• VMRC equivalent for Hyper-V?

  - by Ian Boyd

  VMRC was the client tool used to connect to virtual machines running on Virtual Server. Upgrading to Windows Server 2008 R2 with the Hyper-V role, i need a way for people to be able to use the virtual machines. Note: not all virtual machines will have network connectivity not all virtual machines will be running Windows some people needing to connect to a virtual machine will be running Windows XP Hyper-V manager, allowing management of the hyper-v server, is less desirable (since it allows management of the hyper-v server (and doesn't work on all operating systems)) What is the Windows Server 2008 R2 equivalent of VMRC; to "vnc" to a virtual server? Update: i think Tatas was suggesting Microsoft System Center Virtual Machine Manager Self-Service Portal 2.0 (?): Which requires SQL Server IIS Installing those would unfortunately violate our Windows Server 2008 R2 license. i might be looking at the wrong product link, since commenter said there is a version that doesn't require "System Center". Update 2: The Windows Server 2008 R2 running HyperV is being licensed with the understanding that it only be used to host HyperV. From the [Windows Server 2008 R2 Licensing FAQ][4]: Q. If I have one license for Windows Server 2008 R2 Standard and want to run it in a virtual operating system environment, can I continue running it in the physical operating system environment? A. Yes, with Windows Server 2008 R2 Standard, you may run one instance in the physical operating system environment and one instance in the virtual operating system environment; however, the instance running in the physical operating system environment may be used only to run hardware virtualization software, provide hardware virtualization services, or to run software to manage and service operating system environments on the licensed server. This is why i'm weary about installing IIS or SQL Server.

• How to make Virtualbox, OpenVPN, and Win2008 Web R2 like one another?

  - by Aquitaine

  Back with web developer guy wearing net admin hat. Hopefully this is an easy one. We have two servers on a public network at a hosted facility. Server A is our public-facing web server and server B is our database server. Both are running Windows 2008 Server R2 Web Edition. We want Server B isolated from everything except Server A, such that anyone who has to connect to server B goes through the VPN on Server A. It's not perfect since we have no access to do this on the router side, but it's what we've got. We've set up VirtualBox and OpenVPN Access Server on Server A. It has one network interface set to 'NAT' mode, such that OpenVPN gets its IP at 10.0.2.x, and to connect to the OpenVPN interface, I go to the local IP for the Virtualbox network adapter, 192.168.56.x, which works as I configured the appropriate ports using VBoxManage. My question is, do I need to be using Bridged Networking and give the VPN server its own IP, or is there some way to tell the server (either Windows or the Virtualbox OpenVPN) that 'any public connection on the real external IP on port X should be directed to this internal LAN address of 192.168.1.x on port Y'? OpenVPN itself doesn't seem to be aware of the server's real external IP unless we put it in Bridged networking mode; is that necessary or advisable? We're without RRAS since this is Web edition, but I feel like what we're going for is pretty simple. Thanks! Aq

• Strange RDP / Remote Desktop problem

  - by John Landheer

  I'll try to be as specific as I can be: Server is running SBS 2008 R2 (with all updates) Server is connected to the internet Server has 2 NIC's, one is disabled Server is running RDP Service (accessible directly from the internet, I know, not as secure as it should be) Computers A and B are on the same local net. Computers A and B are both Windows 7. Users X and Y are both admins on the server Computer A can connect as user X to the server with mstsc Computer A can connect as user Y to the server with mstsc Computer B can connect as user X to the server with mstsc Computer B CANNOT connect as user Y to the server with mstsc! Error that username/password is incorrect. The last point is the problem, I get an authentication error. This used to work flawlessly for the last year. The server and desktops have been rebooted. EDIT: I tried: prefixing domain to the username prefixing the server computer name to the username change the password copy/paste the password from notepad to make sure it was correct I find it very strange.... EDIT: The computers are not on the same subnet as the server. The server is at my hosting provider. All computers as all users can reach the web app that is running on the server.

• Enabling Session State in SharePoint 2010?

