  • Eclipse Indigo freezes on 'Open Type' search

    - by NickGreen
    When I'm trying to search for a Java class with Ctrl-shift-T (Open Type popup), Eclipse freezes when I'm typing 1 character. It usually takes about 8 seconds to 'unfreeze', but sometimes it won't come back at all.. When it freezes, I see that the eclipse process takes about 1Gig of mem and the CPU is about 100%! I've tried creating a new workspace, adjusting the eclipse.ini (perm size, different memory values), starting with -clean and at last reinstall the whole IDE. Nothing helps.. My eclipse.ini: -startup plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar --launcher.library plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.100.v20110505 -product org.eclipse.epp.package.jee.product --launcher.defaultAction openFile -showsplash org.eclipse.platform --launcher.XXMaxPermSize 768m --launcher.defaultAction openFile -vmargs -server -Dosgi.requiredJavaVersion=1.5 -Xmn128m -Xms1024m -Xmx1024m -Xss2m -XX:PermSize=128m -XX:MaxPermSize=128m -XX:+UseParallelGC -Djava.library.path=/usr/lib/jni I'm using the following plugins: JRebel and m2e. I'm desperate for a solution because this problems causes me a great deal of time loss. System: Ubuntu 12.04 LTS 64 bit, 4GB mem, Intel core i7 860 @ 2.8 Ghz. Hope somebody knows a solution. Thank you for your time.

  • All computers on network get stuck waiting for some sites indefinetely

    - by zacaj
    This happens across three computers, running windows 7 and Ubuntu, firefox, opera, and chrome (all latest versions). I am connected to the internet through a Verizon wireless usb modem. When I try to open some web pages they will never finish loading (and usually never even show anything). The status bar at the bottom of the browser will display "Waiting for X" The servers it gets stuck on include: platform.twitter.com s7.addthis.com connect.facebook.net ajax.googleapis.com 2mdn.net Ive been getting away with just blocking them in AdBlock up until now, however the last two have been causing problems. There are some sites which require googleapis.com to load correctly, and some that wont ever load unless its blocked. eBay requires access to 2mdn.net to load pictures. On top of this its getting really annoying having to update AdBlock across all these computers whenever a new site pops up. I'm hoping there's some easier way to fix this? The different sites causing the freeze indicate to me that it's either a problem on my end (somehow?) or some server side software that got updated with a new bug?

  • Gigabit network limited to 25MB/s by CPU. How to make it faster?

    - by netvope
    I have a Acer Aspire R1600-U910H with a nForce gigabit network adapter. The maximum TCP throughput of it is about 25MB/s, and apparently it is limited by the single core Intel Atom 230; when the maximum throughput is reached, the CPU usage is about 50%-60%, which corresponds to full utilization considering this is a Hyper-threading enabled CPU. The same problem occurs on both Windows XP and on Ubuntu 8.04. On Windows, I have installed the latest nForce chipset driver, disabled power saving features, and enabled checksum offload. On Linux, the default driver has checksum offload enabled. There is no Linux driver available on Nvidia's website. ethtool -k eth0 shows that checksum offload is enabled: Offload parameters for eth0: rx-checksumming: on tx-checksumming: on scatter-gather: on tcp segmentation offload: on udp fragmentation offload: off generic segmentation offload: off The following is the output of powertop when the network is idle: Wakeups-from-idle per second : 61.9 interval: 10.0s no ACPI power usage estimate available Top causes for wakeups: 90.9% (101.3) <interrupt> : eth0 4.5% ( 5.0) iftop : schedule_timeout (process_timeout) 1.8% ( 2.0) <kernel core> : clocksource_register (clocksource_watchdog) 0.9% ( 1.0) dhcdbd : schedule_timeout (process_timeout) 0.5% ( 0.6) <kernel core> : neigh_table_init_no_netlink (neigh_periodic_timer) And when the maximum throughput of about 25MB/s is reached: Wakeups-from-idle per second : 11175.5 interval: 10.0s no ACPI power usage estimate available Top causes for wakeups: 99.9% (22097.4) <interrupt> : eth0 0.0% ( 5.0) iftop : schedule_timeout (process_timeout) 0.0% ( 2.0) <kernel core> : clocksource_register (clocksource_watchdog) 0.0% ( 1.0) dhcdbd : schedule_timeout (process_timeout) 0.0% ( 0.6) <kernel core> : neigh_table_init_no_netlink (neigh_periodic_timer) Notice the 20000 interrupts per second. Could this be the cause for the high CPU usage and low throughput? If so, how can I improve the situation? The other computers in the network can usually transfer at 50+MB/s without problems. And a minor question: How can I find out what is the driver in use for eth0?

