• Q8300 Core-2 Quad vs X3360 Xeon

  - by alchemical

  I'm looking at this ABMX server, and trying to decide on the CPU. I'm purchasing 2 servers, to be used as dedicated web and DB servers for a web site that has low traffic now but could ramp up quickly. Just trying to decide if it is worth about $200 more (per server) for the Xeon vs the core-2. Passmark rates them at 3567 and 4153, which didn't seem that different. I'm not planning at this point to need virtualization. I did hear rumors that Xeon stands up better in a 24/7 server environment, but heard others say there wasn't that much difference. Planning to run Windows Server 2008, likely the R2 release, with 8GB RAM.

• Returning "200 OK" in Apache on HTTP OPTIONS requests

  - by i.

  I'm attempting to implement cross-domain HTTP access control without touching any code. I've got my Apache(2) server returning the correct Access Control headers with this block: Header set Access-Control-Allow-Origin "*" Header set Access-Control-Allow-Methods "POST, GET, OPTIONS" I now need to prevent Apache from executing my code when the browser sends a HTTP OPTIONS request (it's stored in the REQUEST_METHOD environment variable), returning 200 OK. How can I configure Apache to respond "200 OK" when the request method is OPTIONS? I've tried this mod_rewrite block, but the Access Control headers are lost. RewriteEngine On RewriteCond %{REQUEST_METHOD} OPTIONS RewriteRule ^(.*)$ $1 [R=200,L]

• Migration with SysPrep, ImageX and

  - by Jack Smith

  I know that you can use SysPrep and ImageX to create a prepared image that can be used on several systems but the question is. How well does it work in a corporate environment of moving machines from old hardware off to new harddrives and new hardware? EDIT: The system runs accounting software and databases. So would SysPrep remove all License keys and other information which means would cause problems right? Would something else be a better option even though there are heavy costs involved? Currently, when I clone/copy the drive, Windows will black screen on me. So I need something with differential hardware support?

• Migrating to OSGi?

  - by Paul McKenzie

  We're currently running server-side java apps on windows using JavaServiceWrapper and this has been a good solution for us. We have a small number of Spring-based lightweight applications. But now we need to look at introducing some modularity into our services. To that end I have been thinking about OSGi. I need to know which OSGi containers are ready for prime-time production use in a medium-ish load environment? Eclipse Equinox 3.5.xKnopflerfish 3.xApache Felix 2.xAnything else?

  - by yashbinani

  I have developed a web application which will be deployed in a LAN environemnt. Clients will be Computers/Android Tablets/IPAD In order for communication between client and local server 1) need to assign a static IP to local server. 2) need a domian name mapping for that IP address in Local environment. 3) router should assign the same static IP if it gets restarted etc. I am using a windows XP machine as Local server OS. Do i need to take care of router configurations before buying one, or all routers will have same capability to perform this task. I am not a network specialist, so Sorry if this question sounds stupid. Thanks

• Unable to terminate extra EC2 instances

  - by Deborah Cole

  I'm just setting up my AWS server & I'm trying to use the EC2 Console to terminate some extra instances that I generated via the AWS for Eclipse toolkit's New Project AWS Java Web Project utility. Unfortunately, every time I stop, then terminate such an instance via the EC2 Console, it automatically recreates & reactivates itself! I really don't want to be paying for 4 dev systems when I only need 1, so can somebody please clue me in? Please explain gently... I'm new to this environment.

• VirtualBox Mac - Is it possible re-map a key for a VM

  - by Erin Drummond

  I am running Windows inside VirtualBox on Mac OSX. However, I am frequently copying and pasting/undoing etc using keyboard shortcuts. Because Mac is dumb and tries to be different, common shortcuts such as ctrl+c and ctrl+v are cmd+c and cmd+v on Mac. This creates a problem because I keep trying to use mac-style shortcuts in the VM, or windows-style shortcuts on the Mac (my workflow is, do ASP.NET dev in the VM, but use the Mac hosts browser). What I would like to be able to do is make VirtualBox send "Command" key presses as "Ctrl" to the VM, so that I dont have to keep remembering which environment I am in and thinking about which key combination I need to use. Is this possible?

• Always a path to the internet even in Windows SBS is off

  - by Mark

  Hello all, is it possible to have a configuration in a Windows 2003 SBS environment where in the event that the SBS box crashed/turned off/ or is being worked on that there can still exist a path to the internet for domain users and visitors to still use? I would like to have the standalone router issue DHCP IPs. The primary DNS would point to the SBS, the secondary wouuld point to the ISP DNS Server. My theory was that if someone was using the internet and the SBS box went down they wouldn't be able to access the network shares but still be able to use the internet. (We are moving everything into the clouds with Google Apps Non-Profit) Does this seem like a reasonable configuration? Or are they're pitfalls that I will fall into? Thanks Mark

• Linux file association

  - by Mgccl

  With a desktop environment, there are file associations that goes with it. I'm a minimalistic user, who doesn't use any of such, but still want some kind of file associations to ease my burden. So I'm searching for a program that does something like the following. open file.pdf this will look at the extension, and translate to okular file.pdf. Of course one can always write a bash script to do this. I wonder if there is something existing, so I don't reinvent the wheel.