  - by Steve Danner

  I have a web service built for SharePoint 2007 that I am trying to port to SharePoint 2010. This web service is dependent on session state to function properly, but so far, I have been enable to get session state to work at all in SharePoint 2010. This web service runs as its own web application under t he /_vti_bin virtual directory. I have tried all of the following with no luck: Ensured the "State Service" service application is running. Added the System.Web.SessionState.SessionStateModule http module to my application's web.config file. Added the System.Web.SessionState.SessionStateModule http module to my SharePoint root web.config file. Added <pages enableSessionState="true" /> to my application's web.config file. Added <pages enableSessionState="true" /> to my root web.config file. Additional Environment info: Visual Studio 2008 - SP1 .NET 3.5 - SP1 SharePoint 2010 - RC Windows Server 2008 R2 ASMX web service (not WCF) Had anyone had any luck getting a web application or web service to use session state in SharePoint 2010 yet? Thanks! Steve

• Make Python Socket Server More Efficient

  - by BenMills

  I have very little experience working with sockets and multithreaded programming so to learn more I decided to see if I could hack together a little python socket server to power a chat room. I ended up getting it working pretty well but then I noticed my server's CPU usage spiked up over 100% when I had it running in the background. Here is my code in full: http://gist.github.com/332132 I know this is a pretty open ended question so besides just helping with my code are there any good articles I could read that could help me learn more about this? My full code: import select import socket import sys import threading from daemon import Daemon class Server: def __init__(self): self.host = '' self.port = 9998 self.backlog = 5 self.size = 1024 self.server = None self.threads = [] self.send_count = 0 def open_socket(self): try: self.server = socket.socket(socket.AF_INET6, socket.SOCK_STREAM) self.server.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) self.server.bind((self.host,self.port)) self.server.listen(5) print "Server Started..." except socket.error, (value,message): if self.server: self.server.close() print "Could not open socket: " + message sys.exit(1) def remove_thread(self, t): t.join() def send_to_children(self, msg): self.send_count = 0 for t in self.threads: t.send_msg(msg) print 'Sent to '+str(self.send_count)+" of "+str(len(self.threads)) def run(self): self.open_socket() input = [self.server,sys.stdin] running = 1 while running: inputready,outputready,exceptready = select.select(input,[],[]) for s in inputready: if s == self.server: # handle the server socket c = Client(self.server.accept(), self) c.start() self.threads.append(c) print "Num of clients: "+str(len(self.threads)) self.server.close() for c in self.threads: c.join() class Client(threading.Thread): def __init__(self,(client,address), server): threading.Thread.__init__(self) self.client = client self.address = address self.size = 1024 self.server = server self.running = True def send_msg(self, msg): if self.running: self.client.send(msg) self.server.send_count += 1 def run(self): while self.running: data = self.client.recv(self.size) if data: print data self.server.send_to_children(data) else: self.running = False self.server.threads.remove(self) self.client.close() """ Run Server """ class DaemonServer(Daemon): def run(self): s = Server() s.run() if __name__ == "__main__": d = DaemonServer('/var/servers/fserver.pid') if len(sys.argv) == 2: if 'start' == sys.argv[1]: d.start() elif 'stop' == sys.argv[1]: d.stop() elif 'restart' == sys.argv[1]: d.restart() else: print "Unknown command" sys.exit(2) sys.exit(0) else: print "usage: %s start|stop|restart" % sys.argv[0] sys.exit(2)

• A declarative workflow does not start automatically after you install Windows SharePoint Services 3.

  - by ira

  That's the title of kb947284 actually. Recently I was involved in a Sharepoint project. I run into this problem where my workflow does not start automatically. If I run the workflow manually, it's just fine. I found kb947284. Apparently the cause of this problem is the installation of WSS 3 SP1. I did what it said in the Resolution section but it didn't work. The Resolution said to set the application pool account to use a different user account. What kind of different does it mean? What kind of user account will work? I changed the user account but both old and new account is in the same group of administrator for the server where SP is installed. Oh! I also found a copy of kb947284 and one comments stated there is already a hotfix (kb956057). I've read the issues that are fixed but could not find anywhere about this workflow problem. Could anyone please tell me how it's supposed to be done? Thanks in advance.

• Websockets through Stunnel is giving random bytes.

