  • Troubleshooting Mid 2007 iMac RAM upgrade

    - by MDT
    I am trying to install new RAM in my friends iMac, something I have done several times before. We unplugged the computer before performing the upgrade, used anti static wrist bands, and yes the memory is compatible and inserted correctly. The stock RAM was Hynix 1gb pc2-5300s-555-12 and the memory we are replacing it with is 2x2gb Centon CMP800SO2048.01. Now I know this model number suggests that the ram is 800MHz and the iMac is only 667MHz but it clearly states on the box that this RAM is PC2-5300 667MHz compatible. The problem is, that when I install the new RAM I get little response from the computer. I hear the hard drive and disk drive start to initialize, but then they just stop and the screen remains black. I have tried every variation of the new RAM and the old RAM in both slots and even tried the same RAM from my old iMac and I just can't get it to boot. Has anyone ever had a problem like this? Thank you in advance for any and all input on thus issue!

  • Mysql Fail to start

    - by John Naegle
    I'm running a Ubuntu 12.04 LTS Virtual Machine. Last week, the VM stopped unexpectedly now mysql will not start on the VM. These two events may be related, they may not be. When I try to connect: $ mysql ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) Then: $ sudo service mysql start start: Job failed to start And $ dmesg [ 1838.218400] type=1400 audit(1374633238.253:50): apparmor="STATUS" operation="profile_replace" name="/usr/sbin/mysqld" pid=18473 comm="apparmor_parser" [ 1838.358656] init: mysql main process (18477) terminated with status 1 [ 1838.358695] init: mysql main process ended, respawning [ 1839.269303] init: mysql post-start process (18478) terminated with status 1 And $ service mysql status mysql stop/waiting I think this means mysql is crashing when it starts: $ sudo mysqld start 130723 21:51:24 InnoDB: Assertion failure in thread 3064211200 in file fut0lst.ic line 83 InnoDB: Failing assertion: addr.page == FIL_NULL || addr.boffset >= FIL_PAGE_DATA InnoDB: We intentionally generate a memory trap.

  • Ubuntu 9.10 desktop installation via USB (boot)

    - by user277980
    I have made a live boot USB using the UnetBootIn tool for Ubuntu 9.10. I have Windows XP SP2 installed as the primary OS, and I want to make a partition for Ubuntu. But when I try to boot it via USB, it just goes to boot menu of Ubuntu, then I enter the default type for installation. After that nothing happens, just the Ubuntu logo shows up and just that nothing happens after that. I can try the simpler task also i.e. install via CD but I want to know what's not working with this USB boot method. Thanks in advance.

  • Are HDMI to VGA Adapters Really Device-Specific?

    - by allquixotic
    There are a lot of devices on the market right now (especially mobile devices) with a Micro-HDMI or Mini-HDMI port and no VGA or D-Sub output. Most manufacturers of said devices sell a cable that looks something like this: I have yet to find a cable like this that claims to work on a wide array of devices. In general, these cables claim to work with one specific device only. The way these cables work, I think, is that analog VGA signals are sent from the HDMI port on the device. This should work for devices that have special hardware on the motherboard/GPU capable of driving this. Is it the case that these cables have to be custom designed for each device? Or, is it rather that any device which possesses this special "signaling of analog VGA over the HDMI port" can be made to work with a cable that is physically compatible (i.e. the HDMI end plugs into the device and the VGA end accepts a VGA monitor cable)? Note that I am not looking for a product recommendation, just a conceptual clarification on what exactly these devices are doing. Also, a few remarks: The cables like the one depicted here are not digital to analog converters. I know about these: they are expensive, and they are the ONLY solution if your device only outputs a digital signal and is incapable of driving analog VGA over the HDMI port. The cables like the one depicted here are not straight crossover cables from VGA to HDMI, either. The crossover cables are designed to send a digital HDMI signal over the VGA port's wires; that is, the wire protocol is HDMI (digital) but the physical pinout is the same as VGA, even though nothing analog is happening. Once again, this is not the behavior that, I believe, the devices which I'm talking about in this question are doing. The cabling and devices that this question is about transmit the analog VGA data over the HDMI port (the HDMI port is in the device outputting the data, and the VGA side is the monitor/projector).

  • How can I get the root account to generate an acceptable ssh key?

