• vSphere Client vCenter Template Customization Specification Using Windows Sysprep Unattended Answer XML File

  - by Brian

  I'm trying to setup a vSphere Client vCenter v5.0.0 Build 455964 Template Customization Specification using a Windows Sysprep unattended answer XML file for Win2008R2. However I didn't know how Sysprep worked before attempting this so it was a time-consuming nightmare (even after reviewing VMware vSphere ESXi 5's documentation)! I think I've figure out what I'm supposed to be doing, but it's still not working. The biggest problem at this point is that vSphere Client vCenter Customization Specification IP address information is not sticking when I load a Sysprep XML file with just 1 basic setting! This can only be a bug. Here is the process I'm using: PROCESS for Windows - vSphere Client Install Windows OS install VM Tools customize Windows (GPOs can be used to do this after deployment) install Applications (GPOs can be used to do this after deployment too) shutdown the VM convert the VM to a template create a custom Windows Sysprep XML answer file with desired customizations View Management Customization Specifications Manager create "New" Specification for "Target Virtual Machine OS" select Windows check "Use Custom Sysprep Answer File" (ADDS: Custom Sysprep File. KEEPS: Network (IP), Operating System Options (SID, Sysprep /generalize). REPLACES: Registration Information of Owner Name & Organization, Computer Name, Windows License (Key), Administrator Password, Time Zone, Run Once, Workgroup or Domain) name it as "VMwareCS-OS####R#x32/64w/Sysprep-TEST" (CS=Customization Specification) set Description as "Created YYYY/MM/DD by FLast" NEXT import a Sysprep answer file from secure location NEXT Custom settings NEXT click "..." box to right of "Use DHCP" set "Use the following IP settings:" for "IP Address" fill out the first 2 octets set appropriate values for other 2-3 fields set DNS server addresses OK NEXT check "Generate New Security ID (SID)" ALWAYS as template is likely a domain-member computer so it can be updated occasionally NEXT Finish View Inventory VMs and Templates right-click previously completed template Deploy Virtual Machine from this Template provide the new OS name (max15char) select inventory location NEXT select Host/Cluster (wait for validation to succeed) NEXT select Resource Pool (wait for validation to succeed) NEXT select Storage location NEXT check "Power on this virtual machine after creation" select "Customize using an existing customization specification" select desired specification select "Use the Customization Wizard to temporarily adjust the specification before deployment" NEXT NEXT Custom settings? NEXT check "Generate New Security ID (SID)" ALWAYS as template is likely a domain-member computer so it can be updated occasionally NEXT Finish Finish. I know a community member named "brian" (http://serverfault.com/users/25904/brian) has worked with this scenario before, but I couldn't figure out how to contact him directly, so Brian if you see this message could you provide some information to help? Thanks, Brian

• What is the difference between Anycast and GeoDNS / GeoIP wrt HA?

  - by Riyad

  Based on the Wikipedia description of Anycast, it includes both the distribution of a domain-name-to-many-IP-mapping across many DNS servers as well as replying to clients with the most geographically close (or fastest) server. In the context of a globally distributed, highly available site like google.com (or any CDN service with many global edge locations) this sounds like the two key features one would need. DNS services like Amazon's Route53, EasyDNS and DNSMadeEasy all advertise themselves as Anycast-enabled networks. Therefore my assumption is that each of these DNS services transparently offer me those two killer features: multi-IP-to-domain mapping AND routing clients to the closest node. However, each of these services seem to separate out these two functionalities, referring to the 2nd one (routing clients to closest node) as "GeoDNS", "GeoIP" or "Global Traffic Director" and charge extra for the service. If a core tenant of an Anycast-capable system is to already do this, why is this functionality being earmarked as this extra feature? What is this "GeoDNS" feature doing that a standard Anycast DNS service won't do (according to the definition of Anycast from Wikipedia -- I understand what is being advertised, just not why it isn't implied already). I get extra-confused when a DNS service like Route53 that doesn't support this nebulous "GeoDNS" feature lists functionality like: Fast – Using a global anycast network of DNS servers around the world, Route 53 is designed to automatically route your users to the optimal location depending on network conditions. As a result, the service offers low query latency for your end users, as well as low update latency for your DNS record management needs. ... which sounds exactly like what GeoDNS is intended to do, but geographically directing clients is something they explicitly don't support it yet. Ultimately I am looking for the two following features from a DNS provider: Map multiple IP addresses to a single domain name (like google.com, amazon.com, etc. does) Utilize a DNS service that will respond to client requests for that domain with the IP address of the nearest server to the requestee. As mentioned, it seems like this is all part of an "Anycast" DNS service (all of which these services are), but the features and marketing I see from them suggest otherwise, making me think I need to learn a bit more about how DNS works before making a deployment choice. Thanks in advance for any clarifications.

• Backup VM : Copy virtual disk xxx.vmdk The virtual disk is either corrupted or not a supported forma

