• SQL Server Files Local or NAS or SAN?

  - by Jedi Master Spooky

  I have to install a new Server with SQL Server 2008, What do you recommend, One server with Raid 10 or the Files in a NAS? What about iSCSI should I use it? What about SAN? The server has 4Gb of RAM and that database file is about 2GB. To make my self clear today the server has no RAID, I have to implement some kind of strategy so if something happend I can have my files safe, so What should I choose Local Files, NAS, SAN? What option has the most performance, what is the more secure?

• Suscribers locking during snapshot replication

  - by remi_bourgarel

  Hi all :) Here is my architecture : I have a main server and 4 replica (the servers are synchronized with snapshot replication). The replication is working fine, except for one thing : during the replication a lot of SELECT request on one of the replica fail with a time-out. Here are my questions : Can I avoid these time-out ? If I can't : how can I detect the start and the end of the replication to redirect all the request on one of the replica to the main ? Thanks Sorry if you already answered to that kind of question but I couldn't find anything.

• How do I convert this filetype to pdf?

  - by Gnoupi

  This question is coming back often, and the general answers are very often the same. In an objective to concentrate useful information in one place, here is a community wiki about it. How can I convert this filetype to pdf? This question will have two kind of answers: The generic case, which works for most filetypes. The specific cases, which should be one answer per filetype. Restricting the OS field to Windows, as most of these questions are about this OS. This may change eventually. As it is community wiki, feel free to edit this question to improve it as well.

• how to change document root to public_html from root directory

  - by manish

  For testing I hosted my website on free server from 000webhost.com They have a directory structure:- (root folder) \ (public folder) \public_html this directory structure enables to keep all the library files in root folder and all public data in \public_html, so I developed my website accordingly, and my final structure looked like:- / /include(this folder contains library files) /logs(log files) /public_html /public_html/index.php /public_html/home.php /public_html/and other public files on 000webhost makes only public_folder available to be accessed via url and my url looked neat and clean like www.xample.com/index.php or www.example.com/home.php but after completion of development I moved website to shared host purchased from go-daddy.com, now they do not have any such kind of directory permission, all the files are kept in root folder and are accessible via url also url has become like:- www.example.com/public_html/home.php or www.example.com/public_html/index.php How should I redirect url request to public_html folder again so as to make library file unavailable to public access and make url neat and clean.

• Sql Server differential backup : Simple vs Full recovery model

  - by MaxiWheat

  I need to better understand the backup process under SQL Server 2008. Since drive space is a kind of matter for us and we want to have a better disaster recovery solution, I decided that we will implement differential backups throughout the day (every hour). Am I right to think that if I keep the recovery model of my databases to Simple, the differential backup will be almost the same size as Full Backup (too big to make one every hour) ? I already tried to switch to Full recovery and it seemed to have fixed the issue (differential backups were way smaller). I heard that the recovery model must be set to Full to use Log backups (to the minute recovery etc., but we don't need that) but never about differential backups. So, is the recovery model really having an impact on differential backups or am I missing something ? Thank you

• SYN flooding still a threat to servers?

  - by Rob

  Well recently I've been reading about different Denial of Service methods. One method that kind of stuck out was SYN flooding. I'm a member of some not-so-nice forums, and someone was selling a python script that would DoS a server using SYN packets with a spoofed IP address. However, if you sent a SYN packet to a server, with a spoofed IP address, the target server would return the SYN/ACK packet to the host that was spoofed. In which case, wouldn't the spoofed host return an RST packet, thus negating the 75 second long-wait, and ultimately failing in its attempt to DoS the server?

• How can you control the speed of fan that comes with the Antec Sonata III case from the outside?

  - by Emil Lerch

  The Antec Sonata III case comes with a nice 120mm fan that has a 3 speed switch. Most of the time the fan is fine on low, but for games or other taxing workloads I need to switch it to medium or high. Opening the case every time I want to change the setting is kind of a pain. Has anyone figured out a way to control the speed from the outside of the case without going nuclear (e.g. cutting holes in the case)? Other than this annoyance I like the case and the fan that comes with it.

