  • Editing Exim's Banner

    - by Tiffany Walker
    Is there a way to place EXIM smtp banner on 1 line instead of 3 lines? The banner starts with 220. I've been searching but can not find a way. under /etc/exim.conf I have #todd host's smtp_banner = "${primary_hostname} ESMTP Exim ${version_number} \ \#${compile_number} ${tod_full} \n\ We do not authorize the use of this system to transport unsolicited, \n\ and/or bulk e-mail." do i make that one line?

  • Hotfix entries in event log

    - by Marco Shaw
    Server 2008/2008 R2 I'm trying to remotely monitor these servers to watch the progress of hotfixes being installed. I was able to find this in Server 2003/2003 R2: -Log: System -Source: NtServicePack It seems the above event is written when every hotfix is installed. I can't seem to find a comparable entry in Server 2008/2008 R2 though. Is there anything similar that I can easily monitor for remotely?

  • Determine Users Accessing a Shared Folder Using PowerShell

    - by MagicAndi
    Hi, I need to determine the users/sessions accessing a shared folder on a Windows XP (SP2) machine using a PowerShell script (v 1.0). This is the information displayed using Computer Management | System Tools | Shared Folders | Sessions. Can anyone give me pointers on how to go about this? I'm guessing it will require a WMI query, but my initial search online didn't reveal what the query details will be. Thanks, MagicAndi

  • Microsoft Security Essentials Not Monitoring

    - by nateify
    When I boot into Windows Vista, Microsoft Security Essentials is set to run when the system starts. When I open the program, it says Microsoft Security Essentials isn't monitoring your computer because the program's service stopped. It tells me that it can't update definitions or enable real time protection unless I do it manually (every time I boot). Is there a way I can fix this so I always have real time protection and updating?

  • Widely-used load balancing solutions?

    - by Vimvq1987
    I asked this question http://serverfault.com/questions/124329/network-load-balancing-efficience-and-limits, and a bit disappointed that NLB was not a widely-used solution. I want to ask about widely-used solutions in the world now. Can you give me a list and a brief introduction for each? Cause of limitation of my thesis resource, I need to focus on software-only, Windows-based solution (both database level and system level are welcome). Thank you so much!

    Recently found a behaviour where my application had a connection in TCP Close_wait state till the app was restarted (after about 5 hours). But during this period the SUnreclaim space was also increasing constantly and went down on restart. The application is runnning on a rhel5 os and Im not very familiar with the memory management system. Would appreciate if someone clould tell me what extactly is the Ureclaim space and why it is increasing in sync with the close_wait. Thanks.

  • Cannot delete audit logs with sudo

    - by DazSlayer
    I am using auditctl to log all commands run on my Ubuntu system and I working on a script that parses the log into a more readable format. Since these logs tend to become very large, I want to periodically delete the logs. I found that by running sudo rm /var/log/audit/* I would get rm: cannot remove `/var/log/audit/*': No such file or directory however by running sudo su rm /var/log/audit/* The logs would be deleted without any problem. What could be the cause of this?

  • Ubuntu Newbie Needs Assistance!!

