• SBS 2003 boot stalls at acpitabl.dat

  - by John

  I have a SBS 2003 server running for 3 year without any problems, and few days ago it freezes during the boot. System is using two 500 Gb drives in RAID1 (Intel Matrix 7.5) After trying to load in safe mode, boot stops on acpitabl.dat. First idea was that there is a problem with RAID altough disk status was OK, and RAID status was Rebuild. I tried to boot with each drive, and one gives me the same problem, and the other drive is failing to load. Took both drives out, and checked it on a different machine. One drive is dead, other is without any problems. Returned the good drive back in SBS 2003 with changed status to Degraded, but the problem is still the same. I also have a clean SBS 2003 copy installed on this drive (previous installation), which loads smooth and quick. So, I believe the main problem is this installed version of SBS 2003. Did not make any hardware changes, did not make any updates (not sure about any automatic windows updates lately). Since there are tons posts about this problem, and no clear solution, I am trying to figure how to repair SBS 2003 installation, since there are some installed programs on this installation which I cannot re-install without additional issues.

• Home network with two isolated separate subnets, running on cablemodem/router and WRT-router.

  - by Johan Allgoth

  I have a new connection with a nice new router/cable-modem. I'd like to setup it up optimally and needs some pointers. I am a complete n00b when it comes to routing. I want to end up with two separate subnets, 10.1.2.0/24 and 192.168.1.0/24 each available on their own wireless channel/SSID. Both firewalled. I want my wired computers on the gigabit switch, optimally with public ips. I want to be able to reach 192.168.1.0/24 from 10.1.2.0/24, but not vice versa. Everyone should have internet access. Hardware and capabilities: Netgear CG3100. Handles cable connection. Gigabit switch. 802.11n. Can do DHCP, firewall, NAT etc. Can choose subnet. Can turn of NAT and if so hand out up to 4 public ips. Somewhat challenged when it comes to configuration. WRT-router. Runs DD/Open-WRT very stable. 100 Mbit switch. 802.11.g Can do DHCP, firewall, NAT etc. Can choose subnet. Highly configurable. I hope to be able to keep 10.1.2.0/24 on the CG3100, for speed reasons and 192.168.0.0/24 on the WRT-router for quota and user control reasons. On my 10.1.2.0/24 network I plan on running servers for various services. Should I turn of NAT on the WRT-router? Or on the cable modem? Activate what in that case? Is double NAT always f-ed up?

• SQL Server replication and load balance

  - by Ahmed Galal

  I'm running a web service that serves a mobile app on IIS 8 and SQL Server 2014, my service has a massive load and i'm trying to improve performance, most of the load is happening on SQL. i don't think i have a bottleneck, my processor and ram is up to the max and i think my code is not that bad, am already using memcached and other stuff to avoid hitting SQL too much. i know i can always upgrade the server hardware but i already have a spare server that i would like to use, so i was thinking to split the SQL load on the 2 servers. What i was thinking of is to setup replication on the other server and do some load balancing, but am not sure how to do the load balance. I know i can adjust my code to hit the other server for some queries but i was hoping to find a solution that avoid changing my code. So my question is, What are the ways of doing load balancing between 2 SQL servers ? I would appreciate suggestions or best practices or some directions. Thanks.

• Server freezes while installing Redhat Enterprise Linux Server 6

  - by eisaacson

  We've tried both the first options Install or upgrade an existing system Install system with basic video driver When trying option #1, it gets to a screen that has a solid cursor about halfway down, then freezes. When trying option #2, it freezes at the point where it says: Waiting for hardware to initialize... Of course, we bought the unsupported version and haven't found anything to help us so far. Here are the specs to the server in the original post: ASUS P8Z68-M Pro LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 Micro ATX Intel Motherboard with UEFI BIOS RAIDMAX Reiter ATX-305WBP Black Steel / Plastic ATX Mid Tower Computer Case 450W Power Supply Intel Core i7-2600 Sandy Bridge 3.4GHz (3.8GHz Turbo Boost) LGA 1155 95W Quad-Core Desktop Processor Intel HD Graphics 2000 BX80623I72600 16GB Ram OCZ Agility 3 SSD 120GB From some of the posts out there could the UEFI Bios or the Sandy Bridge processor be a culprit here? We just tried the DVD on a different computer and it got past that point with ease. It's a standard Dell build compared to our custom machine. Could it be having difficulty recognizing drivers? How do we get past that?

