  • Making Sense of DNS

    <b>Begin Linux:</b> "Domain Name Service (DNS) was created in 1983 out of the necessity to convert IP Addresses like 192.168.9.2 to domain names like example.com. DNS is a distributed database, what this means is that no one computer is used to maintain a complete database of all of the domains on the Internet. Instead this information is distributed across many computers."

  • Conditional checks against a list

    - by AnnaSexyChick
    I was wondering how computers do this. The most logical way I can think is that they are iterating trough all elements of the list until they find one that matches the condition :) For example if you call function_exists(), PHP should iterate trough all defined functions until it meets the one that matches the name you're looking for. Is this true that this is the only way? If it is, it sounds like it's not very efficient :s

  • WMI permissions: Select CommandLine, ProcessId FROM Win32_Process returns no data for CommandLine

    - by user57935
    Hi all, I am gathering performance data via WMI and would like to avoid having to use an account in the Administrators group for this purpose. The target machine is running Windows Server 2003 with the latest SP/updates. I've done what I believe to be the appropriate configuration to allow our user access to WMI (similar to what is described here: http://msdn.microsoft.com/en-us/library/aa393266.aspx). Here are the specific steps that were followed: Open Administrative Tools - Computer Management: Under Computer Management (Local) Expand Services and Applications, right click WMI Control and select properties. In the Security tab, expand Root, highlight CIMV2, click Security (near bottom of window); add Performance Monitor Users and enable the options : Enable Account and Remote Enable. ­Open Administrative Tools - Component Services: Under Console Root go to Component Services- Computers - Right click My Computer and select properties, select the COM security tab, in “Access Permissions” click "Edit Default" select(or add then select) “Performance Monitor Users” group and allow local access and remote access and click ok. In “Launch and Activation Permissions” click “Edit Default” select(or add then select) “Performance Monitor Users” group and allow Local and Remote Launch and Activation Permissions. ­Open Administrative Tools - Component Services: Under Console Root go to Component Services- Computers - My Computer - DCOM Config - highlight “Windows Management and Instrumentation” right click and select properties, Select the Security tab, Under “Launch and Activation Permissions” select Customize, then click edit, add the “Performance Users Group” and allow local and remote Remote Launch and Remote Activation privileges. I am able to connect remotely via WMI Explorer but when I perform this query: Select CommandLine, ProcessId FROM Win32_Process I get a valid result but every row has an empty CommandLine. If I add the user to the Administrators group and re-run the query, the CommandLine column contains the expected data. It seems there is a permission I am missing somewhere but I am not having much luck tracking it down. Many thanks in advance.

  • Have I bricked my Sun V20z?

    - by David Mackintosh
    I have a small pile of Sun V20z computers. I was trying to update the SP and BIOS firmwares in order to bring them all up to the same standard -- mostly to get the updated (ie actually useful) SP functionality, and figured that I would just do the BIOS while I was at it. For three of the four computers, it worked perfectly. However after the BIOS update, the fourth system won't boot. I did this: batch05-mgmt $ sp get mounts Local Remote /mnt 10.16.0.8:/export/v20z batch05-mgmt $ platform set os state update-bios /mnt/sw_images/platform/firmware/bios/V1.35.3.2/bios.sp This command may take several minutes. Please be patient. Bios started Bios Flash Transmit Started Bios Flash Transmit Complete Bios Flash update Progress: 7 Bios Flash update Progress: 6 Bios Flash update Progress: 5 Bios Flash update Progress: 4 Bios Flash update Progress: 3 Bios Flash update Progress: 2 Bios Flash update Progress: 1 Bios Flash update complete batch05-mgmt $ platform set power state on This command may take several minutes. Please be patient. After an hour of waiting, it still won't start. The chassis powers on, but beyond the fans spinning up and the hardware POST of the drives, nothing appears to happen. So if I try to re-flash the BIOS (on the theory that maybe something went wrong): batch05-mgmt $ platform set os state update-bios /mnt/sw_images/platform/firmware/bios/V1.35.3.2/bios.sp This command may take several minutes. Please be patient. Bios started Error. The operation timed out. Have I bricked it?

  • Can I change the file system on the OS partition on Server 2008 R2?

    - by KCotreau
    I have a client using R1Soft Continuous Data Protection backup, and two of the Server 2008 R2 boxes were erroring out with these errors: Unable to obtain NTFS volume data for device '\\?\Volume{f612849e-7125-11e0-8772-806e6f6e6963}': Incorrect function. Unable to discover information for filesytem volume '\\?\Volume{f612849e-7125-11e0-8772-806e6f6e6963}'; Unable to obtain NTFS volume So I backed up all the registry entries with this, {f612849e-7125-11e0-8772-806e6f6e6963}, in it, and deleted them based on some VERY sparse info from R1Soft. I then decided to restore them before I rebooted, and do a system state backup first using MS backup, and even it errored out saying that there were FAT32 partitions. This was a major clue as the only two computers with problems had these FAT32 partitions. I figured if MS backup can't backup something, any other program is likely to have problems. Also, now that I realized the servers had FAT32 partitions on them, the error referencing NTFS takes on more weight. The partitions on both servers have the label "OS", but on one of the computers, it is given a letter, but on the other not. So I am thinking if I just convert the file systems from FAT32 to NTFS, it may solve the backup problem. So the question is this: Can I just convert those partitions, and does anyone have any concrete knowledge of any major downsides, like the servers not coming back up (of course, I would do one at a time)? My thinking is that the answer is probably at least 95% no, but they are production servers, so I wanted to get some second opinions.

