  • SQL 2008 Replication over Internet

    - by Akash Kava
    We have decided to put our servers in data centers on east and west coast of US, to keep high level redundancy. After evaluating number of replication options, apart from VPN there is no other way to do replication for SQL Server. We are investigating VPN but I have following questions. Our Large DB consists of media information (pictures/movies/audio/pdf) etc, so we are not very concerned about security because they are not financial sensitive data. SQL 2005 supports or can be configured to support replication over internet? If Yes then should we downgrade to 2005? If SQL 2008 Publisher is configured for Web Sync, can we write an automatic program (C# Windows Service) to act as pull subscriber and run on the subscriber server and replicate subscriber database? Or are there any API available in SQL where we can write our own program to do replication in very generic way? (In a nut shell, can we write our own C# Windows Service based Subscriber program?)

  • Where do I define a group policy that will set a users desktop background color to green the first time they log in?

    - by Tyler
    Servers: W2k8 R2 x64 Desktops: Win7 Pro x64 Our current group policy uses a custom ADM file to define certain properties of the desktop (Background Image (centered), Background Color is green (00 74 00)). This policy works for us, but the down-side is that policies defined in our custom ADM are only applied after a GPUpdate /Force is applied. We would like these desktop theme settings to be applied the first time the user logs onto the computer. I've been working on a new policy that forces the computer to wait for the network when the user logs on to handle folder redirection. The reason for writing the new policy was to resolve the issue that a user needs to run GPupdate /Force the first time they log in, so it doesn't make sense for me to implement the new policy if there is still something that requires GPUpdate /Force to get the user in the state that we want them. I've moved the setting for background image out into Admin Templates- Desktop- Desktop- "Desktop Wallpaper" so this is now being set properly when the user first logs in. Now I'm left with a black background until I force a group policy update. I have tried to play around with setting a default "Theme" and had limited success; this was not reliable enough to call a solution. I suppose I could set the background color with a script? Any thoughts? It feels like I'm missing something obvious, or that this should be much easier than it is.

  • Try exchange in real domain

    - by AndreaCi
    We (as a company) 'd like to try exchange server to replace our mail server. I downloaded the demo version from Microsoft website, but during the installation it wants administrator access to domain to edit the Active Directory database structure. The test will last for (at least) a month to see if it will bring real advantages to our management systems. Here is my question: Is it "dangerous"? If I uninstall the exchange server everything will be reverted to previous state? I'm kind of "scared" about the changes he may apply to our domain controllers.

  • Apache rewrite rules and special characters

    - by Massimo
    I have a server where some files have an actual %20 in their name (they are generated by an automated tool which handles spaces this way, and I can't do anything about this); this is not a space: it's "%" followed by "2" followed by "0". On this server, there is an Apache web server, and there are some web pages which links to those files, using their name in URLs like http://servername/file%20with%20a%20name%20like%20this.html; those pages are also generated by the same tool, so I (again!) can't do anything about that. A full search-and-replace on all files, pages and URLs is out of question here. The problem: when Apache gets called with an URL like the one above, it (correctly) translates the "%20"s into spaces, and then of course it can't find the files, because they don't have actuale spaces in their names. How can I solve this? I discovered than by using an URL like http://servername/file%2520name.html it works nicely, because then Apache translates "%25" into a "%" sign, and thus the correct filename gets built. I tried using an Apache rewrite rule, and I can succesfully replace spaces with hypens with a syntax like this: RewriteRule (.*)\ (.*) $1-$2 The problem: when I try to replace them with a "%2520" sequence, this just doesn't happen. If I use RewriteRule (.*)\ (.*) $1%2520$2 then the resulting URL is http://servername/file520name.html; I've tried "%25" too, but then I only get a "5"; it just looks like the initial "%2" gets somewhat discarded. The questions: How can I build such a regexp to replace spaces with "%2520"? Is this the only way I can deal with this issue (other than a full search-and-replace which, as I said, can't be done), or do you have any better idea?