• DPM 2010 PowerShell Script to Easily Restore Multiple Files

  - by bmccleary

  I’ve got what I thought would be a simple task with Data Protection Manager 2010 that is turning out to be quite frustrating. I have a file server on one server and it is the only server in a protection group. This file server is the repository for a document management application which stores the files according to the data within a SQL database. Sometimes users inadvertently delete files from within our application and we need to restore them. We have all the information needed to restore the files to include the file name, the folder that the file was stored in and the exact date that the file was deleted. It is easy for me to restore the file from within the DPM console since we have a recovery point created every day, I simply go to the day before the delete, browse to the proper folder and restore the file. The problem is that using the DPM console, the cumbersome wizard requires about 20 mouse clicks to restore a single file and it takes 2-4 minutes to get through all the windows. This becomes very irritating when a client needs 100’s of files restored… it takes all day of redundant mouse clicks to restore the files. Therefore, I want to use a PowerShell script (and I’m a novice at PowerShell) to automate this process. I want to be able to create a script that I pass in a file name, a folder, a recovery point date (and a protection group/server name if needed) and simply have the file restored back to its original location with some sort of success/failure notification. I thought it was a simple basic task of a backup solution, but I am having a heck of a time finding the right code. I have seen the sample code at http://social.technet.microsoft.com/wiki/contents/articles/how-to-use-a-windows-powershell-script-to-recover-an-item-in-data-protection-manager.aspx that I have tried to follow, but it doesn’t accomplish what I really want to do (it’s too simplistic) and there are errors in the sample code. Therefore, I would like to get some help writing a script to restore these files. An example of the known values to restore the data are: DPM Server: BACKUP01 Protection Group: Document Repository Data Protected Server: FILER01 File Path: R:\DocumentRepository\ToBackup\ClientName\Repository\2010\07\24\filename.pdf Date Deleted: 8/2/2010 (last recovery point = 8/1/2010) Bonus Points: If you can help me not only create this script, but also show me how to automate by providing a text file with the above information that the PowerShell script loops through, or even better, is able to query our SQL server for the needed data, then I would be more than willing to pay for this development.

• Real server, Multiple IP Addresses, HyperV Virtual Server, How to partition IPs across real and Virtual NICs

  - by Steven_W

  This is a slightly difficult problem to explain without same basic background information - I'll try and refine the question later as necessary Originally, I have a single hosted server (Win 2008R2) with the following range of 8 IP addresses. - Single NIC - IP: x.x.128.72 -> x.x.128.79 - Subnet: x.x.255.192 - GW: x.x.128.65 After installing Hyper-V and setting up a single virtual server on the same box, I then wanted to assign one of the IP addresses to the virtual server, leaving everything else running normally. -- Firstly, I tried using the "External" network, but (even after setting IPs on the "Virtual Adapter" similar to Here but struggled to get networking running at all. I needed to keep the server running (otherwise I would have spent more time pursuing this approach) Q1 ... Was this a sensible thing to do ? Should I have carried on down this route ? -- I then decided to try different approach - Set the HyperV network to "Internal" (visible to Management OS) - Physical NIC - IP: x.x.128.72 -> x.x.128.75 - Subnet: x.x.255.192 - GW: x.x.128.65 - Virtual NIC - IP: x.x.128.78 - Subnet: x.x.255.252 - GW: x.x.128.72 ... { The same as the IP of the physical NIC ) - Virtual OS-NIC - IP: x.x.128.77 - Subnet: x.x.255.252 - GW: x.x.128.78 ... { The same as the IP of the host virtual-NIC ) -- Surprisingly enough, this approach actually worked, and I was able to connect from all the following: - Internet to/from physical NIC (x.x.128.72) - physical NIC (x.x.128.72) to virtual-OS-NIC (x.x.128.77) e.g. testing via ping + FTP - Internet to/from virtual-OS-NIC (x.x.128.72) -- The problem I have is that this approach seems to only last for a short while (a few hours). After this time, it seems that I lose the ability to connect from Virtual-OS-NIC to/from the internet (but I can still connect from the host-OS to the virtual-OS and from the host-OS to the internet) I have re-tested this a couple of times with the same results ... I leave the server on for a few hours (e.g. overnight), and when I come back in the morning, the Virtual-OS loses the ability to route to the internet -- I'm not quite sure what to look at next (or whether I'm going about this completely the wrong way ) One "possible relevant item" is that the host-OS is also running RRAS (Routing and Remote Access), but this is only to run a simple VPN -- Q2 - Wheat should I be looking at next ? (Any good references / recommendations of what to try) Would appreciate any thoughts or comments (even if you tell me I'm going about this the wrong way)

• multiple webapps in tomcat -- what is the optimal architecture?

  - by rvdb

  I am maintaining a growing base of mainly Cocoon-2.1-based web applications [http://cocoon.apache.org/2.1/], deployed in a Tomcat servlet container [http://tomcat.apache.org/], and proxied with an Apache http server [http://httpd.apache.org/docs/2.2/]. I am conceptually struggling with the best way to deploy multiple web applications in Tomcat. Since I'm not a Java programmer and we don't have any sysadmin staff I have to figure out myself what is the most sensible way to do this. My setup has evolved through 2 scenarios and I'm considering a third for maximal separation of the distinct webapps. [1] 1 Tomcat instance, 1 Cocoon instance, multiple webapps -tomcat |_ webapps |_ webapp1 |_ webapp2 |_ webapp[n] |_ WEB-INF (with Cocoon libs) This was my first approach: just drop all web applications inside a single Cocoon webapps folder inside a single Tomcat container. This seemed to run fine, I did not encounter any memory issues. However, this poses a maintainability drawback, as some Cocoon components are subject to updates, which often affect the webapp coding. Hence, updating Cocoon becomes unwieldy: since all webapps share the same pool of Cocoon components, updating one of them would require the code in all web applications to be updated simultaneously. In order to isolate the web applications, I moved to the second scenario. [2] 1 Tomcat instance, each webapp in its dedicated Cocoon environment -tomcat |_ webapps |_ webapp1 | |_ WEB-INF (with Cocoon libs) |_ webapp1 | |_ WEB-INF (with Cocoon libs) |_ webapp[n] |_ WEB-INF (with Cocoon libs) This approach separates all webapps into their own Cocoon environment, run inside a single Tomcat container. In theory, this works fine: all webapps can be updated independently. However, this soon results in PermGenSpace errors. It seemed that I could manage the problem by increasing memory allocation for Tomcat, but I realise this isn't a structural solution, and that overloading a single Tomcat in this way is prone to future memory errors. This set me thinking about the third scenario. [3] multiple Tomcat instances, each with a single webapp in its dedicated Cocoon environment -tomcat |_ webapps |_ webapp1 |_ WEB-INF (with Cocoon libs) -tomcat |_ webapps |_ webapp2 |_ WEB-INF (with Cocoon libs) -tomcat |_ webapps |_ webapp[n] |_ WEB-INF (with Cocoon libs) I haven't tried this approach, but am thinking of the $CATALINA_BASE variable. A single Tomcat distribution can be multiply instanciated with different $CATALINA_BASE environments, each pointing to a Cocoon instance with its own webapp. I wonder whether such an approach could avoid the structural memory-related problems of approach [2], or will the same issues apply? On the other hand, this approach would complicate management of the Apache http frontend, as it will require the AJP connectors of the different Tomcat instances to be listening at different ports. Hence, Apache's worker configuration has to be updated and reloaded whenever a new webapp (in its own Tomcat instance) is added. And there seems no way to reload worker.properties without restarting the entire Apache http server. Is there perhaps another / more dynamic way of 'modularizing' multiple Tomcat-served webapps, or can one of these scenarios be refined? Any thoughts, suggestions, advice much appreciated. Ron

