  • 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?

  • Mounting a VirtualBox shared folder on boot with fstab in OpenSuse 11.3

    - by ccook
    I have followed the steps found here, however, the share is not mounted on boot. The share will mount if i run 'mount -a' after booting. Why would the share not mount on boot? 1 - Set up a Virtual Machine and install OpenSUSE 11.2 2 - Create a shared folder on host (HostFolder) 3 - Setup the shared folder in Virtualbox Via the Virtual Machine details or via Devices Shared Folders... 4 - Install dependencies for running the Virtualbox installer You need to install the right development kernelpackage for your machinetype (use 'zypper search -i kernel' to see what's installed) sudo zypper install make gcc kernel-source kernel-hosttype/default-devel 5 - Run the Virtual Machine and go to Devices Guest Additions This mounts an iso image in your OpenSUSE guest. 6 - Open a root terminal and run cd /usr/src/linux make oldconfig && make prepare && make scripts && make dep cp ../linux-obj/$HOSTTYPE/default/Module.symvers . make prepare A commenter on previously mentioned thread says this step is unnecessary but it doesn't work without on my system. I suggest trying step 7 first and returning to step 6 if that fails. * 7 - Run ./VirtualboxLinux yourhosttype .run from the mounted iso image. 8 - Create shared folder in OpenSUSE (GuestFolder) 9 - Test with sudo mount -t vboxsf HostFolder /home/user/GuestFolder It works? Great! Let's set up the system so it automounts for your regular useraccount instead of root-only access. 10 - Add this line to /etc/fstab HostFolder /home/user/GuestFolder vboxsf defaults,uid=1000,gid=1000 0 0 11 - It works for me but if it still doesn't automount after a reboot; sudo mount -a

  • Ubuntu with KVM guest VM and broken bridges

    - by MadPsy
    I have an Ubuntu box with a KVM guest VM running. They use bridging so the guest VM attaches to the physical network of its host. The guest VM has 2 NICs in 2 different bridges. First NIC of the VM is tap5 and is in bridge br0 br0 8000.46720f5c572e no eth0.500 tap5 Second NIC of the VM is tap2 and is in bridge br100 br100 8000.76ad2fc96661 no eth0.100 eth0.101 eth0.103 eth0.104 eth0.105 tap2 On the host, br0 has an IP and br100 does not 21: br0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP link/ether 46:72:0f:5c:57:2e brd ff:ff:ff:ff:ff:ff inet 192.168.100.4/24 brd 192.168.10.255 scope global br0 inet6 fe80::d6ae:52ff:febe:777/64 scope link valid_lft forever preferred_lft forever On the guest, its eth0 and eth1 interfaces both have IP addresses 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:3e:61:fb:7a:da brd ff:ff:ff:ff:ff:ff inet 192.168.100.6/24 brd 192.168.100.255 scope global eth0 inet6 fe80::23e:61ff:fefb:7ada/64 scope link valid_lft forever preferred_lft forever 3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:3e:61:fb:7a:ea brd ff:ff:ff:ff:ff:ff inet 172.16.50.129/25 brd 172.16.50.255 scope global eth1 inet6 fe80::23e:61ff:fefb:7aea/64 scope link valid_lft forever preferred_lft forever On the guest VM, a tcpdump of its eth1 interface (tap2) shows traffic from its eth0 interface (tap5), as if the 2 bridges are themselves bridged. This means any interface on br100 is now bridged across to br0 - which is completely broken. root@chillispot:~# tcpdump -c 1 -n -v -i eth1 net 192.168.100.0/24 tcpdump: listening on eth1, link-type EN10MB (Ethernet), capture size 65535 bytes 16:31:24.175583 IP (tos 0x0, ttl 64, id 48054, offset 0, flags [DF], proto TCP (6), length 148) 192.168.100.6.22 > 192.168.100.4.59505: Flags [P.], cksum 0x6c2b (correct), seq 1056321648:1056321744, ack 398642983, win 1700, options [nop,nop,TS val 197473436 ecr 200655363], length 96 What could be bridging the 2 bridges, except the guest VM (which is a stock Ubuntu install)? I am at a complete loss! Thanks.

  • Ubuntu Pound Reverse Proxy Load Balancing Based off active server load?