  • System With Two Network Adapters [closed]

    - by Synetech inc.
    Hi, My system has a NIC (Marvell Yukon) built-into the motherboard, but I also have a D-Link (RealTek) card. I figure that using the D-Link and disabling the Marvell makes the most sense, though I'm wondering if maybe the built-in one has better throughput (not that my Internet connection is so fast). Also, I'm wondering about the merits of using both at the same time. My router has four ports and I have experimented with enabling and plugging both NICs into the router. I was able to connect to the Internet, but the pattern of usage seemed irregular (which adapter was chosen for the transfer and any given point). I also considered bridging the two, but am having difficulty in finding out what exactly creating network bridge does in the context of the Windows Network Connections window. I am familiar with the concept of connecting networks, so it seems to me that birding two connections on the same segment is pointless at best (and can cause problems like loops?) Does anyone have any tips on what to do if a system has more than one NIC and any clarification on the bridge option? Thanks a lot.

  • CentOS server. What does it mean when the total used RAM does not equal the sum of RES?

    - by Michael Green
    I'm having a problem with a virtual hosted server running CentOS. In the past month a process (java based) that had been running fine started having problems getting memory when the JVM was started. One strange thing I've noticed is that when I start the process, the PID says it is using 470mb of RAM while the 'used' memory immediately drops by over a 1GB. If I run 'top', the total RES used across all processes falls short of the 'used' listed at the top by almost 700mb. The support person says this means I have a memory leak with my process. I don't know what to believe because I would expect a memory leak to simply waste the memory the process is allocated not to consume additional memory that doesn't show up using 'top'. I'm a developer and not a server guy so I'm appealing to the experts. To me, if the total RES memory doesn't add up to the total 'used' it indicates that something is wrong with my virtual server set-up. Would you also suspect a memory leaking java process in this case? If I use free before: total used free shared buffers cached Mem: 2097152 149264 1947888 0 0 0 -/+ buffers/cache: 149264 1947888 Swap: 0 0 0 free after: total used free shared buffers cached Mem: 2097152 1094116 1003036 0 0 0 -/+ buffers/cache: 1094116 1003036 Swap: 0 0 0 So it looks as though the process is using (or causing to be used) nearly 1GB of RAM. Since the process (based on top is only using 452mb, does that mean that the kernal is all of a sudden using an additional 500mb?

  • On Ubuntu get: "-bash: ./flume No such file or directory" BUT flume is there and executable. Same binary OK on RHEL

    - by lcbrevard
    This is already posted in serverfault - and may be more apprpriate there. Reworked a bit from the orginal posting. We have a product built on CentOS 4 32-bit Linux that runs unmodified on 32- and 64-bit CentOS/RHEL 4 and 5 and SLES 10. It also runs unmodified on SLES 9 64-bit. [SLES 9 32-bit requires a different libstdc++.] The name of the main binary executable is 'flume' Yesterday we tried to put this on 64-bit Ubuntu 10 and, even though the file is there and the right size, we get: -bash: ./flume: No such file or directory 'file flume' shows it to be a 32-bit ELF (can't remember the exact output and the system is on an isolated network) If put into /usr/local/bin, then 'which flume' returns: /usr/local/bin/flume The file is marked as executable (did 'chmod +x flume') and lsattr shows no problems with attribute bits. I was not able to try 'ldd flume' yet. I have also not tried 'strace flume'. Currently I am with an air conditioning failure. [It's been that kind of week!] I now suspect that some library is not there. This is a profoundly unhelpful message and one I have never seen before. Is this peculiar to Ubuntu or perhaps just to this installation. We gave up and moved to a RHEL 4 system and everything is fine. But I sure would like to know what causes this.

