• Getting around the lack of GPT support with CentOS 5.4

  - by sxanness

  Here is my issue and I hoping that there is someone out there that has an answer so I don't end up stuck here at my co-location all day. Last night I came here and upgraded a server (Dell 2970) to have four 1TB Hard Drives in RAID 5 which leaves a 3TB block. I tried to partition this but keep getting an error that GPT is not supported so I found a site online telling me I need to run the dd command and right random data to /dev/sda. This is great (if it works) but taking forever. I have two more machines to upgrade today and not a chair in site. Does anyone have advice on how I can avoid this issue beforehand? Thank You for your advice and support.

• Remapping Home/End from PC to Mac Via Synergy is not client specific.

  - by DtBeloBrown

  This question asks about the end key but the answers give no examples: http://superuser.com/questions/60052/what-key-works-like-end-using-a-mac-with-synergy If they had, I am guessing that they would likely have run into this problem. Adding lines like the bottom two of this: section: options keystroke(End) = keystroke(Control+Right,myiMac) keystroke(Home) = keystroke(Control+Left,myiMac) to my synergy.sgc in MyDocuments on the winXP machine would work but causes the keys to stop functioning on the winXP machine. Unacceptable. I next tried a compromise: keystroke(End) = keystroke(Control+Right,myiMac); keystroke(End,myPc) keystroke(Home) = keystroke(Control+Left,myiMac); keystroke(Home,myPc) Expecting that to broadcast the keystrokes to both machines regardless of which one was the Active Screen. That and many other variations did not work. What am I doing wrong? Has someone actually done this?

• setting up multi-mon windows + mac

  - by psychotik

  Ok this is a stretch, but I know of some Windows only software that does this so curious if there is something that does it on the mac too. I have 2 monitors and 2 development machines - a PC and a Mac Mini. I want to be able to view/control both concurrently (one on each monitor). The Mac only has DVI out, the PC has both and my monitors have both. Any suggestions on how I can do it? A solution involving KVM or software (VNC/remoting) is OK... Thanks!

• How to prevent Ubuntu from combining networks on 2 NIC server?

  - by SolarPower

  I've got a Ubuntu Server 10.10 with 2 network interfaces with a cable plugged into both going to switches on completely different networks with different routers. One network is the 10.1.10.X network with a separate gateway/router - the server has an IP of 10.1.10.50 with the gateway IP of 10.1.10.1. The other interface is 10.2.10.X, IP 10.2.10.50, gateway 10.2.10.1. All my Mac machines are on the 10.2.10.X network, and all servers on the 10.1.10.X. The ONLY connection between the two is this machine. From a Mac in my office, I CANNOT ping any computer on the 10.1.10.X network except the Ubuntu machine I'm talking about. However, under the Shared column in Finder, I can see every server on the other network listed. That makes me believe that somehow this Ubuntu machine is letting certain requests span both networks, which is a security problem. Hope this is enough info.

• What response should be made to a continued web-app crack attempt?

  - by Tchalvak

  I've issues with a continuous, concerted cracking attempt on a website (coded in php). The main problem is sql-injection attempts, running on a Debian server. A secondary effect of the problem is being spidered or repeatedly spammed with urls that, though a security hole has been closed, are still obviously related attempts to crack the site, and continue to add load to the site, and thus should be blocked. So what measures can I take to: A: Block known intruders/known attack machines (notably making themselves anonymous via botnet or relaying servers) to prevent their repeated, continuous, timed access from affecting the load of the site, and B: report & respond to the attack (I'm aware that the reporting to law enforcement is almost certainly futile, as may be reporting to the ip/machine where the attacks are originating, but other responses to take would be welcome).

• Oracle EE 11.2g: how to generate fresh new redo logs

  - by Aikanaro

  Hi, In the company I work for we are heavy users of vmware machines. Almost all our projects are developed inside a virtual environment up to the point where we have to deploy them into a production system. While in development, some colleagues of mine deleted the redo log files for Oracle in the hopes of gaining some free space. Now they are unable to start the database instance. Is there a way of generating a fresh new redo log so that the instance can be started? This is urgent and even though I'm currently googling for an answer I have yet to find it. Thanks in advance.