  - by user16682

  I have several servers set up for a web application that I am developing. One is a load balancing server, and I'm running a php WebSockets server on this balancer. The website that I am developing on uses ssl, so I have my WebSockets running through a wss uri connecting directly to the balancer, where I have set up stunnel4 to decrypt all traffic at a certain port and re-rout it to my php WebSockets server. This works fine when it comes down to connecting to my server. That's not the problem. The problem occurs when I try to send data to the server. Occasionally when I try this, stunnel does not appear to be decrypting the data properly. I get garbage characters in my termanal running the server: what appear to be completely random bytes. This can sometimes go on for several consecutive messages that I send before abruptly working again. It is very erratic and unpredictable. Sometimes I refresh the page, and all the messages work perfectly. Sometimes the WebSocket connects and I have to wait 5-10 seconds before any messages I send are interpreted properly by the server. Other times I can't send any messages at all, because they all end up as garbage. I believe this is a stunnel problem, but I am not certain. Does anybody have any experience with this? I would like a more predictable server if I can get it. Some more information: This occurs extensively in Chrome, not quite as much in FireFox, and never in Safari. The php server I am using is phpws http://code.google.com/p/phpws/ -- On the WebSocket connection, this server would sometimes detect that the header was only 1 byte in size, the first byte of the WebSockets header. I had to modify the server to flush the buffer ever time this occurred so that it would reliably connect.

• In Sharepoint I need to include a preview image for the screen of selecting layout for a new page.

  - by netadictos

  In Sharepoint 2007, I have created a layout. As you know when the user creates a page he chooses a layout from a listbox. When you select a different element in the listbox, there is a preview image that changes on the left. I thought this was controlled by the node PublishingPreviewImage in the xml of the layout. I have verified that the image exists in that place. It is not working. The code I use is: <File Path="TituloTextoCtrl.aspx" Url="TituloTextoCtrl.aspx" Type="GhostableInLibrary" IgnoreIfAlreadyExists ="TRUE"> <Property Name="PublishingPreviewImage" Value="~SiteCollection/_catalogs/masterpage/$Resources:core,Culture;/Preview Images/titulotextoctrl.png, ~SiteCollection/_catalogs/masterpage/$Resources:core,Culture;/Preview Images/titulotextoctrl.png" /> <Property Name="MasterPageDescription" Value="Plantilla Titulo+Texto+Control" /> <Property Name="ContentType" Value="Titulo+Texto+Control" /> <Property Name="PublishingAssociatedContentType" Value=";#Vialibre_ContentTypeGeneral;#0x010100C568DB52D9D0A14D9B2FDCC96666E9F2007948130EC3DB064584E219954237AF39005215cca003b74e479baa123eb1dc5702;#" /> </File>

• Bespoke Development or Leverage SharePoint With Web Parts etc?

  - by Asim

  Hi all, We are currently in the process of drawing up a solution for an existing client, creating a number of eServices. The client currently have MOSS 2007. The proposed solution is to use MOSS as the launching pad for the eServices… The requirement involves drawing up several online forms which provide registration facilities as well as facilitating a workflow of some sort. I have been told that the proposed solution requires complex web forms. Most are complex forms with parent child details that have multiple windows. The proposed solution is to do some bespoke development, developing ASP .NET forms. These forms would be deployed under the _layouts folder of the current MOSS portal, inheriting the master page design on the current site. I have been told that this approach make development and deployment more simple, as well has having ‘complete integration’ with MOSS. My questions are: Is this the best way to leverage SharePoint – it seems like the proposed solution is not leveraging MOSS at all..! I thought perhaps utilizing Web Parts would be better, but I have been told that this is more complex and developing more smarter intuitive UI is more difficult. Is this really the case? If not, what should be the recommended approach? We will be utilizing Ultimus as the workflow engine. However, I have been recommended K2 Workflows. Anyone used both/have any opinions on either? Many thanks in advance! Kind Regards,

• How can I set the default value for a custom "Number" field in SharePoint?

  - by UnhipGlint

  I created a custom field for a content type I am creating using the XML below. <field ID="{GUID}" Required="False" DisplayName="Likes" Name="Likes" Type="Number" SourceID="http://schemas.microsoft.com/sharepoint/v3"><default>0</default></field> The field is meant to be used as a counter of sorts, and will be incremented programmatically. But, I can't get the value to default to "0" when a new item is created. However, for some reason, when I create a new column manually using the Site Collection settings page and configure it to default to "0" it works as it should. So far, I've tried the following tactics: I removed the "default" element from the field definition, and set the "DefaultValue" attribute on the content type definition. I exported a definition for the manually-created, working column (using an Imtech STSADM tool). Then, I added it to my field definitions XML and modified the IDs so that I could add it to my content type. When I did this, it still didn't work, even though it was exported from a working column! Any idea why this isn't working for me?

• In Sharepoint, how do I update the name of a folder in a document library using the web service API?