  • Exchange on SBS2003 not receiving mail, but sending via telnet works

    - by YDdraigLas
    Last week we had a problem on our SBS2003 server where our external connection dropped out and I was only able to restore it by running netsh winsock reset catalog and netsh int ip reset. Thinking all was well, I went home for the weekend and came in today to find that we haven't received any external emails since before the original problems occurred. There are plenty of examples of this on the internet, usually to do with a firewall issue, but the odd thing here is that when I connect using telnet I can send an email and it goes straight through and into my inbox. When I send an email from Gmail or Hotmail nothing comes through at all. Internal emails are also unaffected, as are outgoing emails. There have also been a couple of emails that have come through for other users, both out-of-office replies, if that's relevant. I've run the CEICW several times, checked all the NIC settings, but no joy. Before I give up trying to fix this and reinstall the whole server, has anyone come across this problem before? I have only found fleeting references to this in previous searches and no real answers. Any advice gratefully received.

  • Outlook 2010 Crashing Unpredictably

    - by cbkadel
    Very often when I open up Outlook 2010 and start doing actions in it, it will hang and become non responsive. I have tried letting it finish, but it never does come back (up to 20 minutes of letting it try). I generally have to restart Outlook and try again. Usually after about an hour of doing this, Outlook somehow snaps out of it and works for the rest of the day. It's generally in the morning (though I doubt that's the key variable). Generally, the emails that cause problems are HTML/formatted, but not always. What I've done so far to troubleshoot: Install Latest Outlook Hotfix (I think Dec 14, 2010) Start Outlook in Safe Mode Neither of those steps seem to make a difference. Usually - after about 10-15 restarts of Outlook on any given day, then it starts working thereafter. My next step is to uninstall/reinstall Office 2010, but I'm hoping someone has seen this and knows what to do about it - though not sure. My configuration is like this: Microsoft Online Services (using Microsoft's Sign In App) - Connecting to Exchange I have two other Exchange accounts in this profile (new feature in 2010) connected through Outlook Anywhere. Life Meeting Conferencing Add In I've disabled the People tab/add in. I've disabled the "Send to Bluetooth" add-in. Not sure what else to do?

  • Separated virtual networks with same subnet range with 2 interface

    - by Coolpet
    I'm having some problems with routing with the following: I have a server with 2 interfaces. It has 1-1 alias contains the same subnet. the 2 interface is connected to 2 switch, which are separated from each other. Infrastructure: Eth0 192.168.16.2/20 Eth0:eth0 192.168.1.222/20 Eth1 192.168.32.3/20 Eth1:eth1 192.168.1.223/20 I have a PC which has the IP address: 192.168.1.3/24 The problem is the next: If PC is on subnet 1, I can ping it. If PC is on subnet 2, I can't ping it. traceroute shows the route is across 192.168.1.222 ping -I 192.168.1.223 192.168.1.3 is not working on subnet 2. arp entries show the MAC address belonging to the correct interface (eth1 on subnet 2) How can I force the server to look on both interface same ranged subnet for specific IP? It searches only in the first subnet. The routing table has these 2 entries: 192.168.0.0/20 dev eth0 proto kernel scope link src 192.168.1.222 192.168.0.0/20 dev eth1 proto kernel scope link src 192.168.1.223

  • Repairing Windows 7 boot after Ubuntu 10.10 install

    - by Ted
    I've read various threads on this after googling, including one on this site. I had Windows 7 installed on an SSD. I wanted to try Ubuntu so I created a partition for it on the SSD and booted with the live CD to install Ubuntu. Went through the install and somehow Ubuntu carved out another partition on the SSD rather than using the one I had already created. Windows 7 would then not boot but Ubuntu would. I booted with my 7 cd and ran the automatic startup repair, it didn't find any problems. I then ran the bootsect command on the drive with 7. It said it repaired the bootmgr but Windows still would not boot and now Ubuntu won't either. I read somewhere else that it may be due to the partition that 7 was on being changed during the install. I don't care about the Ubuntu installation but I don't want to lose the 7 install, can I delete the ubuntu partition through booting with the 7 cd? Will that do any good? Thank you all! I'm stumped even though I've done startup repairs before, just not after Ubuntu install.