    - by Jamie
    On an ubuntu machine I did the following: ~$ sudo su - [sudo] password for jamie: root@mydomain:~# ssh-keygen -t rsa Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /root/.ssh/id_rsa. Your public key has been saved in /root/.ssh/id_rsa.pub. The key fingerprint is: 12:34:56:78:9a:bc:de:f0:12:34:56:78:9a:bc:de:f0 [email protected] The key's randomart image is: +--[ RSA 2048]----+ | | | | | | | | | | | | | | | | | | +-----------------+ root@mydomain:~# cat /root/.ssh/id_rsa.pub | ssh -p 443 [email protected] 'cat > authorized_keys' [email protected]'s password: root@mydomain:~# ssh -p 443 [email protected] [email protected]'s password: It's asking me for a password. However, using a regular account, the following works: $ cd ; ssh-keygen -t rsa ; cat ~/.ssh/id_rsa.pub | ssh [email protected] 'cat >> ~/.ssh/authorized_keys' $ ssh [email protected] Last login: Thu Oct 24 14:48:41 2013 from 173.45.232.105 [[email protected] ~]$ Which leads me to believe it's not an issue of authorized_keys versus authorized_keys2 or permissions. Why does the 'root' account accessing the remote 'jamie' account not work? The remote machine is CentOS if that's relevant.

  • Complete refresh of the OS - windows 7.

    - by Vael Victus
    So, the girlfriend's got a virus, and it's pretty nasty. I don't have the time to mess around with it, and she's not so bad with computers, but this is out of her league. (considering her idea of fixing the problem was to download a virus scan that was malware itself) I think I remember hearing that it's possible to put in some restore/recovery disk that comes with the computer to bring Windows back to the way it was originally right from the factory. The problem is, I bought that computer off the shelf - literally - and I don't think I received a disk, or if I had, it's probably gone now. Do you guys have any idea what I could do? I'm all for reformatting, it's just a toy PC for her. I just don't have a disk to re-install windows 7 with.

  • Where to learn how to replicate an Excel template?

    - by Rosarch
    This Excel template is really cool. There are a lot of things in it I don't know how to do, such as: Having header rows that "stick" to the top even when you scroll down Slider on the first page changes where the chart pulls its data from Functions seem to be referring to named ranges in tables, like =SUM([nov]). Where do those names come from? Clicking "back to overview" on the "Budget" page returns you to the "Dashboard" page The number under "starting balance" of the top right corner of "Budget" changes when you change cell C5 On "Budget", each cell in the first column of each table has a drop-down menu for text, which seems to come from the "Setup" page The background isn't just plain white, but when I try to format paint it onto a new sheet, nothing happens If you know how any of these effects are achieved, I'm definitely curious. But I guess the main point of my question is where I can go to answer these questions for myself. Are templates explained anywhere?

  • How do I stop apps trying to use a dial-up connection?

    - by ProfKaos
    Every now and again, I might have to use a dial-up internet connection via another tethered phone, i.e. Bluetooth connection to the GPRS modem. Now I am back on 'ops normal', i.e. using a shared internet connection on my own phone, or on my 3G stick, but some apps, especially IE9, keep popping up a 'dialup connection' dialogue, which I cannot dismiss enough times ever, to make to stay away. How can I tell these idiot applications that I no longer need a dial-up connection?

  • Why would ssh fail to expand %h variable in .ssh/config?

    - by Zoran
    Why would ssh fail to expand %h from .ssh/config? This used to work and still works except on a RHEL box. Looking for what the origin of this could be. Is there a setting somewhere that tells ssh to not expand %h? I have something like this in my .ssh/config: Host *.foo HostName %h.mydomain.com On the RHEL box where this doesn't work, I get this: $ ssh -vvvv bar.foo OpenSSH_5.3p1, OpenSSL 1.0.0-fips 29 Mar 2010 debug1: Reading configuration data /home/zsimic/.ssh/config debug1: Applying options for *.foo debug1: Applying options for *.foo debug1: Applying options for * debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug2: ssh_connect: needpriv 0 ssh: Could not resolve hostname %h.mydomain.com: Name or service not known

  • MAC OSX Mavericks, using bash to see "Get Info" attributes

    - by Rell3oT
    I want to use my bash shell to see the attributes that are shown when you right click on an Application and click Get Info. The specific attributes that I want to know whether or not they are checked is Open in Low Resolution, Prevent App Nap, and Locked. I looked in the Info.plist file but only generic information about the file was contained here, not which attributes were checked. Is this information contained in the Applications binary? Where is it?

