• Certain clients (IP range) can not ping server

  - by Logman

  I just virtualized a Windows 2003 Server SP2 x32. The server contained our help desk server (Spiceworks) and our anti virus management server (ESET RAC). The host computer actually contained the virtualized server originally; I created the vhd and then I wiped this system clean and installed Windows 2008 R2 x64 Datacenter and added the virtualized 2003 onto the Hyper-V 2008 R2 Server. I got the server running fine except for... certain ip ranges. Local clients can get updates from the AV server from my 192.168.180.xxx & 192.168.181.xxx BUT NOT from any 192.168.182.xxx, 192.168.183.xxx, 192.168.184.xxx etc... I can not ping the server from any clients except for the 180. & 181. ranges. Now I created 2 other virtualized servers (win2008 & a win7 pro) and they exist on the same virtual host as the 2003 server. And at first I could not ping those until I went to the "\Network and Sharing Center\Advanced sharing settings" and Turned On File and Print Sharing. Then I could ping and access those virtualized guests. Win2003 server isn't quite the same. But I am sure I have it on. But now when I ping from a client on one of those ranges that would not work I get this: As you can see the ping leaves our network. We have 2 ad/dns servers (one 180. & the other in the 181. range). Is it DNS? Both AD/DNS servers are Windows 2003. And we plan on upgrading both to 2008 R2 within a month or two but I need to fix this issue pronto (esp the AV end). btw, I did rename that 2003 Server (Spiceworks/AV) hostname. And I tried a CNAME. But I do not think that is the problem. EDIT: OR because this server existed on this hardware/computer before becoming virtualized?

• Forms authentication failed between web server and sql server

  - by Matt Bear

  I've actually found the solution, but I'm trying to understand why it failed, and why my solution fixed the problem. We have an application that uses forms authentication between a web server and sql server, web server runs server 2008, sql server runs 2008 r2, and sql server 2008. In august the sql server was patched with .net 3.5.1, the web server was untouched, and the forms authentication continued to work. 1 week ago we virtualized the web server onto our vSphere server because of failing hardware. Afterwards the form authentication failed with event code 4005, detail code 50201, The ticket supplied was invalid (on the sql server). In fact the sql server started generating Schannel errors and began blue screening 3-4 times a day. At this point I touched the sql server for the first time(ever), the errors were non specific, any reference to them I could find had to do with either zone alarm(which we don't run), or memory errors. So I applied service pack 1, which stopped the blue screening, but did not fix the forms authentication. At this point we had a work around, so we put it on the back burner while we completed another project, and I was able to get back on it last night. First thing was to adjust some code in the webconfig file on the sql server, nothing, next was regenerate and change out the machine key, still no change. Update the DNS servers, no change. Finally I went through and installed all windows updates, two reboots, (over RDP installed a network card driver which failed, and did not have my server room key, that was fun). After that, forms authentication was working again. And the sql server stopped generating as many errors, I've gotten two schannel errors since then. In short, forms authentication began failing when the web server was cloned onto a virtual machine, which caused the sql server to blue sceen? and forms authentication to fail. And could only be fixed by applying patches to the sql server?(I'm wishing I had patched the servers one at a time so I could know for sure which patch on which server fixed it). My question is why did it fail, and why did patching fix it? I hate fixing something without fully understanding the why and how.

• Root directory permissions on Mac OS X 10.6?

  - by Agos

  Hi, I was wondering if it's normal that the root directory / should be owned by “root”. I get asked for my password every time I want to do something there (e.g. save a file, create a directory) and I don't remember this happening before (though this may just be my faulty memory).

• Troubleshooting major performance issue: Is culprit Intel RST, Hard drive, or something else?

  - by Sean Killeen

  The Setup I have the following components that come into play in this situation: ASUS P8Z68 V/PRO motherboard a RAID1 configuration (1x 1TB drive, 1 x 2TB drive -- I explain below), accelerated with an SSD using Intel's RST software, and 1 TB drive standing by as a spare. Core i7 2600k 32 GB RAM Windows 8.1 This box was designed to be beast, and until just recently, was very good at being just that. What's Happening The system has slowed to a crawl whenever it touches the disk. Things appear to work at normal speed when dealing with memory. For example, typing this is fine, but saving it to disk from notepad gave me a 5-7 second pause when clicking save. The disks appear to be at 100% all the time (e.g. the light on the disk access on the PC is solidly on -- not even any flashing) In ProcExp it appears that the disk is barely being utilized at all: Intel RST reports that everything is fine: Other Details Prior to this happening, RST had reported that my drives were failing (one went bad, one was throwing SMART events). This made sense; they were at the tail end of their warranty and the PC is on almost all the time. I RMA'd the drives via Seagate. In the meantime, I'd purchased a 2TB drive because I didn't realize that the 1TB drives were under warranty. I figured I'd replace the other 1 TB drive with another 2 TB when it died but then discovered the warranty. AFAIK, I haven't done any major updates since 8.1 and it worked fine after those. Question(s) How can I troubleshoot this? What is the best way to try to figure out why disks are being maxed out despite the OS reporting barely any disk usage and that everything is OK? Given the failures, etc. that I describe above, is it possible that the problem could be the I/O on the motherboard itself? If so, how would I even be able to diagnose it? I'm betting the drives that Seagate gave me are refurbished (didn't think to look; that's dumb). Is it possible that the same model drive, refurbished, could somehow cause this? In terms of how RAID1 works, is it possible that one drive is "falling behind" somehow, and that the RAID1 is constantly trying to fix the mirroring? If so, this seems like Intel RST would report on it, but I wanted to consider it as an option.

