• View subset of files in folder in Windows 7

  - by dev5

  I have a folder with a thousands of files in it. There is a subset of about 100 files which i need to work with consistently. Is there a way to create some sort of virtual folder or view which only contains these files.

• port forwarding with VirtualBox

  - by Argh

  I have a virtualbox VM running ubuntu. The Ubuntu guest is running a web server which listens on port 3000 (http://127.0.0.1:3000) The host machine is windows vista. I have configured port forwarding using VBoxManage. If I query the config using VboxManage getextradata "MyMachine", I get Key: GUI/AutoresizeGuest, Value: on Key: GUI/Fullscreen, Value: off Key: GUI/LastCloseAction, Value: shutdown Key: GUI/LastWindowPostion, Value: 9,34,640,529,max Key: GUI/MiniToolBarAlignment, Value: bottom Key: GUI/MiniToolBarAutoHide, Value: off Key: GUI/SaveMountedAtRuntime, Value: yes Key: GUI/Seamless, Value: off Key: GUI/ShowMiniToolBar, Value: yes Key: VBoxInternal/Devices/pcnet/0/LUN#0/Config/guesthttp/GuestPort, Value: 3000 Key: VBoxInternal/Devices/pcnet/0/LUN#0/Config/guesthttp/HostPort, Value: 3000 Key: VBoxInternal/Devices/pcnet/0/LUN#0/Config/guesthttp/Protocol, Value: TCP This looks like it should work... However when I try to access the web server from the host machine (windows box) I dont get a response. I ran a netstat on the windows box and nothing appears to be listening on port 3000 which explains why forwrding isnt working. Note that I have already tested with my firewall switched off... The version of VirtualBox I am using is 3.1.4 Any ideas?

• Linksys/Cisco Small Business SRW-Series (ie SRW248G4) - Overcoming the Limitations

  - by Warren P

  We just purchased a Cisco/Linksys SRW 248G4 switch to try it out. We have always had unmanaged switches before, and this is our first "somewhat managed" switch. So far the major limitations are: Only Internet Explorer 6 (manual says IE 5.5!) works for the web interface SSH exists but is not practically useable because the only key length that is supported is no longer even used by most modern SSH installs. (I get the error "RSA modulus too small" in openssh 4.x/5.x) This is with the latest firmware revision, I believe, although Cisco's website does not actually tell you what version you're downloading. All in all, I think, they must be trying to tell me that if I want a good-quality switch, I shouldn't buy these SRWs and should buy a Dell or an HP ProCurve, or save up my pennies, and buy a Catalyst. The question here, then, at long last: Has anyone gotten the web-browser to work via some IE 7 or IE 8 compatibility mode settings or used another browser (Opera? KDE/Safari/WebKit?) and spoofed IE6? Is there any way to get the SSH key length upgraded? I'm guessing a 0% chance of a yes on that last one. I found an XP machine, used telnet (via PuttyTel.exe) and IE6 to set this up, and I doubt we'll have to touch it again. Which is fine with us. But it would be nice if I could administer this thing from either (a) a linux box, or (b) my primary desktop which is windows 7. It looks like XPMode with IE6 on the virtual XP machine may be my only way to administer this type of switch via the web.

• Using Cisco VPN in Windows 7 XP Mode?

  - by Shane

  I previously asked a question about whether it was possible to use Cisco VPN client on Windows 7 64-bit (see below). Now that I have it set up, it doesn't work when I try to connect off the local network. I realize that there must be some networking/routing that I need to do since it's running on a virtual machine. How does one go about using the Cisco VPN client from XP mode in Windows 7? Related: Cisco VPN Client on Windows 7 64-bit?

