• Created new torrent but client unable to find seeds

  - by ehfeng

  I tried creating a new torrent, using uTorrent, following the directions from torrentfreak (http://torrentfreak.com/how-to-create-a-torrent/). I used a bunch of trackers (just in case any individual one was having troubles) and uTorrent shows it as "seeding" with 100% of the file. It shows: seeds 0(1), peers 0(0). http://exodus.desync.com/announce http://eztv.tracker.prq.to/announce http://open.tracker.thepiratebay.org/announce http://www.torrent-downloads.to:2710/announce http://denis.stalker.h3q.com:6969/announce udp://denis.stalker.h3q.com:6969/announce http://www.sumotracker.com/announce I've also attempted to remove the torrent and then re-add the torrent, pointing it to my already existing files, forcing uTorrent to recheck the files and then begin seeding. Yet when I share the .torrent file with my other computer and attempt to download, it is unable to find any peers or seeds. To confirm that both clients are working, I downloaded a torrent on both computers, using their respective clients, using torrents I found on isohunt. This tells me that there must be something wrong in how I'm creating my torrents. Any help is appreciated.

• Poor NFS Performance: OpenFiler

  - by Safin09

  Good Day Everyone, I have an issue with OpenFiler, a Linux-based operating that converts a computer system into a SAN/NAS appliance. Here is the problem. In my environment we have two Netapp Storevault 500 appliances that I normally perform backups to a NFS share. There are two backup cronjobs that use ghettoVCB to backup two groups of VM's. One group is a pool of 3 VMs. This takes 13 mins to complete. A second job that backups a pool of 5 VMs to a 2nd Storevault appliance which takes 2 hours. We then installed Openfiler on a old server that has 2 core Xeon processors. There is a software RAID 5 process in place. When performing the same backups to a NFS Openfiler share, the first backup job, which takes 13 mins, takes around 4 hours. The second backup job, which takes 2 hours, takes almost 10 hours to complete. This is unacceptable!!!! Especially considering the strain placed on the host ESX Server. I assumed that because of the software RAID 5, the overhead on the CPU explained the long backup times. I then installed Openfiler on a 2nd server, an IBM x306 machine which has a P4 Intel processor. This time no software RAID or any RAID at all. A single 750GB hard drive that contained the OS and the rest of the disk uses to backup VMs to a NFS share. I performed the first backup job of the pool of 3 VMs. This time the backup job took 1 and 1/2 hours to complete instead of 13 mins!!!!!!!!!! Is Openfiler simply poor at being an NFS Server!!!!!!!!!!!!! Has anyone else had these issues with Openfiler?

• Using Virtualbox Bridge Networking fails connection from Guest OS to Oracle XE running on Host

  - by Licheng

  I am trying to make a JDBC connection from a VirtualBox Ubuntu Guest OS to an Oracle XE database running o Host. However, the connection is refused. Here are the details of my environment: VirtualBox: 4.1.4 Host OS: Windows 7 Guest OS: Ubuntu server 11.4 Networking mode: Bridged network Oracle XE database running on Host Issue: WebLogic server runs on the Ubuntu virtualbox. It attempts to connect to an Oracle XE database running on the Host OS (windows 7) with listening port 1521. On the Guest OS (Ubuntu), I am able to ping the Host computer from the Guest OS. However, when I configured a JDBC data source on the WebLogic server on the Guest OS to connect to the Oracle XE, connection took a long time, and eventually I received an "IO Exception: The Network Adapter could not establish the connection". When I tried "telnet host-ip 1521", no connection was established. With Bridge networking, I can make bi-directional connections between the host and the guest OS (e.g. connection through ssh and ftp). Is there anything I missed in the setup of Bridge networking and the guest/host OS? Note that I was able to make the same connection within a normal networking environment (i.e. not using virtual box). I am not sure whether Bridge networking is a good option for the work described above. Should I use host-only networking mode? If so, any specific configurations I need to perform? I read through the Virtual box document on setting up the host-only network, however, it lacks of details. I followed the procedures described in the manual, and couldn't even connect to the host. Could some experts here enlighten me on this issue? Much appreciated. Licheng

