  • How to setup a hyper-v domain with internet access

    - by fynnbob
    First off let me say that I'm not a network admin or server guy, I know very little about that stuff. What I'm trying to do is setup a virtualized domain using hyper-V. Here is the configuration: Physical Server: 4Mb RAM Windows Server 2008 R2 running Hyper-V Virtual Environment: One Domain Controller running Windows Server 2008 R2 One Client running Windows Server 2008 R2 I have been successful in setting up a virtual domain controller and adding a virtual client to that domain controller but I'm stuck at trying to give the virtual Environment Internet access. I can give the client VM Internet access if I remove them from the virtual domain but once I add them back to the virtual domain, Internet access is gone. I've read articles describing many different ways this can be done (using RRAS with NAT, using a wireless connection, etc...) but all of those articles only cover a small piece of the setup and also seem to be geared towards people who know there way around networking and servers which I don't. I'd like to know more but my thing is software development and I have my hands full trying to keep up with everything in that realm. I simply want to setup a virtual domain with Internet access for testing. Can anyone point me to any "for Dummy's" type information on how to setup this type of environment or can anyone provide this kind of step-by-step help. Any help would be very much appreciated.

  • Sudden and frequent hangs on desktop computer: mobo or CPU fault?

    - by djechelon
    I have a desktop computer equipped with an ASUS Crosshair 2 Formula and a Phenom x6 3.2GHz CPU. My problem is that often the computer will hang all of a sudden, completely stopping responding. When that occurs, reset key is inoperative and power button turns the computer off but is unable to turn it back on. I have to physically disconnect power cable. The problem can occur anytime, when I'm booting Windows, when I'm logging in, when I'm listening to a song, when I'm browsing Internet, etc. It always occurs after very few minutes of 3D gameplay I thought it was a video card fault. I had 3 8800GTX so I could try all combinations of them: didn't fix I thought it was a RAM problem: I tried running with only a subset of my DDR2 banks but didn't fix. Almost every time I have to reset and reconfigure BIOS (without AHCI, Win7 won't boot, so I need to restore a few things). If I enable AMD Live, Cool&Quiet or other things from CPU configuration menu I'll be sure that the computer won't reach Windows desktop in 99% of cases (it randomly hangs somewhere in the boot process or even in the BIOS POST). Another interesting thing is that during the POST process the computer always takes unusually long time detecting USB devices (LCD POSTer shows USB INIT), and I've also tried disconnecting all USB devices but didn't take less time to POST BIOS revision is 2702, the latest. Today I found a different behaviour once: during boot screen I got a BSOD with error Stop 0x00000101 A clock interrupt was not received on a secondary processor within the allocated time interval, and this is usually related to overclocking, but I never overclocked my CPU. Judging from the description of my problem, hoping someone had the same and fixed, and since I don't have a spare CPU or motherboard for replacement, I'd like to ask if you think this is a problem with faulty CPU or faulty motherboard, and if I can perform additional tests (I mean software tests because of my lack of spare components) to identify the component to replace.

  • Configure samba server for Unix group

    - by Bird Jaguar IV
    I'm trying to set up a samba server with access for users in the Linux (RHEL 6) "wheel" group. I am basing smb.conf off of the example here where it goes through the [accounting] example. In my smb.conf I have [tmp] comment = temporary files path = /var/share valid users = @wheel read only = No create mask = 0664 directory mask = 02777 max connections = 0 (rest of the output from $ testparm /etc/samba/smb.conf is here). And groups `whoami` returns user01 : wheel. When I use the following command from another machine (Mac OS) as the Linux user (user01): $ smbclient -L NETBIOSNAME/tmp it asks for a password, I hit return without a password, and get: Enter user01's password: Anonymous login successful Domain=[DOMAIN] OS=[Unix] Server=[Samba 3.6.9-151.el6_4.1] Sharename Type Comment --------- ---- ------- tmp Disk temporary files IPC$ IPC IPC Service (Samba Server Version 3.6.9-151.el6_4.1) But when I try $ smbclient //NETBIOSNAME/tmp I try entering the password I use for the Linux login, and get a bunch of stuff logged, including check_sam_security: Couldn't find user 'user01' in passdb. ... session setup failed: NT_STATUS_LOGON_FAILURE (I can give more logging information if it would be helpful.) I can't find a reference to more steps I need to add group users in the resource. Should I be manually adding samba users from the group somehow? Thank you

