• Broadcom 4312 wireless not working on an HP dv6-1245 DX

  - by vitalie

  I have installed Ubuntu 10.04 on my HP dv6-1245 dx notebook and I do not have any wifi (it worked perfectly in windows vista and 7). I have followed a lot of instructions found on net but still not able to get Internet.

• Can a power failure or forceful shutdown damage hardware?

  - by Vilx-

  In an unrelated Internet forum I got into a discussion about hardware damage from forceful shutdowns (holding the power button for 5 seconds) and power failures. I was in the opinion that normal PC hardware does not suffer from this - after all, it's not much different than what they experience under a standard shutdown. But another person thought that it could do physical harm to the hard drive and possibly other components as well. He also said that the journaling features of filesystems are useless in face of power failures and were intended to help mitigate damage from system crashes. Now... I think this is nonsense, but then again I lack the experience and knowledge to say it with certainty. Perhaps someone else is more knowledgeable in this area and can shed light on this burning issue? :)

• How to get Windows 7 to automatically connect to an ad-hoc network?

  - by George Edison

  I have two machines - one is running Ubuntu 12.04 64-bit and the other is running Windows 7 Starter Edition (32-bit). The Ubuntu machine is connected to the Internet via the eth0 interface. That machine also has a wireless network interface (wlan0) that is currently functioning as an ad-hoc network. I can connect to the ad-hoc network just fine with the Windows machine but each time I wish to do so, I must manually initiate the connection and enter the password. Is there some way to instruct Windows to automatically connect to this network (an option I have for standard wireless networks but not ad-hoc networks)?

• debian modem problems !!!

  - by Raafat

  hay there guys ... I'm a new Debian user, it looks like a very good choice 4 me, every thing is stable, free and easy to use. the problem is, I'm using my modem to establish a dial up connection to the internet (ppp) (a very old stupid way I'm forced to use for now), and using the KPPP application to do that, and nothing is working properly for me. it seems like it didn't recognize my modem or something. i already tried to make a few stuff, and now i know my modem is on /dev/tty0, so i made a link for that on /dev/modem, and query the modem using KPPP and it responded with something like: Ati : Ati0: Ati1: ... ... Ati7: with a textBox to fill up in front of each one of thees Atis, and now, when i press connect on kppp, it says modem ready, and that's it. BTW, my modem is MDC AC'97 any suggestions pleas ....

• Recovering drivers from previous installation?

  - by Walkerneo

  Yesterday I bought a new computer and I've been setting it up since this morning. The hard drive came with windows 7 home premium (x64) installed, but I decided to instead install windows 7 ultimate (x64) - this is what I'm currently using. Unfortunately, there were some drivers that were installed that I need in this installation. I only notice because the computer doesn't have the ethernet drivers, so I'm only able to connect to the internet via wireless. There are other drivers missing as well, but I'm not yet seeing the effects. I still have the Windows.old folder with the previous installation, which has the drivers. Is there any way to copy the necessary ones over? I tried the options for updating driver software through device manager with the path set to System32\drivers of the old installation, but it didn't find anything.

• Cablemodem frequent connection loss

  - by LVDave

  I have a Linksys BEFCMU10 cablemodem and a WRT54GL router with Tomato 1.27 firmware on Cox cable. My question is this: I get what seems to be random disconnects from the internet, where the cable modem lights are still normal, but I can connect nowhere, either via a url or an ip address. At the same time these disconnects are happening, I can go to the router's Tomato management webpage, and release/renew my external IP address from Cox's DHCP server. I've had Cox look at the signal levels on the cable modem, and they say they look fine. What brings back the modem, for sometimes as long as 17 days, is several power-cycles of the modem. I don't understand the underlying cable modem technology too well, but I do know that if I'm able to release/renew the DHCP-provided WAN address, I'd expect that the cable modem was working ok... Anybody have any ideas??

• EC2 custom topology

  - by Methos

  Is there any way to create a desired topology of EC2 instances? For example, can I create a 3 node topology of nodes A, B, C where C gets the public IP address and B and A are connected to it. Something like: Internet <-- C <-- B <-- A B and A only get private IP addresses and there is no way for the traffic to reach A before hitting B and C. This means I can install whatever I want to install on C and B to filter, cache etc. I'm going through EC2 documentation but so far I have not seen anything that talks about it. I will really appreciate if anyone knows how to do this on EC2

• How do I configure custom routes when an interface is configured?

  - by ManicDee

  Other Superuser questions have addressed the issue of adding custom routes to access e.g.: multiple networks of a corporate network through one interface, while accessing the Internet through another interface. So assuming that I have a script to add specific routes when en0 is configured, and a separate script to add specific routes when en1 is configured, is there some way I can trigger those scripts to run automatically when Mac OS X/Darwin starts and configures those interfaces? Back in my Linux days, it was possible to add an option in /etc/network/interfaces along the lines of: iface eth0 inet dhcp up /usr/local/sbin/eth0-routes-up Is there something similar for Mac OS X?

