  • Would knowing Python help with creating iPhone applications?

    - by Josh
    Here is what the apple site says: With Snow Leopard, Mac OS X makes it easy to use scripting languages as full application development tools. Snow Leopard ships with support for the RubyCocoa Bridge and the PyObjC bridge. These two bridges give developers access not only to system APIs, but to Cocoa frameworks such as AppKit and Core Data, enabling you to build fully native Mac OS X applications in Ruby or Python. The RubyCocoa and PyObjC bridges allow you to freely mix code written in Objective-C with code written in the scripting language. You can quickly build prototypes and then optimise by implementing performance-critical pieces in Objective-C. How could Python help in this case?

  • ProCurve 1800 switch issue

    - by user98651
    I recently deployed ProCurve 1800-24G switches in place of some older ProCurve 2424M switches in my network. However, I'm having a serious problem with the switch connected to the router. It seems, every night when our Windows 2008 R2 server (off site) runs a backup to a iSCSI target (on site) [facilitated through a PPTP tunnel] the LAN loses connectivity with the router. To clarify, there is only one router which is connected to the switch affected by this problem. The only way to resolve the issue is to either reboot the router or pull the ethernet cable that goes to the router and plug it back in. During the outage, clients cannot receive DHCP requests, DNS requests, ping, or do anything else with the router in this state. Now, neither the switch or router are configured extensively and the issue only seems to have surfaced with the new switch in place. I have tried a number of things including replacing cables, rebooting and checking the switch configuration (it is literally as basic as you can get at this point-- flat LAN, no trunking). Interestingly, the router shows (accessed externally) no changes in configuration or status during this state but similarly cannot ping or access other hosts on the network. This issue occurs in different stages of backup (ie, different amounts transferred). I've also dumped packets from the switch into WireShark but cannot seem to find any anomaly yet (I'm looking at packets around the time the issue appeared and at the time when I reset the NIC). Any suggestions for what to look for? Ideas on what could be causing this? I'm seeing some transmit/receive errors on the NIC from both the router and switch side but nothing serious when compared to the total packet counts. I'm seriously doubting hardware at this point, as I have tried another switch, different cables, and a different NIC on the router.

  • How to break terrain (in blender) into Chunks for a game engine

    - by Red
    I've created an island in blender. 2048x2048 blender units. The engine developer wants me to split the terrain into 128x128 "chunks" so that would be 16x16 "chunks" from a top down view. The engine isn't using height maps, in order to allow caves, 3d overhangs, etc. I'm not in charge of the engine, so suggestions about that aren't needed here :/ I just need a good, seamless way to split a terrain mesh into 16x16 pieces without leaving holes. I'm very new to blender, so baby steps are very much welcomed :) Here's a quick render of what i've got so far. I added a plane to show sea level but i've since removed it. http://i.imgur.com/qTsoC.png

  • Windows - Website unaccessible only on windows pcs in LAN

    - by DorentuZ
    For serveral days now, a website isn't accessible on a single pc in the LAN. On the other pc's, it works just fine. And it's just a single website that's not accessible as far as I know of. The website generates a timeout on every single web browser I've tried (IE8, Firefox and Chrome). However, traceroute, nmap and telnet all work just fine. I've even tried multiple user accounts and safe mode, but that didn't work either. As a side note: using a linux live cd did work and I could access the website without any problems. The hosts file is the windows default, the ip- and dns settings on the network adapter normal as well. No strange processes are running and no viruses found. According to tcpview and netstat there are connections to the domain, but every request in the browser results in a timeout.. Any idea what's happening? Update: All of the computers on the network running Windows (any version) are showing this problem now. The website is still working under linux and mac osx. So, it has to be related to some kind of windows update (although I haven't installed any on one computer in the past week, which I've set to do manual updates only)..

    I am stuck with a very annoying problem which does not allow me to even install Ubuntu on my laptop (Dell Vostro 1510). In a simple walk through of the problematic scenario... I boot the Ubuntu from a boot able CD. I got to a point where it ask for the language options, I select the English as my option using arrows keys and press enter. Then the option come where a.) try from the live cd b.) install ubuntu c.) etc etc Is needed to be selected. For which I press enter. Once I press enter... In any of the next steps of installing Ubuntu, my keypad and touch pad does not work. P.S.: My Batteries are completely dried Up... Can't use batteries.

