• SQL SERVER – FIX ERROR – Cannot connect to . Login failed. The login is from an untrusted domain and cannot be used with Windows authentication. (Microsoft SQL Server, Error: 18452)

  - by pinaldave

  Just a day ago, I was doing small attempting to connect to my local SQL Server using IP 127.0.0.1. The IP is of my local machine and SQL Server is installed on the local box as well. However, whenever I try to connect to the server it gave me following strange error. Cannot connect to 127.0.0.1. Login failed. The login is from an untrusted domain and cannot be used with Windows authentication. (Microsoft SQL Server, Error: 18452) The reason was indeed strange as I was trying to connect from local box to local box and it said my login was from an untrusted domain. As my system is not part of any domain, this was really confusing to me. Another thing was that I have been always able to connect always using 127.0.0.1 to SQL Server and this was a bit strange to me. I started to think what did I change since it  last time I connected to SQL Server. Suddenly I remembered that I had modified my computer’s host file for some other purpose. Solution: I opened my host file and immediately added entry like 127.0.0.1 localhost. Once I added it I was able to reconnect to SQL Server as usual. The location of the host file is C:\Windows\System32\drivers\etc. You will find file with the name hosts in it, make sure to open it with notepad. If you are part of a domain and your organization is using active directory, make sure that your account is added properly to active directory as well have proper security permissions to execute the task.

• Getting "Unable to find a medium containing a live file system" when installing 10.10

  - by Krastin Konstantinov

  I got this error while trying to install ubuntu 10.10 from a bootable USB stick on to Sony Vaio P series laptop. The disk boots into the language and installation type screen. After that it goes through the splash and pulls up this error: BusyBox v1.13.3 (Ubuntu 1:1.13.3-ubuntu11) built in shell (ash) Enter 'help' for a list of built-in commands. (initramfs) Unable to find a medium containing a live file system After getting this error the installation fails to start. I have used the same USB stick on some other laptops and the installation started as usual. Any help will be appreciated. My installation is i386 and my machine is Vaio P VGN-P610. I've tried every possible thing: Bios: [enable boot external] Boot order: [external] [hard drive] [network boot] Tried 2 different USB drives Tried 2 different external CD drives Tried 6 different downloads of both the desktop and netbook remix. All downloads were checked with MD5SUM. Ubuntu Desktop 9.10 installs properly in every version and from every source. Getting reaaaally frustrated.

• Prevent Windows 7 from installing a "critical" updates that crashes the system

  - by Sylverdrag

  I am running Windows 7 home premium. Up until yesterday, everything was going just beautifully, until I received a "critical update". As soon as the critical update was installed, the system became extremely unstable and froze up every few minutes requiring me to restart the system several times, with the same results. I used system restore to roll back the * update, and everything went back to normal... except that I keep getting a message telling me to restart the computer so that it can install this "critical update". There is no "don't install that crap on my machine" option. Disabling the updates doesn't change anything, turning off the windows update service doesn't change anything either, and being on Home premium, I have no access to the group policies. Any ideas of what can be done to prevent Windows from installing this update the next time I reboot?

• Does Windows 7 support multiple simultaneous nVidia graphics cards with different drivers?

  - by mckenzieg1

  On one of my dev machines at work (currently running XP), I have two nVidia graphics cards: Quadro NVS 440 (my original card, for my three primary monitors) GeForce GTX 275 (just added, for CUDA development) I can get both cards to work OK by installing the latest GeForce drivers, but I get some annoying-but-not-crippling display artifacts on the Quadro's screens (mostly scattered black rectanges where repainting fails for a few bits of UI in certain applications). Under XP, this seems to be the best I can do. I can use Device Manager to supposedly install different nVidia drivers for the two cards (the latest Quadro drivers for the NVS, the latest GeForce drivers for the GTX), but I actually end up with the same driver for both, because the driver dlls all have the same names and get installed on top of one another in the system directory. I have read that Win7 has a new video driver architecture that better supports multiple heterogeneous cards. Does anyone know if that will handle my scenario? If so, it will give me a compelling reason to get that machine on Win7 ASAP.

• Emulating CP/M under Linux

  - by gh403

  I need to be able to run a very old piece of software -- the HI-TECH z80 C Compiler for CP/M. It has been released as freeware by HI-TECH. Alas, it only runs on CP/M. After a lot of Googling, I found a page of utilities for UZIX. One of those utilities is a script to abstract away the emulation of a CP/M machine, thus allowing you to use the compiler as you would any other UNIX program. The problem with this script is that it depends on their own CP/M emulator, which unfortunately will not compile on a modern (x64) system. My question: is there a usable CP/M emulator for Linux that could be used in a similar fashion? Specifically, I need to be able to somehow have it access files from the host system, a la DOSBox. I'm willing to rewrite a script (I don't have to re-use the UZIX one); I just need an emulator. Thanks for any help!