• Simulating audio playback on headless linux server

  - by afro

  Hi people, We have a headless linux server (Debian 5) we use for runnin integration tests of our web-page code. Among these tests are ones implemented using Selenium, which practically simulates a user browsing our pages and clicking on things. One of these tests is failing now, because it involves starting a flash-based audio player and checking to see whether the progress bar gets displayed properly. The reason this test fails is that there is no way to play the audio, and no sound card on the machine, which has simple webserver hardware. So, my question would be: Is there a simple way of giving a program the impression that its audio output is being processed, and playback is taking place? I don't have to record the playback, or redirect it or anything like that, just a dummy soundcard, like the dummy X-server we aer using, which actually does not need to display stuff. I have tried using JACK, but it's too complicated, and the documentation does not even answer this very simple question. I also installed alsa on the server; it 'pretends' to run, but when a program tries to play audio, just spews error and debug information having to do with the non-existence of a soundcard. It would be really awesome if one of you has a simple answer to this question. Cheers, Ulas

• Triple-monitor set-up (2 unique, 1 cloned): Can a VGA splitter be used on one output of a dual-head

  - by stakx

  Background: I'm currently researching hardware components for some kind of information terminal we're building. This application of ours makes use of three output screens: (1) A touch screen where all user input is made; (2) A regular LCD monitor where the requested information is being displayed; and (3) A projector which displays exactly the same signal as screen (2) does. (All screens will run at the same resolution of 1024x768 btw.) Now I figured that using a dual-head video card would be sufficient, let's say a Matrox P690 low-profile PCI card. This would involve having a Y cable connected to the graphics card itself, then two DVI-to-VGA adapters at each end of the Y cable, and then having a VGA splitter on one of the VGA outputs. The following shows the setup in question: 0--1---------2-> VGA (DSUB-15) \ \ ----2-3---------> VGA (DSUB-15) \ \ -----------------> VGA (DSUB-15) 0: graphics card (LFH60 jack) 1: LFH60 to DVI-I dual monitor Y cable 2: DVI-to-VGA adapters 3: VGA splitter cable Question(s): Will this work? I'm particularly concerned about the following points: Can a low-profile PCI video card output a signal which is strong enough for three monitors (even if it's a dual-head card)? Does the combination of so many adapters and splitter cables work? (The LFH-to-DVI cable comes with the video card) Will the VGA splitter cable degrade the signal on the output screen & projector significantly? (If so, would a USB-powered splitter cable remedy this problem?) I can't possibly expect anyone to answer all those questions, but any input is appreciated.

• Windows 7 restarts while being idle

  - by Ondrej Slinták

  My Windows 7 almost always restarts when I keep it idle for ~20-30mins. It happened randomly before, but lately, if I leave the computer I can be sure it's gonna restart after those 30mins. It never happens when I play games or work tho, just when it's idle. It's a fresh install of Windows 7 64bit. I had also problems while installing it, it always crashed while finalizing the install and I had to reinstall again. Eventually it installed on 3rd or 4th try after I deleted all of my partitions and added them again. I thought it might have been a hardware problem, but temperatures seem to be okay and I have no idea how to track what might have been causing it. Any ideas? I'm running Windows 7 64bit on: Gigabyte EX58-UD4P Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz NVIDIA GeForce GTX 260 6GB of DDR3 1066Mhz RAM WDC WD1001FALS-00J7B0 1TB SATA II I have a very bad feeling it might be something with HDD and its compatibility with Windows 7 as I haven't had those problems for 1 year while I had Vista. Edit: I checked Event Viewer critical errors from this night. PC restarted first time at 11:12pm, then at 3:06am and since then every ~20min until I came back to it. Error message is: The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. Source: Kernel-Power