• Can't remotely connect through SQL Server Management Studio

  - by FAtBalloon

  I have setup a SQL Server 2008 Express instance on a dedicated Windows 2008 Server hosted by 1and1.com. I cannot connect remotely to the server through management studio. I have taken the following steps below and am beyond any further ideas. I have researched the site and cannot figure anything else out so please forgive me if I missed something obvious, but I'm going crazy. Here's the lowdown. The SQL Server instance is running and works perfectly when working locally. In SQL Server Management Studio, I have checked the box "Allow Remote Connections to this Server" I have removed any external hardware firewall settings from the 1and1 admin panel Windows firewall on the server has been disabled, but just for kicks I added an inbound rule that allows for all connections on port 1433. In SQL Native Client configuration, TCP/IP is enabled. I also made sure the "IP1" with the server's IP address had a 0 for dynamic port, but I deleted it and added 1433 in the regular TCP Port field. I also set the "IPALL" TCP Port to 1433. In SQL Native Client configuration, SQL Server Browser is also running and I also tried adding an ALIAS in the I restarted SQL server after I set this value. Doing a "netstat -ano" on the server machine returns a TCP 0.0.0.0:1433 LISTENING UDP 0.0.0.0:1434 LISTENING I do a port scan from my local computer and it says that the port is FILTERED instead of LISTENING. I also tried to connect from Management studio on my local machine and it is throwing a connection error. Tried the following server names with SQL Server and Windows Authentication marked in the database security. ipaddress\SQLEXPRESS,1433 ipaddress\SQLEXPRESS ipaddress ipaddress,1433 tcp:ipaddress\SQLEXPRESS tcp:ipaddress\SQLEXPRESS,1433

• Network monitoring tools with API features

  - by Kev

  We use ks-soft's Advanced Hostmonitor package to monitor around 2000 items on our network. We think it's great, the chap that supports it is fantastic, the product is fast, stable and mature but I feel as as we grow as a company it's beginning to show some friction points in the area of integration with our back office admin systems. One of the things we'd like to do is be able to add new tests to whatever monitoring tool we use via an API. For example, when orders for servers come from our retail interface, the server gets built automatically, and as part of the automated build process we'd like to automatically add new tests to the network monitoring systems. Hostmonitor has some support for this via a feature called HM Script but we're starting to encounter some speedbumps - we can't add new operators/users we can't define new "Action Profiles" - these are the actions to be taken when a test goes good or bad. What we love about hostmonitor though are the Action Profiles. For example if a Windows IIS box goes bad our action profile for a bad test does something like: Check host again (one time) Wait another 30 seconds then test again Try restart app pool on remote machine (up to two times) Send an email to ops about the restart failure Try restarting IIS on remote machine (up to four times) Page duty admin (up to 5 times - stops after duty admin ACKS alert) Page backup duty admin (5 times - stops after duty admin ACKS alert) I'm starting to look around at other network monitoring tools and I'm looking for: a comprehensive API to be able to add/remove/control tests/test "action profiles"/operators (not just plugins, we need control and admin interfaces) the ability to have quite detailed action/escalation profiles (and define these via an API) I've looked at Nagios and Icinga but Ican't seem to glean from their documentation whether we could have these features or not, or if we could, how much work would be involved to implement/customise. Can anyone provide any advice, guidance or experiences?

• Windows Server 2008 R2 SP1 Drivers Missing Would Not Install?