• Problem with authentication of users via IE when using "host header value"

  - by Richard

  Hi, I'm trying to set multiple web sites up in an IIS 6. I've got a working virtual site residing under the default web site, but if I create a new web site in the IIS and asign it a host header value, let it point to the very same file structure as in the prevoiusly mentioned site and finally asign windows integrated security only to the site - I still cannot log in to the new site using MSIE 6 or 8 but FF 3.5 works fine.

• HOSTS ignored when disconnected [closed]

  - by Synetech

  Problem I’m seeing a strange and extremely frustrating problem. Any system that is not connect to the Internet (Windows 7 shows the no Internet access icon because it cannot constantly ping Microsoft’s servers) cannot even access locally hosted servers. Hypothesis The problem appears to be that the HOSTS file is not being used to resolve DNS entries when there are no active NICs. Tests / Reproduction You can reproduce it as so: Disconnect a system from the Internet (make sure all wired and wireless connections are disconnected). If necessary, add an entry to the HOSTS file (e.g., 127.0.0.1 foobar or 127.0.0.1 foobar.com) Open a command-prompt Type ping foobar or ping foobar.com Observations The screenshots below show a clear and demonstrative example. In the first snap, a laptop is connected to a router wirelessly. The HOSTS file has only three entries and they resolve just fine. In the second snap, the wireless radio is turned off, so the entries in the HOSTS file are ignored. Moreover, notice that pinging localhost still works even without any active NICs (as does 127.0.0.1), but it is using the IPv6 address (must be hard-coded). You can see the same results in Windows XP with no IPv6 installed, so it has nothing to do with IPv6. I tried pining what should have resolved to 127.0.0.1 while the desktop system (with no wireless NICs) was connected via its Ethernet adapter, then again after pulling the cable from the router and waiting a couple of seconds, then again after plugging the cable back in. The same thing happens if instead of pulling out the cable, the NIC is disabled through software (the [Disable] button in the NIC’s Status dialog or via Device Manager). Conclusions It looks as though the HOSTS file is only being read and used if there is an active NIC, otherwise it is being ignored. This makes some sense in that if there are no active network adapters, then presumably there will not be any network activity, and thus no need to resolve host names via the HOSTS file. This assumption is specious however because it precludes locally hosted virtual servers. The HOSTS file should be used regardless of external DNS server connectivity, otherwise you cannot use simple/consistent/testing-production names for locally hosted servers when not connected to the Internet (for example web servers; help servers for Visual Studio, 3dsmax, etc.; and so on). Question Does anyone know how to force Windows to use the HOSTS file even if there are no active NICs? Appendix Figure 1: While the wireless NIC is connected to the router (the cable-modem is in standby, so no external Internet connectivity). Figure 2: With the wireless radio turned off (the Ethernet port is not unconnected in both cases). Figure 3: Same results in XP with no IPv6

• Python install issue on Mac OS X

  - by Michael Waterfall

  I have been using the standard python that comes with OS X Lion (2.7.2) but I wanted to build a UCS-4 version to handle 4-byte unicode characters better. I had already installed pip and packages like pytz, virtualenv and virtualenvwrapper, etc., and these are installed in /Library/Python/2.7/site-packages. My $PATH is /usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin. To build a new version of python on the machine (outside of any project specific virtual environments, that will come later), I followed the instructions on this article and managed to build it in /usr/local/bin. The problem is that when I launched a new bash window, I got the following virtualenvwrapper error: Traceback (most recent call last): File "<string>", line 1, in <module> ImportError: No module named virtualenvwrapper.hook_loader virtualenvwrapper.sh: There was a problem running the initialization hooks. If Python could not import the module virtualenvwrapper.hook_loader, check that virtualenv has been installed for VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python and that PATH is set properly. The instructions said to move /usr/local/bin to the top of the /etc/paths file, and since then I've noticed some strange issues. I installed pip into /usr/local/bin and now I have assumed that since I'm working in /usr/local/bin, and the newly installed python's site packages is now located in /usr/local/lib/python2.7/site-packages, when I do pip freeze, it should be empty as nothing is installed there yet. However, pip freeze still reports things installed in the old (OS X) site-packages folder. Here's some info after the build: $ which python /usr/local/bin/python $ which pip /usr/local/bin/pip $ echo $PATH /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin When I uninstall a python package with pip, it removes it from the old site-packages folder as expected. When I install it again, instead of installing it in /usr/local/lib/python2.7/site-packages, it installs it in /Library/Python/2.7/site-packages (verified by attempting to install it again and receiving Requirement already satisfied (use --upgrade to upgrade): pytz in /Library/Python/2.7/site-packages ). How is it getting that path for the old site-packages folder? Why won't it install it in the correct location for the python install it's using? I'm getting several other issues since promoting /usr/local/bin but I think if I understand this I'll be able to get somewhere. Can anyone see what's happening? If you need any more info I'll be happy to provide it.

