• Nvidia 9800GT randomly prevents computer from booting

  - by Blender

  My computer has been running Windows and Linux perfectly fine with my 9800GT for the past year or so, but today it refused to boot. When I press the power button, this is what happens: Power button flashes once. Fans whir. Graphics card makes clicking noise. Computer reboots. Go back to 1. The cycle just keeps going, and I have to yank the cord to make the computer stop. After about 30 attempts at booting it, the computer powers on and everything works. I'm pretty sure that the graphics card isn't malfunctioning, as I've been GPU computing on it for a while now without any hiccups. But the strange thing is, the computer boots perfectly fine in only 5 boots if I remove the card. The computer is a HP Pavilion a6028x Desktop PC: Processor: AMD Athlon 64 X2 (W) 4600+ 2.4 GHz (AM2 socket) Motherboard: ECS MCP61PM-HM (Nettle 1) RAM: 3GB DDR2 (two different brands) More specs here Does anybody know what could be the problem? Any help or information would be greatly appreciated!

• Reverse NAT Setup for Hyper-V on Win 2008 R2

  - by sukru

  I'm trying to setup a Linux server behind a Windows Hyper-V host that will help supply some of the services (SSH, HTTPS, etc). However getting RRAS configured for reverse NAT (port forwarding) turned out to be a non trivial task. As a staring point, I tried forwarding port 22 (SSH) to the virtual machine. The virtual machine is on a public interface (i.e.: it also has a visible IP on the same network as the host). On RRAS management console I tried to add a rule, by adding "Local Area Connection" to NAT pool (Public Interface - Enable Nat), and an incoming rule for port 22 - :22. I also tried with the same port enabled on Windows Firewall (and not). The NAT management page tells there are "1 mappings" and "30+ Outbound packets transleted". However all other counters (Inbound packets translated, and respective rejected ones) are always zero. (I'm trying to access the server from an external machine). I can directly access the service if I give the VM's public IP, but not the host's one. Is there a way to enable this on RRAS?

• How to configure SVN server for my own project

  - by user1729952

  I work with a team on an Android project using Eclipse IDE, we need to use a version control and we need to access the repo remotely, I have no experience using or installing servers, a little experience using SVN on Windows, but I still have problems connecting to it remotely. I need to use no-ip.com to change my IP, however; I failed to make VisualSVN server to work with no-ip. What options do I have? The best thing is to get it work with Windows if not, I have another computer that is running Ubuntu 12.4.1, I have installed apache2svn on it trying to get it work, the svn is installed, I went through tutorials to configure accessing protocols, but I can't figure out how to access it remotely from another computer? Can someone tell me the steps I need to get this job done and I can do my search for each step? (Please explain each step as some keywords or phrases I may not be familiar with) EDIT: Also worth noting, that my company has a website hosted on a remote server, can we use it as a repo? and how? It's running Linux

• How do I tunnel an HTTPS proxy through a virtual machine (VMWare)

  - by Kyle

  I have a personal setup at home using VMWare Workstation. I also have a set of Virtual Private Machines that run Squid, and therefore provide me HTTPS proxy tunnels. Using Proxifier, I can tunnel all traffic for given applications through these tunnels. However, I also have a few virtual machines for dev/staging/experimentation/etc. I generally just use NAT to provide Internet access to the machines, and if I need to use these proxies, I can just setup Proxifier (or a Linux equivalent) to pipe the traffic through them. No problem. But... I got to thinking: Wouldn't it be great if I could assign these proxy tunnels to a virtual machine, so that when I start up the VM, it has instant-on access through the tunnel and not my local connection? (EDIT: Of course, it would USE my local connection, but it would tunnel traffic through the proxy.) To be more clear: I want a solution that binds the proxy to a VM, so that when I start the VM, I don't have to use a proxy client to connect to the tunnel - I am already piping all traffic from that VM through that proxy. I did a bit of searching, and the closest thing I could find was this: How to route public static IP to a virtual machine on a vmware ESXi host? Which wasn't all that applicable. The proxies are protected by user/pass but do not filter by IP. Again, they are HTTPS proxies setup through Squid. Any ideas on how to make this happen? Thanks a ton.

• Which free RDBMS is best for small in-house development?

