• LinkSys WRT54GL + AM200 in half-bridge mode - UK setup guide recommendations?

  - by Peter Mounce

  Crossposted from here I am basically looking for a good guide on how to set up my home network with this set of hardware. I need: Dynamic DNS Firewall + port-forwarding VPN Wake-on-LAN from outside firewall VOIP would be nice QoS would be nice (make torrents take lower priority to other services when those other services are happening) DHCP Wireless + WPA2 security Ability to play multiplayer computer games I am not a networking or computing neophyte, but the last time I messed with network gear was a few years ago, so am needing to dust off knowledge I kinda half have. I have read that I should be wanting to set up the AM200 in half-bridge mode, so that the WRT54GL gets the WAN IP - this sounds like a good idea, but I'd still like to be advised. I have read that the dd-wrt firmware will meet my needs (though I gather I'll need the vpn-specific build, which appears to preclude supporting VOIP), but I'm not wedded to using it. I live in the UK and my ISP supplies me with: a block of 8 static IPs, of which 5 are usable to me a PPPoA ADSL2+ connection

• External display resolution issue

  - by Steven

  I'm new to Ubuntu. I've 'dabbled' in the past but Windows was annoying me too much so I finally made the change. One thing I use my laptop for is outputting the screen onto an external monitor. In Windows this usually works fine (but when there is an issue, it's a pain to resolve and has crashed my computer on many occasions). In Ubuntu it's a very simple case of "plug and play" because it displays the content immediately with no major problems. However, I can only alter the resolution of the external display to 4:3 formats, whereas the external monitor is 16:9, so the picture is stretched. In Windows there's loads of resolutions to choose from. If I disable the laptop's screen, it still doesn't allow me to display the correct resolution externally (on VGA). Further to that, if I close the laptop it keeps the external screen as it is, but when I reopen the laptop, the laptop screen doesn't turn back on until I restart. If it's a video I am watching, I can use VLC to alter the aspect ratio so the video looks fine, but it's quite an annoying work around. I used terminal to find my graphics controller, which is "Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller [8086:2a42] (rev 07)" (not great, I know... the laptop was a free gift with my mobile!) Any idea of how I can get the resolution on the external monitor to be correct?

• Files not accessible

  - by gokul

  My system is running on a pc with C:\ Drive out of space. So I tried to delete some file and clean up to get more space. I found that the %Temp% {C:\Users\Username\AppData\Local\Temp} takes lots of space and tried to delete files in it. But when I open it , it alerted me with the message C:\Users\Username\AppData\Local\Temp is not accessible The file or directory is corrupted and unreadable? What to do? Is deleting files from Temp harmful to computer?

• Windows diagnostic tools

  - by Tathagata

  I just joined a small computer lab which basically uses all Windows boxes and a few Windows Sever 2003. Coming from a *nix background I am missing all the nice tools that we have for diagnosis and troubleshooting. My question is what are the safe, free (not terribly concerned if it is like beer or freedom -both acceptable) tools out there that Windows system admins use for their day to day troubleshooting (network, applications, servers etc). I am aware of the tools that come with Windows (and their limited capabilites) - so my query is with what do you fill in your arsenal? (may be a list of win versions of tools that come in standard linux distros)

• Why does the task pictogram flashes instead of opening the program?

  - by fredley

  Sometimes, when I select a click a program on the Windows 7 taskbar it won't appear (it doesn't gain focus and remains behind other open windows), and the icon will flash and turn orange. This happens reasonably frequently, and I've had it happen on two separate Windows installs on different machines. It just happened now and the only programs I have with active windows are Chrome, WMP and Explorer (2). It happened when I clicked Explorer. Once this has happened to one window, it affects all windows, and the only way I can switch between programs is by finding the window manually or using Windows+Tab. The only way I've come across to get the computer to snap out of this annoying behaviour is to restart the machine. Is there a way of stopping it? Edit Here's a video of it happening: http://www.youtube.com/watch?v=P12OxKK0kM4

• HP Officejet 7410 AIO: Scanning/copying output is a solid black field

  - by William

  I recently tried to breathe some life back into an old Officejet 7410 for my parents. The printing is fine, but the scanning and the copying respectively produce images and copies that are mostly solid black, except for the first inch or so from the top of the original page. At first I thought this was a bulb problem, so I replaced it. Unfortunately, the problematic behavior is still there. I've tried resetting to factory defaults. Still no improvement. I don't think this is related to my OS or drivers, since the copying is also affected even when the connected computer is powered off. So... my question(s): What is the cause of this bad behavior? Given that, can my Officejet be repaired? If so, how? Thanks in advance.