• Using Windows 7 drivers in Windows Server 2008 R2

  - by Robert Koritnik

  Maybe I should post this to http://www.serverfault.com. Windows 7 comes with all sorts of signed drivers so there's high probability that all drivers for your machine will be installed during system setup. On the other hand Windows Server 2008 doesn't event though it's practically the same OS when it comes to drivers. But I know that this has a very good reason. It's a server product, not a desktop one. But the thing is that many power users and developers use server OS on their workstations which are normally desktop machines and would need Windows 7 driver spectrum... Question I know I've been reading about some trick on the internet that first installed Windows 7 on the machine, than do something to get either all Windows 7 driver collection or just those installed, and then install Windows Server 2008 and use those drivers. The thing is: I can't seem to find these instructions on the internet any more. If anybody knows where these are please provide the link for the rest of us.

• Mac Joining Active Directory Still Prompts For Authentication

  - by David Potter

  My Mac is joined to an Active Directory domain. What I expected to see was the same ease of access to file shares and internal websites that Windows computers joined to the domain experience (i.e., no authentication needed; it just uses Windows Integrated Authentication). Instead I am asked for credentials each time I try to access those shares and protected websites (e.g. SharePoint). Is this normal behavior, or is something wrong with my Mac that it prompts me for my username and password for the domain when I access Windows file shares or intranet sites protected by NTLM/Kerberos? Machines include: MacBook Pros running Mountain Lion MacBook Pros running Lion MacServer running Lion Server

• Macbook Pro 2.66 GHz vs. 2.8 GHz

  - by nevan

  Is there much advantage in getting the higher end Macbook Pro compared to the mid-range one? The differences between the two are: 2.66 GHz vs. 2.8 GHz 256 MB graphics memory vs. 512 MB 3 MB L2 cache vs. 6 MB 320 GB hard drive vs. 500 GB $2000 vs. $2300 I've looked around, but I can't find any direct comparisons for the two machines. I'd be using the machine for development. I generally use a computer for 3 years. I don't really play games, but do use Photoshop regularly. I've heard that once Snow Leopard arrives, the graphics chip will be used to boost the main processor, so I was wondering if getting the one with more graphics memory would be an advantage?

• Network / Internet diagnostic tool to locate an error?

  - by Jesper

  Hi, I’m facing some difficulties with the Internet / network at my work and I have trouble locating the precise error and when and how it occurs. The problem is that the client machines in the house sporadic is disconnected to the Internet. I’m some what new so I haven’t that much inside in the network and apparently neither has my predecessor. What I am requesting and hoping you guys knows about is, if there exist some kind of network monitor tool I can install and run and it will periodically check the network, the Internet connection etc. and record to logs. Then, if there suddenly arises a problem some time of the day in some part of the network or the Internet connection, I can check it perhaps the next day. I’ve just downloaded and installed Microsoft Network Monitor 3.3 application and hopeful it can give me some answers on where the instability is located but I still would like a tool to make different checks and test in some time interval. Do anyone know about such a program or another kind of performance / diagnostic tool / method I can use? Sincere Jesper

• Handling range in CNAME

  - by Imran

  We have different set of CNAMEs pointing to different subdomains. These subdomains (a.domain.com, b.domain.com) are pointing to different IPs on different machines. # Server A a1.domain.com pointing to a.domain.com a2.domain.com pointing to a.domain.com .. aN.domain.com pointing to a.domain.com # Server B b1.domain.com pointing to b.domain.com b2.domain.com pointing to b.domain.com .. bN.domain.com pointing to b.domain.com Currently, we have to add individual CNAME entries (eg. a1... aN) against a single subdomain (a.dominan.com). We repeat the above process for every new server which is actually another subdomain (e.g. c.domain.com). Is there a way we can specify a range of CNAMEs (e.g. [a1..a25].domain.com point to a.domain.com) instead of adding separate CNAME etnries? Is there any possibility to handle this at DNS or webserver (apache or Nginx) level?

• How to make HOME or END keys work in mc running on OS X (ssh)

  - by Sorin Sbarnea

  I installed MacPorts on OS X 10.5 and I found out that when I connect to the computer using SSH and use mc - Midnight Commander - the HOME and END keys do not work. I have to mention that I'm using putty and I am able to use the keyboard very well on Linux machines like Fedora, Ubuntu,... Here is putty keyboard configuration (a configuration I found to be optimal over time): Backspace key: 127 Home/End keys: Standard Function keys: Xterm R6 Cursor keys: Normal Numpad: normal Terminal type string: xterm-color I'm looking for a command line solution/script that does these changes, this make much easier to create a prepare OS script for configuring a new OS.

• How to get Windows 7 to automatically connect to an ad-hoc network?