Software : Plain vanilla 2.6.32.25 kernel, compiled for AMD-64, optimized for NUMA; Debian Lenny userland. benchmarks run : disktest, bonnie++, dd, etc. All give the same results. No discrepancy here. io scheduler used : noop. Yeah, no trick here. Up until now I basically assumed that striping (RAID 0) several physical devices should augment performance roughly linearly. However this is not the case here : each RAID array achieves about 780 MB/s write, sustained, and 1 GB/s read, sustained. writing to both RAID arrays simultaneously with two different processes gives 750 + 750 MB/s, and reading from both gives 1 + 1 GB/s. however when I stripe both arrays together, using either mdadm or lvm, the performance is about 850 MB/s writing and 1.4 GB/s reading. at least 30% less than expected! running two parallel writer or reader processes against the striped arrays doesn't enhance the figures, in fact it degrades performance even further. So what's happening here? Basically I ruled out bus or memory contention, because when I run dd on both drives simultaneously, aggregate write speed actually reach 1.5 GB/s and reading speed tops 2 GB/s. So it's not the PCIe bus. I suppose it's not the RAM. It's not the filesystem, because I get exactly the same numbers benchmarking against the raw device or using XFS. And I also get exactly the same performance using either LVM striping and md striping. What's wrong? What's preventing a process from going up to the max possible throughput? Is Linux striping defective? What other tests could I run?

• SSD Fresh Does Not Start

  - by Jim Fell

  I recently installed a new 60GB SSD as my primary hard drive and re-installed Windows 7 Professional 64-bit. I then installed SSD Fress from Abelssoft to optimize Windows to run on the SSD. It seemed to install okay, but when I try to run the utility, its splash screen appears briefly before it quietly closes. No errors are displayed; the utility just fails to launch. I have run SSD Fresh on another SSD-equipped Windows 7 Pro x64 computer in the past without any problems. Does anyone know what might be preventing the program from running? I tried shutting down the Spybot Resident and disabling the firewall and virus scanner with no luck. I also tried running the tool as administrator; I even tried reinstalling it, running the installer as administrator. No luck. Every time I try to launch the program the Event Viewer logs this same set of errors: Error 4/2/2012 11:35:44 PM Application Error 1000 (100) Error 4/2/2012 11:35:43 PM .NET Runtime 1026 None Error 4/2/2012 11:35:39 PM SideBySide 59 None Error 4/2/2012 11:35:39 PM SideBySide 59 None Error 4/2/2012 11:35:39 PM SideBySide 59 None Error 4/2/2012 11:35:39 PM SideBySide 59 None Error 4/2/2012 11:35:39 PM SideBySide 59 None Error 4/2/2012 11:35:39 PM SideBySide 59 None Error 4/2/2012 11:35:39 PM SideBySide 59 None Error 4/2/2012 11:35:39 PM SideBySide 59 None Error 4/2/2012 11:35:39 PM SideBySide 59 None Error 4/2/2012 11:35:39 PM SideBySide 59 None Error 4/2/2012 11:35:39 PM SideBySide 59 None Error 4/2/2012 11:35:39 PM SideBySide 59 None Error 4/2/2012 11:35:39 PM SideBySide 59 None Error 4/2/2012 11:35:39 PM SideBySide 59 None Error 4/2/2012 11:35:39 PM SideBySide 59 None Error 4/2/2012 11:35:39 PM SideBySide 59 None Error 4/2/2012 11:35:39 PM SideBySide 59 None Error 4/2/2012 11:35:39 PM SideBySide 59 None Error 4/2/2012 11:35:39 PM SideBySide 59 None Error 4/2/2012 11:35:39 PM SideBySide 59 None Error 4/2/2012 11:35:39 PM SideBySide 59 None Error 4/2/2012 11:35:39 PM SideBySide 59 None Error 4/2/2012 11:35:39 PM SideBySide 59 None Error 4/2/2012 11:35:39 PM SideBySide 59 None Error 4/2/2012 11:35:39 PM SideBySide 59 None Error 4/2/2012 11:35:39 PM SideBySide 59 None Error 4/2/2012 11:35:39 PM SideBySide 59 None Error 4/2/2012 11:35:39 PM SideBySide 59 None For those who are interested, here is my system configuration: ASRock M3A770DE AM3 AMD 770 ATX AMD Motherboard AMD Athlon II X3 455 Rana 3.3GHz Socket AM3 95W Triple-Core Desktop Processor ADX455WFGMBOX G.SKILL Value Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10600) Desktop Memory Model F3-10600CL9D-8GBNT Mushkin Enhanced Chronos Deluxe MKNSSDCR60GB-DX 2.5" 60GB SATA III Synchronous MLC Internal Solid State Drive (SSD) (Primary/Boot HD) Western Digital Caviar Blue RFHWD1600AAJS 160GB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive (Secondary HD) Sony Optiarc CD/DVD Burner Black SATA Model AD-7261S-0B LightScribe Support RAIDMAX RX-850AE 850W ATX12V v2.3 / EPS12V SLI Certified CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply ASUS HD7850-DC2-2GD5 Radeon HD 7850 2GB 256-bit GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video Card Asus ML228H 21.5" Full HD LED BackLight LED Monitor Slim Design (x3)

