• Access to local network machine

  - by Jirka Kopriva

  I have granted new setting from my domain provider. Domain with specific port is pointing on computer in local network (fixed ip) like: mydomain.com:87 -> 192.168.1.1 Local machine is running on win server 2008. Everything works fine on local network. But mydomain.com:87 is not working. Are there extra settings for win server to allow connection from outside? (Firewall is turned off while searching for working result.)

• VM connected to network but not to internet in VMware Player 6 on Windows 8.1 host

  - by user1257262

  So I am running Bitnami's MEAN stack in VMware Player 6.0.2 on Windows 8.1 and the VM connects just fine to the network: https://www.dropbox.com/s/xfdzohjuuepz52w/ifconfig.PNG However, I am having a great deal of trouble getting the VM to communicate with the internet. No matter what sort of action I take (even something as simple as apt-get update), the machine just sits there and eventually fails to connect. Here is my VM's Network Adapter configuration: https://www.dropbox.com/s/xfdzohjuuepz52w/ifconfig.PNG On my host Windows 8.1 computer, I actually have the VMware Bridge Protocol enabled but for VMware Network Adapters (VMnet1 and VMnet 8), but they are listed as having No Internet access in my Network and Sharing Center. I am not entirely sure if these adapters are relevant to connecting the VM to the internet, to be honest. This is the first time I have ever had an issue connecting a virtual machine to the internet. This problem is also happening with other VM's I am trying to run. Can someone tell me what I am doing wrong and how I can fix it?

• "Device not ready" on a network share in Windows 7

  - by user60689

  I have two computers C1 and C2 runing Windows 7 and both of them are members in a domain. On C1 I have an USB hard-disk which I shared for the users U1 and U2 giving them Read-Only permissions on the entire drive. However, even if I can see and browse the hard-disk localy (IOW from C1), from the other computer (C2) where I'm logged with U1, trying to access the C1's shared device, the C2's Windows 7 throws an error saying "Device Not Ready". Why? How can I fix this? PS: Tried to un-share and re-share again. No luck.

• How to forward http traffic through a specific network adapter.

  - by user18129

  i have the following scenario. Two laptops are connected via a router through the Ethernet ports. These two computers need to be able to communicate together. One computer also needs to access the internet through a different adapter (i.e. we will taking these two laptops two various sites where by the most common type of internet access will be wireless).In isolation all of the various adapters work fine (i.e. the internal network works fine, and the wireless connects to the internet). However,we try to turn on all of the adapters at the same time,the following occurs: If we bridge the two network connections together on the "Server" -The internet connection doesn't work through the wireless If we don't bridge the connections The internet connections don't work It seems like http traffic is trying to be sent through the Ethernet adapter (which of course is not connected to an internet connection). How can we solve this?

• Is it possible to host a web server from behind a NAT

  - by iamrohitbanga

  My PC is behind a NAT router that has a public IP address. If I want to host a website then I believe I need a domain name which I can purchase from some site which would pledge to resolve all DNS requests for that domain name and send the IP address of my NAT router (assuming I do not want to host my domain name on their servers). Now I want to host a web server on my computer. What changes should be done to the NAT router's configuration to forward all HTTP requests for example.com to my PC in the internal network. Is the above strategy correct? Is it commonly used?

• Ubuntu 11.10 very slow compared to Windows

  - by Patrick

  I'm new to Ubuntu/linux. Since my PC is very old and not very fast with Windows 7, I decided to give Ubuntu a try, so I downloaded and installed Ubuntu 11.10 today. When I first started it, I had bad 800x600 resolution and it was very slow and annoying. So I installed a driver for my graphic card and now everything looks very nice (1280x1024).But I think it's still far slower than Windows 7. I tried to run in Ubuntu like a few people suggested on the forum but if I log in I get a black screen saying something like "this video mode cannot be displayed". I get that same screen when booting Ubuntu btw, but after about 15 seconds it disappears and just starts Ubuntu. I also installed other drivers for my graphic card but everything stayed the same. I noticed that i.e. when I open Firefox or system settings it takes about 5 seconds till it opens (while Windows 7 takes under 1 second to start i.e. Chrome) and when I do this my CPU usage gets to 100% for a short time. Computer specs: Memory: 2GB RAM Processor: Intel Pentium 4 2.8GHz Graphics Card: Nvidia GeForce 6800 400MHz. I read on various forums that 11.04 works flawless on many PCs, where 11.10 is very slow. Should I install 11.04 or could anybody help me with this problem?