    - by Steve Greene
    New Ubuntu User Needs Help!- version 9.10 does not communicate with laptop Hello folks, Several days ago, I installed Ubuntu 9.10 onto my Acer Aspire 3100 laptop, running it alongside Widows Vista as a dual-bootable system. Creation of the Ubuntu boot CD went fine, and the installation onto my hard drive was flawless. Ubuntu opens and behaves as I would expect, except for one little problem. For reasons unknown to me, Ubuntu is not communicating with my laptop's networking hardware, and I have no internet connectivity, even when sitting directly under the wireless router at the local library (literally), which puts out a wickedly-fast signal that my Windows Vista OS auto-detects and immediately connects to. Up in the right side of the Ubuntu desktop, I click on the network icon and it does not show a wireless connection at all, even though I am only a few feet from the router. At home, where I use a dialup modem, I also see no means of getting online. My modem is an HDAUDIO Soft Data Fax Modem with Smart CP,manufactured by CXT (Conexant Systems Inc., file version 4.0.13.0, and the driver version is 7.58.0.0). I desparately wish to convert to Ubuntu. I used Mac for ten years, and then Windows for ten years. Now, after 20 years, I want to live out my days as an open-source Ubuntu fanatic. I am ready to give the old status quo the boot! I am an advanced computer user, but I am not a programmer. I seek a solution that is user-friendly for normal people, something equivalent to a driver that I can easily install or activate that will allow Ubuntu to see my hardware and get me connected. Can anyone help me over this hopefully-little glitch so that I can move on in total Ubuntu bliss? My processor is a Mobile AMD Sempron Processor 3500+ at 1.80 GHz, 1.50 GB RAM, and a 32-bit Operating System. I am running Windows Vista Home Basic, Service Pack 2. My current email is [email protected] if you have a workable solution that does not require programmer status to implement. Surely this must be a simple fix that I simply am overlooking, but being the new guy on the block, I have yet to be enlightened. Thanks for your help in coming up to speed!!

  • The Koyal Group Info Mag News¦Charged building material could make the renewable grid a reality

    - by Chyler Tilton
    What if your cell phone didn’t come with a battery? Imagine, instead, if the material from which your phone was built was a battery. The promise of strong load-bearing materials that can also work as batteries represents something of a holy grail for engineers. And in a letter published online in Nano Letters last week, a team of researchers from Vanderbilt University describes what it says is a breakthrough in turning that dream into an electrocharged reality. The researchers etched nanopores into silicon layers, which were infused with a polyethylene oxide-ionic liquid composite and coated with an atomically thin layer of carbon. In doing so, they created small but strong supercapacitor battery systems, which stored electricity in a solid electrolyte, instead of using corrosive chemical liquids found in traditional batteries. These supercapacitors could store and release about 98 percent of the energy that was used to charge them, and they held onto their charges even as they were squashed and stretched at pressures up to 44 pounds per square inch. Small pieces of them were even strong enough to hang a laptop from—a big, fat Dell, no less. Although the supercapacitors resemble small charcoal wafers, they could theoretically be molded into just about any shape, including a cell phone’s casing or the chassis of a sedan. They could also be charged—and evacuated of their charge—in less time than is the case for traditional batteries. “We’ve demonstrated, for the first time, the simple proof-of-concept that this can be done,” says Cary Pint, an assistant professor in the university’s mechanical engineering department and one of the authors of the new paper. “Now we can extend this to all kinds of different materials systems to make practical composites with materials specifically tailored to a host of different types of applications. We see this as being just the tip of a very massive iceberg.” Pint says potential applications for such materials would go well beyond “neat tech gadgets,” eventually becoming a “transformational technology” in everything from rocket ships to sedans to home building materials. “These types of systems could range in size from electric powered aircraft all the way down to little tiny flying robots, where adding an extra on-board battery inhibits the potential capability of the system,” Pint says. And they could help the world shift to the intermittencies of renewable energy power grids, where powerful batteries are needed to help keep the lights on when the sun is down or when the wind is not blowing. “Using the materials that make up a home as the native platform for energy storage to complement intermittent resources could also open the door to improve the prospects for solar energy on the U.S. grid,” Pint says. “I personally believe that these types of multifunctional materials are critical to a sustainable electric grid system that integrates solar energy as a key power source.”