• Broadcomm WIDCOMM A2DP Quality Adjustment

  - by snicker

  So I got a sweet pair of bluetooth A2DP headphones for a sweet, sweet price (Motorola A805, if you were wondering). They sound great paired with an iPhone. However, when I pair with a computer using the latest and greatest WIDCOMM drivers, the quality is quite poor, almost un-listenable... clicking, popping, scratching. The remedy on one machine was using BlueSoleil, another bluetooth stack, as there is an adjustment for the Bitpool settings that allow you to jack the quality up. Sounds great. However, the bluetooth chipset in my other machine is not supported by BlueSoleil... so I'm stuck with the WIDCOMM stack. So the question is... Is there an undocumented way to turn up the quality for A2DP in the WIDCOMM drivers? first question on SU, usually lurking on SO.. =]

• How can I get my Sapphire Radeon 7850 to output in "1080p"?

  - by Fr33dan

  I have a Radeon 7850 connected to a Vizio 3D compatible TV. The TV has a function to parse and display SBS encoded content. On my old graphics card (a Radeon 5770) I just had to select the 1080p option in the catalyst control center. In this mode my TV reported the output mode as "1080p", with the new card the TV reports "1920x1080". I cannot figure out what the difference in between the 2 signals but the "1920x1080" cannot be switched into 3D mode by the TV. Weirdly, before windows starts the (in the Bios and so forth) the computer outputs in "1080p" so I know the card is capable of it. As soon as the blue login screen comes up though it changes back to the "1920x1080". I've tried everthing I can think of. Updated my drivers from 13.3b3 to 13.4, then even tried the 13.5 beta (Which I'm still on this moment). Tried all the "optimized" HD settings in catalyst, even the 720p modes show the resolution from the TV and not the "720p" (which it used to do on the old card when I had to lower the resolution of games)

• How do I log which process is deleting a file on Windows XP?

  - by Jordan Milne

  I'm having an issue with a file getting deleted seemingly randomly throughout the day. The vendor of the software whose file is getting deleete says that another piece of software installed on the computer is deleting it, while the other software's vendor says the opposite. I've tried using Process Monitor so I can pinpoint exactly what's deleting it, but even when filtered specifically to that file, createfile operations are being triggered a few times a second, and I can't seem to filter it to deletions specifically. Is there a tool or script I can use to specifically monitor deletion attempts on a single file?

  I am using Windows 7 as the host. And xp as guest. I've already check out this site: http://forums.virtualbox.org/viewtopic.php?f=3&t=17232 But the info is not complete.

• Power Supply Not Working?

  - by Mr.Glass

  So I recently made some purchases for a new computer including: Motherboard: Gigabyte GA-EP45-UD3R CPU : Intel Core2Quad 2.66Ghz Power Supply: Antec Basiq 500w UPDATE: I got the Power Supply working, the motherboard's lights come on, the video card fan spins, BUT the CPU fan does NOT spin and there is no video. Whats the possibility of lacking power? In the mobo guide it says the use of a power supply providing a 2x4 12V connector is recommended (I do not have this connector) by the CPU manufacturer when using an Intel Extreme Edition (I'm using Core2Quad) UPDATE: Got it working, intstalling windows 7 now. THANKS GUYS!!

• How to make a quiet laptop?

  - by psihodelia

  Most modern laptops have very noisy fans. I am looking for a quiet laptop or a small stationary computer which has all its hardware built in a display. Most tasks will be PDF/docs processing, real-time audio processing, web-surfing and Skype video chats. Certainly, there is no any fan-less model today; but maybe some of the existed laptops do not switch on their fans so often or implement different solutions? For example, an iPad has no fan at all and it is fast enough for my needs, but it has no normal operating system, so I can't use it for anything but audio chats and web-surfing. Or maybe I can buy a laptop and tweak it to make it absolutely noiseless? Can you recommend any solution please?

