• Windows 7 file sharing password protecting or making stuff available to just me

  - by Carbonara

  Even with the new Homegroup feature I'm still finding the way Windows deals with folder sharing utterly baffling. Here's what I want to do. I have two computers, a PC Desktop and a laptop. I also live in a shared flat with other computer users. I have set up a Homegroup and a Workgroup on the desktop and joined them on the laptop and in the home group I have shared video, music and pictures. This is so that anyone on the network can view pictures and listen to music etc. But I want my Documents folder from my desktop to only be available to me on my laptop and not to anyone else that may be on the network. The Homegroup only allows (from what I can gather from the baffling array of options) sharing with everyone or no one. Is it possible to only allow the laptop to access the documents folder on the desktop? The user name and password are the same on both computers.

• Ubuntu One has high CPU usage but no syncing

  - by Peter

  over the weekend I updated my computer to Windows 8. So far Ubuntu One was running smoothly, but ever since the update (clean, new install) Ubuntu doesn't sync any more. In Windows 7 it would start to sync at full internet speed as soon as I drop a file. But now in Windows 8, as soon as I drop a new file into the Ubuntu One folder, CPU usage goes up to about 50 % and no network traffic occurs. This stays like that for a couple of minutes, CPU usage goes back to normal and then the client says that all is in sync - which isn't true. Is it too early for Windows 8? Do others have the same problem or is there something I can do about it? I try a couple of different things, and realized that if the file size is 20 MB the files get uploaded. The original file was 1.5 GB. I also didn't work with 200, 100 and 50 MB large files. But even with 20 MB large files, the upload is very slow and not steady. The log give plenty of this error: - twisted - ERROR - Failure: exceptions.TypeError About which I don't know the meaning. By the way, the account works just fine on the Ubuntu 12.04 partition. Any help is greatly appreciated. -Peter

• Windows Advanced Firewall certificate based IPSEC

  - by Tim Brigham

  I'm working on migrating from using IPSEC settings stored under the 'IP Security Policies on Active Directory' to using the 'Windows Firewall with Advanced Security' for my 2008+ boxes. I have successfully been able to get this set up using Kerberos authentication, however my openswan implementation on my Linux boxes is using certificates. Whenever I try changing the authentication method to computer certificate (using RSA and my root CA) the connection is bombing out. I've made this change at both a connection request policy and on the IPSEC settings on the root Windows Firewall with Advanced Security node. The windows event log shows the authentication request is taking place but failing negotiating a mode. What am I missing here?

• Unable to extend desktop

  - by CSharperWithJava

  I'm trying to hook up my TV to my computer as a gaming/multimedia center but I'm having troubles setting it up. I have a custom built machine running Windows 7 RC. It has an ATI Radeon 4800 video card with 2 dvi output and 1 S-video output. I have an s-video to composite adapter that connects to my tv. (It's an old TV with only Cable, composite, and s-video connections). I can switch the desktop to my TV without a problem, but I can't duplicate or extend my desktop onto it. I've installed the latest drivers and Catalyst Control Center, but it won't let it work any more readily than Windows would. Any suggestions? Would using an s-video cable instead of the adapter change anything? (The only reason I use the adapter is because it came with the graphics card) (Edit) I installed the latest drivers and I can now duplicate the screen (show on one monitor and on the TV), but I still can't extend the desktop.

• Third-party Information Screen Opening Blank

  - by Jacob

  I'm working with a client who is trying to use our software, which accesses information (sends & receives) from a third-party website. When this client tries to access these pages, a window opens, as expected, but is completely blank and no error message is received. This is the first time I've seen this with many other clients successfully using this product, which leads me to believe that it has something to do with the settings on the computer somewhere, but cannot figure out what might be happening. Windows Server 2003 R2, Standard Edition, Service Pack 2. Firewall is already off. Tried AVG on & temporarily disabled.

• How to Manage and Use LVM (Logical Volume Management) in Ubuntu

  - by Justin Garrison

  In our previous article we told you what LVM is and what you may want to use it for, and today we are going to walk you through some of the key management tools of LVM so you will be confident when setting up or expanding your installation. As stated before, LVM is a abstraction layer between your operating system and physical hard drives. What that means is your physical hard drives and partitions are no longer tied to the hard drives and partitions they reside on. Rather, the hard drives and partitions that your operating system sees can be any number of separate hard drives pooled together or in a software RAID Latest Features How-To Geek ETC Inspire Geek Love with These Hilarious Geek Valentines How to Integrate Dropbox with Pages, Keynote, and Numbers on iPad RGB?