  - by George Edison

  I have two machines - one is running Ubuntu 12.04 64-bit and the other is running Windows 7 Starter Edition (32-bit). The Ubuntu machine is connected to the Internet via the eth0 interface. That machine also has a wireless network interface (wlan0) that is currently functioning as an ad-hoc network. I can connect to the ad-hoc network just fine with the Windows machine but each time I wish to do so, I must manually initiate the connection and enter the password. Is there some way to instruct Windows to automatically connect to this network (an option I have for standard wireless networks but not ad-hoc networks)?

• How do I resolve active directory connection errors when using dcpromo?

  - by Middletone

  When attempting to promote a secondary server to an existing active directory forest I receive the following error message and can no longer continue. Failed to examine the active directory forest. Value ridMasterDSA.partentDN not found What can cause this and what can be done to fix it? Both servers are 2008 running on x64 and can see each other on the network via their names. FYI: The firewall is turned off on both machines so there should be no issue there. Also the server that i'm adding is already a part of the domain. One server is already a domain controller but I want to add a second to it.

• Task bar remains visible with "Auto-hide the task bar" checked in Windows 7.

  - by Corey

  It's about time that I figure this out. I can say with a pretty high confidence that I have experienced this issue in all consumer versions of Windows since XP. I keep "Auto-hide the task bar" checked to maximize screen real estate. Every once in a while, the task bar will refuse to hide while individual windows will continue to act as if that option is checked (by falling under the task bar). For years, I have fixed this by rebooting. Of course, I cannot predict the timing or frequency of the problem, so the process becomes burdensome. I want to know how this can be fixed without rebooting. It has affected my on multiple machines using multiple versions of Windows, so I cannot be the only one who is bothered by it. Can anyone help me solve this?

• Problem with Windows activation on a VM (Virtual machine)

  - by Daisetsu

  I backed up a number of laptops to virtual machines before they are to be re-purposed, in case I need the data at some later time. While the Physical to VM processes worked fine I am encountering issues on some of the VMs. When I boot them I get an error message saying I MUST activate windows in order to login. This is expected because the hardware changed (from physical hardware to virtualized hardware). I click the OK button and expect to be prompted with ways to activate, windows sits there for quite a while then tells me that "Windows has already been activated". I click OK at that message and get take back to the beginning where I am asked to activate Windows. I have done some fairly intensive googling but haven't been able to find a real solution. EDIT: The laptops with the issues are 2 Sony Vaios, I believe that they have the OEM version of the OS originally installed by the factory.

• Linksys WRT54Gx as Repeater Bridge

  - by Robert Koritnik

  I have a Linksys WRT54Gx router with DD-WRT software working fine. But. Is it possible to use it as a Repeater Bridge when the host router isn't configured to be in the default 192.168.1.1 subnet? I've set everything from these instructions. I've also tried setting repeater router's IP address to be inside host's subnet, setting Gateway + DNS IP addresses... But It still didn't work. Client machines connecting to second router (my Linksys) were configured to use DHCP and also static IPs within host's subnet. Nothing worked. Can anyone tell me how to configure it to make it work?

• Web based console connections not working in Windows 7 posted: Jan 20, 2010 8:55 AM

  - by nmeth

  For slightly complicated reasons we tend to give people console access to VMs via the webui. This has worked fine in the past, however when the users update their client machines to Windows 7 (or Vista, I am told, although I have not tested that), then the console fails to work. On IE8, having allowed the ActiveX control, the tab causes a "Internet Explorer has stopped working" dialog. On Firefox 3.5 , once the plugin has been installed, using the console causes the browser to crash. I've updated to the most recent VC 2.5 release, and ESX 3.5u5. Anyone else seeing this? Any clues how to get round it (other than using the fat client). Nigel.

• VirtualBox - split partitioned VDI into separate VDIs

  - by mathematical.coffee

  I'm very new to VirtualBox. I set up an Arch Linux VM and a Ubuntu VM (Ubuntu host), both sharing the same .vdi like so (I had in my mind a dual-boot situation): VDI file (25GB) |- /dev/sda1: 5GB (Arch Linux) |- /dev/sda2: [Ubuntu] |- /dev/sda5 (swap, 1GB) |- /dev/sda6 Ubuntu /, 9GB |- /dev/sda7 Ubuntu /home, 10GB I've now realised that I don't want a dual-boot-type setup, I'd rather boot each machine independently (my initial thought was to share /home between Ubunto and Arch). So, my question: Can I split /dev/sda1 and /dev/sda2 each to their own .vdi files so I can use them as completely separate machines? I'd rather not have to re-install either Arch (because it took me ages to work it out!) or Ubuntu (because I've already done a few GB of updates and don't want to redo them). I haven't been able to find anything about this - most questions I see are about converting a .vdi to a partition on the host, or splitting a .vdi into multiple smaller files (that are not independent), or converting a partition on the host to a .vdi file. cheers.