• Kickstart based installation of RHEL 6.4 from USB

  - by Peter

  I want to setup some brand new servers with RHEL 6.4. Servers do not have DVD, so, I have to use USB for the installation. I already have a custom ISO with a kickstart file that I use on servers with DVD flawlessly. I used iso2usb to move the ISO t? my USB. When I boot from the USB, the ks file is found, anaconda starts, but then stops with the following error: "The installation source given by device ['sda1'] could not be found. Please check your parameters and try again" Notes: The USB IS the sda. My custom ISO file is renamed to linux.iso from iso2usb and it is present in the root directory of the USB. Kickstart file has the following entry: harddrive --partition=sda1 --dir=/ Please help me to automate the installation with kickstart.

• Need Windows XP VGA driver for i3 Haswell

  - by AFH

  Background: I have recently upgraded my hardware because the previous Pentium system started failing to the point that it would not run long enough to boot. It was obviously a hardware fault, but I had no way of knowing whether it was in the motherboard, CPU or memory. Not all the components were now available, so I decided to replace all three. In order to get some benefit from the expenditure, I though I would put in faster components, and for future-proofing went for recently released ones: MSI Z87-G41-PCMate and Intel i3-4130 with 4400 HD graphics. The system performs excellently with Ubuntu 13.10, so I know there are no hardware problems, but I need to continue running XP because it runs several thousand pounds (UK) worth of software, which meets my needs more than adequately: in some cases there is no longer support for later Windows releases, and in most others an expensive and to me unnecessary upgrade is required. Problem: The motherboard specifications claim Windows XP support for the live driver update utility, which misled me into believing that XP drivers were available. Not true: Intel have apparently refused to provide XP drivers for Haswell chips. The update program runs on XP, but finds no suitable Intel drivers. The system is more or less running on the default fail-safe VGA driver, but DirectX will not load, which stops a number of my applications from running. I have been trawling the internet for a month now, but I have not found a graphics driver which will load successfully: all show "This device cannot start. (code 10)". I don't need HDMI support: my monitor is 1280x1024 and connected through the VGA port, so all I need is a driver which will handle this resolution well enough to support DirectX. Has anyone found a driver which will do this? Please don't reply with information found from internet searches, unless you have actually solved this problem: be assured that I have been all round the houses looking at solutions which others have reported as working, but none of them does for me. Incidentally, I did find an Intel HD sound driver which XP accepts (winxp_145111.exe from Intel), though without connecting to an HDMI port on a TV or sound system I have no idea if it works in practice. However, the graphics section of the same driver fails, like all the others I've tried.

• networking tunnel adapter connections?

  - by Karthik Balaguru

  I understand that Tunnel Adapter LAN is for encapsulating IPv6 packets with an IPv4 header so that they can be sent across an IPv4 network. Few queries popped up in my mind based on this :- If i do 'ipconfig', Apart from ethernet adapter LAN details, I get a series of statments as below - Tunnel adapter Local Area Connection* 6 Tunnel adapter Local Area Connection* 7 Tunnel adapter Local Area Connection* 12 Tunnel adapter Local Area Connection* 13 Tunnel adapter Local Area Connection* 14 Tunnel adapter Local Area Connection* 15 Tunnel adapter Local Area Connection* 16 Except for the *16, all the other Tunnel Adapter Local Area Connections show Media Disconnected. Why is the numbering for the Tunnel adapter LAN not sequential? It is like 6, 7, 12, 13, 14, 15, 16. A strange numbering scheme! I tried to figure it out by thinking of some arithmetic series. But, it does not seem to fit in. There is a huge gap between 7 and 12. Any ideas? What is the need for so many Tunnel Adapter LAN connections? Can you tell me a scenario that requires all of those ? I did ipconfig /all to get more information. From the listing, I understand that: 16, 15, 14, 12 are Microsoft 6to4 Adapters 13, 6 are isatap Adapters 7 is Teredo Tunneling Pseudo-interface I understand that the above are for automatic tunneling so that the tunnel endpoints are determined automatically by the routing infrastructure. 6to4 is recommended by RFC3056 for automatic tunneling that uses protocol 41 for encapsulation. It is typically used when an end-user wants to connect to the IPv6 Internet using their existing IPv4 connection. Teredo is an automatic tunneling technique that uses UDP encapsulation across multiple NATs. That is, It is to grant IPv6 connectivity to nodes that are located behind IPv6-unaware NAT devices ISATAP treats the IPv4 network as a virtual IPv6 local link, with mappings from each IPv4 address to a link-local IPv6 address. That is to transmit IPv6 packets between dual-stack nodes on top of an IPv4 network. That is, to put in simple words, ISATAP is an intra-site mechanism, while the 6to4 and Teredo are for inter-site tunnelling mechanisms. It seems that Teredo should alone enabled by default in Vista, But my system does not show it to be enabled by default. Interestingly, it shows a 6to4 tunnel adapter (Tunnel adapter LAN connection 16) to be enabled by default? Any specific reasons for it? If i do ipconfig /all, why is only one Teredo present while four 6to4 are present ? I searched the internet for answers to the above queries, but I am unable to find clear answers.