• Do you have to recreate workspaces after upgrading a TFS 2008 server to TFS 2010?

  - by Clara Oscura

  I am just reposting this thread from a MSDN forum since it seems to be unavailable. It was very useful when I was having trouble with my folder mappings after migrating to TFS 2010. Question: I opened VS2008 and connected it to the upgraded 2010 TFS server.  Upon clicking any of our Team Projects in source control explorer I get "Team Foundation Error - The workspace MYWORKSPACE;DOMAIN\MYUsername already exists on computer MYPCNAME." Answer: The same local paths on your machine are mapped to 2 different workspaces, one on the preupgrade server and one on the postupgrade server.  It's not safe to have multiple workspaces on different servers mapped to the same local paths b/c you could pend some changes while connected to one server, and the other server would have no idea what you did.  You should either delete your conflicting workspaces from one of the servers (if you don't need them on both), or test the new TFS instance from a new workspace (on different machine). If you want to test an existing production workspace on both servers, then yes, you will have to mess around with the workspace cache. You don’t have to delete the entire cache, you just need to run "tf workspaces /remove:* /server:<serverurl>" to clear the cached workspaces from a server (the command won't delete the workspaces), and possibly "tf workspaces /server:<server>" to refresh the workspace cache for a given server.  You will also have to do back up and restore the workspace before switching servers or your local files could be inconsistent.

• Lan DNS not working after reinstall of Ubuntu 13.10

  - by DrorCohen

  I upgrade my Ubuntu desktop to 13.10. When I say upgrade I mean installed on a new partition from scratch (old partition is available if To the problem: I'm trying to ping a host (Drobo-FS server) by it's host name. I get "Unknown Host". However pinging from another computer on the same lan - works fine (a laptop with 12.04 lts). for that matter every ping from the 13.10 to the local lan by hostname fails, ping with ip works. I don't have a local DNS server but somehow all the other computers in the network find each other by host name - only this new one fails... help appreciated...

• Can Grub be configured to remember the last OS you booted into?

  - by Matthew

  I typically have 2-3 OSes in my boot menu: Ubuntu 10.04 Windows 7 [Sometimes, a third option, such as Ubuntu 10.04 Netbook] If I am in an OS other than the default choice (Windows 7 in this case), and I reboot, Grub boots into Ubuntu 10.04. This shouldn't happen--when I reboot in Windows 7, I want to stay in Windows 7. Is there any way to configure Grub to remember my last choice, and boot into that? Alternatively, it would be even better if Grub only did this when I rebooted (not when I first turn the computer on). I realize this may not be possible, so I'd be happy with simple last-choice-remembering.

• Unable to log in due to freeze, occasional error message

  - by Xianlin Xiong

  I'm new to Ubuntu. And I have some problems now. I downloaded Ubuntu 11.10 and burned it onto a CD. Then I load it in my conputer, it's easy. But when I finished those and restarted the computer, the problem comes: After I choose to log in the Ubuntu system,the screen stays in pink, and it can't jump into (about 30 min), and then I have no choices but to press Ctrl+Alt+Del to reboot. Another time I choose Ubuntu to log in, it shows on the screen that "BusyBox v1.18.4 ...... built-in shell ...... initramfs". However the Live CD works very well. What’s more, there is a Windows 7 partition on the hard drive. (Windows 7 is also okay.) But I leave more than 20GB on the hard drive to Ubuntu. When I installed Ubuntu, I only made two partitions (swap and /). I don’t know where the problems happened and how to deal with them. And I hope someone can help me out with the troubles.

• Software to create a virtual parallel port in Windows XP?

  - by drknexus

  I am writing a program that will eventually be used on a computer with a physical parallel port and will need to set certain pins high or low in order to signal to an external device. However, the development laptop I am using does not have any physical parallel ports and is too low powered to run a virtual machine. Is there any option available that will create a virtual parallel port within Windows XP? Ideally it would include a debug mode that would allow me to see what values have been pushed out on the parallel port.