• Can't remotely connect through SQL Server Management Studio

  - by FAtBalloon

  I have setup a SQL Server 2008 Express instance on a dedicated Windows 2008 Server hosted by 1and1.com. I cannot connect remotely to the server through management studio. I have taken the following steps below and am beyond any further ideas. I have researched the site and cannot figure anything else out so please forgive me if I missed something obvious, but I'm going crazy. Here's the lowdown. The SQL Server instance is running and works perfectly when working locally. In SQL Server Management Studio, I have checked the box "Allow Remote Connections to this Server" I have removed any external hardware firewall settings from the 1and1 admin panel Windows firewall on the server has been disabled, but just for kicks I added an inbound rule that allows for all connections on port 1433. In SQL Native Client configuration, TCP/IP is enabled. I also made sure the "IP1" with the server's IP address had a 0 for dynamic port, but I deleted it and added 1433 in the regular TCP Port field. I also set the "IPALL" TCP Port to 1433. In SQL Native Client configuration, SQL Server Browser is also running and I also tried adding an ALIAS in the I restarted SQL server after I set this value. Doing a "netstat -ano" on the server machine returns a TCP 0.0.0.0:1433 LISTENING UDP 0.0.0.0:1434 LISTENING I do a port scan from my local computer and it says that the port is FILTERED instead of LISTENING. I also tried to connect from Management studio on my local machine and it is throwing a connection error. Tried the following server names with SQL Server and Windows Authentication marked in the database security. ipaddress\SQLEXPRESS,1433 ipaddress\SQLEXPRESS ipaddress ipaddress,1433 tcp:ipaddress\SQLEXPRESS tcp:ipaddress\SQLEXPRESS,1433

• DD-WRT PPTP VPN problem

  - by Tobias Tromm

  I try to configure a DD-WRT as a PPTP client. The VPN Server is Windows Server 2003. This is my scenario: The Windows 2003 Server has set to give to the VPN Client the 10.0.0.81 fixed IP and to add a network route to the remote home. At the remote home I have changed the PPTP Options at DD-WRT to make the connection. The VPN connection is successfully established. ...and Windows successfully add the route to the remote home 192.168.2.X. From the remote home I can successfully access any computer from the VPN server side. The problem is when I try to access the remote home from the Server side. From Server side I only can access\ping DD-WRT ( by VPN Client IP - 10.0.0.81). What's wrong? How I need to do to be a site-to-site VPN? This is what happen when I try to tracert the remote home from local home.

• SIP and NAT routers?

  - by OverTheRainbow

  Hello SIP was not built with NAT routers in mind, and I'd like to get to the bottom of this issue to check what needs to be done on all devices so it works with NAT routers, and understand in what context it just can't be used and I should check more NAT-friendly alternatives like IAX. A picture being worth a thousand words, here's the layout I need to use: http://img62.imageshack.us/img62/4077/sipandnatrouters.jpg The PBX server is located in the private LAN behind a NAT router connected to the Internet (I know it'd be easier if it were located in the public network, but this router doesn't support DMZ's so the server has to be in the private network) A couple of (soft|hard)phones are located on the same LAN and connected to the PBX server, along with a PSTN gateway (Linksys 3102 or a Digium PCI card) Remote users using (soft|hard)phones are located somewhere on the Net with dynamic IP's and are also located behind NAT routers I may or may not have control over the local NAT router where the PBX server is located, but I have no control over the remote NAT routers, either because the users don't have the computer knowledge to map ports or because the routers are off-limit (eg. web cafés, hotel LAN's, etc.) Is it possible to configure the PBX server, the (soft|hard)phones, and the PSTN gateway so that the all conversations work fine, no matter the endpoints (POTS caller/local phone, POTS caller/remote phone, local phones, remote phone/local phone)? In which cases may I expect problems, and are there solutions? FWIW, I'm leaning toward using Freeswitch, but I could end up using Asterisk if there are technical advantages to it in this context. Thank you for any info.

