• Upgrade of Ubuntu 8.10 distribution fails due to missing packages

  - by Tim

  I have a server that I've forgotten to upgrade for ages, which is still running Intrepid (8.10). I'd like to upgrade it to a newer version of the distribution, so that I can get security patches etc. I found some instructions that tell me to install the package update-manager-core. I tried the following: $ sudo apt-get install update-manager-core but this fails since some of the necessary packages can't be found: ... Err http://archive.ubuntu.com intrepid/main python-apt 0.7.7.1ubuntu4 404 Not Found [IP: 91.189.88.40 80] Err http://archive.ubuntu.com intrepid-updates/main update-manager-core 1:0.93.34 404 Not Found [IP: 91.189.88.40 80] Failed to fetch http://archive.ubuntu.com/ubuntu/pool/main/p/python-apt/python-apt_0.7.7.1ubuntu4_amd64.deb 404 Not Found [IP: 91.189.88.40 80] Failed to fetch http://archive.ubuntu.com/ubuntu/pool/main/u/update-manager/update-manager-core_0.93.34_amd64.deb 404 Not Found [IP: 91.189.88.40 80] ... I know that Intrepid is no longer supported, and so I guess some of the necessary files may no longer be maintained. But this seems rather unhelpful: I can't upgrade because it's too old, and the only way to fix this would be to upgrade it. Is there a way round this? Is something else wrong?

• Can I have a single solid state drive and a RAID array on the same machine? [closed]

  - by jaminto

  Hi- To summarize, i'm looking to use a single solid state drive as my primary drive, and two conventional sata drives in a RAID 1 configuration for data. I am trying to install 64-bit Windows 7 onto this configuration. Is this possible? Here are the details: I built a desktop that has been running 64-bit Vista on two 500Gb in a RAID 1 array for a few years. I just purchased an Intel X25-M 80Gb Sata Solid-State Drive, and was planning on using this a my primary drive, and keeping the RAID 1 array as my data drive. I added the SSD drive and in the RAID setup, configured it as a RAID 0 array of only one disk. Then, I tried to do a clean install of windows 7 64-bit, but got stuck in the "Missing driver for CD/DVD drive" black hole of selecting driver files and Windows telling me that i don't have the appropriate driver for my hardware. The missing hardware is NOT a CD/DVD drive, since i'm installing off of my only CD/DVD drive. Plus at one point i was able to point it at a driver for my raid controller, and then my hard drives magically showed up as browsable sources for finding drivers for some other unnamed device that setup couldn't recognize. After a few hours of trying drivers (this was a very slow process) i decided to reboot and look at the BIOS settings. I'm using an ASUS M2A-VM motherboard which has an ATI SB600 RAID controller on board. I switched the "On board SATA Type" setting from "SATA" to "AHCI" thinking that since AHCI is an Intel thing, this would help. Unfortunately, this abandoned my RAID configuration, and my previously mirrored drives are showing up as separate drives when i boot into my current windows installation. Am i trying to do the impossible here? Should i just buy a separate SATA/RAID PCI card and plug the SSD into that? Any help would be greatly appreciated.

• Removing expired self-signed certificate in IE9 (created with IIS7.5)

  - by Itison

  Over 1 year ago, I created a self-signed certificate in IIS 7.5 and exported it. I then installed it for IE9 (it may have been IE8 at the time), which worked fine until a year later when the certificate expired. I have put this off, but today I created a new self-signed certificate in IIS, exported it, and attempted to install it in IE9. The problem is that for whatever reason, IE cannot seem to forget about the old, expired certificate. Here's what I tried initially: Accessed my ASP.NET application and see the Certificate error. Clicked "View certificates". Clicked "Install Certificate" and then Next/Next/Finish. At this point, it says the import is successful, but it still only shows the expired certificate. I've tried simply double-clicking on the exported certificate on my desktop. Initially I chose to automatically select the certificate store, but then I tried it again and manually selected "Trusted Root Certification Authorities". I've also tried dragging/dropping the certificate over an IE window and clicking "Open". The process is then exactly the same as it is if I had double-clicked on the certificate, but I had hoped that this would somehow specifically tell IE to use this certificate. I tried opening MMC and with the Certificate snap-in, confirmed that the new certificate was added under "Trusted Root Certification Authorities". It was also under my "Personal" certificates (I guess this is where it goes by default). Nothing worked, so I went through every folder in MMC and deleted the expired certificate. I also deleted the expired certificate in IIS. Nothing has worked. Any ideas? I see no clear resolution and I can't seem to find any posts related to this issue.