  • Periodic internet connection drops

    - by sterlingholt
    My setup is a dsl modem, and a dlink di 524M router. I'm also using a Witopia VPN which runs through OpenVPN. I've been having trouble with the internet connection dropping very frequently. It comes back shortly, without even a router/modem/computer restart. This happens as frequently as every ten minutes. Occasionally (not often) it will last as long as an hour or two without dropping. When it drops, I can get it back almost immediately by clicking Reconnect in the OpenVPN GUI and letting that do it's thing. It's worth noting that I'm in China. Calling support is a bit difficult because of that. Also I don't really understand all of the router's software, although I've got it generally figured out. I've tried a bunch of stuff, attempts to diagnose and/or fix the problem. No success with any of the following: I've power cycled both the modem and the router. I've tried an ethernet connection to the router. I've connected without the VPN. I've disabled IEEE authentication on all connections. I've checked for viruses. I've tried lifting it off the ground so as to prevent overheating.

  • HP Proliant DL380 G4 - Can this server still perform in 2011?

    - by BSchriver
    Can the HP Proliant DL380 G4 series server still perform at high a quality in the 2011 IT world? This may sound like a weird question but we are a very small company whose primary business is NOT IT related. So my IT dollars have to stretch a long way. I am in need of a good web and database server. The load and demand for a while will be fairly low so I am not looking nor do I have the money to buy a brand new HP Dl380 G7 series box for $6K. While searching around today I found a company in ATL that buys servers off business leases and then stripes them down to parts. They clean, check and test each part and then custom "rebuild" the server based on whatever specs you request. The interesting thing is they also provide a 3-year warranty on all their servers they sell. I am contemplating buying two of the following: HP Proliant DL380 G4 Dual (2) Intel Xeon 3.6 GHz 800Mhz 1MB Cache processors 8GB PC3200R ECC Memory 6 x 73GB U320 15K rpm SCSI drives Smart Array 6i Card Dual Power Supplies Plus the usual cdrom, dual nic, etc... All this for $750 each or $1500 for two pretty nicely equipped servers. The price then jumps up on the next model up which is the G5 series. It goes from $750 to like $2000 for a comparable server. I just do not have $4000 to buy two servers right now. So back to my original question, if I load Windows 2008 R2 Server and IIS 7 on one of the machines and Windows 2008 R2 server and MS SQL 2008 R2 Server on another machine, what kind of performance might I expect to see from these machines? The facts is this series is now 3 versions behind the G7's and this series of server was built when Windows 200 Server was the dominant OS and Windows 2003 Server was just coming out. If you are running Windows 2008 R2 Server on a G4 with similar or less specs I would love to hear what your performance is like.

  • Windows 7 BSOD on startup

    - by Cristy
    I got a BSOD today after getting home from 11 hours of work... It seems to work in SAFE MODE (sometimes, not always) The BSOD says: SYSTEM_SERVICE_EXCEPTION STOP: 0x0000003b WimFsf.sys - Address FFFFF88001A6B76B base at FFFFF88001A600000, DateStamp 4a5bc362. Sometimes it shows the welcome screen, shows the destkop for a few seconds and then BSODs Already did: unplugged all the USB devices reset the CMOS I haven't installed any new software recently. What should I do? EDIT: I've managed to get into safe mode and it seems to works fine. When I go into normal mode it shows the desktop then it freezes... Is it more likely to be a software or hardware problem? EDIT2: I've managed to get into normal mode by disabling all the non-microsoft services & startup programs. One more thing: When I shut down my PC, on the "Logging off" screen appear some artifacts. I don't think it's because of my graphics card cause I've opened Black OPS and it worked fine. It's so strange... It still BSODS on startup (but there a ~=10% that it will not), and when it doesn't BSOD's it works fine...