  • Impossible to create/format install window 7 on unpartioned HD

    - by fra pet
    Hi guys i am getting nut reinstalling windows 7 on one of those Acer aspire all-in-one... The original OS(windows professional x64) was not starting, after the initial screen the bios was prompted. So step 1: i tried to access the system partition and reinstall everything but could not get at the point step 2: i set the bios to native ide and i tried to insert my original copy of windows professional and do a clean installation, but it does not allow me to format/create other partion form the installation mask step 3: my BAD, i tried to install ubuntu and i clean the whole hard drive, i was getting an error at some point during installation so i decided to get back to windows step 4: Windows 7 again, at the disk screen of the windows installation i entered into the prompt and played around with DISKPART... -i listed the disk and the HD was disk 0. -i selected disk 0. -i CLEAN disk 0 successfully. -i tried to create a CREATE PARTITION PRIMARY but gave an error cache corrupt and disk not up-to-date (after i try to create a partiton in disk 0 it disappear when i try LIST DISK and i have to restart before he can list DISK 0 again, RESCAN did not worked). -tried CLEAN ALL(2 hours) and succeeded. -try again to create primary partition and failed, same errors -try to install my old copy of windows xP pro and it seems to work, it create a partition, format(only quick worked, slow mode was at 0% after 1 hour so i stop), it start installing and around 90% installation said it could not copy a file and he stop -back on windows 7 again, it says that the hard drive has 490+gb unpartitioned but won't create a partition and format. -i tried again DISKPART as i though i messed up with the MBR when i installed ubuntu, so i did all of the instruction below http://www.sevenforums.com/tutorials/20864-mbr-restore-windows-7-master-boot-record.html http://support.microsoft.com/kb/927392 the errors were: on bootsect: the systne partiton was not found, Data error cyclic redundancy check on bootrec /FixMbr: A device attached to the system is not functioning but did not worked, and still can not partiton/format/install on a blank HD i tried some bootable clean disk tool and start infinite loop on the same errors the bios setting are: sata: native ide. if i put AHCL(or something like that does not load the HD and the DVD). quick start/quite start: disabled. Are there any other option or tools i can try before i try change the HD(That is my last option)? Thanks to everyone.

  • Capturing wireless traffic (using Wireshark).

    - by Daisetsu
    When I run wireshark on a wired network it works fine and reports all of the packets. When I run it on a wireless network though I only see my own traffic. The wireless card I have is supposed to support packet capture and go into premiscous mode, but I don't see any other system traffic. What is wrong?

  • Windows 7 fails to install on KVM with qemu

    - by kief_morris
    I'm trying to install Windows 7 on a virtual machine on my 64 bit Ubuntu Karmic box. I get to the point of selecting my language settings and clicking 'install now', but a short while later I get a blue screen of death. I've tried a few variations, including using the 32 bit (fails very quickly). The virt-install command I've tried includes this: sudo virt-install --connect qemu:///system -n ksm-win7 -r 2048 \ --disk path=/home/kief/VM-Images/ksm-win7.qcow2,size=50 \ -c /var/Software/Windows7/Full/64bit/SW_DVD5_SA_Win_Ent_7_64BIT_English_Full_MLF_X15-70749.ISO \ --vnc --os-type windows --os-variant vista --hvm The limited info I could find suggested that 'vista' should work as the --os-variant, I haven't found any values specific to windows 7. Here's my blue screen: I've found very little by Googling, so I'm guessing this isn't a case of KVM simply not supporting Windows 7. Thanks for any help. Update: I have been able to successfully create a Windows 7 VM using the graphical "Virtual Machine Manager" app, although I don't really understand the cause of the problem with the VM created with virt-install. Comparing the configuration files under /etc/libvirt/qemu provides some clues, although I don't know enough to interpret them properly. The interesting differences in the two VM configurations are: --- win7-virt-install.xml +++ win7-vmm.xml -<domain type='qemu'> +<domain type='kvm'> @@ -21 +21 @@ - <emulator>/usr/bin/qemu-system-x86_64</emulator> + <emulator>/usr/bin/kvm</emulator> @@ -23 +23 @@ - <source file='/home/kief/VM-Images/ksm-win7.qcow2'/> + <source file='/var/lib/libvirt/images/ksm-win7x64.img'/> I'm not sure if this means the working VM is not using qemu at all, or if there is some other difference in the way it's used with kvm. Update2: So I've answered my own question (mostly) below. A KVM VM needs to use KVM's own CPU emulation rather than qemu's in order for me to get Windows 7 installed. I'm not sure whether there is something that can be done to get it working on a qemu-emulation CPU, or whether a newer version will support it. But at least it is possible to get it running on a KVM VM.

