• Migration with SysPrep, ImageX and

  - by Jack Smith

  I know that you can use SysPrep and ImageX to create a prepared image that can be used on several systems but the question is. How well does it work in a corporate environment of moving machines from old hardware off to new harddrives and new hardware? EDIT: The system runs accounting software and databases. So would SysPrep remove all License keys and other information which means would cause problems right? Would something else be a better option even though there are heavy costs involved? Currently, when I clone/copy the drive, Windows will black screen on me. So I need something with differential hardware support?

• Stack , data and address space limits on an Ubuntu server

  - by PaulDaviesC

  I am running an Ubuntu server which has around 5000 users. The users are allowed to SSH in to the system. So in order to cap the memory used up by a process I have capped the address space limits using limits.conf. So my question is , should I be limiting the data and stack ? I feel that is not required since I am capping address space. Are there any pitfalls if I do not cap the stack and data limits?

• Keyboard automatically disconnects and reconnects

  - by Algorithms

  The problem i am facing is the keyboard (USB) automatically disconnects when there is a fluctuation in the power supply to the speaker. The speaker and the pc both draw power from a apc ups. The fluctuation occurs because the speaker plug is not tightly connected to the ups power outlet. It is okay for normal work, but a accidental jerk causes the fluctuation. However after some amount of time (usually within 5 seconds) the keyboard automatically reconnects and windows plays the sound of hardware connected. This problem will also occur if I manually take out the speaker power cable from the ups power outlet. My question is whether the problem I am facing is due to electrical issues, or due to software problems. PC config: OS : Windows 7 Ultimate UPS : APC 600 VA PSU : Corsair TX 650 Speaker : Realtek

• Acer Aspire ASE700-UQ660A will not respond to power button

  - by Tim R.

  This is something of a continuation of this question. I am now completely unable to boot this computer. The last time I used it, I used hibernation mode. When I needed to use it again, it would not respond at all to the power button, keyboard, or mouse. I tried: Holding down the power button for 15 seconds pressing the power button Unplugging the power cord for 30 seconds, plugging it back in, and trying again Removing the motherboard battery for over a minute and reinstalling it Before removing the motherboard battery, none of the lights on the front of the computer lit up. After reinstalling the battery and plugging the power cord back in, the light behind the power button is constantly illuminated (without even pressing the power button), but there is still no response to the power button, no fans turned on, nothing else that would indicate that it is running. System: Acer Aspire ASE700-UQ660A (Specs should be all factory defaults except:) 4 GB RAM Nvidia GeForce 8600 GT with driver version 197.45 Windows 7 Professional 64 bit

• puppet duplicate resources and virtual resources

  - by user45097

  Overview Hi just started using Puppet and have been unable to suss something. Problem Because of normalization when I add 2 classes to a node with packages that have the same dependencies it fails. In simple terms have duplicate resources - in this case the package libssl. Note: packages are being held to prevent latest packages being installed. QUestion What's the best practice way to get round this? class ssh { package { 'openssh-server': ensure = installed, require = libssl } package { 'libssl': ensure = installed, } } class apache { package { 'apache': ensure = installed, require = libssl, } package { 'libssl': ensure = installed, } } node server { include apache include openssl-server

• Windows CA to issue certificate to authenticate SSH to a Linux server

  - by BArnold

  I have a Windows Server Root Certificate Authority, Linux SSH server, and users with Windows SSH clients. The Linux box is not part of the AD domain (and probably never will be [sigh]) OpenSSH 5.4 and above supports X.509 certiicate based authentication. I am trying to find a way to use my Windows Certificate Authority to issue certificates for authentication of the users when the SSH to the Linux box. I do not want to have to generate a keypair on each user's desktop. And we want the certificates controlled and revokable at the Windows CA. My question is not exactly the same as SSH from Windows to Linux with AD certificates (and the referenced moelinux.net seems to be down) I have searched Google a lot, and haven't found much results about how to accomplish this. An answer doesn't necessarily have to include a full tutorial, even some hints about what to search on or pointers to some references may be helpful.

