• How configure 2 Lan cards in Windows 7/8 pc one to connect to Internet and other to Local Network

  - by Maharshi Raval

      I am about to install a dedicated VOIP server in our office. It is a 3CX pbx system on Windows 7/8 machine. The environment currently is a Windows SBS 2011 with 8 client machines. I want to use a dedicated broadband connection for the PBX (3CX) box, but the box also needs to be accessible in the local network as we will be using IP Phones and software IP phones. How configure two network cards on PBX box, so that one will be always used to connect to our SIP host over the Internet and the other will be connected to local network accessible from other client pc to connect to the pbx system. It must be noted that currently the Windows SBS 2011 acts as the Primary Domain Controller and gateway for all the client machines.     I cannot use a load balancer as it will conflict and cause issues within the current setup of our SBS2011 as it is also our Exchange Server. Any input is much appreciated. thanks in advance

• Caching/preloading files on Linux into RAM

  - by Andrioid

  I have a rather old server that has 4GB of RAM and it is pretty much serving the same files all day, but it is doing so from the hard drive while 3GBs of RAM are "free". Anyone who has ever tried running a ram-drive can witness that It's awesome in terms of speed. The memory usage of this system is usually never higher than 1GB/4GB so I want to know if there is a way to use that extra memory for something good. Is it possible to tell the filesystem to always serve certain files out of RAM? Are there any other methods I can use to improve file reading capabilities by use of RAM? More specifically, I am not looking for a 'hack' here. I want file system calls to serve the files from RAM without needing to create a ram-drive and copy the files there manually. Or at least a script that does this for me. Possible applications here are: Web servers with static files that get read alot Application servers with large libraries Desktop computers with too much RAM Any ideas? Edit: Found this very informative: The Linux Page Cache and pdflush As Zan pointed out, the memory isn't actually free. What I mean is that it's not being used by applications and I want to control what should be cached in memory.

• Linux usd disk just create sg device

  - by MTilsted

  I have a Corsair R60 ssd disk which is a disk with both sata and usb connectors. But the usb thing seems to be a bit non-standard, or maybe its just my fedora linux. When I insert the disk using a usb cabel to a running Fedora 14 linux system, a device called /dev/sg3 is added but that is all. No new /dev/sd* device is created so I can't mount the disk. If I look at cat /proc/scsi/sg/device_strs I get ATA Hitachi HTS54321 FB2O HL-DT-ST DVDRAM GSA-T50N RP05 Seagate Desktop 0130 Corsair CSSD-R60GB2 So the disk is there. (The last entry) but my linux will for some reason not see it as a usb hard disk. When I insert other usb disks they work fine. It is only this specific disk which causes problems. I have tried on 3 different computers with the same result. A hint to the problem may be that if I add the disk to a windows system(With usb) the disk is called "A fixed disk" and not a portable disk as expected. The disk works fine with linux If i connect it with the sata cabel, but I would really like to have it working with usb too. (To mount it on computers without sata).

• Converting a Windows 2003 server

  - by Jim Bass

  We have a legacy database system based upon MS SQL running on Windows Server 2003. The client software will only run on Windows XP. We have recently had success converting a client into a virtual machine and running it under Fusion on Mac minis. So far, it is working incredibly well. So well, in fact, that we are now considering trying to convert the server to a virtual machine. This raises several questions, though: 1. The server uses a raid array. Does the VM virtualize the raid array? I only ask because in my experience Windows products don't like it when you change core hardware. 2. Is there any reason why running SQL server on a virtual machine won't work? It will be up 24/7. 3. Is there a different converter for servers? 4. Will I have to track down the licensing for MS SQL and Server 2003 or will they come across ok? 5. The company that designed the software is no longer in business. There is some fear that the software is somehow tied to the hardware configuration. We bought the hardware, but their engineers came out and configured the system. Will the virtual machine be able to spoof particular chip sets? Thanks! Jim Bass

