• Use msbuild community tasks without installing

  - by mickyjtwin

  In our developer environment, no users have administration rights. As such, it's not possible to install MSBuild.CommunityTasks without getting admin to do so. What I'm wondering is similar to NAnt, i.e. is it possible to include the files in your solution directory, and just reference it from there? This way, will not matter if the person has it installed, when they checkout latest code, the msbuild community files will come with, and solution will build. \SolutionDir\{solution}.sln \SolutionDir\Project\{files} \SolutionDir\MSBuild.Community\files

• TextMate - must have Plugins(web devel)

  - by dscher

  Just curious what experienced Textmate users can't live without in the program. I just ran the trial and bought the program so I'm trying to get a sense of how others might setup their development environment for web development. Also, based on the fact that I just bought the program, I am going to guess that TM2 will come out next week. Yes, that's right, next week. Unfortunately, because of my luck, it will not be a free upgrade...upgrades will cost more.

• Xencenter guest will not boot

  - by Georgi

  I have xen server free edition. Today one of the guest VM was very loaded and I decided to reboot it. Now it can not start. It is with Ubuntu 10.04 Server. The machine is shown as running in xsconsole and in windows Xen control center. It shows 100 % CPU and 100 % RAM usage. The console shows nothing (it doesn't show boot process). And the worst is that I have no backup. Is there any advice how to see what is going on. I exported it to file and now I am trying it to import it into another server, because I can't reboot the physical server it runs on. Can this save me (the reboot of the server) Thank you

• How to avoid Memory "Hard Fault/sec"

  - by Flavio Oliveira

  i've a problem on my windows 2008 server x64, and i cannot understand how can i solve it. i'm looking to Resource Monitor and see about 100 to 200 hard faults/sec. and generally the machine is slow. As i've readed a bit it is caused by a "memory Page" that is no longer available on physical memory and causes a io operations (disk) and it is a problem. The current hardware is a intel core2duo E8400 (3.0GHz) with 6GB RAM on a Windows Server Web 64-bit. Actually the machine have about 2GB Ram used what having 4Gb available to use, Why is the machine requires that high level of Disk operations? what can i do to increase the performance? Im experiencing a memory issues? what should be my starting point?

• Windows - put HDD stand-by and sleep mode

  - by iulianchira

  How can I put a hard disk drive in stand-by or sleep mode in Windows, in a programmatic manner. Does the Windows API or any .Net libraries provide any functions to achieve this? (I am aware that I should probably not interfere with Windows's power management mechanism, but this is not something I intend to use in a production environment, it is a proof of concept for some algorithms).

• Does Ubuntu 12.04.1 come with everything I need for using virtual servers and are the tools efficient?

  - by orokusaki

  I noticed that Ubuntu 12.04.1 comes with Xen, OpenStack, KVM and other virtualization-related tools. I have used VMWare in the past. If I was to use Xen for visualization, would I see considerable performance lost, since Xen is run on the host OS? Is it even run on the host OS, or is it like VMWare where it's installed below any Linux OS on the machine (embedded, I guess is the word)? Do you have any recommendations on what sort of set up to use with these built-in tools? I have 2 physical servers, side-by-side. Each will need a VM used for Postgres and a VM used as an app server. One will be a failover for the other.

• How to clear stuck locked maildrop pop3 process

  - by Joshua

  I am using cyrus for imap and pop One of my users is getting the following error: Unable to lock maildrop : Mailbox is locked by POP server. I can see where it starts in the log. I've read that there is no physical lock file anymore (i've tried looking for it anyways) and that the solution is to just wait for the timeout, or kill the offending pop3 process. I know that this is happening because of a lossy connection on the part of the affected user, and that pop3 can only have 1 session active at a time. I need to manually clear the lock and I am having trouble finding the offending pop process. I have tried lsof, but it doesn't say how long the individual files (sockets) have been opened for. I've reduced the tcp keepalive time down to 5 mins, but I still need to reset this guy's lock. I could use some pointers. Thanks!

• How do I upload huge files across the internet without using P2P?