    - by Andrew
    I have Pound installed on a loadbalancer. It seems to work okay, except that it randomly assigns the backend server to forward the request to. I've put 1 backend machine under so much load that it went into using swap, and I can't even ssh into it to test this scenareo. I would like the loadbalancer to realize that the machine is overloaded, and send it to a different backend machine. However it doesn't. I've read the man page and it seems like the directive "DynScale 1" is what would monitor this, but it still redirects to the overloaded server. I've also put in "HAport 22" to the backend figuring since I can't ssh in, neither could the loadbalancer and it would consider the backend server dead until it gets rid of the load and responds, but that didn't help either. If anyone could help with this, I'd appreciate it. My current config is below. ###################################################################### ## global options: User "www-data" Group "www-data" #RootJail "/chroot/pound" ## Logging: (goes to syslog by default) ## 0 no logging ## 1 normal ## 2 extended ## 3 Apache-style (common log format) LogLevel 3 ## check backend every X secs: Alive 5 DynScale 1 Client 1200 TimeOut 1500 # poundctl control socket Control "/var/run/pound/poundctl.socket" ###################################################################### ## listen, redirect and ... to: ## redirect all requests on port 80 to SSL ListenHTTP Address 192.168.1.XX Port 80 Service Redirect "https://xxx.com/" End End ListenHTTPS Address 192.168.1.XX Port 443 Cert "/files/www.xxx.com.pem" Service BackEnd Address 192.168.1.1 Port 80 HAport 22 End BackEnd Address 192.168.1.2 Port 80 HAport 22 End End End

  • SSH multi-hop connections with netcat mode proxy

    - by aef
    Since OpenSSH 5.4 there is a new feature called natcat mode, which allows you to bind STDIN and STDOUT of local SSH client to a TCP port accessible through the remote SSH server. This mode is enabled by simply calling ssh -W [HOST]:[PORT] Theoretically this should be ideal for use in the ProxyCommand setting in per-host SSH configurations, which was previously often used with the nc (netcat) command. ProxyCommand allows you to configure a machine as proxy between you local machine and the target SSH server, for example if the target SSH server is hidden behind a firewall. The problem now is, that instead of working, it throws a cryptic error message in my face: Bad packet length 1397966893. Disconnecting: Packet corrupt Here is an excerpt from my ~/.ssh/config: Host * Protocol 2 ControlMaster auto ControlPath ~/.ssh/cm_socket/%r@%h:%p ControlPersist 4h Host proxy-host proxy-host.my-domain.tld HostName proxy-host.my-domain.tld ForwardAgent yes Host target-server target-server.my-domain.tld HostName target-server.my-domain.tld ProxyCommand ssh -W %h:%p proxy-host ForwardAgent yes As you can see here, I'm using the ControlMaster feature so I don't have to open more than one SSH connection per-host. The client machine I tested this with is an Ubuntu 11.10 (x86_64) and both proxy-host and target-server are Debian Wheezy Beta 3 (x86_64) machines. The error happens when I call ssh target-server. When I call it with the -v flag, here is what I get additionally: OpenSSH_5.8p1 Debian-7ubuntu1, OpenSSL 1.0.0e 6 Sep 2011 debug1: Reading configuration data /home/aef/.ssh/config debug1: Applying options for * debug1: Applying options for target-server.my-domain.tld debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug1: auto-mux: Trying existing master debug1: Control socket "/home/aef/.ssh/cm_socket/[email protected]:22" does not exist debug1: Executing proxy command: exec ssh -W target-server.my-domain.tld:22 proxy-host.my-domain.tld debug1: identity file /home/aef/.ssh/id_rsa type -1 debug1: identity file /home/aef/.ssh/id_rsa-cert type -1 debug1: identity file /home/aef/.ssh/id_dsa type -1 debug1: identity file /home/aef/.ssh/id_dsa-cert type -1 debug1: identity file /home/aef/.ssh/id_ecdsa type -1 debug1: identity file /home/aef/.ssh/id_ecdsa-cert type -1 debug1: permanently_drop_suid: 1000 debug1: Remote protocol version 2.0, remote software version OpenSSH_6.0p1 Debian-3 debug1: match: OpenSSH_6.0p1 Debian-3 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.8p1 Debian-7ubuntu1 debug1: SSH2_MSG_KEXINIT sent Bad packet length 1397966893.