• Automate Windows 8.1 Enterprise upgrade

  - by Ben M.

  I have been trying to find the necessary command line switches for automating the upgrade for my Windows 8 clients to Windows 8.1. I have the ISO extracted and I've run setup.exe /? but that doesn't tell me enough. I can't find any relevant information from search engines. Can anyone point me to some documentation or information on how to automate the upgrade so that it keeps user data, programs, etc? I know how to do it when running the installer manually, but I obviously do not wish to do that with 100+ machines.

• Performance difference between MacBook Pro (2.8 GHz) vs Air (1.7 GHz)?

  - by jonathanconway

  I'm comparing these two Apple laptops: MacBook Pro (13", 2011 model): 2.8GHz dual-core Intel Core i7 processor with 4MB shared L3 cache 4GB (two 2GB SO-DIMMs) of 1333MHz DDR3 SDRAM AMD Radeon HD 6770M graphics processor with 1GB of GDDR5 memory on 2.4GHz configuration MacBook Air (13", 2011 model): 1.7GHz dual-core Intel Core i5 with 3MB shared L3 cache 4GB of 1333MHz DDR3 onboard memory Intel HD Graphics 3000 processor with 384MB of DDR3 SDRAM shared with main memory There's definitely a gap between them in terms of CPU speed and graphics, but what practical difference would this make on a day-to-day basis? On the one hand, I love the sleek, thin appearance of the Air. On the other hand, I don't want a machine that's going to be dog-slow when doing tasks such as running Virtual Machines, dual-booting to Windows and running multiple instances of Visual Studio, and maybe some light gaming. Is there going to be a major difference that makes the MacBook Pro a more attractive purchase?

• Connecting Small business network to Azure Site to Site VPN

  - by MarkKGreenway

  Would like to have connectivity between azure virtual machines and on LAN users. My current network has a Cisco ISA550 connected to the WAN (one Ethernet cable into the office the fiber transceiver is on a different floor)and any public servers can be one-to one NAT-ed to have a public and private IP. What is the best way to get a reliable connection. Between end users and the cloud? I want to know the preferred on site endpoint. Do the azure vm's have to have a local ip in the LAN subnet? (Right now 10.10.0.0/20 or 255.255.240.0 to give room if this is the case). If in purchased an asa550 would I put it behind or in front of the isa550. Would it be ahead or peer with the users switches? What is the best way to get a reliable connection. Between end users and the cloud servers?

• Microsoft IME + Japanese: Force Hiragana input by default?

  - by Mica

  I am using Windows XP SP3 and Windows 7. On both machines, I cannot make Hiragana the default input method. Is there a way to do this? In the IME tool bar, there is the option to set the "Input Mode." This is always defaulted to "Direct Input." I would like to default to Hirgana or Katakana. I have found the setting dialog for this, by right clicking on the IME toolbar - settings - Japanese IME Standard - Properties - Default Input Mode. This setting seems to have no effect, no matter the combination of selections in the dialogs. Is there a way to reliably set the default Input Mode?

• On setting up Apache and IIS to share the same IP

  - by miCRoSCoPiCeaRthLinG

  Hello, There are two different web-apps running on two (physically) different servers on our network... one of IIS and another one on Apache - both on port 80 since two machines are accessible by different IPs on our internal network. Now I want to expose both these services to the world. My idea is to somehow make the incoming connection redirect to the appropriate server based on user's choice of subdomain. Example xxx.domain.com maps to the IIS (Internal IP: 1.2.3.4) yyy.domain.com maps to Apache (Internal IP: 5.6.7.8) To the world, both these servers will share the same public IP. What kind of a configuration am I looking at and how do I go about trapping the subdomain requests and redirecting to the appropriate server? Thanks, m^e

• Is Tomcat Shared Session / Cluster between two machine possible?

  - by Snorri

  I have a setup of several Tomcat servers distributed between a few servers, all running the same thing. Apache is on top of Apache and a loadbalancer in front of the Apache servers. I want to cluster the Tomcats using Shared Session to minimize downtime and user interruption while deploying apps. I know clustering works within the same server but is it possible to setup Tomcat in a way that it shares sessions between servers on different machines? => Server 1 ==> Apache 1 ===> Tomcat 1 => Server 2 ==> Apache 2 ===> Tomcat 2 When Server/Tomcat 1 would be taken down, users and their sessions would transfer over to Server/Tomcat 2 and vice versa.