  • Enabled Network Discovery on Server, and now VNC and Squeezebox clients don't work

    - by Mike Hanson
    I've recently setup a Windows Server 2008. It's running an email server, Squeezebox server, MS SQL Server, etc. I'm doing remote maintenance with UltraVNC. I had everything working fine. Then the server needed to access a network share on another machine, and I was prompted to turn on network discovery, which I did. I chose the Home rather than Public option. Since doing that, some things have stopped working, while others are still fine. Shared folders and the the Email services (ports 25 and 110) are still accessible. VNC (port 5900) and Squeezeboxes (port 9000) no longer work. Here's what I've tried to try to solve the problem: Checked the network discovery settings, to see if anything looked strange. Checked the firewall settings, and those ports appear to be open. Also in the firewall settings, the entries for Private domain Network Discovery were all on, but the Domain/Public ones were off. I tried turning those on. In the services, turned on Function Discovery Resource Publication and SSDP Discovery. Any other suggestions?

  • Nginx/puma rhel unix socket permission error?

    - by Kevin Brown
    When I try to start my puma server, I get the error: /.rvm/gems/ruby-2.1.1/gems/puma-2.9.0/lib/puma/binder.rb:275:in `initialize': Permission denied - connect(2) for "/var/run/nvhbase.sock" (Errno::EACCES) My sites-available/nvhbase.conf file: upstream nvhbase { server unix:/var/run/nvhbase.sock; } server { listen 80 default_server; server_name 207.131.132.219; root /home/vf032500/dev/nvh/public; location / { proxy_pass http://unix:/var/run/nvhbase.sock; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection $connection_upgrade; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-Proto https; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_redirect off; } } I don't know a lot about unix sockets and everything works fine using tcp/puma default. My rails app is in my user directory. Is that the problem?? socket is starting in /var/run--I can start in /tmp, but I've heard that's bad practice? Provided I start the server in /tmp, I then can't access it via the server's ip--then what? I'm happy to provide any needed info, I just don't know a whole lot about server/nginx/puma.

  • Running $ORIGIN linked binaries from setuid scripts on linux

    - by drscroogemcduck
    I'm using suidperl to run some programs that require root permissions. however, the runtime linker won't expand library paths which contain $ORIGIN entries so the programs i want to run (jstack from java) won't run. more info here There is one exception to the advice to make heavy use of $ORIGIN. The runtime linker will not expand tokens like $ORIGIN for secure (setuid) applications. This should not be a problem in the vast majority of cases. my program looks something like this: #!/usr/bin/perl $ENV{PATH} = "/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/java/jdk1.6.0_12/bin:/root/bin"; $ENV{JAVA_HOME} = "/usr/java/jdk1.6.0_12"; open(FILE, '/var/run/kil.pid'); $pid = <FILE>; close(FILE); chomp($pid); if ($pid =~ /^(\d+)/) { $pid = $1; } else { die 'nopid'; } system( "/usr/java/jdk1.6.0_12/bin/jstack", "$pid"); is there any way to fork off a child process in a way so that the linker will work correctly.

  • Moving server room to another part of the building

    - by PHLiGHT
    This question is a bit different than the typical we are moving our server room to an off site location or we are moving the whole office to a new building. Management wants to add some more office space and to do so they want to move the server room to another location. The server room has Verizon smart jacks, a few servers, PBX and all the office network drops go into this room. I'm going to go over there to scout out an alternate location for the equipment because that is still TBD. This sounds like quite a pain since the Verizon equipment for our MPLS will need to be moved (never done that) and the office jacks will need to be re-run. How do you handle the jacks? I was thinking of keeping them in the same location and having new wall plates put in with half the ports going to the current location and the other half to the new location. Or do you think that 40 drops could just be done over the weekend so the old stuff would be ripped out and replaced with the new? Currently the wiring is a mess so this could be a blessing in the long run.