  • D-Link wireless router losing outbound data

    - by gsteinert
    I have a Linux box running the Apache web server behind a D-Link wireless router (nothing fancy, just standard kit that comes with Virgin Media broadband). My issue is that when requesting web pages (from within the network or via the web), the back end of the page seems to be being dropped. For example, I tried to display a text-only file, and all I could get was the first 40-70% of the file (it changed slightly with each refresh). The apache access logs show that only part of the data was being sent (~6000 bytes instead of the 12000+ bytes of the file). Removing my router from the equation fixes the issue and I can download any files no matter the size with no problems. My theory is that the uploaded packets are either being dropped or held up by the config of the router. Is there anything I can do to alleviate the problem? (Perhaps a way of reconfiguring the router to upload packets harder/better/faster/stronger or an option in apache that provides a workaround) As a last resort I will get a second NIC for my Linux box and turn it into a router, but that would mean the box will be on 24/7... not the most ideal of circumstances.

  • What are the best linux permissions to use for my website?

    - by Nic
    This is a Canonical Question about File Permissions on a Linux web server. I have a Linux web server running Apache2 that hosts several websites. Each website has its own folder in /var/www/. /var/www/contoso.com/ /var/www/contoso.net/ /var/www/fabrikam.com/ The base directory /var/www/ is owned by root:root. Apache is running as www-data:www-data. The Fabrikam website is maintained by two developers, Alice and Bob. Both Contoso websites are maintained by one developer, Eve. All websites allow users to upload images. If a website is compromised, the impact should be as limited as possible. I want to know the best way to set up permissions so that Apache can serve the content, the website is secure from attacks, and the developers can still make changes. One of the websites is structured like this: /var/www/fabrikam.com /cache /modules /styles /uploads /index.php How should the permissions be set on these directories and files? I read somewhere that you should never use 777 permissions on a website, but I don't understand what problems that could cause. During busy periods, the website automatically caches some pages and stores the results in the cache folder. All of the content submitted by website visitors is saved to the uploads folder.

  • Group Policy - Published software not upgrading

    - by VokinLoksar
    I'm testing this with mercurial MSIs, but it's the same for other packages. I've created a new group policy and added an old version of mercurial to User software installation as a Published package. On a Windows 7 client I install the package through Programs and Features. The installation works fine. Now, I would like to publish an updated version of mercurial. I create a new Published package. Under 'Upgrades' I configure it to replace (upgrade also doesn't work) the old version and mark this upgrade as 'Required'. The old package is not removed. The Windows 7 client is then restarted. When I log back in, I see a status message saying something like 'Removing managed software Mercurial ...'. There is no message about installation of the upgrade. If I look in Programs and Features, I can see the new version of mercurial listed. However, the actual mercurial directory under Program Files is missing. It's as though the installation recorded information about the MSI, but didn't actually install anything after removing the old version. As I mentioned, this isn't specific to mercurial. I've tried using other apps and have yet to find one that can be upgraded via a Published package. Using Assigned packages in Computer Configuration works without problems, but I would like this software to be optional rather than required. Ideas?

  • How to copy VirtualBox VDI contents to a partition and dual boot the OS from it?