  • Wicd not playing well with networks that utilize network access control

    - by Sion
    Starting a couple months ago (might be able to find exact date if necessary) my installation of Wicd stopped being able to see wireless networks that use NAC (Network Access Control) such as Aruba networks. But if I shut down Wicd and start NetworkManager I can connect to said networks and log in to them depending on what the NAC requires. This is the current wicd package installed: net-misc/wicd-1.7.1_pre20111210-r1 This is how I manipulate the network manager running: su -c'/etc/init.d/wicd stop; /etc/init.d/NetworkManager start' What would cause this specific of a problem to occur?

  • Bonjour/DNS Service Discovery queries

    - by senloe
    I'm trying to implement dns service discovery in my application (no, I'm not asking for a programmatic answer). What I believe is one of my big pain points is generating the query. I know I need to send out a multicast broadcast on port 5353 and want to look for devices of type _ipp._tcp and _print._tcp, but I don't know what the question section needs to look like. For example, in SSDP I sent out a query that looks like the following: "M-SEARCH * HTTP/1.1\r\n" "HOST: 239.255.255.250:1900\r\n" + "MAN: \"ssdp:discover\"\r\n" "ST: urn:schemas-upnp-org:device:Printer:1\r\n" "MX: 5000\r\n\r\n" From what I know about a DNS query I need to send something like: "_ipp.tcp,all,all" but I know there needs to be more. Any pointers to documentation, etc would be greatly appreciated! update rfc1035 appears to contain promising information re the message structure.

  • Fan twitches and LEDs blink when computer is plugged in

    - by Zifre
    I just finished assembling a desktop for the first time. The specs are: Gigabyte GA-H55M-S2H motherboard Core i3 530 CPU 4 GB DDR3 RAM 1 TB SATA hard drive 500 Watt PSU As soon as I plug in the computer, the "phase LED" starts blinking orange and the system fan LED blinks while the fan "twitches". This continues until about three seconds after I unplug the computer. This worries me a lot because I haven't even turned the computer on and it continues even after there is no power. I did make sure the PSU is on the proper power setting. What is causing this and how can I fix it? Is the motherboard dead?

  • Sync files between Mac, PC and Linux automatically

    - by Siriss
    Hello everyone- I have a MacBook Pro, a Windows 7 desktop, and a Fedora 13 netbook. I have been searching far and wide for an automatic solution to sync files (pictures, music, docs, etc...) between the three when they are all on the same LAN. To better explain, when I get home and turn my MacBook on, I want it to sync automatically any file changes to Windows 7 and the netbook. Likewise if I make changes on my Windows 7 box, I want them to be reflected on my Mac. I can use rsync, but it is not automatic as far as I can tell, and I would use Dropbox but I have a lot more that 2 gigs and do not want to pay. I also do not need internet syncing. I just want local LAN. Does anyone have any ideas? Thank you very much in advance.

  • GTX 280 purple snow on bootup, card works without drivers

    - by Brokar
    i have owned a ASUS GTX280 for 3 years now. The card has been great all along but i started having problems 10 days ago. I was playing Diablo 3 for 1 week on max settings no problems, then suddenly my display kept getting some weird purple/colours as soon as i booted and logged into windows. Went into safe mode, updated drivers and it kept crashing. Formatted PC, fresh windows install with new WHQL drivers again same problem. Uninstalled nvidia drivers and pc has been running great for 4 days now, ofcourse i cannot run games but everything works on 1680x1050 resolution and i can browse internet,watch movies and use my PC for everything but gaming. As soon as i install nvidia drivers PC won't boot. I only wanna game a few hours a week (very busy program with school this month so it might be a blessing that i cannot game) and i would love it if i could keep the card. I am looking to upgrde later on when i will have time for gaming but i wonder if i could still use the card somehow with different/new drivers (tried older drivers that came with the card on a CD aswell) tldr: PC works fine with no nvidia drivers (apart from gaming ofc). Once i install WHQL drivers or older ones, cannot even log into windows. Fix?