• Remove directory from URL IIS 7.5

  - by xalx

  I've tried to find a solution to this and found some guides out there but none seem to work. I have the following URL - http://www.mysite.com/aboutus.html However there are some other sites which link to my old hosted site and point to http://www.mysite.com/nw/aboutus.html. My issue here is trying to remove the 'nw' directory from the URL's. I have setup the following URL Rewrite in IIS but it does not seem to do anything, <?xml version="1.0" encoding="UTF-8"?> <configuration> <system.webServer> <rewrite> <rules> <rule name="Redirect all to root folder" enabled="true" stopProcessing="true"> <match url="^nw$|^/nw/(.*)$" /> <conditions> </conditions> <action type="Redirect" url="nw/{R:1}" /> </rule> <rule name="RewriteToFile"> <match url="^(?!nw/)(.*)" /> <conditions> <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" /> <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" /> </conditions> <action type="Rewrite" url="/{R:1}" /> </rule> </rules> </rewrite> </system.webServer> </configuration> Any insight would be appreciated.

• Installing Ubuntu guest crashes Hyper-V host

  - by Grant

  I have a weird problem that I don't even know where to begin diagnosing. Trying to install Ubuntu to a VM locks up the host system! My setup is: Dell R715 server, dual 16 core AMD opteron processors, 96GB RAM Dell MD3600f SAN Server 2008 R2 Datacenter System Center VMM 2012 There are 5 windows virtual machines running that have had no problems. This is the first linux VM I've tried to create. I setup a VM through virtual machine manager, set the CD drive to a Ubuntu 12.04 server x64 iso, and started it up. It boots up the normal ubuntu install menu, but the second I hit enter on "Install Ubuntu Server", I get disconnected. The HOST machine stops responding to pings. So do all virtual machines on it. It locks up entirely - keyboard on the host won't work, mouse won't move, numlock light won't change. There's no blue screen - the host is sitting at the login screen completely unresponsive. I can't find any relevant logs in event viewer after rebooting. What could cause the host machine to freeze like that? It's not a one time occurrence - it happens every time at the exact same point. Thank god this server isn't in production yet!

• Moving hidden files/folders with the command-line or batch-file

  - by Synetech

  Question Does anyone know of a way to move files and folders that have the hidden, system, or read-only attribute set from the command-line or a batch file? (No, stripping the attributes first is not an option since there is no practical way to know which attributes were set in order to re-set them after the move.) (Failed) Attempts Using the basic move command does not work with items with the hidden or system attribute set and for some reason, it does not have switches to specify attributes like the dir and del commands do. I tried using a utility I wrote that uses the shell’s file operation function, but that requires using start /w to prevent the batch file from running on ahead, and it complains about long-filename support for some reason. I tried using robocopy, but it first copies the files and then deletes the originals instead of simply moving the source (which results in a frustrating delay, even with the excessive output redirected to nul). (Surprisingly it seems that few people have ever needed to move hidden files from the command-line. All I could find was this one person who abandoned the attempt.)

• Windows 7 Startup fails after installation

  - by Nadav S.

  I have installed Windows 7 Ultimate a week ago. Yesterday I've noticed that the SP1 update is available. After installation of SP1 the computer failed to startup, and had shown a black screen. I couldn't even go to safe mode and F8 didn't help. After some fixing attempts including system restore, startup repair, bootmgr & BCD rebuilding from CMD, I have decided to reinstall Windows (after all, it's only a week old) After the successful installation, I have decided to first install all available updates before I continue. So after the updates download & installation, the computer rebooted. And now I didn't see the black screen again - but in the "Starting Windows..." screen the logo didn't appear and the system didn't startup. Here I could go to safe mode selection window, but it didn't work either ("Loading Windows Files" but nothing). I've also tried: I thought that the CD was corrupted, so I've used a fresh new disk of Windows, tried x86 & x64 versions, the same symptoms, no change. Resetted the BIOS to default, no change. Memory diagnostic HDD diagnostic Restarted Windows WITHOUT INSTALLING UPDATES, but it had the same symptom, so maybe Windows Update is not the case?! I've tried installing it so many times - that I am simply stuck - I can't "reinstall Windows, because it is corrupted...". Maybe the HDD is corrupted? I've also checked it and didn't find a problem.

• How can I change the binding order of network adapters in Windows 7?