• Logging with Resource Monitor?

  - by Jay White

  I am having sudden spikes in disk read activity, which can tie up my system for a few seconds at a time. I would like to figure out the cause of this before I set my machine to go live. With Performance Monitor I know I can log activity, but this does not show me individual processes that cause a spike. Resource Monitor allows me to see processes, but I have no way to keep logs. It seems unless I have Resource Monitor open at the time of a spike, I will not be able to identify the process causing the spike. Can someone suggest a way to log with Resource Monitor, or an alternative tool that can?

• Problems installing icinga-web

  - by Kungurov

  I'm using Ubuntu 10.04 LTS (64bit, Server), Apache 2.2.14 Following the instruction from the oficial icinga page http://docs.icinga.org/latest/en/index.html I installed the icinga-web-1.7.1 on my machine and configured a few hosts for test purposes. The Classic Interface runs as expected but the new Web Interface does not show any data. When I try: ps aux | grep ido2db | grep -v grep I get: icinga 27425 0.0 0.0 41464 600 ? Ss Jul27 0:00 /usr/local/icinga/bin/ido2db -c /usr/local/icinga/etc/ido2db.cfg which might indicate a problem with idomod/ido2db because according to the docs there should be at least 2 processes greped. Any ideas how to fix that?

• Logout trouble with alternative shells (Win7 Home Premium x64)

  - by M. Cain

  I've tried bb4win and Litestep, and every time I need to log out for some reason (shutdown and all included), the system hangs and the spinning icon next to the "Logging out" text stops spinning. Changing the shell in registry for both local machine and current user causes this behavior. Any ideas on what might cause this? Alternatvely, what steps can I take to figure out what is going wrong? In Linux, you are able to open things in a framebuffer and examine the output, but with Windows it is not so clear to me how to see what is happening under the hood, especially with this Home Premuim version. Update: Since logging out normally to switch the shell back to Explorer doesn't work normally, I have to end Litestep first. However, when I do so, an Explorer navigation window pops up (not the taskbar). This also occurs with bb4win.

• Software to cache a web application for use offline

  - by littlecharva

  My boss quite regularly has to demo our web application to clients in a situation with no wifi available and sketchy 3G access, quite often the 3G lets him down. I have considered setting a copy of our server up in a virtual machine on his laptop so he could demo it offline, but I fear this will just introduce more headaches when he forgets how to boot the VM up. What I'd ideally like is an app that records you logging into a web app, saves copies of all the pages and ties the links and buttons you click up to offline copies of the pages it saves. So you could run through the demonstration you're going to give and have it cache the pages. When you then click the same buttons and links in offline mode it will present the relevant offline pages. Does such a thing exist? Can anyone recommend any alternative solutions to this problem? Thanks, Anthony

• Bridging wireless and wired networks on Linux box

  - by nixnotwin

  I have the following setup: modem + router - - - - -Ubuntu box on master mode.........wireless devises. Ubuntu machine connects to Internet on wired network. I've dhcp3-server, masquerading, and wireless card with master mode on Ubuntu box. The issue is Ubuntu connects to the router on NAT. The wireless devises connect to the Ubuntu box on a NAT too (though different). SO my wireless devises are behind two NAT networks. The solution I am looking for is Ubuntu should forward dhcp requests to the modem+router, and Ubuntu should act as a switch or a bridge that allows wireless devises to connect to the wired network. So the modem+router should act a main router.

• Why is my hosts file not working?

  - by elliot100

  I've been using the hosts file to for local website development, and it's recently stopped working. No entries other than localhost resolve. I've simplified to test, so it now contains only 127.0.0.1 localhost ::1 localhost 127.0.0.1 test.dev localhost responds to ping, test.dev does not. The file is called hosts with no extension It has no trailing spaces It's saved in C:\WINDOWS\System32\drivers\etc which matches the value of HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\DataBasePath Oddly, despite UAC being on, I can edit, delete and save the file without admin permissions No proxy is being used, PC is not connected to network for testing Stopping the DNS Client service seemed to resolve the issue for a few minutes, test.dev briefly resolved but doesn't any more. Only firewall is Windows' Machine has been restarted. Is there anything else I should try?