  • How to bind mouse buttons to keys?

    - by Callum Rogers
    I have a Logitech MX400 Laser Mouse which has 5 buttons + 4 for vertical/horizontal scrolling. I would like it set up so instead of horizontal scrolling pressing right on the scrollwheel will send Ctrl+Tab and left will send Ctrl+Shift+Tab, which will allow me to cycle through tabs in browsers. Also, it would be nice if I could remap the middle button to one of the ones on the side as it is really hard to press down. Another bonus would be if I could write a script that allows me to define what buttons do what dependent on which window is currently active. I have tried using xmodmap but I could only see how to rearrange buttons, not have them send key signals. Thanks in advance. Button Map (using xev): Left 1 Middle 2 Right 3 ScrollUp 4 ScrollDown 5 ScrollLeft 6 ScrollRight 7 Backward 8 Forward 9

  • Rundeck get verbose output of command executing on node

    - by Leon Stafford
    I have Rundeck executing a remote script, which is in python is using print statements to return output normally such as: $ python mytest.py PASS: Condition 1 passed PASS: Condition 2 passed PASS: and so on... When I run this via Rundeck, however, it doesn't show me the same print generated outputs as above. In Rundeck's most detailed Debug output mode, I only receive the following: 06:31:12 Permanently added 'myremotenode.com' (RSA) to the list of known hosts. 06:31:12 SSH_MSG_NEWKEYS sent 06:31:12 SSH_MSG_NEWKEYS received 06:31:12 SSH_MSG_SERVICE_REQUEST sent 06:31:13 SSH_MSG_SERVICE_ACCEPT received 06:31:13 Authentications that can continue: publickey,password,keyboard-interactive 06:31:13 Next authentication method: publickey 06:31:13 Authentication succeeded (publickey). 06:31:13 /cygdrive/c/Program Files (x86)/Mozil... 06:32:06 Adding reference: ant.PropertyHelper 06:32:06 Setting project property: sshexec.output -> /cygdrive/c/Prog... I know that the remote script is actually executing just as usual, as I'm receiving other emails generated by the ~30min long script. Obviously, I don't want to have to wait 30mins to see the result of each print statement within the python script. How can I get the same level of output in Rundeck as I do in the bash shell directly?

  • Postfix Whitelist before recipient restrictions

    - by GruffTech
    Alright. Some background. We have an anti-spam cluster trucking about 2-3 million emails per day, blocking somewhere in the range of 99% of spam email from our end users. The underlying SMTP server is Postfix 2.2.10. The "Frontline defense" before mail gets carted off to SpamAssassin/ClamAV/ ect ect, is attached below. ...basic config.... smtpd_recipient_restrictions = reject_unauth_destination, reject_rbl_client b.barracudacentral.org, reject_rbl_client cbl.abuseat.org, reject_rbl_client bl.mailspike.net, check_policy_service unix:postgrey/socket ...more basic config.... As you can see, standard RBL services from various companies, as well as a Postgrey service. The problem is, I have one client (out of thousands) who is very upset that we blocked an important email of theirs. It was sent through a russian freemailer who was currently blocked in two of our three RBL servers. I explained the situation to them, however they are insisting we do not block any of their emails. So i need a method of whitelisting ANY email that comes to domain.com, however i need it to take place before any of the recipient restrictions, they want no RBL or postgrey blocking at all. I've done a bit of research myself, http://www.howtoforge.com/how-to-whitelist-hosts-ip-addresses-in-postfix seemed to be a good guide at first, almost fixing my problem, But i want it to accept based on TO address, not originating server.

