  • Performance difference between MacBook Pro (2.8 GHz) vs Air (1.7 GHz)?

    - by jonathanconway
    I'm comparing these two Apple laptops: MacBook Pro (13", 2011 model): 2.8GHz dual-core Intel Core i7 processor with 4MB shared L3 cache 4GB (two 2GB SO-DIMMs) of 1333MHz DDR3 SDRAM AMD Radeon HD 6770M graphics processor with 1GB of GDDR5 memory on 2.4GHz configuration MacBook Air (13", 2011 model): 1.7GHz dual-core Intel Core i5 with 3MB shared L3 cache 4GB of 1333MHz DDR3 onboard memory Intel HD Graphics 3000 processor with 384MB of DDR3 SDRAM shared with main memory There's definitely a gap between them in terms of CPU speed and graphics, but what practical difference would this make on a day-to-day basis? On the one hand, I love the sleek, thin appearance of the Air. On the other hand, I don't want a machine that's going to be dog-slow when doing tasks such as running Virtual Machines, dual-booting to Windows and running multiple instances of Visual Studio, and maybe some light gaming. Is there going to be a major difference that makes the MacBook Pro a more attractive purchase?

  • cassandra node discovery

    - by eQuiNoX__
    I just set up a 3 node system with ip addresses "192.168.0.101", "192.168.0.102", "192.168.0.103". I have set the seeds value on the configuration of all three machines as seeds: "192.168.0.101,192.168.0.102,192.168.0.103" However, on running nodetool on any of them, only the 103 machine gets discovered. node101:/opt/cassandra/apache-cassandra-0.8.5/bin# ./nodetool ring -h 192.168.0.101 Address DC Rack Status State Load Owns Token 192.168.0.103 datacenter1 rack1 Up Normal 151.96 KB 100.00% 38174485210079977599903748344879358256 Could someone tell me where the problem lies?

  • Are SANs unreliable?

    - by chaos
    So at the place where I wear one of my various hats, this one representing a development rather than admin role, there's been an initiative to move to SANs. So far, I have been spectacularly unimpressed. First it was this behavior where, when MySQL databases are on the SAN, the first few tables that anything tries to hit after the system boots come up as nonexistent and MySQL has to be restarted before it realizes they're actually there. Then today, on multiple systems (including the primary SVN repository, ever-so-wonderfully) we get SAN mounts spewing IO errors and the filesystems going into read-only, which is the kind of behavior I expect from directly mounted naked disks, not fault-tolerant managed storage. Right now, I'm at the point where if I were putting together a project and somebody said "hey we should use SANs", my response would be "GTFO". So basically I want to know whether my experience is typical or even common, or whether I'm having some kind of freakishly bad luck with SANs. The systems these SANs are attached to are all CentOS machines, if that's relevant.

  • Configure VPN to access remote LAN network on Windows7

    - by PiotrK
    Situation: I have two Windows7 machines (PC and laptop). I've set PC as VPN server and laptop as VPN client using default built-in W7 network tools. I've disabled use default gateway in remote network on client machine, so client don't try to route all communication through VPN. I've routed port 1723 (TCP/UDP) on NAT to my server and enabled IPSec/PPTP/L2TP passthrough I've put my laptop in indepedent network (basically I've connected it via 3G network), connected to VPN server and checked ipconfig /all I've get: IP Address: 192.168.1.101 Mask: 255.255.255.255 Gateway: (none) LAN mask in server LAN network is 255.255.255.0 - I am surely missing something obvious, but Google doesn't give me any good advices; How can I access local LAN network from remote VPN client? How can I access local shared documents?

  • On a router, how do I block wan access for a particular machine without blocking its access to the local network?

    - by HappyEngineer
    On my tp-link TL-WR1043ND router I want to prevent a particular machine from having access to the WAN while still allowing that machine to access other machines on the LAN. My assumption is that I need to do something in the "Access Control" section, however the problem is that it wants an ip range or domain name for the target of the rule. The router uses DHCP to get an address from the WAN, so I don't have any guarantee what the ip address of the wan will be. If the answer is that it's not possible with this router, could someone describe how to do it using OpenWRT instead?

