• HP Envy dv6t-7300: Disabled WiFi through button and can't enable it anymore

  - by Mateus B. Cassiano

  Well, I have a HP Envy dv6t-7300 laptop that came with a Ralink RT5390 WiFi card. Everything was working perfectly, and eventually I press the WiFi button in my keyboard to toggle the card on/off. Until today, all worked right: if the wifi was off (wifi LED amber) and I press the wifi button, after a few seconds the LED turn white and everything works. If I repeat the process, the wifi LED turn amber and the card get disabled, but now, I can't turn it on anymore. running sudo rfkill list all I get: 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no 1: hp-wifi: Wireless LAN Soft blocked: no Hard blocked: yes So, I ran sudo rfkill unblock all but nothing changed. As a side note, if I run sudo ifconfig wlan0 up, the indicator LED gets white (indicating that the card was enabled), but Ubuntu still say that the card is blocked by hardware. Extra information: the card works without issues in windows and in Ubuntu installer (booting from a live CD). I'm using the card out-of-box, using the drivers already included in Ubuntu 12.10. The module rt2800pci is loaded and working fine, not blacklisted, etc, etc. The card and the button toggle worked flawlessly until today, when I toggled it off and can't turn it on anymore... The problem is back, but in a different manner: if I don't press the wifi key a few times during the grub loading, in the login screen the wifi button will be ambar (disabled), pressing it will toggle it white (enabled) or ambar (disabled) again, but ubuntu still says that the network card was disabled by hardware and doesn't connect... In other words, if I don't press the WiFi button a few times when Ubuntu is booting, it will be stuck with the "network card was disabled by hardware" message, even if the light is white (enabled). Any clue? Maybe a error in some startup script or config file?

• How to turn off power metering in HP ILO2?

  - by Baron Throw

  I have an issue with all of my RHEL 5.3 servers, where HP iLo2 power meter checks the power draw of the power supply on the server. However this gets passed to the /var/log/messages in our host, and eventually fills up the logs. Anyone have any idea how to completely disable power meter option in iLo? I checked google and iLo2 documentation provided from HP, but found nothing that tells you how to disable it / turn it off. Maybe some CLI command? Im not sure. The message is: Aug 18 10:11:03 KAMIL-SERVER1 ipstor_hwmond: IPSTOR||1408371063||E||11788||sensors||Power Meter = 108.000 Watts [ low=na high=na]

• How to configure firewall to allow using a specific port

  - by user174416

  I am trying to make tcp ip connection to a server xxx.xxx.xxx.xxx with port xxxx. But I am getting error message "10061 connection refused". I think firewall on the server is stopping my program to access that port. How can I configure the firewall of server to allow my program to use that port. I had asked this question on stackoverflow (http://stackoverflow.com/questions/13448429/socket-error-while-making-tcp-ip-connection-in-delphi) where I was suggested to ask it on super user. Please provide me any solution....

• Upgrade to 0.25, files served to uPNP devices cannot play

  - by David Buttrick

  I have a Sony BDP-S390 bluray & network player. I upgraded my Myth server to 0.25. When I browse to the Myth server, and try to play a recording, I get an error message about the file not being payable in the player. Interestingly, the files that i have recorded, and the videos that I have loaded into my Video volume group are .mpg or .mp4. The player shows the filetype that it thinks the file is in it's list, and it claims that these files are AVI files, however none of them are. They are all .mp4 or .mpg files. Thinking that that was just an optical illusion, I went ahead and tried to play a file, but I get an error about the file not being playable. First of all, is there something that I need to do to make the uPNP server know about different filetypes? Is it reporting AVI because it hasn't been told about MPG or MP4? Second, I'd like to help out some more here and collect some logging about the uPNP server in the myth server. I cant seem to find information on how to turn on logging, and there is no mythbackend settings file int /etc/default. Thanks very much.

• Precise: Evolution laggy due to IMAP -profile or due to some odd Sync -issue?

  - by Izzy

  I'm fighting with Evolution. Basically it's working fine -- but it is very slow to react in certain situations. There is apparently some problem with syncing and IMAP. Helper questios Could be that changing away from Bonobo has to do with slowing-down? There might be some trouble with the new engine and "asynchronous actions". What to do about it? I want to get the previous "working mood" back. How can I speed this thing up? Different scenarios when sending a mail, the composer window hangs there inactive for a couple of seconds, everything grayed out. Though there is a green check mark saying it's sent, I'm not sure a) why it's still blocking everything and b) whether I could simply close it without "breaking"/"losing" anything. In earlier versions, the composer window was closing pretty fast, and one could see the message being stored into the local "outbox" until it was sent, and one could immediately continue with the next task. I prefer that behaviour over the current. switching between modules. Coming from mail and switching to the address book takes a couple of seconds. Same for switching to the calendar. I read about different "possible causes" and tried a few things: I only have 3 local address books, so no networking should be involved here. To make sure, I switched to offline mode and then tried to access the address book. No noticeable difference. I use 3 Google Calendars. Switching to offline mode made a minor difference, but so minor that it also could be "imagination" since one might have expected this in this case according to some reports, disabling the tasks should help. Well, it didn't in my case, as I don't use them regularly (just two local items stored here)