  • .XML Sitemaps and HTML Sitemaps Clarification

    - by MSchumacher
    I've got a website with about 170 pages and I want to create an effective Sitemap for it as it is long due. The website is internally linked very well but I still want to take advantage of creating a sitemap to allow SE's to crawl my site easier and to hopefully increase my websites PR. Though I am slightly confused to what I must do: Is it necessary to create a .xml sitemap AND a HTML Sitemap (both)? ... Because I've never worked with .xml ... where do I put this file once it's created? In the Root folder? So I assume that this sitemap.xml is ONLY to be read by spiders and NOT by website visitors. IE: No visitor on my website is going to visit the page sitemap.xml, am I correct? ... Hence why I should also create an HTML sitemap (sitemap.htm)?

  • What is the minimal steps to setup a client-server network using Windows Server 2008 R2 standard?

    - by Motivated Student
    Background I have One computer server with Win Server 2008 R2 standard installed but it has not been configured. This server has 2 LAN adapters. One adapter is connected to ISP and the other one connected to HUB/Switch. Other computers working as clients are connected to the same HUB/Switch to which the server is connected. IP Printers, IP scanners, IP camera are also connected to the same HUB/Switch. Note: I am a newbie. I only know how to plug RJ-45 sockets and assembly computer peripherals. I have no prior experience in Windows Server at all. Please teach me from the newbie's point of view. Objective I want to establish the following: Each client can access the internet, printers, scanners after it has been successfully authenticated by the server. Unauthenticated clients cannot access the internet, printers, etc. The server hosts a local site. Clients can browse internally using a private domain www.company.com. If the same domain name has been used by other on the internet, my private domain must override the public domain.