• Autoinstall of Microsoft Security Essentials give random error message

  - by vegarwe

  I'm using wpkg to auto install Microsoft security essentials on WinXP. At the first login after the installer finishes I get an error message as msseces.exe starts. After a reboot the message goes away. The error message indicates a random access restriction. "An error has occured in the program. Try to open it again. If this problem continues, you'll need to reinstall Microsoft Security Essentials from the Microsoft Download Center. Error code: 0x80070005" Firstly: Does anyone know why I get this error message? Second: How do I debug this kind of problems? The event log doesn't seem to contain anything useful. Is there a tool to detect and list denied system calls?

• shibboleth: tomcat failing to start IdP listener

  - by HorusKol

  I have installed a Shibboleth Identity Provider as per http://www.edugate.ie/workshop-guides/shibboleth-2-identity-provider-installation-linux-debian-or-ubuntu However, testing only gave me a 404 from Tomcat, and when I checked the Tomcat logs, I saw that the IdP listener was not starting: 10/01/2011 11:25:31 AM org.apache.catalina.startup.HostConfig deployDescriptor INFO: Deploying configuration descriptor idp.xml 10/01/2011 11:25:32 AM org.apache.catalina.core.StandardContext start SEVERE: Error listenerStart 10/01/2011 11:25:32 AM org.apache.catalina.core.StandardContext start SEVERE: Context [/idp] startup failed due to previous errors The IdP descriptor file has the following context: <Context docBase="/opt/shibboleth-idp/war/idp.war" privileged="true" antiResourceLocking="false" antiJARLocking="false" unpackWAR="true" /> I have confirmed that the WAR file is located as the Context above specifies - as I have found similar issues from other people where the WAR file was not found. However, the logs posted by those people indicate that the descriptor file was correctly read by Tomcat and their problem was with the WAR file itself. I'm assuming this is some kind of syntax error with the idp.xml, but cannot determine what it might be. Also - setting the Tomcat logging level to FINEST does not provide any additional information in the logs for this error.

• What could explain my partitions disappearing on a new SSD with Windows 7?

  - by charlesrandall

  So this morning, I had a fresh install of Windows 7 pro, on a new SSD (Patriot TorqX 128gb), which I just put in to a new Dell Studio XPS 9000. Everything was fine. I booted to windows, no problem. I go to work. 8 hours later, I come home, and I'm greeted by my boot screen complaining about no bootable devices. Windows repair from the Windows 7 pro disk says it can't fix the problem. It doesn't see any windows installs. I boot up GParted, and my SSD is completely unallocated. No space used, no partitions. Perhaps this is related to allowing windows 7 to create a utility partition when I installed? Only thing I can think of. Is there some kind of known hardware issue that can result in an SSD completely wiping itself?

• Cheapest Embedded System with Wireless Connectivity?

  - by geeko

  Problem: I'm trying to capture some information coming from keyboard, mouse and barcode reader connected to some PC via PS/2, USB and/or RS-232, before information get to PC and send it over the Internet to some central server. I'm thinking to do so by using some kind of hardware interface (middleware, if you like) between PC and input devices. I thought this interface can be embedded PC, PDA or simply some mobile phone with wireless connectivity. PS/2 and RS-232 could be converted to USB using some USB convector/hub that connects to one of these interface systems. Then some special API programming take place to communicate between PC, input devices and wireless server, in the form of application running on the interface system. What's the cheapest solution that can achieve this? Or possibly any other solution?

• Corporate IM with video that actually works, suggestions?

  - by Erik P. Skaalerud

  Hi. Does anyone here have a suggestion for a cross-platform IM solution wich will work with voip/video on both Windows (XP and 7) and Mac OS X from 10.4 and upwards? Right now were in a kind of mixed enviroment, with some Mac users using iChat server since they need video support (conference across several offices over VPN), but it wont't work on windows clients. The rest of us are happily using Openfire+Spark, but there's no VoIP or video avaible from what i've found, unless you want to add in several 3rd party software (like red5 and asterisk). Requirements: As said before; must work on both Windows and Mac Internal server (no Skype etc) File transfer between platforms SSO (Single Sign-On) via Active Directory authentication Some sort of screen sharing would be a plus, like switching over to a screen capture (powerpoint, software training etc) We can afford to buy software if that's needed to get this working without any hiccups across platforms. Pre-thanks to anyone who gives suggestions.