• Motherboard RAM question.

  - by winterwindz

  Firstly I'm new at this. Not a very computer-ish person. So I very much apologize if this is not the right place, but here it goes.. My Motherboard is an Asus P5LD2-SE. I'm running in Win 7 Ultimate 32-bit(x86) OS, 1GB RAM (2x512 MB). I'm planning to upgrade my OS to 64-bit and because I know my Motherboard is a dual-channel, I bought a dual-channel 2 GB RAM (2 pcs). My question is; am I still able use my old RAM ones, since it is 4 slots..? Which in the end will show 5GB. Is it possible? Thank you for your time. =)

• How to schedule time-of-day upgrades

  - by Richard

  Hello, I'm responsible for about 30 Ubuntu computers at a private K-8 school. We have only a 3Mbps internet connection serving the entire campus, and I would like to ensure that updates are done in the middle of the night - so that daytime tasks are not slowed down. I'm using Ubuntu 10.04, and have set all computers to download and install security updates via the update manager. I have also installed cron-apt, and modified the config file to stagger the start times of the upgrades from about 10pm to 4am local time. HOWEVER - this morning I arrived at the school at 7:30am and all the computers were busy downloading a large security based update. Needless to say, all internet activity was slowed to a crawl (for the next 2 hours), and the computer users were very very upset. This was the event I'm trying so hard to prevent. It seems that my scheme to ensure middle of the night downloads failed, and I'm not sure why. I've also tried some schemes using unattended-upgrades & crontab, but there always seemed to be something scheduling upgrades to occur in addition to the ones I try to force at middle of the night. Is there a sure fire way to absolutely positively guarantee that updates will occur only at one specific time? It would be nice if the update manager just had a drop down menu to specify a designated time. Thanks in advance for any help you can give me.

• Changing keyboard layout for login screen on Mac OS X

  - by R.A

  I have a Mac Mini with Mac OS X Lion. Basically I am a developer and practiced coding with DVORAK keyboards. So I changed my keyboard layout to DVORAK and I'm working with it. I'm using the admin user on my Mac Mini. When I restart my computer, during login, the layout is changed to QWERTY and it's hard to type the password. It happens only for the admin user though. If I create the another user and set the layout as DVORAK and restart, that user has the DVORAK keyboard for login. Note: I have a QWERTY keyboard, I'm only changing the layout in the keyboard preferences. So, to summarize, how can I get the DVORAK keyboard layout for the admin login as well?

• Windows 7 just restarts, no BSOD, shows "Event ID 14 volsnap"

  - by Mdc007

  My Windows 7 just restarts without giving me a BSOD. When it reboots, it will hang sometimes and you have to let it rest. Sometimes it will print a message saying that Hal.dll is missing or corrupt. When it does restart I can't run a backup or a clone drive – it comes up with constant errors. I tried to run chkdsk – it says everything's clean. What is really puzzling is SyncToy on a different drive hangs half way through and won't run either. Machine: OCZ SSD Agility 2 for C drive SATA HDD for programs, documents on D drive MSI AMD 880 chipset Event viewer says something about critical power failure I/O operations and "Event ID 14 volsnap" – but that is just telling me the computer powered off which I already know.

• SQL Server Migration Assistant for Oracle problem

  - by Paul

  I've recently installed SSMA on my computer and after connecting to both the Oracle instance (which holds the database to be converted) and the SQL Server. I've mapped the needed schemas from oracle to mssql. The problem is that when i click on the report button for the assessment report there's an error popping up: Assesment Error : Nothing to Process The output window states: Starting conversion... Analyzing metadata... Conversion finished with 0 errors, 0 warnings, and 0 informational messages. There is nothing to process. Has anyone got experience with SSMA. I can't figure out what I am doing wrong. Thank you.

• NMap 6.01

  - by TATWORTH

  NMap 6.01 has been released at http://nmap.org/download.html"Nmap ("Network Mapper") is a free and open source (license) utility for network discovery and security auditing. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. It was designed to rapidly scan large networks, but works fine against single hosts. Nmap runs on all major computer operating systems, and official binary packages are available for Linux, Windows, and Mac OS X. In addition to the classic command-line Nmap executable, the Nmap suite includes an advanced GUI and results viewer (Zenmap), a flexible data transfer, redirection, and debugging tool (Ncat), a utility for comparing scan results (Ndiff), and a packet generation and response analysis tool (Nping)."Home page is at http://nmap.org/  Nmap is free to download and use. You can download the source and compile it yourself if you so require.