  - by Chris Farmer

  The end goal here is that I am trying to install an Oracle 10g server on my Windows 7 x64 dev box. I use DHCP, and the Oracle installer is throwing up this warning: Checking Network Configuration requirements ... Check complete. The overall result of this check is: Failed <<<< Problem: The install has detected that the primary IP address of the system is DHCP-assigned. Recommendation: Oracle supports installations on systems with DHCP-assigned IP addresses; However, before you can do this, you must configure the Microsoft LoopBack Adapter to be the primary network adapter on the system. See the Installation Guide for more details on installing the software on systems configured with DHCP. I have installed the loopback adapter, but I am not sure how to make it the primary network adapter. I see this Microsoft KB article on the subject but it's Windows XP-oriented, and I can't seem to find a comparable one for Windows 7. Some of the options it talks about don't seem to be present in the views of the adapters that I see. So, how can I make the loopback adapter become the primary adapter?

• certutil -ping fails with 30 seconds timeout - what to do?

  - by mark

  Dear ladies and sirs. The certificate store on my Win7 box is constantly hanging. Observe: C:\1.cmd C:\certutil -? | findstr /i ping -ping -- Ping Active Directory Certificate Services Request interface -pingadmin -- Ping Active Directory Certificate Services Admin interface C:\set PROMPT=$P($t)$G C:\(13:04:28.57)certutil -ping CertUtil: -ping command FAILED: 0x80070002 (WIN32: 2) CertUtil: The system cannot find the file specified. C:\(13:04:58.68)certutil -pingadmin CertUtil: -pingadmin command FAILED: 0x80070002 (WIN32: 2) CertUtil: The system cannot find the file specified. C:\(13:05:28.79)set PROMPT=$P$G C:\ Explanations: The first command shows you that there are –ping and –pingadmin parameters to certutil Trying any ping parameter fails with 30 seconds timeout (the current time is seen in the prompt) This is a serious problem. It screws all the secure communication in my app. If anyone knows how this can be fixed - please share. Thanks. P.S. 1.cmd is simply a batch of these commands: certutil -? | findstr /i ping set PROMPT=$P($t)$G certutil -ping certutil -pingadmin set PROMPT=$P$G

• How to migrate Outlook Express mail rules?

  - by ronwest

  I have a home computer that only had a 15Gb C: drive, and ran out of space with all the Microsoft Updates, etc, that keep coming down. So I fitted a 160Gb drive as a C: drive and altered the drive jumpers to make the old C: drive into a slave D: drive, to save migrating documents, etc. I've installed a clean copy of Windows XP SP3 and reassigned the new Outlook Express' mailstore path to point to the old mailstore folder that now has a D: drive letter - and it all works OK. However, my extensive list of mail rules have not been transferred to the new OE and I have not been able to identify how they are stored. To find it I added a new rule to the new OE, exited OE, then searched on the whole computer (including hidden/system files) for files altered around the time I added the rule. I hoped I could just overwrite a new empty file with an old one. But the only files that seem to be changed are Windows system-level files and some bits and pieces in the Windows\PreFetch sub-folder. None of them can be opened as XP has them locked, and none of them have names that are anything to do with email or rules. Does anyone know of any way of migrating OE rules, or do I have to re-enter them by hand? Thanks!

• Replace Linux Boot-Drive | ext3 to btrfs

  - by bardiir

  I've got a headless server running Debian Linux currently. Linux vault 3.2.0-3-686-pae #1 SMP Mon Jul 23 03:50:34 UTC 2012 i686 GNU/Linux The root filesystem is located on an ext3 partition on the main harddrive. My data is located on multiple harddrives that are bundled to a storage pool running with btrfs. UUID=072a7fce-bfea-46fa-923f-4fb0827ae428 / ext3 errors=remount-ro 0 1 UUID=b50965f1-a2e1-443f-876f-578b5f93cbf1 none swap sw 0 0 UUID=881e3ad9-31c4-4296-ae60-eae6c98ea45f none swap sw 0 0 UUID=30d8ae34-e2f0-44b4-bbcc-22d761a128f6 /data btrfs defaults,compress,autodefrag 0 0 What I'd like to do is to place / into the btrfs pool too. The ideal solution would provide the flexibility to boot from any disk in the system alike, so if the main drive fails I'd just need to swap another one into the main slot and it would be bootable like the main one. My main problem is, everything I do needs to result in a bootable system that is open to ssh logins via network as this server is 100% headless so there is no possibility to boot it from a live cd or anything like that. So I'd like to be extra sure everything works out fine :) How would I best go about this? Can anybody hint me to guides or whip something up for these tasks? Anything I forgot to think about? Copy root-data into btrfs pool, adjust mountpoints,... Adjust GRUB to boot from btrfs pool UUID or the local device where GRUB is installed Sync GRUB to all harddrives so every drive is equally bootable (is this even possible without destroying the btrfs partitions on the drives or would I need to disconnect the drives, install grub on them and then connect them back with a slightly smaller partition?)