  - by Nic Waller

  I am the sole sysadmin for a small firm of about 50 people, and I have been asked to develop an in-house application for tracking job completion and providing reports based on that data. I'm planning on building it as a web application. I have roughly equal experience developing for MySQL, PostgreSQL, and MSSQL. We are primarily a Windows-based shop, but I'm fairly comfortable with both Windows and Linux system administration. These are my two biggest concerns: Ease of managability. I don't expect to be maintaining this database forever. For the sake of the person that eventually has to take over for me, which database has the lowest barrier to entry? Data integrity. This means transaction-safe, robust storage, and easy backup/recovery. Even better if the database can be easily replicated. There is not a lot of budget for this project, so I am restricted to working with one of the free database systems mentioned above. What would you choose?

• Could I have destroyed Partitioning-Scheme/Filesystem of HDDs with External Harddrive Case with builtin Raid-Controller?

  - by th3m3s

  I had just recently bought a Fantec QB-35US3R to have a nice box on my desk to make some backups to. Along with the HDD-Bay I had ordered some 4TB HDDs to let them run in Raid 5, which is handled by the hardware RAID controller of the Fantec HDD-Bay. The QB-35US3R arrived a few days before the hard drives, so I got impatient and had the idea to put three old 1TB disks in the Fantec device, just to test it... Long story short: I made a backup of the most important data on these three disks before they broke. I had set the configuration scheme to RAID 3 at the Fantec device. It seems, that the Fantec RAID controller has "somehow" destroyed the partitioning scheme or the file system, because when put into a HDD docking station, they get recognized by the OS (Ubuntu/Linux) but are not mountable anymore. I tried to recover the data from one HDD via gParted (parted), which ran some hours without success. Here I stopped, before trying other tools, cos I read that the longer a hard drive is running after a the partitioning got destroyed, the worse it gets. What could the HDD-Bay probably have done to my lovely hard drive disks? Is there some routine a RAID controller is executing, when it wants to create a RAID system? Like erasing the partition table (seems not plausible to me.) or writing some information to every hard drive in the RAID (seems more likely to me.)? Is there a chance to recover the data from these HDDs, or is the change a RAID controller makes so significant, that no software is of help?

• How do I re-configure grub options

  - by Ash

  I've searched this topic and I can't find an article with a plausable solution, to my problem. I installed windows 7 first, with 100gb of disk space. I created the necessary partitions via windows. Then I installed Ubuntu 12.04 on the remaining 400gb of disk space. During the Ubuntu installation I installed the ubuntu boot loader on /dev/sda3 which Windows (as expected never granted me the option pre-boot for which OS I wanted to boot). So I re-installed Ubuntu on that /dev/sda3 partition, overriding the windows 7 loader. Now when I boot windows 7, it runs GNU Grub, so like an infinite loop. How can I reconfigure grub to say: /dev/sda is the bootloader. /dev/sda2 is Windows. /dev/sda3 is Ubuntu. Re-installing windows and my partitions isn't an option, purchasing software for windows isn't an option (theres a reason I use linux, it's not because it's free, because you don't have to install lots of shit to get stuff working, and over-all it's a robust OS).

• Data recovery on working hard drive

  - by emgee

  So I have a 5 bay hot swap SATA enclosure that's connected to a Silicon Image-based SATA adapter in a computer. It's running XP Pro. There are two 1.5TB hard drives in slots 1 and 2 respectively, set up using RAID 1 using the the Silicon Image utility. There are also two 1TB drives in bays 3 and 4, also set to RAID 1 the same way. The partitions for both RAID arrays are Dynamic partitions. A few days back, there was a bare hard drive that needed some files copied off of, so it was popped it in bay 5, that bay to pass-through, and the copied data off of it. Later, I noticed that my 1.5TB drives no longer showed up in windows. In the Silicon Image utility, the drives showed up fine, no error. However, in Device Manager, it shows the RAID 1 array as uninitialized. It shows up as the right size, etc., but nothing else. There's no sign of anything wrong with either drive, so I'm not sure what happened exactly. I'm not the only one who has access to that computer, so it is possible there is something else done to it that I don't know of. There's quite a lot of data on it still, and if at all possible, I'd prefer to not send it to Ontrack. Does anyone know of software that would restore the partitions, keeping in mind that it's a Windows LDM partition? I have access to a variety of Operating Systems, so something that would work on Mac, Windows or Linux would be acceptable. The programs I usually use are not compatible with LDM.