• Simulating network latency for localhost connection on Windows 7

  - by nitro2k01

  I need to simulate network latency to a program running on the local computer, connecting to a local service. Thus far I have tried dummynet (a windows build of ipfw) which I got working after some trial and error. While it generally works, I can't seem to get it to filter localhost traffic. Even after adding a rule from any to any which affects external traffic, this makes no difference for local connections. I would appreciate if anyone knows how to simulate local latency using dummynet or a different tool. The tool should be able to simulate latency generically in IP packets, (TCP and UDP) and not be protocol specific.

• Uninstalled Ubuntu, no GRLDR?

  - by user32965

  So I'm a big fat idiot. I installed Ubuntu 11.04 on my school's laptop, and here's come the time that I have to turn it back in. I wrote GRUB to the Master Boot Record, thinking it wasn't going to be permanent. So, fast forward to yesterday. I decided to hell with this, and popped in my Windows 7 CD, deleted the whole partition, formatted to NTFS, and installed Windows 7 on it. I'm surfing the web and my computer overheats [totally typical] I boot up, and get this: Try (hd0,0): FAT32: No GRLDR Try (hd0,1): invalid or null Try (hd0,2): invalid or null Try (hd0,3): invalid or null Try (hd1,0): NTFS5: No grldr Try (hd1,1): invalid or null Try (hd1,2): invalid or null Try (hd1,3): invalid or null Cannot find GRLDR. Press space bar to hold the screen, any other key to boot previous MBR... Timeout: 5 The timeout part just counts down to 0 from 5. I need to turn in this thing before tomorrow, please please please can someone help me out?

• suddenly can't connect to windows 7 pc from xbmc

  - by Damon

  I have xbmc installed on a softmodded classic xbox and all of a sudden I cannot connect to the shared folders on my windows 7 PC. Well, it can connect but it wants a username and password, but none exist on my computer. It's been several weeks since I last used it, but it was working fine then! and no particular changes I can think of aside from I guess a few windows updates. I've seen reference online to windows live essentials causing issues with file sharing, but I don't even have that installed. And I made sure to tick 'turn off password protected sharing' in my advanced network setup. I had the guest account turned off and working fine before, and tried turning it on but no luck. I can access my shared folders fine from other Computers and a ps3. I've read a couple threads of similar situations on various folders and none of their solutions have worked.

• Get-QADComputer -LdapFilter & NOT operator

• how to troubleshoot shutdown problems in windows 7

  - by Ieyasu Sawada

  I have a desktop with windows 7 ultimate installed. Whenever I shut it down from the start button. The text that says that it is logging off and shutting down is present and the monitor blacks out and says no signal. But the lights in the RAM is still on and all the fans in the desktop is still spinning. Why is that? It seems like its not shutting down completely. I have also got disk problems lately. Event id 175 and 50. Which I think is caused by the computer not shutting down completely. How do I troubleshoot this one? Feel free to ask if you need more details, thanks.

• Ubuntu update deleted entries from grub

  - by Kevin

  My computer currently has Fedora, Ubuntu, and Windows installed. I just updated Ubuntu 12.04, and on restarting, the Fedora entry was gone from GRUB. Ubuntu and Windows remained, though. I have looked at these threads: Fedora login gone after Ubuntu updates on a dual boot http://forums.fedoraforum.org/showthread.php?t=279221 GRUB's menu.lst deleted after a kernel update However, I cannot figure out how to mount the drive as suggested. It does not appear in the list on the left side of nautilus as shown in the links above. I also tried running the following as suggested above: sudo grub-install /dev/sdX sudo update-grub But this gave scary errors: /usr/sbin/grub-setup: warn: Attempting to install GRUB to a partitionless disk or to a partition. This is a BAD idea.. /usr/sbin/grub-setup: warn: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE and their use is discouraged.. /usr/sbin/grub-setup: error: will not proceed with blocklists. The highlighted drive below is where Fedora lives. Thanks for any help reversing Ubuntu's decision to delete this from GRUB.