• Automatically Applying Security Updates for AWS Elastic Beanstalk

  - by Eric Anderson

  I've been a fan of Heroku since it's earliest days. But I like the fact that AWS Elastic Beanstalk gives you more control over the characteristics of the instances. One thing I love about Heroku is the fact that I can deploy an app and not worry about managing it. I am assuming Heroku is ensuring all OS security updates are timely applied. I just need to make sure my app is secure. My initial research on Beanstalk shows that although it builds and configures the instances for you, after that it moves to a more manual management process. Security updates won't automatically be applied to the instances. It seems there are two areas of concerns: New AMI releases - As new AMI releases hit it seems we would want to run the latest (presumably most secure). But my research seems to indicate you need to manually launch a new setup to see the latest AMI version and then create a new environment to use that new version. Is there a better automated way of rotating your instances into new AMI releases? In between releases there will be security updates released for packages. Seems we want to upgrade those as well. My research seems to indicate people install commands to occasionally run a yum update. But since new instances are created/destroyed based on usage it seems that the new instances would not always have the updates (i.e. the time between the instance creation and the first yum update). So occasionally you will have instances that aren't patched. And you are also going to have instances constantly patching themselves until the new AMI release is applied. My other concern is that perhaps these security updates haven't gone through Amazon's own review (like the AMI releases do) and it might break my app to automatically update them. I know Dreamhost once had a 12 hour outage because they were applying debian updates completely automatically without any review. I want to make sure the same thing doesn't happen to me. So my question is does Amazon provide a way to offer fully managed PaaS like Heroku? Or is AWS Elastic Beanstalk really more of just a install script and after that you are on your own (other than the monitoring and deployment tools they provide)?

• Why is user asked to choose their workgroup?

  - by Clinton Blackmore

  We running Mac OS X Server 10.5.8 with Mac OS X 10.5.8 clients. Students use network logins to, well, log in. I've been asked to deny internet access to a specific user. I was told that a good way to do it is to create a user workgroup called "No Internet Access" and manage settings there. (Specifically, I told parental controls to allow access to no sites, and blacklisted all the installed web browsers). Now, when the user authenticates to log in, they are greeted with this dialog: Workgroups for <username> Grade 7 Students No Internet Access It is unlikely that the student would willing choose "No Internet Access" to be their base group. Looking in Workgroup Manager at the student's record, it shows their primary group ID is the grade 7 group, and "No Internet Access" is listed as another group they belong to. I looked at the managed preferences for all the computers pertaining to logins. They are set to their defaults. Specifically, the computer groups' preference for Logins - Access has the defaults: [unchecked] Ignore workgroup nesting [checked] Combine available workgroup settings Based on my reading of Tips and Tricks for Mac Administrators, this should be correct, the user should not be asked which group they belong to, and settings from all applicable groups should be applied. How can I achieve that result? Edit: I've decided to add some additional information from the Tips and Tricks for Mac Management White Paper (via Apple in Education, via the author's site). On page 21, it says: With Leopard MCX, workgroup preference settings are combined by default into a single set of values. This means that instead of having to choose between the Math, Science, or Language Arts workgroups when logging in, a user can just authenticate and be taken directly to the desktop. All the settings for each of those workgroups are composited together, providing you with all the Dock items and a composite of all the other settings. On page 40, an example is given in which settings are combined from different 'domains', one computer group, two (user) workgroups, and one individual user's settings. [When johnd logs into a leopard client,] the items staged in the Dock from left to right are: computer group, first workgroup alphabetically, second workgroup, user. Items within the workgroup are staged alphabetically. Nowhere is there an indication that groups are nested; indeed, I can see no sensible (non-flat) heirarchy for groups like Math, Science, and Language Arts. I strongly believe that there is a way to apply settings from two unrelated user workgroups such that a user of OS X 10.5.x or newer does not need to choose their workgroup. This is what I seek to achieve.

• DPM 2010 "Disk failed or disk not found"

  - by SysAdmin

  I have an HP Proliant ML110 G5 server with Windows server 2008R2 only dedicated for DPM 2010. This server has a limit in HD of 8TB which has already been met. I'm now stuck in this situation where my disk keeps failing "Disk failed or Disk not found" in the disk management. Only after I reboot the system the disk comes back up. Today I was running my monthly tape backup on a certain protection group and the disk failed again while the tape job was running (so the job wasn't completed). This is the description of the error in the alerts: "The disk Disk 1 - Hitachi HDS722020ALA330 SCSI Disk Device cannot be detected or has stopped responding. All subsequent protection activities that use this disk will fail until the disk is brought back online. (ID 3120)". My backup system is becoming useless! I don't think that is a hardware issue (please correct me if I'm wrong) since the HD works fine for a certain period of time which is becoming shorter and shorter. I basically have no more option to fix this problem. I tried to fix any error that was coming up in the event viewer with no luck (included one regarding the SQL2008 compatibility issue). The disk keeps failing! Now I'm only trying to recover/migrate the data from the disk that is having problem but my issue now is that I cannot add any drives to my server since I already got installed the maximum storage capacity 8TB. I thought about 2 simple options. Please tell me what you guys think about it; Unplug one of the 2 storage pool disks (disk0, that one without problem) from the machine and install a new one in order to migrate the data with the Migration tool for DPM. Remove the defective disk (disk1), put back the disk0 and run the synchronization/consistency check on all the groups to recreate replicas and recovery points. Run diskpart.exe and clean up the disk (loosing all data) and hoping that he will work after I sync all the protection groups. Both solutions are not elegant but I have no better options at the moment. Please I need some help. Thanks for your time Angelo