• Prevent machine in a LAN from receiving a remote shutdown

  - by WebDevHobo

  I'm probably just overreacting, but I recently came across a LAN-scanner that showed me the option "remote shutdown", for all found computers on the scanned network. Now, how exactly does this work? If I send such a message, will the shutdown happen no matter what, or is it required to have the password/user-name of the user of that other computer. Mostly I'm wondering: can this be done to me and how do I prevent it? EDIT: what's more, I had the scanner check for shares. The result being this: Double clicking the links opens them in explorer, basically meaning my entire C and F drive(only 2 HD's I have) are completely exposed to anyone in my LAN. Or can I open these because it's my own machine?

• Asterisk failing at startup after upgrading to asterisk18

  - by Supratik

  I was using asterisk16 and asterisk16-skypeforasterisk, which was working fine. I have recently upgraded to asterisk18 and asterisk18-skypeforasterisk, after that I am receiving the following error message. Asterisk ended with exit status 1 Asterisk died with code 1. Asterisk could not start! Use 'tail /var/log/asterisk/full' to find out why. When I checked the log I got the following messages. codec_g729a.c: == Found total of 11 G.729 licenses translate.c: empty buf size, you need to supply one Now, if I remove the /var/lib/asterisk/licenses folder it works fine. Can you please tell me what could be the issue here ? Warm Regards Supratik

• Repair ext4 filesystem on USB drive

  - by phineas

  Yet another filesystem question. I wanted to use a USB drive that I hadn't mounted for a month or so and was surprised by the fact Ubuntu was unable to mount it. I looked it up in the disk utility and it said it discovered a device with 17 MB instead of 2 GB. The hardware looks intact, I hope for the best for repairing the ext4 filesystem. I followed the instructions from HOWTO: Repair a broken Ext4 Superblock in Ubuntu, but I wasn't successful. # fsck.ext4 -v /dev/sdb e2fsck 1.42.5 (29-Jul-2012) ext2fs_open2: Bad magic number in super-block fsck.ext4: Superblock invalid, trying backup blocks... fsck.ext4: Bad magic number in super-block while trying to open /dev/sdb The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 Filesystem blocks are invalid, however when I run the recommended solution to try the alternate superblock, I get the following output: # e2fsck -b 8193 /dev/sdb e2fsck 1.42.5 (29-Jul-2012) e2fsck: Invalid argument while trying to open /dev/sdb plus the same error message as in the last paragraph above. Any ideas how to recover the drive? Thank you very much! Edit: testdisk won't help. I'm still stunned why the tools only discover 17 MB.

• 'Buy the app' landing page implementations: redirect or javascript popup?

  - by benwad

  My site (using Django) has an app that I'm trying to push - I currently have a piece of middleware that redirects the user to a page advertising the app if they're accessing the page on the iPhone, then setting a cookie so that the user isn't bugged by the message every time they visit the site. This works fine, however checking the page with the mobile Googlebot checker shows that the Googlebot gets stuck in the redirect (since it doesn't store cookies) and therefore won't index the proper content. So, I'm trying to think of an alternative implementation that won't hurt the site's Google ranking and won't have any other adverse effects. I've considered a couple of options: Redirect (the current solution), but don't redirect if the user agent matches the Googlebot's UA string. This would be ideal, however I'm not sure if Google like their bot being treated differently from other users, and I'm afraid the site's ranking may be somehow penalised if I go ahead with this. Use a Javascript popup instead of a redirect. This would make sure the Googlebot finds the content it needs, however I envision this approach causing compatibility issues with the myriad mobile devices/browsers out there, and may affect the page load time. How valid are these options? And is there a better option for implementing this feature out there? I've tried researching this topic but surprisingly can't find any reputable-looking blog posts that explore this topic.

• Installing 13.04 on an EFI partition - Share with Windows 8?

  - by mengelkoch

  Information I've found here suggests that for my system, I need to install 13.04 into an EFI-type partition, since it needs to boot as UEFI. I also understand it is advisable to have only ONE EFI partition on the disk; I've read here that it is OK for Ubuntu and Windows to share the same partition (please confirm). When I try to install into the existing EFI drive, I get the message "No root file system is defined. Please correct from partitioning menu." Do I change the EFI boot partition to another type? Doesn't that defeat the purpose? If I change it to Ext4 Journaling File System, I am given the opportunity to define the '/' Mount point. I haven't proceeded beyond this point for fear I am going to destroy Windows 8 by altering this partition. BTW, I created three partitions in Windows before installing, per the helpful response to my previous question. But if I try to install into the partition I created for Ubuntu, I get the "No root file system..." error again.

