• CentOS 6.3 Virtual under OpenVZ cannot ping, host lookups, outbound connections while postfix running

  - by Paul Cravey

  My best theory is that some kernel limit is being hit preventing outbound connections. We have tried basically everything from tcpdumps to provisioning an entirely new virtual server (we do not have this problem on any other virtuals), however the problem somehow carried over, even with new postfix build (working). Emails work, and outbound connections work, so long as postfix does not have too much going on. /proc/user_beancounters shows no limits being hit (show below). Nevertheless, pings fail even to IP addresses. TCP stack appears healthy. Load is low. No iowait. Flushed iptables already. Has anyone experienced anything like this? uid resource held maxheld barrier limit failcnt 3: kmemsize 166216365 170262528 9223372036854775807 9223372036854775807 0 lockedpages 0 0 9223372036854775807 9223372036854775807 0 privvmpages 285727 351885 9223372036854775807 9223372036854775807 0 shmpages 16933 17605 9223372036854775807 9223372036854775807 0 dummy 0 0 0 0 0 numproc 150 303 9223372036854775807 9223372036854775807 0 physpages 314156 326191 0 1280000 0 vmguarpages 0 0 9223372036854775807 9223372036854775807 0 oomguarpages 165355 165355 9223372036854775807 9223372036854775807 0 numtcpsock 89 172 9223372036854775807 9223372036854775807 0 numflock 22 76 9223372036854775807 9223372036854775807 0 numpty 1 2 9223372036854775807 9223372036854775807 0 numsiginfo 0 75 9223372036854775807 9223372036854775807 0 tcpsndbuf 2733472 4371752 9223372036854775807 9223372036854775807 0 tcprcvbuf 1798336 5427296 9223372036854775807 9223372036854775807 0 othersockbuf 491120 1000760 9223372036854775807 9223372036854775807 0 dgramrcvbuf 0 238728 9223372036854775807 9223372036854775807 0 numothersock 361 505 9223372036854775807 9223372036854775807 0 dcachesize 135941831 136114679 9223372036854775807 9223372036854775807 0 numfile 2905 4990 9223372036854775807 9223372036854775807 0 dummy 0 0 0 0 0 dummy 0 0 0 0 0 dummy 0 0 0 0 0 numiptent 8 9 9223372036854775807 9223372036854775807 0 [root@bni /]# ping 4.2.2.1 PING 4.2.2.1 (4.2.2.1) 56(84) bytes of data. --- 4.2.2.1 ping statistics --- 9 packets transmitted, 0 received, 100% packet loss, time 8493ms [root@bni /]# service postfix stop [root@bni /]# ping 4.2.2.1 PING 4.2.2.1 (4.2.2.1) 56(84) bytes of data. 64 bytes from 4.2.2.1: icmp_seq=1 ttl=53 time=8.63 ms 64 bytes from 4.2.2.1: icmp_seq=2 ttl=53 time=8.62 ms 64 bytes from 4.2.2.1: icmp_seq=3 ttl=53 time=8.63 ms 64 bytes from 4.2.2.1: icmp_seq=4 ttl=53 time=8.66 ms Outbound connections of all sorts fail when postfix is running.

• How to setup a virtual machine in Ubuntu desktop to run Debian Server

  - by stickman

  I want to run a virtual machine in my Ubuntu desktop that runs a Debian server. The purpose of this is to generate Debian packages. I have some C++ applications that were originally developed on my Ubuntu machine, and I need to (re)compile them on a Debian server in order to: build Deb packages for deployment on a Debian server make sure that the applications will definitely work on a debian server The idea is so that I can do 90% of my development on Ubuntu (where I am more comfortable), and deploy a binary package that definitely works on Debian. BTW, I am developing on Karmic Kola (Ubuntu 9.10). [Edit] Following the advice I got so far, I have installed debootstrap and Debian 'Lenny' on /srv/chroot/debian_lenny on my machine. I am not sure this is the server version, but in any case I dont think that matters for my purposes (though it would be useful to know how to specifically install the server version). At the moment though, I am like a fish out of water, since there is no GUI, and it is only a console that I have in the chroot jail. I had a look in the home folder (I cheated, by using the KNavigator in Ubuntu), and there are no folders there - which presumably mean that no users have been set up as yet in the Debian "system". I would like to know how to do the following: Download and install the dev tools needed for (re)compiling my C++ apps Copy my projects from the Ubuntu "system" to the Debian "system" After building the binaries, I would like to create a debian binary package containing all of my binaries, so that I can install the package on a Debian server (my remote server)

