• Can't install Ubuntu on my Windows 7 laptop

  - by Ana

  I tried installing Ubuntu in two different ways: First, I tried the Windows Installer, and it goes well until I reboot the system and, when booting on Ubuntu, I get the error: No root file system defined. Second, I uninstalled wubi by going to to Control Panel - Uninstall Programs - Ubuntu. Then, I booted the laptop from the live CD and selected install. It boots okay but in the screen right after the one that says to make sure you have 4.5 GB available, Internet connection, etc, when I click continue it throws me a message saying that Ubuntu had an internal error and asks me if I want to report the error. After that, I just have a black screen and nothing else! No Ubuntu installed, no boot option to go back to Windows. Nothing! My goal is to install Ubuntu alongside Windows 7 (without the hassle of formatting the computer, creating partition, etc). How can I do it (preferable using Windows Installer)? How can I solve the "No root file system defined" that I encountered when I used the Windows Installer?

• Music but no voices on headphones

  - by TheEmeritus

  I have a laptop with Windows 7 and I have headphones for a couple of months, and only recently they started to play only the music, while the voices are there, but just very faint. I tried to connect them to another computer (PC, windows XP) and they worked fine, which made me think the problem isn't with the headphones but with the laptop. I've searched online and found a few solutions, none of the seemed to work. Such as: plugging in and out my jack until you can hear better, checking the headphones on other computers. Other relevant info: The headphones come with a mic if I right click the sound icon - sound devices. Then I dont see any 'headphones', not even if I tell it to show disabled devices. All I see is a 'speakers' icon, yet it's there even if the headphones are disconnected, and is always active. So if anyone has any idea I'd appreciate it :) Thanks!

• How can I find and remove 6to4 from my system?

  - by Kelley

  Last week I installed Miredo and configured my system to handle IPv6 through 6to4 tunneling. It was easy and it worked well. So I decided I'd give Hurricane Electric's IPv6 connection a try. I've had a lot to learn, and I thought I had it all running (with a great deal of help from a very patient person at Hurricane: my LinkSys E3200 didn't like IPv6). But now, when all should be good, after I uninstalled Miredo and Teredo and whatever else, I find that there is "6to4 tunneling - another automatic tunneling," which I need to remove from my box. But I have no idea where or what it might be. Connected to my computer are a couple printers, an external hard drive, and a router (which has no settings for IPv6). All of these are, I think, innocent in this matter. So, how can I get rid of 6to4 tunneling, when I don't even know where it is? Is there someplace to look and find out what's going on? I'm pretty new to Linux and Ubuntu.

• How to forward external port to internal port using plink

  - by user857990

  For a penetration test where I have shell access to a computer running an old Windows, I'd like to forward port 4450 to 127.0.0.1:445 because the firewall is blocking 445 externally. I'm stuck on the following: plink -L 4450:127.0.0.1:445 SSH-Server According to the documentation I've found, I'd have to specify a SSH-Server. But all documentation I've found just uses an SSH-Server in the same network. To forward it to a localhost port, that wouldn't help. Do I have to install an SSH-Server on that machine or are there other ways?

• Accidentally replaced the partition table using GParted in UBUNTU

  - by claws

  Hello, This machine has UBUNTU & wINDOWS XP. I'm currently logged into UBUNTU. I was just checking the features of GParted and accidentally clicked Device > Create Partition Table. A default MS-DOS partition table is created. Now if I re-start the Gparted there is nothing. Its showing entire disk as UNALLOCATED space. Lucky thing is All the drives (C:, D:, E:) are currently mounted and I'm in UBUNTU. I guess its possible to re-create the partition table using current status. But I don't know how? Can any one kindly tell me how to do this. This is a lab computer. If its not recoverable. I'm completely screwed!!

• Is there an easy way to read blu-rays on Windows?