  - by Brien Malone

  I work remotely and have 44GB of media files that I need to send back to my office. There are lots of free services out there that can handle up to 2GB, but I haven't seen talk of anything larger. We both have 50mbps+ connections, so I would rather not mail physical media (though, that is an option). Bittorrent is blocked at my corporate headquarters. We have an FTP server, but the per-user cap is 10GB. I use Citrix, but throughput is throttled to 3mbps. (44gb @ 50mbps = 4 to 5 hours... @3mbps = 5 or 6 days.) Any suggestions appreciated. Windows 7 and Windows 2003 Server are the OSes Involved I have tried JetBytes and it is blocked by our content filter

• One bigger Virtual Machine distributed across many OpenStack nodes [duplicate]

  - by flyer

  This question already has an answer here: Can a virtualized machine have the CPU and RAM resources of multiple underlying physical machines? 2 answers I just setup virtual machines on one hardware with Vagrant. I want to use a Puppet to configure them and next try to setup OpenStack. I am not sure If I am understanding how this should look at the end. Is it possible to have below architecture with OpenStack after all where I will run one Virtual Machine with Linux? ------------------------------- | VM with OS | ------------------------------- | NOVA | NOVA | NOVA | ------------------------------- | OpenStack | ------------------------------- | Node | Node | Node | ------------------------------- More details: In my environment Nodes are just virtual machines, but my question concerns separate Hardware nodes. If we imagine this Nodes(Novas) are placed on a separate machines (e.g. every has 4 cores) can I run one Virtual Machine across many OpenStack Nodes? Is it possible to aggregate the computation power of OpenStack in one virtual distributed operating system?

• Help creating image from LVM

  - by jackhab

  I need to duplicate CentOS hard drive image for multiple stations. The HD has the following layout: Disk /dev/sdb: 250GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 107MB 107MB primary ext3 boot 2 107MB 250GB 250GB primary lvm I saved /dev/sdb1 to file with fsarchiver but for sdb2 I get: /fsarchiver savefs an2.fsa /dev/sdb2 oper_save.c#1006,filesystem_mount_partition(): can't detect and mount filesystem of partition [/dev/sdb2], cannot continue. removed an2.fsa Although fsarchiver probe simple correctly detects sdb2 as LVM2_member. Is fsarchiver correct tool for this job? What's wrong? I'm on Ubuntu 9.1 with fsarchiver 0.6.8 and lvm tools installed. Thanks.

• apache and ajp performance

  - by user12145

  I have an apache sitting in front of two tomcat app servers(one on the same physical server, the other on a different one) that does time consuming work(0.5 sec to 10sec per request). The apache http server is getting killed by an average of 1 to 2 concurrent requests per second. both Server spec is about 2GB of RAM. Is there a way to optimize apache to handle the load? any advise is welcome. BalancerMember ajp://localhost:8009/whoisserver BalancerMember ajp://XXX.XX.XXX.XX:8009/whoisserver I keep getting the following in apache2.2 log: [Mon Dec 28 00:31:02 2009] [error] ajp_read_header: ajp_ilink_receive failed [Mon Dec 28 00:31:02 2009] [error] (120006)APR does not understand this error code: proxy: read response failed from 127.0.0.1:8009 (localhost)

• Windows 7 - Move location of Eventlog

  - by Jörg B.

  I am having a particular nasty problem of my main system drive 'disappearing' all of the sudden while the system is running. The vendor somewhat knows about this but has not managed to fix it completely over multiple fw iterations. Problems I have with the support is that I cannot provide any particular system log files/entries to further analyse what might have been going on because, well - windows cannot write to its 'lost' drive before bsod'ing. Is there any way to configure where Windows 7 stores its event logs so that I could specify a second physical hdd?