• Managing disk in a VM

  - by dst

  I'm replacing my two old rack servers with a new one that has plenty of power to take over the functionality my current servers. The server is a 4U rack mount with 16 3.5" SAS drive bays, two 2.5" bays, a Xeon E3-1230v2 CPU and 32GB of ECC RAM. My issue is the following. I would like to have a FreeBSD file server with ZFS managing disks. However, I need other VMs for e.g. a shell/git server, mail server etc. I'm wondering how to deal with the following issues: I want ZFS to fully manage the disks, so I'm not using any hardware RAID. Should I pass the SAS controller directly to the FreeBSD system as passthrough PCI? I want to maximize the reliability of the setup. On what disks should I install the hypervsor and keep server system disks? For (2) I have the option of having a RAID setup on the SAS controller and using that as system disk to store the hypervisor as well as VM images. However, this makes PCI passthrough to the file server impossible. Another option is using the two 2.5" bays. In terms of reliability how are SSDs compared to e.g. WD RE4 disks? Would it make sense to have two SSDs in software RAID as boot disks for the hypervisor or should I just go with e.g. WD RE4 disks in a software RAID setup. I also need to think about where to store the mails for the mail server, but this could be done over NFS between the VMs. BTW, this is for home use, so the load is not really that big. What I'm looking for is best practices for splitting up a server.

• Errors with Using Webcam

  - by C.G.

  I have been having some issues accessing a webcam from my machine. Sometimes (not always) when I run a program that accesses the device (cheese, guvcview, and code using openCV), I get either of two messages, which lead to the program crashing. The first occurs after running the webcam for some time. libv4l2: error dequeuing buf: No such device VIDIOC_DQBUF: No such device The other will occur without even letting me have a chance to run the webcam. libv4l2: error turning on stream: No space left on device VIDIOC_STREAMON - Unable to start capture: No space left on device Occasionally after getting these errors I will also receive a message saying that no such device can be found for subsequent runs. Other than the times that the "No device found" message appears the webcam appears when I use lsusb. My machine runs Linux Fedora 16, and the webcam is a Logitech C920. I do have ffmpeg installed, and I have been able to run the web camera many times in the past without errors. What is particularly puzzling about these errors is that they just sprung up this past weekend. No new software or hardware has been installed on this machine recently; I haven't changed any settings recently either. It could possibly be a driver issue, but I don't know what could have changed which could lead to this issue. Any attempts at researching this problem has been fruitless as this seems to most commonly occur with multiple webcams. I am only working with one device. I'd appreciate any advice for this problem, as this has become a bit frustrating.

• MD RAID 1 with external bitmap doesn't fully resync

  - by user64744

  I have an interesting configuration: dual boot system with a RAID 1 that needs to be visible in both Windows and Linux. The Windows install is Win 7 Enterprise, and the Linux install is Kubuntu 10.04. To get the RAID to work, I set it up using Windows's "Dynamic Disks" RAID 1, and brought it up in Linux using MD with no persistent superblock, and a write-intent bitmap on another partition. (Without this bitmap, MD had no way of knowing that the array was in sync, and would do a complete resync every time the array started.) The array is assembled like so: mdadm --build /dev/md1 -l 1 -n 2 -b /var/local/md1.bitmap /dev/sdb2 /dev/sdc2 I expected that the first time I ran this command, it would resync the array, write out a bitmap with no dirty chunks, and all would be good. This wasn't the case: after completing the resync, the bitmap was mostly clean, but about 5% dirty blocks remained, as revealed by mdadm -X /var/local/md1.bitmap I didn't mount the filesystem on /dev/md1 or touch it in any other way. I then found that stopping and restarting the array: mdadm --stop /dev/md1 mdadm --build /dev/md1 -l 1 -n 2 -b /var/local/md1.bitmap /dev/sdb2 /dev/sdc2 did indeed read in the bitmap, with an ensuing resync that went quickly because most of the blocks were marked clean. The confusing part is that this resync further reduced the number of dirty blocks, but still did not remove all of them. By repeatedly stopping and restarting I could slowly bring the dirty block count down to around 0.6%, where it seemed to level out. Any ideas what could be causing this? It smells to me of a race condition somewhere that leads to blocks either being skipped over during synchronization or not properly cleared from the bitmap, but I really have no evidence to prove this. It doesn't look like hardware issues since both drives are new and have zero read errors and reallocated sectors reported by smartctl -a.