  • On setting up Apache and IIS to share the same IP

    - by miCRoSCoPiCeaRthLinG
    Hello, There are two different web-apps running on two (physically) different servers on our network... one of IIS and another one on Apache - both on port 80 since two machines are accessible by different IPs on our internal network. Now I want to expose both these services to the world. My idea is to somehow make the incoming connection redirect to the appropriate server based on user's choice of subdomain. Example xxx.domain.com maps to the IIS (Internal IP: 1.2.3.4) yyy.domain.com maps to Apache (Internal IP: 5.6.7.8) To the world, both these servers will share the same public IP. What kind of a configuration am I looking at and how do I go about trapping the subdomain requests and redirecting to the appropriate server? Thanks, m^e

  • What's the simplest configuration of SVN on a Windows Server to avoid plain text password storage?

    - by detly
    I have an SVN 1.6 server running on a Windows Server 2003 machine, served via CollabNet's svnserve running as a service (using the svn protocol). I would like to avoid storing passwords in plain text on the server. Unfortunately, the default configuration and SASL with DIGEST-MD5 both require plain text password storage. What is the simplest possible way to avoid storing passwords in plain text? My constraints are: Path-based access control to the SVN repository needs to be possible (currently I can use an authz file). As far as I know, this is more-or-less independent of the authentication method. Active directory is available, but it's not just domain-connected windows machines that need to authenticate: workgroup PCs, Linux PCs and software that uses PySVN to perform SVN operations all need to be able to access the repositories. Upgrading the SVN server is feasible, as is installing additional software.

  • Centos iptables blocks after reboot

    - by bilal
    I have a Centos5 installation with kvm on my server. I am using nat portforwarding to ssh my virtual machines. I have several iptables rules and saved then in /etc/sysconfig/iptables. After reboot, I see all these rules when I type service iptables status but I am getting a connection refused error. After typing service iptables restart everything works. I don't understand, why do I need to restart iptables again? Doesn't it restart on reboot?

  • pxelinux hanging when booting client machine

    - by Blasphemophagher
    I'm kind of new to all of this, so please forgive any vagueness/misunderstandings on my part. I'm using pxelinux and VMs to create CentOS 6.0 machines that have the same install every time. I have a new VM set to boot from network, but in the process of booting up it gets stuck at "Loading 10.1.1.20:/pxelinux.0" (10.1.1.20 is the address of the server it's getting info from). pxelinux conf: http://pastebin.com/4XfZZPY1 I'm pretty sure all my config files are correct, could it be VirtualBox related? I have both the building server and the new client set to Host-only adapter and PCNET-FAST.

  • Nearest PC equivalent to Mac Target Disk Mode?

    - by username
    Mac firmware has a special boot mode that allows you to offer its internal hdd to another computer as an external disk (you just connect the two machines via an IEEE 1394 cable). Only the second machine needs a functioning OS installed. Any good suggestions for something similar on the PC side of things? Block level access isn't important to me, I'd just like to be able to copy files off it. It doesn't matter to me if it uses Ethernet, IEEE 1394, or wifi - I just like having a quick way to access files on a client PC. Is there any single-purpose Linux distro specially designed to do this? It'd be nice to have something super simple, quickbooting, and small that I could install on a USB drive. I used to use Knoppix, but it's overkill as a Target Mode replacement.

  • Linksys WRT54Gx as Repeater Bridge

    - by Robert Koritnik
    I have a Linksys WRT54Gx router with DD-WRT software working fine. But. Is it possible to use it as a Repeater Bridge when the host router isn't configured to be in the default 192.168.1.1 subnet? I've set everything from these instructions. I've also tried setting repeater router's IP address to be inside host's subnet, setting Gateway + DNS IP addresses... But It still didn't work. Client machines connecting to second router (my Linksys) were configured to use DHCP and also static IPs within host's subnet. Nothing worked. Can anyone tell me how to configure it to make it work?

