• Migrating an Active Directory domain controller to AWS

  - by Xavier Hutchinson

  I am required to migrate a Active Directory server into AWS with a couple other servers (SQL and IIS) to create a dev and test environment for our network / development. My plan at this time is to simply rebuild the Active Directory server in AWS from scratch - which is quite time consuming indeed! I was wondering if anyone had a recommendation as to a better and more efficient approach of migrating a copy of a physical Active Directory server to the cloud? The server is Windows Server 2012. Thank you!

• Can one build a single disk RAID 1 array?

  - by Core Xii

  I have an Nvidia hardware RAID 1 array and need to reformat. But I don't have any spare storage media, so I need to get along with the 2 disks in the array. I figured I'd do as follows: Delete the array, so I have 2 separate but identical disks, A and B, with my files Put disk B aside Reformat disk A, build RAID 1 array with it, install Windows XP Put disk B back in Boot to Windows on disk A, copy my files from disk B to disk A Add disk B to the RAID 1 array, rebuild array And now I'd have a new RAID 1 array, fresh install and all my files intact (the ones I copied). Here are the parts I'm unsure about: Can I build a RAID 1 array using just one disk, then add the other one later? Can Windows on disk A see disk B and allow me to copy my files over?

• Is it possible create a 4TB bootable partition in the x86 edition of Windows Server 2003 Enterprise?

  - by Giffyguy

  I'd like to find out if there is any way to accomplish this, since it would benifit my storage server greatly. I am using a Promise FastTrak 8660 and five Seagate ST31000340NS 1TB drives in a RAID 5 array. I figure that if the x86 ENTERPRISE edition of Server 2003 can handle 64GB of RAM, it should have no problem supporting larger HDD volumes as well. I've read (somewhere...) that the Windows Server operating systems are not limited to the standard 2TB like Windows XP and 2000 are. I'm hoping it's something that just needs to be turned on, similar to the way PAE works for the 4GB RAM limit in x86 servers.

• Options for PCI-DSS on AWS - file integrity monitoring and intrusion detection

  - by Brill Pappin

  I need to deploy some file integrity monitoring and intrusion detections software on AWS instances. I really wanted to use OSSEC, however it does not work well in an environment where servers can auto deploy and shut down based on load, because it requires server managed keys to be generated. Including the agent in the AMI will not allow monitoring as soon as it comes up because of that. There are many options out there, and several are listed in other posts on this site, however none that I've seen so far deal with the unique problems inherent in AWS or cloud based deployments in general. Can anyone point me at some products, preferably open source, that we might use to cover those portions of PCI DSS that require this software? Has anyone else achieved this on AWS?

• Xen private networking between multiple hosts

  - by Joe

  I have two physical hosts running Xen 3.2, sharing storage via iSCSI. On these two hosts are a number of domUs and I'd like to network them in multiple private networks so they can only contact other domUs on their private network. My understanding of the xen documentation suggests it's possible to do this within one dom0 (ie create virtual networks between domUs), but I've found nothing explaining how this can be implemented across multiple dom0s on different hosts. The only thing that jumps to mind is manually creating iptable rules to route data to the other host, but this seems to lack elegance and could quickly grow cumbersome. Any suggestions? All advice is much appreciated!

• FreeNAS - how to "Exclude from file" in Rsyncd (GUI)

  - by user179181

  I am trying to set rsync tasks to Pull user profiles from 11 Windows machines running DeltaCopy Server and then configure ZFS periodic snapshot tasks for a backup solution. So far this has been working fine, although i would like to exclude certain file types like .DAT or NTUSER.DAT. My Exclusion file resides on the local ZFS Dataset (Receiving side) and is as follows: Temp Temporary Internet Files NTUSER.DAT NTUSER.DAT.LOG *.dat *.tmp *.DAT.log *.ost *.pst The command i typed under Auxiliary Parameters (Rsyncd Global Conf under services)is as follows: exclude from = /mnt/Storage/User_Profiles/exclude.txt Ive tried deleting the .DAT files from the receiving end and just as i start to get excited i click refresh and there they are again

• Best "Keep your music with you" setup

  - by solomongaby

  I really enjoy listening to music, and because of this i have a lot of sources for it. This is not always a good thing since i have my music stored on a lot of devices ( home computer, work computer, online storage, ipod ) and sometimes its a bit difficult to have the same music in all places. Sometimes i dont have the same songs in all the places, i make a playlist in one place and want it in the other place etc. How do you keep your music in sync on all your devices. PS: i use both windows and linux.

• Create and use intermediate certificate authority on Windows Server 2012?

  - by Sid

  Background: Server OS is Windows Server 2012. GUI is installed as we come upto speed with powershell. Setup is staging, not production (yet). We have our (internal, domain limited) Root CA installed. I would like to take the Root CA offline to secure storage but before that I'd like to setup an intermediate CA which can take over actual live, online (int-RA-net) functionality Can someone guide me covering: creating the intermediate CA certificate request installing the intermediate CA certificate on domain controller (certification authority role already installed with Root CA online right now) use the intermediate CA to generate a certificate (any use certificate, just for demonstration purposes) Obviously this certification chain would be invalid on computers outside our domain (self trusted root - our root certificate is NOT from common 3rd parties). This last point is NOT a problem.