  • Issue 15: Oracle Exadata Marketing Campaigns

    - by rituchhibber
         PARTNER FOCUS Oracle ExadataMarketing Campaign Steve McNickleVP Europe, cVidya Steve McNickle is VP Europe for cVidya, an innovative provider of revenue intelligence solutions for telecom, media and entertainment service providers including AT&T, BT, Deutsche Telecom and Vodafone. The company's product portfolio helps operators and service providers maximise margins, improve customer experience and optimise ecosystem relationships through revenue assurance, fraud and security management, sales performance management, pricing analytics, and inter-carrier services. cVidya has partnered with Oracle for more than a decade. RESOURCES -- Oracle PartnerNetwork (OPN) Oracle Exastack Program Oracle Exastack Optimized Oracle Exastack Labs and Enablement Resources Oracle Engineered Systems Oracle Communications cVidya SUBSCRIBE FEEDBACK PREVIOUS ISSUES Are you ready for Oracle OpenWorld this October? -- -- Please could you tell us a little about cVidya's partnering history with Oracle, and expand on your Oracle Exastack accreditations? "cVidya was established just over ten years ago and we've had a strong relationship with Oracle almost since the very beginning. Through our Revenue Intelligence work with some of the world's largest service providers we collect tremendous amounts of information, amounting to billions of records per day. We help our clients to collect, store and analyse that data to ensure that their end customers are getting the best levels of service, are billed correctly, and are happy that they are on the correct price plan. We have been an Oracle Gold level partner for seven years, and crucially just two months ago we were also accredited as Oracle Exastack Optimized for MoneyMap, our core Revenue Assurance solution. Very soon we also expect to be Oracle Exastack Optimized DRMap, our Data Retention solution." What unique capabilities and customer benefits does Oracle Exastack add to your applications? "Oracle Exastack enables us to deliver radical benefits to our customers. A typical mobile operator in the UK might handle between 500 million and two billion call data record details daily. Each transaction needs to be validated, billed correctly and fraud checked. Because of the enormous volumes involved, our clients demand scalable infrastructure that allows them to efficiently acquire, store and process all that data within controlled cost, space and environmental constraints. We have proved that the Oracle Exadata system can process data up to seven times faster and load it as much as 20 times faster than other standard best-of-breed server approaches. With the Oracle Exadata Database Machine they can reduce their datacentre equipment from say, the six or seven cabinets that they needed in the past, down to just one. This dramatic simplification delivers incredible value to the customer by cutting down enormously on all of their significant cost, space, energy, cooling and maintenance overheads." "The Oracle Exastack Program has given our clients the ability to switch their focus from reactive to proactive. Traditionally they may have spent 80 percent of their day processing, and just 20 percent enabling end customers to see advanced analytics, and avoiding issues before they occur. With our solutions and Oracle Exadata they can now switch that balance around entirely, resulting not only in reduced revenue leakage, but a far higher focus on proactive leakage prevention. How has the Oracle Exastack Program transformed your customer business? "We can already see the impact. Oracle solutions allow our delivery teams to achieve successful deployments, happy customers and self-satisfaction, and the power of Oracle's Exa solutions is easy to measure in terms of their transformational ability. We gained our first sale into a major European telco by demonstrating the major performance gains that would transform their business. Clients can measure the ease of organisational change, the early prevention of business issues, the reduction in manpower required to provide protection and coverage across all their products and services, plus of course end customer satisfaction. If customers know that that service is provided accurately and that their bills are calculated correctly, then over time this satisfaction can be attributed to revenue intelligence and the underlying systems which provide it. Combine this with the further integration we have with the other layers of the Oracle stack, including the telecommunications offerings such as NCC, OCDM and BRM, and the result is even greater customer value—not to mention the increased speed to market and the reduced project risk." What does the Oracle Exastack community bring to cVidya, both in terms of general benefits, and also tangible new opportunities and partnerships? "A great deal. We have participated in the Oracle Exastack community heavily over the past year, and have had lots of meetings with Oracle and our peers around the globe. It brings us into contact with like-minded, innovative partners, who like us are not happy to just stand still and want to take fresh technology to their customer base in order to gain enhanced value. We identified three new partnerships in each of two recent meetings, and hope these will open up new opportunities, not only in areas that exactly match where we operate today, but also in some new associative areas that will expand our reach into new business sectors. Notably, thanks to the Exastack community we were invited on stage at last year's Oracle OpenWorld conference. Appearing so publically with Oracle senior VP Judson Althoff elevated awareness and visibility of cVidya and has enabled us to participate in a number of other events with Oracle over the past eight months. We've been involved in speaking opportunities, forums and exhibitions, providing us with invaluable opportunities that we wouldn't otherwise have got close to." How has Exastack differentiated cVidya as an ISV, and helped you to evolve your business to the next level? "When we are selling to our core customer base of Tier 1 telecommunications providers, we know that they want more than just software. They want an enduring partnership that will last many years, they want innovation, and a forward thinking partner who knows how to guide them on where they need to be to meet market demand three, five or seven years down the line. Membership of respected global bodies, such as the Telemanagement Forum enables us to lead standard adherence in our area of business, giving us a lot of credibility, but Oracle is also involved in this forum with its own telecommunications portfolio, strengthening