• How can I setup a Proxy I can sniff traffic from using an ESX vswitch in promiscuous mode?

  - by sandroid

  I have a pretty specific requirement, detailed below. Here's what I'm not looking for help for, to keep things tidy and on topic: How to configure a standard proxy Any ESX setup required to facilitate traffic sniffing How to sniff traffic Any changes in design (my scope limits me) I need to setup a test environment for a network-sniffing based HTTP app monitoring tool, and I need to troubleshoot a client issue but he only has a prod network, so making changes to the config on client's system "just to try" is costly. The goal here is to create a similar system in my lab, and hit the client's webapp and redirect my traffic - using a proxy - into the lab environment. The reason I want to use a proxy is so that only this specific traffic is redirected for all to see, and not all my web traffic (like my visits to serverfault :P). Everything will run inside an ESX 4.1 machine. In there, there is a traffic collection vswitch in promiscuous mode that is not on the local network for security reasons. The VM containing our listening agent is connected to this vswitch. On the same ESX host, I will setup a basic linux server and install a proxy (either apache + mod_proxy or squid, doesn't matter). I'm looking for ideas on how to deploy this for my needs so I can then figure out how to set it up accordingly. Some ideas I've had were to setup two proxies, and have them talk to eachother through this vswitch in promiscuous mode, but it seems like alot of work. Another idea is a dual-homed proxy, but I've never seen/done that before so I'm not sure how doable it is for what I'd like. I am OK with setting up a second vswitch in promiscuous mode to facilitate this if need be, but I cannot put the vswitch on the lan (which is used so my browser would communicate with the proxy) in promiscuous mode. Any ideas are welcome.

• All of the NTFS hard links damaged, where are hardlinks stored and how to recover them?

  - by String Xu

  This is Windows 7 x64 sp1 on a NTFS file system. All hardlinks within C:\Windows\System32 folder disappear, and the Windows can't boot, because even the osloader, C:\Windows\System32\boot\Winload.exe also disappeared. Nevertheless, the original files are still located in the corresponding C:\Windows\winsxs folders. After booting into the Recovery Environment, and copied one Winload.exe (x64) from other folder, Windows gave an error pointing out that "ntoskrnl.exe is corrupted or missing...its file digital signature cannot be verified" In trying to boot in Safe Mode, the message above was shown after a screen prompting "Loaded \Windows\system32\config\system" Because at this early booting stage, smss.exe was still not loaded, so there is not any dumping and logs. Based on my study, ntoskrnl.exe depends on the following files: C:\windows\system32\PSHED.DLL C:\Windows\System32\hal.dll C:\Windows\System32\kdcom.dll C:\Windows\System32\clfs.sys C:\Windows\System32\ci.dll All those files above are copied from their corresponding folders and verified their md5 with a well-operating Windows 7 x64 SP1. But the booting error is still the same: "ntoskrnl.exe is corrupted or missing..." Background: 1. Before the reboot, there was an windows update going on. Then something unknown happen, almost all processes were broken to run, including the windows task manager, taskmgr.exe. After mount the hard disk to other computer, it seems that all hardlinks within C:\Windows\System32 folder were gone. I tried several data recovery software, but they are not be able to find those disappeared NTFS hard links. So the question is: Where are information about those hard links stored? And how to recover them? Are they depend on some windows service or stored in the registry?

