• Unable to create a VSS snapshot of the source

  - by SuperFurryToad

  The following error is preventing me from cloning a Windows 7 64bit computer. Unable to create a VSS snapshot of the source volume(s). Error code: 2147754754 (0x80042302) I'm using VMWare vCenter Converter Standalone Client 4.0.1. Any ideas on what might be causing this? When I checked the services running, I noticed that the Volume Shadow Copy Service was set to manual. So I started the service and switched it to automatic. It still didn't work after that. I checked the event logs and I got the following errors: Event ID: 22 Description: Volume Shadow Copy Service error: A critical component required by the Volume Shadow Copy service is not registered. This might happened if an error occurred during Windows setup or during installation of a Shadow Copy provider. The error returned from CoCreateInstance on class with CLSID {e579ab5f-1cc4-44b4-bed9-de0991ff0623} and Name IVssCoordinatorEx2 is [0x80040154, Class not registered Event ID: 8193 Description: Volume Shadow Copy Service error: Unexpected error calling routine CoCreateInstance. hr = 0x80040154, Class not registered

• VirtualCenter Server service terminated with service-specific error 2 (0x2).

  - by LucD

  Hello! This is not a critical case but really annoying. I'm running vCenter 4 (Build 208156) and when we reeboot the server the VirtualCenter Server service can't start and gives the following error "The VMware VirtualCenter Server service terminated with service-specific error 2 (0x2)." And if I try to start the service it fails again giving the same error. What I'll need to do is to stop the IIS Admin service and then start the VirtualCenter Server service and then the IIS Admin service, and everything runs fine until the next reboot. Can someone tell me how to fix this annoying error? Regards

• Enabling SFTP Access within PLESK

  - by spelley

  Hello everyone, I have a client who wants to ensure his upload is secure, so we are trying to enable SFTP for him on our Linux PLESK server. I have enabled SSH access to bin/bash for FTP accounts, and created a new user. When I attempt to SFTP using either the IP address or the domain name, this is the error FileZilla is giving me: Error: Authentication failed. Error: Critical error Error: Could not connect to server Here is some basic information regarding the server: Operating system Linux 2.6.24.5-20080421a Plesk Control Panel version psa v8.6.0_build86080930.03 os_CentOS 5 I had read in some places that I should reboot the SSH Service in Server - Services, however, there is no SSH Service within the list. I'm not really a server guy so it's quite possible I'm missing something obvious. Thanks for any help that you guys can provide!

• Zimbra server status showing red in control panel

  - by Debianuser

  I have been having a weird problem with Zimbra(7.1.4_GA_2555.DEBIAN5) lately: On the (web)control panel the status keep changing to red every few days. When this is happens the output of zmcontrol status still shows running: antispam Running antivirus Running imapproxy Running ldap Running logger Running mailbox Running memcached Running mta Running snmp Running spell Running stats Running zmconfigd Running Every thing runs fine except automated mail forwarding from one account to another(which is critical for us). I have been through Zimbra forums and the following ALWAYS fixes the issue: su - zimbra -c "zmprov mcf zimbraLogHostname mail.mydomain.com" /opt/zimbra/libexec/zmsyslogsetup /etc/init.d/rsyslog restart su - zimbra -c "zmcontrol restart" After I run the above commands, the status on control panel turns green and mail forwarding starts to work again BUT only for a few days. Other than the above, everything works fine including Server statistics. Anyone seen this issue before?

• Windows update doesn't list update details, only the number of updates

  - by leodip

  Hi all, My system is Vista Business 32 bits SP2. When I click "Windows update", I can see there are 2 available optional updates. If I click the link "2 optional updates are available" to see what the updates are, I get: http://leodip.s3.amazonaws.com/windows%5Fupdate2.PNG The details about the updates are EMPTY. Any idea why this is happening? It doesn't happen only with optional updates, but with critical updates as well. I would like to fix this, so I can see what the updates are. Thanks!

• Google's Search Box in SharePoint

  - by Evan M.