• What is the canonical approach to using a VCS right from a project's infancy?

  - by Anonymous -

  Background I've used VCS (mainly git) in the past to manage many existing projects and it works great. Typically with an existing project, I would check in each change I make to the code that either optimizes or changes the overall functionality (you know what I mean, in suitable steps, not every single line I change). Problem One thing I've not had so much practise at is creating new projects. I'm in the process of starting a new project of my own that will probably grow quite large, but I'm finding that there is a lot to do and a lot changing in the first few days/hours/weeks/the period up until the product is actually functioning in it's most basic form. Is there any point in me checking in each step of the process as I would with an existing project? I'm not breaking the project with changes I make since it isn't working yet. At the moment I've simply been using VCS as a backup at the end of each day, when I leave the computer. My first few commits were things like "Basic directory structure in place" and "DB tables created". How should I use a VCS when starting a new project?

• 11.10 system crashes for no apparent reason [closed]

  - by varanoid

  I'm relatively new to Linux, and while I know a fair amount about computers and programming, it certainly isn't my specialty. I have a dual boot with Windows 7, and it has been working very well for me until recently. Just randomly the computer will freeze. The last time I was smart enough to keep the System Monitor open when it happened, and it looks like at the time of freezing "bash" and a bunch of other processes that I don't recognize seem to have flooded the memory. So it looks like my memory is getting overloaded and this is what is crashing the system, but I honestly have no idea what could be doing it. Generally I have a bunch of programs running, but they don't take much RAM or CPU: Transmission, Libre Office Writer, Firefox, Empathy, and Banshee. Sometimes I also have Text Editor and Terminal open, but it crashes regardless. When it crashes, it seems that all of the programs are working fine but things like windows, the taskbar, and operations like Alt+Tab just stop working properly or at all. Sometimes the mouse and keyboard freeze and I have to power off manually. Other than that I don't know what the problem is. The only irregularity I've experienced is that I can't download "Debian package management system" even though other updates download fine.

• Windows XP not starting up anymore (BSOD)

  - by Richard

  When I tried to start my computer running Windows XP yesterday, as I turned on the screen it was stuck at the "Welcome" screen. I had to reset it. After that, I got stuck at the point where the BIOS should load the OS - I turn on the PC, the Motherboard and BIOS post message shows up, then the blinking "thing" in the top left corner shows up 2 seconds, then everything is black. After I let it run for some time in that mode, it automatically restarts. I'm writing this here from a Ubuntu 9.10 Live CD. What can I do to fix this? How can I find out what is wrong? I'm a programmer and okay with doing (very) advanced things in that terms, so if you know something just tell me and I'll try

• Moving to an outside Exchange provider - How to create new Outlook profile on multiple PCs?

  - by imagodei

  Following an acquisition we are switching from our local Exchange to an outside provider. I need to change account settings / create new profile so that users are able to access their new mailbox, and I hate the idea of doing it manually on every single client. I have tried quick and dirty solution with copying profile information from Registry on one computer to the other, hoping that I could fix user info later. Quite obviously, this didn't work: Outlook recognized the profile, I could select it at the application startup, but there the fun ends - the profile was corrupt. I couldn't change settings in Mail settings on Control panel, either. Didn't find any Group policy solution. Is there any application, script or other solution, that would help me save time commuting from one PC to the other and typing the same info over and over again?

• Identity in .NET 4.5&ndash;Part 3: (Breaking) changes

  - by Your DisplayName here!