• Is USB supported in safe mode on XP?

  - by Hugh Allen

  According Microsoft, "Universal Serial Bus Devices Do Not Work in Safe Mode" under XP. However, in my testing this is incorrect. USB keyboards, mice and flash drives seem to work fine in safe mode (I made sure the BIOS was not providing support). This makes sense because a failure of a standard input device would be, in Microsoft parlance, a "bad user experience". So, Is USB supported in safe mode on XP? If your answer is no (agreeing with Microsoft), please provide a test case, preferably in a virtual machine, where a standard HID keyboard or mouse fails. Please state hardware / BIOS / OS configuration. Note that you will need a PS/2 keyboard attached in addition to your USB device(s) in order to use the boot menu. Virtual machine software usually emulates a PS/2 keyboard. Alternatively, you could add the /safeboot switch to boot.ini. If your answer is yes, please provide a link to some supporting documentation (either from Microsoft or someone authoritative). Your answer might be "devices X, Y and Z are supported but nothing else", in which case also give a link.

• Using virtualization infrastructure for J2EE application distribution- viable alternative?

  - by Dan

  Our company builds custom J2EE web solutions. At the moment, we use standard J2EE distribution mechanisms (ear/war archives). Application servers are generally administered by our clients' IT departments and since we do not have complete control over the environment, a lot of entropy can be introduced into the solution. For example: latest app. server patch not applied conflicting third party libraries inside the app. server root server runtime and tuning parameters not configured (for example, number of connections in database pool) We are looking into using virtualization infrastructure for J2EE application distribution. Instead of sending the ear/war archive, we’d send image with application server node and our application preinstalled. Some of the benefits are same as using with using virtualization infrastructure in general, namely better use of hardware resources. For us, it reduces the entropy of hosting infrastructure - distributing VM should be less affected by hosting environment. So far, the downside I see can be in application server licenses, here they will have to use dedicated servers for our solution, but this is generally already done that way. Also, there is a complexity with maintaining virtualization infrastructure, but this is often something IT departments have more experience with than with administering and fine-tuning J2EE solutions. Anyone has experience with this model? What are the downsides? Will we not just replace one type of complexity with other?

• Splitting build cross the network?

  - by Dandikas

  Is there a known solution for splitting build process cross the network machines? Use case: We are an average software development company. We own around 50 development workstations (Quad Core 2.66Ghz, 4 GB ram, 200 GB raid). No need to tell that at any single moment not every machine is loaded to the max. There are 5 to 15 projects running simultaneously at any single moment. Obviously all of them are continuously build on server, than deployed to proper environment. Single project build is taking from 3 to 15 minutes. The problem: Whenever we build 5 projects in a row the last project is going to be ready after around 25 - 50 minutes. Building in parallel does not solve the problem (build is only a part of the game, than you need to deploy, run tests etc.) YES the correct solution is to add another build server, but "That involves buying new Expensive hardware, and we already spent a lot!". Yea, right(damn them)! Anyway. What about splitting build among developers workstation? Lets say whenever we need to build project "A" we check 5 workstations and start build on all that are not overloaded. The build can be canceled by a developer if he really needs all the power of his machine as long as there is at least 1 machine that is still building. After build is finished deployment can be performed to a proper environment (hosted on some server, not on workstation :) ). The bigger the company the more this makes sense to me. Anyone tried something like this? Are there any good practices? Any helpful software?

