  • Windows Home 7 and virtualization

    - by progtick
    so apparently, you can't use VirtualBox etc with Windows Home 7. because you would be using two licenses instead of one. So other users that tried virtualization with Windows Home Premium 7, did you just end up using another OS like Ubuntu etc? Did you find a workaround for using Windows? When I say virtualization, I mean virtual machine of sort - where dangerous websites can be visited, nasty applications can be tried etc.

  • Wireless Bridging between BTVoyager 2500V-8C and Belkin G+ Mimo Or D-link DSL-G604T

    - by Morgeh
    Anyone got any ideas how to set up a wireless network bridge between the routers mentioned above? I have a router connected to the internet in one part of the house (BTVoyager) but the wireless range doesnt reach to the other end of the house :-( I also have two spare wireless routers(Belkin G+ Mimo and D-Link DSL-G604T) but as far as I can tell neither of them support wireless bridging.

  • Why ethernet calbes must be ended with specific arrangement

    - by adopilot
    I just accepted that ethernet cables CAT 5 and more must be ended with specific arrangement. I learned when I ending my cables to take attention that either end must be in same arrangement(568A or 568B ). Sometime I get stacked with my fellow servant that they claim that Cable should work if just arrangement at both side are same even if it is not in 568A or 568B layouts. My experience said that it is not true, but I am now looking for some technical argument to prove that.

  • Pass a Delphi class to a C++ function/method that expects a class with __thiscall methods.

    - by Alan G.
    I have some MSVC++ compiled DLL's for which I have created COM-like (lite) interfaces (abstract Delphi classes). Some of those classes have methods that need pointers to objects. These C++ methods are declared with the __thiscall calling convention (which I cannot change), which is just like __stdcall, except a this pointer is passed on the ECX register. I create the class instance in Delphi, then pass it on to the C++ method. I can set breakpoints in Delphi and see it hitting the exposed __stdcall methods in my Delphi class, but soon I get a STATUS_STACK_BUFFER_OVERRUN and the app has to exit. Is it possible to emulate/deal with __thiscall on the Delphi side of things? If I pass an object instantiated by the C++ system then all is good, and that object's methods are called (as would be expected), but this is useless - I need to pass Delphi objects. Edit 2010-04-19 18:12 This is what happens in more detail: The first method called (setLabel) exits with no error (though its a stub method). The second method called (init), enters then dies when it attempts to read the vol parameter. C++ Side #define SHAPES_EXPORT __declspec(dllexport) // just to show the value class SHAPES_EXPORT CBox { public: virtual ~CBox() {} virtual void init(double volume) = 0; virtual void grow(double amount) = 0; virtual void shrink(double amount) = 0; virtual void setID(int ID = 0) = 0; virtual void setLabel(const char* text) = 0; }; Delphi Side IBox = class public procedure destroyBox; virtual; stdcall; abstract; procedure init(vol: Double); virtual; stdcall; abstract; procedure grow(amount: Double); virtual; stdcall; abstract; procedure shrink(amount: Double); virtual; stdcall; abstract; procedure setID(val: Integer); virtual; stdcall; abstract; procedure setLabel(text: PChar); virtual; stdcall; abstract; end; TMyBox = class(IBox) protected FVolume: Double; FID: Integer; FLabel: String; // public constructor Create; destructor Destroy; override; // BEGIN Virtual Method implementation procedure destroyBox; override; stdcall; // empty - Dont need/want C++ to manage my Delphi objects, just call their methods procedure init(vol: Double); override; stdcall; // FVolume := vol; procedure grow(amount: Double); override; stdcall; // Inc(FVolume, amount); procedure shrink(amount: Double); override; stdcall; // Dec(FVolume, amount); procedure setID(val: Integer); override; stdcall; // FID := val; procedure setLabel(text: PChar); override; stdcall; // Stub method; empty. // END Virtual Method implementation property Volume: Double read FVolume; property ID: Integer read FID; property Label: String read FLabel; end; I would have half expected using stdcall alone to work, but something is messing up, not sure what, perhaps something to do with the ECX register being used? Help would be greatly appreciated. Edit 2010-04-19 17:42 Could it be that the ECX register needs to be preserved on entry and restored once the function exits? Is the this pointer required by C++? I'm probably just reaching at the moment based on some intense Google searches. I found something related, but it seems to be dealing with the reverse of this issue.