• Windows 7 MSDN version

  - by Larry Branham

  I recently purchased a copy of Windows 7 online. Upon trying to install, it stopped and I was told that it could not find a 64 bit driver for my CD/DVD and I could not finish install. I contacted Microsoft and was told that this was something called an MSDN version according to the product key and that was the reason for the problem. They also said is was illegal to sell it to me. The company I bought it from never returned my calls or emails and luckily I got money back through Amazon. Amazon didn't even want me to send it back. Anyway my question is, is there anyway to load this onto my system and will I have problems or should I just throw it out? Any help would be great. Thanks

• Syslog - capturing event logs from Win2k boxes

  - by molecule

  Hi all, I asked this question in SuperUser without much luck and so I am posting it here to see if anyone can assist. We have a central syslog server and we want it to capture event log events from Windows hosts. We are specifically interested in logging service start/stop events. We installed "Eventlog to Syslog" on these windows hosts and all works well with XP hosts (Events come from Service Control Manager). However, we are having issues with Win2k hosts. For some reason, service start/stop events do not get logged in the Event Log for Win2k hosts. I got another friend from another company to test on a Win2k host and he does get start/stop events on them. I have searched around for local audit policies i need to enable but with not much luck. Anyone have any ideas? Thanks in advance.

• Connecting to VPN via Proxy

  - by Rodrigo

  Hi, My company's VPN server is located in Netherlands, from my current location this is a really crappy place in terms of connectivity, connection keeps dropping, it's slow and keeps being reset during high traffic times. I have a dedicated server over USA which is able to connect to VPN server without this issues, connection is stable and fast. My question is, how do I connect to this VPN using a proxy running on my dedicated server? I'm on Windows 7 using a VM on XP to connect to the VPN. Thanks.

• Anonymous user permission issue in SharePoint Server

  - by George2

  Hello everyone, I am using SharePoint Server 2007 x64 and Windows Server 2008 x64. I have setup a site with template publishing portal. I have grant anonymous access to all the site. My question is, if I create a new page, how to grant permission to anonymous user to access (read permission) the page? I got this confusion because, for the permission setting of a page, a permission is set according to a user name (e.g. read permission for user "foo" of a page). Since anonymous user does not have a related "user name", how could I grant read permission to anonymous user? BTW: I use Windows Forms authentication and Windows NTLM authentication for my sites. Thanks in advance, George

• Upgrade MySQL on Plesk on Windows

  - by Cyril Gupta

  I just got a nasty surprise when I installed a website in Unicode Hindi (Indian language) on a server, all freshly entered unicode data is turning into question marks on the server. On my dev machine it works perfectly. I found that I have MySQL version 5.0.45 (installed in default by Plesk I guess). On my dev machine i have version 5.1.33. I believe the problem could be due to the version difference. The new version of MySQL apparently has better support for Unicode than the older one. I want to upgrade MySQL on my Windows Server machine with Plesk installed on it I am reluctant to just install the new version using the mysql installer because Plesk maintains some custom settings for mysql and I am afraid the new version could change those settings and break my db. Can anyone tell me do I have to do anything special to install MySQL on plesk on windows or can I just use the new version installer?

• Can my laptop run dual 1080p (Sony Vaio - Nvidia 330M)

  - by Charlino

  I am looking to buy a monitor to setup dual monitors for my laptop and was wondering if my laptop could handle 2 x 1080p. I have a Sony Vaio VPCF116FG which has a Nvidia GeForce 330M chip and 1GB dedicated graphics memory. The laptop also has a Intel® Core™ i7-720QM Processor (1.60 GHz with Turbo Boost up to 2.80 GHz) but I don't know if that's relevant(?). The laptop screen has a native resolution of 1080p (1920 x 1080) so I'll be looking at buying a external monitor with 1080p to connect up using a HDMI cable. So, the question is, will my laptop be able to handle it's own 1080p screen AND an external 1080p screen? TIA, Charles

• Forgot Microsoft Virtual PC's password

So, while I can continue to work now, if I were to lock the computer or shut it down, I am locked out. Questions How can I ensure that the Virtual PC automatic lock does not happen? (Giving me time to try and remember the password or for future users, to look up this question!) How can I find out/reset my password?