  Has anyone here looked at the Google Search Box for SharePoint? We're looking into it as part of our MOSS deployment since we also use Google's GSA, and I'm personally not impressed with it, while a colleague seems to think that it's the only option we should be using, or even considering. While I've got no problems with the GSA indexing our SharePoint content, the Search Box just seems clumsy. It looks horrible, the results being returned are much more limited than what I get if I use the GSA search page itself, configuring it has been nothing but a PITA and it's still only got a basic config ans isn't respecting things like user permissions or search scopes that the default SharePoint Indexer and search controls handle out of the box. What are your guys thoughts? Am I being overly critical, and should just spend more time trying to configure it? Are you using a split-personality with it yourself, where you have the GSA for enterprise wide search, but use SharePoint for local searches? Other thoughts?

• Icinga error "Icinga Startup Delay does not exist" although it does

  - by aaron

  I just installed icinga to monitor my server following this guide: http://docs.icinga.org/0.8.1/en/wb_quickstart-idoutils.html Everything built and installed correctly, but icinga is reporting a critical error with the reason: "The command defined for service Icinga Startup Delay does not exist" However, I can see that ${ICINGA_BASE}/etc/objects/localhost.cfg contains: define service{ use local-service ; Name of service template to use host_name localhost service_description Icinga Startup Delay check_command check_icinga_startup_delay notifications_enabled 0 } and ${ICINGA_BASE}/etc/objects/commands.cfg contains: define command { command_name check_icinga_startup_delay command_line $USER1$/check_dummy 0 "Icinga started with $$(($EVENTSTARTTIME$-$PROCESSSTARTTIME$)) seconds delay | delay=$$(($EVENTSTARTTIME$-$PROCESSSTARTTIME$))" } both of these files had not been modified since the whole make/install process. I am running on Ubuntu 10.04, most recent build of icinga-core, and apache2 2.2.14 What must I do to tell Icinga that the command exists? Or is the problem that check_dummy does not exist? Where or how would I define that?

• Suggestions for programming language and database for a high end database querying system (>50 milli

  - by mmdave

  These requirements are sketchy at the moment, but will appreciate any insights. We are exploring what would be required to build a system that can handle 50 database million queries a day - specifiically from the programming language and database choice Its not a typical website, but an API / database accessing through the internet. Speed is critical. The application will primarily receive these inputs (about a few kb each) and will have to address each of them via the database lookup. Only a few kb will be returned. The server will be run over https/ssl.

• Locate rogue DHCP server

  - by Farseeker

  I know this is a serious long shot, but here we go. In the past week or so, for users connected to a particular switch in our network (there are four dumb switches all connected, and it only affects SOME, not all, users on the one switch) are getting DHCP addresses from a rogue DHCP server. I have physically checked every cable plugged into the switch in question to make sure that none of them have a router or wifi point attached to it. I know the IP of the DHCP server, but I cannot ping it, and it does not have a web interface. Does anyone have any suggestions on what I can do to locate it or shut it down? Unfortuantely all the switches are unmanaged, and as mentioned, there's no physical device (that I can find) plugged in to anything. It's getting critical, because it's screwing up the PXE boot of a whole bunch of thin clients.

• I cannot format my PC

  - by Jesus Buelna

  I have a Toshiba Satellite(1) l505 6gb RAM, 6.00GB hard disk.Initially I have problem with another satellite(2) I had (mother board problem). I took my Laptop to a technician and cost a lot of money (almost as much as buying new one). So, since I have HDD problems with the first one(1) I decided to use the hard disk of the other one(2). I formatted the HDD and erased the partitions it had into 1 partition (or no partition). The problem is that when I try to format with the SO CD, in the screen, where I have to decide in which partition I want to install the SO, the only one option I have says "unallocated partition and I receive this message "Windows cannot install the SO in this partition, run files do not existed or maybe corrupted" When I erased the disk with Parted Magic, Did I erased any files needed for running the installing disk? I don't know. Is it possible to fixed or reinstate the disk to install the OS? By the way, I checked the disk physical health with Parted Magic, and it is OK. One more thing when I erased the disc to 0, I used the safety option offered by the Parted Magic.Need help please.

• Torrents: Can I protect my software by sending wrong bytes?