  - by bleepzter

  I am building my dev machine with WS2008R2SP1. I consider Windows Server as the best development environment for C# since I tend to focus on server-centric (integration) applications. The desktop flavor of Windows (7) doesn't play nicely with things like Commerce Server or BizTalk... so I to like stick to the environment I develop for. Previously I used to develop inside of VM's but I've found that it is super inefficient and tends to take a toll on the laptops. (I've gone through two of them in 6 months). Problem is that I multiple devices that do not want to be recognized by Windows: My machine is Dell Precision M4500: Intel Core i7-Q740, 1TB HDD, 8GB RAM, Dell re-branded Broadcom DW1501 802x11n Half-Mini Card, Dell re-branded Broadcom DW375 Bluetooh Module, Intel 82577LM Gigabit Network connection NVidia Quadro FX1800 Graphics The devices in question are the Dell rebranded broadcom network and bluetooth adapters: Broadcom USH: USB\VID_0A5C&PID_5800&REV_0101&MI_00 USB\VID_0A5C&PID_5800&MI_00 DW375 Bluetooth Module USB\VID_413C&PID_8187&REV_0517 USB\VID_413C&PID_8187 When I ran the broadcom installers I get "Operating System not supported" which I think is a big oversight on Broadcom's part. Why check for system version string? UGHGHGH Moreover if I try to manually force the driver in windows... I get an error: Driver Management concluded the process to install driver FileRepository\btwampsecfl.inf_amd64_neutral_d8fc2b85d035ed47\btwampsecfl.inf for Device Instance ID USB\VID_0A5C&PID_5800&MI_00\7&66DE6C9&0&0000 with the following status: 0xe0000217.

I googled the 0xe0000217 error code and it says Bad service install section in the driver inf file... Any ideas on how to fix this?

• HP Storageworks 448 tape drive input/output error with Ubuntu

  I'm trying to set a backup to tape of a machine using flexbackup. However any attempt to write to the tape drive (via either flexbackup or just tar) results in "/dev/st0: Input/output error" The machine seems to recognise the drive (HP Storageworks Ultrium 448) and that there's a tape in it and "mt status" seems to work...

• ZFS - destroying deduplicated zvol or data set stalls the server. How to recover?

  - by ewwhite

  I'm using Nexentastor on a secondary storage server running on an HP ProLiant DL180 G6 with 12 Midline (7200 RPM) SAS drives. The system has an E5620 CPU and 8GB RAM. There is no ZIL or L2ARC device. Last week, I created a 750GB sparse zvol with dedup and compression enabled to share via iSCSI to a VMWare ESX host. I then created a Windows 2008 file server image and copied ~300GB of user data to the VM. Once happy with the system, I moved the virtual machine to an NFS store on the same pool. Once up and running with my VMs on the NFS datastore, I decided to remove the original 750GB zvol. Doing so stalled the system. Access to the Nexenta web interface and NMC halted. I was eventually able to get to a raw shell. Most OS operations were fine, but the system was hanging on the zfs destroy -r vol1/filesystem command. Ugly. I found the following two OpenSolaris bugzilla entries and now understand that the machine will be bricked for an unknown period of time. It's been 14 hours, so I need a plan to be able to regain access to the server. http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6924390 and http://bugs.opensolaris.org/bugdatabase/view_bug.do;jsessionid=593704962bcbe0743d82aa339988?bug_id=6924824 In the future, I'll probably take the advice given in one of the buzilla workarounds: Workaround Do not use dedupe, and do not attempt to destroy zvols that had dedupe enabled. Update: I had to force the system to power off. Upon reboot, the system stalls at Importing zfs filesystems. It's been that way for 2 hours now.

• In Windows 7, why can't I use perfmon against a remote server?

  - by SomeGuy

  I am on Windows 7 and trying to run perfmon against Windows 2003 and Windows 2008 servers. I am running into the same issue with all remote machines. When creating a data collector set, I specify a domain account that is in the administrators group on the remote machines (and "Performance Log Users" and "Performance Monitor Users" to be safe). On the "Available Counters" screen, When I type in a remote computer name, PerfMon locks up for a good 2-3 minutes before I can add any counters. I can then save the collector set. However, when I save it, the go/stop buttons are disabled if I click the set in the left panel, and missing if I click the Data collector set itself in the right panel. See the screens below. I can run data collector sets against my local machine with no problem. I am opening perfmon with my local account in both scenarios. I also have Remote Registry Service started on each remote machine. What is going on?

• Routing multiple static IPs from ISP at the cable modem?