  • Problem Uninstalling Microsoft Internet Explorer

    - by Roger F. Gay
    On Windows Vista Home Premium (x64) I am trying to uninstall Microsoft Internet Explorer. The procedures explained all over the web involve going through the control panel to Programs and Features. If MSIE is listed there, then uninstall in the usual way. If it is not listed there, click Turn Windows features on and off and deactivate it there. But Internet Explorer is not listed in either place. Background: I initiated some process in MSIE a couple of months ago that caused all web pages to no longer save login information or remain logged in when requested. As you can tell from the way I described that, I don't remember what it was and have no way to simply reverse it. I had a few problems with .NET Framework as well. So, I've uninstalled all browsers except MSIE and uninstalled .NET Framework. I've reinstalled .NET Framework and all other browsers. I have not been able to uninstall MSIE. Have Tried: I tried installing over the existing installation, but auto-update must be keeping it nicely up to date. The attempt simply produced an information window telling me that my current version is more up-to-date than the new version I tried to install.

  • VirtualBox: using physical partition as virtual drive

    - by Hamman Samuel
    Background: I am using VirtualBox installed on Windows 7. From within VirtualBox I am using Xubuntu as a virtual OS. The reason I chose this approach is so that I don't have to keep turning off Windows and rebooting from Xubuntu every time I needed to switch OSes. And VirtualBox's seamless mode is pretty amazing to allow me see Xubuntu and Windows 7 all in one screen. Issue: Now I am thinking of a way to have Xubuntu more integrated into my system. By this I mean I want to have a physical partition for Xubuntu. But I want to still have the feeling of the seamless mode. Question: So finally, my question is: is it possible to load a partition in VirtualBox as a virtual OS? Case examples: Ideal scenario would be: I physically boot up and login to Windows 7. Now I want to access Xubuntu, so I load VirtualBox and access my Xubuntu partition without rebooting. And the other way around too, i.e. I boot up the system, login to Xubuntu, and can access the actual Windows 7 partition through VirtualBox. Other info: Please note that I am not talking about getting access to files, as I have a completely separate partition for my files, and am very familiar with VirtualBox's Shared Folders option.

  • How does one skip "Windows did not shut down successfully" in Win7-64?

    - by XenonofArcticus
    Migrating an app from an expensive and unreliable dedicated embedded x86 box running WinXP-embedded to COTS hardware (Dell E6410 laptop) running normal Win7-64. At this time, it's not feasible to deploy using Windows 7 embedded. The problem is, that the system is still sort of "embedded". The power could shut off at virtually any time without prior warning. We've stripped the OS down and removed the battery capability so that it will power down as desired. The app never writes to the disk, so it's not like we're going to corrupt anything terribly. The system is essentially idle after our app is up and running (with the exception of some computation, graphics, and TCP/IP and serial communications) so the OS enters a pretty stable state rather quickly. After a power-loss however, it rightly complains that Windows did not shut down successfully and presents the user with the Windows Error Recovery text screen. If left alone, it does eventually move on booting just fine, but we'd like to skip that step if possible. WinXP-embedded is designed to do this automatically, so I know it's possible. I've looked at the Kernel Switches but I didn't see anything documented for "Skip Windows Error Recovery". I've also read extensively on the startup process: http://homepage.ntlworld.com./jonathan.deboynepollard/FGA/windows-nt-6-boot-process.html I know I can disable the auto chkdsk in the registry, but that's not the same thing either. So, how do I streamline the boot process to not hassle the user about a situation that will be the regular normal situation?

  • Linux wireless disconnect every 20 minutes

    - by james
    My laptop uses CentOS 6.3 with kernel 2.6.32-279.el6.x86_64. My wireless adaptor is Intel Corporation Centrino Wireless-N 1000. My wireless connection always get off after about 20 minutes. The network applet shows the connection is still on with good signal strength, but I just cannot load any web pages even the configuration page of the wireless router. The problem will continue until I disable and reconnect the wireless. Other devices like my cell phone uses the same wireless network without the problem. Even yesterday I'm using the same laptop with Fedora 17 without this problem. I also searched the internet and someone said running services NetworkManager and network simultaneously may be a problem. But I cannot stop any one of them because: if I stop network and start NetworkManager, the network service will start automatically; if I stop NetworkManager and run network, it says "Device does not seem to be present, delaying initialization." when trying to bringing on the wireless. What shall I do to get rid of the problem? Thank you very much!

