• VPN ipsec tunnel from router to single windows server computer (gateway-to-host)

  - by Chris Miller

  Firstly, is this possible? The situation: 2 different ISP's. One has several servers and a firewall running. The other is limited to only one virtual server with one network card running windows server 2008r2. I need to set up a site-to-site style VPN using IPsec between the firewall of one ISP and the windows host on the other (gateway-to-host). This host has to run a SQL-Server that I can access from the other ISP's servers through the VPN tunnel. It seems looking at the RFC for IPsec that this should be possible using the features of Windows 2008, but I can't get it to work so far... It seems that I can't access any services running on the same computer or IP address used as the tunnel endpoint? Thanks Chris

• How to update a keyboard layout DLL on Windows?

  - by user87690

  Information about keyboard layout is stored in keyboard layout DLLs on Windows. One can make a custom layout using a tool like Microsoft Keyboard Layout Creator (http://msdn.microsoft.com/en-us/goglobal/bb964665.aspx). It creates the dynamical library and also an installer which places the DLL at a right place and also puts necessary information to registry so the layout can be used. Now my question. How can one update his custom layout? One could uninstall the layout and install the new version which effectively replaces the DLL file. However this alone doesn't work because it seems that the old copy of the DLL stays loaded somewhere and is used when one sets the layout instead of loading new version. So is there a way how to tell the system that its “keyboard layout cache” is invalid? Of course I could reboot the whole system but I'd like to avoid it as it's annoying and seems to be poor design to reboot whole system just to reload a DLL.

• NAT via iptables and virtual interface

  - by Alex

  I'm trying to implement the following scenario: One VM-host, multiple guest VMs, each one gets its own IP-address (and domain). Our server has only one physical interface, so the intended use is to add virtual interfaces on eth0. To complicate our situation the provider uses port-security on their switches, so I can't run the guest interfaces in bridged mode, because then the switch detects a "spoofed" MAC-address and kills the interface (permanently, forcing me to call the support, which I'm sure will get them a little bit angry the third time ;) ). My first guess was to use iptables and NAT to forward all packages from one virtual interface to another one, but iptables doesn't seem to like virtual interfaces (at least I can't get it to work properly). So my second guess is to use the source IP of the packages to the public interface. Let's assume libvirt creates a virbr0-network with 192.168.100.0/24 and the guest uses 192.168.100.2 as IP-address. This is what I tried to use: iptables -t nat -I PREROUTING --src public_ip_on_eth0:0 -p tcp --dport 80 -j DNAT --to-destination 192.168.100.2:80 That doesn't give me the intended results either (accessing the server times out). Is there a way to do what I'm trying to do, or even to route all traffic to a certain IP on a virtual interface to the VM's device?

• Sync Banshee library data.

  - by Dom

  I use Banshee to organise my music, I particularly like its scoring system and I have smart playlists based on it. However, I have two versions of my music library, one on each of my computers. As one of the computers is small I only have a favourite set of songs on that computer rather than my whole collection. The computers are not on a local network, but I do use Ubuntu One for file sharing between them. Is there any way I can synchronise song data (play count, score, skip count ...) and playlist data (including smart playlists that include songs based on this data) between the two computers? This would only be relevant of course for the songs that exist on both computers, the songs that exist on only one would need to be ignored. I did consider putting the library data file (I think it is .xml but I'm not sure) into the shared file and creating a symbolic link to it, but then I wouldn't be able to have a different set of songs on each computer. Thank you.

• Ubuntu via Wubi refuses to show up in boot menu

  - by Redandwhite

  I'm in this strange situation: I have 3 partitions, one for Vista (C), one for Windows 7 (D), and one 10GB partition (E). At least that's how my original OEM Vista partition sees them. The primary OS that I boot into everyday is Windows 7. The situation is that for some reason it sees the Windows 7 partition (its own) as drive C, the 10GB one as (D) and the Vista one as (E). I've successfully used the Wubi installation before on Vista, but now it simply doesn't work. Ubuntu just does not show up in the boot menu, no matter what I try to do. I'm running out of ideas. I heard it doesn't really play well with Windows 7 either. I set it to Vista compatibility mode and that didn't work, I also tried installing it from Vista itself and that didn't work either for some reason. Any ideas what I should try? If anyone is about to suggest EasyBCD, please underline the command-line instructions I'm gonna need to follow. Thanks.