  • nginx + Jetty - thousands of connections stuck in LAST_ACK

    - by virulence
    I have a FreeBSD machine with jails -- two in particular, one that runs nginx and another that runs a Java program that accepts requests via Jetty (embedded mode) Jetty receives upwards of 500 requests/sec constantly and there has been an issue lately where I will constantly have over 60,000 connections in the LAST_ACK state between nginx and jetty. Distribution of all connections (includes some other services, particularly php-fpm) root@host:/root # netstat -an > conns.txt root@host:/root # cat conns.txt | awk '{print $6}' | sort | uniq -c | sort -n 18 LISTEN 112 CLOSING 485 ESTABLISHED 650 FIN_WAIT_2 1425 FIN_WAIT_1 3301 TIME_WAIT 64215 LAST_ACK Distribution of nginx - jetty connections root@host:/root # cat conns.txt | grep '10.10.1.57' | awk '{print $6}' | sort | uniq -c | sort -n 1 3 CLOSE_WAIT 3 LISTEN 18 FIN_WAIT_2 125 ESTABLISHED 64193 LAST_ACK I'd prefer every request to fully close the connection. Clients requests are about 10 minutes apart from each other so connections must be closed. Some of the connections, tcp4 0 0 10.10.1.50.46809 10.10.1.57.9050 LAST_ACK tcp4 0 0 10.10.1.50.46805 10.10.1.57.9050 LAST_ACK tcp4 0 0 10.10.1.50.46797 10.10.1.57.9050 LAST_ACK tcp4 0 0 10.10.1.50.46794 10.10.1.57.9050 LAST_ACK tcp4 0 0 10.10.1.50.46790 10.10.1.57.9050 LAST_ACK tcp4 0 0 10.10.1.50.46789 10.10.1.57.9050 LAST_ACK tcp4 0 0 10.10.1.50.46771 10.10.1.57.9050 LAST_ACK etc.. On Jetty's end I've set maxIdleTime to 2000 -- before this all connections were in ESTABLISHED but they are now LAST_ACK On Jetty's end I've set Connection: close (i.e response.setHeader(HttpHeaders.CONNECTION, HttpHeaderValues.CLOSE);) Jetty never reports a lot of open connections -- always very few. PF/IPFW is not currently being used nginx - reset_timedout_connection is on I cannot figure out how to get nginx or jetty to forcibly close the connection, is this simply something that needs to be fixed in Jetty so that it fully closes the socket after the request finishes? Thanks a lot in advance EDIT: forgot my nginx config for the proxy setup- proxy_pass http://10.10.1.57:9050; proxy_set_header HTTP_X_GEOIP $http_x_geoip; proxy_set_header GEOIP_COUNTRY_CODE $geoip_country_code; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_set_header Connection ""; proxy_http_version 1.1; EDIT2: Forcing Jetty to close the connection via request.getConnection().getEndPoint().close() does nothing -- it's obvious the connection IS being closed (as it's in LAST_ACK) but why isn't it getting past this? Is Nginx keeping the connection open to the backend for some reason?

  • Laserjet Experts: How many power cycles per month?

    - by marienbad
    I recently got a nice Laserjet 8100DN for my house. I will probably never print more than 1% of its rated monthly duty cycle. But it runs some fairly noisy fans 24/7 if it's left on, so I am in the habit of turning the machine off as soon as I'm done with it. So, for all you who have a lot of experiencing administrating workgroup LaserJets, do you think I'll end up killing it from too many on-off cycles?

  • Nested form problem in Rails : NoMethodError in Show

    - by brianheys
    I'm trying to build a simple product backlog application to teach myself Rails. For each product, there can be multiple product backlog entries, so I want to create a product view that shows the product information, all the backlog entries for the product, and includes a nested form for adding more backlog entries. Everything works until I try to add the form to the view, which then results in the following error: NoMethodError in Products#show Showing app/views/products/show.html.erb where line #29 raised: undefined method `pblog_ref' for #<Product:0x10423ba68> Extracted source (around line #29): 26: <%= f.error_messages %> 27: <p> 28: <%= f.label :pblog_ref %><br /> 29: <%= f.text_field :pblog_ref %> 30: </p> 31: <p> 32: <%= f.label :product %><br /> The product view where the problem is reported is as follows (the partial works fine, so I won't include that code): <h1>Showing product</h1> <p> <b>Product ref:</b> <%=h @product.product_ref %> </p> <p> <b>Description:</b> <%=h @product.description %> </p> <p> <b>Owner:</b> <%=h @product.owner %> </p> <p> <b>Status:</b> <%=h @product.status %> </p> <h2>Product backlog</h2> <div id="product-backlog"> <%= render :partial => @product.product_backlogs %> </div> <% form_for(@product, ProductBacklog.new) do |f| %> <%= f.error_messages %> <p> <%= f.label :pblog_ref %><br /> <%= f.text_field :pblog_ref %> </p> <p> <%= f.label :product %><br /> <%= f.text_field :product %> </p> <p> <%= f.label :description %><br /> <%= f.text_field :description %> </p> <p> <%= f.label :owner %><br /> <%= f.text_field :owner %> </p> <p> <%= f.label :status %><br /> <%= f.text_field :status %> </p> <p> <%= f.submit 'Create' %> </p> <% end %> <%= link_to 'Edit', edit_product_path(@product) %> | <%= link_to 'Back', products_path %> This is the Product model: class Product < ActiveRecord::Base validates_presence_of :product_ref, :description, :owner has_many :product_backlogs end This is the ProductBacklog model: class ProductBacklog < ActiveRecord::Base belongs_to :product end These are the routes: map.resources :product_backlogs map.resources :products, :has_many => :product_backlogs I've checked what I'm doing against the Creating a weblog in 15 minutes with Rails 2 screencast, and in principle I seem to be doing the same thing as him - only his nested comments form works, and mine doesn't! I hope someone can help with this, before I turn mad! I'm sure it's something trivial.