  • Backup hardware and strategy on distributed Windows Server 2008 network

    - by CesarGon
    This question is a follow up to this. We have a Windows Server 2008 R2 domain over a network that spans two different buildings, linked by a 100-Mbps point-to-point line. Over 60 users work in the organisation. We are planning to use DFS folders and DFS replication for file serving across the organisation. The estimated data volume is over 2 TB, and will grow at approximately 20% annually. The idea is to set up a DFS file server in each building and use DFS so that all the contents stay replicated over the 100-Mbps link. We are now considering backup hardware and strategies. We are Dell customers and, after browsing the online Dell catalogue, I can see a number of backup hardware options. My main doubts are the following: Would you go for a tape library, disk backup, or are there other options worth considering? Would you perform batch backups (i.e. nightly) or would you use continuous backup (i.e. while users are working)? Would you use a dedicated backup server to which the tape library (or any other backup device) is attached, or is there any other alternative way of doing things? My experience with backup hardware and overall setup is limited, so I appreciate any good piece of advice that you may have. Thanks.

  • Built local glibc, broke system, how do I ssh without parsing the .bashrc?

    - by Mikhail
    The cluster I am on had really old build tools and I needed to use CUDA5. I'm a pretty clever dude and I planned on building the necissary tools. So, I built a local copy of gcc, bintools, and glibc. Everything a CUDA5 could want. All builds finished without error. and I tested gcc and bintools. Everything was wonderful and I built and ran a few of the programs. I set up the LD_LIBRARY_PATHs in the .bashrc and logged back in, expecting a productive night ahead. To my horror I realized that everything is dynamically linked. Now I can't do simple commands like ls [ex@uid377 ~]$ ls ls: error while loading shared libraries: __vdso_time: invalid mode for dlopen(): Invalid argument and I can't do commands to fix the problem like rm or vim! Is there a way for me to ssh but also to ignore .bashrc file? Any suggestions are much appreciated. This machine is obviously under maintained and I don't know when I could have administrator support.

  • Puppet Agent still able to connect to Master after certificate revocation

    - by chris
    In summary: Client connects for the first time and requests cert; on the Master, puppetca -s client is executed; Client gets the cert and completes the run successfully. Fine. But now: on the Master, puppetca -c client is executed and client's cert is not in the cert list anymore; Client connects again and can perform the run as usual; Restarting puppetmasterd doesn't solve the issue. How can I prevent client to connect once its cert has been revoked? Thanks in advance

  • ssh over a tunnel in order to configure auto login

    - by Vihaan Verma
    I m trying to copy the id_rsa.pub key to the server. The server in my case also has a virutal machine called dev which runs on the host machine. I copied the id_rsa.pub key to the host for auto log in using this command. ssh-copy-id -i ~/.ssh/id_rsa.pub vickey@host which worked fine and I can auto log in to host. I also wanted to auto log in to the dev machine. I know I can just copy the contents of authorized_keys from the host machine to the dev machine but I m looking for a command line of doing things. Creating a tunnel seemed like the solution ssh vickey@host -L 2000:dev:22 -N now when I tried ssh-copy-id -i ~/.ssh/id_rsa.pub vickey@localhost -P 2000 the password that worked here was of my local machine , I expected it to ask me password of my dev machine. The above command adds the pub key to the local machine and not to the dev machine. However this commands asks me for the dev password and copies the files. scp -P 2000 vickey@localhost:/home/vickey/trash/vim . vickey@localhost's password: vim 100% 111 0.1KB/s 00:00 How do I do the same with ssh-copy-id ?

  • What is a Linux device name for RAID of sas drives?

    - by flashnik
    I have a RAID1 using Promise FastTrack TX2650 consisting of 2 SAS drives. What is a Linux device name for them? Like sda is for first sata drive. I have Windows server so I can't look it directly but need this information for smartctl usage. UPDATE. I found how to access RAID: smartctl -d scsi sdb (because I also have a SATA drive). But in this case I just get an information about just raid controller though I wantto get information about drives itself. Is it possible? Promises's control panel provides information only about their healthy status (boolean) and I want more. Mostly now I need information about temperature.

  • Redirect URL within Apache VirtualHost?

