• accessing live usb files from new hd ubuntu install

  - by Robin Bailey

  After my live USB (ubuntu 12.04 lts) refused to boot, I proceeded to install the same Ubuntu version on the laptop hard drive (a dual boot next to Win xp). This all went well without a hitch. Previous to this, I spent several weeks enjoying and exploring ubuntu from the usb pendrive. During this time I changed lots of settings and customized Firefox and more. Now, I'd like to import the home folder from the usb drive into the new install home folder on the hard disk, which is the purported folder that holds all those special settings to my knowledge. Unfortunately and only being familiar with Windows file systems, the view of the usb file system from the new hdd install is totally perplexing. I can't find anything that looks anywhere close to the original file system. More, I can't find any of the files I had created and stored there, like the LibreOfficeCalc file that has all my passwords (this one is really discouraging) that was stored on the ubuntu desktop. Help me find this file alone and I'll bow down with full apologies to any and all computer gods. Being able to import all those customizing settings into the new install would be a major bonus also, but hey, I'm not greedy. I'll take the passwords file and be happy! And humble! I would be very grateful for some clear, understandable help on this. Thanks

• Is there a better way to run ubuntu from usb disk

  - by Adam Butler

  I have an old laptop with a broken hard drive controller and am running the previous ubuntu from a usb. I installed this as per standard instructions by running some program that copied the live cd to the usb. This has had a few problems, it seems like it was just made for trying and not for everyday use. Ideally I would like to do a proper install to the usb disk instead of just running off the installer disk. Is there a way to do this? The main problems I have are: When adding mounts to fstab it gets overwritten on each reboot When installing updates the kernel cannot be updated

• Mouse takes a while to start working after boot

  - by warkior

  I just recently installed Ubuntu 12.04 (64 bit) and a number of my USB devices have stopped working. At least, they don't work for the first 3-5 minutes. I have two mice (one wireless, one wired) and a camera, which seem to take Ubuntu 3-5 minutes to recognize after booting up. Eventually, they do start to work, but it takes ages! lsusb results: (when the mice are working...) $ lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 002: ID 046d:c512 Logitech, Inc.

• SQL Authority News – Download Microsoft SQL Server 2014 Feature Pack and Microsoft SQL Server Developer’s Edition

  - by Pinal Dave

  Yesterday I attended the SQL Server Community Launch in Bangalore and presented on Performing an effective Presentation. It was a fun presentation and people very well received it. No matter on what subject, I present, I always end up talking about SQL. Here are two of the questions I had received during the event. Q1) I want to install SQL Server on my development server, where can we get it for free or at an economical price (I do not have MSDN)? A1) If you are not going to use your server in a production environment, you can just get SQL Server Developer’s Edition and you can read more about it over here. Here is another favorite question which I keep on receiving it during the event. Q2) I already have SQL Server installed on my machine, what are different feature pack should I install and where can I get them from. A2) Just download and install Microsoft SQL Server 2014 Service Pack. Here is the link for downloading it. The Microsoft SQL Server 2014 Feature Pack is a collection of stand-alone packages which provide additional value for Microsoft SQL Server. It includes tool and components for Microsoft SQL Server 2014 and add-on providers for Microsoft SQL Server 2014. Here is the list of component this product contains: Microsoft SQL Server Backup to Windows Azure Tool Microsoft SQL Server Cloud Adapter Microsoft Kerberos Configuration Manager for Microsoft SQL Server Microsoft SQL Server 2014 Semantic Language Statistics Microsoft SQL Server Data-Tier Application Framework Microsoft SQL Server 2014 Transact-SQL Language Service Microsoft Windows PowerShell Extensions for Microsoft SQL Server 2014 Microsoft SQL Server 2014 Shared Management Objects Microsoft Command Line Utilities 11 for Microsoft SQL Server Microsoft ODBC Driver 11 for Microsoft SQL Server – Windows Microsoft JDBC Driver 4.0 for Microsoft SQL Server Microsoft Drivers 3.0 for PHP for Microsoft SQL Server Microsoft SQL Server 2014 Transact-SQL ScriptDom Microsoft SQL Server 2014 Transact-SQL Compiler Service Microsoft System CLR Types for Microsoft SQL Server 2014 Microsoft SQL Server 2014 Remote Blob Store SQL RBS codeplex samples page SQL Server Remote Blob Store blogs Microsoft SQL Server Service Broker External Activator for Microsoft SQL Server 2014 Microsoft OData Source for Microsoft SQL Server 2014 Microsoft Balanced Data Distributor for Microsoft SQL Server 2014 Microsoft Change Data Capture Designer and Service for Oracle by Attunity for Microsoft SQL Server 2014 Microsoft SQL Server 2014 Master Data Service Add-in for Microsoft Excel Microsoft SQL Server StreamInsight Microsoft Connector for SAP BW for Microsoft SQL Server 2014 Microsoft SQL Server Migration Assistant Microsoft SQL Server 2014 Upgrade Advisor Microsoft OLEDB Provider for DB2 v5.0 for Microsoft SQL Server 2014 Microsoft SQL Server 2014 PowerPivot for Microsoft SharePoint 2013 Microsoft SQL Server 2014 ADOMD.NET Microsoft Analysis Services OLE DB Provider for Microsoft SQL Server 2014 Microsoft SQL Server 2014 Analysis Management Objects Microsoft SQL Server Report Builder for Microsoft SQL Server 2014 Microsoft SQL Server 2014 Reporting Services Add-in for Microsoft SharePoint Reference: Pinal Dave (http://blog.sqlauthority.com)Filed under: PostADay, SQL, SQL Authority, SQL Download, SQL Query, SQL Server, SQL Tips and Tricks, SQLAuthority News, T SQL