• kde dropping keyboard

  - by shabbychef

  I am having problems with KDE 'dropping' my keyboard. It happens periodically when using my gentoo box directly, but has become much worse when accessing via NX (from a Mac laptop). Some possibly irrelevant clues: it appears to happen more often when the system is under higher CPU load the mouse continues to work, but no windows will accept any kind of keyboard focus. kwin will not accept tabbing between windows. when working on the machine directly, I can ctrl-alt-F1 to get to a shell (obviously this does nothing over NX). so I think it is KDE and not xorg. am running kwin-4.3.5-r1, and KDE-4.3.5 generally. this problem definitely appeared after upgrading to kde-4.x, but I do not remember if it appeared in kde-4.2. sometimes the keyboard will reappear, but sometimes I have to kill my kde session. playing with accessibility options or window-focus-stealing options in system-settings under kde will often make the keyboard responsive again, only to drop it perhaps minutes later. I had read online this might be an evdev problem under X (again, I think this is KDE, not X, but will try anything). as a result, I have fiddled with my xorg.conf endlessly. I even deleted it entirely and let nvidia-xconfig have a stab at it, with no luck I am tearing my hair out over this. I have done emerge -e xorg-server and am right now doing emerge -e kwin, to rebuild all packages that might be relevant. no luck with the xorg-server rebuild. any help appreciated. thanks,

• VMWare web UI intermittent access on CentOS

  - by PeteWilliams

  I've got a CentOS 5.2 server that I'm trying to get set up as a development environment. As part of this, I planned to install VMWare Server 2 and set up several virtual development servers. I've got as far as installing VMWare Server 2 but access to the remote control panel is only working intermittently. If I access it through Firefox at https://127.0.0.1:8333/ui/# it usually says either: "Connection intterupted: connection was reset before the page loaded" Or "Firefox can't establish a connection to the server at 127.0.0.1" But every now and then it lets me in and I'll manage a few clicks in the web UI before it kicks me out with the following error: "The server could not complete a request (HTTP 0 ). The server encountered an unexpected condition that prevented it from fulfilling the request. If this problem persists, please contact your system administrator." I've done all the updates available in CentOS except one OpenOffice one that is causing a conflict, and I re-ran wmware-config.pl after updating the kernel. Though I went with all the defaults as I don't really know what I'm doing! I've since rebooted and nothing changed. I've also tried accessing the control panel remotely from another machine in the network and the results are the same. Does anyone have any ideas what might be causing this and how I can resolve it? I'm afraid I'm a developer playing at sys-admin, so I may be missing something obvious! Many thanks Pete Update I have now reinstalled both the operating system and VMWare and I'm still getting the same issue. I wonder if it's a result of the settings I'm putting in on the config.pl script..?

• Mac OS X in Virtualbox says "You need to restart your computer"

  - by humoeba

  I've been trying to figure out for the past week how to get Snow Leopard reliably running in a VM. Right now I am using VirtualBox, and it runs fine for a while, but every once in a while (happened 3 times in the last few hours) I get the "You need to restart your computer" message. Unfortunately, it hasn't even lasted long enough to finish installing the operating system yet. I first tried VMWare, which was a pain to set up. I got it running ok, operating system installed, with the guest tools. Every once in a while though, it just stops running. I click inside the VM, and there's no mouse. It doesn't respond to keyboard input either. I have to reset the VM to get a response. I'm wondering if this is the same error. This happens with both Workstation and Player. Here is the tutorial I used for VirtualBox: http://www.sysprobs.com/iboot-loader-virtualbox-install-snow-leopard Here's the tutorial I used for VMWare: http://bobhood.wordpress.com/2009/12/18/welcome-to-snow-leopard-mac-os-x-10-6-and-vmware-workstation-7/ I'm using an iso for Mac OS X 10.6.3. I have an HP Pavilion dm4 with an Intel Core i7 M640 running Windows 7; VT is turned on. Using VirtualBox 4.0.4 and VMWare Workstation 7.0.1 and VMWare Player 3.0.1 Does anyone know what might be causing this error or how I can fix it? Thanks.