  • SQL 2008 SP2 RsClientPrint ActiveX - "Unable to load client print control"

    - by Miles
    We recently updated our SQL 2008 server to use SP 2 and its causing a few headaches. We use SSRS on this server and when a client tries to print a report by the built-in print function, we're needing to download the RsClientPrint ActiveX control from the server from the client gets the following error Unable to load client print control. We have about 700 computers that are needing this fixed and I've followed the instructions found on the following URL: http://www.kodyaz.com/articles/client-side-printing-silent-deployment-of-rsclientPrint.aspx We have two issues: Most of the users who will be using this ActiveX control are not local administrators so they will not be able to install the control themselves Since there are so many computers, this has to be done silently behind the scenes run by a local admin account After following the information from the link above, we're able to put the files in the C:\Windows\System32 folder and register the DLL but we still get the same problem. The only small thing I've noticed is that in the HTML for the report page, everything that references a version is referencing version 2007.100.4000.00 and the version of the DLL that I pulled from the report server is 2007.100.1600.22. Also, for some clients that are local administrators, they are prompted every time to install the ActiveX control when they click print. This works successfully but we can't have the user asked if they want to install the same control every time they need to print.

  • Ubuntu Server running VNC

    - by xwapilot
    I have access to four computers: 1 Ubuntu Server desktop (Version 10.04) 1 Mac Mini (Snow Leopard) 1 Windows desktop (Windows 7) 1 Windows laptop (Windows Vista) The first three will always be on the home network. My goal is to SSH from the laptop into the server and be able, through VNC (or another remote desktop software), to control the windows and mac computers. The goal of this would be a slightly heightened network security over using VNC to directly access the mac or windows desktop. I have successfully used SSH to connect to the server, but have not been able to successfully implement the remote desktop connection. I would appreciate help doing so. Here's what I've done so far: As per instructions here: http://www.stuartellis.eu/articles/vnc-on-linux/ I installed the following: vnc4server – the main VNC server software vnc-java – enables access from Web browsers with Java support xvnc4viewer – a basic VNC viewer I then set up a password using the vncpasswd command. To attempt to connect to the mac, I followed directions I found in a thread at superuser. com and went to "System PreferencesSharing" and enabled "Screen Sharing". Subsequently, I tried entering the following commands into Ubuntu: vncviewer mac_ip_address::5904 vncviewer mac_ip_address:0 vncviewer mac_ip_address:1 They all returned the following: VNC Viewer Free Edition 4.1.1 for X - built Apr 9 2010 18:41:55 Copyright (C) 2002-2005 RealVNC Ltd. See http ://www .realvnc. com for information on VNC. vncviewer: unable to open display "" I'm sure I'm missing something important, but I'm not sure what it is. Do I need to have a GUI installed, or did that come with the vnc packages I installed?

  • Why did MAC-Adress Cloning Fix My Router?

    - by FranticPedantic
    I have a Belkin router, and about a year ago, I suddenly lost my internet connectivity from Comcast. The internet worked fine when I plugged it right into my laptop, so I just ignored it. When I moved to another apartmnet I eventually took the dive and called tech support. The tech told me to clone my MAC address which completely fixed the issue. Now I know what a MAC address is and I've read what MAC cloning is. What has bothered me since is that I don't see how this fixed the issue. As I have understood MAC address cloning, it has the router pretend it has the same MAC address as my computer. Here is why I don't understand why this fixes my issue: I have used several different computers with this router. Cloning the MAC address fixed it for ALL of my computers. The laptop I first used with my ISP was not the one that I eventually had connected when I cloned the address. Furthermore, I didn't have any problems for quite some time after I stopped using the first computer. It wasn't like the internet suddenly stopped working when I changed which laptop I was using Now it occurred to me that maybe there was some sort of expiration? Except... Which MAC address did it clone? It was just an option in the router administration page. Did it just pick whichever computer was connected to it? If my ISP still wanted the MAC of my first computer, how did some other computer's fix it? As mentioned earlier, why did this problem seemingly stem from nowhere? Anyway, I don't have any current problems so this is more just out of general curiosity. If anybody can explain it, it would be appreciated!

  • Wifi Drops Connections with WPA2-PSK

    - by graf_ignotiev
    I run a small computer lab made up of 10 computers of identical hardware and software (Dell Latitudes with Windows 7 x64 Enterprise) and I use a ZyWALL 2WG as a router/firewall. Nine of the computers connect to the router over wifi using WPA2-PSK encryption while the last one is connected by ethernet cable. I'm having a problem where any computer connected to the wi-fi occasionally drops off the network (it cannot be pinged and the client cannot ping the gateway). It only happens on the wifi side and only when the encryption is WPA2-PSK or WPA-PSK. I tried using another router with a different make and model and had no problems. Thinking it could be a software error, I reset the router to factory defaults and installed the newest firmware (V4.04(AQI.8) | 04/09/2010), but still have the problem. The 802.1X log gives the following error User logout because of user disassociation. with this note WPA2-PSK:00242c582ece:logout where 00242c582ece is the mac address of the device. At this point I'm out of things to try and leads to follow. It looks like this user had the same or similar problem, but none of those proposed solutions work for me.