• Process PHP files from a network share in a vmware virtual machine

  - by nhinkle

  As a testing environment, I have set up a vmware virtual machine running Windows Server 2008 R2. I have Apache and PHP installed (as part of the xampp package). I am doing the development outside of the VM, and so want Apache to serve PHP files from a VM shared folder (which appears as a network share in the VM). I have done this by creating an NTFS symbolic link in Apache's htdocs directory. I can access this directory from the browser, and plain-text files are readable. However, PHP fails to process files, instead returning the following error: Warning: Unknown: failed to open stream: No such file or directory in Unknown on line 0 Fatal error: Unknown: Failed opening required 'C:/xampplite/htdocs/path/to/file.php' (include_path='.;C:\xampplite\php\PEAR') in Unknown on line 0 It appears to be a permissions issue — PHP doesn't seem to be allowed to read the file to process it. However, Apache has no problem opening files in the directory. I cannot figure out how to give PHP the necessary permissions to process the file. Does anybody know of a way to make this work, or else another solution for getting the files into the VM automatically while I develop on the host machine?

• HTTP cache for my virtual machines

  - by MathematicalOrchid

  I have several Linux virtual machines running on my home PC. One of the quirks of Linux is that every time you run a package manager, it wants to "refresh" the configured software repositories - which basically means it wants to download a file from the Internet. If I revert to an earlier snapshot of the VM, then next time I run the package manager it will re-download the exact same data again [since it no longer exists in the VM]. It seems a shame to waste bandwidth endlessly downloading the same data over and over again, so I was wondering if there's some way I can set up some kind of HTTP proxy server that caches downloaded files. I have no idea how you would do such a thing though. In particular, it needs to be set up so that the VMs don't need to "know" that the cache is there; it needs to be transparent. But I don't know how to do that. Any suggestions on what software I'd need to use? It would be nice if I could run it under the Windows host OS, but running a small VM with a Linux guest is also possible...

• Can I boot up a virtual machine natively?

  - by Anshul

  My question is: Is is possible to run a virtual machine natively on your hardware if you have installed the proper drivers etc? In other words, can I use a VHD as a regular hard drive to boot from? The reason I want to do this is that I do both graphics-intensive and audio-intensive work, but my computer is not powerful enough to handle both at the same time and many times I install a bunch of audio programs that I don't want affecting the stability of my graphics programs. Basically I wanted to have sandboxing between the two sets of applications. So I tried running the graphics-intensive programs in a VirtualBox VM and the audio-intensive work natively (simply because it's a pain to route ASIO audio devices in/out of VirtualBox). This kind-of works - the graphics-intensive stuff is tolerable, but still relatively slow, because it's running inside a VM. So my next idea was to just dual-boot and install the graphics and audio programs in separate partitions but I frequently use them in tandem, so it wouldn't be practical to reboot my machine every time I need to use the other set of programs. But I could live with this scenario: If I need to do more audio-intensive stuff, I'll just boot up to the audio partition and run the graphics programs in a VM, and then when I'm working heavily on the graphics part, I'll just boot the graphics partition as a regular OS directly on the hardware. Is this possible? For example by booting up a VHD as a regular hard drive? Or by setting up dual-boot, and every time the audio partition is shut down, synchronize the graphics VM VHD with the native graphics partition? Is it practical, given the above scenario? And if it's not possible, barring buying another computer, can anyone suggest a best-of-all-worlds setup (the two worlds being performance, sandboxing, and running in parallel) for the above scenario? Thanks in advance.