  I recently started porting a private build of Thinktecture.IdentityModel to .NET 4.5 and noticed a number of changes. The good news is that I can delete large parts of my library because many features are now in the box. Along the way I found some other nice additions. ClaimsIdentity now has methods to query the claims collection, e.g. HasClaim(), FindFirst(), FindAll(). ClaimsPrincipal has those methods as well. But they work across all contained identities. Nice! ClaimsPrincipal.Current retrieves the ClaimsPrincipal from Thread.CurrentPrincipal. Combined with the above changes, no casting necessary anymore. SecurityTokenHandler now has read and write methods that work directly with strings. This makes it much easier to deal with non-XML tokens like SWT or JWT. A new session security token handler that uses the ASP.NET machine key to protect the cookie. This makes it easier to get started in web farm scenarios. No need for a custom service host factory or the federation behavior anymore. WCF can be switched into “WIF mode” with the useIdentityConfiguration switch (odd name though). Tooling has become better and the new test STS makes it very easy to get started. On the other hand – and that was kind of expected – to bring claims into the core framework, there are also some breaking changes for WIF code. If you want to migrate (and I would recommend that), most changes to your code are mechanical. The following is a brain dump of the changes I encountered. Assembly Microsoft.IdentityModel is gone. The new functionality is now in mscorlib, System.IdentityModel(.Services) and System.ServiceModel. All the namespaces have changed as well. No IClaimsPrincipal and IClaimsIdentity anymore. Configuration section has been split into <system.identityModel /> and <system.identityModel.services />. WCF configuration story has changed as well. Claim.ClaimType is now Claim.Type. ClaimCollection is now IEnumerable<Claim>. IsSessionMode is now IsReferenceMode. Bootstrap token handling is different now. ClaimsPrincipalHttpModule is gone. This is not really needed anymore, apart from maybe claims transformation (see here). Various factory methods on ClaimsPrincipal are gone (e.g. ClaimsPrincipal.CreateFromIdentity()). SecurityTokenHandler.ValidateToken now returns a ReadOnlyCollection<ClaimsIdentity>. Some lower level helper classes are gone or internal now (e.g. KeyGenerator). The WCF WS-Trust bindings are gone. I think this is a pity. They were *really* useful when doing work with WSTrustChannelFactory. Since WIF is part of the Windows operating system and also supported in future versions of .NET, there is no urgent need to migrate to the 4.5 claims model. But obviously, going forward, at some point you want to make the move.

• how can I get rid of duplicate administrators on 2 macbook pro's

  - by BCITY

  I got a new MacBook Pro (insurance payout) and passed my old one (previous generation MacBookPro 2008) on to a staff member whose MacBook Pro died. I used carbon copy to move my data to the new laptop but couldn't do the same with her move as the older Macbook wouldn't allow it as it was on an old OS. Ended up just migrating her software onto my old MBP. Now however, they both have the same admin identities and her computer is synching with my mobile me account. Can I change the administrator identity and save all her applications? I am hoping that I don't have to wipe and reinstall everything to change her computers identity.

• $DISPLAY dependent gtk themes

  - by Vlad Seghete

  I have a computer at home that I log into remotely. The "monitor" for it is a TV, so I want gtk applications to use a large font and icon theme, which I managed to do by editing the ~/.gtkrc-2.0 file and some other similar stuff. What I want to be able to do is have a separate theme for when I'm logging in remotely. The best way to explain is that I would like my gtk theme choice to be dependent on the X display that the application is started on. For example, if I start something on :0.0 then that is the TV and I want large fonts, but if I start it on localhost:10.0 I want to use a regular size font, because it will get rendered on my laptop screen. The elegant solution would be to have some sort of IF statement in the .gtkrc-2.0 file that checks the $DISPLAY variable and behaves accordingly. The problem is I can't find any documentation on control structures in .gktrc files, or if it's even possible to do that.

• How can I can delete a project in Aperture, but not in Flickr?

  - by jchatard

  I have a Macbook Air as my only computer ; I store my shots on Flickr. The size of the SSD doesn't allow me to keep all my RAW files on my laptop. So I publish the photographs I like in their final state on Flickr with the built-in feature of Aperture. When I hit delete on a project (in Aperture) the message clearly indicates that all photos synched to any service like Facebook, Flickr or any other will be deleted. How can I can around this without the hacky way of unlinking Aperture from Flickr before deleting the project?

• Little server for a little network: Asus TS Mini + Windows Home Server or other?