• What needs to be considered when setting up for Linux Development? [closed]

  - by user123586

  I want to set up a box for Linux development. I have a working linux install with the usual toolchain and an IDE. I'm looking for advice on how to approach structuring accounts and folders for development. As the Perl folks say "There's always more than one way to do it." Left to my own devices, I'll come up with several unproductive ways of doing it before figuring out what an experienced Linux programmer would think obvious. I'm not looking for instructions to follow for a specific set of tools or a specific software package. Instead, I'm looking for insight into what decisions need to be made and how to make them, with understanding of the advantages and disadvantages of each individual choice. These are some of the questions that come up: Where to put sources Where to put built object files and libraries where to install what to set in environment variables what compiler flags matter and how do you manage them across several types of builds what configuration entries to make in an IDE how to manage libraries to support multiple environments how to handle different build versions such as debug vs release, or cross platform builds If you are an experienced Linux developer, the answers to these questions may seem trivial and obvious. I'd like to learn to make decisions about these questions that result in as little manual configuration as possible, given some existing sources, a particular IDE, or no IDE at all, a paticular set of development libraries etc. At this point you're probably thinking: Can you be more specific? Sure. But remember that I'm trying to learn how to think about this stuff, not just follow a recipie for a specific set of results. Example: Setup a project that uses CMake for some of its components, autogen.sh followed by configure for others and just configure for a few more: debug builds without an IDE debug builds in NetBeans debug builds in Eclipse debug build in Visual Studio all of the above with release builds for Linux, Mac and Windows. So... **What are your thoughts on an approach that works for all four? Do you have any advice on what to read?**

• Lenovo System Update Breaks Windows Live

  - by wolfvilleian

  Hey everyone, I've been racking my brain (and fingers from typing) trying to solve this issue to no avail. I have a Lenovo computer and I install their system update tool to install all my missing drivers. However after this tool is installed Windows Live 2011 breaks, it will no longer sign in giving error number 8e5e0247 all the solutions online haven't helped. It appears that a language setting somewhere gets set to en_ms, and I'm en_ca. My computer is running Windows 7 x64. When i try to sign onto messenger it gives an error that (with some research) means your locale or language is not supported, I've searched my computer for any reference to en_ms but find none. Also a few other things seem to have broken, When a UAC box comes up it is no longer able to identify the publisher of anything, and also the indexing service does not work (I'm not sure if the indexing issue is related, but the UAC issue happened right after installation), I had this issue before but I don't remember how I fixed it, I believe it had something to do with environmental variables. When it goes to sign in it gets as far as the "Loading contacts" then stops and goes back to the sign in screen. Has anyone seen this before? Thanks

• How to copy VirtualBox VDI contents to a partition and dual boot the OS from it?

  - by Calmarius

  I'm a Linux user but I keep a compressed Windows XP ISO with me on a pen drive for the case I absolutely need Windows to do something. This works in VirtualBox most of the time. But now I want to play some games, so I would like to run the Windows image natively. My computer don't have CD drive so cannot just burn the ISO and make an install normally. What I trying to do is moving the installed Windows image to a physical NTFS partition on my HDD and set up GRUB to let me dual boot it. I found many tutorials that deal with making VDI to physical drive. But they assume I want to overwrite my entire drive. Moving the raw disk image with dd to the partition resulted in a corrupt partition. I also tried the VMDK trick to use that empty partition and install the Windows on it. Although the text mode phase of the installation finishes without problems, the VM won't work, either crashes and keeps rebooting or just immediately or freezes (depending on how I created the VMDK, with -rawdisk /dev/sda3 or -rawdisk /dev/sda -partition 3).