• Issues getting a Cisco WLC 5508 to find AIR-LAP1142N

  - by user95917

  hoping someone can help me with a problem here. I'm attempting to setup a test (loan from Cisco) wireless network. Here's what i've got/done: 5508 Controller - Service Port IP set to 10.74.5.2 /24. Management IP set to 10.74.6.2 /24 with a default gateway of 10.74.6.1. Virtual IP set to 1.1.1.1. Copper SFP in slot 7, CAT5 (known good) going from there to port 1/0/47 on the switch. Green lights on both ends. 2960-S Switch - Vlan1 - 10.74.6.1 /24. dhcp pool 10.74.6.0 /24, default router 10.74.6.1. excluded-address 10.74.6.1, 10.74.6.2. 1/0/4 on the switch is set to switchport mode access and no shut. 1/0/47 on the switch is setup to switchport mode trunk and no shut. 1/0/4 has a CAT5 (known good) cable going from there to the AP. When I do a sh cdp nei from the switch, i can see the AP and Controller listed. When i configure my PC's nic to 10.74.5.5, and plug a cable from my nic to the SP port on the controller i can get on the device via the gui. In there, the only errors/info that show up in the trap are: Link Up: Slot: 0 Port: 7 Controller time base status - Controller is out of sync with the central timebase. I've manually set the time but apparently that's not quite the problem (or at least not the entire problem). When i plug the AP in, i see on the switch console that it grants it power, it sees it connect...but the controller won't see it for some reason. From what i've read you shouldn't have to do anything to the AP as it's managed by the controller...but i'm not sure what setting I'm missing for it to work. The AP light on top is continually cycling green, red, yellow. When I first start it up, it blinks green for 20 or so seconds, then goes to solid green for another 20 seconds or so, then flashes blue, green, red for awhile...but always ends up goinn back to the standard, green, red, yellow. Does anyone see any obvious issues with my setup or have any suggestions as to why i might be having a problem? Thanks for your help!

• Setting Timeouts: SQL Server 2008/IIS 7.5

  - by Julie

  We have recently migrated from a Win 2003/SQL Server 2000 system to Win 2008 64 bit R2, SQL Server 2008 R2. Our websites are in classic asp, and this can't be changed to another scripting language at this time. On the old server, if I got stuck in some kind of endless loop, the page would throw an error. On the new server, I have a page that has some sort of looping problem, that even though the SQL SP is called only once (and runs fine run as a query on the server) it pegs SQL server and therefore locks all of our websites. I'll get my code figured out, no biggie. But I need to make sure the server times out when this happens. (The page I'm working on runs fine with certain instances of the query, and locks with others using a different query variable. I can't have something like that sneak up on me on a page I haven't touched for three years.) I can't figure out how an SP that runs once on the server, from an ASP page, is tying up SQL server this way. It's obviously some sort of a timeout issue, but I can't figure out where/which timeout values to change. I actually have to remote desktop to the server and kill the process in SQL server. I'm afraid I'm a generalist, and server management is not my thing, even though it's my responsibility, so I am almost certain to have questions about any answer that I receive. How can I track this down? What settings do I need to change? More info: It's not SQL Server On our test site, I created an ASP file that just did an endless loop (do while 1=1) and had the same problem - the other websites wouldn't load - without SQL server being involved. So I think the reason the process was hanging is that the page wasn't timing out as it should, and so the connection to SQL was never closed. Killing the process in SQL server would reset the page somehow. For my intentional endless loop, I had to refresh the app pool to get rid of it. This points more to either IIS or the ASP settings. The ASP timeouts are set to whatever the default were when the server was first loaded. I still can't figure out why one file is locking up all websites, though. Again, that didn't happen on the old server.

• How do I get the latest FastCGI and PHP versions to peacefully coexist on IIS 6?

  - by BHelman

  I have been going round and round trying to get any sort of PHP running on IIS 6. I somehow managed to successfully get version 5.1.4 running using the php5isapi.dll file. However, I want to upgrade a website to begin using a Content Management System. I have never dug into CMS before so I'm open to programs that are easy to use. I am currently looking into TomatoCMS and ImpressCMS - but that's beside the point. I have never done an installation with PHP before and I think I'm getting familiar with how it works. However the current situation is this. Microsoft's Web Platform Installer 2.0 installed FastCGI for me. I need to upgrade to PHP 5.3.1 for a CMS system. So I downloaded the Windows installer and let it go at it. After consulting several other blog articles, I believe I know how it is supposed to work but I am currently not having luck. THE SETUP *.php is a registered extension in IIS 6 for all websites (on Win 2k3). The application that it calls is C:\Windows\system32\inetsvr\fcgiext.dll, like it should. The fcgiext.ini config has the proper lines: [Types] php=PHP [PHP] ext=C:\program files\PHP\php-cgi.exe And the php.ini file also has the correct configs. All extensions are disabled and I changed the correct things for FastCGI. And everything is registered correctly with the PATH variable. Everything is exactly how it should be. BUT when I launch the "info.php" page () on another computer, I get the following error: FastCGI Error The FastCGI Handler was unable to process the request. Error Details: * Section [PHP] not found in config file. * Error Number: 1413 (0x80070585). * Error Description: Invalid index. HTTP Error 500 - Server Error. Internet Information Services (IIS) A quick Google search reveals that I have it all setup correctly as far as the INI's go and the mapping of the php extension. I am completely at a loss. Does anyone have any suggestions? Although the server is hosting three small websites, I don't really care what I have to do to it to get it to work.