• MS12-070 : Security Updates for all supported versions of SQL Server

  - by AaronBertrand

  This week there was a security release for all supported versions of SQL Server . Each version has 32-bit and 64-bit patches, and each version has GDR (General Distribution Release) and QFE (Quick-Fix Engineering) patches. GDR should be applied if you are at the base (RTM or SP) build for your version, while QFE should be applied if you have installed any cumulative updates after the RTM or SP build. ( More details here .) SQL Server 2005 RTM, SP1, SP2, SP3 - not supported SP4 - GDR = 9.00.5069,...(read more)

• USB hub keep changing ports

  - by Danniel Magno

  I have an external powered USB hub and I'm using gammu to send some SMSs, but every time the daemon connect to one specific modem, it has the port changed. Gammu is able to send just one SMS and after that the port is changed. I've already tried using: /dev/ttyUSB3 /dev/serial/by-path/pci-0000:00:0b.0-usb-0:3.4.3:1.0-port0 There is anything to do which will stop the ports to be changed or use any other fixed port? Thanks.

• SQL SERVER – Resolving SQL Server Connection Errors – SQL in Sixty Seconds #030 – Video

  - by pinaldave

  One of the most famous errors related to SQL Server is about connecting to SQL Server itself. Here is how it goes, most of the time developers have worked with SQL Server and knows pretty much every error which they face during development language. However, hardly they install fresh SQL Server. As the installation of the SQL Server is a rare occasion unless you are DBA who is responsible for such an instance – the error faced during installations are pretty rare as well. I have earlier written an article about this which describes how to resolve the errors which are related to SQL Server connection. Even though the step by step directions are pretty simple there are many first time IT Professional who are not able to figure out how to resolve this error. I have quickly built a video which is covering most of the solutions related to resolving the connection error. In the Fix SQL Server Connection Error article following workarounds are described: SQL Server Services TCP/IP Settings Firewall Settings Enable Remote Connection Browser Services Firewall exception of sqlbrowser.exe Recreating Alias Related Tips in SQL in Sixty Seconds: SQL SERVER – FIX : ERROR : (provider: Named Pipes Provider, error: 40 – Could not open a connection to SQL Server) (Microsoft SQL Server, Error: ) SQL SERVER – Could not connect to TCP error code 10061: No connection could be made because the target machine actively refused it SQL SERVER – Connecting to Server Using Windows Authentication by SQLCMD SQL SERVER – Fix : Error: 15372 Failed to generate a ser instance od SQL Server due to a failure in starting the process for the user instance.

• USB resets with Ubuntu 9.10

  - by Grumbel

  Since the upgrade to Ubuntu 9.10 I have issues with getting USB device resets on my Maxtor OneTouch USB harddrive: Nov 9 20:54:37 localhost kernel: [32459.100021] usb 2-2: reset high speed USB device using ehci_hcd and address 4 Nov 9 21:54:37 localhost kernel: [36059.100017] usb 2-2: reset high speed USB device using ehci_hcd and address 4 Nov 9 23:24:37 localhost kernel: [41459.112025] usb 2-2: reset high speed USB device using ehci_hcd and address 4 The device itself continues to work fine, the resets however wake the device out of its sleep state and thus cause it to spin up, which is very annoying. Interestingly, as the log shows, the resets happen at pretty regular intervals (i.e. one hour or half an hour), not randomly. An USB card reader seems to have the same issues, while another USB harddrive from a different manufactor works fine on the same PC. What could be causing this and how could I fix it?

• How to create a bootable USB stick?