• Ubuntu whois package and request limits

  - by Sam Hammamy

  I'm writing a django app with a form that accepts an IP and does a whois lookup on the discovered domain names. I've found the Ubuntu package whois which I plan to call from a python subprocess, and read the stdout into a StringIO, then parse for things like Registrar, Name Servers, etc. My question is, it seems that there are many paid whois services, which means that there must be a reason why people don't just use this Ubuntu package. I'm wondering if there's a request limit on the number of requests from a single IP to the package's whois server? I will probably be making 250 domain lookups per IP or maybe more. Also, I've found that some domains aren't searchable: qmul.ac.uk is searchable kat.ph is not searchable ahram.org.eg is not searchable Any particular reason for that?

• Should I use my ISP's DNS, or Google's 8.8.8.8?

  - by Torben Gundtofte-Bruun

  It seems like a good idea to use Google's public DNS 8.8.8.8 and 8.8.4.4 because it's really fast -- much faster than my own ISP's DNS! -- and probably more reliable, too. That seems like a ridiculously quick win for me, and much easier to remember. Assuming we're not all "tin foil hat" about Google, why shouldn't everybody use Google DNS? Note: I've seen this question, but I don't want a comparison to OpenDNS. This is about everyday use by everyday people in their homes. Update: I seem to have put my hand in a wasps' nest of privacy concerns. I appreciate the issue, but I was expecting a more technology-oriented discussion...

• Selinux interfering with vboxwebsrv or phpvirtualbox

  - by Mike W

  I have a brand new installation of Fedora 18, with a brand new installation of Virtualbox 4.2. I have spent a painful few hours trying to get phpVirtualBox working. Apache 2.4 and PHP 5.4 are installed, along with the phpVirtualBox software. Attempting to access phpVirtualBox allowed me to login, but then I'd have a prolonged wait until an 'Error fetching HTTP headers' message appeared. Finally, I set SeLinux to permissive, and Bingo! things start to work. For some reason the SeLinux Troubleshooter isn't flagging any messages from SeLinux, I don't know what to look for now. This is a development box so I could leave SeLinux set to permissive but I will need to make this work in anger on the next project. My question, then, is this: What changes to SeLinux policies do I need to make to allow phpVirtualBox and vboxwebsrv to work together? If there's more information I can post that will assist I'll gladly post it - just let me know what it is.

• Can't set 1280x1024 on Ubuntu with Nvidia Geforce 8400 GS

  - by torbengb

  Ubuntu doesn't offer 1280x1024 but that's what my monitor has -- I want to set that resolution but need help doing so. Ubuntu offers 1360x768, 1152x864, 1024x768 when using the Nvidia driver version 180. This is Ubuntu 9.04 installed as "Wubi" through Windows, I believe it's the amd64 version. Google gave me this precise explanation which is complete latin to me; I'm a Windows guy and not familiar with Terminal. These SU questions also don't provide answers, hence this new question. I hope you can help, and I will provide additional info if required.

• Windows Server 2012 & Exchange Server 2013 CAL's

  - by Joey Harris

  Trying to build an Exchange server solution for a company and they want me to look into licensing for Windows. I'm going to be purchasing the necessary server licenses for Windows Server 2012 Standard and Microsoft Exchange 2013 Enterprise. I just have a few questions about the CAL's thing which seems like a complete ripoff to me. How are CAL's tracked for both Windows Server and Exchange? Is it tied to Active Directory profiles? What happens if I dont have the necessary CAL's for Windows Server? Will a client be denied access from Active Directory? Is there any enforcement for this? Also the same question for Exchange 2013 CAL's Thanks

• Merit and demerits for various Linux fiberchannel multipath options

  - by wzzrd

  On our Linux servers, we currently use HPs qla2xxx drivers, because it has multipathing (active/passive) built in. The are, however, various other options, like Red Hats device-mapper-multipath with the stock qla2xxx drivers (multibus and failover) and things like SecurePath and PowerPath (both of which can do trunking, iirc). Can someone tell me what the merits and demerits of the various options are (if I can ask such a question), besides the obvious fact that the {Secure,Power}Path options cost vast amounts of money? I'm mainly interested in the freely available options, like HPs qla2xxx vs. Red Hats multipathd and possible other open source solutions, but I would like to hear good reasons to go for the commercial solutions too. UPDATE: I'll be benchmarking various options the coming few days (the average of 10 runs of iozone for each option (options being native qla2xxx failver, native qla2xxx multibus, HP qla2xxx failover)). I'll post a summary of results here for those interested.