our position still further. When we approach CEOs, CTOs and CIOs at the very largest Tier 1 operators, not only can we easily show them that our technology is fantastic, we can also talk about our strong partnership with Oracle, and our joint embracing of today's standards and tomorrow's innovation." Where would you like cVidya to be in one year's time? "We want to get all of our relevant products Oracle Exastack Optimized. Our MoneyMap Revenue Assurance solution is already Exastack Optimised, our DRMAP Data Retention Solution should be Exastack Optimised within the next month, and our FraudView Fraud Management solution within the next two to three months. We'd then like to extend our Oracle accreditation out to include other members of the Oracle Engineered Systems family. We are moving into the 'Big Data' space, and so we're obviously very keen to work closely with Oracle to conduct pilots, map new technologies onto Oracle Big Data platforms, and embrace and measure the benefits of other Oracle systems, namely Oracle Exalogic Elastic Cloud, the Oracle Exalytics In-Memory Machine and the Oracle SPARC SuperCluster. We would also like to examine how the Oracle Database Appliance might benefit our Tier 2 service provider customers. Finally, we'd also like to continue working with the Oracle Communications Global Business Unit (CGBU), furthering our integration with Oracle billing products so that we are able to quickly deploy fraud solutions into Oracle's Engineered System stack, give operational benefits to our clients that are pre-integrated, more cost-effective, and can be rapidly deployed rapidly and producing benefits in three months, not nine months." Chris Baker ,Senior Vice President, Oracle Worldwide ISV-OEM-Java Sales Chris Baker is the Global Head of ISV/OEM Sales responsible for working with ISV/OEM partners to maximise Oracle's business through those partners, whilst maximising those partners' business to their end users. Chris works with partners, customers, innovators, investors and employees to develop innovative business solutions using Oracle products, services and skills. Firstly, could you please explain Oracle's current strategy for ISV partners, globally and in EMEA? "Oracle customers use independent software vendor (ISV) applications to run their businesses. They use them to generate revenue and to fulfil obligations to their own customers. Our strategy is very straight-forward. We want all of our ISV partners and OEMs to concentrate on the things that they do the best – building applications to meet the unique industry and functional requirements of their customer. We want to ensure that we deliver a best in class application platform so the ISV is free to concentrate their effort on their application functionality and user experience We invest over four billion dollars in research and development every year, and we want our ISVs to benefit from all of that investment in operating systems, virtualisation, databases, middleware, engineered systems, and other hardware. By doing this, we help them to reduce their costs, gain more consistency and agility for quicker implementations, and also rapidly differentiate themselves from other application vendors. It's all about simplification because we believe that around 25 to 30 percent of the development costs incurred by many ISVs are caused by customising infrastructure and have nothing to do with their applications. Our strategy is to enable our ISV partners to standardise their application platform using engineered architecture, so they can write once to the Oracle stack and deploy seamlessly in the cloud, on-premise, or in hybrid deployments. It's really important that architecture is the same in order to keep cost and time overheads at a minimum, so we provide standardisation and an environment that enables our ISVs to concentrate on the core business that makes them the most money and brings them success." How do you believe this strategy is helping the ISVs to work hand-in-hand with Oracle to ensure that end customers get the industry-leading solutions that they need? "We work with our ISVs not just to help them be successful, but also to help them market themselves. We have something called the 'Oracle Exastack Ready Program', which enables ISVs to publicise themselves as 'Ready' to run the core software platforms that run on Oracle's engineered systems including Exadata and Exalogic. So, for example, they can become 'Database Ready' which means that they use the latest version of Oracle Database and therefore can run their application without modification on Exadata or the Oracle Database Appliance. Alternatively, they can become WebLogic Ready, Oracle Linux Ready and Oracle Solaris Ready which means they run on the latest release and therefore can run their application, with no new porting work, on Oracle Exalogic. Those 'Ready' logos are important in helping ISVs advertise to their customers that they are using the latest technologies which have been fully tested. We now also have Exadata Ready and Exalogic Ready programmes which allow ISVs to promote the certification of their applications on these platforms. This highlights these partners to Oracle customers as having solutions that run fluently on the Oracle Exadata Database Machine, the Oracle Exalogic Elastic Cloud or one of our other engineered systems. This makes it easy for customers to identify solutions and provides ISVs with an avenue to connect with Oracle customers who are rapidly adopting engineered systems. We have also taken this programme to the next level in the shape of 'Oracle Exastack Optimized' for partners whose applications run best on the Oracle stack and have invested the time to fully optimise application performance. We ensure that Exastack Optimized partner status is promoted and supported by press releases, and we help our ISVs go to market and differentiate themselves through the use our technology and the standardisation it delivers. To date we have had several hundred organisations successfully work through our Exastack Optimized programme." How does Oracle's strategy of offering pre-integrated open platform software and hardware allow ISVs to bring their products to market more quickly? "One of the problems for many ISVs is that they have to think very carefully about the technology on which their solutions will be deployed, particularly in the cloud or hosted environments. They have to think hard about how they secure these environments, whether the concern is, for example, middleware, identity management, or securing personal data. If they don't use the technology that we build-in to our products to help them to fulfil these roles, they then have to build