  - by Jess

  I'm using the UpdateListItems method of the Lists web service, and I can update an item in just about any kind of list, and folders in non-document library lists, but I can't seem to update the name of a folder in a document library. I must use the web services API, as sharepoint is not local. If my update batch looks like this: <Batch OnError="Continue" PreCalc="TRUE" ListVersion="0" ViewName=""> <Method ID="1" Cmd="Update"> <Field Name="ID">2</Field> <Field Name="Title">MyUpdatedFolderName</Field> <Field Name="FileLeafRef">MyUpdatedFolderName</Field> </Method> </Batch> I get no exception but the name is unchanged. If my update batch looks like this: <Batch OnError="Continue" PreCalc="TRUE" ListVersion="0" ViewName=""> <Method ID="1" Cmd="Update"> <Field Name="ID">2</Field> <Field Name="Title">MyUpdatedFolderName</Field> <Field Name="BaseName">MyUpdatedFolderName</Field> </Method> </Batch> I get an error result that the list item could not be found. I know the list item is there. Anyone have any ideas?

• Create a new site programmatically and select parent site? (SharePoint)

  - by peter

  Hi, I am using the following code to create a new site: newWeb = SPContext.GetContext(HttpContext.Current).Web.Webs.Add(newSiteUrl, newSiteName, null, (uint)1033, siteTemplate, true, false); try { newWeb.Update(); } NewSiteUrl and newSiteName are values from two textboxes and on whichever site I use this code (in a web part) the new site will be a subsite to this site. I would now like to be able to select a parent site so that the new site can sit anywhere in the site collection, not just as a subsite to the site where I use the web part. I created the following function to get all the sites in the site collection and populate a drop down with the name and url for every site private void getSites() { SPSite oSiteCollection = SPContext.Current.Site; SPWebCollection collWebsite = oSiteCollection.AllWebs; for (int i = 0; i < collWebsite.Count; i++) { ddlParentSite.Items.Add(new ListItem(collWebsite[i].Title, collWebsite[i].Url)); } oSiteCollection.Dispose(); } If the user selects a site in the dropdown, is it possible to use that URL in newSiteUrl so decide where the new site should be? I don't get it to work really and the new site still becomes a subsite to the current one. I guess it has to do with HttpContext.Current? Any ideas on how I should do it instead? It's the first time I write custom web parts and the sharepoint object model is a bit overwhelming at the moment. Thanks in advance.

• Problem using Polar Irda device in Windows Server 2008

  I'm attempting to use the Polar IrDA device with Windows Server 2008 R2 x64. Although they dont make explicit drivers for it, I figured the Windows 7 x64 drivers would do. http://www.polar.fi/en/support/downloads?product=&category=Software&documenttitle=Polar+IrDA+USB+Adapter+drivers&document=/gip/PKBStoGIP.nsf/web_cat/C225742500419A8AC2257458003D3F40 The device has a yellow warning icon in Device Manager. Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19) Is there anything I can do about this?

• Challenges in multi-player Android Game Server with RESTful Nature

  - by Kush

  I'm working on an Android Game based on Contract Bridge, as a part of my college Summer Internship project. The game will be multi-player such that 4 Android devices can play it, so there's no BOT or CPU player to be developed. At the time of getting project, I realized that most of the students had already worked on the project but none of their works is reusable now (for variety of reasons like, undocumented code and design architecture, different platform implementation). I have experience working on several open source projects and hence I emphasis to work out on this project such that components I make become reusable as much as possible. Now, as the game is multi-player and entire game progress will be handled on server, I'm currently working on Server's design, since I wanted to make game server reusable such that any client platform can use it, I was previously confused in selecting Socket or REST for Game Server's design, but later finalized to work on REST APIs for the server. Now, since I have to keep all players in-sync while they make movements in game, on server I've planned to use Database which will keep all players' progress, specific for each table (in Bridge, 4 players play on single table, and server will handle many such game tables). I don't know if its an appropriate decision to use database as shared medium to track progress of each game table (let me know if there's an appropriate or better option). Obviously, when game is completed for the table, data for that table on server's database is discarded. Now the problem is that, access to REST service is an HTTP call, so as long as client doesn't make any request, server will remain idle, and consider a situation where A player has played a card on his device and the device requests to apply this change on the server. Now, I need to let rest of the three devices know that the player has played a card, and also update view on their device. AFAIK, REST cannot provide a sort-of Push-notification system, since the connection to the server is not persistent. One solution that I thought was to make each device constantly poll the server for any change (like every 56 ms) and when changes are found, reflect it on the device. But I feel this is not an elegant way, as every HTTP request is expensive. (and I choose REST to make game play experience robust since, a mobile device tends to get disconnected from Internet, and if there's Socket-like persistent connection then entire game progress is subject to lost. Also, portability on client-end is important) Also, imagining a situation where 10 game tables are in progress and 40 players are playing, a server must be capable to handle flooded HTTP requests from all the devices which make it every 56 ms. So I wonder if the situation is assumed as DoS attack. So, explaining the situation, am I going on the right track for the server design? I wanted to be sure before I proceed much further with the code.