  - by Jakobud

  I'm taking over IT responsibilities for a previous IT guy. We have a 50mb cable modem connection from Comcast along with 5 static IP addresses: XXX.XXX.XXX.180 XXX.XXX.XXX.181 XXX.XXX.XXX.182 XXX.XXX.XXX.183 XXX.XXX.XXX.184 We are in the process of replacing our firewall machine. Currently the firewall box is the only thing connected to the cable modem. However the cable modem has multiple ethernet ports on it, similarly to a router. I have assembled a new firewall machine and its time to start testing and configuring it. So that means that I also need it plugged into the cable modem (remember it has multiple ethernet ports on it). So now with multiple computer plugged into the cable modem, how does the cable modem know where to route the traffic? If some request on the internet is made to XXX.XXX.XXX.181, which goes to our cable modem, how does the cable modem know which connected computer that traffic is supposed to be sent? Looking at the web interface for the cable modem, there doesn't seem to be anything special setup on it with regards to routing or NATing IP addresses. Is that because when there is only one computer connected to the modem, all traffic is sent to it by default? Now that I am going to (temporarily) have multiple computers plugged into the cable modem, do I need to specify routing or NAT rules on the modem itself? I am going to speak to Comcast about this next, but I figured I'd ask here first just so I can get a better grasp on how this type of thing generally plays out.

• "A disk read error occurred" when booting XP disk image in VirtualBox

  - by intuited

  I'm trying to boot an XP installation cloned into VirtualBox from a real drive. I'm getting the message A disk read error occurred Press Ctrl+Alt+Del to restart whenever* I try to boot the machine. * This is not strictly true: with AMD-V enabled, the boot process appears to not make it this far and instead hangs at a black screen with cursor. I created the VirtualBox image from the original drive using the following method: $ sudo ddrescue -n /dev/sdd sdd.img logfile # completed without errors $ VBoxManage convertfromraw sdd.img disk.vdi The original disk (and the image) contain a single NTFS partition with XP installed on it. The owner of the drive indicates that it did boot okay the last time the system made it that far. The (Pentium 4) system has a broken (enormous) heat sink, so at some point it failed to boot because it would quickly overheat and shut down. If I boot the VM from a live cd, I am able to mount its /dev/sda1 without any problems. I ran ntfsfix and didn't have any luck. I've read through the instructions on doing this. I didn't really follow them. For example, I didn't run MergeIDE before imaging because the machine was not bootable. However, the symptom of that problem seems to be quite different. The emitted message is contained in the volume boot record of the XP partition, which leads me to suspect that this is a problem with the core operating system bootstrap procedure, and not related to anything in the registry. I don't have an XP boot CD.

• Persistent static route stops working after VPN drops and reconnects

  - by user76157

  I've got a VPN between two networks, one home and one office (A and B). Their subnets are: (A) 192.168.1.0 and (B) 192.168.0.0 The two networks have identical ADSL routers. Unfortunately these can only do dial-out VPN. So I've got a Windows 2008 server on Network B acting as a VPN server (ServerB). Network A's router (RouterA) passes through Network B's router and connects via PPTP to ServerB. RouterA is assigned the static IP 192.168.0.40 on Network B. There's a persistent static route on ServerB telling it to use 0.40 for all requests to Network A's subnet, 192.168.1.0. (route -p add 192.168.1.0 mask 255.255.255.0 192.168.0.40). This enables ServerB to ping all machines on A (and those machines to ping ServerB). The VPN connection occasionally drops (I'm not sure why - it's set to remain always on and seems to drop randomly). This wouldn't be too much of a problem, as it reconnects automatically and quickly, except that when it does reconnect, the static route on ServerB no longer works. Route print (on ServerB) shows that the persistent static route still exists. However a tracert to a machine on Network A doesn't use the static route; it tries instead to use ServerB's default gateway (which is RouterB), and fails to find the machine. Deleting and re-adding the static route fixes the problem - a tracert uses the static route. At the moment, a batch file to delete and re-add the static route is scheduled to run every day. But this is clearly far from an ideal solution! I hope that's not too confusing. Any help would be very much appreciated.