  • How to play 24 fps video smoothly on a 60Hz display?

    - by netvope
    I use mpc-hc to play videos on Win7 x64. With the default settings (#1), video playback is great most of the time. But for panning shots, playback is not smooth. I stepped through the video frame by frame and found that the panning movement is smooth (e.g. each frame shifts horizontally by 10 pixels), so the problem is how the 23.976 fps video is interpolated to 60Hz. The judder looks like what would be caused by a "2:3 pulldown", where the frames are played unevenly like: frame 1, 1, 2, 2, 2, 3, 3, 4, 4, 4, etc (#2) Using "optimal renderer settings" (#3) instead of the default disables the Aero theme and causes tearing. Setting my LCD display to 50Hz may have improved the judder slightly (but I can't really tell). My display does not support 24Hz or 48Hz, and forcing them in the Nvidia control panel gives blurry screen. I've tried other video players (VLC and KMPlayer), the ReClock Directshow Filter, video files from different sources (#4), turning on/off DXVA, and a computer with a different GPU, but the judder in the playback is similar. None of them solved the problem. So, how can I play 23.976 or 24 fps video smoothly on a 60Hz display? I think a video player could make the video smoother by doing linear interpolation, such as: 1. 100% frame 1 2. 60% frame 1 + 40% frame 2 3. 20% frame 1 + 80% frame 2 4. 80% frame 2 + 20% frame 3 5. 40% frame 2 + 60% frame 3 6. 100% frame 3 7. 60% frame 3 + 40% frame 4 .. etc Can any existing video player do this? Footnotes: (#1) Video renderer: EVR Custom Pres. (#2) This example converts a 24 fps video into 30 fps (#3) View Renderer settings Reset Reset to optimal renderer settings (#4) The files I have are all H.264 mkv files, but I don't think the file format/encoding matters.

  • VMware ESXi 4.1 snapshot of server 2008R2 machine generates 2 indentical snapshots

    - by Peter
    I have 2 VMs that are failing to get veeam backups, and it appears that the culprit is vmware snapshots. We are running Vsphere ESXi 4.1 build 320092, we have multiple server 2008R2 machines that take snapshots fine, but when with these two VMs when I take a snapshot I get 2 identical snapshots a few seconds apart. The snapshot manager only shows 1 snapshot, but there are 2 files 1 number off, that are identical sizes. There is only one disk on each VM, so that isn't the problem. Has anyone seen this behavior before and know how to fix it? Here are the files after a bad snapshot VM-XXX-000001-ctk.vmdk VM-XXX-000001-delta.vmdk VM-XXX-000001.vmdk VM-XXX-000002-ctk.vmdk VM-XXX-000002-delta.vmdk VM-XXX-000002.vmdk VM-XXX-2a659dbf.hlog VM-XXX-2a659dbf.vswp VM-XXX-Snapshot286.vmsn VM-XXX-aux.xml VM-XXX-ctk.vmdk VM-XXX-flat.vmdk VM-XXX-vss_manifests286.zip VM-XXX.nvram VM-XXX.vmdk VM-XXX.vmsd VM-XXX.vmx VM-XXX.vmxf vmware-20.log vmware-21.log vmware-22.log vmware-23.log vmware-24.log vmware-25.log vmware.log VM-XXX-000001.vmdk and VM-XXX-000002.vmdk are the exact same size.

  • 500 Error when logining into subdomain using codeigniter

    - by itsdanprice
    I have a website that has been setup and working fine for ages. It's built using Code Igniter. It's run using .htaccess files to restrict access and hide urls. All fine. Until a couple of days ago when we try to access http://admin.dealersupport.co.uk we get a 500 error (this is the back end of the site, held in a seperate subdomain.) Nothing else has changed on the server. I have tried restoring from a back up from when I know it was working. The problem persists. The only thing I can think of is that we recently upgraded to Plesk 11.0.9 and since then we have been seeing some Apache instabilities. The only thing that is thrown up by the error logs is this: Wed Nov 21 08:40:17 2012] [error] [client 94.31.24.129] Options FollowSymLinks or SymLinksIfOwnerMatch is off which implies that RewriteRule directive is forbidden: /var/www/vhosts /dealersupport.co.uk/admin/index.pl, referer: http://admin.dealersupport.co.uk/login I have now added this to my .htaccess files Options +FollowSymLinks +SymLinksIfOwnerMatch RewriteEngine On And that seems to have eliminated that error from the error logs, but we are still getting a 500 error when we have logged into the backend. Can anyone help?