• Summer daylight time not changing on some active directory domain clients.

  - by Nick Gorbikoff

  We just had a summer daylight change in US. and pc's on my network are behaving strange, some of them change time and some didn't. My network: 2 locations both in Midwest, same time zone. Location 1: 120 pcs (windows xp & windows 200) , with 1 Active Direcotry Domain Controller on Windows 2003 Standard. A couple of windows 2000 servers (they up to date) the rest of the servers are Xen or Debian machines (all up to date) , Second location connected through OpenVPN link all pc's are running fine - but they are all connecting to our AD domain controller. Locaiton 2: 10 pcs, and a shared LAN NAS. Both of the routers/firewalls in both locations are pFsense boxes with ntp service running - but it's up to date. Tried all the usual suspects: I have all the latest updates installed restarted them domain controller is running fine most computers are running fine I have only one domain controller on my network also my firewall serves as ntp server (pfsense) but it's up to date. all of the linux machines are fine since they are querying firewall / router for the time. about 1/3 of my pcs are 1 hour behind. If I change them manually they just change back ( the way domain pc's are supposed to). I've tried everything but I can't think of anything else to try.

• Permissions for Multiple User VPS

  - by adnymarc

  I have a Linode VPS server that I have recently setup and am migrating to from Mediatemple, where I have a VPS managed by Plesk. I dislike the Plesk interface and the mess it makes of a lot of things, but appreciated its ability to allow multiple people access to different domains on a server. I have most everything setup the way I would like it, but am having issues with permissions for my domain directories. I am running Ubuntu 8.04 LTS and Apache 2 as my web server. I have domains successfully located in /var/www/vhosts/domainname.com but have to modify files as root in order to add/change files for the domains. I would like to setup access with the following criteria: Each domain can have a user assigned to it (and allow for the same user to manage multiple domains - could even create symlinks in their home folder to their domains) Certain users will have shell access and may be chrooted to the domain directory they control FTP needs to be setup and able to correctly access the domains so that content editors for each domain can upload/download without permissions issues I am relatively new to linux sysadmin and have searched for a good guide to help solve these issues but haven't been able to find one yet. Thanks in advance for your help.

• Methods and practices for managing a network that has no internet connection

  - by FaultyJuggler

  Originally asked in Super User but realized this belongs here. Long story short, I am setting up a network with 32 servers of varying specs that will be used for testing and development. We will be using RedHat Linux, we also do not have a router as of yet and were looking into making one of the servers act as our router/DHCP etc. The small cluster will be on an isolated network with no internet. I can use external harddrives and discs to transfer anything from external sources into machines on the network, so this isn't a locked down secure network, it just won't have a direct connection to the outside world. I've worked on such setups before, but always long after they were setup. So I'm reaching out to see what everyone knows as far as how groups have handled initial setup and maintenance of such a situation. What is the best way to get them all configured and up to date? What are the best ways to automate updates, network wide installs, etc. With the only given that I have large multi-terabyte external hard drives that would be used to drop whatever files are needed onto a central server, how do i then distribute those files and install their contents? I've done perl scripting, some teammates have played with puppet, so we aren't completely in the dark, I just wanted to avoid reinventing the wheel since this is a common challenge.

• Cause of laptop only booting once every 3-10 times

  - by user16441

  My 3-year old Asus EEE laptop has been working flawlessly in the past, but in the last week it has started behaving oddly. When I boot, one of the following happens: Screen remains totally black. Absolutely nothing comes up. I need to retry booting. (Happens 70% of the time). Laptop starts regular boot. However, somewhere during the boot process it goes black and I need to retry (20% of the time). Screen turning black is more likely when I move the laptop around during boot. Laptop boots properly. Once booted, all is fine. But I'm afraid to turn it off and have been keeping the laptop running till the night. Additional details: All normal lights light up when I boot; whichever of the scenarios goes down. There are no odd sounds or beeps, whichever of the scenarios goes down. I thought it might be the SSD drive that is dying, but it does not use SMART and it appears difficult to troubleshoot. I tried booting with and without the battery, but the scenarios are identical. Before completely investigating the hard drive, I'd like to hear opinions regarding the cause of this problem. Is this most likely the hard drive, or could there be another cause for these symptoms? Using Arch Linux.