• Cannot run a VM with more than three network interfaces with KVM

  - by Bostonvaulter

  I'm running KVM on top of Ubuntu 10.10 Server I can create VM's (Virtual Machine) and network interfaces fine but I cannot seem to add more than three network interfaces. As soon as I have a VM with four network interfaces it gets stuck on startup at the starting SeaBIOS page with this message: Starting SeaBIOS (version pre-0.6.1-20100702_143500-palmer) So far I've verified this with two VM's, a Ubuntu 10.10 desktop and a Vyatta router. The specific network hardware I assign to the VM's doesn't seem to matter. I'm trying to have one bridged interface and three private networks using Vyatta to route between them. Does anyone know why I can't run a VM with more than three network interfaces? Edit: Additionally the KVM thread responsible for the specific VM hangs using ~100% CPU (i.e. one core). Here's the command for the process that is hanging: /usr/bin/kvm -S -M pc-0.12 -enable-kvm -m 512 -smp 1,sockets=1,cores=1,threads=1 -name vyatta -uuid 6dff7c94-6810-423e-5fea-fec10da0e9b7 -nodefaults -chardev socket,id=monitor,path=/var/lib/libvirt/qemu/vyatta.monitor,server,nowait -mon chardev=monitor,mode=readline -rtc base=utc -boot c -drive file=/home/rams/virtual-machines/vyatta.img,if=none,id=drive-ide0-0-0,boot=on,format=raw -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0 -drive if=none,media=cdrom,id=drive-ide0-1-0,readonly=on,format=raw -device ide-drive,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -device rtl8139,vlan=0,id=net0,mac=00:54:00:be:cc:4b,bus=pci.0,addr=0x3 -net tap,fd=97,vlan=0,name=hostnet0 -device rtl8139,vlan=1,id=net1,mac=52:54:00:da:59:ed,bus=pci.0,addr=0x5 -net tap,fd=98,vlan=1,name=hostnet1 -device rtl8139,vlan=2,id=net2,mac=52:54:00:ce:22:b6,bus=pci.0,addr=0x6 -net tap,fd=99,vlan=2,name=hostnet2 -device rtl8139,vlan=3,id=net3,mac=52:54:00:1e:bc:46,bus=pci.0,addr=0x7 -net tap,fd=101,vlan=3,name=hostnet3 -chardev pty,id=serial0 -device isa-serial,chardev=serial0 -usb -vnc 127.0.0.1:0 -k en-us -vga cirrus -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x4 Edit: I've also found an error in dmesg that might be related (it also shows up when running virtd in verbose mode): 14:47:24.399: warning : qemudParsePCIDeviceStrs:1422 : Unexpected exit status '1', qemu probably failed I've also tried disabling app armor but that doesn't seem to make a difference.

• Sending Adobe PDF attachments from Adobe Reader (in Outlook 2003) takes too long

  - by White Island

  I have a customer who is using Outlook 2003 (Microsoft Online Services) and Adobe reader 9+. When they send a PDF from Adobe reader to Outlook (via the Send as attachment to e-mail feature in Adobe), it freezes for 30 seconds to 5 minutes before the new e-mail pops up with the PDF attachment. I'm pretty sure the issue is on the Outlook side of things, as I've tried Adobe reader 8 and Foxit Reader with the same results (Windows XP/7 doesn't seem to make a difference, either). I tried Outlook in safe mode on the first (Win7) machine I was working on, and the e-mail attachment worked a lot faster, but when I tried to replicate the results on another machine, one wouldn't go into safe mode, the other didn't seem to show a difference. In an effort to fix the problem in Outlook normal mode, I tried disabling all add-ins, Com add-in (Office Communicator is the only one), reading pane, Word 2003 as e-mail editor... but none of these seemed to address the issue. Does anyone have any other ideas? I need to get this resolved as soon as possible, and it doesn't seem practical to make them run in safe mode. :P