• Using terminal vs KDE in linux?

  - by Ke

  Hi Im used to using nautilus within centos but have recently just got a VPS and quickly realising that using a KDE is unacceptable in this environment. Although I do find it so much quicker doing things like folder permissions in KDE rather than typing it all out in the terminal? Everyone I speak to says, use the terminal and I should learn this way as opposed to using the KDE, but theres certain things I just dont get How is it possible to make quick changes to scripts and viewing them in a browser etc , without a mouse or using KDE? and only using a terminal?? I am wondering how to develop websites just using the terminal??? How can it be quicker to type out/view permissions etc in the terminal when its instant and just a few clicks in the KDE? Any thoughts are much appreciated. I would love to understand the benefits but just cant seem to see them right now. Cheers Ke.

• OVF Tools error

  - by ToreTrygg

  Hello all, I am trying to use OVF tools 1.0 to create an .ovf appliance split to 4gbs. When I run the following command: ovftool --chunkSize=4gb vi://:@/?ds= e:\test\test.ovf everything starts off fine. It will got for about 15-16% then I get this message: "Error: unable to get NFC ticket for target disk". I have looked online, but cannot find anything that matches this problem. I am using Windows 2k3 as the ovf creation server, and I'm in a ESX 3.5 environment. The ovf must be split into 4gb chunks (or less) so they can be put onto DVDs. Also, when it is done it deletes the files it started to create. Any help would be greatly appreciated.

• What is the best/easiest way to use scripts to analyze network traffic?

  - by yungin

  I'm looking to analyze packets via scripts. I'd like to use something high level. I'm in a mac/linux environment. I'm currently looking at different python+libpcap libraries. Perhaps lua+wireshark too. Maybe tcpdump+bash (but not sure that has a lot of info i can use). I also heard good things about scapy. Not sure. I'm wondering if you have any recommendations? There's quite a few of them out there. What have you found that works best? I'd definitely want something scriptable not something that I need to compile (like c/c++, etc)

• hosting people asking for my account username and password to enable curl and socket function only for me

  - by Jayapal Chandran

  I have hosted my site in a shared environment. My hosting people disabled socket function all together. and they said that we can enable only for you if i given a written statement. I did but they asked for my control panel login details so they will run some kind of script to enable it. Is it right for the hosting company to ask for credentials. They have the total control so why cant they do it? Edit: Before six months many websites in their server got hacked. So they think it would be because of socket functions and had disabled it. They say they can enable it for specific users who do programming using that and that is by email request.

• Distributing Files using a Group Policy on Windows Server 2003

  - by tonedeath

  A piece of software that we use at our office has recently moved to a new licensing system. This means that from now on a new set of license key files will need to be distributed to each of our 25 client installations every year. All of the clients run XP and are part of an AD domain controlled by a Windows 2003 DC. I'm already using group policies to deploy software updates. I gather that this is possible with Group Policy Preferences in Server 2008. I'm just looking for a good method using Server 2003. The same set of files need copying to each client. I also have them hosted on a network share accessible by each client. I'm more of a *nix person, so I'm not particularly up on scripting in a Windows environment.

• Bridging VirtualBox over OpenVPN TAP adapter on Windows

  - by Sean Edwards

  I'm trying to configure a virtual machine (VirtualBox guest running Backtrack 4) with a bridged adapter over a VPN connection. The VPN is is hosted by the cybersecurity club at my university, and connects to a sandboxed LAN designed for penetration testing against various servers that the club has built. My host (Windows 7 Ultimate) connects to the VPN fine and is assigned an IP through DHCP, but for some reason the VM can't do the same thing, and I'm not sure why. It's like OpenVPN is filtering out packets from the MAC address it doesn't recognize. I want the virtual machine to bridge over the VPN connection, because our IT office has very strict policies about what you can and can't do on the network. I want to be able to run active attacks (ARP spoofing, nmap, Nessus scans) in the sandbox environment without risking the traffic accidentally going over the university network and getting my internet access revoked. Bridging over the VPN connection and running all attacks from inside the VM would solve that problem. Any idea why the host can use this interface, but the VM can't?

• Exchange 2010 - No Push notification when when deleting emails from Outlook

  - by ThinkTank

  Hi I'm setting up a Exchange 2010 server for our test environment. I'm running Windows 2008R2 enterprise on this machine. Iv'e also installed all updates available for windows and exchange 2010 including rollup 1 and 2 for exchange that include bugfixes regarding push notifications. My problem is when deleting mail or marking mail as read don't trigger a push notification. The happens when I use webgui, mobile phone and Outlook 2007. When deleting a email in Outlook 2007 the changes get sent to the server since the changes are visible in webgui but not on mobile phone. I get push notifications when I get new emails since new emails appear instantly on the mobile phone. Is this normal behaviour on Exchange 2010? For me it seems a bit funny. If i force sync on mobile phone the changes appear. Iv'e tested this on both iphone and HTC HD2(Running Windows Mobile 6.5) with same results.