• Linux error when resume from RAM

  - by TuxPotato

  The last two times that I have resumed my laptop from sleep, it has hung and given me this set of errors: [drm:atom_op_jump] *ERROR* atombios stuck in loop for more than 1sec aborting [drm:atom_execute_table_locked] *ERROR* atombios stuck executing E692 (len 460, WS 0, PS 4) @0xE6D3 hda_intel: azx_get_responce timeout, switching to single_cmd mode: last cmd=0x01170700 ata6: softreset failed (device not ready) ata4: softreset failed (device not ready) [drm:atom_op_jump] *ERROR* atombios stuck in loop for more than 1sec aborting [drm:atom_execute_table_locked] *ERROR* atombios stuck executing E692 (len 460, WS 0, PS 4) @0xE6D3 The last two messages repeat two more times. The first time this happened, Linux's Magic SysRq worked and did a soft reboot, and after that everything was fine till it went to sleep again. It wakes up and gives me this. Here are the laptop stats: Toshiba Satellite L455D-S5976 AMD Sempron SI-42 Processor 2GB DDR2 RAM HD TruBrite Display ATI Radeon Graphics (integrated) Running Ubuntu 10.10 32 bit I'm not sure about the hard drive, but its a 250GB drive with one NTFS partition, two Hidden NTFS, one Linux Swap, and one Ext4. Can someone tell me whats wrong with my laptop? NOTE: This only happens when I close the screen. My computer doesn't go to sleep with the screen open.

• In Windows 7, why can't I use perfmon against a remote server?

  - by SomeGuy

  I am on Windows 7 and trying to run perfmon against Windows 2003 and Windows 2008 servers. I am running into the same issue with all remote machines. When creating a data collector set, I specify a domain account that is in the administrators group on the remote machines (and "Performance Log Users" and "Performance Monitor Users" to be safe). On the "Available Counters" screen, When I type in a remote computer name, PerfMon locks up for a good 2-3 minutes before I can add any counters. I can then save the collector set. However, when I save it, the go/stop buttons are disabled if I click the set in the left panel, and missing if I click the Data collector set itself in the right panel. See the screens below. I can run data collector sets against my local machine with no problem. I am opening perfmon with my local account in both scenarios. I also have Remote Registry Service started on each remote machine. What is going on?

• Use synergy with Physical KVM

• What's hogging my CPU?

  - by endolith

  Ubuntu's System Monitor applet shows 100% CPU usage continuously. If I click it, the resources tab shows it at 100% continuously, too. If I go to processes, though, to find out which process is the culprit, there is nothing above 10%. If I run top there is nothing above 10%. I try killing lots of things, but it continues at 100%. How can I find out what's hogging the CPU? This is an unusual situation on a computer I use daily, that normally only hits 100% CPU when I'm doing something that requires it (like loading 32 Firefox tabs) after which it goes back to a normal idle level. It's not a new install or anything. It shouldn't be maxed out. I'm not sure when it started or if I changed something that caused it to happen. Normally I would use top or System Monitor and find the process that had gone out of control, but I can't find anything with those tools this time. It persists after reboots and everything. And the processor is obviously hot, so it's not an erroneous reading. Update: I tried killing any process I saw active again, and killing vino-server finally fixed the problem, even though it never went above 5%. I had enabled Remote Desktop a few days ago (and have obviously now disabled it). How did it manage to use 100% CPU while top only showed it as 5% or so? How do I identify the culprit in the future? Looks like I'm not the only one: Still a problem in both jaunty & karmic. Interestingly, both System Monitor & htop do not show the sum of individual processes being anywhere near 100% cpu.

• Windows 7 disk backup and clone for deployment to multiple systems

  - by gregmac

  I'm in the process of deploying some new PCs (there's only 8), all identical hardware. What I'd like to do is install Windows 7 (64bit), join to domain etc, install a bunch of other software, and then clone that drive to multiple other machines. I'd also like to be able to use it as a backup image, so the machine can be restored back to that image at some future date. I understand this involves at least sysprep, but I am confused after reading some tutorials that talk about using Windows Automated Installation Kit, or hacks with the registry and custom-build batch files. This process seems overly complex to me: I did something similar 10+ years ago, and and don't remember it being this bad. Surely things have improved in a decade? There's also some products that involve having network servers running deployment software, network boot, etc etc.. this is way more than I want to set up. My systems are all identical hardware. Is there a simplified way to clone PCs? Preferably (since I'm a lazy developer, and not an IT admin) I'd like to find some off-the-shelf product that I can run after I get the machine setup, that will spit out a bootable DVD I can run on all the other systems, which will boot up, ask for a computer name, join it to the domain, and that's it. Does such as product exist?