• DVD Drive Failing on Windows 7

  - by Seth Spearman

  I have x64 Windows 7 running on an ASUS M50VM. The DVD drive works completely unreliably if not at all. But the story is not that simple so bear with me...here are the gory details. When I first got the machine it came with Windows XP and I upgraded it to Windows Vista X64 and the DVD worked fine. When Windows 7 RC2 came out I tried it on a Virtual Machine and I liked it so much that I upgraded the machine to Win7 RC1. The DVD worked fine. Of course, RC1 was going to start spontaneously rebooting, so when Windows 7 was released I DID A CLEAN INSTALL of Windows 7. Just to clarify...by clean install I mean I did a FORMAT of the HARD DRIVE and INSTALLED it from scratch. EVER since then the DVD mostly doesn't work. I can sometime read from disk but that will often hang. (Please see my description below of HANG for details.) CD or DVD writes ALWAYS fail with a HANG (I have done a successful write only one time.) Here is what I mean by HANG... *Explorer Window is unresponsive. *Any software accessing the DVD drive is unresponsive. *The DVD tray will not eject. *Using a paper clip will eject but the disk is usually spinning real hard. *Attempting to shut down windows will fail. I have waited as long as ten minutes but the whole OS seems to hang. I do a hard shutdown. *Sometimes accessing the DVD (when it does not cause a HANG) will still fail and the device will actually seem to disappear from the system until I reboot. A couple of other things. It is NOT a hardware failure. It is the Windows OS. I know this because I swapped out my DVD drive with a friend with the same model...his machine is fine (he is still running Vista X64) and my machine still fails. For what it is worth. I swapped out my primary disk with the INTEL 160GB SSD. EDIT Here is what System Information shows about my DVD drive Drive D: Description CD-ROM Drive Media Loaded No Media Type DVD Writer Name HL-DT-ST DVDRAM GSA-T50N ATA Device Manufacturer (Standard CD-ROM drives) Status OK Transfer Rate -1.00 kbytes/sec SCSI Target ID 0 PNP Device ID IDE\CDROMHL-DT-ST_DVDRAM_GSA-T50N________________RR04____\5&2B5B7F1D&0&1.0.0 Driver c:\windows\system32\drivers\cdrom.sys (6.1.7600.16385, 144.00 KB (147,456 bytes), 7/13/2009 7:19 PM) Any ideas?

• Upgrading TFS 2005 to TFS 2010 fails at "Executing servicing step Upgrade Version Control Identities"

  - by nadeemmar

  Hi all, I have been trying to upgrade our TFS 2005 to TFS 2010 but with no luck so far. I went through the TFS Installation guide and many upgrade guides but with no luck in overcoming the issue I am facing which seems to be unique and different to other described issues. In our company, we have a domain forest with several domains. Lets say domain A, B, and C. TFS is in domain A and has users from all these three domains. All domains have trust reltionships between them. However, domain C was deleted several months ago. In the upgrade process, whenever I reach the collection upgrade step, the following error is raised: [Info @09:57:50.997] [2010-12-29 09:55:47Z][Informational] Step Data: ExtensionType = Microsoft.TeamFoundation.VersionControl.Server.PlugIns.WorkspaceSecurityNamespaceExtension [Info @09:57:50.997] [2010-12-29 09:55:47Z] Servicing step Create VersionControl Security Namespaces passed.

With a bit of googling, I figured out that TFSConfig Identities command can be used to remap users from one domain to the other. I went ahead and created local users that matches the users we have from domain C and ran the TFSConfig Identities /Change command and it executed successfully. However, I still get the same error. I am stuck and can't figure out how to move forward :( I need your expertise, has anyone faced this issue before? Do I need to change these identities on TFS 2005 before I commence the upgrade? I forgot to mention, I am following the upgrade with a move approach. I created a virtual machine for testing the upgrade. Installed SQL server 2008, restored the TFS databases and installed TFS 2010 and ran the upgrade wizard. Regards, Nadeem

• What the hell was THAT?!?