• ASUS P8B WS - Endless Reboots

  - by tuxGurl

  I am running a Intel XEON 1245 with 4GBx2 Kingston Memory ECC Unbuffered DDR3 on an ASUS P8B WS motherboard. BIOS Version 0904 x64. This system is a little over a month old. It is running Ubuntu 11.10. This evening I found the machine turned off. When I tried to restart it, it would POST and stop at the GRUB screen. When I selected Ubuntu and hit enter within 2-3 seconds the would shutdown and restart. If I stayed at the GRUB screen and did nothing the system would not cut out. I tried booting off a USB stick and again 2-3 seconds after selecting 'Try Ubuntu without Installing' the machine will cut power and reboot. Things I have tried so far: Resetting the BIOS using the on board jumper Resetting the BIOS settings to default Disconnecting all external hardware - except keyboard & monitor Booting with 1 stick of RAM - I tried different single sticks Ensured that onboard EPU and GPU boost switches are in the off position. I am running a Memtest86 right now and it has been running for 38+ minutes. This is not an OS problem or an overheating issue (I have a CoolerMaster HAF Case with 3 fans besides the CPU fan) I am at a loss as to what to try next. I think the BIOS is mis-configured somehow but I don't know what to look for.

• Virtualbox Headless Server on Ubuntu missing VRDP Options

  - by The Daemons Advocate

  I'm running VirtualBox headless server on an Ubuntu 64 bit host, and I want to use it remotely. However, I'm having problems connecting via RDP. The DNS names in my network show the host to be 'server', and the guest to be 'ubuntu-vm'. From the official documentation, I gather that I am to connect to server on the default RDP port in order to see the guest machine. I start the virtual machine like so: vboxheadless -startvm My_VM Then I connect on my laptop, and I get... rdesktop -a 16 server ERROR: server: unable to connect So next I consult the documentation further, and I find there are RDP flags that can be turned on (but should be on implicitly for a headless server). So I pull up information using 'vboxmanage showvminfo My_VM', and I find the VRDP property is off. VRDP Connection: not active To make things even weirder, RDP flag seems to be missing from vboxmanage. I've installed straight from the ubuntu repo's using the virutalbox-ose package, not sure how that measures up against the official docs. For instance, this command doesn't exist: VBoxManage modifyvm My_VM --vrdp on From the UI, the VM's Settings regarding Display have greyed out the 'remote Display' option. What I'm looking for is advice :). I'm open to suggestions that don't involve starting again with something like VMWare. Thanks in advance!

• Dual VGA monitors with Quadro FX 580?

  - by dentrasi

  I have a machine with a Quadro FX 580 card (DVI and two Displayport). Attached to it are two 19" Acer screens, which are both (annoyingly) VGA. The first one works perfectly, with a DVI-VGA adaptor. The second one doesn't work. It's got a VGA cable, which goes into a VGA-DVI converted, which then goes into a DVI-Displayport converter. Initally, I was getting 'Cable Unplugged' on the screen, and it couldn't be seen by Windows or the nVidia control panel. After swapping the VGA-DVI adaptor (which works perfectly on another machine), Windows can now see the monitor. The nVidia panel sees the model and native resolution, but I get a constant 'No Signal' error. Switching to the other Displayport makes no difference. I suspect that the card is seeing a DVI connection plugged into it (nVididaCP shows the monitor as having a DVI connection), and it only sending out a digital signal because of this. Does anyone know of a solution (other than trying to get a Displayport-VGA adaptor), or of a way to force the card to see it as VGA? Thanks, ~Dentrasi

  I moved the question to here from stackoverflow.com http://stackoverflow.com/questions/2917569/unable-to-ping-server-from-client-b-but-able-to-ping-from-client-a-please-help I am trying to configure a IIS 6.0/Windows Server 2003 web server with a ASP.net application.

