dude Man
    I was wondering if there was a unix daemon available that would be capable of something like this: admin adds an IP entry to a DB; daemon finds change after wait interval and manipulates ifconfig/config files I was thinking maybe there is a plugin for cfengine that might be able to do this, but I couldn't find any. I mean this would be a fairly easy thing to script up in perl, but why re-invent the wheel if theres already something out there that is better than what my limited programming abilities can make. Lastly, if it worked on FreeBSD that'd be great.

  • Disable usage of console-kit-daemon in Ubuntu

    - by Alex Marshall
    Hello, I administrate several Ubuntu 9.04 servers, and everytime I log in, I get the Landscape utility printout with server stats, etc. I really don't need this and it slows down my logins considerably. Can somebody please tell me how to disable message of the day as well as the landscape-sysin daemon ? I started tracking my logins using top, and when a user logs in, sshd shoots right up to 100% CPU usage, and I believe that landscape and the message of the day update daemon are the primary culprits. Does anybody else have any ideas as to what could be causing my horrible login times ?

  • MySQL Daemon failed to start

    - by T. Brian Jones
    THE SETUP I'm running Linux CentOS on an Amazon EC2 instance. The MySQL data files are on an EBS Drive mounted at /data/ ( symlink - /var/lib/mysql /data/mysql ). Everything works fine in this setup. THE PROBLEM I'm trying to move everything from this EBS drive to a new drive. I umounted the /data/ drive, and mounted it at /data2/. Then I mounted the new drive at /data/ and copied everything over to it from /data2/. Everything on the system works great, except MySQL. Every time I try to start the MySQL daemon ( /etc/init.d/mysqld start ) I get a MySQL Daemon failed to start error.

  • gevent with Django as daemon

    - by jonathonmorgan
    I've been developing an app using django_socketio (a python port of the Node equivalent), which relies on gevent. It ships with a Django management command that runs gevent's pywsgi server, but that of course stops when I close my terminal window, just like Django's dev server. This is a proof of concept, and there's no expectation that it would hold up in a production environment, but I'd like to have the server at least "permanently" process HTTP requests, so I don't need to manually start the dev server in order to demo. I'm assuming I need to run this as a daemon process, but prior to this I've only used apache and mod_wsgi, so unsure of where to begin, or even how I would go about starting a daemon. I found gevent-spawn, which looks promising, but it's unclear to me how that code is executed. Basically, how would I use gevent to serve a Django app in a setting without manually starting/stopping the server?

  • Disabling the shell of user "daemon" (/bin/false)

    - by BurninLeo
    on a Linux system there are lot's of users by default: daemon, bin, sys, games, etc. According to my /etc/passwd most of these users have a shell assigned (/bin/sh) which seems some kind of insecure to me. My naive thinking would say: Only give those users a shell that may login to the server. Is my thinking wrong? If not completely wrong: Can I disable the shell for "daemon" and "www-data" without having side effects (e.g. the system wont start or the Apache PHP cannot excute system calls)? Thanks for your hints!

  • How to get OpenSSH to use ksshaskpass under KDE?

    - by Guss
    When using a GNOME desktop on Ubuntu, if I use OpenSSH client to connect to another computer (running from the gnome-terminal), I get a single graphic popup asking for my private key's pass-phrase. After that I no longer need to enter my pass-phrase as it is cached by the SSH agent. Under KDE it doesn't work like that - when I start ssh from konsole, I get a text prompt for my pass-phrase every single time, even though ssh-agent is running. If I run ssh-add from the terminal then I can enter my pass-phrase on the terminal and it will be stored by ssh-agent and I won't get any more pass-phrase prompts, while if I run ssh-add the KRunner graphical command line ("Run" dialog) then I get a graphical prompt with the same behavior. The problem is I have to remember running ssh-add every time I log in to the desktop. How can I get ssh to behave under KDE, the same as it does on GNOME - the first time the pass-phrase is needed, pop up a graphical dialog and store the pass-phrase in the agent. I've installed ksshaskpass, but that didn't change anything.