• Virtual IPv6 Network between VirtualBox VMs

  - by Ben

  I'm trying to create a virtual IPv6 network as a test environment. I have 5 VirtualBox VMs (Ubuntu Server) with network adapters using host-only networking. You can imagine them being connected in series and every machine connects 2 subnets. I want to ping the last machine from the first one: On: 2001:db8:aaaa::100 I want to ping 2001:db8:dddd::101 (Note: there is no cccc network in between) Only static configuration and routes are used: /etc/network/interfaces auto eth0 iface eth0 inet6 static address 2001:db8:aaaa::100 netmask 64 /etc/network/interfaces auto eth0 iface eth0 inet6 static address 2001:db8:aaaa::101 netmask 64 auto eth1 iface eth1 inet6 static address 2001:db8:bbbb::100 netmask 64 up ip -6 route add 2001:db8:dddd::/64 via 2001:db8:bbbb::101 dev eth1 down ip -6 route del 2001:db8:dddd::/64 via 2001:db8:bbbb::101 dev eth1 I thought there might be some automatic route discovery going on. Anyway, ping6 2001:db8:dddd::100 will not work from aaaa::100 When I add the route: ip -6 route add 2001:db8:dddd::/64 via 2001:db8:aaaa::101 it will work. But the next interface in the same network dddd::101 is not reachable. How could that be? There is a machine with an interface bbbb::101 and another dddd::100 and I can ping the latter one, but the machine connected to it, dddd::101 not?? I also have also turned on forwarding. Any ideas?

• Apache Virtual Host with directory aliases

  - by brechtvhb

  I'm trying to set up a dynamic virtual host in apache with a directory alias pointing to a difirent path for every domain. Here's what I'm trying to achive. Say I have 2 domains: * www.domain1.com * www.domein2.com I want both to point to the same index.php file (C:/cms/index.php). Now the hard part ... I want directories or certain file types to point to a diffirent path for each domain. Example: * www.domain1.com/layout -> C:/store/www.domain1.com/layout * www.domain2.com/layout -> C:/store/www.domain2.com/layout * www.domain1.com/image.png -> C:/store/www.domain1.com/image.png * www.domain2.com/image.png -> C:/store/www.domain2.com/image.png However the admin directory should point to the same path again for all sites * www.domain1.com/admin -> C:/cms/admin * www.domain2.com/admin -> C:/cms/admin Is there a way to achieve this kind of behaviour in apache 2.2 without having to create a virtualhost entry for each new domain?

• Xen virtual host can reach some sites but not others

  - by Tun H S Lee

  Okay, this is killing me. Debian Squeeze, Xen 4.0, brand new install. No iptables rules whatsoever except for the ones added by the default xen bridge script. Dom0 can reach the entire world, no problems. DomU can receive packets from some hosts, but not from others. For instance, if I ping Host A, it works fine. If I ping Host B, the DomU reports 100% packet loss. The hosts are random, but consistent (even after reboots). I can see no pattern to why some work and others don't. In fact, in some cases, different virtual hosts on the same server (an other server at a different data center) are divided; some work and others do not. I can reboot (DomU or Dom0 too) and the same hosts will work or fail as before. If I tcpdump on the Host B while pinging from the DomU, everything looks fine. It sees the echo request coming in and says it's sending one back. However, if I tcpdump peth0 on the Dom0, it never sees the echo reply. Any ideas what could be happening? I'm tearing my hair out here.