• OpenVPN, Great on Windows, VERY slow on Mac...

  - by Phsion

  Hello, I'm not really an IT Pro, but this seemed like the best place to ask this question... I have setup VPN networks in the past, for fun, and everything was great, but now I've set one up for my boss, and while my computers all work great, his Mac machines are almost too slow to work with. Its pretty much vanilla configs all around, anyone have any ideas? Its a TUN routing setup over UDP. Back Story: My boss travels a lot, and wants to be able to access all his files from the road, and is also pretty paranoid about security (even though knows almost nothing about computers). SO i figured a VPN would be the answer. I went with OpenVPN, but there are some other issues. The only ISP we can get in our area besides Dial-UP is a crappy Satellite provider, that doesn't offer public IPs unless your willing to pay, so while the computers and VPN setup are pretty vanilla, the routing and structure is strange to get around this limitation. Specs: Its OpenVPN2, and there are six machines using it (only three actually use it, the rest are my test machines), one Windows 7 laptop, two XP Desktops, one OS X 10.5 Desktop, one 10.6 Desktop, and one 10.6 Laptop. One XP Desktop sits at my house and acts as the server (6Mbs/2Mbs FIOS connection). One XP desktop sits at the office and hosts a webpage that will wake up the Main Mac Desktop from sleep, and also ping all the machines on the VPN and show their status. The main office mac (10.6) stays in sleep mode until it gets the Wake-On-Lan packet from the Office XP, and then it auto connects to the VPN and opens itself up. The reason for all this is the Satellite private IP crap means i cant directly access the office machines outside of the LAN, so everyone connects to my house first, then they talk to each other from there. The Wake On Lan weirdness is because my boss doesn't want to leave the main Mac on all the time, and making a quick and dirty webpage was the easiest way to send a Magic Packet from inside the LAN without confusing my boss. The VPN uses Client Config files to make static IPs for the client. The only thing i found in google was some changes to the VPN MTU settings (down to 1400) but no real help. Oh, and i forgot...all the windows machines just have OpenVPN start as a service. The Mac laptop uses tunnelblick (an OpenVPN GUI) and the Mac Desktops use OpenVPN in normal command line mode.

• Splitting an internet connection between multiple separate subnetworks

  - by pythonian4000

  Problem I have an internet connection that I want to split between four separate networks. My requirements are: I need to be able to monitor the amount of bandwidth and data being used by each network, and notify or control as necessary. The four networks should only be able to connect to the internet, not each other. My parents need to be able to operate it, so it needs a simple, preferably Windows-based GUI. Progress so far Server I have a mini-ITX server with six Gigabit ethernet ports - one for the ethernet internet connection, one for each of the four networks, and one for remote access to the server for administration. Bandwidth control I spent a long time researching solutions here. The majority of the control systems/software I found could control bandwidth usage via QOS, but could not monitor or control the amount of data being used. Eventually I found the SoftPerfect Bandwidth Manager, which has everything I need in terms of monitoring and control - per-interface quota management, usage statistics, a web interface for checking usage, and email notifications when quotas are exceeded. It is also Windows-based and has a simple GUI. Internet sharing This is where I am having issues. I am currently using Windows XP Pro SP2 for the server (yes, I know this is far from ideal, but it's the only spare Windows OS I currently have). I can't use the built-in Internet Connection Sharing for several reasons: The upstream internet router has an IP of 192.168.0.1 which ICS clashes with, and I cannot change the router settings. ICS can only share an internet connection with a single interface, but I have four. I have tried bridging the four network cards, but then the Bandwidth Manager cannot see the four individual interfaces - it only sees the bridge. I have tried setting up Dual DHCP DNS server (and am having issues getting DHCP offers to be received by clients), but that would still require gateway software of some sort, which I have been unable to find. My current attempt is to use OpenVPN, with a server for the internet NIC and a separate client for each of the four networks. My thought is that I could bridge the OpenVPN TAP devices to each NIC, meaning that the Bandwidth Manager would control traffic from the bridge instead of the interface. I have not made much progress here though - I've never used OpenVPN before. Questions Is there a Windows software package that does everything I need? (Unlikely, I know) Is there a Windows software package that will share internet between multiple NICs without bridging? Are either of my about attempts feasible? Would it help to have a newer/server version of Windows? Is there a non-Windows alternative that is easy to use?

• Using Amazon S3 for multiple remote data site uploads, securely

  - by Aitch

  I've been playing about with Amazon S3 a little for the first time and like what I see for various reasons relating to my potential use case. We have multiple (online) remote server boxes harvesting sensor data that is regularly uploaded every hour or so (rsync'ed) to a VPS server. The number of remote server boxes is growing regularly and forecast to keep growing (hundreds). The servers are geographically dispersed. The servers are also automatically built, therefore generic with standard tools and not bespoke per location. The data is many hundreds of files per day. I want to avoid a situation where I need to provision more VPS storage, or additional servers every time we hit the VPS capacity limit, after every N server deployments, whatever N might be. The remote servers can never be considered fully secure due to us not knowing what might happen to them when we are not looking. Our current solution is a bit naive and simply restricts inbound rsync only over ssh to known mac address directories and a known public key. There are plenty of holes to pick in this, I know. Let's say I write or use a script like s3cmd/s3sync to potentially push up the files. Would I need to manage hundreds of access keys and have each server customized to include this (do-able, but key management becomes nightmarish?) Could I restrict inbound connections somehow (eg by mac address), or just allow write-only to any client that was running the script? ( i could deal with a flood of data if someone got into a system? ) having a bucket per remote machine does not seem feasible due to bucket limits? I don't think I want to use a single common key as if one machine is breached then potentially, a malicious hack could get access to the filestore key and start deleting for ll clients, correct? I hope my inexperience has not blinded me to some other solution that might be suggested! I've read lots of examples of people using S3 for backup, but can't really find anything about this sort of data collection, unless my google terminology is wrong... I've written more than I should here, perhaps it can be summarised thus: In a perfect world I just want to have one of our techs install a new remote server into a location and it automagically starts sending files home with little or no intervention, and minimises risk? Pipedream or feasible? TIA, Aitch

