  • How do I use the awesome window manager?

    - by Jason Baker
    I've installed awesome on my Ubuntu laptop, and I like it. But I feel kind of lost. I don't know any keyboard shortcuts and the man pages aren't really any help (for instance, what does Mod4 mean?). Is there any kind of brief introduction to awesome I can read?

  • change from bash shell prompt to regular shell prompt on centos

    - by user881480
    my centos environment has just become bash shell prompt: -bash-3.2# how do I change it back to the usual # prompt? what places should I check for possibly modifications? Update: I was not clear in my question: the prompt used to be just a single # and supports more syntax(a different shell script than bash 3.2 perhaps)? I would like to switch back to that. for example, ll is not longer supported in this bash shell

  • How to compact a registry hive?

    - by SLaks
    I'm using a (non-administrator) roaming profile, with a size limit of 4MB. As you can imagine, it is extremely difficult to stay within that size limit. I've noticed that NTUser.dat, which holds my HKEY_CURRENT_USER hive, is 2560KB, single-handedly using more than half of that limit. Is there any way to shrink the hive without administrator privileges? I don't mind losing any settings or preferences stored in it.

  • How do I limit the CPU share of TrustedInstaller.exe on a Vista system

    - by Dan Neely
    I'm trying to fix a few low end single core desktops running Vista. In normal use they're fast enough not to be a problem. The issue is that because these machines are only on when being used, primarily for school work, windowsupdate begins installing patches it launches TrustedInstaller which in turn hogs 100% of the CPU and renders the machines all but unusable for however long it takes to patch them.

  • Repair OS From Within VMWare

    - by Zurahn
    I've got a Debian installation in an installation of ESXi that won't boot due to the deletion of a few system files that need to be restored. It would be preferable to at least access the files on the instance, if a repair is impossible. To complicate matters, there isn't enough room on the drive to upload a full distribution to boot from with VMWare disk utility. Any ideas on how to accomplish this?

  • DNS down in Anonymous attack

    - by Tal Weiss
    As I'm writing this our company website and the web-service we developed are down in the big GoDaddy outage resulting from an Anonymous attack (or so says Twitter). We used GoDaddy as our registrar and we use it for DNS for some domains. Tomorrow is a new day - what can we do to mitigate such outages? Simply moving to, say, Route 53 for DNS might not be enough. Is there any way to remove this single point of failure?

  • Set up DNS or F5 VIP to send traffic to a specific port

    - by Sam
    I have a clustered SQL instance set up at SERVER01\dev08 It's assigned to a static port of 1466. Can I set up something which will let users connect to SERVER01 and hit that port? If this is possible, what problems might it create (all traffic coming to this name hitting only one port)? It seems that DNS has nothing to do with ports - nor does the F5 big IP.

  • RAID options for a LAMP web server

    - by jetboy
    I'm due to set up a LAMP web server with four drives and a RAID controller to act as a web server. The drives are 146Gb SAS, and the machine has two quad core processors and 16Gb RAM. There will be very few write operations to the MySQL database, and I'll be using as much caching as possible to reduce disk I/O. Question is: Would I be better off splitting the drives into two RAID 1 arrays, splitting up sequential and random disk I/O, or would I get better overall performance putting them all in a single RAID 1+0 array?

  • Display tracert on Google or Bing Maps

    - by WebDevHobo
    Is there a program of perhaps website that can display a list of ip-adresses on Google or Bing maps? For instance, if I do tracert -d www.youtube.com, I'll get a bunch of IP-addresses, displaying the path my request travelled. I'd think it funny to see this on a map, but I find it hard to enter all these IP-addresses manually. Does anybody know a program that can do this?

  • Command line tool for MediaWiki?

    - by Magnus
    Is there a command line tool that would allow me to script creation of accounts on a MediaWiki instance? The UI for creating an account is painful, and very time consuming when tasked with creating 10+ accounts at a time. Unfortunately I can't get ImportUsers to work due to the very old version of MediaWiki we use (and upgrading is unfortunately not possible at this time).

  • Power states in Windows

    - by Kurt
    Does anybody know or have a link to documentation on how the Power Manager of Windows, determines to go to the ACPI power states S1-S4? Are there any settings that can be configured? I know that by default states S1-S3 are disabled in Vista and later (they can be enabled by a group policy). Can Windows cycle through these states while for instance an application is actively running?