    - by Calmarius
    I'm a Linux user but I keep a compressed Windows XP ISO with me on a pen drive for the case I absolutely need Windows to do something. This works in VirtualBox most of the time. But now I want to play some games, so I would like to run the Windows image natively. My computer don't have CD drive so cannot just burn the ISO and make an install normally. What I trying to do is moving the installed Windows image to a physical NTFS partition on my HDD and set up GRUB to let me dual boot it. I found many tutorials that deal with making VDI to physical drive. But they assume I want to overwrite my entire drive. Moving the raw disk image with dd to the partition resulted in a corrupt partition. I also tried the VMDK trick to use that empty partition and install the Windows on it. Although the text mode phase of the installation finishes without problems, the VM won't work, either crashes and keeps rebooting or just immediately or freezes (depending on how I created the VMDK, with -rawdisk /dev/sda3 or -rawdisk /dev/sda -partition 3).

  • IIS 7: One Page Works, All Others Fail With "Error code: ssl_error_rx_record_too_long"

    - by Michael
    On my local machine, I have a second site bound to Port 81. Within that site is a certain page which I can browse from other machines with no problems, but all other pages fail with "Error code: ssl_error_rx_record_too_long". Each of the failing pages (as well as the lone working page), works with localhost. So, from any machine, local or remote: http://cmwmach01.mydomain.biz:81/RD/SS/SS.aspx (works) http://cmwmach01:81/RD/SS/SS.aspx (works) http://cmwmach01.mydomain.biz:81/RD/POV/SC.aspx (fails - gets changed to https) http://cmwmach01:81/RD/POV/SC.aspx (fails - gets changed to https) Everything works with localhost (locally, of course). I've tagged this question with SSL because, at one point, it would warn about an SSL cert issue (maybe this was self-signed at one point?), but now it doesn't. While there may be an issue around that, I don't see how this could cause the issue I am seeing (but, as I mention below, am I way out of my depth here). I am way out of depth here in trying to figure out why that one page works (or the others don't), so that I can make them all work. Any ideas?

  • Need help ttoubleshooting PC

    - by brux
    I have had problems since my dog pee'd on my computer. Problem: loads windows fine, at random intervals from 5 minutes to 30 minutes it restarts itself. There is nothing in the event log such as errors, no BSOD, just cold restart. after rstarting - sometimes- it POST's and restarts itself at the end of POST. It will do this many times and then finally load windows. The cycle then begins again, it will restart eventually. What i have done: I thought it was HDD at first, since this is the only part of the coputer which actually got wet with any fluid ( the case is off the PC and the dog pee'd down the front where the HDD is located). Seatool, the seagate HDD tool, found errors when I ran it inside windows, so I ran it in DOS mode from bootable USB and ran it. It found the same number of errors and fixed them all. I ran the scan again and it says "Good". I loaded windows and ran the scan and it also said "Good there. So the HDD apears to be fine but the problem persists, random restarts. What else could this be? I have taken the computer apart and cleaned everything and also taken the PSU apart and cleaned it thoughrouly. The problem still persists, what should my next steps be? Thanks in advance.

  • NTbackup doesn't complete on system state

    - by Joe Majsterski
    I have a Windows 2003 server that is running a semi-custom backup task. The scheduled task calls NTbackup with a few switches depending on whether it is a full or incremental backup. Most of the time, the NTbackup completes fine, and the wrapper then appends the NTbackup log into its own log before adding a few final comments and completing. The problem I am having is that sometimes, NTbackup seems to just... blank out. It always completes backup of the C: and E: drives, but then it will start the system state and not add any more messages into the event log saying it completed that. And the NTbackup log is left empty, since it doesn't write anything to the log until all the backup tasks are complete. This is causing the wrapper to append no text into its own log. That causes problems for us because we read the information out of that log to determine whether backups are failing. The wrapper task also reports that it is completing normally in the event log. Anyone ever seen a case where system state doesn't complete consistently? To be clear, the server is not logging any error messages anywhere. It's just not seeming to complete or log anything.