  - by microspino

  Hello, I'm building a little network with 4 computer a plotter, 3 printers an a HP Fax/Scan/Copy/Print machine. The network is connected to the web by a D-Link router/firewall. I would like to add little server to have file sharing (reachable via VPN from outside by a single user-road-warrior), automatic backups. I would like to avoid big electrics bills or, to say It in a green way, I would like to avoid useless power consumption made by a big server with hot-plug, Raid, double PSU because I don't need all this stuff. The server must work 24/7 and the budget is between 400€ and 1000€. I'm evaluating the Asus EEE Box (with XP), a TranquilPC (with XP), a FitPC (again with XP), and an Asus TS Mini (with Windows Home Server). I like the latter but since I'm Europe I don't know where I can buy It. Do you have any suggestion/experience to share with me about: which hardware do I have to buy ? which O.S. ?

• If a change the CPU, must I reinstall the OS?

  - by dag729

  Hi, as suggested by the title, I want to change CPU: actually I have two computers, one with Ubuntu running on an AMD Athlon 64 dual core 5200+ and the other with FreeBSD running on an AMD Sempron single core LE-1250. I would like to swap (I am not sure that this is the correct term...) the CPUs from one computer to the other one, that is take the dual core from the ubuntu pc and put it inside the freebsd pc and viceversa. The mobo is the same. Do you think I will encounter problems?

• Is anyone else having issues with opening app links on iOS6 iPad3?

  - by lindon fox

  Links to ios apps (to the app store) are not working for me on my iPad 3/iOS 6. I thought it was my code causing the problem initially, but then I tried it on an iPhone, and an older iPad 2 and they both worked. I looked into it further and it seems no links are working (that I can find). I have googled, but I have not found anything yet. Is there anyone else having this problem? Example: link - this link will work on my computer and phone, but not on my iPad3 running iOS6 - it will just bring up the app store app showing the main screen.

• Dual displays not working - NVidia - Ubuntu 12.04 - Second Monitor - Two Screens

  - by user75105

  Graphics Card: NVidia 460 GTX. Driver: NVIDIA accelerated graphics driver (version current) I have one DVI monitor, an old Dell LCD from 2005, and one VGA monitor, an Asus ML238H from 2010 whose HDMI port broke. The Asus is plugged into my graphics card's primary monitor slot and is the better monitor even though it is VGA but my computer defaults to the Dell. This happens when I boot as well; the loading screens, the motherboard brand image, etc. are all displayed on the Dell monitor until Windows loads. Then both monitors work. The same thing happened when I booted up Ubuntu 12.04 but I did not see the second monitor when the log-in screen popped up, nor did I when I logged in. I went to System Settings/Displays and my Asus monitor is not an option. I clicked Detect Displays and the Asus is not detected. I looked at the other questions regarding NVIDIA drivers and recalled my problems with Ubuntu a few years ago and decided to check the driver. I went to Additional Drivers to install the proprietary driver and it looks like it's installed and active but I'm still having this problem. There is another driver option, the post-release NVIDIA driver, but that does not fix the problem either. Also, under System Details/Graphics the graphics device is listed as Unknown, which might indicate that it is using an open source generic driver and not the proprietary NVidia driver. But under Additional Drivers it says that I am using the NVidia driver. Any help is appreciated.

• Black screen on Windows 7 right after opening Google Sketchup or Minecraft

  - by Aero

  I get a black screen on Windows 7 right after opening Google Sketchup or Minecraft. I presume there are other applications that cause this too - but I have not tried to open them. The window initially stops responding for a few seconds, before I get a black screen and my Skype call ends abruptly. I have tried waiting for a few minutes but nothing happens. I have to power down my computer and then boot it up again. This is becoming an annoyance, and I don't know what's causing it. Here are my specs, if it helps: My graphics card is an ATI RADEON XPRESS 1100. If you need any more info or if I've missed anything please ask. Thanks :-)

• Documenting software-updates semi-automatically in MacOS X by parsing log files?

  - by Martin

  I'd like to document changes I made to my computer (running MacOS 10.6.8) to be able to identify the sources of eventual problems. Mostly I install updates when a software notifies me about a newer version and offers me a dialog to download and install the update. Currently I'm documenting those updates "by hand" by noting in a text file, when I have e. g. installed a Flash-Player update or updated another 3rd party software ... I wonder if I could achieve that easier and semi-automatically by parsing system logfiles for certain texts like "install" and that way directly get the relevant information: what has been installed (Software and version) when has been installed where has it been installed/what has changed Is there a way to extract such information by a script from the existing logfiles?