• How to restrict windows service to X cores?

  - by Martinnj

  I'm currently trying ot figure out a decent/nice way of determening what core(s) a single service should run on, in Windows Server 2008. I'm aware that for procceses there is two ways to do it: set affinity through task manager after proccess is launched. use "start /AFFINITY 0x1" or similar bitmask However this does not seem to work very well with services. When i try to launch the exe that the service will also run (the one that needs restriction) it just spawns a new commandline (and starts the process) but the process terminates shortly after. Does anyone here know how to do a similar trick for services? It is not important what core it is running on, it just needs to be restricted to only one. And preferably it should be something that can be automated, so we do not have to interfere when there is a server restart.

• How to use ccache selectively?

  - by Anonymous

  I have to compile multiple versions of an app written in C++ and I think to use ccache for speeding up the process. ccache howtos have examples which suggest to create symlinks named gcc, g++ etc and make sure they appear in PATH before the original gcc binaries, so ccache is used instead. So far so good, but I'd like to use ccache only when compiling this particular app, not always. Of course, I can write a shell script that will try to create these symlinks every time I want to compile the app and will delete them when the app is compiled. But this looks like filesystem abuse to me. Are there better ways to use ccache selectively, not always? For compilation of a single source code file, I could just manually call ccache instead of gcc and be done, but I have to deal with a complex app that uses an automated build system for multiple source code files.

• Internet compression proxy for low speed broadband?

  - by user23150

  I live in a rural location, using high-latency wireless off a local ISP's tower. My speed tests vary day to day, but I can get around 1Mb up/down. The problem is, I work with large files, uploading and downloading (HD videos, development software, etc.). It can be painful to wait sometimes. Plus I do some side contract game development, and it can be very difficult to playtest with other developers (200ms ping is a good day for me). Now, obviously it's not going to be easy to solve the latency problem without different wireless hardware. But speedwise, I am wondering if I can use some kind of compression technology on a proxy. For instance, my work computer has full access to a 26Mb down, 10Mb up connection, that is totally unused at night and the weekends. If I could run some kind of compression technology on our server, and use it as a proxy to route to my home computer, I could stand to gain some major speed. I realize that by bogging down a system with compression, I could potentially lose whatever speed gain I had. But the proxy server is a quad core xeon, and the receiving computer is a pretty decent i7 computer, so that shouldn't be a concern. I found http://toonel.net/ but it seems more geared toward very slow narrowband users, like dial-up. Plus, I would prefer to just be able to point my browser to a proxy server, rather then install software on my client machine. EDIT I thought about my question a little more, and realize I am going to need to install software on my client in order to decompress, and possible compress (for uploading). That's not a huge deal.

• Revamping an old and unstable IT-solution for a customer?

  - by cmbrnt

  I've been given the cumbersome task to totally redo the IT-infrastructure for a customer's office. They are currently running Windows XP all over, with one computer acting as a file server with no control over which users have access to which files, and so on. To top it off, this file server also functions as a workstation, which means it gets rebooted every time the user notices some sluggish behavior or experiences problems with flash games. To say the least, this isn't working for them. Now - I've got a very slim budget, but I need to set up a new server, and I wish to run Windows Server 2008 on it. I also need the ability to access the network remotely via VPN. Would it be a good idea to install VMware ESXi 4.1 onto the new server, and then run Windows Server 2008 as well as a separate Debian install for openvpn on it? I don't like the Domain Controller for the future AD to also run a VPN-server, because of stability issues when something goes to hell with either of them. There will be no redundancy though. However, I'm not sure if there is something to gain by installing a VPN solution on the Windows Server itself, when it comes to accessing file shares on the network via VPN. I don't know how to enable users logging in via the VPN to access the remote files, since they will be accessing the network from their own home computers (which is indeed a really bad idea, but this is what I've got to work with). They won't be logged in to the windows Domain, but rather their home workgroups. I need to be able to grant access to files in certain directories based on the logged in AD-user, but every computer won't necessarily be configured to log into the domain. I'm not sure how to explain this in a good way, but I'd be happy to clarify if somethings not clear. Any help would be great, because I've got a feeling that I can't do this without introducing a bunch of costly new rules when it comes to their IT-solution. I'd rather leave that untouched and go on my merry way to the next assignment.