• Deleting windows.edb and unchecking Indexing service lead to hard drive file records swapping

  - by linni

  I followed the instructions listed here:http://www.mydigitallife.info/2007/09/18/turn-off-and-disable-search-indexing-service-in-windows-xp/ to free up space on hard drive by deleting the windows.edb indexing file... I also stopped windows search service as mentioned in the comments following the article. In addition to unchecking the "Allow Indexing Service to index this disk for fast file searching" check box on the properties dialog for the C:\ drive, I did the same for two usb connected hard drives (J:\ and I:\ ). I'm not sure why I did that, thought it might shrink the windows.edb file so I wouldn't have to delete it (which sounded a bit risky in my ears at the time). The file of course didn't shrink so I ended up deleting it and freeing up over 3 GB of space, yeehaw. However, as soon as I had done this I could not access the usb connected hard drives anymore. The error I got was "I:\photos is not accessible" "The file or directory is corrupted and unreadable" when I tried to open the photos directory on I:\ Here is where I enter the twilight zone... I try disconnecting I:\ usb hard drive. But XP shows me that instead J:\ drive has disconnected and I:\ is still there. So I disconnect both drives and restart the computer. I then connect one drive, but it lists up the contents of the other drive on root level. I tried connecting the drives vice versa and the same thing happens. I try taking one of the hard drives to another computer and when I connect it there it lists up not its own contents but the contents of the other hard drive and gives the same error as above when I try and access any of the folders (even folders on the root that have the same name as folders on the other drive (e.g. J:\photos and I:\photos)??? And no, this is not a me mixing up my drive letters. Computer Manager - Disk management shows the same result as explorer: The drive size is correct (one is 500GB, the other is 640GB) but the drive name is of the opposite drive, as long as the contents. Also, one drive was full of data and the other almost empty but they incorrectly show their free space status of the other drive. Somehow the usb drives seem to have switched file tables, file records, boot records or something, extremely weird! Even weirder, if I try and create a text file or folder on this drive, it works fine, accessing them, saving, whatever, all good, but accessing any other data on the drive gives me an error. Does anyone have a clue what is going on and more importantly, how I can restore the correct folder listings to access my family photos ??? cheers, linni

• How to grow to be global sysadmin of an organization?

  - by user64729

  Bit of a non-technical question but I have seen questions of the career development type on here before so hopefully it is fine. I work for a fast growing but still small organization (~65 employees). I have been their external sysadmin for a while now, looking after hosted Linux servers and infrastructure. In the past 12 months I have been transforming into the internal sysadmin for our office too. I'm currently studying Cisco CCNA to cover the demands of being an internal sysadmin and looking after the office LAN, routers, switches and VPNs. Now they want me to look after the global sysadmin function of the organization as a whole. The organization has 3 offices in total, 2 in the UK and 1 in the US. I work in one of the UK offices. The other offices are primarily Windows desktops with AD domain shops. My office is primarily a Linux shop with a file-server and NFS/NIS (no AD domain for the Windows desktops yet but it's in the works). Each other office has a sysadmin which in theory I am supposed to supervise but in reality each is independent. I have a very competent junior sysadmin working with me who shares the day-to-day tasks and does some of the longer term projects with my supervision. My boss has asked me how to grow from being the external sysadmin to the global sysadmin. I am to ponder this and then report back to him on how to achieve this. My current thoughts are: Management training or professional development - eg. reading books such as "Influencer" and "7 Habits". Also I feel I should take steps to improving communication skills since a senior person is expected to talk and speak out more often. Learn more about Windows and Active Directory - I'm an LPI-certified guy and have a lot of experience in Linux (Ubuntu or desktop, Debian/Ubuntu as server). Since the other offices are mainly Windows-domains it makes sense to skill-up in that area so I can understand what the other admins are talking about. Talk to previous colleagues who have are are in this role already - to try and get the benefit of their experience. Produce an "IT Roadmap" or similar that maps out where we want the organization to be and when, plotted out over the next couple of years with regards to internal and external infrastructure. I have produced a "Security roadmap" already which does cover some of these things. I guess this can summed up as "thinking more strategically"? I'd appreciate comments from anyone who has been through a similar situation, thanks.

• why can't I open a port on Win 7? is it the app's fault?