  - by ereOn

  Some time ago, I bought my parents a computer dedicated to medias (mostly photographs and movies trough DLNA). My father asked me if he could read blu-ray on it, so I bought a blu-ray reader but I can't find a software to do the playback. I installed PowerDVD (a free version we got with a Blu-Ray) but it seems it now requires a (non-free) upgrade. Even if it were free, I hardly see my parent do the upgrade by themselves as they barely understand how computers work. I thought I would find a free software (something like VLC, but for blu-rays) but so far had no luck. Do you guys have a software to suggest that would solve my issues ? It should run on Windows Vista, shouldn't require an update every monday, or at least a free one. Thank you very much.

• Restore audio settings - cannot open mixer: No such file or directory

  - by Alfred M.

  The internal speaker of my laptop never functionned under Ubuntu. I tried to follow indication on the web and now the jack audio does not work either. The graphic interface for audio management now displays a 'dummy output' instead of the three possible outputs I used to have (one of them was working for the jack output). In a terminal alsamixer raises an error: cannot open mixer: No such file or directory I did try to remove and reinstall alsa-utils but it did not change anything. This happened after a failed atempt to install alsa-driver-linuxant_1.0.23.1_all.deb from here. My sound card seems to be not recognised anymore. After reboot I have no more the sound icon in menu bar the upper right corner. I think I have removed my sound card driver. Indeed, the command sudo lshw -class multimedia indicated audi device as unclaimed. Any idea how I could revert to a better situation (that is jack support and alsa working)? EDIT: The command lspci -nnk | grep -iEA3 audio gives lspci -nnk | grep -iEA3 audio 00:1b.0 Audio device [0403]: Intel Corporation 82801I (ICH9 Family) HD Audio Controller [8086:293e] (rev 03) Subsystem: ASUSTeK Computer Inc.

• Can't ping some IP addresses in the same subnet (LAN) Windows 2011 Server

  - by Ricardo

  Hi I’m running in Windows Small Server 2011 server standard (192.168.1.108), it’s my dhcp and dns server too, but suddenly all other users can’t get internet. My gateway is 192.168.1.1. After a lots of tested I can saw that my server can’t get into the router (192.168.1.1), and also into some others computers, but some other computers answer the ping command. In fact the same computer with the IP 192.168.1.9 didn't answer, but with the IP 192.168.1.63, it response! I have no routers, firewall, vlans or anything that disallow the traffic between computers, in fact when I changed the server IP address (192.168.1.109), I be able to ping the other computers and gateway, but if a back to the 192.168.1.108 the trouble comeback. I hope you can help me with this issue Ricardo

• Different keyboard layouts at same time for different devices

  - by Joao Carlos

  I have a MacBook Pro running Snow Leopard, and I am using it as a portable but also desktop computer. In order to acheive this, I bought a VGA adapter and I am using it with an external mouse, keyboard, and monitor. The problem is, the external keyboard layout is different from the one on the macbook. It is set to US qwerty (its a logitech G15), and because of that, most keys behave differently than they should. Question is, how can I set up different layouts at same time for different devices? I want US for external keyboard and PT for the default one.

• Are programmers getting lazier and less competent

  - by Skeith

  I started programming in C++ at uni and loved it. In the next term we changed to VB6 and I hated it. I could not tell what was going on, you drag a button to a form and the ide writes the code for you. While I hated the way VB functioned I cannot argue that it was faster and easier than doing the same thing in C++ so i can see why it is a popular language. Now I am not calling VB developers lazy in just saying it easier than C++ and I have noticed that a lot of newer languages are following this trend such a C#. This leads me to think that as more business want quick results more people will program like this and sooner or later there will be no such thing as what we call programming now. Future programmers will tell the computer what they want and the compiler will write the program for them like in star trek. Is this just an under informed opinion of a junior programmer or are programmers getting lazier and less competent in general? EDIT: A lot of answers say why re invent the wheel and I agree with this but when there are wheels available people are not bothering to learn how to make the wheel. I can google how to do pretty much anything in any language and half the languages do so much for you when it come to debugging they have no idea what there code does of how to fix the error. That's how I cam up with the theory that programmers are becoming lazier and less competent as no one cares how stuff works just that it does until it does not.