  • Ultra Low Latency Linux Distribution or Kernel

    - by Zanlor
    I'd like to know if there are any linux distributions that are focused on low latency networking. The area I'm working in is algorithmic trading, and extremely low latency comms between machines is a must. The current h/w we're using is 10g ethernet, we're looking into things like infiniband RDMA and Voltaire VMA I've googled around, and have only been able to find tidbtits of kernel patches, command line options and hardware suggestions. I'm looking for a complete solution, specially built kernel, kernel bypass features, essentially all the goodies rolled up into one package - does such a thing even exist? I ask as a lot of this stuff seems to be a black art, people keep secret what they know works etc.

  • How to set the hostname according to the DNS name on Ubuntu 9.10?

    - by tangens
    Motivation I have to manage a lot of virtual machines that I create by copying a template (VmWare image). Problem Now I have the problem that in the template the file /etc/hostname contains a given name that I want to change for each copy of the template. Facts The network interface is configured by DHCP. DNS entries exist. The system is a Ubuntu 9.10 server. Question I wonder if I can configure the template so that on startup it sets its hostname according to its DNS name. I could create an init script that parses the IP address, makes a DNS lookup and sets the hostname accordingly. But is there an easier way?

  • Run application or script on Windows RDC connection

    - by NickLarsen
    I checked this thread, but it did not solve my exact problem. I need to run a script on when a connection is made across my network using windows remote desktop connection. The thread listed above works for the initial login, however, if I don't log out (which is necessary for some processes running on my network), then it wont run the script again the next time someone connects to the system using remote desktop connection. Previously we were using pcAnywhere to achieve this, however after running into some graphical issues with pcAnywhere, we have decided to move away from it to RDC. For a little more information, we need to have an email sent out anytime a connection is made to particular machines. The login name will always be the same for those systems and we do not log off when closing the connection.

  • Windows 2008R2 two node failover cluster creation fails

    - by Francois Wolmarans
    We have just installed two Windows 2008R2 Enterprise machines with identical hardware. When running the cluster validation everything is ok. When creating the cluster it fails with the following error: An error occurred while creating the cluster. An error occurred creating cluster 'CLUSTER04'. The parameter is incorrect The logfile on the first node where we are running our config from, does not show any errors. On the second node we get: The Cluster service is shutting down because quorum was lost. This could be due to the loss of network connectivity between some or all nodes in the cluster, or a failover of the witness disk. I've double checked and all communication between the servers are fine. Even when creating a one node cluster it gives the error. There are other failover clusters we have setup without any issues.

  • One bigger Virtual Machine in Cloud

    - by flyer
    I just setup virtual machines on one hardware with Vagrant (this is just a test environment, not production!). I want to use a Puppet to configure them and next try to setup OpenStack. I am not sure If I am understanding how this should look at the end. Is it possible to have below architecture with OpenStack after all where I will run one Virtual Machine with e.g. 12 cores? ------------------------------- | VM (12c) | ------------------------------- | NOVA | NOVA | NOVA | ------------------------------- | OpenStack | ------------------------------- | VM (4c) | VM (4c) | VM (4c) | ------------------------------- | Bare Metal (8c) | ------------------------------- I need this information to have a bigger picture to continue.

  • SharePoint 2010 not seeing Active Directory users

    - by user117927
    I'm pretty new to Active Directory and SharePoint but I was given to understand they are supposed to play well together. Now I have successfully set up AD with multiple user accounts that work on any member computer. I have also successfully installed SharePoint 2010 Server on an AD machine. Both the AD server and SharePoint servers are on separate machines (VMs running on ESXi to be precise). I can only log on with user accounts I create on the local server. Furthermore the user browser thing for adding users will only see local users. I've followed the advice here http://technet.microsoft.com/en-us/library/cc262350.aspx#section2 for Classic authentication and also NTLM claims based authentication but to no avail. Is there something fundamental I am getting wrong here? I'd be really thankful for any help you can lend me; I've been googling and scratching my head for a couple of days now. P

  • Does using a single cable to connect two switches create a bottleneck?