• Backup Client/Server Software that Syncs only the Delta?

  - by Urda

  I have a co-located server, and a desktop computer. I push small things and large ammounts of small files (like my iTunes) into a JungleDisk cloud. If a few files change there, no big deal, the file gets re-uped. For larger files JungleDisk backup isn't helpful. Things like movies and VMware images that change a lot, but I want backed up. Just not to JungleDisk since that would cost me even more money. I am looking for a product, closed or open source (preferably open source) that will sync the change, or delta, to my personal server on a schedule. That way I can keep a copy of my larger things, without paying JungleDisk a ton more since they are in the range of many Gigabytes. Right now these few items are backed up over FTP, and take forever. Both the client and server are windows environments.

• Ubuntu 12.04 VPS doesn't boot with mysql in nsswitch.conf

  - by chrisv

  1and1 VPS ("dynamic cloud server") does not boot any more as soon as mysql lookup is enabled in nsswitch.conf - any suggestions appreciated. Minimal setup to reproduce the problem: install Ubuntu 12.04 / LTS minimal server image install mysql-server, libnss-mysql-bg, nscd configure /etc/libnss-mysql.cfg and /etc/libnss-mysql-root.cfg set up appropriate database tables configure nss lookups through mysql in nsswitch.conf passwd: compat mysql group: compat mysql shadow: compat mysql Now, when I try to reboot the server it just hangs. No logs (maybe due to /var not yet being mounted), and I can't see console output (since this is a VPS). Booting into recovery image and removing "mysql" from /etc/nsswitch.conf makes the system bootable again, so this is definitely related to nsswitch/libnss-mysql-bg. There's a thread on gentoo-users which seems to describe a similar problem, unfortunately there's no real solution described, also the thread is rather old (from 2006) so I'm not sure whether this applies to me at all.

• Best way to replicate servers

  - by Matthew

  I currently have two servers both with linux software RAID1 configurations. They use heartbeat and DRBD to create a shared DRBD device that hosts a a exported NFS directory. The servers run Ubuntu Server with a LXDE GUI and some IP These servers are going to be placed on fishing vessels to act has redundant storage for IP cameras. My boss wants me to figure out the most efficient way to create these servers. We might be looking at pushing out several systems a week. Each configuration will be almost identical besides IP addressing. What would be the best method to automate the configuration process? We are trying to cut down on labor costs to set these up. Imaging and Proceeding are both on my mind right now

• Network adapters reliability

  - by casey_miller

  Can you help me with understanding of reliability of network adapters. Most of the time servers do have at least 2 NIC's bonded to provide sort of a HA for it. So in case of one NIC fails, the second would still do the job. I wonder which factors work when you use network adapters. I know that, the most important and weakest part of any computer system is: storage (i.e HDD). but how reliable actually network adapters are? There are more expensive ones, and cheaper adapters. In which cases do they actually fail? In what circumstances. May it be a intensive usage of them Time when it's on In your experience how often you found yourself changing NIC's due to their fail? Or just what's the typical lifetime of commodity NIC's? thanks.

• Laptop stopped recognizing USB hard drive

  - by vahokif

  Hi, My Packard Bell EasyNote TX86 laptop stopped recognizing my 1 TB Toshiba Store Art hard drive. It worked fine until now, and it still works on other computers. Other USB devices (including storage) work, and I've tried plugging it in every port, to no avail. When I plug it in it spins up, but Windows doesn't react at all (it's not in disk management), Linux doesn't write anything in dmesg and I can't see it in BIOS setup. I didn't use it at all today, apart from plugging it into a freshly-installed Windows 7 machine once (where it worked). What can I do? Which device is to blame here? EDIT: One more thing. I unplugged the drive while the laptop was hibernated. Google says this might be the problem and it might have something to do with resetting the USB Host Controller.

• Determine Server specs for a Rails with MySQL database (on AWS)

  - by Rogier

  I developed a intranet applications with Rails (3.2) for one of my customers. There will be around 30-40 employees working with it. Backend is MySQL (5). What would be the best way to determine the servers specs needed? Given: max. load will be roughly 2400 (40*60) HTTP requests (mixed GET / POST) per hour. 15% of these calls are JSON calls (iOS) avg request will make between 5-10 database calls 500-800 SQL INSERTS per day webpages are fairly simple (no images, just text) avg webpage is 15 request (css/js/etc) and total size is 35-45 KB More specific, since they need access from multiple geographical locations, we are thinking of running a bitnami Ruby stack in the AWS cloud (uptime is important). Any thoughts on a AWS Instance (small/medium) and Utilization (light/medium/heavy) ? Thanks!