it themselves. This takes time, requires testing, and must be maintained. By taking advantage of our technology, partners will now know that they have a standard platform. They will know that they can confidently talk about implementation being the same every time they do it. Very large ISV applications could once take a year or two to be implemented at an on-premise environment. But it wasn't just the configuration of the application that took the time, it was actually the infrastructure - the different hardware configurations, operating systems and configurations of databases and middleware. Now we strongly believe that it's all about standardisation and repeatability. It's about making sure that our partners can do it once and are then able to roll it out many different times using standard componentry." What actions would you recommend for existing ISV partners that are looking to do more business with Oracle and its customer base, not only to maximise benefits, but also to maximise partner relationships? "My team, around the world and in the EMEA region, is available and ready to talk to any of our ISVs and to explore the possibilities together. We run programmes like 'Excite' and 'Insight' to help us to understand how we can help ISVs with architecture and widen their environments. But we also want to work with, and look at, new opportunities - for example, the Machine-to-Machine (M2M) market or 'The Internet of Things'. Over the next few years, many millions, indeed billions of devices will be collecting massive amounts of data and communicating it back to the central systems where ISVs will be running their applications. The only way that our partners will be able to provide a single vendor 'end-to-end' solution is to use Oracle integrated systems at the back end and Java on the 'smart' devices collecting the data – a complete solution from device to data centre. So there are huge opportunities to work closely with our ISVs, using Oracle's complete M2M platform, to provide the infrastructure that enables them to extract maximum value from the data collected. If any partners don't know where to start or who to contact, then they can contact me directly at [email protected] or indeed any of our teams across the EMEA region. We want to work with ISVs to help them to be as successful as they possibly can through simplification and speed to market, and we also want all of the top ISVs in the world based on Oracle." What opportunities are immediately opened to new ISV partners joining the OPN? "As you know OPN is very, very important. New members will discover a huge amount of content that instantly becomes accessible to them. They can access a wealth of no-cost training and enablement materials to build their expertise in Oracle technology. They can download Oracle software and use it for development projects. They can help themselves become more competent by becoming part of a true community and uncovering new opportunities by working with Oracle and their peers in the Oracle Partner Network. As well as publishing massive amounts of information on OPN, we also hold our global Oracle OpenWorld event, at which partners play a huge role. This takes place at the end of September and the beginning of October in San Francisco. Attending ISV partners have an unrivalled opportunity to contribute to elements such as the OpenWorld / OPN Exchange, at which they can talk to other partners and really begin thinking about how they can move their businesses on and play key roles in a very large ecosystem which revolves around technology and standardisation." Finally, are there any other messages that you would like to share with the Oracle ISV community? "The crucial message that I always like to reinforce is architecture, architecture and architecture! The key opportunities that ISVs have today revolve around standardising their architectures so that they can confidently think: “I will I be able to do exactly the same thing whenever a customer is looking to deploy on-premise, hosted or in the cloud”. The right architecture is critical to being competitive and to really start changing the game. We want to help our ISV partners to do just that; to establish standard architecture and to seize the opportunities it opens up for them. New market opportunities like M2M are enormous - just look at how many devices are all around you right now. We can help our partners to interface with these devices more effectively while thinking about their entire ecosystem, rather than just the piece that they have traditionally focused upon. With standardised architecture, we can help people dramatically improve their speed, reach, agility and delivery of enhanced customer satisfaction and value all the way from the Java side to their centralised systems. All Oracle ISV partners must take advantage of these opportunities, which is why Oracle will continue to invest in and support them." -- Gergely Strbik is Oracle Hardware and Software Product Manager for Avnet in Hungary. Avnet Technology Solutions is an OracleValue Added Distributor focused on the development of the existing Oracle channel. This includes the recruitment and enablement of Oracle partners as well as driving deeper adoption of Oracle's technology and application products within the IT channel. "The main business benefits of ODA for our customers and partners are scalability, flexibility, a great price point for the high performance delivered, and the easily configurable embedded Linux operating system. People welcome a lower point of entry and the ability to grow capacity on demand as their business expands." "Marketing and selling the ODA requires another way of thinking because it is an appliance. We have to transform the ways in which our partners and customers think from buying hardware and software independently to buying complete solutions. Successful early adopters and satisfied customer reactions will certainly help us to sell the ODA. We will have more experience with the product after the first deliveries and installations—end users need to see the power and benefits for themselves." "Our typical ODA customers will be those looking for complete solutions from a single reseller partner who is also able to manage the appliance. They will have enjoyed using Oracle Database but now want a new product that is able to unlock new levels of performance. A higher proportion of potential customers will come from our existing Oracle base, with around 30% from new business, but we intend to evangelise the ODA on the market to see how we can change this balance as all our customers adjust to the concept of 'Hardware and Software, Engineered to Work Together'. -- Back to the welcome page