    - by Nick
    I realise this may be a stupid question for some, but it's something I've always wondered about. Let's say we have two gigabit switches and all of the devices on the network are also gigabit. If 10 computers connected to switch A need to transfer large amounts of data to a server on Switch B (at the same time), is the maximum transfer speed of each connection limited by the bandwidth of the connection between the two switches? In other words, would each computer only be able to transfer at a speed of one gigabit divided by the 10 machines trying to use the "bridge" between switches? If so, are there any workarounds so that every device can use it's maximum speed from point to point?

  • Client/server application RPC connection gets disconnected very frequently

    - by Chris Thompson
    I have a client/server application that uses RPC for the client to communicate with the server. Fairly regularly, I get an event in the Application log that the RPC connection was disconnected: Client callback failed ((0x80010108) ) I have the Windows Firewall disabled on both machines. I've even run the client on a second computer with a clean Windows XP install without any group policies. This has been going on for a long time and no one has been able to figure out why it's happening. The same client/server app works fine at other client locations. Any thoughts?

  • Changing memory allocator to Jemalloc Centos 6

    - by Brian Lovett
    After reading this blog post about the impact of memory allocators like jemalloc on highly threaded applications, I wanted to test things on a larger scale on some of our cluster of servers. We run sphinx, and apache using threads, and on 24 core machines. Installing jemalloc was simple enough. We are running Centos 6, so yum install jemalloc jemalloc-devel did the trick. My question is, how do we change everything on the system over to using jemalloc instead of the default malloc built into Centos. Research pointed me at this as a potential option: LD_PRELOAD=$LD_PRELOAD:/usr/lib64/libjemalloc.so.1 Would this be sufficient to get everything using jemalloc?

  • Fedora Installation with software repository in DVD does not work

    - by Raks
    I bought a new assembled PC with processor as Core-i3(2120) and Intel H61 motherboard and was trying to install Fedora 16 from a DVD. This DVD contains all the packages so that installation does not require to download packages from internet. I have used this DVD to install Fedora 16 offline many a times though in machines with different hardware configuration. But in this new machine when the installation reaches the stage wherein it asks for Software repository selection I select CD/DVD but the system fails to read the media and throws up an error that it cannot detect the media. THe LED in the DVD writer also indicate that the DVD is not being read. Now there is neither a problem with the DVD or the DVD drive because the installation started from the DVD itself. So what could the problem be, anything in the BIOS that is causing the problem, Is there any way I could utilize the packages already existing in the CD so that I save downloading the packages from DVD

  • How is my ISP DNS hijacking AFTER all these precautions?

    - by user973917
    In IE9 when I search for anything my ISP hijacks google search and I get this result. To add complication to this I've already changed the default DNS servers (OpenDNS) months ago. This only happens in IE9; even after machine reboots and cache flushing. I even have my router (dd-wrt) intercepting all requests for DNS and I am still getting this result. I have all extensions disabled and there are no toolbars. This is IE9 from M$. This is not malware; it happens all machines with IE installed (even IE7/8).

  • hosting environment for delivering FLVs

    - by Gotys
    What would be the ideal hardware setup for pushing lots of bandwith on a tube site? We have ever-expanding cloud storage where users upload the movies, then we have these web-delivery machines which cache the FLV files on its local harddrives and deliver them to users. Each cache machine can deliver 1200 mbits/s , if it has SAS 8 harddrives. Such a cache machine costs us $550/month for 8x160gb -- so each machine can cache only 160GB at any given time. If we want to cache more then 160gb , we need to add another machine..another $550/month..etc. This is very un-economical so I am wondering if we have any experts here who can figure out a better setup. I've been looking into "gluster FS", but I am not sure if this thing can push a lot of bandwith. Any ideas highly appreciated. Thank you!

  • Can a virtual mikrotik box bridge a hyper-v internal network with a hyper-v external network?

    - by mcfrosty
    I am trying to set up a Mikrotik router as a transparent firewall on my network. I got the machine working on a hardware MT box, but my boss wants the MT virtualized. I have been trying the set up where my virtual windows box talks to the Mikrotik via private or internal network on the Hyper-V host. I can get the two machines to talk, but as soon as I set up a bridge on the MT, all traffic ceases between the two. Is it possible to create a bridge for this purpose (having the MT silently in front of my firewalled server)? I could really use some help.