  - by rjnagle

  I am having problems opening a port from one Windows PC on my local network. On Windows 7 computer ("Computer A") I running Calibre, an ebook management program that has something called an "ebook content server" . In essence, it serves via the web a content catalog. From Computer A, I can access the content server on localhost. ie. http://127.0.0.1:8787 calls up the content server successfully. With ipconfig I have confirmed that its local IP address is 192.168.1.106 From Computer B (a Vista Machine) I can ping 192.168.1.106 I have tried opening/editing a port in the Windows Firewall several times. In Windows firewall -- Allowed Programs in Control Panel, I see a listing for Calibre (with both Home/Work and PUblic checked) In details, I see Name: Calibre, Port Number 8787, Protocol TCP If I use the Advanced Security configuration screen for the firewall, I created an Inbound Rule on Computer A for Calibre (with the settings I indicated). If I run this command line on Computer A, I see: netstat -a -n TCP 0.0.0.0:554 0.0.0.0:0 LISTENING TCP 0.0.0.0:664 0.0.0.0:0 LISTENING TCP 0.0.0.0:2869 0.0.0.0:0 LISTENING TCP 0.0.0.0:3306 0.0.0.0:0 LISTENING TCP 0.0.0.0:5357 0.0.0.0:0 LISTENING TCP 0.0.0.0:6570 0.0.0.0:0 LISTENING TCP 0.0.0.0:6580 0.0.0.0:0 LISTENING TCP 0.0.0.0:8787 0.0.0.0:0 LISTENING TCP 0.0.0.0:10243 0.0.0.0:0 LISTENING TCP 192.168.1.106:63020 74.125.227.51:80 TIME_WAIT TCP [::]:80 [::]:0 LISTENING TCP [::]:135 [::]:0 LISTENING TCP [::]:443 [::]:0 LISTENING TCP [::]:445 [::]:0 LISTENING TCP [::]:554 [::]:0 LISTENING TCP [::]:2869 [::]:0 LISTENING TCP [::]:5357 [::]:0 LISTENING TCP [::]:6570 [::]:0 LISTENING TCP [::]:6580 [::]:0 LISTENING TCP [::]:10243 [::]:0 LISTENING TCP [::]:49152 [::]:0 LISTENING TCP [::]:49153 [::]:0 LISTENING TCP [::]:49154 [::]:0 LISTENING TCP [::]:49155 [::]:0 LISTENING TCP [::]:49170 [::]:0 LISTENING And lots of other junk, but this seems relevant, I see port 80 is open (I run xampp apache web server for windows on Machine A) This is the only time I see port 8787 referenced from the netstat commmand. From Windows Computer B, I can, ping 192.168.1.106 and even view http://drupal.local (on Computer A) and http://192.168.1.106/ (which goes to the Xampp config screen on Computer A). But I cannot access via Computer B htttp://192.168.1.106:8787 or htttp://computerhosta:8787 So what is going wrong? Is this a problem with the Calibre application or have I incorrectly opened the port? What things could possibly interfere with the opening of this port? On a sidenote, I have tried using telnet from Computer B to see if port 80 or 8787 is open for 192.168.1.106. I get no reply for either one. Thanks.

• Installing Glassfish 3.1 on Ubuntu 10.10 Server

  - by andand

  I've used the directions here to successfully install Glassfish 3.0.1 on an virtualized (VirtualBox and VMWare) Ubuntu 10.10 Server instance without any real difficulty not resolved by more closely following the directions. However when I try applying them to Glassfish 3.1, I seem to keep getting stuck at section 6. "Security configuration before first startup". In particular, there are some differences I noted: 1) There are two keys in the default keystore. The 's1as' key is still there, but another named 'glassfish-instance' is also there. When I saw this, I deleted and recreated them both along with a 'myAlias' key which I was going to use where needed. 2) When turning the security on it seems like part of the server thinks it's on, but others don't. For instances: $ /home/glassfish/bin/asadmin set server-config.network-config.protocols.protocol.admin-listener.security-enabled=true server-config.network-config.protocols.protocol.admin-listener.security-enabled=true Command set executed successfully. $ /home/glassfish/bin/asadmin get server-config.network-config.protocols.protocol.admin-listener.security-enabled server-config.network-config.protocols.protocol.admin-listener.security-enabled=true Command get executed successfully. $ /home/glassfish/bin/asadmin --secure list-jvm-options It appears that server [localhost:4848] does not accept secure connections.

  I'm trying to install Lync server 2010 but i'm stuck for a while now with the "Active Directory Preparation" part of the Lync server 2010 installation. The "Prepare Schema" fails with the following error: "Step 1: Prepare Schema Run once per deployment. Extends the schema for Lync Server.

If I check "Active Directory Users and Computers" and go to the directory Users and watch the properties from the Administrator User then it is also a Member of: Domain Admins Domain Users Enterprise Admins Schema Admins Group Policy Creator Owners The firewall on the server2008 is turned off, still nog working So now my question is: what should I do to make the Lync setup (Active Directory Preparation) work? (I would appreciate clear step-by-step suggestions to check.) Thanks in advance. Update 1: Now I've extended AD successfully on the 2003 DC, using this link: http://blogs.pointbridge.com/Blogs/sloan_jason/Pages/Post.aspx?_ID=2 but when I check the Active Directory Preparation again on the Lync install, it still gives me the same error as in the screenshot I've provided. Update 2: I found out that there is a log on "C:\Users\\AppData\Local\Temp\ with this: Get-CSDomainState Get Domain State Error: An error occurred: "Microsoft.Rtc.Management.ADConnect.NoSuitableServerFoundException" "No suitable domain controller was found in domain "OurDomain.LOCAL". Errors:\r\n"OurDCserver.OurDomain.LOCAL5.2 (3790)5.2 (3790) Service Pack1OurDCserver.OurDomain.LOCAL5.2 (3790)5.2 (3790)Service Pack 1"" I thought Lync could be installed with a Windows Server 2003 (according to the documentation on technet) and it doesn't require a SP. :s

• What are some of the best wireless routers for a price-conscious home power-user?

  - by Alain

  I'm extremely dissatisfied with the 'popular' choice for routers in homes and small offices. They are expensive (upwards of 60$), lack a great deal of useful configuration options, and seem to need to be restarted quite often. (Linksys comes to mind). I've been on the market for a good router lately, and slowly collecting a set of requirements I feel good routers should meet. Maximum number of TCP/IP connections. - This isn't something I see any routers advertise, but in terms of supporting torrent applications, I've been screwed by routers that support less than 20 here. From what I understand a fairly standard number is 200, but there are not so expensive routers that support thousands. Router configuration menu - Most have standard menu's that let you set up basic things like your wireless network encryption settings, uPnP, and maybe even DMZ (demilitarized zones). An absolute requirement for me, however, are routers with good enough firmware to support: Explicit Port forwarding Assigning static local ips to specific mac addresses, or at least Port forwarding by MAC address Port, IP and MAC filtering Dynamic DNS service for home users who want to set up a server but have a dynamic IP Traffic shaping (ideally) - giving priority to packets from certain machines or over certain ports. Strong wireless signal - If getting a reliable signal requires me to be so close to the router that I can connect an Ethernet cable, it's not good enough. As many Ethernet ports as possible. - Because I want to be able to switch from console gaming to PC gaming without visiting my router. So far, the best thing I've stumbled upon (in the bargain bin at staples) was a 20$ retail plus router. It was meant to be the cheapest alternative until I could find something better to purchase online, but I was actually blown away by the firmware capabilities. It supports defining reserved bandwidth for certain network traffic, dynamic DNS, reserving local IPs for specific MAC addresses, etc. At 2 am when my roommate is killing our Internet with their torrents, I can limit their bandwidth without outright blacklisting them. I have, however, met serious limitations when it comes to network traffic between local machines. It claims a 300Mbps connection, but I have trouble streaming videos from my PC to my console or other laptops wirelessly. It has a meltdown and needs to be reset once in a while (no more than a couple times a month), and it's got a 200 connection limit. There 4 Ethernet ports in the back but I'm pretty sure the first doesn't work. So some great answers to this question would be: Any metrics you use to compare routers, and requirements you have for new candidates. The best routers you've found for supporting home servers, file management systems, high volume torrent traffic, good price/feature ratio, etc. Good configuration advice (aside from 'use Ethernet whenever possible') Thanks for your feedback and experiences!