• My client's solution of a Windows SBS 2011 VM on an Ubuntu host and VirtualBox is pinning the host CPU

  - by Scott Stamp

  Here's my situation, I've got a client hosting two servers (one VM), with the host providing VMware Zimbra, the other Windows Small Business Server 2011. Unfortunately, the person before me had configured this setup as follows. Host: Ubuntu Desktop Edition 10.04 (I know, again, not my choice) running VMware Zimbra 8GB of RAM On-board RAID1 of two 320GB Seagate Barracuda drives for the OS Software RAID5 of four 500GB WD Caviar Black drives on MDADM for bulk storage (sorry, I don't know the model #) A relatively competent quad-core Intel Core i7 CPU from the Nehalem architecture (not suspicious of this as the bottleneck) Guest: Windows Small Business Server 2011 4GB of RAM Host-equivalent CPU allocation VDI file for OS hosted on the on-board RAID, VDI file for storage hosted on the on-board RAID For some reason when running, the VM locks up when sitting nearly idle, and the VirtualBox process reports values of 240%+ in top (how is that even possible?!). Anyone have any ideas or suggestions? I'm totally stumped on this one. Happy to provide whatever logs you'd like to take a look at. Ideally I'd drop VirtualBox and provision this with VMware Workstation, but the client has objected to the (very nominal) costs involved. If hardware needs to be purchased to help, it will be, but we're considering upgrades a last-resort at this time. Thanks in advance! *fingers crossed*

• Data Store/Volume disconnecting. How to resume copy of VMDK?

  - by Serge

  I'm having an issue with my ESXi 4.1 hosts losing the datastore with FC SAN after a power outage. All 3 hosts disconnect so it's definitely a SAN issue. I've tried to resolve the issue on the SAN side with the SAN software support and Adaptec hardware support. No luck there. So I'm stuck with a SAN that will randomly disconnect the volume. I need to get the virtual machines (VMDK files) from the datastore. The problem is I can only get 5-20% before the data store disconnects. I have backups that are slightly older that I can use to replicate the VMDK differences to. What has not worked so far: Powering up the VMs, will boot up for 5-15 minutes then freeze vCenter migrate or clone of VM, will fail after similar period of time vCenter copy/paste of VMDK. Was able to get one 30GB VMDK and no luck after that. vMware Data Recovery. Fails at low %, can't resume, so next backup starts from begining. Veeam Backup & Recovery. Same as above, no resume function. If I can just find a backup solution that will resume from the failed spot that would solve my issue. Anyone have any ideas that I could try? EDIT 1 The SAN is Open-E DSS 6 running on a Supermicro 24 drive enclosure with 4 port Qlogic FC. Adaptec 52445 RAID card.

• Can't upgrade NVIDIA GeForce 310M display driver on Acer Aspire 5745PG

  - by Emerson

  I've been for days already trying to update my video driver. I have an Acer Aspire 5745PG with a "NVIDIA GeForce 310M" board, and I was trying to run Sony Vegas video editor with Boris Continunn plugins. It happened that some of the plugins, like BCC Text Extrude wouldn't work, showing the message "Insufficient depth resolution to run Blue". I then read somewhere that updating the display driver would do the trick. That was when my nightmares started, I lost already good 3 nights trying to sort this out, without success :( The display driver that was before (and that I current have after restoring) was the version 8.16.11.8997. First thing I tried was downloading the 8.17.12.6619 driver directly from Acer, which was shown as the latest version from Acer website: http://support.acer.com/product/default.aspx?modelId=2466 Running it would say "Diver Package Failure - Setup failed to read the required Display Driver to be used with this package" I then tried directly the NVIDIA own driver, which the latest was version 296.10: http://us.download.nvidia.com/Windows/296.10/296.10-notebook-win7-winvista-64bit-international-whql.exe That gave me similar error message :/ So after some researching I found out that some people had the same issue and they had to change the configuration file to allow the installer to recognize this NVIDIA board: http://forums.nvidia.com/index.php?showtopic=222904 That topic said to look for the "Device Instance Id" property of the "NVIDIA GeForce 310M" display , which I couldn't find, instead I found the "Hardware Id", which seemed to be the right one. I followed the instructions and changed the inf file first for the Acer installation, and after for the NVIDIA own driver. It actually managed to go ahead with the installation in both instances, but the only thing I got was a black screen, while the computer still apeared to be running fine. I had to hard reset, and then it would come back with generic vga driver. I could only get my display back using the recovery function. I imagine thousands of this notebook was sold, and it can't have its driver updated?? Could someone help me with this?? Thanks Echo

• IP Phone over VPN - one way calls unless default route?