  • Is It Possible to Change Default Windows Idle Time for Task Scheduler?

    - by alharaka
    From the official Microsoft docs: Detecting the Idle State The Task Scheduler service will verify that the computer is in an idle state every 15 minutes. The computer is considered idle if all the processors and all the disks were idle for more than 90% of the past 15 minutes and if there is no keyboard or mouse input during this period of time. Besides, any presentation type application that sets the ES_DISPLAY_REQUIRED flag will make Task Scheduler to not consider the system as being idle. In Windows 7, Task Scheduler considers a processor as idle even when low priority threads (thread priority < normal) execute. Is there any way to change the time to less than 15 minutes minutes? Am I assuming this hard-coded and impossible? My Google-fu has eluded me so far and I found nothing, but wanted to check here before giving up.

  • OS X Terminal lines don't go into scrollback

    - by Steve Madsen
    I have a problem that crops up when using Mac OS X's Terminal (TERM=xterm): sometimes it gets itself into a state where lines that scroll off the top are not added to the scrollback buffer. I'm not using screen or similar; this is a plain bash shell inside a Terminal tab. It doesn't do this immediately after opening a new tab. I believe it is a side-effect of something I've run in the problem tab. My guess is that it has something to do with the xterm emulation, possibly the scroll region. What hasn't worked: Soft and hard reset via the Shell menu Running reset in the tab Is there a reliable way to reset Terminal and/or the xterm state? Can anyone provide a explanation for what's happening, even if the only fix is to close the tab and open a new one?

  • Setting up self signed cert and CA [plesk / linux]

    - by microchasm
    I'm about ready to give up and do a clean wipe of this machine and start over with ISPConfig or some other variant. I installed Plesk on this machine to help with some of the handiwork. It is the free version (single domain); I don't need it for much. It's nice, though, to use to set up db's email, etc. Anyway, I would like to set it up as a CA (which I can add to users' trusted root servers to alleviate those warnings). It seems like Plesk does all it can to obfuscate where things are. Despite trying to find the conf files, and crt/pem/key etc. I am (5 hours later) now left with a machine that won't even get to the ssl page. The browser will sit there, until a 'connection reset' error comes up. In error_log, I get messages saying CN doesn't match server name -- which it does. ssl_error_log: [Thu May 13 16:02:14 2010] [warn] RSA server certificate is a CA certificate (BasicConstraints: CA == TRUE !?) [Thu May 13 16:12:19 2010] [warn] RSA server certificate is a CA certificate (BasicConstraints: CA == TRUE !?) not very helpful. If anyone has any experience, and/or recommendations (including other software), I'd be much obliged. NB RHEL5; 1 domain, 3 subdomains; everything local only. Thanks.

  • How can I install my installed linux on another hardware too?

    - by donamir
    Hi. It's my state: I installed some apps on a linux server(ubuntu). Apps stack are development tools: -some of Atlassian product -SVN, USVN -Maven, Artifactory -Tomcat & ... My problem: I want to create a bootable dvd to be able to restore same state(OS, configuration and apps) on another hardware(server). Some notes: I prefer ubuntu but my linux can be a different distributions if needed. w I prefer final result (bootable dvd) be simple and easy to use as installing a linux(ubuntu). I prefer a bootable DVD but if it's not possible, any other solution like partial backup/package even if needed to install first OS and then apply the package/backup/... can be good. Finally: Thanks in advance.

  • How to configure a trusted connection between IIS 7 and SQL Server 2005?

    - by user1180652
    How do configure a trusted connection between IIS 7 and SQL Server 2005? My webapp was working fine with Windows Authentication enabled in IIS. Now, in order to solve a problem, we need to use a trusted connection. Unfortunately, enabling the trusted connection in the web.config broke the webapp. Oddly enough, when I run this application with trusted connection from my local dev machine (using the Cassini web server) IIS (Windows Server 2008) is running on one machine. The database (SQL Server 2005 but could migrate to 2008) is running on another machine. We are on a Windows domain running AD. All traffic is within our own firewall - no public access. Beyond that, I can't provide much info but I can find it. We're very "compartmentalized" (we have server people, security people, oracle people, SQL Server people, etc.) Thanks! Update 02/14/2012 0902: The webapp is now functional (app no longer broken) but the main issue is still unresolved. Now I have the app's application pool running as a domain account with permissions on the SQL Server box and IIS box. We were using this account to run the application but, and here's the problem, we need to log the real user name that made a change. When using the service account, the name of that service account appeared in the audit tables, making the auditing quite useless. So, not I'm at least running again. The connection string in the web.config is using "Trusted_Connection=True", the appPool is using a domain account with access to both boxes, BUT when I make a change (logged in as me) the name of the service account (appPool identity) is still logged in the audit tables. I also manually granted full permissions to the service account on the webapp folder. What do I need to do in order to log my name, not the service account, in the audit tables? Everything I'm reading says I need to establish a trusted connection between the two servers.