• virtual host settings fail on multiple sites

  - by Ricalsin

  Wow. I'm puzzled. On my ubuntu system I've setup an apache2 server and configured three virtual hosts in the /etc/apache2/sites-available directory. a2ensite to symbolic link the sites-enabled. The first two work great; a simple url of localhost.mysitenames.com works great for the first two sites, both finding their DocumentRoot and Directory paths. The third always generates a Bad Request (Invalid Hostname) response. No server error.log as it never hits it. I've copied/pasted the working vhost files, made the minor changes to the ServerName, DocumentRoot and Directory and the same problem persists. I always "sudo /etc/init.d/apache2 restart" whenever I make a change. I've cleared the browser cache as well. No love. There's not a limit to the number of sites you can host, right? My goal was a localhost development environment with the expectation I can run any number of websites locally before pushing them to a live server. Any thoughts on how to debug this? Or, just a simple solution I am missing?

• Virtual machine shows no network adapter

  - by Logman

  I had a an old Lotus/Domino server (R5), I just virtualized. It ran Windows 2000 server. I had to use Vmware Converter v3.x to create the vm because it was the only one I could find that could actually do a Win2k machine that had no service packs. It was just put out to pasture a couple months ago, so it isn't being used except to store the old email for archiving. It took a bit of work to get it onto the Win2008R2 servers hyper-v but I got it there. Problem now, is that the network adapter didn't show up. I could not install the guest additions because it needed sp4 + on win2k... so I installed sp4 onto the vm guest. Everything seems fine except the network adapter still isn;t showing up in device manager. NOthing. Now this server had an external ip, and I did not want it to be put onto the internal virtual network. I am going to use a dedicated adapter on the host (hyper-v server) if that matters... but this shouldn't matter if the the guests network adapter doesn't show at all. Thoughts?

• Virtual host Alias not routing properly

  - by Jacob

  I apologize if this question has been asked many times in the past. I am not 100% sure of the exact cause of my issue and am out of google magic right now. Basically I have a virtual host file setup with an Alias record that points to a different directory other the document root. It basically looks like this <VirtualHost *:80> ServerName iBusinessCentral.com ServerAdmin [email protected] DocumentRoot /var/www/marketingsites/ ServerAlias iBusinessCentral.com *.iBusinessCentral.com Alias /unsub "/var/www/unsub/site_index/" </VirtualHost> When I navigate to ibusinesscentral.com/unsub/?randomquerystring I am directed to the correct folder. If I remove the query string and navigate to ibusinesscentral.com/unsub/ I am taken to the directory in the document root. The unsub directory is a zend application and I need to be able to navigate to different url paths like ibusinesscentral.com/unsub/unenroll?querystring I have tried using AliasMatch instead of Alias. I have also tried adding a slash after the unsub portion of the Alias record, and have not had any luck to this point. Thanks in advance for any assistance

• Creating an IIS 6 Virtual Directory with PowerShell v2 over WMI/ADSI

  - by codepoke

  I can create an IISWebVirtualDir or IISWebVirtualDirSetting with WMI, but I've found no way to turn the virtual directory into an IIS Application. The virtual directory wants an AppFriendlyName and a Path. That's easy because they're part of the ...Setting object. But in order to turn the virtual directory into an App, you need to set AppIsolated=2 and AppRoot=[its root]. I cannot do this with WMI. I'd rather not mix ADSI and WMI, so if anyone can coach me through to amking this happen in WMI I'd be very happy. Here's my demo code: $server = 'serverName' $site = 'W3SVC/10/ROOT/' $app = 'AppName' # If I use these args, the VirDir is not created at all. Fails to write read-only prop # $args = @{'Name'=('W3SVC/10/ROOT/' + $app); ` # 'AppIsolated'=2;'AppRoot'='/LM/' + $site + $app} # So I use this single arg $args = @{'Name'=($site + $app)} $args # Look at the args to make sure I'm putting what I think I am $v = set-wmiinstance -Class IIsWebVirtualDir -Authentication PacketPrivacy ` -ComputerName $server -Namespace root\microsoftiisv2 -Arguments $args $v.Put() # VirDir now exists # Pull the settings object for it and prove I can tweak it $filter = "Name = '" + $site + $app + "'" $filter $v = get-wmiobject -Class IIsWebVirtualDirSetting -Authentication PacketPrivacy ` -ComputerName $server -Namespace root\microsoftiisv2 -Filter $filter $v.AppFriendlyName = $app $v.Put() $v # Yep. Changes work. Goes without saying I cannot change AppIsolated or AppRoot # But ADSI can change them without a hitch # Slower than molasses in January, but it works $a = [adsi]("IIS://$server/" + $site + $app) $a.Put("AppIsolated", 2) $a.Put("AppRoot", ('/LM/' + $site + $app)) $a.Put("Path", "C:\Inetpub\wwwroot\news") $a.SetInfo() $a Any thoughts?