• Group Policy - Published software not upgrading

  - by VokinLoksar

  I'm testing this with mercurial MSIs, but it's the same for other packages. I've created a new group policy and added an old version of mercurial to User software installation as a Published package. On a Windows 7 client I install the package through Programs and Features. The installation works fine. Now, I would like to publish an updated version of mercurial. I create a new Published package. Under 'Upgrades' I configure it to replace (upgrade also doesn't work) the old version and mark this upgrade as 'Required'. The old package is not removed. The Windows 7 client is then restarted. When I log back in, I see a status message saying something like 'Removing managed software Mercurial ...'. There is no message about installation of the upgrade. If I look in Programs and Features, I can see the new version of mercurial listed. However, the actual mercurial directory under Program Files is missing. It's as though the installation recorded information about the MSI, but didn't actually install anything after removing the old version. As I mentioned, this isn't specific to mercurial. I've tried using other apps and have yet to find one that can be upgraded via a Published package. Using Assigned packages in Computer Configuration works without problems, but I would like this software to be optional rather than required. Ideas?

• How to avoid Remove-Item PowerShell errors "process cannot access the file"?

  - by Michael Freidgeim

  We are using TfsDeployer and PowerShell script to remove the folders ising Remove-Item before deployment of a new version. Sometimes the PS script failed with the error Remove-Item : Cannot remove item Services\bin: The process cannot access the file Services\bin' because it is being used by another proc Get-ChildItem -Path $Destination -Recurse | Remove-Item <<<< -force -recurse + CategoryInfo : WriteError: (C:\Program File..\Services\bin:DirectoryInfo) [Remove-Item], IOException FullyQualifiedErrorId : RemoveFileSystemItemIOError,Microsoft.PowerShell.Commands.RemoveItemCommand I’ve tried to follow the answer from PowerShell remove force to pipe get-childitem -recurse into remove-item. get-childitem * -include *.csv -recurse | remove-item ,but the error still happens periodically. We are using unlocker to manually kill locking application, (it’s usually w3wp), but I prefer to find automated solution. Another (not ideal) option is to-suppress-powershell-errors get-childitem -recurse -force -erroraction silentlycontinue Any suggestions are welcome.

• Fans still running after shutdown after upgrade to Windows 8

  - by docaholic

  I'm running into a really annoying issue after upgrading from Windows 7 to Windows 8. I first noticed it during the initial (clean) install; when the installer tried to reboot, my machine (an acer aspire 4755G) just hung after the initial shutdown. That is, after the screen turns off, the power lights and fans are still running, and the machine itself doesn't restart. (I let it sit for a good 15 minutes, and it still didn't change) I managed to do a hard reset (power button for 5 seconds) and the install finished, but every shutdown/restart has been like that. Interestingly enough, hibernate works just fine. I've looked at other solutions where it said to use the bcdedit /set disabledynamictick yes and that didn't work. I also turned off the "Fast Boot" option in the power settings menu. That didn't work either. So far, the only option is to do the hard shut down by holding down the power button, but that proves to be horribly inconvenient. Any ideas on what's going on here?