• Dynamically add Server 2008 NLB Nodes

  - by Nick Jacques

  Hi All, I have a small NLB cluster for Terminal Servers. One of the things we're looking at doing for this particular project (this is for a college class) is dynamically creating Terminal Servers. What we've done is create policies for a certain OU, that sets the proper TS Farm properties and installs the Terminal Server role and NLB feature. Now what we'd like to do is create a script to be run on our Domain Controller to add hosts to the preexisting NLB cluster. On our Server 2008 R2 Domain Controller, I was thinking of running the following PowerShell script I've kind of hacked together. Any thoughts on if this will work? Is there any way I can trigger this script to run on the DC once all the scripts to install roles are done on the various Terminal Servers? Thanks very much in advance!! Import-Module NetworkLoadBalancingClusters $TermServs = @() $Interface = "Local Area Connection" $ou = [ADSI]"LDAP://OU=Term Servs,DC=example,DC=com" foreach ($child in $ou.psbase.Children) { if ($child.ObjectCategory -like '*computer*') {$TermServs += $child.Name} } foreach ($TS in $TermServs) { Get-NlbCluster 172.16.0.254 | Add-NlbClusterNode -NewNodeName $TS -NewNodeInterface $Interface }

• Ping: sendmsg: operation not permitted error after installing iptables on Arch GNU/Linux

  - by estol

  Yesterday I got a new computer as my homeserver, a HP Proliant Microserver. Installed Arch Linux on it, with kernel version 3.2.12. After installing iptables (1.4.12.2 - the current version afaik) and changing the net.ipv4.ip_forward key to 1, and enabling forwarding in the iptables configuration file (and rebooting), the system cannot use any of its network itnerfaces. Ping fails with Ping: sendmsg: operation not permitted If I remove iptables completely, networking is okay, but I need to share the Internet connection to the local network. eth0 - wan NIC integrated on the motherboard (no idea of vendor, probably HP). eth1 - lan NIC in a pci-express slot (Intel Gigabit CT Desktop http://www.intel.com/content/www/us/en/network-adapters/gigabit-network-adapters/gigabit-ct-desktop-adapter.html) Since it works without iptables(server can access the internet, and I can login with ssh from the internal network), I assume it has something to do with iptables. I do not have much experience with iptables, so I used these as reference (separate from each other of course...): wiki.archlinux.org/index.php/Simple_stateful_firewall#Setting_up_a_NAT_gateway revsys.com/writings/quicktips/nat.html howtoforge.com/nat_iptables On my previous server, I used the revsys guide to set up nat, worked like a charm. Anyone experienced anything like this before? What am I doing wrong? Thanks, estol

• Installing SATA dvd burner on machine with no spare SATA ports/connectors

  - by Faheem Mitha

  Greetings. I have the following motherboard Tyan Thunder K8WE S2895A2NRF Motherboard - extended ATX - nForce Pro 2200/2050 - Socket 940 - UDMA133, Serial ATA-300 (RAID) - 2 x Gigabit Ethernet - FireWire - 6-1 channel audio This is part of a computer that was assembled in the winter of 2006/2007. The user manual says the following with regard to SATA Integrated SATAII Generation 1 Controllers (from NForce Professional 2200) Two integrated dual port SATA II controllers Four SATA connectors support up to four drives 3 Gb/s per direction per channel NvRAID v2.0 support Supports RAID 0, 1, 0+1 and JBOD. I just purchased a SATA DVD burner. Here is the page for the product http://www.amazon.ca/gp/product/B002QGDWLK/ The problem I am facing is that I already have 4 SATA drives installed. I don't want to remove any of them. However, I want the DVD burner above installed as well. The person I am consulting with here (Bombay, India) tells me that my four available SATA ports are filled, and that my only option is to install a SATA card into the one free PCI slot on the motherboard. However, he says that with this setup I will not be able to boot from the DVD drive. Are these statements correct, and what are my other options if any? Even it the statements in the last para are true, I suppose I could use one of the motherboard connectors/ports there are currently being used with the hard drives with the DVD drive, and use the "add-on" connector with one of the hard drives. Not all the 4 hard drives need to be bootable. BTW, despite having read through http://en.wikipedia.org/wiki/Serial_ATA#Cables.2C_connectors.2C_and_ports I am fuzzy on the differences between connectors, cables and ports. Thanks in advance.