• Preserve embedded album art when converting from .flac to .ogg

  - by Profpatsch

  I want to convert my archived .flac library to .ogg for daily use. Using find ./ -iname '*.flac' -print0 | xargs -0 -n1 oggenc -q6 on the root music folder and then deleting every .flac (having copies of them in archive) seems straight forward, after trying it with one file it worked and all of the tags were transfered, too, except for one: Embedded album art! I always prefer emedded covers over folder images, since I have some albums with varying covers. One possible solution is discussed here, but the script only works if the image is already extracted: Embed album art in OGG through command line in linux One possible solution I thought about was extracting album art from every song (not every song has one, though, and some even 2 or 3!), temporarily saving it and then using the script to include it into the finished .ogg. But then I want to increase the number of processes xargs runs simultaniously to save time, so the temp images need to have a distinct name. Is there a (linux) program that knows how to handle this? Or is there a finished script floating around somewhere? It would be nice if oggenc supported adding embedded coverart and it really is a shame, since these two formats should (in theory) share the same tag format. Edit: 15 days and noone even tries to answer. It’s funny, most of my questions don’t get answered. Too hard? Wrong SE site?

• Multiple servers vs 1 big server performace

  - by pistacchio

  Hi to all! My team of developers has suggested a server structure for an upcoming project we are developing. Our structure is "logical", meaning that the various logical components of the application (it is a distributed one) relies on different servers. Some components are more critical than others and will be subjected to more load. Our proposal was to have 1 server per component but the hardware guys suggested to replace the various machines with a single, bigger one with virtual servers. They're gonna use Blade Servers. Now, I'm not an expert at all, but my question to the guys was: so if we need, for example, 3 2GHz CPU / 2GB RAM machines and you give me 1 machine with 3 2GHz CPUs and 6 GB of RAM it is the same? They told me it is. Is this accurate? What are the advantages or disadvantages of both the solutions? What are the generally accepted best practices? Could you point out some URL reference dealing with the problem? Thank you in advance! EDIT: Some more info. The (internet / intranet) application is already layered. We have some servers on the DMZ that will expose pages to the internet and the databases are on their own machines. What we want to split (and they want to join) are some webservers that mainly expose webservices. One is a DAL that communicates with the database layer, one is our Single Sign On / User Profile application that gets called once per page and one is a clone of what seen on the Internet to be used on our lan.

• Formatting a memory stick with two partitions?

  - by Marius

  I have a 16GB memorystick which used to have a Linux partition. It therefore has two partitions; 2GB FAT32 and 14GB linux boot drive. The linux part stopped working, so I decided to reinstall it. But windows can't see that partition. I tried formatting the whole disk, but I can only format one partition (the FAT32). There seems to be no way to combine the two partitions into one big one, and there seems to be no way for windows to partition the large part of the memorystick to but Linux on it. In the windows partition manager, windows sees the large unused partition, and it let me delete it. But once I have deleted it, I'm not allowed to format it. Also I cannot delete or resize the small partition. So, to summarize: I have a memorystick with two partitons. Windows only sees one of them, and won't let me use the other one. I would like to combine the two partitions so I can install Linux on the memory stick again.

• Two VGA monitors on Lenovo IdeaCentre H520 Desktop

  - by Sebastian-Laurentiu Plesciuc

  I recently bought a Lenovo IdeaCentre H520 computer and two VGA LED monitors. This particular PC has a dedicated NVIDIA Geforce GT630 video card and an integrated Intel HD Graphics 2500 video card. Both cards have VGA out. The Geforce card also has a HDMI out. I have installed Windows 8 and I can't seem to use both cards. I have connected both monitors, one to the VGA out of the Geforce card and one to the VGA out of the integrated card. I looked through the BIOS options for Video and I can only select the dedicated one, the integrate one or the Auto option. This kinda sucks. I was wondering what kind of options I have available. I have a VGA female to DVI A male adaptor, I was wondering if it could work if I can hook it to a DVI A female to HDMI male adaptor and plug one monitor into the VGA out of the Geforce video card and the other through both adapters to the HDMI out. Any chance this could work? I was looking online for a VGA to HDMI live cable but it's kind of expensive.