• Allocating More Than 4 GB Of Memory

  - by TPatti

  I am facing an issue with memory allocation. I have: Host OS: Microsoft Windows XP - Professional x64 Edition - Version 2003 - Service Pack 2. Host Physical Memory: 8 GB Guest OS: Red Hat Enterprise Linux WS release 4 (Nahant Update 5). I am not sure if it is 32 or 64 bits. The lsb_release -a command says that argument LSB Version: core-3.0-ia32, so I guess that would be 32 bits... VMware Player Version: 2.5.2 build-156735 I would like that VMware Player could allocate more that 4 GB, but when I go to the setting, it only lists 4 GB. If I choose the "About" option, it actually says that I have 8 GB installed in the host machine. This VMware image created by someone else and provided to me, apparently done with VMware Workstation 5. Why can't I allocate 8 GB? Where is the problem? In the WMware Player Version, Guest OS or Host OS? How can I solve this? I understand that for this version of player there isn't one version for 32 and another for 64 bits.

• Revoke directory access for a particular user in Solaris

  - by permissiontomars

  I have a need to allow directory access to a particular user on my file system. I want this user to be unable to access any other directory in my file system (initially anyway. It may need access to some directories later). For example: I have a directory called /opt/mydir. - I want my dedicated user to only be able to access this directory, and nothing else. - I want all other users to be able to access this directory as normal. I'm new to Linux and its permissions. I've read a fair bit of background material but I'm a little confused. Is there anyway to revoke permissions to /opt/mydir for a single dedicated user? A possible flawed method would be to only allow access to /opt/mydir and exclude every other user. This won't work because I want all other users to work as normal; accessing the directory. I'm working on Solaris 10. Any suggestions are appreciated.

• Allow more websocket connections

  - by Switz

  I want to load balance my node.js (DerbyJS to be specific) application on a basic Linode (512MB ram). It can probably take more than one process running at once. The querys/database does not concern me as I'm not doing anything intensive. The problem at the moment is that it can only handle up to ~40 websocket connections at once. I would love if I could get that number in the few hundred+ range. I anticipate a lot of traffic on launch due to the fact that it's a highly niche community with an engaged audience, but after it should be fine with just ~20-40 connections at once, which it handles perfectly as of now. I don't mind spending a bit of money for a week or two worth of running, but I also don't want to switch production environments. How can I test the process to see how many instances I am able to run on the box? Will increasing the number of processes increase the amount of websockets I can handle, or is that a limitation of the server's network? I have an old Macbook Pro running Linux sitting next to me that has 2GB ram and a 2.8 Dual Core Processor. Could I use this to handle some of the extra load? I could probably load balance with nginx to its IP. I'm on a FiOS home network. If you have any suggestions, I'd really appreciate it. Thanks

• Help with Backup Scheme for B.E 12.5

  - by Jemartin

  I'm in process of implementing a new backup scheme. I would say that I'm kind of new to it. So here my question. I'm currently using Backup Exec 12.5 on Windows Server 2008 w/Hyper-V, and IBM Adic Scalar 24. I currently backup our mail server, SQL DB, Board Server Linux Red Hat, Ftp, etc. To a Near-line which is local on our SAN I have the daily's go there as well as full. I would like to start weekly full to tape on a Saturday it takes about 2-3 days to complete the entire full to tape due to backing up from our Co-Lo as well. I have read up on the Father/son rotation but here's my issue with that I dont use tapes everyday only on the weekly full to tape will I be using them. So if there is 4 weeks in a month would I rotate in this order ( Month June WK1 =7tapes , June WK2=7 tapes, June WK3=7tapes June Wk4=7tapes with WK4 being the last tape for the month of June I would use that as a Month tape. For the month of July Wk1= June's WK1 tapes, July WK2= June's WK2 tapes July WK4 = Junes Wk4 tape for a month or would I use a set of new tapes for the last week in July. All tapes are being taking off site as well.

• What are the ways to build a failover cluster?