  - by Deborah Shadovitz

  I am looking at this: http://www.ubuntu.com/download/help/create-a-usb-stick-on-ubuntu I need to create a boot disk to test Ubuntu to make sure it will run on a PC (Compaq Mini CQ10-120LA) I was given. I can create the boot disk off of a Mac (in English) or Windows (but Windows is in Spanish and foreign to me). Questions: What format do I choose for the USB stick? (I wish the instructions stated this). What is Dash? (Will I know when I run the installer?) Can I do this from a Mac or Windows computer? Or only from Ubuntu?

• Can not update Natty running from a USB stick

  - by Ingo Gerth

  In a blogpost Jono explained a nice way to test the latest version of Natty. Under point four he proposes: Step 4: Update Although you installed the latest daily you should ensure it is up to date, and you can do this with: sudo apt-get update sudo apt-get upgrade Now, I followed all the steps and am actually writing this question from a session running on a 4GB USB stick. When trying to update the installation though (I just tried to do that using the Update Manager), it always fails because I do not have enough disc space remaining. How can I get Ubuntu to update properly on my USB stick?

• Unable to view USB stick/drive contents

  So, I plug-in my USB stick, copy a file from the hard drive to the USB stick, and safely remove the USB stick. I then plug out the USB stick. When I plug the USB stick back into the computer again, the previous contents of the USB stick are all gone. It shows an empty drive. I am using Windows XP SP 2 with an 8 GB USB stick from Transcend.

• Installing Ubuntu to a USB drive

  - by Carl Smotricz

  I'm having a rough time getting Ubuntu to run from a 250 GB USB hard drive. I booted Ubuntu 9.10 from a CD and ran the regular "install" to the attached USB drive. I used the "advanced" option on the drive partition question to put the boot loader on /dev/sdb (the USB disk) but when I boot the machine it doesn't recognize there's a boot loader on the USB drive (it offers to boot from 2 other devices but not the USB disk). I also tried booting from the Ubuntu CD and using usb-creator-gtk to set up the USB drive. Seems to me this is meant to work with flash drives. I got a bootable USB disk but it looked and worked like the CD, i.e. it gave me options of "live CD" operation, installing, memtest, etc. That's not the way I want to run the system. Some help in installing Ubuntu, bootable into a "full" running system on my USB drive would be appreciated.

• SQL SERVER – Color Coding SQL Server Management Studio Status Bar – SQL in Sixty Seconds #023 – Video

  - by pinaldave

  I often see developers executing the unplanned code on production server when they actually want to execute on the development server. Developers and DBAs get confused because when they use SQL Server Management Studio (SSMS) they forget to pay attention to the server they are connecting. It is very easy to fix this problem. You can select different color for a different server. Once you have different color for different server in the status bar, it will be easier for developer easily notice the server against which they are about to execute the script. Personally when I work on SQL Server development, here is the color code, which I follow. I keep Green for my development server, blue for my staging server and red for my production server. Honestly color coding does not signify much but different color for different server is the key here.

• How can I hard reset a USB device?

  - by Cory

  I have a USB device (a modem) that is really finicky. Sometimes it works fine, but other times it refuses to connect. The only solution I have found to fix it once it gets into a bad state is to physically unplug the device and plug it back in. However, I don't always have physical access to the machine it is plugged in on, so I'm looking for a way to do this through the command line. This post suggests running: sudo modprobe -w -r usb_storage; sudo modprobe usb_storage However I get an "unknown option -w" output. This slightly modified command: sudo modprobe -r usb_storage Fails with the message FATAL: Module usb_storage is in use. If I try to kill -9 the processes marked [usb-storage] before running they refuse to die (I think because they are deeply tied to the kernel). Anyone know of a way to do this? NOTE: I cross-posted this on superuser.com as I didn't know which was more appropriate. I will delete and/or link whichever one is answered first.

• external drive and CentOS - Reset high speed USB device number

• Choppy USB mice on just one of USB ports

  - by user20532

  I've got Lenovo b560 laptop with latest, properly updated Kubuntu on it (11.04 natty, kernel 2.6.38-8-generic). It has three USB2.0 ports onboard. I usually plug a mouse into one of them (I've got 3 different mice - in office, at home and for when on the go). Sometimes, usually after laptop awakening from sleep, the mouse still works but cursor movements are choppy, as if the processor was extremely loaded (it's usually not). I found that if I re-plug the mouse cord into the other USB port, it works just fine. If I plug it back to problematic port, it is still choppy and remains choppy until next boot. Of course I want my mice to always work fine. Problem is: I cannot reproduce this behavior for sure, it happens sporadically but regularly. I use different USB ports (problem has ever happened on each of them since), I use different mice (each has failed me this way at least once), I cannot generally find what exactly is going wrong and why plugging to different port fixes the mouse instantly. So I'd like to hear at least clues where to look at, what to try to identify my problem. A bit of update: while beginning this post, I had the issue once again. I have just replugged the mouse back to problematic port and it is not recognized at all. On the other port it works smoothly.