• Force Installing a Radeon HD 2100 on Windows 8

  - by Click Ok

  I'm trying force installing a Radeon HD 2100 on Windows 8. I've found that link from AMD with the drivers for Windows7: http://support.amd.com/us/gpudownload/windows/legacy/Pages/legacy-radeonaiw-vista64.aspx I know too that AMD will stop support Radeon HD 400 and older: http://www.techspot.com/news/48321-amd-drops-windows-8-support-for-radeon-hd-4000-and-older.html Now, let's go to the problem. If I try install the 12.6 driver, Windows will stick with the "basic display adapter", and this is bad for 3d games like Minecraft, that runs really slow now compared with the previous Windows7 installation. Forcing install the catalyst driver can help to fix it. So, I follow that steps: Extract the Catalist Driver (C:\AMD\Support\12-6-legacy_vista_win7_64_dd_ccc_whql) Right click the "basic display adapter" on device manager, and "update driver" Search on PC I will choose the driver "With Disk" "C:\AMD\Support\12-6-legacy_vista_win7_64_dd_ccc_whql\Packages\Drivers\Display\W76A_INF" There is a big list of drivers and the nearest driver to HD 2100 is "Radeon HD 2350 Series" My questions: Why isn't "Radeon HD 2100 Series" listed? (or Where is it listed?) In theory it must be listed" The first link above show that "This article applies to the following configuration(s):" (...) "AMD Radeon HD 2000 Series" Am I doing something wrong?

• Trouble with Remote Desktop pulling through printers. Drive Redirection works, and the ports created but not the printers

  - by Windex

  I've run out of things to look into. All the support documents have been gone through and still provide no resolution. I've checked the service permissions, (sc sdshow spooler) they all match up with other systems and what is output on the support documents. I'm nearly positive that the issue can't be permissions anyway as the software requires all users to be an administrator, so all users are a local administrator. (I haven't looked into why yet but its on the list, I was just recently brought into this team and we've put procedures in place for quick recovery.) We've applied hot fixes relating to RDS and printing, though I'm not sure which ones they were. I've combed through group policy and no where is printer redirection disabled. It's setup with all default values regarding the use and redirection of printers and a quick install of W2k8 R2 shows that it works by default. This dev install was joined to the same domain, placed in the same OU, shows the same policies applied, etc, etc, etc, The server generates all the correct redirected ports but no printers are created. It will also redirect drives without issue, this would seem to rule out the usermode service that handles redirects being broken. No events are logged related to any of the events and there are no events from the TerminalServices-Printer source. There were local printers setup. I didn't think it would mattter but as I was running out of ideas I tried deleting them all with no change. The TS was configured for the software it will be running before we checked out the redirection of printers so the other team responsible to setting up new servers wants to find a fix instead of reloading a new server. I'm not sure where or what else to look for. Any ideas?

• Getting PAM/user info into php - something like Net_Finger instead of a db?

  - by digitaltoast

  I've got a very small user group who just need to login, upload, check and then move specific files to a different area when ready. Right now, I use the nginx PAM auth module to log them in against their unix accounts. As their login is their home directory, I've already got the info to send the uploads to the right area - one line of php and no database needed. But I'm maintaining a separate DB just so PHP can welcome them, grab their email and send them an email when processed. Yes, sure I could use nosql or sqlite instead so as to not need a whole mysql install. But it occurred to me that as I've got all these blank user fields for phone numbers I could populate with any data, that I could use something like php's Net_Finger. Which failed for me with: sudo pear install Net_Finger Starting to download Net_Finger-1.0.1.tgz (1,618 bytes) ....done: 1,618 bytes could not extract the package.xml file from "/build/buildd/php5-5.5.9+dfsg/pear-build-download/Net_Finger-1.0.1.tgz" Download of "pear/Net_Finger" succeeded, but it is not a valid package archive Error: cannot download "pear/Net_Finger" At which point I thought I'd stop, and take a ServerFault reality check - is this a really bad/dangerous/stupid idea just to stop me having to maintain details in two places rather than one? It there a better way? Googling shows that it's not an oft-asked thing, so perhaps with good reason?