• Windows 7 - Remote Desktop - multiple credentials

  - by w-

  Hi, My home network consists of a couple XP machines and a windows 7 box. One of the XP boxes is like a shared server accessed via Remote Desktop. I have an account on there and my gf has another. Previously I was able to save RDC shortcuts to this shared server including credentials. So in order to access the server from a computer on the network, i just needed to open the shortcut. I thus would have two shortcuts, one for my account and one for my gf's. In windows 7, it seems to store credentials for a box based on machine name. i.e. i can only store one set of credentials per machine name. This seems incredibly stupid so my question is: In windows 7, is there some way to have RDC shortcuts that use different credentials to login to the same target box? thanks

• Software RAID for several HDs which retains files on each HD

  - by Fuxi

  Is there some kind of software/driver that would enable me to create one big volume out of several hard disks but retain the file structure on each HD? This would be in case where one hard disk crashes and only data on that HD will be lost. Windows 7 enables me to do that but in case one HD breaks all data will be lost.

• Using 4 monitors with 2 generic video cards... possible?

  - by Ikram

  I'm thinking of setting up 4 monitors in a grid, using two video cards, one card to feed each pair of monitors through the card's two DVI ports. The most important requirement for me is to have the grid of monitors act as one single huge screen. Is this scenario possible by using two generic cards like Radeon 4870s on a Windows 7 computer? (I've heard of Eyefinity, but 4870s don't have it) Another issue is that I only have one PCI-Express slot on my computer's motherboard, therefore I'll need to use one of the lesser PCI cards as the second video card. Will this pose problems?

• There is a commercial tool like Xen + Remus?

  - by SoMoS

  Hello, I have a project where we need a completely redundant system like the one offered by Remus with a Xen virtualization system. I wondered if there is a system like this one built by VMWare or some other company because the project is a very critical one and we do not want to have to wait that a bug is fixed by "the community" and money is not a problem. What Remus does is to build a completely redundant system where you can shutdown one machine and the other continues the work where the other left it maintaining the network connections opened, etc Any hint? Thanks in advance.

• Dead drive in LVM/XFS configuration

  - by Freddie Witherden

  I had three drives in LVM: a 2 TB drive and two 1 TB drives (added later). One of the 1 TB drives -- I believe the third one -- has died. Spanning all three drives was an XFS partition. Reading: http://www.novell.com/coolsolutions/appnote/19386.html I see that one way of handling this is to replace the dead drive and copy the metadata over. However, I am currently not in possession of a 1 TB drive and can not readily acquire one. Given this, what are my options? There was nothing important on the drives (if there was I would have them in RAID 1) but I would not mind attempting a recovery. Is there a simple way of forcing LVM to go with just two drives and NUL out anything else? (So that fsck can do its thing.)

• enable vnc on xen without having to shut down all the domains

  - by bobinabottle

  The last guy forgot to enable vnc connections on our Xen blade and I need to install a windows domain, is there any way I can enable vnc without shutting down half our company? From what I can tell I need to edit xend-config.sxp which would likely require a restart of xend, which means shutting down all the running domains. Is there any way around this? thanks :)