• External USB 3 drive not recognized

  - by ilan123

  Ubuntu 12.10 64 bit seems not to recognize my external hard disk. It is a Vantec NST-310S3 external disk enclosure with a WD 3TB drive. The disk has two NTFS partitions. My PC is a dual boot system. Under Windows 7 the hard disk works fine but I can't make it work with Ubuntu. When the drive is connected to the PC then the command sudo fdisk -l seems to hang forever. Below are the output of lsusb and cat /proc/partitions without the external drive and then with it connected. I added also the last lines of the dmesg command at the end.

• Windows Server 2003 Terminal Server does not give out all available licenses

  - by Erwin Blonk

  I installed the Terminal Server role in Windows Server 2003 Standard 64-bits. Still, only 2 connections are allowed. The License Manager says that there are 10 Device CALs available, which is correct, and that none are given out. For good measure I let the server reboot, to no effect. Before this, there was another server (same Windows, except that it is 32 bits) active as a licensing server. I removed the role first and then then added it to the new server. I then removed the Terminal Server Licensing Server component off the old one and added it to the new one. After that, I added to licenses. When that didn't give the required result, I rebooted to new server. Still, the new server, with licenses and all, acts as if it has the 2 license RDP. The server are all stand-alone, there is no active directory been set up. Both servers are in different workgroups. Update (4/12/10): The server has changed the entries in the Terminal Server Licensing a few times. After installing the licenses it added an entry of which the exact phrasing I forgot but it was about temporary Windows 2003 device licenses. Later it added Windows Server 2003 - TS Per Device CAL. The temporary held 2 licenses (standard RDP licenses, I think) and the other 10. At some point, seemingly unrelated from the testing we did, it used a licenses from the new pool. This morning, 2 licenses were used from the pool of 10 and only 1 from the temporary/RDP pool (I wish I had screenshots to show, it changed every few hours oir so it seems). Although I had already activated the server over the internet, and re-activated it, I decided to go through the whole procedure by phone. Long story short, here is what it says now: Existing Windows 2000 Server, type:built-in [no licenses used, I add for for sake of being complete] Windows Server 2003 - Terminal Server Per Device CAL Token, type:open [none of 10 used] Windows Server 2003 - TS Per Device CAL, type:open [3 of 10 used] As I tried to explain, this is the end result after a few changes, most of which I can't directly connect to any action from my part. Only going to the activation procedure by phone seemed to directly effect the TS, resulting in the above configuration. Still, it is impossible to connect with more than 3 people, which is 1 up from the 2 that could connect yesterday. TS does say 7 licenses are avaible. Yet it won't give them out.

• USB modeswitch to mass storage device

  - by Andrew

  I'm trying to install a Sierra AirCard 320U (branded as "Telstra USB 4G") into a VirtualBox Windows XP machine, on an Ubuntu 10.10 host. usb_modeswitch offers me a way to disable the "mass storage device" option, but I can't see a way to permanently re-enable it so it's usable by VirtualBox (device filters briefly detect it but then it disappears again). lsusb shows the device as: 0f3d:68aa Airprime, Incorporated When I first insert the device, it shows as 1199:0fff Sierra Wireless, Inc. Is there any way to re-enable the storage device so VirtualBox can see it?

• Logitech USB headset not working on 12.04

  - by thepeoplescoder

  I've looked around for answers to this question, But none of them seem to work for my particular problem. Obviously my USB headset isn't working, But I might as well share the scenario. I am running Ubuntu 12.04 and I have a Logitech USB headset. The relevant output from dmesg is as follows: [160708.528047] usb 2-1.2: USB disconnect, device number 9 [160768.890123] usb 2-1.2: new full-speed USB device number 10 using ehci_hcd [160768.997578] input: Logitech Logitech USB Headset as /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.3/input/input15 [160768.997795] generic-usb 0003:046D:0A0C.0005: input,hidraw0: USB HID v1.00 Device [Logitech Logitech USB Headset] on usb-0000:00:1d.0-1.2/input3 When I go to System Settings - Sound, My headset shows up in both the Output and Input tabs, It is called "Clear Chat Comfort USB Headset" in those tabs, But I doubt that's a serious issue. When I click my headset in either tab to use it, The changes are not remembered when I reopen the sound settings, the built-in audio is still used. Also when I select the headset in the Output tab, and click the Test Sound button to test everything, The sound still comes from my laptop's onboard audio, instead of from my USB headset. Does anyone know how to correct this? I am stumped.