  - by Massimo

  My system is Windows XP SP3, updated with the latest patches. The PC is connected to a Cisco 877 ADSL router, which does NAT from the internal network to its single static public IP address. There are no forwarded ports, and the router's management console can only be accessed from the inside. I was doing two things: working on a remote office machine via VPN and browsing some web pages on the Cisco web site. The remote network is absolutely safe (it's a lab network, four virtual servers, no publicly accessible services and no users at all; also, none of what I'm going to describe ever happened there). The Cisco web site... well, I suppose is quite safe, too. Suddenly, something happened. Strange popups appears anywhere; programs claiming they're "antimalware", "antispyware" et so on begins autoinstalling; fake Windows Update and Security Center icons pop up in the system tray. svchost.exe began crashing repeatedly. Then, finally, after some minutes of this... BSOD. And, upon rebooting, BSOD again. Even in safe mode. Ok, that was obviously some virus/trojan/whatever. I had to install a new copy of Windows on another partition to clean things up. I found strange executables, services and DLLs almost anywhere. Amongst the other things, user32.dll and ndis.sys had been replaced. A fake software called "Antimalware Doctor" had been installed. There were services with completely random names or even GUIDs (!), and also ones called "IpSect" and "Darkness". There were executable files without an .exe extension. There were even two boot-class drivers, which I'm quite sure are the ones that finally caused the system to crash. A true massacre. Ok, now the questions: What the hell was that?!? It was something more than a simple virus! How did it manage to attack my computer, as I am behind a firewall and was not doing anything even only potentially harmful on the web at the time?

• Apache + PHP in paths with accented letters

  - by Álvaro G. Vicario

  I'm not able to run a PHP enabled web site under Apache on Windows XP if the path to DOCUMENT_ROOT contains accented letters. I'm not referring to the script file names themselves but to any folder in the path components. I have this virtual host definition: <VirtualHost *:80> ServerName foo.local DocumentRoot "E:/gonzález/sites/foo" ErrorLog logs/foo.local-error.log CustomLog logs/foo.local-access.log combined <Directory "E:/gonzález/sites/foo"> AllowOverride All Options Indexes FollowSymLinks Order allow,deny Allow from all </Directory> </VirtualHost> If I save the file in ANSI I get a syntax error: DocumentRoot must be a directory If I save the file in Unicode I get another syntax error: Invalid command '\xff\xfe#', perhaps misspelled or defined by a module not included in the server configuration (looks like it's complaining about the BOM) If I save the file in BOM-less UTF-8 Apache works fine and it serves static files with no apparent issue... ... however, PHP complaints when loading any *.php file (even an empty one): Warning: Unknown: failed to open stream: No such file or directory in Unknown on line 0 Fatal error: Unknown: Failed opening required 'E:/gonzález/sites/foo/vacio.php' (include_path='.;C:\Archivos de programa\PHP\pear') in Unknown on line 0 I decided to try the 8+3 short name of the directory (just a test, I don't want to use such a workaround): <VirtualHost *:80> ServerName foo.local DocumentRoot "E:/GONZLE~1/sites/foo" ErrorLog logs/foo.local-error.log CustomLog logs/foo.local-access.log combined <Directory "E:/GONZLE~1/sites/foo"> AllowOverride All Options Indexes FollowSymLinks Order allow,deny Allow from all </Directory> </VirtualHost> But I get the same behaviour: Warning: Unknown: failed to open stream: No such file or directory in Unknown on line 0 Fatal error: Unknown: Failed opening required 'E:/gonzález/sites/foo/vacio.php' (include_path='.;C:\Archivos de programa\PHP\pear') in Unknown on line 0 While there're obvious workarounds (use plain ASCII in all directory names or create NTFS junctions to hide actual names) I can't believe that this cannot be done. Do you have more information about the subject? My specs include 32 bit Windows XP Professional SP3, Apache/2.2.13 and PHP/5.2.11 running as Apache module (but I've noticed the same issue in another box with Windows Vista and PHP/5.3.1).

• keyboard mappings are totally screwed after updating to kde4

  - by zeonglow

  I recently upgraded from KDE 3.5 to KDE 4, and I have been having weird issues with my keyboard. In one of the virtual consoles e.g. when I press ctrl + alt 1 , I can type perfectly, but in KDE, several of the number keys don't work, the left and right arrows don't work either. When I press the right arrow key in xev I get this: KeyRelease event, serial 34, synthetic NO, window 0x3600001, root 0x6f, subw 0x0, time 903459, (111,55), root:(115,836), state 0x10, keycode 114 (keysym 0x1008ff11, XF86AudioLowerVolume), same_screen YES, XLookupString gives 0 bytes: XFilterEvent returns: False When I press the '3' key it toggles my Bookmarks toolbar in Firefox, in xev I get this: KeyPress event, serial 34, synthetic NO, window 0x3600001, root 0x6f, subw 0x0, time 999968, (94,115), root:(98,896), state 0x10, keycode 12 (keysym 0x1008ff30, XF86Favorites), same_screen YES, XLookupString gives 0 bytes: XmbLookupString gives 0 bytes: XFilterEvent returns: False KeyRelease event, serial 34, synthetic NO, window 0x3600001, root 0x6f, subw 0x0, time 1000032, (94,115), root:(98,896), state 0x10, keycode 12 (keysym 0x1008ff30, XF86Favorites), same_screen YES, XLookupString gives 0 bytes: XFilterEvent returns: False As this is deeper down, changing the type of keyboard in the KDE meun's has no effect. I'm slowly beginning to wade through the mountains of documentation about the X keyboard model, but there has to be a better way. Does anyone no what it is? Edit: 1234567890 ! after deleting the entire .kde folder. but only until I change the Keyboard settings from the "system settings" applet, then its hosed full time. Regardless of what I set the settings too. (restore to default settings doesn't) 2nd Edit: I'm using Gentoo AMD64, I was upgrading from KDE 3.5 KDE 4.2. I think I had manual settings before, although I didn't change anything. I was originally running KDE without HAL until that stop working a year or so ago. The only customisation I made was to set the multimedia keys to control Amarok. 3rd Edit $ grep xkb /var/log/Xorg.0.log (**) Option "xkb_rules" "evdev" (**) Option "xkb_model" "evdev" (**) Option "xkb_layout" "us" (**) Option "xkb_rules" "evdev" (**) Option "xkb_model" "evdev" (**) Option "xkb_layout" "us" Xorg.0.log has this to say: (WW) AllowEmptyInput is on, devices using drivers 'kbd', 'mouse' or 'vmmouse' will be disabled.