  • Apache Virtualhost entry with Windows hostname

    - by gshauger
    I have a Windows Domain Controller and we use it for DNS for our internal network. I have an Ubuntu box with an IP address of 172.16.34.149. Within the Windows DNS I created the forward and reverse lookup entries for the name Endymion. Naturally when ever I FTP/SSH/HTTP/etc to the hostname Endymion it resolves correctly to my Ubuntu box. I wanted to do some web development on this box for an existing site. There were problems when I placed the website in a subfolder of /var/www/. Let's just say it was in folder /var/www/projectx/. The issue involved the incorrect resolution of non-relative urls. So I figure I could create a new DNS entry for the hostname projectx. Sure enough when I FTP/SSH/HTTP/etc to the hostname projectx it takes me to the same ubuntu box as the hostname Endymion...this is what I would expect. I now have two hostnames for the same box. I then create a Virtualhost entry in httpd.conf that looks like the following: <VirtualHost *:80> DocumentRoot /var/www/projectx ServerName projectx ServerAlias projectx </VirtualHost> Sure enough when I go to a browser and type in http://projectx/ it takes me to the correct subfolder. Everything works!!! Not so fast. I then go to http://endymion/ and instead of taking me to /var/www/ it takes me to /var/www/projectx/ Clearly I'm missing something. Help please! ;)

  • Is my "Generic" USB Flash Drive broken?

    - by Jesse J.
    So here is the situation. I find myself technological knowledgeable about many things ( I love to code, whether it's websites, C#, C++ or so on). However: My 2 toddlers (my wife actually) bought me a "Generic" 128 GB USB Storage Device (Usb Flash Drive) for Father's Day. I thought awesome at first..... WRONG! Nothing but problems with it. 3-4mb/s MAX transfer speed. I can bear with it. BUT! When I went to reformat my computer I transferred my save files from my games over to the stick and then the USB Stick managed to become corrupted. Not just a simple format would work either. It's screwed. I tried to use (Manually changed usb drive letter troubleshooting it to X) "chmod X: /X /F /R" with administrator rights, I did this after a long session to make it work with no errors (had to delete the log) and I finally recovered the files, however when I go to use it (transfer to or from) it transfers a couple kb to the stick or from it and then freezes, It says (Windows 7): Name: From: Folder (X:\File\Location) To: Folder C:\Users\Username\Desktop) Items Remaining: 0 (0 bytes) Speed: 0 bytes/second It does this forever... and ever... and ever... It transfered 3 files atleast, and then stopped. This is a new USB Stick bought from a "High" reputation company on eBay. Is the USB Stick screwed?

  • Permissions error when creating desktop shortcut

    - by Ryan M.
    Hey guys, I have a user that's got a weird permissions problem on Windows 7. He's trying to create a shortcut for Outlook on his desktop(he doesn't want it in his start menu or his taskbar...). If we right click the outlook.exe and do Send to Desktop, it works just fine. If we do a search for "outlook" in the search bar, and then try and drag and drop the outlook icon to the desktop, we get the error message "You need Permission to perform this action. You require permission from SYSTEM to make changes to this file: Microsoft Office Outlook 2007". Dragging and dropping other exe's onto the desktop work just fine. They create shortcuts without any problems. But if I try to do ANY of the Office programs (Word, Excel, Outlook, etc..) I get this permission error. Any ideas? He's using an A.D. account and he's in the local administrators group. He's an executive so he's not accepting "this isn't a real problem because I found another way to make a shortcut" as an answer. Any help is appreciated.

  • i7-980X at 70% speed

    - by Buxley
    Hi we bought a nice computer to use to solve optimization problems. Intel i7-980X@3,33 GHz with 12 GB of Team Group 1600 MHz DDR3 RAM. When we use Gurobi the computer uses all 12 cores at maximum in the beginning of the solve. However after a while (about 8 hrs) it all cores jump between 65 and 85% When I solve the same models on an i7 930 all cores are at a near 100% level even after longer solution times. We first thought that the Hard disk was the bottleneck since Gurobi writes out nodefiles after the memorylimit is used. However since the new computer have 12 GB of RAM we put the memorylimit to 7 GB so the solver only used the RAM and still with the same performance in the processor. Any ideas about the bottleneck? As I said earlier it works at 100% for the first hours or so . Thanks very much for any answers! Our plan was to overclock it but we can't even get it to work at normal speed yet!