• Mac gcc non-virtual thunk error

Now after googling the issue the first thing to try is changing the optimization setting, which I did... and no dice. Some link error. So these virtual functions are initially defined in GDragDropTarget, and GWindow's inheritance looks like this: class LgiClass GWindow : public GView #ifndef WIN32 , public GDragDropTarget #endif (LgiClass being for __declspec export/import on win32) Any ideas on what to try next? Maybe I need to provide more info.

• Virtual properties duplicated during serialization when XmlElement attribute used

  - by Laramie

  The Goal: XML serialize an object that contains a list of objects of that and its derived types. The resulting XML should not use the xsi:type attribute to describe the type, to wit the names of the serialized XML elements would be an assigned name specific to the derived type, not always that of the base class, which is the default behavior. The Attempt: After exploring IXmlSerializable and IXmlSerializable with eerie XmlSchemaProvider methods and voodoo reflection to return specialized schemas and an XmlQualifiedName over the course of days, I found I was able to use the simple [XmlElement] attribute to accomplish the goal... almost. The Problem: Overridden properties appear twice when serializing. The exception reads "The XML element 'overriddenProperty' from namespace '' is already present in the current scope. Use XML attributes to specify another XML name or namespace for the element." I attempted using a *Specified property (see code), but it didn't work. Sample Code: Class Declaration using System; using System.Collections.Generic; using System.Xml.Serialization; [XmlInclude(typeof(DerivedClass))] public class BaseClass { public BaseClass() { } [XmlAttribute("virt")] public virtual string Virtual { get; set; } [XmlIgnore] public bool VirtualSpecified { get { return (this is BaseClass); } set { } } [XmlElement(ElementName = "B", Type = typeof(BaseClass), IsNullable = false)] [XmlElement(ElementName = "D", Type = typeof(DerivedClass), IsNullable = false)] public List<BaseClass> Children { get; set; } } public class DerivedClass : BaseClass { public DerivedClass() { } [XmlAttribute("virt")] public override string Virtual { get { return "always return spackle"; } set { } } } Driver: BaseClass baseClass = new BaseClass() { Children = new List<BaseClass>() }; BaseClass baseClass2 = new BaseClass(){}; DerivedClass derivedClass1 = new DerivedClass() { Children = new List<BaseClass>() }; DerivedClass derivedClass2 = new DerivedClass() { Children = new List<BaseClass>() }; baseClass.Children.Add(derivedClass1); baseClass.Children.Add(derivedClass2); derivedClass1.Children.Add(baseClass2); I've been wrestling with this on and off for weeks and can't find the answer anywhere.