• Why does my terrain turn white when I get close to it?

  - by Starkers

  When I zoom in on my terrain it goes white: The further in I zoom, the greater the whiteness becomes. Is this normal? Is this to speed up rendering or something? Can I turn it off? I'm also getting these error messages in the console over and over again: rc.right != m_GfxWindow-GetWidth() || rc.bottom != m_GfxWindow-GetHeight() and GUI Window tries to begin rendering while something else has not finished rendering! Either you have a recursive OnGUI rendering, or previous OnGUI did not clean up properly. Does this bear any correlation on the issue? Update I create virtual desktops to flit between using the program Deskpot. Turning this program off and restarting has stopped the above errors appearing in the console. However, I still get white terrain when I zoom in. Not a single error message. I've restarted my computer to no avail. I have an Asus NVidia GeForce GTX 760 2GB DDR5 Direct CU II OC Edition Graphics Card. Any known issues? Update I don't think it's fog...

• How to change system time or force a time sync

  - by cpury

  My laptop is probably running out of CMOS battery, I know I have to fix it soon, but until then, this very annoying issue keeps me from using it. Scenario: My system clock is reset to 15/12/08 11:00 AM every time I turn on my computer. This has all sorts of side-effects, one of the more annoying being that I can't log into my gmail. At first I just waited for a time sync to happen, as I have that activated and all. It never happened. I googled and didn't find any way of enforcing a time sync, which I found very strange. Is there really none? Setting the time and date by hand is also a problem. For my 12.10 installation, the time & date settings are bugged. I remember it being for my last, older installation as well, though. Of course the easiest way should be to just manually edit the date and time fields by entering a new date. This is possible in theory, but the changes are reverted as soon as the text boxes loose focus. The other way to do it is to click the +-buttons for a long, long time. The first time I did that, the changes weren't stored either. I found out that afterwards I have to switch from manual to internet-sync mode and wait ~5 seconds until the in the top left corner of my system the new time is shown, or otherwise it won't have effect. So a nice solution would be one of the following: Setting the time/date by hand, maybe via terminal, so I can just enter the right values. Or, a command that would enforce an immediate time sync, that I can run after booting. I know I have to change the batteries soon, but this is seriously keeping me from working...

• Driver choice for addressing ubuntu wireless card issues

  - by Holly

  Hello, this should be a relatively simple question. I'm attempting to get my windows wireless card to work with ubuntu, booted from my portable hard drive. This is the guide I'm attempting to follow is on help.ubuntu.com, /community/WifiDocs/Driver/Ndiswrapper My wireless card is a Broadcom Corporation BCM4318 AirForce One 54g 802.11g Wireless LAN Controller. My computer is an HP Pavilion Entertainment dv5 notebook, which came with Vista 64. I would like confirmation about which of the drivers I should use. At this point, I'm leaning towards Broadcom BCM4318 HP Pavilion zv6000, but I thought it best to ask advice before taking action. The drivers I have to chose from are listed on this page http://sourceforge.net/apps/mediawiki/ndiswrapper/index.php?title=Category:Broadcom Thanks! Holly

• Install Nod32 antivirus silently?

  - by IT Tech

  Hi guys/gals, I was hoping that I could find someone on here that may know if it is possible to install Nod32 on a client PC silently. We have some software that will copy the MSI to the remote PC and run it with any specified parameters. The software needs you to import the license key file and tell it where the server is. Is there any way that these details can be pre specified so the user doesn't have to have any interaction on the remote computer. Many thanks in advance.

• From physics to Java programmer?