  • Sync desktop Mac environment to laptop

    - by Andrew Vit
    I spend the majority of my time working at my desktop Mac, which I have configured for my web development environment. My spouse has a MacBook for casual use, and I occasionally steal it back when I need to work off-site, or when travelling. The question is how to best synchronize the two so I can switch between them more readily. I've solved a few obvious things by using online services: Email is hosted on IMAP. Working files are in Dropbox. Source code is managed in git. However, the following are things I always miss when jumping on the laptop: Installed Applications (current versions) Installed libraries & utilities (/usr/local) Apache VirtualHosts & other configurations (/etc) Disk image files for VMs My current method is to connect the MacBook via Firewire target mode and rsync the /Users/me home directory, and then cherry-pick the other items I need from Applications, /etc and /usr/local. The problem with this method is that it can be very time consuming due to things like my virtual machine image files, cached emails, etc. How can I make this faster & easier? Can you recommend a solution for configuration management (so I can repeatably install & configure the same software on both), or synchronization (so I can bring the MacBook up to date nightly, over our home network)?

  • Cloning a NAS drive which hosts a SQL Server DB

    - by Adrian Hand
    We have a system in the field running a server application which is suffering with major performance issues. The system in question has 2 onboard 300gb sas drives in RAID 5 from which it boots Windows Server 2003, and a 6tb buffalo terastation NAS unit (also RAID 5) to which the server app does all of its reading and writing. I believe the terastation is the source of all our woes. Whilst under load, reads and writes tick by at something of the order of 1meg/sec, though the network in question is hardly utilised. The terastation contains various data, but crucially hosts a full instance worth of SQL Server .mdf and .ldf files (master etc - the whole shooting match) I wish to stop all the services on the server, then take everything on the terastation and essentially clone it to some alternative onboard storage, so as to eliminate the terastation from the equation as far as poor performance is concerned. ie the terastation is currently drive D: - I want to copy everything off and then have the duplicate assume the drive letter so that as far as the software is aware, nothing is different. This is tricky because of the mdf and ldf files - everything else will work with a straight up file copy. Can anyone suggest a means to achieve what I am describing? Many thanks!

  • Connecting a laptop to a TV via HDMI

    - by Madmartigan
    I just bought a new Dell XPS17 laptop (Win7) that only has HDMI output. My last 2 laptops had VGA, which I used to connect to my Sony Bravia 32" TV with no issues, but with the HDMI it's been quite a headache. Drivers for display adapters have been updated to the latest versions: Intel(R) HD Graphics Family NVIDIA GeForce GT 550M I went to a store and plugged in to 4 different TVs from different manufacturers. A sales rep and I spent about 30 minutes being baffled by the results (which are the same as my current TV): Extreme buggy behavior in the Nvidia and Windows display/resolution control panel Can not extend or duplicate displays, can only select one Third and fourth output devices "randomly" detected by the Windows control panel Could not get the screen to fit the output (edges cut off on all sides by about a half inch) Resolution and colors less than perfect. Artifacts around text. Display "randomly" cuts out Defaults to TV output only when plugged in Can not change resolution on either device when connected No audio from the TV Plugged in to 3 monitors from different manufacturers: Defaults to duplicated displays when plugged in Everything works perfectly So far, four people have gone through all the settings in the latop with no luck. I had similar, but not exactly matching results with a different laptop. I'm using the Sony Bravia currently at home, but in order to get it to work I have to turn on the laptop, wait until the display shows up on it, close the lid, then cycle through each output channel on the TV until I come back around to the HDMI port again, but still I have the symptoms described above. However: Once in a while, it just works. Sometimes, seemingly randomly, the output fits the screen perfectly. Sometimes the audio comes through the speakers too, but not always. Usually my screen saver "Mystify" will come up with a message that it cannot be displayed due to a limitation of the video card, but then sometimes it works fine. These 3 things seem to be independent of each other and don't always happen together. So, is there any way to get the laptop to output correctly to a TV, or is it just not meant to be?