  • Python or C server hosting for indie development

    - by Richard Fabian
    I've written a lot of the game, but it's singleplayer. Now we want to join up and play together. I want to host it like an MMO, but haven't got any personal ability to host (no static IPs or direct access to a reasonable router that will allow me to port forward) so I wondered if there were any free / very cheap hosting solutions for people developing games that need to develop their MMO side. In my case it's a world server for a 2D game where the world map can be changed by the players. So, GAE sounds expensive, as there would be quite a few updates per second (I heard they bill for data updates but not for download, but can't find refernce to billing anywhere on the FAQs) I'd prefer to be able to write the server in python as that's what the game is written in (with pygame), but C is fine, and maybe even better as it might prompt me to write some more performant world generator code ;)

  • How to configure VirtualBox server for performance at home

    - by BluJai
    I currently have two physical Ubuntu Server 10.10 servers at home: one serves as our firewall/router/DHCP/VPN server and the other performs double-duty as a file server and a VirtualBox host for an Ubuntu Desktop 10.10 machine which I use from remote connections (via NoMachine) for many thin-client purposes which are irrelevant to my question. What I'd like to accomplish is to consolidate the two physical machines into one which is a dedicated VirtualBox host (most likely running Ubuntu Server 10.10). Note that I'd like to stick with VirtualBox (if possible) because I'm most comfortable with it and use it on a daily basis at both home and work. Specifically, I plan to have one VM set up as file server, another as the firewall/router/DHCP/VPN (or possibly split those a bit) and a third, which is the only current VM (already VirtualBox), which is the thin-client host. My question comes down to performance and/or recommendations about the file server VM. The file server hosts about 6 terabytes of data across 4 drives. What I'd like to do is use raw disk access from the VM directly to the existing disks. However, I'm curious what performance advantage/disadvantage that would have as compared to using shared folders from the VM host and basically just have the whole drive served as a shared folder to the VM which would then serve it to the other machines on the network. I don't know if virtual disks would even work in this scenario and I certainly wouldn't want a drive to be filled with just a single file which is 1.5 TB (disk image). To add understanding of context, but not to get additional advice, I want to virtualize these machines because I intend to regularly use the snapshot capabilities of VirtualBox for the system disks (which will be virtual drives) of the VMs and I have some physical space/power needs to address (as I mentioned, this is at home).

  • XAML2CPP 1.0.1.0

    - by Valter Minute
    I upgraded XAML2CPP to fix some bugs and support some new features that will be used in my next tutorial step (that I hope to publish very soon!). Bug fixed: the listbox selection changed event was generated with an incorrect prototype events generated by the XAML tree root element (UserControl) were not handled. New features: XAML2CPP generates panels (dynamically generated XAML subtrees that may be added to a page) and user controls (those will be the object of my next post, stay tuned!). XAML2CPPXRValue class has been added to XAML2CPPbase.h. This class will allow single-line declaration of XRValue objects (I’m lazy!) and destroys automatically objects and string XRValues when the object itself is destroyed. You can download the latest XAML2CPP release here: http://cid-9b7b0aefe3514dc5.skydrive.live.com/self.aspx/.Public/XAML2CPP.zip

  • Name resolution not working with ipv6 on centos

    - by jolivier
    I just installed CentOs 6.3 on a server to be installed in a data center, but cannot get name resolution / curl to work. I know this is because of it trying to use ipv6, since ping google.com works, curl -4 google.com works, but not curl google.com. I removed the ipv6 adress from the interface and it does not change anything. This is very problematic since most system tools like yum fail at name resolution currently. Browsers like Firefox work because they might be using another tool for name resolution than the one use by curl. I managed to fix this on workstations by completely disabling ipv6 following tutorials like this one / hardcoding name resolution in /etc/hosts. But since I am here configuring a server which will be later installed in a remote data center, I would like not to mess up, understand what is going on and fix it properly. Besides, I will face the same issue with more servers to come so I would really appreciate your help in understanding this problem and how to solve it. I would be happy to provide more information if needed to help understand what is going on. The current network configuration is a small enterprise network, with a DNS server (let's call it A) configured once a long time ago. dig google.com and dig -4 google.com are both refused by the A DNS. But this is also true for my workstation on which curl is working (and yes they both use the same A DNS server). Indeed this faulty server and my workstation have multiple nameservers in /etc/resolv.conf, and the second one is working fine for both of them, so if I remove A from my resolv.conf everything works fine!