  • HT Link Sync Error after Ubuntu 10.04 LTS Installation

    - by marklab
    Update 1 I just assembled an exact replica of this server, and successfully installed Ubuntu 10.04 LTS in a RAID10 configuration. The success was confirmed by a login to the initial account. There must be a hardware component that is faulty. Since the error mentions HT, which I believe to be Hyper Threading, I will start with the CPUs. Please indicate if this error is more strongly associated with any other piece of hardware. Or make a recommendation of another approach that would be good for this issue. Issue I was attempting to install Ubuntu 10.04 LTS on this system with the board RAID10 configured. However, the installation failed at the partitioning stage by rebooting the system. Upon reboot, there is an error report after POST listing the following: Node0: NB WatchDog Timer Error Node1: HT Link Sync Error Node2: HT Link Sync Error ... Node7: HT Link Sync Error Press F1 to continue/resume. After pressing F1 the system will boot from the Ubuntu 10.04 LTS installation disc. However, it will fail at the same stage, and go through the same process from there. Hardware CPU: AMD OPTERON X12 6172 G34 2.1G 18MB Motherboard: Supermicro H8QG6-F HDD: WD Caviar Green 2TB 5.4K RPM Troubleshooting I disabled RAID10 on the system, and installed the Ubuntu on a single drive. It installed successfully. I then went back to a RAID10 setup and attempted to install on the system again, and was able to make it through the partitioning stage. However, upon reboot, the system reported: Error: file not found, and then booted me into the Grub Rescue console. I feel I have aggravated the problem at this point because when I attempted to install from the boot disc again, the system reboots upon hitting enter to even start the installation process. It does the same thing when trying to boot from an Ubuntu 11 disc. I have not been able to find any information on this HT Link Sync Error, which I feel may have started the problems I am experiencing now with the installation of the OS. I am also aware that Ubuntu is said not to be supported by the motherboard according to Supermicro's site. However, since I was able to install it successfully on a single drive, I do not believe it is incompatible. I would like to know a reason for why it's failing to install on/off.

  • centos iptables, restrict tcp port to specific ips

    - by user788171
    I would like to modify the iptables on my CentOS 5.8 server so that only specific ips can connect to the machine on a specific port. Currently, I have the following in my iptables file: -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 5000 -j ACCEPT How would I modify that line if I wanted to allow access for only ips 1.1.1.1 and 1.1.1.2 for instance? (they might not necessarily be sequential ips when I do this for reals).

  • How does the linux update manager work?

    - by Mr.Student
    I want to know how the update manager for linux works. For instance, how does my linux distro check to see if there are any available updates for download and which servers to download these updates? If I am dealing with 3rd party software not apart of the main distro, how do those programs interact with my update manager to notify me that those programs have available updates? Lastly what would be some good literature on the subject?

  • Daisy-chaining network switches with multiple cables

    - by user72153
    This might just be the dumbest question you'll ever read, but I digress. Say I have two 100Mbps Ethernet switches with 2 computers on each, connected together by a single cable. This way, the two PCs on each switch share the 100Mbps bandwidth with the others. If I added another cable between the 2 switches, would there be 200Mbps throughput available between the switches? Or am I completely off my rocker? Thanks for the help.

  • pop3 IIS 6 , allow remote connections

    - by Que
    I'm using a EC2 windows 2003 instance. I managed to install pop3 and i can connect to it locally (using outlook express with the remote desktop) and the server address is the machine name. I also added MX record on the DNS (mail.mydomain.com) but still i can't connect to the pop3 server remotely using either mail.mydomain.com or even the server IP.

  • Focus issues in OSX Spaces

    - by AK
    Spaces rarely returns focus to my last used window. Haven't been able to peg universally reproducible steps, but spend any time switching among spaces and windows and you'll come across this. It often happens with finder windows. I'm thinking this is because osx treats Finder as a single app, so bringing finder forward in one space brings it forward in all spaces. Extremely annoying! Anyone have a fix for this?

  • Should I move to an Azure database?

    - by Mike Flynn
    I am currently using a database from an installed instance on my web server in a VM on Azure. I was thinking about moving it to an actual Azure Database so I could load balance the web server. Does the Azure database work the same way as a straight install? Will it cost more or the same since I am just moving to a new server? Basically looking for advantages and disadvantages. I am familiar with SQL Server Management Studio.

  • Can I run more than 4 virtual machines using Hyper-V Windows Server 2008 R2 Enterprise Edition as th

    - by James Holland
    I understand that a single Windows Server 2008 R2 Enterprise Edition license includes 4 free guest virtual machines using Hyper-V. Suppose I do that, and have 4 VMs running, but then want to expand. If I separately purchase additional Windows licenses, or I consolidate a machine with an existing license, can I spin up a 5th, 6th virtual machine (presuming there are enough CPU/RAM resources on the host)? Or does the host OS limit the number of virtual machines allowed?

  • How do you get the IP addresses of KVM guests that are using a Bridge Network Device from the KVM host

    - by slm
    Does anyone know of a way using KVM to find out the IP addresses of KVM guests that are using a bridge interface (br0) through the KVM host? Currently I have br0 setup with a single NIC (eth0) included. The KVM host is a system running CentOS 5.6 in case that matters. The guests are also running CentOS 5.6. BTW, the guests do not just show up in the KVM host's arp table, I'm looking for better solutions and/or leads.