  • How to set up a (relatively) secure kiosk on Natty?

    - by Tim
    I'm trying to get my application to be the only thing a user sees when the machine is powered on - like a kiosk, but a little more secure. Ideally, what I'd like to happen is this: At machine power-on, the user sees the Ubuntu splash image, then my app. While the app is running, the user can't get back to the desktop or a text login prompt via any keyboard shortcut. This is the (relatively) secure bit. When the user exits the app, the user sees a shutdown image, then the machine powers off. In particular, I'd like to configure things so that the user never sees the Gnome desktop on startup or shutdown. At the moment, I've configured a default user to be logged on automatically, with an autostart item which starts my app, but after the Ubuntu startup screen the user sees the Gnome desktop briefly before my app is started. When the app is exited, the user is taken back to the Gnome desktop and has to shut the machine down manually. Also, because of time constraints, I can't really start over with a different window manager. Is there an easy way to configure all of this?

  • Booting Ubuntu 12.04 in Unity the Windows Theme & Icon Theme reversed back to and always locked to Ubuntu default

    - by Antonio
    I did set up last year Faience-Ocre as my Icon Theme and Adwaita Cupertino L Unity as my Windows Theme (the GTK+ thme was unchanged to Adwaita (default)). It has worked perfectly well until 3 days ago when starting my PC I saw the Ubuntu default showing up for Windows & Icon Theme. I noticed that at start-up the disk access LED is not lit up continuously as before but at moment stops reading for a few seconds (up to 15 s) then complete the disk reading process. When all was working well this LED would lit up continuously. Another thing is that GNOME applications are as well not working well as previously Nautilus and Gedit now don't use the global menu in the system bar but a local window menu. Nautilus - Nemo before the incident Nautilus - Nemo now ... I did open dconf to check the desktop settings in org-gnome-desktop-wm-preferences and everything is looking good. When I change the settings in the app Advanced Settings in the Theme folder I see the respective value changing in dconf. However, there is no change on my desktop. It looks like it's crippled and GNOME related. [Update 1]: I have the same defect as referenced @ ubuntu theme suddenly changed to default and it's not coming back! instead of my GTK theme I get a classic, Windows-95-like grayish theme ... However one of the solution mentionned: http://www.webupd8.org/2011/06/fix-ubuntu-linux-mint-theme-changing-to.html is not working at all, even for 20 s up to 60 s delay.

  • Gnome3 shell video corruption with ATI Radeon HD 4850 on 11.10 Oneiric

    - by AndyAtTheWebists
    I have a problem similar to what's been mentioned in a few other questions, namely: Ati incompatible with Gnome-shell? Gnome Shell Glitched Top Bar Ubuntu 11.10 I have read a number of other posts here and on other forums and have tried a bunch of different solutions. The Problem The problem manifests itself only in Gnome3. I have tried KDE, Unity and KFCE and all are fine. The graphics corruption is visible only on gnome panels (see images below). Everything works fine with the free ATI drivers, but they just lack power. The problem occurs with the proprietary ones from AMD/ATI. I have installed version 11.11 and 12.1 as per the instructions on wiki.cchtml.com/index.php/Ubuntu_Oneiric_Installation_Guide. I have the same exact problem in both cases. I have tried this on clean installs of Ubuntu 11.10 Oneiric Ocelot (x64 and x86) and on Linux Mint 12 (x64) with the same results. Also, it looks like after some time of not using it, the PC just freezes. Maybe an overheat? Will look into it. Things I've Tried I have tried the following fixes: Different versions of drivers from ATI including the latest - this worked for some, not for me. Installing Oneiric specific package generated from driver, as well as the default install Removed the Unity Global menu Disabled file manager handling desktop Disabled Compiz "detect refresh rate" Sync to VBlank in Compiz on and off Please help! This is the first time in 10 years that I've finally had the chance to switch my primary desktop to Linux (stopped doing .NET dev work), and this is really getting me down. This is what the problem looks like: And:

  • Custom LightDM sessions to launch an application

    - by zachtib
    I'm trying to set up Ubuntu to act as a kiosk running a custom application, and am trying to get a LightDM session built to automatically start it. Ideally, I'd like to have two sessions available from LightDM. The default would start my application fullscreened, and the other would open a minimal desktop in case any configuration (mostly connecting to a wireless network) needed to be done. I've done a lot of research over the last week on custom LightDM & Gnome sessions. I've got a custom greeter written for LightDM that can start either session, but I can't figure out how to add a specific application to the Gnome session that is ultimately started without just putting a launcher in the global startup directory, and I don't want to do that since I don't want the application starting when they open "configuration mode". Another problem I've run into on my current workaround is that the application doesn't fullscreen properly, which makes me think I'm not starting enough of a gnome session (currently it's just metacity, no panel or anything else). Edit: I found a solution. See http://www.webupd8.org/2011/11/make-applications-autostart-only-in.html

  • System State Backups using NTbackup fail with error 0x800423f4 (relating to volume shadow copy)

    - by Paul Zimmerman
    We have a Windows Server 2003 R2 running Service Pack 2. It is a domain controller (Global Catalog) and our main internal DNS server. We run a System State backup of the machine to back up Active Directory information and save the backup to a different server. This server has a single drive (C:), and we do have Shadow Copies enabled for the volume (which are completing successfully). The System State Backup is now failing with the following listed in the backup logs: Volume shadow copy creation: Attempt 1. "Event Log Writer" has reported an error 0x800423f4. This is part of System State. The backup cannot continue. Error returned while creating the volume shadow copy:800423f4 Aborting Backup. The operation did not successfully complete. When doing a vssadmin list writers, we sometimes get the following reported for the Event Log Writer (other times it says that it is in the state of "[1] Stable" with "No error"): Writer name: 'Event Log Writer' Writer Id: {eee8c692-67ed-4250-8d86-390603070d00} Writer Instance Id: {c7194e96-868a-49e5-ba99-89b61977753c} State: [8] Failed Last error: Retryable error We have tried disabling the event log service via the registry, rebooting, deleting the event log files from the drive, then re-enabling the service via the registry and rebooting, but this didn't seem to solve the issue. We also get an error message when in the event viewer when trying to open the log for the "File Replication Service" of "Unable to complete the operation on 'File Replication Service'. The security descriptor structure is invalid." I have searched the error via Google and tried a number of different things, but nothing has seemed to help. Any suggestions on what we might try to get the Event Log Writer to behave would be greatly appreciated!

  • Looking for a help desk ticketing system..

    - by Dan
    Hi guys Im looking for a good help desk ticket solution. It must perform the following actions for it to be useful. It needs to have a single point of contact via email..e.g [email protected] If we recieve a telephone(or an email outside of the system) we need to be able to create a ticket as if had been added via the single point of contact, this needs to be done with ease in order to save time. Certain people within our organisation deal with certain customers, so if the email/ custom input support call as mentioned in bullet 2 is picked up as having a relationship with that certain person in our organisation it needs to be sent to them/put in their queue for them to work on. If a person is out of office or sick any tickets sent to them must be forwarded to somebody else or put into a seperate pool of tickets that anybody can access. Perhaps have an agent that sorts through tickets in the pool and assigns them to anybody who is available, preferably the person with fewest tickets in their queue/list. Once a customer emails and the system logs it they immediately get a response with a ticket number and maybe details of who is dealing with the problem. Any correspondance in relation to a particular ticket is automatically grouped into some sort of message, and not made into a load of separate tickets. I.e system scans incoming email subjects for ticket numbers and assosciates it with exisiting tickets if that number exists. Any help is much appreciated Thanks P.S I have taken a look at OTRS but i'm not feeling it so unless someone can convince me I guess i'm after an alternative.

  • how to remove an entry from system tray?