• Secret, unlogged, transparent, case-sensitive proxy in IIS6?

  - by Ian Boyd

  Does IIS have a secret, unlogged, transparent, case-sensitive proxy built into it? A file exists on the web-server: GET http://www.stackoverflow.com/javascript/ModifyQuoteArea.js HTTP/1.1 Accept: text/html, application/xhtml+xml, */* Accept-Language: en-US User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0) Accept-Encoding: gzip, deflate Connection: Keep-Alive Host: www.stackoverflow.com HTTP/1.1 200 OK Connection: Keep-Alive Content-Length: 29246 Date: Mon, 07 Mar 2011 14:20:07 GMT Content-Type: application/x-javascript ETag: "5a0a6178edacb1:1c51" Server: Microsoft-IIS/6.0 Last-Modified: Fri, 02 Tue 2010 17:03:32 GMT Accept-Ranges: bytes X-Powered-By: ASP.NET ... Problem is that a changes made to the file will not get served, the old (i.e. February of last year) version keeps getting served: HTTP/1.1 200 OK Connection: Keep-Alive Content-Length: 29246 Date: Mon, 07 Mar 2011 14:23:07 GMT Content-Type: application/x-javascript ETag: "5a0a6178edacb1:1c51" Server: Microsoft-IIS/6.0 Last-Modified: Fri, 02 Tue 2010 17:03:32 GMT Accept-Ranges: bytes X-Powered-By: ASP.NET ... The same old file gets served, even though we've: renamed the file deleted the file restarted IIS The request for this file does not appear in the IIS logs (e.g. C:\WINNT\System32\LogFiles\W3SVC7\) And this only happens from the outside (i.e. the internet). If you issue the request locally on the server, then you will: - get the current file (file there) - 404 (file renamed) - 404 (file deleted) But if i change the case of the requested resource, i.e.: GET http://www.stackoverflow.com/javascript/MoDiFyQuOtEArEa.js HTTP/1.1 Accept: text/html, application/xhtml+xml, */* Accept-Language: en-US User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0) Accept-Encoding: gzip, deflate Connection: Keep-Alive Host: www.stackoverflow.com Note: MoDiFyQuOtEArEa.js verses ModifyQuoteArea.js Then i do get the proper file (or get the 404 as i expect if the file is renamed or deleted). But any subsequent changes to the file will not show up until i change the case of the file i'm asking for. Checking the IIS logs all indicate that the (internet) requests are all coming the correct client on the internet (i.e. not from some intermediate proxy). Since the file doesn't exist on the hard drive anymore, i conclude that there is a proxy. The requests serviced from this proxy are not logged in the IIS logs. The requests for new files are logged, and from the client IP, not a proxy IP. The proxy is case sensitivie. This does not sound like something Microsoft, or IIS, would do: - a transparent proxy - case-sensitivie - unlogged - surviving restarts of IIS - surviving in a cache for hours i can't believe that our customer's IIS is doing these things. i'm assuming there is some other transparent proxy in front of IIS. Or, does IIS have a transparent, unlogged, case-sensitive, memory based, proxy, that caches content for at least 7 hours? (Come Monday morning, IIS is serving the correct file, unlogged).

• Web Site Serving, Cloud-Computing, oh, my

  - by Frank

  I'm planning a software based service. To give it a bit of context (type of traffic), assume it similar to facebook in nature (with a little GitHub thrown in). I've been trying to understand my different hosting options. I've been using a shared host with GoDaddy for years just fine. I currently host a Wordpress web site there and I've not had any problems. Quite frankly, they've taken good care of me. However, the nature of a shared hosting environment is limited in nature. For example, I can't do anything but host a web site there. For example, I can not run a Mercurial server. Last time I attempted to build a web application with the intention of eventually launching it via GoDaddy, I ran in to all sorts of troubles because it was shared-hosted. Assembly issues, etc. At the time, the cost and time sank my project. (The lack of direct access was also frustrating.) (to be fair to godaddy, this was over 3 years ago) I've been looking at Rackspace or Amazon as a possible cloud solution but it seems to be just processing power and bandwidth (and an OS). From what I understand, I'd need to get Apache and MySQL Working on my own. The way cloud hosting is priced, however, seems appealing. I figure my final option might be to use a virtual private host. I think this would be more flexible than a shared-host site but less scalable than a cloud based server. So, I guess my question is what is an appropriate solution for someone who intends to build a web application service? I figure that I need to establish a hosting environment now rather than later so I can plan to effectively use the environment. I'd prefer to be fairly economical to start out with. I really can't afford to pay $999 (or even $99) while I build up the site and get the core functionality online but at the same time, I'd like to have the selected environment grow as needed. Thank you.