• Streamline Active Directory account creation via automated web site

  - by SteveM82

  In my company we have high employee turnover, and hence our helpdesk receives about a dozen requests per week for new Active Directory accounts. Currently, we receive these requests simply via e-mail or voice-mail, and rarely do we have all of the information necessary to create the account. I would like to find a web application that can be used by a manager or supervisor to formalize the requests they make for AD accounts for new employees under their command. Ideally, the application would prompt for all of necessary information, and allow the helpdesk to review the requests and approve or deny each one. If approved, the application would take care of creating the account and send an e-mail to the manager. I have found several application on the Internet that handle self-service account management (i.e., password resets or update contact info), which is also nice to have, but nothing that streamlines the new account request and creation part. Can anyone make suggestions on such an application? Thanks.

• Window borders missing - gtk-window-decorator segmentation fault

  - by Balakrshnan Ramakrishnan

  I have been using Ubuntu for about 1 year now and I got a problem just two days ago. Suddenly I started experiencing a problem with the window borders (title bar with close, maximize, and minimize buttons). The problem : The window borders disappear I run "gtk-window-decorator --replace" For like 20 seconds everything is back to normal But it again returns to the problem. I searched over the Internet and found that my problem is similar to what is specified in this bug report: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/814091 This bug report says that the "fix released". I updated everything using the Update Manager, but still the problem remains. Can anyone let me know whether the problem is fixed? If yes, can you please let me know how to do it? I have already tried normal replace/reset commands like unity --reset unity --replace compiz --replace The "window borders" plugin is on in CCSM (CompizConfig Settings Manager) and it points to "gtk-window-decorator". I use Ubuntu 11.10 on an Intel Core2Duo T6500 with AMD Mobility Radeon HD 4300 graphics card. If you need more information, please let me know.

• Web server (IIS) and database mirroring (Postgresql)

  - by Timka

  Recently our web-server crashed and we had to recover everything from a backup which took the whole day(totally unacceptable in our business). So my question is, how can I create a complete mirror of the server that I can use (switch dns to) in case the same disaster happens in the future? Our main server is on Amazon with Windows 2008/IIS + Postgresql 9.1. I was thinking on creating the same server on a different location as a complete mirror with the database replication. But I'm not sure how to implement IIS instance mirroring over the internet... So my question is, how can I create a complete mirror of the server that I can use (switch dns to) in case the same disaster happens in the future?

• Which browser does my computer use to open a Web page? [on hold]

  - by msh210

  I know little about networking the Internet, but, from what I understand, it works — very approximately — as follows: I, sitting at the computer example.com, send a message saying, roughly, "get http://s.tk" to my ISP, which passes the message along, eventually to the machine at s.tk. The s.tk machine gets "example.comhas sent 'gethttp://s.tk'", so sendssomefileto its ISP which passes the file along, eventually to the machine atexample.com`. When the file gets back to example.com, my computer, how does my computer know what to do with it? I'm sure the headers (or something else) indicate it's a Web page rather than, say, a Usenet post — that's not my question. My question is: how does it know whether to display the Web page in my open Opera window or my open Firefox window, or my other open Firefox window, or, heck, to open a new browser instance?

• What does S in linux file properties mean?

  - by penguin

  I'm creating directories and changing the permissions of them in perl with the following code: umask 0000; mkdir $path, 0770; chown $userid, $groupid, $path; Now when I do ls -l on a directory I've just created, they are as follows: drwxrws--- 2 user group 4096 Nov 3 15:34 test1 I notice for the group permissions, there's an s instead of x. Even if I chmod manually to remove all permissions for the user and group ("chmod g=" and "chmod u=", it's still there: d-----S--- 2 user group 4096 Nov 3 15:36 test2 The internet suggests S means everything in the folder is run as su or something? I don't quite understand what it means but I figure I should understand seeing as these are webroots so if there's a security implication, I ought to be aware of it. Many thanks for your help!

• How do I increase my home's bandwidth?

  - by Derek

  I just mistakingly posted this on Stack Exchange but don't know how to delete it... Anyway, I was thinking of building a home server to use instead of renting a VPS, because in the long run it would be cheaper. What I'm concerned with is the bandwidth limit of my house. I know when I'm downloading something off the internet, if I download at high speeds the rest of the computers connected to my router will become slower. Is there any way to avoid this? There are other cable outlets in my house, will connecting a modem and router there avoid this problem?