• PHP on several servers with session-sharing

  - by Etu

  there's certanly other threads about this, but I have one more question. We are about to scale the website at work to have more than one server. And we need to share the sessions between the servers. We have been looking into different solutions, one in memcached and use Memcached as sessionhandler in PHP. That will probably work. And the idea would be to run memcached on every machine and let all webservers access all other servers memcached servers, and then we have shared sessions between the machines, yay. (we have no resources to setup with sticky-sessions yet, that's a later project. we need this running, and we need this running now. and we will loadbalance with DNS for a starter) But then... If I want to take one server down, say, for maintenance, or a server crashes, or whatever reason. I don't want the users to just loose their sessions and have to start from the beginning... That's why we need some kind of replication, which Memcached does not support. Then I found http://repcached.lab.klab.org/ -- which has multi-master replication of memcached, which is great, and is what I want. But does it work with 2 machines? Say 3, 5, 10? For future scaling. I also looked into redishttp://redis.io/ -- which also seems great, but is a bit more "shaky" with the php-session-handler support, and no multi-master-replication. The thing is that I like to use memcached, but I want to be able to power down one of two boxes without loosing half of the sessions. Any suggestions?

• Custom PCI bracket with support, for custom PCB?

  - by newbiez

  I am considering to put a custom PCB card that I made, into my computer. It won't go on any PCI connector, it plugs in on a USB connector on the motherboard, via a ribbon cable. I need thou to plug a device to it; which means that either I leave the PCB outside the case, hanging by the ribbon (bad idea), or I could put it in a PCI slot, using a bracket. The issue is that the brackets that I have, do not have tabs, so I have no way to screw the PCB on them. I was hoping to find something that would allow me to put the PCB on it, and then just fit it in the PCI bracket opening, like this: http://www.idotpc.com/TheStore/pc/viewPrd.asp?idproduct=1203&idcategory=0 This one won't fit the bill since the holes are too close apart, compared to the one that I have already on the PCB (and can't make more holes). Do you know if there is a place where they make universal PCI bracket mounting systems for custom PCB? I just need one, so can't even order a custom one (they ask me 120 dollars for one). Thanks in advance!

• Excel shows different files in same window

  - by pacoverflow

  In a browser, I downloaded an Excel spreadsheet and it displayed a dialog box asking what to do with it, so I selected "Open in Excel". Then I downloaded another Excel spreadsheet and opened that one in Excel as well. My taskbar shows 2 Excel icons, but there's only one Excel window. When I use the taskbar to switch between the spreadsheets, each one replaces the other in the Excel window. How can I get 2 Excel windows - one for each spreadsheet? I am running Windows 7 with Excel 2010.

• I need to preserve a tape using symantec backup exec. I'm aving trouble doing so

  - by MrVimes

  Please forgive me if this is the wrong stack exchange site. Please suggest which one I should post this to if it is. There's an automatic tape machine running in a remote location, with software (symantec backup exec 11d) Recently one of the servers being backed up had problems with its raid controller, so one of the drives has become invisible. I need to preserve the last good backup of that drive so I am trying to replace the tape with the most recent backup of that drive on it with one of the scratch tapes (blank tapes) present in the machine. I've tried the following... Associate the blank media with the media set in question (Wednesday) For the existing media (the tape with the data I want to keep) I click 'move to vault' and move it to the offline vault. I associate it with something other than 'Wednesday' (a media set called 'keep data infinitely...') I then do an inventory on that slot. The above steps I'm led to believe are supposed to put the fresh tape in the slot that had the tape I want to keep in it. But it just keeps showing up as containing the tape I want to keep after the inventory. (after refreshing the device tree) I am a complete newbie with this software. Can you tell me what I'm doing wrong, and/or tell me how to acheive my desired goal Edit: Just want to point out that I did try to get help directly from symantec with this, but having jumped through countless hoops to create an account and create a support ticket my progress was halted by requiring something called a 'tecnical contact id' at the final step with no explanation of what it is or how to get one.

• Which firewall ports do I need to open in order for a domain trust to work?

  - by Massimo

  I have two Active Directory domains in two different forests; each domain has two DCs (all of them Windows Server 2008 R2). The domains are also in different networks, with a firewall connecting them. I need to create a two-way forest trust between the two domains and forest. How do I configure the firewall to allow this? I found this article, but it doesn't explain very clearly which traffic is required between DCs, and which traffic (if any) in needed instead between domain computers in one domain and DCs for the other one. I'm allowed to permit all traffic between the DCs, but allowing computers in one network to access DCs in the other one would be a little more difficult.