• pfsense single MAC is listed with several IP's in ARP table

• How To Fix Samba File Permission Issues in Mac OSX

  - by user1867768

  I've had this problem for a long time, here is the basics of it... I use a mixed environment of Windows 7/8 computers with Mac OSX Lion/Mountain Lion. Whenever a Windows computer creates a file on a SMB share on the Mac it no longer has group permissions, only the person who created or updated it can access it. My solution has been to go onto the Mac system and reset permissions for the entire directory structure then everyone can see it again. About the only thing on this that I can find was for OSX pre Snow Leopard that mentioned editing the SMB.CONF file to fix their particular problem (similar to mine, http://www.gladsheim.com/blog/2009/09/19/osx-leopard-and-samba-permissions/). The problem is that now Lion and Mountion Lion no longer have an SMB.CONF file (another web search pointed to the com.apple.smbd.plist (http://kidsreturn.org/?s=smb.conf) but it's an XML file now and I'm not clear on what should be done to THAT to fix the problem. So, short of me writing an Applescript to run every hour to fix permissions, does anyone know a solution to this very frustrating problem? Thank you in advance for any advice or solutions you can offer!

• Upgrading Visio 2000 to Visio 2007

  - by dirtside

  I have Microsoft Visio 2000 SR 1, and recently purchased Microsoft Office Visio Standard 2007 with the understanding (supported by the product info and some other research) that I'd be able to upgrade. However, when I install 2007, it tells me it can't find a previous install of Visio, but... it's right there! Here's the exact message: "Setup can't find a version of Microsoft Office on your computer. If Office is installed on a disk or network share, click the browse button to select the appropriate disk or share... (etc.)" No matter which directory or drive I pick (various Office installs, the old Visio install, various subdirectories) it gives the following message: "The path you have chosen does not point at a qualifying upgradeable product. Click 'Retry' to try again or 'Cancel' to quit setup." Any ideas? This is a legit copy of Visio 2007 (purchased from Amazon) and the copy of Visio 2000 is legit as well. I'm not sure what exactly the installer is looking for that it would consider a "qualifying upgradeable product". A specific file?

• Finding a backup and synchronization solution

  - by Andrea Zilio

  I'm having difficulties to find a backup and synchronization solution with the following characteristics: Cross-platform: Windows, Linux, Mac Offsite backup (so Internet Backup) Data deduplication Transfer only new/modified bits of modified files Secure: Data encrypted before leaving computer Maintain multiple versions of files (even deleted files) Folder synchronization integrated with backup and across multiple computers connected to the internet (not necessarily in the same LAN) I think that the Folder Sync feature needs a better explanation. The use case is this: you have a desktop pc and a laptop. The desktop pc contains a folder with some files and this folder is part of the backup (so it was selected to be backed up). The laptop does not contain that folder or that files at all. Then you're abroad with your laptop and you need that folder. So you want to be able to open the backup program, select that folder from the backup and download it in your laptop mantaining it synchronized with the backed up version. When you then come back home and switch on your desktop pc you want the folder we're talking about to be updated in the desktop PC. Does anyone knows any service with all these features? I've only found SpiderOak to support all the features I've mentioned but I'm not completely satisfied by the time taken to complete a backup. Sometimes it seems to hang for minutes with no reasons at all and folder synchronization occurs only after all files are backed up (instead folder sync should have a separated queue independent from other backup operations and synchronization should occurs frequently... for example every 5 minutes or less, independently from the frequency of normal backup operations)