• Forwarding wifi traffic to wired pc

  - by brydgesk

  I'm trying to play around with Wireshark on my home network, and was wondering if there is a way to create a new connection on my PC that receives all wifi packets on the network. The PC is a wired Windows 7 machine, and I'm using DD-WRT on an Asus RT-N16 router. I'm not trying to hack anything, I have full admin access to the router itself. My searching has led me to articles about client bridges and repeater bridges, but none of them seemed to apply entirely to my situation. I'd like to continue using my standard wifi connection, but make my PC act as a repeater that receives all wifi traffic. Again, the PC has no wireless connection. I've used tcpdump which is installed on the router itself, but I'd be more comfortable analyzing the packets in Windows, as I'm trying to learn Wireshark. Thanks

• Would You Swim Laps in Lake Baikal?

  - by rickramsey

  source This is the lake where Yuli Vasiliev's countrymen swim laps. Yuli is one of my favorite OTN writers not just because he really knows his stuff. Not just because his writing is clear and accurate. And not just because his English is better than the English of most native speakers. Yo, those are all good reasons. But it's the Lake Baikal thing. Yuli recently wrote two wicked good how-to's about Oracle VM Templates. You should read them. You might gain a gram of Yuli's respect. Two grams, if you can head butt icebergs while you swim. How to Use Oracle VM Templates How to prepare an Oracle VM environment to use Oracle VM Templates, how to obtain a template, and how to deploy the template to your Oracle VM environment. Also how to create a virtual machine based on that template and how you can clone the template and change the clone's configuration. How to Use Oracle VM VirtualBox Templates How to use Oracle VM VirtualBox Templates in Oracle VM VirtualBox. Similar to the article above, but it describes how to download, install, and configure the templates within Oracle VM VirtualBox, instead of on bare metal.

• How to run multiple distros using lvm

  - by Mark

  I've seen quite a few posts around about running multiple distros but not sure they apply to using LVM (and without Windows). I'm using a machine that's about 3 years old. Setup: Intel Core i7 2.8GHz 8GB Ram 1TB SATA HDD At this point, I'd like to install 12.10 and Mint 14, leaving the option open to install additional distros down the road. I could be way off, but I'm thinking about creating at least 2 primary /boot partitions (1 for 12.10 and 1 for Mint) and another partition for LVM leaving room for additional /boot partitions. Then creating a VG and separate LVs for Ubuntu 12.10 and Linux Mint 14. I understand I can share partitions between the 2 installs, but I'm only using this for testing and I have tons of space to play with. LVM seemed logical considering I may want to install and test additional distros. I guess I could share the /swap partition across the board without problems, right? I'm unclear about GRUB2. How do I handle the bootloader situation? Install 12.10 and get it running then make changes to grub.cfg after installing Mint? And do I not install GRUB for Mint or do I install it in a different location? Any guidance would be appreciated.

• Can I list file names (or their parent directories) that were recently deleted using rm in OS X?

  - by Andrew Grimm

  Is it possible to find out which files and directories have recently been deleted by rm in OS X? Or failing that, is it possible to find which parent directories have had files or directories within it deleted? The OS version is Snow Leopard. Background: Last night, rvm (ruby version manager) did rm -rf of the ~/ruby directory from the home directory. (This bug has since been fixed) Ideally, I'd like to know what files within the ~/ruby directory were deleted, but failing that, I'd like to know if rvm deleted anything outside of ~/ruby . In case anyone's wondering about backups...: Just about everything within ~/ruby is a git project that has a remote repo, and I have a fairly recent Time Machine backup (only 20 days old).

• Temp profile used when User logs in

  - by TJ

  One of my users logged into his computer, Windows XP, last night only to be meet with an error message that it could not load his profile and he will be logged in using a temporary profile. Typically when this happens I shut the machine down and restart and the correct profile will load when they log in again. Not this time. In the user profile options under computer-properties-Advanced-user profiles it show that there are three profiles with his name. Two are the exact same size with the same modified date (5/5/10) and the other is what I would expect size wise for a new profile with a modified date of today. What are my options to restore his profile?

• tmux: unbind C-[ as a prefix

  - by StanAngeloff

  I have a fairly straight forward .tmux.conf file which does nothing more but to define a couple of options, such as history-limit. I have not added any custom key bindings yet. I find it extremely annoying that I cannot unbind C-[ as a prefix in tmux. Here is what I mean: $ uname -a Linux stan-inspiron 3.2.0-24-generic #39-Ubuntu SMP Mon May 21 16:52:17 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux $ tmux [0] 0:~* "stan-inspiron" 10:05 12-Jun-12 % vim Whilst inside vim, when I go to insert mode and then use C-[0 to escape insert mode and move to the first character on the line, tmux grabs the key first and complains: Window not found: :0 ** I tried all sorts of things in my .tmux.conf, but nothing works. I thought it might be a terminal or shell issue, but confirmed same behaviour on a configless machine using Bash and [Gnome] Terminal. So the question really is, how do I unbind the C-[ key from tmux? ** I have base-index 1 set.