  - by light

  I have a task where I need to build a failover cluster in two cases: first with servers on Red Hat Enterprise 5.1 and second with SUSE Linux Enterprise 11 SP1. Both cases have SAN. I know there are many ways to build failover cluster, but I can’t find out more, so I need next: The ways to build it? I know only virtualization. Any good book or resource to broad my mind? I’ll be glad to hear any suggestion. Thanks! EDIT #1: failover of servers with bussiness application on it. EDIT #2: will be great to hear summary about solutions with SLES servers? EDIT #3: So if I understand correctly, in my cases the main ways are to use internal solutions or virtualization. So now I have additional questions: Does manufacturer of blades provide some solution? For example HP or IBM. (Without virtualization) Do I need additional server to control "heartbeat" between main and redundant servers? (Virtualization) For example I have several physical servers with VMs. Do I need additional server to control availability of VMs and to move VMs to another physical server in the case their physical server failure? Sorry for my poor English. EDIT #4: Failover of VM or OS on physical server. In both cases will be used SAN , it's not specified, but I think with file system image on it. I started to think that my question is stupid and I need to remake it.

• Ubuntu 9.10 won't reboot after replacing a failed drive

  - by user149041

  Hello Serverfault community. I hope someone can shed light on a peculiar problem I am having with an Ubuntu 9.10 server install. I am not a Linux expert but have the responsibility of fixing the box if something goes wrong. DOH! I have Ubuntu 9.10 server installed on on a desktop platform: Compaq Presario SR5027CL. There are two 1TB SATA drives configured in a RAID 1 array; I use the box as an email backup server for a small group of users. Last week one of the drives failed and was replaced with a new drive of the same type. The problem I have been having is getting the box to reboot after a restart or a shutdown halt. The OS and the RAID 1 array are on the same drives that make up the RAID 1 array. The replacement drive (sda) was added to the box and the partitions were created to match the existing good drive (sdb). The array is made up of sda1 and sdb1. I found an interesting point while checking the BIOS settings: there is a "HDD Boot Group Priority" section, and the new drive was selected as the "1. 3rd master"; the server wouldn't boot configured like that, but when I set the old drive to be "1. 4th master", the box will reboot. I'm checking some more things, but I would certainly appreciate any useful information. Thanks in advance.

• Private subnet for VM server host-only network

  - by Derek Pressnall

  At my current job, we distribute a product based on a Linux server with multiple VMs defined (using KVM / libvirt). We are planning to expose limited ports to the customer's network, and use iptables to direct inbound traffic to the appropriate internal VM. My question: is there a class of private subnets that I can use for the internal host-only network that is least likely to conflict with a client IP subnet? Specifically, if I choose a /24 out of any of the RFC-1918 defined private subnets (such as 192.168.x.x), there is a chance of conflicting with a customer-used range. I noticed that several current VM implementations default to 192.168.122.x -- is this due to an RFC that I'm not familiar with, and therefore this is a safe range to use (that most network admins would avoid)? Or did the various VM vendors just pick that range randomly? I guess I'm looking for an IP range that is more private than the existing private (RFC1918) addresses. The only other thought I had was to use one of the "Test Net" IP ranges reserved for documentation purposes (RFC 5737). Note, that I'm not worried about a customer's network blocking these IPs, as this is only internal to our server (packets get NATted before leaving the box). However this does seem more unorthodox than just sticking with the default 192.168.122.x/24 subnet.

• How to minimize the risk of employees spreading critical information? [closed]

  - by Industrial

  What's common sense when it comes to minimising the risk of employees spreading critical information to rivalling companies? As of today, it's clear that not even the US government and military can be sure that their data stays safely within their doors. Thereby I understand that my question probably instead should be written as "What is common sense to make it harder for employees to spread business critical information?" If anyone would want to spread information, they will find a way. That's the way life work and always has. If we make the scenario a bit more realistic by narrowing our workforce by assuming we only have regular John Does onboard and not Linux-loving sysadmins , what should be good precautions to at least make it harder for the employees to send business-critical information to the competition? As far as I can tell, there's a few obvious solutions that clearly has both pros and cons: Block services such as Dropbox and similar, preventing anyone to send gigabytes of data through the wire. Ensure that only files below a set size can be sent as email (?) Setup VLANs between departments to make it harder for kleptomaniacs and curious people to snoop around. Plug all removable media units - CD/DVD, Floppy drives and USB Make sure that no configurations to hardware can be made (?) Monitor network traffic for non-linear events (how?) What is realistic to do in a real world? How does big companies handle this? Sure, we can take the former employer to court and sue, but by then the damage has already been caused... Thanks a lot