  • How to include multiple XML files in a single XML file for deserialization by XmlSerializer in .NET

    - by harrydev
    Hi, is it possible to use the XmlSerializer in .NET to load an XML file which includes other XML files? And how? This, in order to share XML state easily in two "parent" XML files, e.g. AB and BC in below. Example: using System; using System.IO; using System.Xml.Serialization; namespace XmlSerializerMultipleFilesTest { [Serializable] public class A { public int Value { get; set; } } [Serializable] public class B { public double Value { get; set; } } [Serializable] public class C { public string Value { get; set; } } [Serializable] public class AB { public A A { get; set; } public B B { get; set; } } [Serializable] public class BC { public B B { get; set; } public C C { get; set; } } class Program { public static void Serialize<T>(T data, string filePath) { using (var writer = new StreamWriter(filePath)) { var xmlSerializer = new XmlSerializer(typeof(T)); xmlSerializer.Serialize(writer, data); } } public static T Deserialize<T>(string filePath) { using (var reader = new StreamReader(filePath)) { var xmlSerializer = new XmlSerializer(typeof(T)); return (T)xmlSerializer.Deserialize(reader); } } static void Main(string[] args) { const string fileNameA = @"A.xml"; const string fileNameB = @"B.xml"; const string fileNameC = @"C.xml"; const string fileNameAB = @"AB.xml"; const string fileNameBC = @"BC.xml"; var a = new A(){ Value = 42 }; var b = new B(){ Value = Math.PI }; var c = new C(){ Value = "Something rotten" }; Serialize(a, fileNameA); Serialize(b, fileNameB); Serialize(c, fileNameC); // How can AB and BC be deserialized from single // files which include two of the A, B or C files. // Using ideally something like: var ab = Deserialize<AB>(fileNameAB); var bc = Deserialize<BC>(fileNameBC); // That is, so that A, B, C xml file // contents are shared across these two } } } Thus, the A, B, C files contain the following: A.xml: <?xml version="1.0" encoding="utf-8"?> <A xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Value>42</Value> </A> B.xml: <?xml version="1.0" encoding="utf-8"?> <B xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Value>3.1415926535897931</Value> </B> C.xml: <?xml version="1.0" encoding="utf-8"?> <C xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Value>Something rotten</Value> </C> And then the "parent" XML files would contain a XML include file of some sort (I have not been able to find anything like this), such as: AB.xml: <?xml version="1.0" encoding="utf-8"?> <AB xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <A include="A.xml"/> <B include="B.xml"/> </AB> BC.xml: <?xml version="1.0" encoding="utf-8"?> <BC xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <B include="B.xml"/> <C include="C.xml"/> </BC> Of course, I guess this can be solved by implementing IXmlSerializer for AB and BC, but I was hoping there was an easier solution or a generic solution with which classes themselves only need the [Serializable] attribute and nothing else. That is, the split into multiple files is XML only and handled by XmlSerializer itself or a custom generic serializer on top of this. I know this should be somewhat possible with app.config (as in http://stackoverflow.com/questions/480538/use-xml-includes-or-config-references-in-app-config-to-include-other-config-files), but I would prefer a solution based on XmlSerializer. Thanks.

  • Best practice for setting up SQL server on a Virtual Machine

    - by CrazyCoderz
    This is my first attempt at virtualizing SQL server on VMWare and I want to make sure I am doing things correctly. Should I have SQL server installed on the C: drive / same partition as the OS, Then add a virtual disk for the Data files, say 300GB, and then another virtual disk for the log files say 100GB? Or should I add 2 300GB vdisks, for the data files mirror them in the operating system, and then add a non mirrored vdisk of 100GB for LogFiles??