• Dojo dialog, the iPad and the virtual keyboard issue

  - by Chris Butler

  Recently, I have been working on a project where the interface should work for desktop and tablets (in particular the iPad). One issue I am coming across is with a Dojo dialog on the iPad when text entry is taking place. Basically here is what happens: Load Dojo interface with buttons on iPad - OK Press button (touch) to show dialog (90% height and width) - OK Click on text box (touch) like DateTextBox or TimeTextBox - OK, the virtual keyboard is opened Click the date or time I want in the UI (touch) - OK, but I can't see all of the options since it is longer than the screen size... Try to scroll down (swipe up with two fingers or click 'next' in the keyboard) - not OK and the dialog repositions itself to have it's top at the top of the viewport area. Basically, the issue is that the dialog keeps trying to reposition itself. Am I able to stop dialog resizing and positioning if I catch the window onResize events? Does anyone else have this issue with the iPad and Dojo dialogs? Also, I found this StackOverflow topic on detecting the virtual keyboard, but it wasn't much help in this case... http://stackoverflow.com/questions/2593139/ipad-web-app-detect-virtual-keyboard-using-javascript-in-safari Thanks!

• How do I add IIS Virtual Directories and arbitrary files in TFS Solution

  - by chriscena

  We have a web portal product from which we customize portals from customers. We use the precompiled web app and create a virtual directory (vd) where the customization resides. In addition to this we do some changes web.config in the web app folder. We would obviously like to keep these customizations under TFS source control. When I try to add the precompiled web app (which I don't want to add to source control), a warning tells me that the vds cannot be added. If I only add the folder that is referenced to by the vd, I lose the references to assemblies in the precompiled web app. My questions are: How do I structure a solution for adding IIS (sub application level) virtual directories and still retain the references to assemblies? Is it possible to add other directories/files from the web application level (like App_Theme, web.config etc.) to the solution? Since we already use Visual Source Safe, we have established a tree structure for each customization project: Project Root | |-Custom Sql | |-Custom Portal Files (which is added as a virtual directory) | |-Other Customizations I could probably do a lot of this manually through the source control explorer, but I'd like to have everything done through a solution. I've followed the instructions using this article: http://msdn.microsoft.com/en-us/library/bb668986.aspx, but this doesn't address the exact problem that I have. Oh, and we are currently using Visual Source Safe for portal customizaton, but are eager to make the move to TFS. TIA

• SDL (And Others) Virtual Key Input

  - by David C

  Today I set up the input in my application for all the different keys. This works fine except for virtual keys, for example, caret or ampersand. Keys that normally need shift to be got at. Using SDL these virtual keys don't work. As in they do not register an event. if (event.type == SDL_KEYDOWN) { switch (event.key.keysym.sym) { case SDLK_CARET: Keys[KeyCodes::Caret] = KeyState::Down; break; case SDLK_UP: Keys[KeyCodes::Up] = KeyState::Down; break; default: break; } I am absolutely sure my system works with physical keys like Up. The program queries a keystate like so: if (Keys[KeyCode] == KeyState::Down) { lua_pushboolean(L, true); } else { lua_pushboolean(L, false); } KeyCode is passed in as an argument. So why are virtual keys, or keys that need shift to get at not working using SDL's KeyDown event type? Is more code needed to get to them? Or am I being stupid?

• How do virtual destructors work?

  - by Jack

  I am using gcc. I am aware how the virtual destructors solve the problem when we destroy a derived class object pointed by a base class pointer. I want to know how do they work? class A { public: A(){cout<<"A constructor"<<endl;} ~A(){cout<<"A destructor"<<endl;} }; class B:public A { public: B(){cout<<"B constructor"<<endl;} ~B(){cout<<"B destructor"<<endl;} }; int main() { A * a = new B(); delete a; getch(); return 0; } When I change A's destructor to a virtual function, the problem is solved. What is the inner working for this. Why do I make A's destructor virtual.

• How to filter the jqGrid data NOT using the built in search/filter box

  - by Jimbo

  I want users to be able to filter grid data without using the intrinsic search box. I have created two input fields for date (from and to) and now need to tell the grid to adopt this as its filter and then to request new data. Forging a server request for grid data (bypassing the grid) and setting the grid's data to be the response data wont work - because as soon as the user tries to re-order the results or change the page etc. the grid will request new data from the server using a blank filter. I cant seem to find grid API to achieve this - does anyone have any ideas? Thanks.