• Starting x11vnc remotely when X server is already running

  - by Madiyaan Damha

  I have a ubuntu linux machine that I have already logged into and X server is running (it is pass the login manager like gdm). I can access this machine through ssh. My goal is to start x11vnc on this machine and attach it to the X server that is already running. When I ssh into the machine and start x11vnc, it says: X11 was unable to open the X DISPLAY ":0", it cannot continue. How can I start x11vnc on the remote machine if I don't have physical access to it and Xserver has already started. The reason I want to do this is because the remote machine has several windows open that I want to work on. Thanks,

• Creating a 64bit build in Visual studio

  - by user48408

  I have an old .net 2.0 windows app I need to deploy on a windows 7 machine and its not going too well. I want to build a native 64 bit version rather than a 32bit capable of running on a 64bit environment. I'm working with Visual studio 2005 My question is what settings do I need to set within each project of my solution, (both the windows app + my dll's that it references) and what settings i should set on my install project (I have a deployment project for distribution)

• Can the Microsoft Paint Edit Colors Dialog be supplemented?

  - by Gus

  I have written a WinForms application that presents a color picker, limited to the known colors. My environment is Visual Studio C# Express 2008, C#, and Framework 2.0. Currently the MS Paint Colors menu item only presents an Edit Colors dialog. I would like to supplement that by causing the Colors menu item to display both "Edit Colors" and "Edit Known Colors". Can I accomplish this? If so, please provide a citation (or code if preferrred).

• Distributing entropy to virtual machines.

  - by Louis

  Dear All, I'm interested in generating secret keys for SSL on virtual machines using true randomness. By true randomness I mean the same level of entropy that can be generated by UNIX's dev/random and entropy gathering daemon (EGD). Is there a "general knowledge" recipe to route entropy from the physical layer to the virtual machines via the hypervisor regardless of the Hypervisor/Guest OS combination? Example: suppose one "hypervises" with VMware VSphere and instantiates Windows Guest OS. Can this hypervisor collect entropy from its peripherals (like dev/random/ would) and distribute it to these guest Windows OS? When considering the big vendors (VMware, Hyper-V, Citrix, etc), do they have entropy pools that gather entropy that can easily be pushed to their respective virtual machines? Louis

• Strategy to allow emergency access to colocation crew

  - by itsadok

  I'm setting up a server at a new colocation center half way around the world. They installed the OS for me and sent me the root password, so there's obviously a great amount of trust in them. However, I'm pretty sure I don't want them to have my root password on a regular basis. And anyway, I intend to only allow key-based login. On some cases, though, it might be useful to let their technical support log in through a physical terminal. For example, if I somehow mess up the firewall settings. Should I even bother worrying about that? Should I set up a sudoer account with a one-time password that will change if I ever use it? Is there a common strategy for handling something like this?

• USB to USB CD ROM emulator

  - by JohnnyLambada

  I'm wondering if anyone knows of a CDROM emulator that runs on Linux. I want to emulate this configuration: [CDROM DRIVE]----USB CABLE----[COMPUTER UNDER TEST] Where [COMPUTER UNDER TEST] is a computer that boots from a physical CD inserted into the [CDROM DRIVE]. Only instead of the [CDROM DRIVE] I want the following configuration: [CD IMAGE BUILD MACHINE]-----USB CABLE-----[COMPUTER UNDER TEST]. I want to build an ISO image on the [CD IMAGE BUILD MACHINE] and have some sort of USB CDROM emulator running on it to serve up the ISO image to the [COMPUTER UNDER TEST] as though it was talking to the [CDROM DRIVE]. Does this exist? If it does, I can't find it. I want to do this so I can test out bootable CDs without burning a lot of coasters.

• Single sign-on for SharePoint to MySite?

  - by Chris W

  I've got a fairly simple SharePoint 2010 farm set up: 2 WFE servers with Network Load Balancing hosting the main portal site. As per Microsoft's best practice recommendations I've set up My Sites in a separate web application. As some of the user base are not using domain joined PCs they have to login once for the portal (http://portal) and then again when the access My Sites since they're crossing in to a separate web application on a separate host (http://mysite). Portal & MySite are both hosted on the same physical WFE servers. Is there an easy way to set up some thing to stop this happening and just have them login once? I understand that there's plans for us to deploy ISA in the not too distant future - could we use ISA to manage authentication to the two sites so that the users only need to log in once?