• How to add authentication to ssh dynamic port forwarding?

  - by Aalex Gabi

  I am using ssh as a SOCKS server by running this command on the server: ssh -f2qTnND *:1080 root@localhost There is one problem: anybody can connect to the server and use it's internet connection. Options: To use iptables to filter access to the server, but I connect to the server from various non-statically allocated IP addresses so I would have to edit very frequently those filters which can be annoying. To install a SOCKS server on the remote. Ultimately this is the last option if there is no other simpler way to do it. (I am very lazy) Launching the same command on clients machines. The problem here is that some clients don't run on Linux and it is awkward to set up the tunnel (Windows + Putty). Is there a way to add authentication to a SOCKS server made using ssh? Bonus question: How to add encryption between the client and the server (made using ssh)?

• Windows 2008R2 blocks outbound LDAP for non-admins?

  - by Jon Bailey

  I've got a Windows 2008R2 terminal server with ~30 users on it. It's joined to a Samba-based domain. During the login script, we connect directly to the LDAP server to pull out certain profile information. This used to work just fine. Now, it doesn't, but only for non-local-admin accounts. Local admins work fine. As a non-local-admin: Connection to ports 389 or 636 just terminate (wireshark on the LDAP server reveals no connection attempt) Connection to other ports on the same server work fine Same thing on multiple LDAP servers Windows firewall is disabled Can't find any other rules/policies that may block this I suspect since this used to work, it came down during an update, but for the life of me, I can't find what. EDIT: I just ran Wireshark on the machine and didn't see anything when connecting to the LDAP server in question (or any LDAP server for that matter). I can, however, see traffic when I connect to that server on another port.

• Ubuntu: How to login without entering username and password

  - by torbengb

  I'm a newbie running Ubuntu 9.10. I have two users (wife and me), and each user's screensaver is set to lock so that on wakeup, we get to choose which user's desktop to go to. However, Ubuntu requires a password, so this is pretty tedious. I'd like to switch users without entering any password. I know about this trick that works for the boot login, but it doesn't deal with multiple users. Is it possible to set empty passwords for users in Ubuntu, or skip the password in other ways? (I'm expecting real Linux users to suggest that passwordless users must not get any rights and there be an admin user with a strong password. Yes, you're right. But that's not what this question is about. Thanks.)

• Cannot resize OS X partition

  - by David Pearce

  I am trying to resize my existing Mac OS Extended partition on my Macbook to install Windows 7 (using steps similar to these), but when ever I go to apply the changes, I get this error: Partition failed Partition failed with the error: The partition cannot be resized. Try reducing the amount of change in the size of the partition. The total capacity of the hard drive in question is 260GB, with the entirety being taken up by the OS X boot partition. There is I am aiming to shrink that partition down to 60GB. How can I fix this problem? I have been reducing the amount of change by 10GB each attempt, but it still is not working. I assume the problem is that there is not a large amount of continuous space on the device. Is there some way to can do a manual defrag that would rectify this problem?

• How do you enable syslogd to accept incoming connections on Snow Leopard from remote loggers?

  - by Emmel

  How do I get syslogd to accept incoming connections from remote hosts on Snow Leopard? I'd like to centralize logging such that various devices and systems send logs to Snow Leopard's syslogd, which normally hangs out on UDP 514. However, I'm unable to get them to successfully be accepted by good ole syslogd. I tcpdumped on the Snow Leopard box to verify that packets are being spouted to port 514 -- they are. I checked that syslogd is listening on 514 -- it's not. Googling around told me that, on older versions of OSX (don't you love the way things change so rapidly on OSX), one just had to add a flag to the syslogd daemon to allow remote; one did this in com.apple.syslogd.plist. However the syslogd daemon has no flags (at least in its man page) that suggests any remote anything. What's the solution to this? Secondary, less import but relevant question: What's 'newsyslog'? I see a plist file but it's not running (apparently). Thanks