• Installing 12.04 within 11.04

  - by user288752

  I recently installed 11.04 from an installation disk (overwriting Windows in the process). I know 11.04 is no longer supported but I had no problems subsequently upgrading it to 12.04 (via 11.10) a couple of months ago on another device. This time though, things are different. I can't upgrade through update manager because Ubuntu then tells me I have no internet connection, which is (obviously incorrect). I have tried to circumvent the problem by downloading the 12:04 iso from ubuntu.com directly but now I'm troubled by something else. The download is succesfull but after mounting the iso I can't interact with it. When I try to access the Wubi it gives me the following message: Archive: /home/lars/.cache/.fr-7g75Fe/wubi.exe [/home/lars/.cache/.fr-7g75Fe/wubi.exe] End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive. zipinfo: cannot find zipfile directory in one of /home/lars/.cache/.fr-7g75Fe/wubi.exe or /home/lars/.cache/.fr-7g75Fe/wubi.exe.zip, and cannot find /home/lars/.cache/.fr-7g75Fe/wubi.exe.ZIP, period. What am I doing wrong here?

• Can't type into some text fields in any browser on Windows 7

  - by Zoltán

  I can't type into e.g. facebook's log in form with my computer. I hit my keys, but nothing happens. Special characters like c, c, š, etc. work. Backspace doesn't, delete does. This goes for Internet Explorer, Firefox and Chrome. This also happens with some other sites, sometimes even with gmail (or any google's log in form). I read somewhere that the solution is to reregister some dlls: regsvr32 mshtmled.dll regsvr32 jscript.dll regsvr32 /i mshtml.dll The first two work, the third one says The module "mshtml.dll" was loaded but the entry-point DllRegisterServer.dll was not found. And of course, running just the first two didn't help. Does anyone know how to fix this problem?

• Ping isn't acting accurate?

  - by Earlz

  I've been trying to diagnose some latency issues with my internet connection. I've been lagging out of online video games and such, which of course could be their server's fault. So, I've been running ping some. It doesn't indicate anything unusual, but it does act a bit strange. I can start it with something like ping internethost -i 0.1 so that it will send a ton of packets, and every 10-20 seconds it will appear to just freeze for 2 or 3 seconds. The packets are still being received in the right order though, and there is no packet loss. The weirdest thing is that after the little freeze up, it will usually just report a ping time that is about 10-30ms higher than the average. How does this happen? Is ping still being accurate? I'm using Arch Linux. The host I'm pinging is my website, which shouldn't be doing any kind of ping slowing or filtering.

• Chrome shows "The site's security certificate is not trusted" error

  - by Emerald214

  From this morning I get this error whenever I access Google Docs and some websites. My system datetime is correct and I checked "Automatically from the Internet". My BIOS is OK. I cleared everything (cache, cookie, private data) in Chrome and restarted OS but nothing changes. How to fix it? Firefox works but Chrome has that problem. The site's security certificate is not trusted! You attempted to reach docs.google.com, but the server presented a certificate issued by an entity that is not trusted by your computer's operating system. This may mean that the server has generated its own security credentials, which Google Chrome cannot rely on for identity information, or an attacker may be trying to intercept your communications. You cannot proceed because the website operator has requested heightened security for this domain.

• create a simple game board android

  - by user2819446

  I am a beginner in Android and I want to create a very simple 2D game. I've already programmed a Tic-Tac-Toe game. The drawing of the game board and connecting it with my game and input logic was quite difficult (as it was done separately, canvas drawing, calculating positions, etc). By now I figured out that there must be a simpler way. All I want is a simple grid; something like this: http://www.blelb.com/deutsch/blelbspots/spot29/images/hermannneg.gif. The edges should be visible and black, and each cell editable, containing either an image or nothing, so I can detect if the player is on that cell or not, move it... Think of it as Chess or something similar. Searching the internet during the last days, I am a bit overwhelmed of all the different options. After all, I think Gridview or Gridlayout is what I am searching for, but I'm still stuck. I hope you can help me with some good advice or maybe a link to a nice tutorial. I have checked several already, and none were exactly what I was searching for.

• Value of the HTML5 lang attribute

  - by user359650

  I'm working on a website which will offer localized content following the language+region approach as described on this W3.org page (e.g. fr-CA for Canadian French content, and fr-FR for "French French" content). As we consider content for each language+region to be unique, it is crucial to us that search engines properly identify and serve the content accordingly. By looking up on the Internet (e.g. this question), it appears that most people recommend the use of an ISO639 language code in the HTML lang attribute to describe the content language. Following this recommendation, we would en up using <html lang="fr"> which wouldn't enable the differentiation between the aforementioned language+region combinations. When reviewing the HTML4 specification, it seems that using language+region as a language code would be perfectly OK, as the en-US example is given as one possible value. However I couldn't find any confirmation of this in the HTML5 specification which doesn't seem to provide any example as to the possible allowed values. From there I tried to get a de facto answer by looking at what the web giants are doing. I looked at what Facebook are doing: they offer Candian French and French French versions of their websites with (slightly) different content, whilst the HTML lang value remains the same: fr-CA URL: http://fr-ca.facebook.com HTML lang attribute: <html lang="fr"> translation of the word 'email': courriel fr-FR URL: http://fr-fr.facebook.com/ HTML lang attribute: <html lang="fr"> translation of the word 'email': Adresse électronique Q: What is the recommended/standard way of describing content that was localized using the language+region approach in HTML5 ?