• Breaking up classes and methods into smaller units

  - by micahhoover

  During code reviews a couple devs have recommended I break up my methods into smaller methods. Their justification was (1) increased readability and (2) the back trace that comes back from production showing the method name is more specific to the line of code that failed. There may have also been some colorful words about functional programming. Additionally I think I may have failed an interview a while back because I didn't give an acceptable answer about when to break things up. My inclination is that when I see a bunch of methods in a class or across a bunch of files, it isn't clear to me how they flow together, and how many times each one gets called. I don't really have a good feel for the linearity of it as quickly just by eye-balling it. The other thing is a lot of people seem to place a premium of organization over content (e.g. 'Look at how organized my sock drawer is!' Me: 'Overall, I think I can get to my socks faster if you count the time it took to organize them'). Our business requirements are not very stable. I'm afraid that if the classes/methods are very granular it will take longer to refactor to requirement changes. I'm not sure how much of a factor this should be. Anyway, computer science is part art / part science, but I'm not sure how much this applies to this issue.

• Windows Vista: TCP/IP stack is smashed, how to reinstall the LAN-Devices?

  - by Ice

  the TCP/IP stack is smashed, thats why no LAN-Connections are running. I want to download the LAN drivers from another computer and uninstall and reinstall the LAN devices on this system. Hopefully that should recreate the stack. But what to download? What uninstall? How to install? Windows Vista is protected against such changes, so how to achieve that job? please help. Update per 2011-03-11: I found all the tipps and hints about "TCP/IP Repair, LSP Fix, and WinSock Fix" according to windows vista but nothing helped to bring back network access. What can i do as next step or which opportunities are left?

• Compressed disk image on Linux

  - by Aaron Digulla

  I just got my new computer with a much bigger harddisk. I think I copied all important files over but just to be sure, I'd like to keep a disk image of my old disk. To save space, I'd like to compress it but I didn't find an option to mount a compressed image. My goals: Result must be easy to access No need to decompress the whole thing before I can access anything Files should be quick to locate - no TAR/CPIO archive Necessary space should be less than just copying the files over So ideally, I'm looking for a read-only, compressed file system which I can create in a file and which grows automatically.

• Why did the web win the space of remote applications and X not?

  - by Martin Josefsson

  The X Window System is 25 years old, it had it's birthday yesterday (on the 15'th). As you probably are aware of, one of it's most important features is the separation of the server side and the client side in a way that neither Microsoft's, Apples or Wayland's windowing systems have. Back in the days (sorry for the ambiguous phrasing) many believed X would dominate over other ways to make windows because of this separation of server and client, allowing the application to be ran on a server somewhere else while the user clicks and types on her own computer at home. This use obviously still exists, but is marginalized at best. When we write and use programs that run on a server we almost always use the web with it's html/css/js. Why did the web win, and X not? The technologies used for the web (said html/css/js) are a mess. Combined with all the back-end-frameworks (Rails, Django and all) it really is a jungle to navigate thru. Still the web thrives with creativity and progress, while remote X apps do not.

• Strange sound from Laptop, Microphone, Speakers or Soundcard?

  - by David Schilling

  I have recently purchased a second hand computer. There didn't seem to be anything wrong with it on purchasing, however recently I have noticed a small issue. Any time I play sound or listen through my headphones, I can hear what seems to be the CPU working (ie when beginning a new task, there is a small crackling). Also if I tap my laptop I can hear the sound louder, as if it is being picked up by the mic and then playing that sound in real time through the speakers or headphones. I have tried reading other topics but cannot find an answer to this question. These are the specs I am running on; Windows 7 Home Premium 32bit Pentium Dual Core CPU T4300 @ 2.10Ghz 2.10Ghz I hope someone can help me with this issue, it would be much appreciated.

• Preventing SSH RSA host key warnings for change of key vs IP address

  - by Adam M-W

  I have a network with DHCP enabled, and also a computer that dual boots operating systems and has different SSH keys on each (and yes, I would like to keep different keys on each rather than copying the same identity/private key to each). Because the IP address does not change between operating systems because the MAC address is the same, when connecting to ssh, even when not using the IP address but the hostname via DNS/mDNS, I get the warning: Warning: the RSA host key for 'hostname' differs from the key for the IP address '192.168.1.172' Offending key for IP in /Users/user/.ssh/known_hosts:37 Matching host key in /Users/user/.ssh/known_hosts:38 Are you sure you want to continue connecting (yes/no)? How can I surpress the warning when the hostname differs from the IP address for that hostname, but retain the ability to check host keys are the same for each hostname? (each OS has a unique hostname)

Then I can click cancel and it will return to showing the data I want displayed. ClearLock doesn't work I tried it btw