  - by dannymcc

  I have come across a strange problem with our VPN and BCM 50 (Nortel/Avaya) phone system. As you can tell by my other questions I have been doing some work on setting a VPN up from one location to another and it's all working well. With one exception. We have an IP phone that is connected at the remote location, straight to a router which has a VPN tunnel to our main practice. The phone works mostly, but every few calls it turns into a one way call. As in, the caller (from the remote phone) can't hear the receiver- but the receiver can hear the caller. This is fixed by setting the VPN tunnel to be the default route for all traffic. The problem with fixing it that way is that all traffic then goes through the tunnel which slows internet access etc. down considerably. The router is set to send the following over the VPN: 192.168.1.0/24 192.168.2.0/24 192.168.4.0/24 The IP of the remote location is: 192.168.3.0/24 The remote router (where the phone is) is a Draytek 2830n, and the local router (at the main practice) is a Draytek 2820. We are using an IPSec tunnel with AES encryption <- as a result of a previous answer pointing to the incompatibility in the hardware encryption. Any advice would be appreciated!

• I/O Error on LG GSA-H12N DVD drive on Windows 7

  - by Ashwin

  I am facing an I/O Error when I try to burn DVD data discs on my LG GSA-H12N DVD drive on Windows 7. Note that I was able to do this same operation on the same hardware/software just a day earlier without any problems, but with Windows XP. The only change (AFAIK) has been the installation of Windows 7 to replace Windows XP on this PC. Here is the error I get when I try to burn a DVD data disc using CDBurnerXP 4.2.7.1801: Burning error occured An error occured while burning the disc. Most likely the disc is not usable. Usually these errors happen if the inserted media is not compatible to the drive or of poor quality. (devNTSPTI_IO_Error) Could not write to Disc (LBA: 52864 Length: 32). SCSI Pass-through Interface I/O Error. - 0xFF045D Note that there can be no problem with the discs since I have been using the same discs (from the same box) just before the Windows 7 installation with no problems. The only change has been Windows 7. I tried InfraRecorder v0.5 and ImgBurn v2.5 and got similar I/O errors: Note that Windows 7 lists the LG GSA-H21N drive as being compatible (see this link). I also checked the LG Drivers website and using the firware update from there updated the drive firmware from version UL01 to UL02. But, even this has not helped. The drive reads DVDs without any problem, but continues to produce coasters. Could someone help me figure out what is the problem? Thanks :)

• MSSQL error: consistency-based I/O error - can it be caused by an MSSQL or OS problem?

  - by Philipp Keller

  This is what I saw in the windows error log: SQL Server detected a logical consistency-based I/O error: incorrect checksum (expected: 0x19fedd20; actual: 0x19fed5e3). It occurred during a read of page (1:1764) in database ID 6 at offset 0x00000000dc8000 in file 'D:\mssql\local_repository_pbdiffimport.mdf'. Additional messages in the SQL Server error log or system event log may provide more detail. This is a severe error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online. I ran dbcc checkdb which told me I should restore with option REPAIR_ALLOW_DATA_LOSS, so I eventually ran DBCC CHECKDB (my_db_name, REPAIR_ALLOW_DATA_LOSS) WITH NO_INFOMSGS But that resulted in about 2'000 rows being lost. I restored a backup but now I'm afraid this will happen again since we already had a consistency problem in the same database about 2 weeks ago but then it happened in an index (recreated indexes solved the problem). We have investigated the discs - RAID5 looks good, no errors, and also none of the disc-check-utilities have revealed any hardware problem. Can this be caused by OS (Windows Server 2003) or by MSSQL (MSSQL Server 2005)?