• Wamp virtualhost with supporting of remote access

  - by Farid

  To cut the long story short, I've setup a Wamp server with local virtual host for domain like sample.dev, now I've bind my static IP and port 80 to my Apache and asked the client to make some changes in his hosts file and add x.x.x.x sample.dev , I've also configured my httpd virtual host like this : <VirtualHost *:80> ServerAlias sample.dev DocumentRoot 'webroot_directory' </VirtualHost> Client can reach to my web server using the direct access by ip address, but when he tries using the sample domain looks like he gets in to some infinite loop. The firewall is off too. What would be the problem?! Thanks.

• Windows 7 disk backup and clone for deployment to multiple systems

  - by gregmac

  I'm in the process of deploying some new PCs (there's only 8), all identical hardware. What I'd like to do is install Windows 7 (64bit), join to domain etc, install a bunch of other software, and then clone that drive to multiple other machines. I'd also like to be able to use it as a backup image, so the machine can be restored back to that image at some future date. I understand this involves at least sysprep, but I am confused after reading some tutorials that talk about using Windows Automated Installation Kit, or hacks with the registry and custom-build batch files. This process seems overly complex to me: I did something similar 10+ years ago, and and don't remember it being this bad. Surely things have improved in a decade? There's also some products that involve having network servers running deployment software, network boot, etc etc.. this is way more than I want to set up. My systems are all identical hardware. Is there a simplified way to clone PCs? Preferably (since I'm a lazy developer, and not an IT admin) I'd like to find some off-the-shelf product that I can run after I get the machine setup, that will spit out a bootable DVD I can run on all the other systems, which will boot up, ask for a computer name, join it to the domain, and that's it. Does such as product exist?

At the moment to click on the virtual machine it launche the terminal and afetr a few seconds a messages popup appears saying: juniper terminal services client has stopped working When I had windows 8 I was able to run Juniper without any problem. But in Windows 8.1 seems there are compatibilities issues. Any suggestion, solution or workaround? Thanks in advance

• AWS lighttpd: Sending a copy of requests to test.

  - by Martin

  I have a load balanced service on AWS. So the ELB evenly distributes the load across my servers. Each server is running lighttpd that does logging and forwards the requests to my service (on the same machine). I have written a new version of the service. It is installed and running on an EC2 machine test1 (basically a mirror of our current server but the new service running instead of the original) and I have done some preliminary tests that look good. But what I would like to do is mirror a fraction of incoming traffic to the new version of the service so I can do some comparisons between an original version and the new version based on real traffic. Thus I was thinking I could modify one box behind the ELB to duplicate its traffic to the test1. I was thinking I could modify the configuration of lighttpd so that each request is mirrored/duplicated. i.e. the original service keeps responding as before but a mirror request is sent to test1 but the reply is just dropped). Unfortunately I have not been able to work this out. Any ideas on how I could mirror the requests from one box to itself and test1. Or any other ideas for testing.

• Hyper-V Guests Dying

  - by Jon Rauschenberger

  I just hit my THIRD instance of a Hyper-V guest machine dying with the exact same behavior. In all three instances we are hosting WS2008 guests on a WS2008 host. AFter a config change, we reboot the guest and the guest OS comes up but in a very cripled state. Specifically, we are able to log into the guest, but can't launch any apps and the guest never comes active on the network. I opened a support ticket with MS the second time this happened and they focused in on the DCOM subsystem not coming up...best explanation they could provide was that permissions on key system files got corrupted. I eventually gave up on the ticket after close to 10 hours on the phone trying different things that were going no where. What really concerns me is that we have now seen the exact same thing happen to a guest hosted on a completly differet host machine. There is zero hardware overlap between the two. Has anyone seen this before?? It's really odd behavior, but it also seems like there's a pattern here that's concerning me. Thanks, jon