• Microsoft Outlook x Lotus Notes in enterprise environment

  - by Ladislav Mrnka

  I'm working in company (several thousands client computers) using tools like MS Outlook + Exchange + Sharepoint + Communication server. Now our mother company shared the idea that everything should be moved to IBM Lotus Notes + Domino. The reason for this is that Outlook based solution is too expensive (it is the official statement even they don't want to replace MS Office yet). Other reason probably is that they received a lot of licences for Lotus when they bought IBM servers to new data center. My question is: Is this reasonable change or is it just some management game and IBM's marketing? Will it really save money? Other question: Is Lotus better then MS solution? This is serious question, it is not mentioned to open any kind of flame war. I just don't believe the decission and I have never used Lotus tools.

• Can't make updates with LDAP from Linux box to Windows AD

  - by amburnside

  I have a webapp (built using Zend Framework - PHP) that runs on a Linux environment which needs to authenticate against Active Directory on a Windows server. So far my webapp can authenticate with LDAPS, but cannot perform any kind of write operation (add/update/delete). It can only read. I have configured my server as follows: I have exported the CA Certificate from my Windows AD server to /etc/opendldap/certs I have created a pem file based on this certificate using openssl I have update /etc/openldap/ldap.conf so that it knows where to look for the pem certificate: TLS_CACERT /etc/openldap/certs/xyz.internal.pem When I run my script, I get the following error: 0x35 (Server is unwilling to perform; 0000209A: SvcErr: DSID-031A1021, problem 5003 (WILL_NOT_PERFORM), data 0 ): Have I missed something with my configuration, which is causing the server to reject making updates to AD?

• How can I add autocomplete in notepad++ for javascript in an .html file?

  - by Nikhil

  Notepad++ does auto-complete for html and also for JavaScript. but the auto-completion depends on file extension.html file supports completion for html only. Is there a way to enable auto-completion for javascript in the script tag of an html file? I mean, other than copying the auto-completion keyword list from "javascript.xml" to "html.xml" files... As suggested on stackoverflow, asking on superuser, as I could not find a satisfactory answer there. If anyone has any idea, please let me know! (I hope I am not the only one having this kind of an requirement! :))

• Hardware needs for video conversion server

  - by artaxerxe

  I would need to build a Linux server that will have as its main task to perform the video conversion. For video conversion, the most likely I will use FFMpeg tool. Question: Can anyone tell me if for improving this automated video conversion a video card will improve the process or not? The idea is that I will get movies at a very high quality that I will need to be converted in formats available for different devices (iPhone, iPad, etc.). That conversion will be performed through a CLI (command line interface). I will need that conversion to be done in the least time possible (ok, that's a kind of saying, not an absolutely specified short time).

• How can I limit CloudFront downloads

  - by Alex Crouzen

  I'm looking to use Amazon's CloudFront to host some content in the near future. Currently, I'm keeping it very simple and I'm just uploading my content to S3 and then making a distribution available via Cloudfront. However, because I have a limited budget, I'd like to be able to limit the number of downloads or the money spent on bandwidth. As far as I can see, I can't set any quotas or budgets like you can in Google's App Engine, so I'm looking for another way of doing this. Has anyone had any experience doing this? One approach I'm thinking of is having to place a webserver with redirects in between, but that kind of defeats the simplicity of CF for me.

• Data drive disappearing.

  - by Mike Keller

  We have a Windows 2003 R2 server with SP 2 here that randomly loses a partition. There are two partitions the C: and the D: (the one that disappears). When I go into Disk Management the space shows available on the drive but that it isn't formated. There are two drives that are set up in a RAID 1 array. There isn't anything sticking out in the event log as to something triggering this problem and thank god we do daily backups of the data, but it gets kind of annoying to have to go back in there and reformat the partition and restore the data. Any places I can poke around to find the cause of this or even better solutions to the problem would be appreciated.