  • Should we increase local port range limit on busy memcached servers

    - by Majid Azimi
    nixcraft has a tutorial on configuring memcached server(link) at the end says: For busy memcached server you need to increase system file descriptor and IP port limits here is the code to do so: # Increase system IP port limits net.ipv4.ip_local_port_range = 2000 65000 why should we do this? memcached is a server and it will respond to clients with its listening port which is 11211 by default. So we shouldn't be limited by local port range.(net.ipv4.ip_local_port_range) The only limit is file descriptors. local port range should be a limit for servers like squid which generate local traffic

  • Building Debian package - pre-installation check

    - by debianuser
    I am building a custom Debian package and during the installation, I would like the package to check for available diskspace and only proceed if there is enough space. I would like this to happen during re-install as well. I tried adding bash code to do the check in preinst and prerm file(for re-installations) with exit 1 if the check fails, but the installer went ahead and copied files and I end up with a broke installation. What am I doing wrong?

  • Websites on Ubuntu 8.04 LTS with Plesk are infected with viruses

    - by Paddington
    I am running Plesk 9.5 on Ubuntu 8.04 LTS and have about 15 websites infected with some malicious code appended to the end of java files. I have installed Clamav and it has managed to pickup the infected files which have a pattern of starting with either /*km0ae9gr6m*/ or /*gootkitstart*/ and ending with /*qhk6sa6g1c*/ or /*gootkitend*/ My Plesk panel is up to date and security patches were installed. How can I isolate the security vulnerability on the server?

  • Script to check a shared Exchange calendar and then email detail

    - by SJN
    We're running Server and Exchange 2003 here. There's a shared calendar which HR keep up-to-date detailing staff who are on leave. I'm looking for a VB Script (or alternate) which will extract the "appointment" titles of each item for the current day and then email the detail to a mail group, in doing so notifying the group with regard to which staff are on leave for the day.

  • how to close open ftp connections?

    - by KnockKnockWhosThere
    I use FileZilla, and I thought when a session ended, it automatically closed the ftp connection, but that doesn't appear to have happened because now I'm getting a "530 Sorry, the maximum number of connections (10) for your host are already connected." error. Is there a way to find any open ftp connections and close them from my end? Or, do I have to contact the host?

  • How to setup GIT repo on server with need for working dir (non- bare)

    - by OrangeTux
    I want to have configurate a GIT repo for a website. Multiple users will have a clone of the repo on their local machine and on the end of each day they push their work to the server. I can setup a bare repo, but I want a working dir/non-bare repository. The idea is that the working dir of the repository will the root folder for the website. At the end of each day all changes will be visible directly. But I can't find a way to do this. Initializing the server repo with git init gives the following error when a client is trying to push some files: git push origin master [email protected]'s password: Counting objects: 3, done. Writing objects: 100% (3/3), 227 bytes, done. Total 3 (delta 0), reused 0 (delta 0) remote: error: refusing to update checked out branch: refs/heads/master remote: error: By default, updating the current branch in a non-bare repository remote: error: is denied, because it will make the index and work tree inconsistent remote: error: with what you pushed, and will require 'git reset --hard' to match remote: error: the work tree to HEAD. remote: error: remote: error: You can set 'receive.denyCurrentBranch' configuration variable to remote: error: 'ignore' or 'warn' in the remote repository to allow pushing into remote: error: its current branch; however, this is not recommended unless you remote: error: arranged to update its work tree to match what you pushed in some remote: error: other way. remote: error: remote: error: To squelch this message and still keep the default behaviour, set remote: error: 'receive.denyCurrentBranch' configuration variable to 'refuse'. To ssh://[email protected]/home/orangetux/www/ ! [remote rejected] master -> master (branch is currently checked out) error: failed to push some refs to 'ssh://[email protected]/home/orangetux/www/' So I'm wondering if this the right way to setup a GIT repo for a website? If so, how do I have to do this? If not, what is a better way to setup a GIT repo for the development of a website? EDIT you can't push to a non-bare repository Oke, clear. But whats the way to solve my problem? Create a bare repository on the server and have a clone of this repo on the same server in the htdocs folder? This looks a bit clumsy to me. To see the result of a commit I've to clone the repository each time.

They used to run and end without abending, but now they open and stay open and I have to setup the task to quit them by force before their next scheduled run. I've thought about installing CURL or WGET, but is there a way to do this with R2 without going to that step? Regards.