• ESX 3.5 refuses to update

  - by Speeddymon

  I have a set of ESX 3.5 servers in 2 different datacenters. One is DR, one is production. They are on the same vlan and so I can access any of them on the private network from my vCenter server. Last month, as a learning experience (I hadn't dealt with ESX much before), I updated the DR server. Other than finding out that a couple of bundles had to be installed manually in order to get the rest to install from vCenter, it went off without a hitch. Now, I'm trying to do the same for our production servers and it is not working. I've googled around for the error I get during scan, and investigate loads of different solutions (editing the integrity file, checking DNS, etc) -- I did install the 2 bundles that had to be installed manually already -- but scan from vCenter is just not working. Side note: I did just scan the DR server again and that scan works fine so shouldn't be a problem with vCenter that has cropped up recently -- it has to be something else. The error I get is: Patch metadata for (servername) missing. Please download updates metadata first. Failed to scan (servername) for updates. I'm all out of ideas on how to make this work, so any help would be hugely appreciated.

• Oracle Linux screen freezes during installation

  - by Fearless

  I was installing Oracle Linux 6.4 on a server, and the screen suddenly froze. Here were the previous steps: I put in the disk, clicked install, checked the disk (no errors), did pre-install setup (clock, root password, host+domain name, etc.), configured two 40GB hard drives in a RAID1 array (no swap, 3100mb encrypted raid partitions, ~100mb ext4 partition mounting to /boot, encrypted ext4 RAID device with mounting to /), selected packages, hit continue. The system did its short preinstall processes, then when to the main installation screen with the long status bar. The installer proceeded like always, but around package 250 out of ~1000, the screen suddenly went black with a text cursor in the upper left corner of the screen and the mouse cursor in its previous place. Neither cursor moved and the only thing that triggered a response was a ctrl-alt-delete that rebooted it. I have run this in VMs before without this issue. Memtest hasn't reported anything, and the media check went smoothly. The machine has supported Ubuntu server without issues before. Any ideas? I have tried booting after that, but the grub bootloader tries to find fd0 for some reason (I have no idea why it would search for the floppy disk). UPDATE My server successfully installed, but won't boot up. I think that, for some reason, it is still using the old bootloader from the previous installation. Any ideas on how to fix that?

• 2.6.9 Kernel on virtual server (non upgradable) - any expected problems?

  - by chris_l

  Hi, I'm considering to rent a virtual server (for me personally). The product I'm currently looking at offers IMO fair pricing, very good hardware etc. The only problem is, that I won't be able to do an upgrade to a newer kernel than 2.6.9 (running Debian Etch). Also, I can't install my own kernel modules. (The server runs with Virtuozzo, so as far as I understand it, it just does some chroot instead of a real virtualization (?)) I want to run GlassFish, Postgres, Subversion, Trac and maybe some other things on it. It will also have to employ a firewall, and provide OpenSSL for https. Ideally, it would also be able to do AIO (asynchronous IO), which could speed up some server I/O. Should I expect problems with that old kernel version, in conjunction with the software I want to install (I'd like to use current versions of the software)? One thing I already found out, is that you can't do everything with iptables, since some kernel modules are missing/things are not build into the kernel. GlassFish v3 appears to run fine at first glance. I was able to test the server for a few hours. Installing my whole setup wasn't feasible in that time, but what I can say is, that it's amazingly fast for an entry-level vserver, especially hard disk and network performance (averaging at ca. 400MBit/s). So if the kernel won't be a problem, I'd really like to take it. Thanks, Chris PS Exact kernel version: 2.6.9-023stab051.3-smp