• SQL 2008 R2: Data\Log partions

  - by Reese Hirth

  I have a SQL Server setup that a previous IT person set up with a 2TB data partition and a 1TB log partition. The OS partition is 244GB and SQL is installed on a separate 1TB partition. We have an additional 8TB of storage that I would like the new IT staff to bring on line. He wants to create 4 new 2TB data partition. I see this as confusing. Can't we just backup the current data partition, blow it away, and create a new 10TB data partition I'm responsible for administering the data on the server but am not allowed to do the setup myself. This is a GIS server running ArcGIS Server with around 60 geodatabases ranging from 20BG to a couple that may grow to over a TB. So, 5-2TB data partitions or 1-10TB partition. Thanks for the advice.

• Suggestions for a SOHO/Home Asterisk system

  - by James

  I would like to buy a small embedded system that runs Linux and Asterisk. I would like two FXS ports ( to plug analogue phones into ) and one FXO port ( to plug in to my real line to allow access to the POTS ). I would like it to have a USB port to hold storage for voicemail. I really want it for home use so I would like it to be under £150 ( say $250 ), given that you can buy ADSL routers for around this much can any of them be made to run Linux and Asterisk? I don't want a PC as the power usage would be too high. I am looking for something like this ASDL router but open and able to run Asterisk or another open PBX. At worst I would like a box which had one FXO and two FXS and just made them completely available over IP to a full Asterisk system on a low power Atom system.

• Parity Initialization after putting in two new disks

  - by lbanz

  All my firmware is up to date on the server and the controllers. Storage crashed over the weekend. I rebooted it and it detected that I put in two new disks last week (I did check that both disk completed the rebuilding process last week). After it booted into the OS I see that it gave me an information message. After 18 hours it is at 54% so it is looking healthy. But I need to replace 5 more disk in the msa. Should I wait for this message to finish before replacing more disks? 785 Background parity initialization is currently queued or in progress on Logical Drive 1 (15.0 TB, RAID 5). If background parity initialization is queued, it will start when I/O is performed on the drive. When background parity initialization completes, the performance of the logical drive will improve.

• Blender Render Cycles

  - by usersuper

  I get a very poor Render in cycles. Not just minor problems, but just a cloud of of black and white dots and no contour at all. I read a lot about this now and couldn't get it to work. Does anybody know how to get the settings right. Or better what do I have to pay attention to get better renders. I also tried external renderer like Lux, which increased my CPU usage to 98 % (just the default cube and clicking on Lux and load materials). Is this normal and what could i do to improve that. I have various versions of Blender (2.61,2.62,2.63) on Mac OS X. Thanks for the time.

• PowerShell create new Azure VM from uploaded disk (not image)

  - by MikeBaz

  I have a VHD in Azure storage. That VHD is configured as an OS disk through a command like the following: Add-AzureDisk -DiskName $newCode -MediaLocation "http://$script:accountName.blob.core.windows.net/$newCode/$sourceVhdName.vhd" ` -Label $newCode -OS "Windows" I would like to create a new VM pointing at that disk. From what I can tell if I was doing this with an image I would do something like: New-AzureVMConfig -Name $newCode -InstanceSize $instanceSize ` -MediaLocation "http://$script:accountName.blob.core.windows.net/$newCode/$sourceVhdName.vhd" -ImageName $newCode ` | Add-AzureProvisioningConfig -Windows -Password $adminPassword ` | New-AzureVM -ServiceName $newCode However this is wrong for me because I don't have an image - I have a configured VHD that is not sysprepped and can't be. How can I create the VM in PowerShell to point at the existing disk like I can through the portal?

• How do I start DB2 on an Amazon EC2 Volume?

  - by Spike Williams

  I've got an instance of DB2 installed as part of an IBM WebSphere Portal development AMI on the Amazon EC2 cloud. Its installed a separate, persistent file system from the rest of the AMI. Yesterday, the AMI was terminated, and DB2 went down as part of that. It was not shut down cleanly, just terminated. Today, I am trying to restart the WebSphere portal server, which needs to connect to the DB2 instance. But the DB2 instance is down. So I need to restart my DB2 instance, but how to do that is not immediately obvious. Can someone tell me what I need to run to get it going again? OS is SuSE Linux, DB2 version is 9.1

• System has reached the maximum size allowed for the system part of the registry

  - by Bob Denny

  To be precise System has reached the maximum size allowed for the system part of the registry. Additional storage requests will be ignored. WinXP/64 running fine for 2 years (no /3Gb switch), just started happening. I used ntregopt and the problem went away at least temporarily. However, looking before and after in Windows\System32\Config I see that my System file was reduced only by 10% and is still 170+ Mb. According to my rather extensive research with Google, this is "huge" and should be more like 10-20Mb. The system runs fine. There is a System.bak that is only 11Mb and has the date when I ran ntregopt. That's what I know. Now my question: Is there anything I can do to reduce or rebuild the System registry hive given the above info?