• OpenVPN useradd error

  - by zfz

  I tried to install an OpenVPN access server in Centos 6 on a linode VPS. The installation is okay for my ubuntu 11.10 distro in another VPS. The installation error occours when adding the user "openvpn" in Centos. The error message is "useradd: canot open /etc/passwd" The detail of My "/etc/passwd" file: "-rw-r--r-- 1 root root 1194 Oct 9 00:33 /etc/passwd" I am not quite familiar with Centos, so how can I add the user "openvpn" in order to setup the VPN service? Thanks.

• How to fix the “Live INT automatically logs out”

  - by ybbest

  Problem: Live INT environment automatically logs out I am trying to setup the Authentication with Windows Live ID and followed this blog post ; I have a problem logging in to live INT web site. Whenever I try to log in (https://login.live-int.com/login.srf  this is the internal Live environment to be used in a dev. environment.), after entering valid email/password I get redirected to the logout page. I tried 2 different accounts (one with existing email address, and other one with newly created @hotmail-int.com address) and 3 different browsers so I’m sure that neither account nor the browser are the cause of this. I also tried to enter wrong password, and in that case I get the message that the password is wrong. Solution: All you need is the unique ID in order to add the user to SharePoint , you can get the ID without logging into the Live INT environment. I think the Live internal environment is not working correctly for some reasons , the reason I need to login to the Live internal environment is that I need to get the unique ID for the test account so that I can add the user to SharePoint. All the blogs I have come across require you to login in order to get the unique ID. However, I figured out another way of getting the unique ID without logging in. Steps are below: Register a new test account in the Live internal environment. Go to the SharePoint site collection that has  Live ID authentication enabled and select the LiveID INT(it will be different as you could name it differently when you set up the authentication provider) from the dropdown. Try login using the Internal Live account, you will get an Access Denied Error as below showing your  unique ID for the test account. Add that account to your SharePoint Group, boom, it works. I hope it will help anyone who needs to do this stuff in the future.

• 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.

  I made a website on which i need to be able to upload video files and it has worked for quite a while. However after a while it just stopped working and now it will give me the following IIS error message when i upload a video. Images do work (possibly due to their smaller size).

If you have any idea what it could be PLEASE tell me, have been trying to fix this for weeks now. Thanks in advance!

• 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.

  I have a bluetooth USB, every time I enter the bluetooth, bluetooth is active only a few seconds, after which it can not be used again In 'devices and printer' there is still a bluetooth but if you want to save the settings it can not, there are error message or bluetooth is revoked.

I've been brain-tweaking drivers for all but still can not.

• Is it possible to upgrade using the Windows Server 2012 evaluation?

  - by Cerebrate

  I've got a Windows Server 2008 Standard installation here that I'm trying to upgrade to Windows Server 2012 Server, using the evaluation version. (The scenario is essentially that I need to test the upgrade, and specifically the upgrade process, before we spend the money on going ahead with the actual upgrade.) When I try to upgrade, it fails with the message: "Windows Server 2008 Standard cannot be upgraded to Windows Server 2012 Standard Evaluation (Server with a GUI). You can choose to install a new... (etc., etc.)" Is this (non-upgradability) a known limitation of the evaluation version? (Unfortunately, I haven't found a clear answer on this point.) And if not, any thoughts on where else I might look for the problem and solutions to it?

• Page won't load on IE9 unless developer tools are started first

  - by RoyHB

  One of my pages (with very extensive javascript) won't load on IE9. It loads ok in Mozilla, Chrome, Safari and Opera. If IE9 Developer tools are running it loads fine. If I load IE9, load the developer tools (F12) then kill the developer tools it still loads fine. If developer tools are running then sometimes (but not always) the first message in the console is: HTML1113: Document mode restart from Quirks to IE9 Standards Doctype is: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> If I change doctype to and remove the xmlns nothing changes. I'm stumped. Any suggestions appreciated.

• Compaq Q2009 monitor display Issues

  - by jasonco

  I have this compaq q2009 monitor 20' inches and I am having display issues. When I turn on the computer the image is displayed fine for a fraction of a second and then the display goes black. If I turn off the monitor and turn it on again the the same thing happens: the image is displayed for a fraction of a second and then goes black. This is odd. I've looked all over the web and I haven't found anything useful (not even in the HP website). So there is no "out of range" or "recommended resolution" message. It just displays and then goes black. I think the resolution is fine because it was working OK until recently and I haven't changed anything in that regard. Any help would be appreciated. Thanks.