  • Which upgrade path for disk IO bound postgres server?

    - by user41679
    Hi all, We currently have a Sun x4270 with 2xquad core Xeon Nehalmen 2.93ghz cores (16 threads), 72 gig of ram and 16 x 10k SAS disks split between the os raid 1, a partition for the Write Ahead Logs which is raid 10 and a partition for the database tables and indexes which is also raid 10, all xfs. I'm currently evaluating which path to go down in terms of upgrades. We'll be sharding the DB at some point soon, but for now I need to focus on hardware upgrades specifically. The machine is not CPU or memory bound at all at the moment, just IOWait is become an issue. The machine is mostly write access as we have a heavy caching layer. We're seeing about 300 write IOPS average on both the database partitions. We don't have any additional storage infrastructure like a Fiber Channel or ISCSI network. Budget isn't too much of a concern, something inline with the size of this server (i.e no $1m IBM machines) Space is ok on the DB side of things, we're running out obviously but there's also some reduction we can do. Additional space would be good though. My current thoughts are either: * ISCSI SAN, possible with 10Gbit network that has solid state acceleration. * FusionIO card / Sun F20 card (will the FusionIO card work in the Sun box? * DAS shelf (something like this http://www.broadberry.co.uk/das-direct-attached-storage-servers/cyberstore-224s-das) which a combination of 15k sas disks and some Intel X25-E drives for DB indexes etc) what would I need to put in the x4270 to add a DAS shelf? I think it's a SAS HBA card, do I have to use Sun's own card or will any PCI Express card work? Anything else??? what would you guys do from your experience? I appreciate it's a lot of questions, but I haven't expanded a DB machine for a number of years and the landscape has changed dramatically since then! Any advice or feedback would be very much appreciated. Let me know if there's anything else I can clarify. Thanks in advance!

  • Finding underlying cause of Window 7 Account corruption.

    - by Carl Jokl
    I have been having trouble with my Sister's computer which I built. It is running Windows 7 Ultimate x64. The problem is that I have had problems with the accounts becoming corrupted. First problems manifest themselves in the form of Windows saying the profile failed to be loaded properly and a temporary profile. Eventually the account will not allow login at all. An error message along the lines the authentication service failing the login. I have found information about this problem and how to fix it. The problem being that something has corrupted the account profile and backing up and recreating the accounts fixes the problem. I have been able to fix things and get logins working again but over the period of usually about a week it happens again. Bit by bit the accounts corrupt and then it is back to square one. I am frustrated because I don't know what the underlying cause of the problem is i.e. what is causing the accounts to be corrupted in the first place. At the moment I am just treating the symptoms. I was hoping someone who may have more experience with dealing with this problem might be able to help me find the root cause. Some articles suggest that Norton Internet Security is a big culprit of this problem which is installed. I could try uninstalling Norton and see if it helps. The one thing which is different about this computer to any other I have built is that it has a solid state drive. Actually it has both a hard drive and solid state drive. The documents and settings i.e. the Users directory is stored on the hard drive. This was done following an article about moving the user account data onto a separate drive on Windows 7 which I found on the Internet. Moving the User accounts is more of a pain under Windows 7 and this solution involved creating a low level file system link to the folder from the boot drive (Solid State) to the Hard Drive. The idea is that the computer behaves just as if it is accessing the User's folder from the boot drive but actually the data is stored on the hard drive. This may have nothing to do with the cause of the problem but due to the problem being user account corruption it is a possibility I have not been able to rule out. Any help would be appreciated as I would be glad to see the back of this problem.