  • Finding bluetooth link key in Win7, to double pair a device on dualboot computer

    - by Ilari Kajaste
    How can I dig up the bluetooth link key for a paired device in Win7? Is this something that is dependent on the bluetooth stack I'm using (Toshiba), or is there a generic place to store these in Win7? Note: I'm not talking about the six-digit code usually typed by the user during pairing - that is worthless since it's discarded after pairing process. What I mean is the 128-bit link key that the devices exchange during pairing, and use thereafter to encrypt all their bluetooth traffic. Background: I dualboot Win7 / Ubuntu on my laptop, and I would like to have my phone paired to both OS's. Since the dualbooting computer has only one bluetooth adapter and thus only one bluetooth address, I cannot do two pairings to the phone, since on the second pairing (windows) the phone just replaces the previous pairing (linux) to the same bluetooth address. A thread on Ubuntu forums pointed me to what I have to do - pair first on linux, then on windows, and then replace the link key on linux side with the one windows negotiated. I can find the linux side pairing key from /var/lib/bluetooth/[BD_ADDR]/linkkeys - no problems there. However, on windows side I can't find the key. According to the forum post, on windows side the key should be in SYSTEM\ControlSet002\services\BTHPORT\Parameters\Keys\[BD_ADDR] but while that registry key does exist, it has no subkeys. (And a similar registry path in ControlSet001 didn't have any subkeys either.) One thing I've been instructed to do is to capture all events during pairing with Sysinternals Process Monitor. I did this, but I haven't been able to find any useful information from the captured events, not even by exporting the data to a huge XML and grepping that with the BD_ADDRs (with or without colons). So how could I find the link key for a paired device in Win7? Some reference information: Wikipedia: Bluetooth, Security Now: Bluetooth security

  • Network card shuts down when stressed

    - by user142485
    I have a network card that functions fine with light use, but quits functioning after heavy use. I replaced it with a brand new one and still have the same issue, also updated drivers. It is a wired D-Link card. The Internet seems fine for a small amount of web browsing but when I run a bandwidth test it starts out fast and slows quickly until the card completely quits; I have a constant ping of the gateway going while I run this and it starts timing out after a couple seconds into the speed test. The card will stay on and the data light on it still flashes some but I cannot ping the gateway or anything else until the computer is rebooted. When I boot into safe mode I can browse and run the speed test fine with no problems. I am guessing that this is probably some program that is loading in regular mode but not safe mode that is causing the issue? I have very limited software (turned off av and firewall) on the computer but I am thinking that I'll just have to start eliminating start-up programs and see if that helps. This is on Windows 7 if that makes any difference. Anyone had a similar issue or have any other suggestions/ideas for narrowing down this problem?

  • Certain websites redirect to 127.0.0.1. How do I fix this?

    - by Dian
    Facebook and Youtube in particular. Tried nslookup the address shows as 127.0.0.1. Checked the HOSTS file, it's fine. Ran Malwarebytes' Anti-Malware (didn't find any problems) and SpyBot Search and Destroy (found 1 problem). (Not sure if the Spybot made this improvement) now pinging youtube shows the correct address (74.125.71.91) but the browser still says: Connection to 127.0.0.1 Failed The system returned: (111) Connection refused Tried ipconfig /flushdns but there are no changes. Switched to another user but the results are the same. hosts file: # Copyright (c) 1993-2009 Microsoft Corp. # # This is a sample HOSTS file used by Microsoft TCP/IP for Windows. # # This file contains the mappings of IP addresses to host names. Each # entry should be kept on an individual line. The IP address should # be placed in the first column followed by the corresponding host name. # The IP address and the host name should be separated by at least one # space. # # Additionally, comments (such as these) may be inserted on individual # lines or following the machine name denoted by a '#' symbol. # # For example: # # 102.54.94.97 rhino.acme.com # source server # 38.25.63.10 x.acme.com # x client host # localhost name resolution is handled within DNS itself. # 127.0.0.1 localhost # ::1 localhost ipconfig all: Connection-specific DNS Suffix: DNS Servers: 10.1.1.30 208.67.220.220