• "What happens?" server performance monitor

  - by AlexAtNet

  Hello! After reviewing some thread about server monitoring software I end up with a simple question: Which of the server monitoring tools should I use for automatic detection of "abnormal" situations with recommendations on how to fix them? I look for software that checks the system performance after installation and calculate some average load values (memory, CPU, etc). And when something happens (CPU load is increased to 20%) then it tries to detect a reason for this. If it is apache, it should check for access logs. If mysql, it should check mysql logs and tell me what happens. It this is because some user decodes a lot of images, I'd like to know which command is executed, when and user name. The same for disk usage, memory, number of processes, threads and so on. Ideally, this software should periodically checks the system and report problems: errors in PHP error log, outdated packages, security vulnerabilities. In other word I'm looking a software that will keep my simple Debian/Apache/PHP/MySQL server without forcing me to monitor the charts every day. I hope that such program exists. Thanks, Alex

• Why does my microwave kill the Wi-Fi?

  - by Ohlin

  Every time I start the microwave in the kitchen, our home Wi-Fi stops working and all devices lose connection with our router! The kitchen and the Wi-Fi router are in opposite ends of the apartment but devices are being used a little here and there. We've been annoyed by the instability of the Wi-Fi for some time and it wasn't until recently we realized it was correlated to microwave usage. After some testing with having the microwave on and off we could narrow down the problem to only occurring when the router is in b/g/n mode and uses a set channel. If I change to b/g mode or set channel to auto then there is no problem any more...but still! The router is a Zyxel P-661HNU ("802.11n Wireless ADSL2+ 4-port Security Gateway" with latest firmware) and the microwave is made by Neff with an effect of 1000W (if this information might be useful to anyone). There is an "internet connection" light on the router and it doesn't go out when the interruption occurs so I think this is only an internal Wi-Fi issue. Now to my questions: What parts of the Wi-Fi can possibly be affected by the microwave usage? Frequency? Disturbances in the electrical system? How can setting Auto on channels make a difference? I thought the different channels were just some kind of separation system within the same frequency spectrum? Could this be a sign that the microwave is malfunctioning and slowly roasting us all at home? Is there any need to be worried? Since we were able to find router settings that cooperate well with our microwave's demand for attention, this question is mainly out of curiosity. But as most people out there...I just can't help the fact that I need to know how it's possible :-)

• Regarding partitions for dual-booting Ubuntu with pre-existing Windows 7

  I have zero actual experience with configuring disk partitions and the stuff I have read for the past few hours have been confusing me a bit, so please bear with me. First of all, I'd like to explain what I'm setting to achieve: Windows 7 with: C:\ Windows 7 (pre-existing installation) D:\ Data (Already exists and has files already) Ubuntu 11 - Does not exist yet, but I already have a LiveCD in hand. \root directory for Ubuntu \home on its own partition I plan \swap on its own partition with around 8GB Here is the current situation: I have a single 500 GB hard-disk with Windows 7 x64 installed, and the current partition schemes is as follows: System Reserved: 100 MB (Primary, Active) C: 100 GB - Where Windows 7 is installed (Primary) D: 365 GB - Where my files are located, LOTS of free space (Primary) Now, I would like to shrink my D: drive and create around 40 GB of unallocated disk space for the Ubuntu installation, but here what's confusing me a bit: I'm thinking I would create an extended partition and subdivide it into 3 logical partitions for the Ubuntu setup I had in mind. (If you think my setup is a bad idea, please let me know & why. I also hope you can suggest a better one...) I am aware that I can only have up to 4 primary partitions, or 3 primary partitions with 1 extended parition max. Now, does the System Recovery portion count as one primary partition? I'm really new to these things and it is totally unclear to me. In shrinking my D: drive using Windows 7's Disk Management tool, I would get an unallocated free space which I don't know how to make an extended partition from. It seems like I can only create a primary partition from it, not an extended one. How do I go about it? (I'd also like to note, if it is of any importance, that I am trying to avoid using the option to install Ubuntu alongside Windows, and much rather prefer using the custom install where I can specify which drives I wish to use and stuff. Somehow I feel its safer that way.)