  • SQL Server Remote Connections

    - by Barry
    Hi, I am at my wits end with trying to access a remote SQL Server 2008 R2 Express instance. Here are the following that I have tried. 1) I enabled remote connections in the instance properties. 2) I enabled sql server and windows authentication mode and created an account to log in using sql server authentication. 3) I started the SQL Server Browser service 4) I forwarded ports 1433 and 1434 on the router to the IP address of the machine hosting SQL Server. 5) I turned off firewalls on both the Machine running the instance and the router. 6) http://www.yougetsignal.com/tools/open-ports/ I used this to check whether or not both ports were open and it says that they are closed. I have the SQL Server Express instance running and the browser running. I have configured it to allow remote connections yet, it tells me they are both closed. I'm pretty confused at this stage. On the client Machine I am trying to connect using the following format machineip\SQLEXPRESS with SQL Server Management Studio Express. Thanks in advance

  • Connect to Apache times out randomly

    - by Amadan
    We are trying to set up an Apache server on a remote machine, but we experience strange behaviour. Checking with telnet remote.machine 80, one of these things happen randomly: Connect and serve content normally (no delay) Connect after a long pause Connect normally, then time out without response Timeout on connect Once connected, the request seems to be processed normally. These things do not occur if I connect from that machine directly to localhost 80. The Apache is dedicated, as is the server it runs on (runs only this one application, no-one else is using it for anything else). I am not an administrator of the remote site, and I do not know the network architecture over there, but apparently it's firewalled: (HTTP port is open, SSH port is IP-restricted, most others are closed). If there was any one pattern, I might have some ideas, but this variety of symptoms baffles me. Any ideas as to what could be causing this? Apache is 2.2; Server version is: Linux version 2.6.9-22.ELsmp ([email protected]) (gcc version 3.4.4 20050721 (Red Hat 3.4.4-2)) #1 SMP Mon Sep 19 18:32:14 EDT 2005

  • Avoid "privacy pitfalls" in Windows and Linux?

    I have a Windows and a Linux machine. In Windows, everytime I visit a site, a lot of cache/history files are created on my machine. I setup my Firefox to don't save anything. ...but Windows saves a lot of "temp" files, some strange files I opened in registry (like video names). Each video I open in VLC is shown in "Last shown videos". In windows, all files opened can be found at "Recent opened files" as well. A lot of these privacy configurations can be tweaked (VLC and "Recent opened files" in Windows) - it's a PITA doing it individually, but it's possible - but there isn't a guide to these "internal" privacy traces that are left on Windows installation. In Linux, I just know there are these problems in app level (like VLC). My question is: is there a complete guide to avoid undesirable traces of what I did/watch/used in my Windows machine? (Delete everytime the PC is restarted, or even avoiding recording these info at all) Is there a website with configuration guides to different types of software? I would like to know about Linux privacy pitfalls as well.

  • centos 6.3 kvm external ip forwarding to guests

    - by user1111702
    I have a centos 6.3 server with kvm installed. The server has 4 external ips and one NIC. 176.9.xxx.xx1 176.9.xxx.xx2 176.9.xxx.xx3 176.9.xxx.xx4 I use the following configuration ifcfg-eth0 as slave to ifcfg-br0 the configuration in ifcfg-eth0 is DEVICE=eth0 ONBOOT=yes BRIDGE=br0 HWADDR=14:da:e9:b3:8b:99 and in the ifcfg-br0 DEVICE=br0 TYPE=Bridge BOOTPROTO=static BROADCAST=176.9.xxx.xxx IPADDR=176.9.xxx.xx1 NETMASK=255.255.255.0 SCOPE="peer 176.9.xxx.xxx" and I have 3 more aliases for br0 , br0:1 to get the trafic from the second external ip DEVICE=br0:1 IPADDR=176.9.xxx.xx2 NETMASK=255.255.255.248 ONBOOT=yes br0:2 to get the trafic from the third external ip DEVICE=br0:1 IPADDR=176.9.xxx.xx3 NETMASK=255.255.255.248 ONBOOT=yes br0:3 to get the trafic from the second external ip DEVICE=br0:1 IPADDR=176.9.xxx.xx4 NETMASK=255.255.255.248 ONBOOT=yes The above settings work fine and I recieve the trafic from all the external ips. My problem is that I want to pass the trafic from external ip to specific virtual guest on my server. ie trafic that comes from 176.9.xxx.xxx2 must pass to virtual machine 1 176.9.xxx.xxx3 must pass to virtual machine 2 176.9.xxx.xxx4 must pass to virtual machine 3 Can you please help me how to achieve this ? What are the settings on the host and what should I do to the guests. Thank you in advance

  • 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.