  - by martijn-courteaux

  Hi, It's a topic that everyone interests. How can I protect my software against stealing, hacking, reverse engineering? I was thinking: Do my best to protect the program for reverse engineering. Then people will crack it and seed it with torrents. Then I download my own cracked software with a torrent with my own torrent-software. My own torrent-software has then to seed incorrect data (bytes). Of course it has to seed critical bytes. So people who want to steal my software download my wrong bytes. Just that bytes that are important to startup, saving and loading data, etc... So if the stealer download from me (and seed it later) can't do anything with it, because it is broken. Is this idea relevant? Maybe, good torrent-clients check hashes from more peers to check if the packages (containing my broken bytes) I want to seed are correct or not? Thanks

• Server Configuration / Important Parameter for 500Req/Second

  - by Sparsh Gupta

  I am configuring a server to be used as nginx server for a very heavy traffic website. It is expected to receive traffic from a large number of IP addresses simultaneously. It is expected to get 500Req/Second with atleast 20Million unique IPs connecting it. One of the problems I noticed in my previos server was related to iptables / ipconntrack. I am not aware of this behaviour and would be glad to know which all parameters of a ubuntu / debian (32/64) bit machine should I tweek to get maximum performance from the server. I can put in a lot of RAM on the server but mission critical task is the response times. We ideally dont want any connection to be hanging / timing out / waiting and want as low as possible overall response times. P.S. We are also looking for a kick ass freelancer system admin who can help us figuring / setting this all up. Reach me incase you have some spare time and interested in working on some very heavy traffic website servers.

• Pinnacle Studio 14 Importer crashes on Windows 7 x64

  - by Tuminoid

  Pinnacle Studio 14 Importer crashes on Windows 7 x64, thus I'm unable to import videos from my camcorder. I've Googled around and it seems to be a problem with x64 support in the program, but there is no info if it can somehow be remedied with Compatibility settings, XP mode. Further Googling got me this link, and none of the tips in site it links help. I've got no idea what ObjectDoct Plus 2 is (no a program or service installed by that name) which he claims causes the problem. Is that ObjectDoct critical to Pinnacle Studio and how to get rid of it (or any other advice how to make Studio 14 work on x64). UPDATE: 1) XP mode doesn't help as it doesn't handle Firewire, which is how my Canon HV20 must be connected to transfer HDV from tape. 2) I don't have that ObjectDock installed. 3) I don't wanna re-buy PS15 just to get this solved as PS14 should be able to do it.

• How can I get data off of a Corsair SSD?

  - by user1870398

  My Corsair SSD won't work and I have some critical data on it that I didn't back up (I needed to create a copy of my mechanical storage device, just forgot). The drive isn't detected by the OS or BIOS. I also tried it on another system, but all that happened was the OS failed to load (my guess was that it knew the drive was there, just couldn't read it). I tried powering it on without the data cable for a bit of time to see if it'd work again, but it didn't. Any ideas of how I can get the data off of this drive without having to send it in?

• Could we build a mega-processor out of superconductors?

  - by Carson Myers

  A superconductor, once cooled below a critical temperature, loses all of its electrical resistance and therefore becomes 100% efficient. This means that when a current flows through a superconductor, none of the energy is lost to heat or light. Theoretically, could we build a processor out of superconductive materials, that could effectively run at, oh I don't know, say, 300ghz? or 5,000ghz? Since a superconductive circuit is 100% efficient, this means that once supplied with electricity, the source of power could be completely removed from the circuit and the current would continue to flow forever. So if we made all the components inside a computer out of superconductive materials, could we get away with only supplying power to the peripherals and save a-whole-lot on energy, while dramatically increasing computing speed? Might this be one of the next big breakthroughs in computing? What do you think?

• DRS: Unknown JNLP Location

  - by Joe

  We are using Deployment Rule Sets to limit access to the older JRE to well-known applications like - but are running into a problem. One business critical applications has the following properties (*s to protect info): title: Enterprise Services Repository location: null jar location: http://app.*.com:52400/rep/repository/*.jar jar version: null isArtifact: true The application downloads a .jnlp file, and uses java web start to execute. Since the location is null, this application cannot be targeted by a location rule. And the certificate hash method only works when the application is cached (being ran more than once). If cache storing is off, which is the case in some situations, how can this application be targeted? Or at least told to run with an older JRE on start? This problem is specifically noted in this bug Thanks!

• Cron Tips for not running cron jobs on holidays (the monday of a three day weekend)

  - by Poul

  We have about a one hundred machine set-up with each machine running cron jobs like starting and stopping services and archiving these services' log files at the end of the day to a centralized repository. One headache we have is the three-day weekend (we're closed on holidays). We don't want the services starting up on those days and connecting to our business partner's machines. We currently do this by manually commenting out the most critical jobs and letting a bunch of errors happen all day. Not ideal. Basically if a job has '1-5' set in the day field we want this to mean 'work days' and not Monday to Friday'. We have a database that keeps track of which days are indeed 'work days' So, is it possible to override Cron's day-matching algorithm, or is there some other way to easily set a cron setting to avoid things starting up on a Monday holiday? Thanks!