  • Why is writing to my external hard drive slow, while benchmarks show fast writing?

    - by matix2267
    I have an iOmega eGo 320GB portable drive connected through USB2.0 to my laptop running Windows Vista. It's been working fine for quite some time until recently it became very slow when writing e.g. when copying ~300MB movie over to the drive at first it is extremely fast but it actually doesn't write it only puts in cache and then hangs on last 10-20MBs for about a minute. When copying larger files it's the same story: starts fast but then slows down to ~5MB/s (sometimes even slower down to 2MB/s). Strange thing is that I have always had caching disabled for this drive (it was disabled by default and I never bothered changing it). At first I thought that the disk is dying so I checked S.M.A.R.T. values and everything is fine there. I also run chkdsk and it seemed to fix the problem - it worked fast for a few minutes but then it slowed down again. I also tried plugging it into another USB port - no difference. Additionally I noticed that reading under certain circumstances is sometimes slower e.g. loading times for some games are ~10 times longer, whereas simple copying files from this drive to my internal HDD is fast. I ran a speed benchmark using CrystalDiskMark with a 5x100MB run and strangely got these results: read write (MB/s) Seq 33.05 28.25 512k 17.30 15.27 4k 0.267 0.372 4kQD32 0.510 0.260 This is different from what most other people have (I've found many threads about slow disk write while googling but all of them were slow on benchmarks too) which is why I decided to post this problem here. BTW most of the time when writing (or sometimes reading) the activity led is mostly idle (blinks a while and then stops for longer, sometimes has slower blinks ~1 sek, sometimes goes off for a few seconds - extremely long blink :) ) but when benchmarking, defragmenting or just reading (copying from this drive, installing apps from installers there, watching HD videos) it is blinking really fast (like it should) and there are no slowdowns. It shouldn't be driver issue unless stock Windows drivers have some issues I'm not aware of.

  • Seemingly random network connectivity.

    - by AngryHacker
    This has been driving me nuts for a while. When I turn on the PC (which has a wired Ethernet connection), it cannot be accessed by other computers on the network. In other words, inbound connections do not work. The firewall is disabled. The PC itself can hit up anything it wants just fine. By process of elimination, I've figured out that checking or unchecking the Eaclift driver in the properties for my network connection restored the inbound connection. I do not know what Eaclift driver is or does or how it even got on my PC (e.g. I am not allowed to uninstall it either). And it does not matter whether it's on or off - I just need to toggle it to restore connectivity. One other thing that happens when I toggle the Eaclift driver, is than an Internet Connection icon appears in the Network Connections and it was not there before. Can someone shed some light as to what is going on? How to fix it so that I don't have to deal with this insanity?

  • Nginx order of servers

    - by scrat
    I have 3 sites on my server. All are running on gunicorn and use unix sockets to communicate with nginx which routes requests. I got three records in nginx.conf like: server { listen 80; server_name site1.com; location / { proxy_pass http://unix:/tmp/site1.sock; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } } For site1, site2, site3. If they are ordered as config for site1 goes first, and then goes config for site2 and site3 everything works good. But when I change the order for example to site2, site1, site3, then site1 becomes routed to site2. What am I doing wrong? Full server nginx.conf before servers configs: user www-data; worker_processes 4; pid /var/run/nginx.pid; events { worker_connections 768; # multi_accept on; } http { ## # Basic Settings ## sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 65; types_hash_max_size 2048; include /etc/nginx/mime.types; default_type application/octet-stream; ## # Logging Settings ## access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; ## # Gzip Settings ## gzip on; gzip_types text/css application/x-javascript text/x-component text/richtext image/svg+xml text/plain text/xsd text/xsl text/xml image/x-icon;