• How to identify process that's sending error messages to terminal?

  - by kjo

  The following error message occasionally appears in my terminal: Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file: No such file or directory ...which is pretty annoying. I have searched online for solutions to this error, without success. Is there any way to at least identify the process responsible for sending these error messages to my terminal? EDIT: Let me clarify that, as far as I can tell, these error messages appear "out of the blue". In fact, they appear asynchronously with respect to my interactions with the terminal (more often than not see them for the first time when I return to a terminal window that has been unattended for some time). I'm sure there's a definite, deterministic cause for these messages, but it is not one that I can readily identify. In short, I have not noticed any pattern or regularity to their occurrence. In particular, in my case their occurrence has nothing to do with running mplayer, or any other video playback program. (Please my earlier post about it here.) For one thing, the machine in question is a work machine, and I rarely watch any videos with it. In the very few instances in which I've watched a video on this machine I've used VLC, not mplayer, and these errors never appeared in these rare occasions that I used VLC.

• How do I start control panel with runas in Windows XP?

  - by MrVimes

  Sometimes I need to make a config change on another user's PC. The user doesn't have admin rights so I try to start control panel using the runas command. I can start other stuff with the command but if I try to start control panel nothing happens. It doesn't even give me an error message. Alternatively I start another command prompt as admin (using the runas command again) and from that try to start control panel. Still no joy. Is control panel designed not to be startable from a non-admin profile as an admin user?

• Routing Traffic on Ubuntu to give Raspberry PI Internet Access

  - by Scruffers

  I'm hoping someone can point me in the right direction for setting up my Linux (Ubuntu 12.04) box to route traffic from eth0 to wlan0. I'll try and explain the problem I am trying to solve: I currently have two separate networks: [RaspberryPi/eth0] 192.168.2.2 / 255.255.255.0 ^ | v [Ubuntu/eth0] 192.168.2.1 / 255.255.255.0 And: [Ubuntu/wlan0] 192.168.1.100 / 255.255.255.0 ^ | v [ADSL router] 192.168.1.1 / 255.255.255.0 So currently if I want to access the RaspberryPI I can SSH from the Ubuntu box to the PI. And if I want to use the Internet, I have full access from the Ubuntu box, but nothing from the RaspberryPI - the two networks are partitioned. What I would like to do is configure things so that the RaspberryPI has Internet access via the Ubuntu box and out to the Internet. I tried to create a bridge, but got the message "wlan0: operation not supported" (wireless chipset is Ralink RT3062). I'm sure giving the Raspberry PI Internet access should be easy to do in this configuration, but I am a bit lost - can someone point me in the right direction please?

• Purpose of JBoss tables

  - by Rich

  Hi Can anyone point me in the direction of some documentation (or provide the information here) about the following tables, created by JBoss 5.1.0 when it starts up? I know what they are for at a high level, and know why they are there, but I could do with some lower-level documentation about each table's purpose. The tables are: hilosequences timers jbm_counter jbm_dual jbm_id_cache jbm_msg jbm_msg_ref jbm_postoffice jbm_role jbm_tx jbm_user I know that the first two are associated with uuid-key-generator and the EJB Timer Service respectively, while the rest are associated with JBoss Messaging. What I want to know is something along the lines of "jmg_msg stores each message when it is created...", that kind of thing. I wasn't sure where to ask this question, ServerFault or StackOverflow, but I decided it wasn't programming related so thought I should put it here - I hope that's ok! Thanks Rich

• This operation has been cancelled due to restrictions in effect on this computer

  I have this HUGELY irritating problem on Windows 7 (x64). Whenever I click on ANY link (that exists on a Word document, Excel or Outlook), I get an alert box with the message: This operation has been canceled due to restrictions in effect on this computer I have been scouring my settings and the Internet for a solution, but to no avail. What is the reason for this problem? It even happens when I click anchors in word document. That is, I can't even click on an entry in a Table of Contents to go to the appropriate page - I get this same error then. Is this a Windows 7 thing? Is there any way to turn this off?

• Forcing the from address when postfix relays over smtp

  - by John Whitlock

  I'm trying to get email reports from our AWS EC2 instances. We're using Exchange Online (part of Microsoft Online Services). I've setup a user account specifically for SMTP relaying, and I've setup Postfix to meet all the requirements to relay messages through this server. However, Exchange Online's SMTP server will reject messages unless the From address exactly matches the authentication address (the error message is 550 5.7.1 Client does not have permissions to send as this sender). With careful configuration, I can setup my services to send as this user. But I'm not a huge fan of being careful - I'd rather have postfix force the issue. Is there a way to do this?