  • Winamp playing sound but no video

    - by Greg Sansom
    I am having problems playing video in Winamp (the movie I am trying to play is an AVI - not sure if other formats work). I have installed the K-Lite Codec Pack, and the video does work in Winamp Classic. I can also play the video in Winamp on another machine (although I can't remember the exact configuration details of that machine - and I don't think they're relevant). There are a few symptoms: The content of the Video view is either empty, transparent, or displays rendering from other programs. Opening the Visualization view shows the following error: MILKDROP ERROR DirectX initialization failed (GetDeviceCaps). This means that no valid 3D-accelerated display adapter could be found on your computer. If you know this is not the case, it is possible that your graphics subsystem is unstable; please try rebooting your computer and then try to run the plugin again. Otherwise, please install a 3D-accelerated display adapter. Trying to open streams via the SHOUTCast TV plugin shows Error opening video output, and the video does not open. Opening the file with WMC causes the following error (although the movie still plays): Error creating DX9 allocation presenter CreateDevice failed D3DERR_NOTAVAILABLE There are no warnings displayed in Device Manager, although the display adapter is the standard Windows one. Running DxDiag shows no problems (codec for Video listed as XviD 1.1.2 Final). GSpot reports that codecs are installed. System specs: - Windows Server 2008 r2 Standard 64-bit, with latest updates; - .NET 3.5.1 installed; - Winamp v5.6.01 (latest version); - DirectX 11 (Latest version); - K-Lite Codec Pack 7.0.0 (Full); - Machine is HP DC7600 - full specs here. Please comment if there is any more information which will help to diagnose the problem.

  • Preventing DDOS/SYN attacks (as far as possible)

    - by Godius
    Recently my CENTOS machine has been under many attacks. I run MRTG and the TCP connections graph shoots up like crazy when an attack is going on. It results in the machine becoming inaccessible. My MRTG graph: mrtg graph This is my current /etc/sysctl.conf config # Kernel sysctl configuration file for Red Hat Linux # # For binary values, 0 is disabled, 1 is enabled. See sysctl(8) and # sysctl.conf(5) for more details. # Controls IP packet forwarding net.ipv4.ip_forward = 0 # Controls source route verification net.ipv4.conf.default.rp_filter = 1 # Do not accept source routing net.ipv4.conf.default.accept_source_route = 0 # Controls the System Request debugging functionality of the kernel kernel.sysrq = 1 # Controls whether core dumps will append the PID to the core filename # Useful for debugging multi-threaded applications kernel.core_uses_pid = 1 # Controls the use of TCP syncookies net.ipv4.tcp_syncookies = 1 # Controls the maximum size of a message, in bytes kernel.msgmnb = 65536 # Controls the default maxmimum size of a mesage queue kernel.msgmax = 65536 # Controls the maximum shared segment size, in bytes kernel.shmmax = 68719476736 # Controls the maximum number of shared memory segments, in pages kernel.shmall = 4294967296 net.ipv4.conf.all.rp_filter = 1 net.ipv4.tcp_syncookies = 1 net.ipv4.icmp_echo_ignore_broadcasts = 1 net.ipv4.conf.all.accept_redirects = 0 net.ipv6.conf.all.accept_redirects = 0 net.ipv4.conf.all.send_redirects = 0 net.ipv4.conf.all.accept_source_route = 0 net.ipv4.conf.all.rp_filter = 1 net.ipv4.tcp_max_syn_backlog = 1280 Futher more in my Iptables file (/etc/sysconfig/iptables ) I only have this setup # Generated by iptables-save v1.3.5 on Mon Feb 14 07:07:31 2011 *filter :INPUT ACCEPT [1139630:287215872] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [1222418:555508541] Together with the settings above, there are about 800 IP's blocked via the iptables file by lines like: -A INPUT -s 82.77.119.47 -j DROP These have all been added by my hoster, when Ive emailed them in the past about attacks. Im no expert, but im not sure if this is ideal. My question is, what are some good things to add to the iptables file and possibly other files which would make it harder for the attackers to attack my machine without closing out any non-attacking users. Thanks in advance!