• i[Pod|Phone|Pad|*] backups in iTunes

  - by Maroloccio

  iTunes <- iPhone. At sync time, a back-up is performed. Which data is included, which data is not? i.e. are songs (potentially redundant) backed-up so that a computer ends up having both the source file on the filesystem and the copy within the device back-up? Is anything on the iPhone filesystem not backed up? (i.e. on a Mac using Time Machine, some files are excluded from the back-up even if not all of them can be recreated upon restore - I lost my postfix config this way..)

• Lock Windows keyboard and mouse but still display screen normally

  - by Stephen Lacy

  I'm using windows 7, I have a dual monitor display. It displays important information related to the business, I'd rather that random users that walk in can't just walk over to it and start using the computer with the same access rights as the user the monitoring software is running as. What I would like is if any time someone presses a button on the keyboard including alt-ctrl-delete all that would appear is a dialog asking for a password. Then I can click cancel and it will return to showing the data I want displayed. ClearLock doesn't work I tried it btw

• Is the 4-pin PSU connector required? (Trying to connect a PSU to a mini case.)

  - by Geeks On Hugs

  I am trying to build a computer, placing an ASUS P8H67-I DELUXE in a custom retro C64 case. The case is an extra small form factor which can accomodate the Mini ITX board, but requires an external power supply, similar to the power-bricks that laptops use. I am looking at different power supplies and like these, but cannot figure out whether/how to power this system because they provide a 24-pin connector, but the motherboard has a 4-pin connector as well. Is the 4-pin connector optional or is it required? If it is required, how can I provide power for this system?

• Photo transfer problems from camera

  - by warkior

  We have a digital camera (Cannon SX130 IS) which we often connect to the Ubuntu 12.10 desktop via USB in order to download the images. In past flavours of Linux (Mint 12 was most recent) it worked fine, however since upgrading to Ubuntu 12.10, the process fails after downloading a small number of the images. I can view the images which will be transferred in the preview window, and I can browse the camera file system to download the images manually, but if I just drag/drop the images over from camera to desktop, it freezes after 5-6 are copied over. I've been able to get around the problem by only copying 3-4 at a time, but when you have 100+ images to transfer, that gets really frustrating. Any advice on where I could start looking for answers, or how I could diagnose the source of the problem further? We have also had some issues with WireLess USB mice though it may not be related. I'm hoping my USB controller in the computer isn't dying... it's not that old. Also, it seems to work much better under Windows.

• How do I remove office 2008 from OS X when the "Remove Office" tool says no version of office are in

  - by kbyrd

  I have Office 2008 for OS X through Microsoft's HUP (Home Use Program). I want to reinstall, so I need to first remove it. For Office on OS X, Microsoft provides a binary called "/Applications/Microsoft Office 2008/Additional Tools/Remove Office/Remove Office". When I run it, it says it can't find any versions of office on my computer and won't do anything. I know MS-Office for Mac puts many different components in various places all over the system and not just within it's own applications folder, so how to I successfully remove Office so I can re-install?

• IPSec on Domain Controllers and Trusted Domains

  I am looking at configuring IPSec as follows: Isolation Request authentication for inbound and outbound connections Computer and user (Kerberos V5) I am looking to do a blanket deployment across all servers and domain controllers. Workstations I will leave as not set. What impact in terms of the domain controllers with the 2-way forest trust do think I would see? Should I exclude the IP addresses of the trusted domain controllers? I don't want to stop communication between the current and trusted forest, however I do want IPsec to be used within the current forest on all servers. The trusted forest is running 2008 R2 and the current forest is 2012 R2.

• 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 Home Premium - Unable to View Chinese Characters Properly

  - by David

  Is there a proper and permanent fix that will restore the display of Chinese Characters on a Windows 7 Home Premium Laptop computer? This problem has been occurring frequently now and a simple reboot no longer does the trick. The square boxes viewed on many applications and websites has been constantly bothering me and I wish to fix it asap. I have done a lot of research on it but have not been successful. Many responses were to install the language packs for Windows 7 Ultimate Users which apparently is not my case or to configure the "Region and Language" settings of the Control Panel, changing the system locale. Does anyone have any suggestions? All would be appreciated!