• VPN Setup: Mac OS X and SonicWall

  - by noloader

  I'm trying to get VPN access up and running. The company has a SonicWall firewall/concentrator and I'm working on a Mac. I'm not sure of the SonicWall's hardware or software level. My MacBook Pro is OS X 10.8, x64, fully patched. The Mac Networking applet claims the remote server is not responding. The connection attempt subsequently fails: This is utter bullshit, as a Wireshark trace shows the Protected Mode negotiation, and then the fallback to Quick Mode: I have two questions (1) does Mac OS X VPN work in real life? (2) Are there any trustworthy (non-Apple) tools to test and diagnose the connection problem (Wireshark is a cannon and I have to interpret the results)? And a third question (off topic): what is broken in Cupertino such that so much broken software gets past their QA department? EDIT (12/14/2012): The network guy sent me "VPN Configuration Guide" (Equinox document SonicOS_Standard-6-EN). It seems an IPSec VPN now requires a Firewall Unique Identifier. Just to be sure, I revisited RFC 2409, where Main Mode, Aggressive Mode, and Quick Mode are discussed. I cannot find a reference to Firewall Unique Identifier. I think I am screwed here: I am trying to connect to a broken (non-standard) firewall, with a broken Mac OS X client. Fortunately, I can purchase VPN Tracker Personal (a {SonicWall|Equinox}-authored client) for $129US from Equinox. So much for standards....

• Recovering drive via boot to Win7 setup command prompt

  - by Valamas

  I am trying to recover data from two old IDE drives. Drive1 has been successful, but something is wrong with Drive2. It does not appear as a drive letter. Due to limited legacy hardware, the only way i can see these drives is to boot using windows 7 setup and goto the command prompt. Without going further as to why, my question is how i can access the data in this command prompt. I discovered DISKPART command and while a first time user, it looked like something that can fix my problem. Here are the results of my diskpart commands. At the bottom is a image of the commands taken with a camera. The Drive2 is present because when using the diskpart command, I can see it. How can I copy the information using a robocopy script if the drive letter is not available? how can I assign a drive letter? Is there any repair command I need to execute? When i execute DISKPART, the following is what i see. DISKPART> LIST DISK Disk### Status Size Free Disk 5 Online 37 GB 2048 KB So then I select disk 5. DISKPART> SELECT DISK 5 "Disk 5 is now the selected disk" When I list partition DISKPART> LIST PARTITION Partition ### Type Size Partition 1 Primary 101 MB Partition 2 Primary 37 GB So I select partition 2 "Partition 2 is now the selected partition." I then try to assign a drive letter DISKPART> ASSIGN LETTER=G "There is no volume specified." "Please select a volume and try again." When i list volume the drive is not present. DISKPART> LIST VOLUME Result of the above commands

• Xmonad on windows laptop

  - by Kevin L.

  I'm a Linux developer in the market for a laptop. 90% of my time is spent in Emacs, the terminal, and Google Chrome, and I want to use them within the excellent Xmonad tiling windows manager. Given these constraints, I can only see two options: Run Linux on a laptop Run Windows on the laptop, and spend all of my time working within a Linux VM. Years of experience suggest that the first option will take many frustrating hours and probably be suboptimal w.r.t. battery life, wifi, and fn keys like screen brightness or audio adjustment. For the second option, what would be the ideal setup? I've had a lot of luck with Cooperative Linux on my Samsung NC-10 netbook (Windows XP), but I would have to setup the X11 server myself. What about using VirtualBox (which includes the guest VM's GUI)? Has anyone tried this? Hardware-wise, I'm looking for something in the "Macbook Air killer" category; Samsung Series 9 laptop, Lenovo IdeaPad U300s, &c. (i.e., matte screen, 5h+ battery life, 3ish pound weight). Price is not a consideration; any suggestions?