• MySQL 5.5 on Windows server is horribly slow

  - by Brad

  I have had no luck getting MySQL 5.5 to be as fast as 5.1 or MariaDB on the exact same hardware/database/environment under Windows server 2003R2 or 2008R2. My benchmarks from our application: MySQL 5.5 + CentOS 5.2 (XenServer Virtual) = 28 seconds (box is "busy" not buried) MariaDB (5.1) + Windows 2003 (Physical box) = 130 seconds (box is 2% busy) MySQL 5.1 + Windows 2003 (Physical box) = 170 seconds (box is 2% busy) MySQL 5.5 + Windows 2003 (Physical box) = 305 seconds (As high as 600 seconds...) (box is 2% busy) The only difference between these runs is the removal of skip-locking and the running of mysql_upgrade.exe to update some tables for stored procs on 5.5. Yes, I know it's a release candidate, I'm feeding that back to MySQL as well. No slow queries are logged, it doesn't think it's being slow, it just is. I'm going to start tearing into the queries themselves to see if the INSERT/SELECT plans have gone buggo on 5.5. Any help would be appreciated! Thanks

• (svh+ssh) getting bash to load my PATH over SSH

  - by Eli Bendersky

  This problem comes up with me trying to make svnserve (Subversion server) available on a server through SSH. I compiled SVN and installed it in $HOME/bin. Local access to it (not through SSH) works fine. Connections to svn+ssh fail due to: bash: svnserve: command not found Debugging this, I've found that: ssh user@server "which svnserve" says: which: no svnserve in (/usr/bin:/bin) This is strange, because I've updated the path to $HOME/bin in my .bashrc, and also added it in ~/.ssh/environment. However, it seems like the SSH doesn't read it. Although when I run: ssh user@server "echo $PATH" It does print my updated path! What's going on here? How can I make SSH find my svnserve? Thanks in advance

• Using LDAP to store customer data

  - by mechcow

  We wish to store some data in 389 Directory Server LDAP that doesn't fit that well into the standard set of schema's that come with the product. Nothing too amazing, things like: when the customer joined are they currently active customer certificate[1] which environment they are using My question is this: should we register with OID and start writing up our own custom schema OR is there a standard schema definition not provided by Directory Server that we can download and use that would fit our needs? Should we munge/hack existing attributes and store the data among there (I'm strongly opposed to this, but would be interested in arguments about why its better than extending)? [1] I know there is a field for this userCertificate but we don't want to use it to authenticate the user for the purposes of binding Using CentOS 5.5 with 389 Directory Server 8.1

• Setting up a Windows Server 2008 R2 DC + Fileserver : native or virtual?

  - by user126890

  I want to deploy a new DC + Fileserver using Windows Server 2008 R2 SP1 Standard Edition on a Dell PowerEdge R410 and iSCSI storage for a small business (~30 people). Should I install the system native on the server or use a virt layer? I don't have a budget for virtualization so i gotta go with something free... What's a better working routine, taking snapshots of vm's or taking backups (Acronis/CloneZilla) of systems? If I use a virt system, I need a GUI for some people in the business to reset the system to a earlier state in emergency situations. I wanted to install phpVirtualBox once but never finished, is it suitable in a productive environment? server specs: Intel Xeon E5620 CPU (2,40GHz, 4C, 12MB Cache) 8GB RAM Dual Rank LV RDIMMs 1333MHz 2x 1TB SATA 7,2K 3,5, RAID1

• Redmine on Redhat/CentOS 5 Without using virtual hosts

  - by flyclassic

  I've have followed all the steps to install Redmine on CentOS 5, except for the Apache part: http://www.redmine.org/projects/redmine/wiki/HowTo_install_Redmine_on_CentOS_5 I do not want to configure a virtualhost as we are not using virtual hosts. Can I configure Redmine to run with http://hostname/redmine? Apparently it doesn't work for my case. Redmine was extracted in to the webserver document root /var/www/html/ called /var/www/html/redmine What I did was added a redmine.conf to /etc/httpd/conf.d/ with the following configuration and restarted the server: <Location "/redmine"> Options Indexes ExecCGI FollowSymLinks -MultiViews Order allow,deny Allow from all AllowOverride all PassengerEnabled On RailsBaseURI /var/www/html/redmine RailsEnv production </Location> now i got this error Further information about the error may have been written to the application's log file. Please check it in order to analyse the problem.

• How to download source, modify source, recompile and build .deb package?

• Glassfish with Webservices on non default port

  - by Rick

  I have a simple web service that I created that deploys perfectly on a default Glassfish V2.1 install on both a windows and a linux system. HOWEVER, In the production environment, Glassfish has the default port for the domain changed from port 8080 to port 80. Now when I try to deploy the web service it will not deploy to the server. The production server is brand new and only was a few webpages on it. Other than the port everything else seems to be the same. I cannot change the port on the production server. In fact I tried to change the port on the linux test server tfrom 8080 to port 80 and I get the same result as the production server. Any ideas - other than don't use glassfish? :)