  - by inovaovao

  I'm a physics phd with little actual programming experience. I've always liked programming and played around with Basic and Pascal (also VB and Delphi) as a teen, but the largest actual project I completed was an assignement for the introductory computer science class in university where I wrote a nice little program (about 1500 lines of pascal) to display functions of 2 variables in 3D. I've had also a couple other projects of a few hundred lines range, but during my phd I didn't have (or take) the time to program more (string theory is hard guys!), beside playing around with ruby. Now I've decided that I'm more interested in programming than in physics and started to learn Java (hoping to pass the certification exam next week) and OO design. Still, I have trouble deciding on what to focus next (Java EE? Web development? algorithms and C programming?) in order to maximize my employement chances. Bear in mind that I'm aiming (mostly) at the swedish job market and that I'm 30 years old. So for the questions: Do you think that I have any chances to start and make a career in IT and programming coming from physics? What would be the best strategy to maximize my value in the field? Do you have suggestions as to where my physics background might be useful?

• Kerberos: connection from win app running from IIS to SQL failed

  - by Mikhail Kislitsyn

  I have an IIS web-application with Windows authentication and impersonation. This application connects to SQL server. In this case Kerberos works fine. But there is a problem. Web-application runs windows application (not .NET), which also connects to the SQL server. Windows application runs with IIS app user credentials and impersonates current site user to connect to SQL server. scheme: http://i.stack.imgur.com/2cgv7.png When delegation for IIS user is set to "Trust this computer for delegation to any service" everything works fine. But I can't use this type of delegation according to security requirements. When I set delegation to "Specific services" and choose MSSQLSvc SPN, connection from windows application fails with "ANONIMOUS" fault. WireShark shows "KRB5KDC_ERR_BADOPTION" packet. What I'm doing wrong?

• Can the Windows 8.1 update be applied without local terminal?

  - by Ben Voigt

  It is possible to access the Windows Store from a remote desktop session and initiate the Windows 8.1 Update from the Windows Store, but the update hangs after the first reboot, likely waiting for the user to accept the license check. This leaves the computer unusable remotely. Is there a way to pre-accept the license terms so that the update can complete autonomously? Perhaps an UNATTEND.XML such as would be used for an unattended clean install? Failing that, is there a way to connect with remote desktop during that phase of the install (it appears to be GUI-mode setup running with the usual Windows kernel and full OS)?

• Bacula not backing up all the files it should be doing

  - by Nigel Ellis

  I have Bacula (5.2) running on a Fedora 14 system backing up several different computers including Windows 7, Windows 2003 and Windows 2008. When backing up the Windows 2008 server the backup stops after a relatively small amount has been backed up and says the backup was okay. The fileset I am trying to backup should be around 323Gb, but it manages a mere 27Gb before stopping - but not erring. I did try creating a mount on the Fedora computer to the server I am trying to backup, and Bacula managed to copy 58Gb. When I tried to use the mount to copy the files manually I was able to copy them all - there are no problems with permissions etc. on the mount. Please can anyone give a reason why Bacula would just stop? I have heard there is a 260 character limit, but some of the files that should have been copy resolve to a shorter filename than some that have been backed up.

• Where did this incorrect cached DNS lookup come from?

  - by Stephen Jennings

  Somehow, I've been having a chronic issue where my computer will get an invalid DNS lookup in its cache for either of the two Exchange servers I use from Mail.app. My workplace runs one of the Exchange servers and I run the other (they are totally unrelated, hosted by different companies, etc.). The problem manifests as a certificate domain error. When it happens, I can run nslookup mail.mydomain.com and I see the incorrect IP address (usually owned by either Apple or Akamai), but if I run nslookup mail.mydomain.com 8.8.8.8, I get the correct address. My real quest is to find out why this keeps happening, and to do that, I'd like to know which server is supplying me this bad DNS entry. Is there a way to check my DNS cache to see where this bad lookup came from?