  • Any way to know what files were in a broken ZFS pool?

    - by Erik Tjernlund
    I have a large ZFS pool of 4 combined drives. Now, the filesystem can not be mounted: pool: tank state: UNAVAIL status: One or more devices could not be opened. There are insufficient replicas for the pool to continue functioning. action: Attach the missing device and online it using 'zpool online'. see: http://www.sun.com/msg/ZFS-8000-3C scan: none requested config: NAME STATE READ WRITE CKSUM tank UNAVAIL 0 0 0 insufficient replicas c10t0d0 ONLINE 0 0 0 c8t0d0 UNAVAIL 0 0 0 cannot open c8t1d0 ONLINE 0 0 0 c10t1d0 ONLINE 0 0 0 Probably a broken drive (c8t0d0). I'm not overly concerned by the loss of the data, but I'd love to know exactly which files were in that pool. Is there any way to get a listing of what files were there?

  • About to go live: virtual dedicated server or cloud?

    - by morpheous
    I am about to launch my startup company, and we will be going live in a few weeks time. We have really tight budgetary constraints, since we are bootstrapping - and would prefer not to raise external capital. I cant use shared hosting because I need more control of the server machine (for technical reasons - e.g. using proprietary extensions to PHP, Apache and in the database layer as well) - but want to control costs and dont want to go fully private server route, until we have determined the market size etc. So the only real alternatives AFAIK is between virtual server and the cloud. At the moment, cloud services seem a bit "vague" to me. My understanding is that they allow an entity to outsource its IT infrastructure, which in my mind (at least), is indistinguishable from what a hosting provider provides (at least from a functional point of view) - I would like to seek some clarification on exactly what the difference between the two is. Back to my original question, my requirements are: IT infrastructure that can scale with growth Ability to have control of the machine (for e.g. to install our internally developed libraries etc) Backup software that is flexible and comprehensive enough (yet simple to use), that allows a (secured) backup strategy to be implemented. On this issue, I have always wondered where the actual backed up data was stored (since the physical machines are remote, and one cant get access to any actual tapes etc backed onto). I would also like some advice and recommendations in this area. Regarding data size, I am expecting the dataset to be increasing by a few megabytes of data (originally, say 10Mb, in about a years time, possibly 50Mb) every day. As an aside, I have decided to deploy on a Debian server (most of my additional libraries etc were compiled and built on a Debian machine). Mindful of all of the above, I would like some advice (and reason) as to which route to take. I would also like some advice on which backup software to use, from people who have walked a similar path.

  • v2v of RHEL5 box - issues with retaining MAC address

    - by Alex Berry
    For the last week we have been troubleshooting a customer's Red Hat Virtual Machine running on ESXi. We've been using Veeam to try to create a replica off-site and have been having getting it to work on a decent schedule and recently we noticed that there were issues with orphaned snapshots while looking at the datastore. You can see several snapshots in the same folder and it's causing issues with replication and backup, so we decided the cleanest way was to v2v the machine to another datastore so that we had a clean single-vmdk setup to work with, this is where our trouble started. We first started off with a v2v using vmware converter and connecting to the powered on machine as we were having issues doing an offline v2v. This copied fine but when I tried to set a static MAC using this article http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=507 the new VM wouldn't take the address, it simply obtained a new MAC, received a dhcp lease and then would only boot up to a blank red screen, never the login screen. So the next step was to do an offline v2v, once we finally got it working. Same thing, followed the kb to the letter and still it wouldn't take the MAC. I then tried it again and upon completion I compared both old and new VMX file, copying every identifier and variable possible, then unregistered both VMs, uploaded the new VMX file and booted, only to see the same results. Finally I did the same as above but I copied the disk using DD to a second attached vmdk and then attached this to the new VM, and still no luck. After downloading the modified VMX file after the first boot and comparing it to the original I created I found that the bios uuid had changed from the one I typed in manually, so I'm assuming this may be the snagging point, but I have no idea. I've never had this issue before on a P2V and I'm just wondering if someone could shed some light on this, maybe it's to do with RHEL licencing?