• My server freezes within a few hours of logging out. Staying logged in keeps the server running

  - by HappyEngineer

  I have an Ubuntu Godaddy server I use to host mail and webapps. It started having problems a couple months ago. It would lock up and stop responding to anything. I couldn't ssh into it, so I'd have godaddy power cycle the server. I have never seen anything that looked suspicious in the var logs (although I'm no expert at reading them). An fsck turned up no problems. Godaddy replaced the ram, but found no hardware problems. I started logging the output from "top" to a log file and found that even that stops running when the server freezes. Now, here is the crazy part: It got so bad that it would actually go down every few hours, but then it stopped going down. I eventually realized I had left an ssh terminal logged into the machine running top. This seemed unlikely to be a reason, but after the server was up with no problems for a full week (remember, it had been going down after just a few hours), I disconnected from the ssh session. Lo and behold, within a few hours the server froze again! I had them power cycle again and then left another ssh session open with top. It has been going without problems for 8 days now. I told others about this and they hardly believe me. I simply can't imagine what is going on. I don't know what else to try other than to just get a new server and reinstall everything. Does anyone have any ideas about what I can look for to determine what the cause is? Is it possible there's some sort of exploit on the server which only runs if everyone is logged out of the system? EDIT: The power management gone haywire sounds plausible, so I've modified the /boot/grub/menu.lst to boot with acpi=off and apm=off. It appears to have prevented kacpid and kacpid_notify from being in the process list, so I assume I did that right. I've disconnected all my sessions from the server. I'll check later tonight to see if it's still up. If it goes down then I'll try the pinging process idea. EDIT: It went down again. It lasted about a day. I've had them reboot, so now I'll try running "nohup ping -i 5 google.com &" and then disconnect. If it goes down again I'll come back. Hopefully someone will have some more ideas.

• Encrypted off-site data storage

  - by Dan

  My business has a rather unique problem. We work in China and we want to implement a file server paradigm which does not store any files locally, but rather in a server overseas. Applications would be saved onto our local machines, but data would be loaded directly into memory from the cloud, e.g. I load a docx into word at the beginning of the day, saving periodically to the cloud as I work on it, and turn off my computer at night, with nothing saved locally. Considering recent events, we worry about being raided by the Chinese authorities, and although all our data is encrypted, it would not be hard for the authorities to force us to give up the keys. So the goal is not to have anything compromising physically in China. We have about 20 computers, and we need an authenticated, encrypted connection with this overseas file server. A system with Active-Directory-like permissions would be best, so that only management can read or write to certain files, or workers can only access files that relate to their projects, and to which all access can be cut off should the need arise. The file server itself would also need to be encrypted. And for convenience, it would be nice if this system was integrated with each computer's file explorer (like skydrive or dropbox does, but, again, without saving a copy locally), rather than through a browser. I can't find any solution online. Does anyone know of a service that does this? Otherwise I'll have to do it myself (which kinda sounds fun, but I don't really have the time), and I'm not sure where to start. Amazon maybe. But the protocols that offices would use on their intranet typically aren't encrypted; we need all traffic securely tunneled out of the country. Each computer already has a VPN to a server in California, but I'm unsure whether it would be efficient to pipe file transfers through it. Let me know if anyone has any ideas. And this is my first post; feel free say whether this question is inappropriate/needs to be posted elsewhere.

• Certain clients (IP range) can not ping server

  - by Logman

  I just virtualized a Windows 2003 Server SP2 x32. The server contained our help desk server (Spiceworks) and our anti virus management server (ESET RAC). The host computer actually contained the virtualized server originally; I created the vhd and then I wiped this system clean and installed Windows 2008 R2 x64 Datacenter and added the virtualized 2003 onto the Hyper-V 2008 R2 Server. I got the server running fine except for... certain ip ranges. Local clients can get updates from the AV server from my 192.168.180.xxx & 192.168.181.xxx BUT NOT from any 192.168.182.xxx, 192.168.183.xxx, 192.168.184.xxx etc... I can not ping the server from any clients except for the 180. & 181. ranges. Now I created 2 other virtualized servers (win2008 & a win7 pro) and they exist on the same virtual host as the 2003 server. And at first I could not ping those until I went to the "\Network and Sharing Center\Advanced sharing settings" and Turned On File and Print Sharing. Then I could ping and access those virtualized guests. Win2003 server isn't quite the same. But I am sure I have it on. But now when I ping from a client on one of those ranges that would not work I get this: As you can see the ping leaves our network. We have 2 ad/dns servers (one 180. & the other in the 181. range). Is it DNS? Both AD/DNS servers are Windows 2003. And we plan on upgrading both to 2008 R2 within a month or two but I need to fix this issue pronto (esp the AV end). btw, I did rename that 2003 Server (Spiceworks/AV) hostname. And I tried a CNAME. But I do not think that is the problem. EDIT: OR because this server existed on this hardware/computer before becoming virtualized?