• Weird routing issue

  I'm having some weird internet problems on campus. I know it's something simple, but it's a case where I need another set of eyes. I think I can explain the problem best by posting a tracert: Tracing route to google.com [74.125.45.147] over a maximum of 30 hops: 1 3 ms 3 ms 3 ms 192.168.8.1 2 1 ms 1 ms 1 ms elissaemily-pc.york.edu [192.168.10.5] 3 2 ms 2 ms 2 ms rrcs-76-79-19-33.west.biz.rr.com [76.79.19.33] 4 31 ms 3 ms 2 ms ge-1-1-0.lnclne00-mx41.neb.rr.com [76.85.220.109] 5 20 ms 17 ms 17 ms ge-7-3-0.chcgill3-rtr1.kc.rr.com [76.85.220.137] 6 20 ms 20 ms 19 ms ae-5-0.cr0.chi30.tbone.rr.com [66.109.6.112] 7 19 ms 19 ms 24 ms ae-1-0.pr0.chi10.tbone.rr.com [66.109.6.155] 8 26 ms 24 ms 24 ms 74.125.48.109 9 23 ms 24 ms 21 ms 216.239.46.246 10 39 ms 39 ms 55 ms 209.85.242.215 11 39 ms 39 ms 39 ms 209.85.254.243 12 39 ms 40 ms 96 ms 209.85.253.145 13 39 ms 39 ms 39 ms yx-in-f147.1e100.net [74.125.45.147] Trace complete. Note the second entry in there. Not only is the host name a student's computer, but the ip address doesn't exist. Dhcp shows that host as having a different address and you can't ping any 192.168.10.5. Yet somehow it's routing packets for us (and not very well, either — things are slow right now). The basic network routing table looks like this: Destination Subnet Mask Gateway --------------------------------------- Default Route -- 10.1.1.5 (our firewall) 10.0.0.0 255.0.0.0 -- 192.168.8.0 255.255.252.0 --

• Browsing Playstation 3 from Ubuntu Box

  - by zfranciscus

  Hi, My Goal here is to be able to transfer files from my Ubuntu 10.04 box to my PS3 over a wireless network. My PS3 and my Ubuntu Box is on the same home network. These are some stuff that I tried: I can't see my PS 3 from 'Places ? Network' nor other computer that is running on windows. I am still puzzled by this fact. I have not tried ping-ing my PS3. I'll try that later today and post the result in the forum I install PS3MediaServer (http://code.google.com/p/ps3mediaserver/). Someone in the PS3 chat forum (http://www.ps3chat.com/playstation-3...lp-please.html) claims that it will enable your ubuntu box to browse PS3. So I downloaded PS3MediaServer, and ran the software. The status tab keep showing "Waiting ...". It seems that PS3MediaServer can't find my PS3. Some how I feel that 1 and 2 are related somehow.Perhaps that there is something wrong with my Ubuntu network settings that is preventing my ubuntu box from looking up other device on the network. I can go to the Internet fine, but I can't see other device on my network. Does anyone have any experience in this area. I would like to hear your experience and perhaps some solution. Any kind of hints or help will be greatly appreciated. Cheers

• Can I attach a VPN firewall to an existing network and have it manage VPN connections?

  - by jules

  I'm quite new to networking and am trying to set up my first VPN connection. The Situation: I have been contracted for some programming at a facility some distance from my location. I would like to be able to set up a simple VPN connection to their network so that I may make adjustments without significant travel. Their Current Network: Six devices (one I need to connect to) plugged into a basic router (Dlink). This router has an internet connection and a static ip address. My Hopeful (questionable) Proposal: I attach a VPN Firewall I happen to own (Netgear FVS318) as device number seven on the client network. I disable routing / DHCP in the Netgear. I forward the appropriate IPSec ports from the Dlink to the Netgear. I then create a VPN connection on my office Windows 7 machine to the remote network. The request is forwarded from the Dlink to the Netgear where the VPN connection is authenticated. I now have a remote-access connection from my office PC to the client's local network. The Question: Will this proposal work? If not, would another possibility be to attach a computer with a VPN server to the client network? Also, as a note: the client has requested I not replace their router or place mine in-between theirs and the internet :( Thanks very much!