• Windows XP Freezes

  - by Jim Fell

  Hello. I'm running a machine with Windows XP Professional 64-bit. Every so often, it will freeze for no apparent reason. That is, everything stops responding, except the mouse. I can move the mouse around, but I can't click on anything. Keyboard input is also not accepted/received when this problem occurs. The three-finger salute fails to bring up the Task Manager. Even pressing the power button on my computer fails to shut it down. The only way out of this that I have found is to hard-reboot the machine (i.e. pull power or hold power button in for 10 seconds). This problem was occurring on the system when it had all its updates and after a fresh install when not everthing was quite yet updated. I've run the Scandisk utility and the latest version Memtest86 that supports 64-bit architecture; neither found any errors. The last time this happened was on a fresh install of Windows. Only Nero Essentials, Avast antivirus (disabled), Firefox, and Spybot were installed. I was not running Nero, Firefox, or Spybot at the time, and Avast was disabled, so I'm pretty certain this is a Windows issue. Is anybody familiar with this problem or have any pointers? Thanks.

• Does programmable hardware exist to allow hardware to be programmed by computers?

  - by agentbanks217

  I am a programmer and I have never really dealt with the hardware of anything, only software. I want to start building things that I can control from my computer using programming. My question is are there such devices on the market that have a programmable interface or API? For example, I want to build a automated window blinds opening/closing device, and I would like to be able to control it from my computer e.g. writing an app or some code to schedule them when to open and close. I would like to know if there are any devices that can be programmed to do that (the computer part)? Thanks!

• Mac OS X change IP configuration automatically by location (by Wifi network)?

  - by Seppo Sade

  Can Mac OS X be setup to automatically configure its Airport interface with a static IP address when connected to a Wifi network with a certain name, and on all other Wifi networks use DHCP? Currently I'm using the "Locations" feature of the "Network" section in System Preferences to manually switch between two IP address setups. I have a "my static IP" setup, and a default "DHCP" setup. However this requires entering System Preferences to change the Location drop-down each time when switching locations. Can this be automated? Preferably this would be done without third-party software.

• Have some questions about setting up a VPN to my private cloud servers

  - by Pure.Krome

  I've got a number of Virtual Servers running at a pretty big Cloud provider. They are all running Windows 2008 R2. I have a CISCO ASA firewall in front of them. Currently, I've got all ports blocked except 80/443/21/3386 (for Remote Desktop). I asked to have a VPN enabled on the firewall and they said it's easy to do BUT I need to use the 3rd party Cisco software. Now, I don't want to get into a debate about it .. but we don't want to install anything extra on our -client- computers. We all use Windows 7 and we love using the built in VPN client to connect to other private LANS we have setup in other locations. So i'm wondering what options I have to create a VPN tunnel to our private cloud LAN? All our cloud servers are part of WORKGROUP, so there's no Active Directory .. nor do we want to install all that. Secondly, we know we can open up a firewall port - so any ports for starting a VPN is fine! Lastly, I was thinking of just using one of the existing servers as the VPN server (and using the Windows VPN software) .. but I'm not sure this is a good thing? Remember - we just want to use the baked in VPN software in Windows 7 .. which is PPTP or SSTP or L2TP/IPSEC. I would -LOVE- to use some free OSS software. For usernames/passwords? We'd probably just have one account .. like U:Hithere P:whatever.. so we don't need any hardcore account management, like Active Directory, etc. So does anyone have any ideas?

• What is a Dynamic way to Connect to a Virtual Machine's Webserver from its Host Machine? [closed]

  - by Jonnybojangles

  As a Web-Developer what is the most efficient (automated) way to connect to a Virtual Machine (VM) running a development webserver from it’s Host Machine (the machine running the VM) when you do not have control over the networks (home, Startbucks, work, etc) you are connected to? Currently I start my VM (a VirtualBox VM running CentOS), run ifconfig to determine the VM’s current IP. I then take that IP and map it my Host machine’s host file so that I can access the VM’s webserver from the Host. I feel that this is not an efficient way to connect to my VM’s webserver because each time I connect to a new network (a few times a day) I need to repeat the IP look up and host file update, and sometimes restart the VM's network service.