• DVD Drive Failing on Windows 7

  - by Seth Spearman

  Hello, I have x64 Windows 7 running on an ASUS M50VM. The DVD drive works completely unreliably if not at all. But the story is not that simple so bear with me...here are the gory details. When I first got the machine it came with Windows XP and I upgraded it to Windows Vista X64 and the DVD worked fine. When Windows 7 RC2 came out I tried it on a Virtual Machine and I liked it so much that I upgraded the machine to Win7 RC1. The DVD worked fine. Of course, RC1 was going to start spontaneously rebooting, so when Windows 7 was released I DID A CLEAN INSTALL of Windows 7. Just to clarify...by clean install I mean I did a FORMAT of the HARD DRIVE and INSTALLED it from scratch. EVER since then the DVD mostly doesn't work. I can sometime read from disk but that will often hang. (Please see my description below of HANG for details.) CD or DVD writes ALWAYS fail with a HANG (I have done a successful write only one time.) Here is what I mean by HANG... *Explorer Window is unresponsive. *Any software accessing the DVD drive is unresponsive. *The DVD tray will not eject. *Using a paper clip will eject but the disk is usually spinning real hard. *Attempting to shut down windows will fail. I have waited as long as ten minutes but the whole OS seems to hang. I do a hard shutdown. *Sometimes accessing the DVD (when it does not cause a HANG) will still fail and the device will actually seem to disappear from the system until I reboot. A couple of other things. It is NOT a hardware failure. It is the Windows OS. I know this because I swapped out my DVD drive with a friend with the same model...his machine is fine (he is still running Vista X64) and my machine still fails. For what it is worth. I swapped out my primary disk with the INTEL 160GB SSD. EDIT Here is what System Information shows about my DVD drive Drive D: Description CD-ROM Drive Media Loaded No Media Type DVD Writer Name HL-DT-ST DVDRAM GSA-T50N ATA Device Manufacturer (Standard CD-ROM drives) Status OK Transfer Rate -1.00 kbytes/sec SCSI Target ID 0 PNP Device ID IDE\CDROMHL-DT-ST_DVDRAM_GSA-T50N________________RR04____\5&2B5B7F1D&0&1.0.0 Driver c:\windows\system32\drivers\cdrom.sys (6.1.7600.16385, 144.00 KB (147,456 bytes), 7/13/2009 7:19 PM) Any ideas? HELP! Seth B Spearman

• Add Mirror for volumes other than the last one in Windows 7 (disk "not up-to-date")

  - by rakslice

  I'm using Windows 7 x64 Ultimate. I have an existing 4TB disk with 3 NTFS volumes, a new 3TB blank disk, and I'm trying to mirror the volumes onto the new disk. My Windows install is on an SSD which is Disk 0. The 4TB disk with volumes is Disk 1, and the new blank disk is Disk 2. I can add a mirror successfully for the last volume, but when I try to add a mirror for the first volume I immediately get errors (see below). Is there something I special I need to do to add a mirror for a volume other than the last one? More info: I opened Disk Management, right-clicked on the first volume on the existing disk, went to Add Mirror, and selected the new disk. The first time I did this I was prompted to convert the new disk to a Dynamic Disk, which I approved. Subsequently I got a message: The operation failed to complete because the Disk Management console view is not up-to-date. Refresh the view by using the refresh task. If the problem persists close the Disk Management console, then restart Disk Management or restart the computer. I've refreshed disk management, restarted the computer, and converted the new disk to basic and back to dynamic, but I still get that error message. Looking around for suggestions of a workaround, I saw a suggestion to use the diskpart command line tool. Running diskpart from the Start Menu as Administrator, I did select volume 2 (the first volume I want to mirror) and then add disk 2 (the new disk), and received a somewhat similar error: Virtual Disk Service error: The disk's extent information is corrupted. DiskPart has referenced an object which is not up-to-date. Refresh the object by using the RESCAN command. If the problem persists exit DiskPart, then restart DiskPart or restart the computer. A rescan appears to be successful: DISKPART> select disk 2 Disk 2 is now the selected disk. DISKPART> rescan Please wait while DiskPart scans your configuration... DiskPart has finished scanning your configuration. but attempting to add the mirror again resulted in the same error. The only similar report I found online was this: http://www.sevenforums.com/hardware-devices/335780-unable-mirror-all-but-last-partition-drive.html Based on that I attempted to mirror the last volume on the disk to the new disk using diskpart, and that started successfully -- it is currently resynchronizing. More Background: In the course of dealing with a failing 3TB hard drive, I bought a replacement 4TB drive and installed it, then copied the partitions from the failing drive to it using Minitool Partition Wizard Home, and then removed the failing drive and was up and running again normally. Now I've received a warranty replacement for the failing drive, and installed it, and now I'm attempting to mirror my partitions to it.