• Why my AD domain doesn't work on my laptop

  - by Frederick Marcoux

  I have installed Windows Server 2008 R2 on a virtual machine with a bridged network card and installed Active Directory. I configured it and when I try to connect my laptop to the domain name, in this case, creationsmicroweb.ca (doesn't exist, don't try, for local only), I can't get connected. My laptop just doesn't see it. I don't know why! There's a resume of my config: Domain Name: creationsmicroweb.ca Forest: new, principal domain controller IP: Fixed (192.168.1.100) DNS Name: none (just for local, I ignored them) NETBIOS name: MICROWEB If someone as found why, please help me! This is for my business that I'm starting and I can't find why it doesn't work!

• How to debug suspend?

  - by mlissner

  I've been using Ubuntu for about five years now, and I still can't make it suspend when I want to. It's quite irritating that I can program up a storm, hack the machine in numerous other ways, and yet, and yet when I try to make it suspend or debug suspend, I fail miserably. I need help. Where do I begin to find the problem? What do I do to fix it? I'm placing a bounty on this, because I've literally lost hours of my life to this problem, and leaving my computer on ALL the time is terrible. The symptoms: Pressing suspend brings my computer to a state where it has a blinking cursor, the fans are running, it seems that the HD has turned off (I think), and I can't do anything to bring it back from this state (short of a hard reboot). Possibly related: My fans stay on even after a shutdown, and even then, I have to press the power button for five seconds before I can start it up again. I don't know what logs to look at to debug the problem, and I imagine they'd get nuked on reboot anyway. Please, please help. This drives me completely nuts, and I've been living with it for over a year.

• Sharing folders with VirtualBox, Win7 Host and Ubuntu 9.10 Guest

  - by unknown (google)

  I have a development setup from this tutorial: http://www.sitepoint.com/blogs/2009/10/27/build-your-own-dev-server-with-virtualbox/ But what I can't figure out is how to share a folder on my Ubuntu virtualized machine with the host Win7. I want to use a Windows text editor to edit code that's on my Ubuntu server. I've tried using the Shared Folders setting, adding "/var/www" but it says that the path is not absolute. When I click on "other", it only allows me to browse folders on my Win7 host. Both the host and guest are 64-bit OS. Thanks in advance!

• How to allow an internal server accept remote connections not through RD Gateway

  - by Matt Ahrens

  So, I help administrate a collection of servers running various windows server environments. We have a RD Gateway server, properly configured, to gatekeep for us. It does not have the other servers listed in it's server farm category, though. I just added a refurbished server for a non-profit development environment that is sharing the rack space and port. I would like this server to be accessible via remote connection, but not require RD gateway certification (I cannot add the users for this development server to our gateway since they do not work for the organization hosting the rack.) Is there any way for me to add this dev. server as an exception to which servers should require RD Gateway clearance, or otherwise let users bypass RD gateway credentials for this one machine? Thanks, and let me know if I am misinformed on how RD gateway works or anything. I am still learning.

• Configure IIS 7 Reverse Proxy to connect to TeamCity Tomcat

  - by Cynicszm

  We have an IIS 7 webserver configured and would like to create a reverse proxy for a TeamCity installation using Tomcat on the same machine. The IIS server site is https://somesite and I would like the TeamCity to appear as https://somesite/teamcity redirecting to http://localhost:portnumber. I have installed the IIS URL Rewrite extension and the Application Request Routing to try and setup a reverse proxy but can't get it working. The closest answer I found is an old StackOverflow question: http://stackoverflow.com/questions/331755/how-do-i-setup-teamcity-for-public-access-over-https which unfortunately doesn't have any working example. I've searched a quite a bit but can't seem to find a relevant example. Any help is appreciated!

• Modifying kernel shared memory settings on a lion install

  - by andrewjl

  What's the location of the sysctl.conf file on lion? In Snow Leopard it was in /etc/sysctl.conf but now that folder doesn't contain it anymore. Searching for the file in spotlight yields no results. Have the shared memory settings been moved to a different conf file? What is it's name? EDIT I am trying to modify the kernel shared memory settings of the machine. When I didn't find the sysctl.conf file in the right place, I created my own with the recommended settings and put into /etc directory. However running sysctl -a still shows me that the old memory settings are in place. How do I go about modifying these on a lion install?