• Linux Port 80 to redirect to a Windows box

  - by Richard Staehler

  I have 2 servers here at work. One is a Windows 2008 Server R2 (for safety's sake, lets use 192.168.1.100) and the other is a Fedora 14 (192.168.1.101). Currently when you hit our subdomain, x.test.com, our routers tell it to go to our Fedora box, and since Apache is installed and listening to port 80, it displays the Fedora Apache Test Page. It's obvious that I don't use port 80 for this machine, however I do use NAGIOS on it and its always nice to be able to access that from anywhere in the world. So when I want to access it, I just type x.test.com/nagios. Now here comes the dilemma.... On the Windows R2 box, we recently have installed a program that requires us to setup a web server using IIS7. Because of this application, I'm going to be creating a new subdomain called y.test.com, but since we only have 1 WAN/router, it will still get pointed to our Fedora box. That being said, it wants to use port 80 as well (or whatever port I damn well wish to assign it). So my question is: since our router is pointing to the Fedora 14 box (.101), and I want to make sure I can access NAGIOS from anywhere in the world, how do I tell Apache (httpd) to redirect port 80 to the other server (.100)? If not possible, what are my other options? I have rinetd installed on Fedora and have even tried the option 192.168.1.101 80 192.168.1.100 80 and it didn't seem to work "because port 80 was already bound" Thoughts? and Thanks!

• check_mk IPMI PCM sensor reading randomly fails

  - by Julian Kessel

  I use check_mk_agent for monitoring a server with IPMI and the freeipmi-tools installed. As far as I can see, the monitoring randomly detects no value returned by the IPMI Sensor "Temperature_PCH_Temp". That's a problem since it results in a CRITICAL state triggering a notification. The interruption lasts only over one check, the following is always OK. The temperature is in no edge area and neither the readings before the fail nor after show a Temp that is tending to overrun a treshold. Has someone an idea on what could be the reason for this behaviour and how prevent it?

• How to control admission policy in vmware HA?

  - by John

  Simple question, I have 3 hosts running 4.1 Essentials Plus with vmware HA. I tried to create several virtual machines that filled 90% of each server's memory capacity. I know that vmware has really sophisticated memory management within virtual machines, but I do not understand how the vCenter can allow me even to power on the virtual machines that exceed the critical memory level, when the host failover can be still handled. Is it due to the fact that virtual machines does not use the memory, so that it is still considered as free, so virtual machines can be powered on ? But what would happen if all VMs would be really using the RAM before the host failure - they could not be migrated to other hosts after the failure. The default behaviour in XenServer is that, it automatically calculates the maximum memory level that can be used within the cluster so that the host failure is still protected. Vmware does the same thing ? The admission policy is enabled. Vmware HA enabled.

• Windows 7 PC crashes after being locked a few minutes

  - by White Island

  I have a problem with an Optiplex 755 PC running (32-bit) Windows 7 Professional. I just installed the operating system last week, and ever since, it seems to crash when I lock the screen. It doesn't happen immediately; it's usually after I walk away, so a few minutes (but I'm not sure exactly how many). I have this non-specific error in the Event log. I've run a chkdsk, thinking it might be hard drive-related, but that didn't help. Any ideas on what to check and how are appreciated. :) Log Name: System Source: Microsoft-Windows-Kernel-Power Date: 11/17/2010 3:09:28 PM Event ID: 41 Task Category: (63) Level: Critical Keywords: (2) User: SYSTEM Computer: WORKSTATION.domain.local Description: The system has rebooted without cleanly shutting down first.

• How to install two packages that write the same file

  - by Joel E Salas

  Sirs, a conundrum. I have two packages that each create /usr/bin/ffprobe. One of them is ffmpeg from the Deb Multimedia repository, while the other is ffmbc 0.7-rc5 built from source. The hand-rolled one is business-critical, and we used to just install it from source wherever it was necessary. I can only assume it would clobber the ffmpeg file, and there were never any ill effects. In theory, it should be acceptable for our ffmbc package to overwrite the file from the ffmpeg package. Is there any easy way to reconcile this?