• Debugging Windows PC freeze

  - by Violet Giraffe

  I have a problem with my computer, would appreciate any hints/ideas. It usually begins not immediately after booting Windows, but at some unpredictable point in time, which doesn't seem to correlate with any specific actions of mine. First sign of a problem is process System starting to consume 25% CPU time steadily. I have a quad-core CPU, so it might be one thread working non-stop. At this point micro-freezes start to occur - screen stops refreshing, but if I have, say, music player running - it continues playing. If I try to do something between the freezes, like open Start menu, it will freeze completely and forever. If I press reset button the PC will shut down and then start cold, as opposed to usual reset behavior (which doesn't include PC shutting down). I have noticed that full restart upon reset is usual for hardware problems, but I think this problem isn't related to at least motherboard-CPU-RAM-videoadapter. It certainly isn't caused by overheating. One very important not is that it seems to be related to Windows hosted WLAN network: I have USB Wi-Fi dongle and have configured a hosted network to share cable Internet connection with Wi-Fi devices. I am not 100% certain there's a strong connection, but in 9 or 10 cases when I enabled the network (by executing netsh wlan start hostednetwork), it did freeze eventually (sometimes within minutes of starting the network, sometimes within hours), and on at least 10 days when I didn't start the network it never froze, no matter how I used the computer). There are no critical/error entries in the events log that I can suspect as being related, only regular stuff like "driver not loaded". I have found no critical/error events that are being logged around the time of freeze occurring and are not logged during normal boot without starting the WLAN.

• RTL8192SU + RTL8191E Linux Issue Installing Driver

  - by s32ialx

  OK I've read tons of fourms of people getting the onboard RTL8191E working and the RTL8192SU working dif is U = USB they are both N and i have both Toshiba L500D-00T pre-installed Win Vistax64-HP and i have obtained the free Win7x64-HP upgrade the onboard wificard sucks and can't hold a stable connection for more then 20minutes in windows but the usb is amazing. Now problem is i tried both Ubuntu and Mandriva with no resolve the issue is the onboard drive detects and actually SHOWS that it's there but no wireless networks detect so it's saying no SSID's are broadcasting which i know is a lie since I'm running a 2wire bell dsl modem with built in wifi and a Linksys wrt54g w/ DD-WRT firmware and both are broadcasting fine. Why don't i use the USB? new in Mandriva Linux Control Center 2010.0 it shows up in Other/Unknown as RTL8191S WLAN Adapter and on the right pane this shows up Identification Vendor: ?Manufacturer Realtek Description: ?RTL8191S WLAN Adapter Media class: ? Connection Bus: ?USB Bus PCI #: ?1 PCI device #: ?5 Vendor ID: ?0x0bda Device ID: ?0x8172 Sub vendor ID: ?0x0000 Sub device ID: ?0x0000 Misc Module: ?rtl819xU In the hardware device manager in mandriva it shows up as unknown but shows that it's realtek and that it's a 8192 chipset. but no option to for a driver install and when i do a make in terminal i get this error and no clue what it means [root@John-PC rtl8192se_linux_2.6.0010.1020.2009_64bit]# make make: *** /lib/modules/2.6.31.12-desktop-3mnb/build: No such file or directory.

• Backup plan for linux webserver in small business?

  - by radman

  Hi, I am currently in the process of writing a backup plan for the webserver in use by my business. I am very new to this area and have a few ideas about how things should work but am unsure of what tools to use and what sort of restore process is appropriate. I'm looking for something relatively simplistic and it doesn't have to be 100% paranoid just enough to give me a reliable backup. Speed is not of the essence and there is not going to be a live fallback in place. The backup will be onto a single hdd that will be stored onsite (no option for offsite as yet). Backups will be taking place weekly. I am constrained by both time and money which is why I'm aiming for a good enough solution. Is taking an image of the webserver system drive periodically and using that as the backup appropriate? Should I be testing that the backups restore correctly every time that I perform one? This is a bit broad but what setup would you use if you were in my place, given the services I am running? Should I add additonal machines and split the services? Any advice is much appreciated! See below for server details Webserver Platform Linux Ubuntu server Running mail-server svn-server mediawiki wordpress apache-webserver Hardware single 500gb sata drive Architecture Single machine behind router (with firewall) accessible to the internet.