• Task Scheduler Crashing MMC

  - by Valrok

  I've been getting errors whenever I try to run the task scheduler for Windows 2008 R2. Each time that I've tried running it, the task scheduler will crash and report the following: Problem signature: Problem Event Name: CLR20r3 Problem Signature 01: mmc.exe Problem Signature 02: 6.1.7600.16385 Problem Signature 03: 4a5bc808 Problem Signature 04: System.Windows.Forms Problem Signature 05: 2.0.0.0 Problem Signature 06: 50c29e85 Problem Signature 07: 151f Problem Signature 08: 18 Problem Signature 09: Exception OS Version: 6.1.7601.2.1.0.16.7 Locale ID: 1033 I've been looking online but so far I keep finding mixed results on what could be the fix for this and was wondering if anyone here has ever ran into this issue before. I read that this issue could be because of Security Update for Microsoft Windows (KB2449742) and that by uninstalling it I would be able to fix this issue, however I was not able to locate this anywhere in the server. Here's the link if interested Patch wise, everything is up to date. Also, I tried running hotfix KB2688730 to see if that would work after doing some research online, however the hotfix is not applicable to the computer. If anyone could provide some information on how to fix this and get the task scheduler running again it would be extremely helpful!

• Ubuntu raid 1 write errors

  I have an Ubuntu server set up with two SATA drives in a RAID 1 configuration with MDADM. The machine is used to record raw video, which involves a lot of writing to the disk.

• Printer deployment via Group Policy not working on a single system

  - by Aron Rotteveel

  One of my coworkers just got a new laptop running Windows 7 Pro x64. We use a GPO to deploy the printers to every system, but for some reason it is not working on this system. I have been breaking my head over this for the past 3 hours now without any result. The strange thing is that gpresult /H seems to indicate that the GPO did run. The hardware: Laptop: Windows 7 Professional x64 Print server: Windows Server 2008 x64 R1 HP Color LaserJet 2605dn HP LaserJet P2015 Driver packages on server: HP universal printer driver PCL5, both X86 as X64 Oddities and other info: GPO working flawlessly on every other system, including my own Windows 7 Ultimate X64 laptop gpresult /H shows the GPO being ran Windows Firewall completely disabled on the new laptop Below is the output for gpresult /H (in Dutch sadly, but I think you'll recognize it): Beleidsregels Windows-instellingen Printerverbindingen Pad Dominerend groepsbeleidsobject \\Server2008\HP Color LaserJet 2605dn Printers \\Server2008\HP LaserJet P2015 Printers Beheersjablonen Beleidsdefinities (ADMX-bestanden) opgehaald van de lokale computer. Configuratiescherm/Printers Beleid Instelling Dominerend groepsbeleidsobject Beperkingen van point-and-print Uitgeschakeld Printers Like I said, I have been trying to figure this out for the past few hours or so without any result, so you are my last hope.

• Ripping a home video VCD on Linux or Windows with VLC or otherwise

  - by user259774

  I have a VCD with 22 minutes of video on it. I would like to retain this footage and throw away the VCD. I can play the whole thing with VLC ("open disc - vcd - /dev/sr0 - play"): all 22 minutes of the main track. I don't believe there's any other content aside from the main track. I can seek to anywhere I want to within the 22 minute track. If I mount /dev/sr0 /media/vcd and then try to copy the only file from the MPEGAV folder, I get an I/O error, with an empty destination file. VLC has a "convert" option in addition to "play". When I use this I actually get a good OGG file back, after it runs through the video in painful real-time. I guess it dubs it frame-by-frame. But the file is only 10 minutes long, leaving 12 minutes off of the track. Handbrake doesn't detect it's track titles, unfortunately. I don't know if I should start getting involved with GNU ddrescue or if it's because VCDs somehow encode their data sectors differently. Anyway, I'm in way over my head and if anyone knows how I could get that video track off the thing, feel free to share! Edit: I should note that I also have access to a Windows computer