  • iPad Jailbreak &ndash; On The Lam In A Single Day

    - by David Totzke
    Exploits to jailbreak the iPhone are well known.  The iPad runs on the iPhone 3.2 firmware.  What this means is that the iPad was shipped with known security vulnerabilities that would allow someone to gain root access to the device. Nice. It’s not like these are security vulnerabilities that are known but have no exploits.  The exploits are numerous and freely available. Of course, if you fit the demographic, you probably have nothing to worry about. Magical and Revolutionary?  Hardly. Dave Just because I can…

  • Adjust resolution in xfce4 virtualbox guest guest

    - by David
    I have Virtualbox 4.1.2_ubuntur3859 installed on an Ubuntu 11.10 host, running a guest ubuntu server 10.04 with xfce4 and xorg installed with no-install-recommends. I have installed guest additions, but the maximum resolution in the display settings is 800x600. I have read related questions: How to change resolution of the VirtualBox (Ubuntu guest and host)? Higher screen resolution in VirtualBox? upgrading VirtualBox 3.2.10 breaks my guest Ubuntu screen resolution Ubuntu as guest OS (with Vista host) stuck at 800x600 resolution but none contain the solution to my issue. Am I missing any particular packages that would allow me to change resolution? I would like to keep the machine as small as possible.

  • How can I manage AWS VPC ssh access accounts and keys across multiple instances?

    - by deitch
    I am setting up a standard AWS VPC structure: a public subnet some private subnets, hosts on each, ELB, etc. Operational network access will be via either an ssh bastion host or an openvpn instance. Once on the network (bastion or openvpn), admins use ssh to access the individual instances. From what I can tell all of the docs seem to depend on a single user with sudo rights and a single public ssh key. But is that really best practice? Isn't it much better to have each user access each host under their own name? So I can deploy accounts and ssh public keys to each server, but that rapidly gets unmanageable. How do people recommend managing user accounts? I've looked at: IAM: It doesn't like like IAM has a method for automatically distributing accounts and ssh keys to VPC instances. IAM via LDAP: IAM doesn't have an LDAP API LDAP: set up my own LDAP servers (redundant, of course). Bit of a pain to manage, still better than managing on every host, especially as we grow. Shared ssh key: rely on the VPN/bastion to track user activities. I don't love it, but... What do people recommend? NOTE: I moved this over from accidentally posting in StackOverflow.

  • Varnish configuration, NamevirtualHosts, and IP Forwarding

    - by Brent
    I currently have a bunch of NameVirtualHost based websites, load balanced between 3 apache2 servers using ldirectord. I would like to insert varnish as a reverse-web-proxy between ldirectord and apache in the following way: a request comes in to ldirectord it is then load balanced between the 3 apache2 servers and varnish, with a weight of 1 for the webservers, and 99 for varnish (so if varnish is rebooted, the webservers will take over seamlessly) varnish will then load balance its requests between my apache2 servers. However, the varnish part is not working. I wonder whether this has to do with the fact that my apache servers use x.x.x.x:80 for their NameVirtualHosts, instead of *:80? (they have to do this, since each server hosts multiple IP addresses) Or perhaps it has to do with the need for IP Forwarding to be set up on the varnish server? (I did echo 1 /proc/sys/net/ipv4/ip_forward on this server, is that sufficient?) How can I debug this problem? ldirectord doesn't produce logs of what it does with each request (and if it did, I would be overwhelmed with information since I'm serving hundreds of requests per second) varnish log shows the ldirectord server connecting to it every 5 seconds, but nothing else. I have set up a test site using this configuration, but it fails - no apache access logs, no applicable varnish logs.