• Android tethering question

  - by Solignis

  Hi there, I have a Motorola Droid 1 with Android 2.2 on it. I found something odd that I don't understand why it works. If I plug my phone into my home computer which is Windows 7 and I turn on the tethering ability, I am met with a Verizon captive portal and it tells me I need to pay for a tethering plan (which I don't have). Now the weird thing, if I plug the same phone into my Ubuntu 10.10 laptop and enable tethering it works and can get on the internet with no captive portal showing up. The only thing I could notice that was different about the connections was Windows connected to the phone with an NDIS driver and Linux connected to the phone with what I think is a raw device mapping. Would that have anything to do with it?

• Wireless not working on desktop with Asus USB-N13 (B1) wireless adapter

  - by user900749

  I am trying to connect my desktop to a wireless network. I have purchased an ASUS USB-N13 B1 adapter. I have followed instructions for installing drivers and disabling conflicting drivers. I have thoroughly searched and could not find a solution. The adapter is recognized and powered on. I have entered the ssid and password information into the wireless network configuration. Other machines can connect to this wireless network, and the machine can connect online via ethernet without issue. Here is the output of some commands which summarize my configuration, and might give some clues : ~$ cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=12.04 DISTRIB_CODENAME=precise DISTRIB_DESCRIPTION="Ubuntu 12.04.1 LTS" ~$ uname -a Linux petra 3.2.0-29-generic #46-Ubuntu SMP Fri Jul 27 17:03:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux ~$ lsusb Bus 001 Device 006: ID 0b05:17ab ASUSTek Computer, Inc. ~$ dmesg [ 1883.823150] wlan0: authenticate with 48:5b:39:e7:25:5e (try 1) [ 1884.020027] wlan0: authenticate with 48:5b:39:e7:25:5e (try 2) [ 1884.220025] wlan0: authenticate with 48:5b:39:e7:25:5e (try 3) [ 1884.420023] wlan0: authentication with 48:5b:39:e7:25:5e timed out Any assistance would be appreciated as I have been trying to get this machine online for several weeks now to no avail.

• How do I install windows wireless driver for TP-Link TL-WN7200ND

  - by Jim

  I'm using the TP-Link TL-WN7200ND USB wireless adapter. I have downloaded the Windows drivers and updated Ubuntu to 10.10 by manually connecting the computer to the router. I also installed ndiswrapper-gtk. I get a Windows Wireless Drivers in my Administration menu, and I was able to get it to read the Windows 7 .inf file. The .inf for XP does not work. It adds it and the driver appears in the list with "Hardware: present". I set up the wireless connection information (ESSID and WPA2-Personal key). Problem: I don't see the network manager icon in the top right of the screen. I managed to manually start it manually using sudo services network-manager restart but it shows no connections in the menu, saying that there's nothing to manage. In my /etc/network/interfaces file I have an entry for the loopback and the standard two-liner for eth0 with dhcp. From memory, something like: iface eth0 auto eth0 dhcp I had read somewhere that 10.10 would have standard support for my wireless adapter (TL-WN7200ND) but that seems not to be the case. However, I don't ever remember having the network-manager icon in the top-right and it does not auto-start at the moment. This was originally an Ubuntu 9.10 install that I've upgraded over time. I also used to use pppoeconf to connect to the net, which might affect the /etc/network/interfaces file?

• Can TP-Link router make phone calls?

  - by Umair Ashraf

  I have a TP-Link router with DSL service provided by a local company which serves it over the landline phone. My landline cord is plugged into an ethernet router which is then plugged into TP-Link wireless router. I can access internet with this wireless router all over my home with all computers. Landline Cord [into] Ethernet Router [into] TP-Link Wireless Router [air] Computers I would add that landline cord is also into a phone device which I use to make calls and that's not cordless. Now I am accessing internet via WiFi on my laptop and want to ask if is this possible to make landline calls via this same computer I am surfing internet through? What I am asking it to a dial-up via TP-Link router that goes through landline. You see the landline cord is the actual data gateway and is also used to make calls. So it can simultaneously send Data and Voice over the same wire.