• How do I set a static DNS nameserver address on Ubuntu Server?

  - by Aleks

  I am trying statically to set DNS server addresses in my Ubuntu server running as virtual machine. I followed all recommendations on official Ubuntu support pages but I simply cannot get rid of my ISP's DNS servers set by DHCP. I assigned br0 interface on my host machine static IP address and eth0 on VM to use Google DNS and my own local DNS running on the second vm by setting it in /etc/network/interfaces. Tried to fiddle with head base and tail files in /etc/resolvconf/resolv.conf.d/ and tried to shuffle interface-order in /etc/resolvconf/interface-order but when I restarted network service I got the ISP's DNS addresses back every time. Is there a way that I can disable resolvconf and set up my resolv.conf file manually as I always did on Red Hat? Or at can you tell me which hook script keeps putting ISP DNSs in resolv.conf? My ISP don't allow me to change DHCP settings on my router so I cannot do it that way. Why is such a simple thing such as setting DNS servers got so complicated???

• Why don't we use dynamic (server-side generated) CSS?

  - by ern0

  As server-side generated HTML is trivial (and it was the only way to make dynamic webpages before AJAX), server-side generated CSS is not. Actually, I've never seen it. There are CSS compilers, but they generate CSS files which can be used as static. Technically, it requires no special libraries, the HTML style tag should reference to the PHP(/ASP/whatever) templater script instead of the static CSS file, and the script should send out CSS content-type header - that's all. Does it have cache problems? I don't think so. The script should send out no-cache etc. headers. Is it problem for designers? No, they should edit the CSS template (as they edit the HTML template). Why we don't use dynamic CSS generators? Or if there's any, please let me know.

All the domU system disks are EXT4 and are created using snapshots of the same original template. 3 of them run perfectly, but one (called s-ub-02) keeps on being remounted read-only. A subsequent e2fsck results in a single "invalid extent" diagnosis: e2fsck 1.41.14 (22-Dec-2010) /dev/domu/s-ub-02-root contains a file system with errors, check forced. Pass 1: Checking inodes, blocks, and sizes Inode 525418 has an invalid extent (logical block 8959, invalid physical block 0, len 0) Clear<y>? yes Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 4: Checking reference counts Pass 5: Checking group summary information /dev/domu/s-ub-02-root: 77757/655360 files (0.3% non-contiguous), 360592/2621440 blocks The console shows typically the following errors for the system disk (xvda2): [101980.903416] EXT4-fs error (device xvda2): ext4_ext_find_extent:732: inode #525418: comm apt-get: bad header/extent: invalid extent entries - magic f30a, entries 12, max 340(340), depth 0(0) [101980.903473] EXT4-fs (xvda2): Remounting filesystem read-only I have created new versions of the system disk. The same thing always happens. This, and the fact that the disk is ultimately on a RAID1, leads me to preclude a hardware disk error. The only obvious distinguishing feature of this domU is the presence of nfs-kernel-server, so I suspect that. Its exports file looks like this: /exports/users 192.168.0.0/255.255.248.0(rw,sync,no_subtree_check) /exports/media/music 192.168.0.0/255.255.248.0(rw,sync,no_subtree_check) /exports/media/pictures 192.168.0.0/255.255.248.0(rw,sync,no_subtree_check) /exports/opt 192.168.0.0/255.255.248.0(rw,sync,no_subtree_check) /exports/users and /exports/opt are LVM2 volumes from the same volume group as the system disk. /exports/media is an EXT2 volume. (There is an issue where clients see /exports/media/pictures as being a read-only volume, which I mention for completeness.) With the exception of the read-only problem, the NFS server appears to work correctly under light load for several hours before the "invalid extent" problem occurs. There are no helpful entries in /var/log. All of a sudden, no more files are written, so you can see when the disk was remounted read-only, but there is no indication of what the cause might be. Can anyone help me with this problem? Steve