    - by altvali
    I've searched for an answer to this one and I haven't found one yet. How do i remove a single item from Windows' System tray? I'm targeting Windows XP. Edit: This is not about preventing items from starting up. I want the program to keep running, I just need another script/program to remove the first one's entry from system tray. Second Edit: One approach that I can think of is to try to hide the intended app by modifying registry keys. On several test machines I've found some registry entries that match the System tray information at HKEY_USERS\something-that-looks-like S-1-5-21-682003330-1563985344-725345543-1003\Software\Microsoft\Windows\CurrentVersion\Explorer\TrayNotify with BalloonTip, IconStream and PastIconsStream containing systray information. The important one is IconStream. On other machines, these are found at hkey_classes_root/local/setting/software/microsoft/windows/currentversion/TrayNotify I'm quite sure there's no danger in changing those specific registries, but I don't know how to write code for that. Can anyone help me with the code and with confirming if this has the desired effect of hiding the systray icon for an active program?

  • Hourly SQL Server 2005 Slowness (Possibly caused by SYSTEM)

    - by Zorlack
    We're trying to diagnose the cause of slowness on our Database server. We're running the latest rev SQL Server 2005 on Windows 2008x64. The behavior that we're seeing is this: We see the SYSTEM process spike one of the CPUs for about 2 minutes, during this time SQL server slows down by a factor of 10. The slowness lasts until SYSTEM is done, then in an hour everything starts again. During these slowdowns disk writes don't spike, paging doesn't spike, the only noticeable precursor we see is that SYSTEM maxes out one of the sixteen (HT)CPUs. Note that this doesn't happen at the top of the hour, it just happens once an hour, and it shifts a bit depending on the length of the incident. At the moment this is causing intermittent slowdowns, but when the server is really busy it can cause Worker Thread starvation. The server is a Dual Quad Dell R710 with 96GB of RAM and RAID10 data/log disks. Has anyone experienced this kind of problem? Does anyone know where we should look?

  • System Center 2012 VMM UI is very slow

    - by Grant
    I've recently setup system center 2012 a new server 2008 r2 server which I'm using for virtual machines. Everything seems to be working fine, and the virtual machines are nice and fast. But the Virtual Machine Manager interface is always excruciatingly slow. Sometimes taking up to 15 seconds moving between screens. It's very frustrating trying to use it when a task that just involves a couple clicks ends up taking several minutes. Pages that have a lot of form fields seem to take the longest to load - such as the page to change hardware settings of a virtual machine. Is this just normal performance for VMM? If not, where can I look to find what is slowing it down. Nothing else on the system seems to suffer. I can load and use Hyper-V manager with no noticable slowness. Even programs like event viewer that are usually rather slow seem to load fairly fast. Only the system center programs seem slow. Server is a Dell R710, 2x16 core opteron 6274 processors, 96GB RAM. OS drive is 2x500GB 7.2k RPM SAS drives in RAID1 (opted for the less expensive 7.2k drives since pretty much everything is stored on the SAN). Am I just being impatient? Does anyone else use VMM 2012 and find it slow?

  • GNOME PPP doesn't connect

    - by Motorhead
    I am a new ubuntu user and connect to the internet using wi-fi broadband on my notebook. But I need to setup a dial-up connection through my phone which can keep me online while I travel. I have tried connecting to dial-up using pppconfig, wvdial and gnome-ppp. I do not know whether they use the same files for connecting but I have only been able to connect using Gnome-ppp. But the connection is intermittent and disconnects every five seconds or so. The exit code is 16 which I checked in man and got to know that the modem hangs itself up. I am connecting my phone to ubuntu as a usb modem. And as I am new I might have skipped a step or two. Please suggest a solution or an alternative to this. I have put down the Gnome-ppp log.

  • Where are gnome keyboard shortcuts stored

    - by Evan Plaice
    I usually load a new version for every release to keep my OS fresh while preserving the last version on another partition as backup. I also employ a lot of custom key mappings (IMHO, the defaults suck). I've figured out how to transfer the majority of my configuration across systems so far but I can't figure out where the custom keyboard shortcut mappings are stored. Does anybody know where gnome puts these? Are there separate user config (Ie. ~/) and system config (Ie. /etc) files?