• Qt vs WPF/.NET

  - by aaronc

  My company is trying to make the decision between using Qt/C++ for our GUI framework or migrating to .NET and using WPF. We have up to this point been using MFC. It seems that .NET/WPF is technically the most advanced and feature-rich platform. I do, however, have several concerns. These include: Platform support Framework longevity (i.e. future-proofing) Performance and overhead For this application we are willing to sacrifice support for Windows 2000, Macs, and Linux. But, the issue is more related to Microsoft's commitment to the framework and their extant platforms. It seems like Microsoft has a bad habit of coming up with something new, hyping it for a few years, and then relegating it to the waste-bin essentially abandoning the developers who chose it. First it was MFC and VB6, then Windows Forms, and now there's WPF. Also with .NET, versions of Windows were progressively nicked off the support list. Looks like WPF could be here to stay for a while, but since its not open source its really in Microsoft's hands. I'm also concerned about the overhead and performance of WPF since some of our applications involve processing large amounts of information and doing real-time data capture. Qt seems like a really good option, but it doesn't have all the features of WPF/.NET couldn't use languages like C#. Basically, what does the community think about Microsoft's commitment to WPF compared with previous frameworks? Are the performance considerations significant enough to avoid using it for a realtime app? And, how significant are the benefits of WPF/.NET in terms of productivity and features compared to Qt?

• Xdebug configuration with PHP fastcgi and eclipse?

  - by mac

  I have been using eclipse-pdt in conjunction with xdebug and apache without problems, for over one year. Things worked flawlessly and I could do all the interactive debugging I wanted from within eclipse (using my own machine as a server). Now I switched from apache to nginx (and therefore PHP runs now not as an Apache service but as fast-cgi) and I can't find a way to configure eclipse to work nicely with xdebug. I am neither sure if the problem is with xdebug or with eclipse (or both) to be sure. In the eclipse configuration I already changed the reference to the PHP configuration file to /etc/php5/cli/php.ini. Attempts with php.ini version 1 With the following php.ini file zend_extension=/usr/lib/php5/20060613/xdebug.so I see that xdebug is working (for example if I do a var_dump() I get the xdebug version of it, not the plain PHP one) I can't have the interactive debugging from eclipse: the browser opens up and loads the page completely with the typical URL containing ...?XDEBUG_SESSION_START=ECLIPSE_DBGP&KEY=..., but the program execution does not stop at breakpoints In the bottom-right corner of eclipse I see a suspicious message: *"Launching =put_the_name_of_my_project_here=: 57%"* that alternates with the "refreshing workspace" one. Attempts with php.ini version 2 If I use this other version of the file (which is what it worked until I switched to nginx): zend_extension=/usr/lib/php5/20060613/xdebug.so xdebug.remote_enable=On xdebug.remote_autostart=On xdebug.remote_handler=dbgp xdebug.remote_host=localhost xdebug.remote_port=9000 xdebug.remote_mode=req I can't access any page of my sites at all. Any help or suggestion appreciated, thank you in advance for your time!

• How can I discover zeroconf (Bonjour) services on Android? I'm having trouble with jmDNS.

  - by Peter Kirn

  I'm working with a Droid / Android 2.0.1 and encountering an issue apparently many people have: I'm unable to discover services using the one pure-Java zeroconf library I know of, jmDNS. (Apple's Bonjour, while it works on Linux and Windows Java, I believe would be harder to port to Android because of reliance on native code.) I can create services, but not discover them. I'm trying to make sense of what's going on. There is an ongoing issue report here; related to multicast and IPv6, but seems to be throwing users of jmDNS, too: http://code.google.com/p/android/issues/detail?id=2323 Any idea why this person might be having success? See comment 22 in the bug report. (I'm new to SO, so can't post more than one URL.) I have tested their code, but without any luck. Has anyone successfully accomplished zeroconf service discovery on Android, using jmDNS or another library? Is it possible my discovery issue is related to the IPv6 multicast problem?