• Video compression artifacts in Flash

  - by lvanderhart

  This only started happening in the past two days, which seems very odd to me. Everything worked flawlessly up until now, and I use my my computer as my primary TV. Flash video from Hulu and Amazon, for no apparent reason, now have lots of artifacts in them. Some scenes are ok, but some are completely scrambled and unwatchable. My connection is a 15mb fios, and bandwidth tests indicate my connection speed is ok. I've tried the latest production version of Flash, as well as the 10.1RC4. Same problem. Enabling or disabling hardware acceleration in Flash makes no difference (with the scrambling issue, quality is better overall with hardware). Using a different H264 codec doesn't clean up the issue, although the scrambling does look different. I'm kind of stumped. The only thing I can think of now is to reinstall windows, which is obviously a drastic step. Edit: Forgot to say: Windows 7, Athlon 64X2, Geforce GTS 250

• What is better to have more LUNs or more Storages

  - by skomak

  Hi, what is better to have - more LUNs or more Storages. Actually i have 1 storage ESXi per 1 LUN so there are about 15 LUNs and 15 storages. Now there is a kind of problem because the LUNs have different space allocated so if i remove 2 LUNs f.e. 1 2 3 4 [x] 6 [x] 8 9 (like that) i can't make 1 LUN from 5 and 7 pieces of free diskspace on IBM storage array. It's a first argument to not have a lot of LUNs. If i had to make only a few LUNs (about 3) and inside some Storage from ESXi would it be a better idea? For example for expanding storage capacity? i look for good solutions. Thanks in advance.

• Good, secure video chat program

  - by wag2639

  I'm looking for something similar to skype but basically just for me to video chat with my girlfriend. Skype has been kind of buggy lately with its recent iterations and doesn't seem to be progressing as much as when it was with its previous backers. Are there any good, secure video chat programs? Something that customizable and lets you choose framerate vs pixelation and is generally secure (I don't care if the NSA can tap it but no one else, especially over unencrypted wifi's). Open source is preferred but not required. Free or really really cheap is practically required. Also, since this is point to point, an i am a power user (and my gf as well), it can involve some manual setup to establish a point-to-point link. Any suggestions, Thanks.

• Redmine + Backlogs not working on Turnkey Linux (Ubuntu)

  - by Riddler

  I'm trying to get Redmine + Backlogs work, so for starters I took a virtual appliance with Redmine from Turnkey Linux (http://www.turnkeylinux.org/redmine) and installed Backlogs on top of it, following the installation instructions (http://www.redminebacklogs.net/en/installation/ - used method #2). It seems to have installed ok, but when I go to the "Backlogs" tab and attempt to create some stories, this is what I get - first shows some kind of error/warning icon, others continue to display "in progress" icon indefinitely (can't post a screenshot, unfortunately, but you can take a look at it here: http://www.redmine.org/attachments/5329/Backlogs.jpg). None of the stories get actually created - leaving this tab and returning back to it shows empty backlogs. So.. what am I doing wrong, and how to fix this?

• What is the best way to setup a public and private wireless access point on the same home network?

  - by Dougman

  For my home network (with internet provided from a cable modem) I would like to setup a secure wireless access point that I use for all of my personal connections (home PC, iPhone, Xbox, etc) and also another public access point that friends and folks in the neighborhood may connect to (for good karma). I want to ensure that my private traffic cannot be accessed from users of the public access point. I currently have one router that is running the Tomato firmware that I use with WPA security. What is the best way to accomplish this kind of setup securely (if it is possible in a home environment)?

• The mouse pointer in my Ubuntu VM has turned into a little hand with a document, and clicks are igno

  - by Daryl Spitzer

  The mouse pointer in my Ubuntu 8.04.3 LTS VM (running in VMware Fusion) has changed into a little hand holding a document. It doesn't show up in screen-shots. All mouse clicks (left or right) are ignored. But I can still type in the one Terminal window I have open. (And commands work fine.) I wonder if I'm in some kind of drag-and-drop mode. How do I get out of this? Update: Rebooting (from the command-line) worked. Ubuntu came up with the regular mouse-pointer.

• Too many connectons to 212.192.255.240

  - by Castor

  Recently, my Internet slowed down drastically. I downloaded a tool to see the TCP/IP connections from my Vista computer. I found out that a lot TCP/IP connections are being connected to 212.192.255.240 through SVCHost. It seems that it is trying to connect to different ports. I think that my computer is being infected with some kind of malware etc. But I am not sure how to get rid of it. I did a little bit of research on this IP but found nothing. Any suggestions are highly apprecitated.