• Windows 7 hangs with 100% disk activity but only when online

  - by jeremy

  I have the same problem as seemingly many other people here, and I think we might all be experiencing the same issue: a compatibility issue in Windows 7 between hard drive and network controller or drivers. I've tried firmware updates of my entire board, wiping my drive and reinstalling from scratch. And yet the problem persists, which suggests it is an operating system error, as the hard drive checks out 100% physically. Additionally, the only time it does not occur is when in safe mode WITHOUT networking. With networking, there are spikes in disc access every so often and a huge flow of processes accessing the disc simultaneously that literally "stick" the disc, and physically jolting my computer unsticks it. Again, this has been tested for hours in a professional service environment, and without network access on, things are fine. As soon as there's network access available, the disc access occasionally cranks up to 100% and sticks everything. I'm using Microsoft Security Essentials, but this also happened under Norton, then McAfee. Again, this happened again after a complete wipe, so the likelihood of malware causing it seems low. I don't visit unsecure sites anyway, as far as I know. This, to me, narrows it down to a Windows 7 process that is somehow repeatedly corrupted, perhaps a corrupt .dll or driver, causing a conflict at the operating system level and temporary hard drive failure. I would encourage anyone who knows more about this stuff (which is probably most people!) to take a shot at this one, and I would encourage anyone else with a sticking hard drive in windows 7 64-bit to check on whether it occurs during safe mode without networking.

• Protect all XML-RPC calls with HTTP basic auth but one

  - by bodom_lx

  I set up a Django project for smartphone serving XML-RPC methods over HTTPS and using basic auth. All XML-RPC methods require username and password. I would like to implement a XML-RPC method to provide registration to the system. Obviously, this method should not require username and password. The following is the Apache conf section responsible for basic auth: <Location /RPC2> AuthType Basic AuthName "Login Required" Require valid-user AuthBasicProvider wsgi WSGIAuthUserScript /path/to/auth.wsgi </Location> This is my auth.wsgi: import os import sys sys.stdout = sys.stderr sys.path.append('/path/to/project') os.environ['DJANGO_SETTINGS_MODULE'] = 'project.settings' from django.contrib.auth.models import User from django import db def check_password(environ, user, password): """ Authenticates apache/mod_wsgi against Django's auth database. """ db.reset_queries() kwargs = {'username': user, 'is_active': True} try: # checks that the username is valid try: user = User.objects.get(**kwargs) except User.DoesNotExist: return None # verifies that the password is valid for the user if user.check_password(password): return True else: return False finally: db.connection.close() There are two dirty ways to achieve my aim with current situation: Have a dummy username/password to be used when trying to register to the system Have a separate Django/XML-RPC application on another URL (ie: /register) that is not protected by basic auth Both of them are very ugly, as I would also like to define a standard protocol to be used for services like mine (it's an open Dynamic Ridesharing Architecture) Is there a way to unprotect a single XML-RPC call (ie. a defined POST request) even if all XML-RPC calls over /RPC2 are protected?

• Print from Linux to Windows networked printer

  - by wonkothenoob

  I want to print from a Debian (Lenny) workstation to a Windows networked printer. I'm not even sure what type of Windows network this is. Our tech-support is friendly but doesn't want to get involved with supporting Linux. I need to use it for a variety of reasons and am completely stumped because I know nothing about Windows networking. They gave me URI smb://msprint.ourorg.edu as the "address" of the printer and further confirmed that the domain is "OURORG" and the share is "PHYS-PRI". I've installed CUPS and made sure that it's running as a daemon, I've clicked on the system-config-printer[1] icon, selected the printer as a Windows printer shared via SAMBA and entered the above URI. Attempting to print a testpage just sees it sit in the queue. I attempted to see if I could access the share using two other methods. Method 1. First I tried the "smbclient" from the CLI: $ smbclient -L //msprint.ourorg.edu -U user23 timeout connecting to 192.168.44.3:445 timeout connecting to 192.168.44.3:139 Connection to msprint.ourorg.edu failed (Error NT_STATUS_ACCESS_DENIED) Method 2. I tried to use the GUI tool Smb4K. This shows me four other toplevel (I'm assuming they're domains?) groupings one of which is the one which our IT department supplied to me. Clicking them shows a bunch of other machines with (what I assume are NetBIOS names?) including my own. I see all sorts of other networked printers belonging to other departments but none within mine. Certainly not the PHYS-PRI one suggested to me by the IT folks. I realize that I'm probably using the wrong terminology for the windows network, but can anyone help me with this? What steps should I be taking in debugging this? Do I need to actually run my machine as a SAMBA server to authenticate to the printer or should I just be able to communicate using CUPS? It's a GUI to CUPS configuration http://cyberelk.net/tim/software/system-config-printer/