    - by DisgruntledGoat
    I have a dedicated server with Apache, on which I've set up some VirtualHosts. I've set up one to handle the www domain as well as the non-www domain. My VH .conf file for the www: <VirtualHost *> DocumentRoot /var/www/site ServerName www.example.com <Directory "/var/www/site"> allow from all </Directory> </VirtualHost> With this .htaccess: RewriteEngine on RewriteBase / RewriteCond %{HTTP_HOST} ^www.example.com [NC] RewriteRule ^(.*)$ http://example.com/$1 [L,R=301] Is there a simple way to redirect the www to the non-www version? Currently I'm sending both versions to the same DocumentRoot and using .htaccess but I'm sure I must be able to do it in the VirtualHost file.

  • Will disk cloning resolve bad stripes on RAID?

    - by user13323
    Hi. We have a logical RAID1 drive in bad stripes state, which kept that status even after replacement and rebuilding of both drives, and gives errors in Windows logs about failure of writing to disk. IBM support suggests erasing and re-creating the RAID, then re-installing the Windows. The resulting down-time unacceptible for us, so we want to clone the RAID (via Acronis True Image), erase and re-create the RAID, then dump the cloned data back. Following IBM logic where RAID erasing and re-creation resets the whole RAID meta-data, this should clear the bad-stripes status, and start from a blank page. Question is if such strategy is possible, and will produce the desired effect? Any idea is appreciated - thanks in advance!

  • Recommendation using Client side performance monitoring (boomerang/jiffy/episodes)

    - by Yasei No Umi
    There are a few Client-side JavaScript libraries that check web-site performance on the client side: Jiffy (http://code.google.com/p/jiffy-web/) Episodes (http://stevesouders.com/episodes/) by Steve Sounders Boomerang (http://yahoo.github.com/boomerang/doc/) by Yahoo! Have you used any of them or a similar too? What did you use for the server-side? for reporting? Is this a recommended approach? If not, how should I monitor my web-site performance from the end-user's view?

  • EFI Partition Types

    - by Will
    Another employee was working with a mounted VHD and was using diskpart on it and I'm not sure if he messed something up or not. I think it's fine but I wanted to double check. We have a Windows 2008 x64 machine that boots with EFI because of the large disks in the system. What should the different labels be within Disk Manager for this system? Here is what is currently set: 200 MB Partition - EFI System Partition C Partition - Boot, Page File, Crash Dump There should not be an active partition under EFI, correct? Also, is there supposed to be a "System" label in addition to "EFI System Partition"?

Any suggestions would be appreciated.

  • Reduce the I/O priority of Windows Backup (Windows Server 2008 R2)

    - by HelloSam
    I have a PostgreSQL running on Windows Server 2008 R2 x64 box. And I have scheduled a backup everyday from the RAID 1 DB disk to a dedicated standalone disk. They are SAS 15k on Dell PERC 6i. I am using the built-in Windows Server Backup for purpose. The problem is, whenever the backup process is kicked in, the database performance is hogged. I would say almost a 10x of performance reduction. From the resource monitor, the disk queue is in the double digit range when backing up, and less than 1 during the day. The disk activity is like ~30-50MB/s during backup, so I guess the hardware is acting normally, though wbengine.exe takes up most of the portions. I think reduce the IO priority of the backup process would be an answer, but I couldn't find a way to. Tuning process CPU priority does not seems to help.

  • what causes drops in apache throughput?

    - by Robbie Mckennie
    i was poking around in the windows task manager, and i found this cool network throughput graphing thing. so i wanted to see it max out, so i started downloading a 1.8gb image (from the localhost to a remote system). but, much to my surprise, it looked like this: i count 16 dips, so i divided the 1.8gb into 16 and i got 115mb. then i looked up the mtu of ip, and i knew the mtu of ethernet from my reading, both far smaller than 115mb. and since tcp is connection orientated, it doesn't have an mtu.

  • IIS Logs not getting created

    - by Chris
    Hi I have a site running on IIS 6. I have turned on logging on the website tab of IIS and specified a directory for it to write to. Set it to an hourly schedule. However no logs are ever created. Have reset iis. checked disk space and permissions on the directory it is writing to but no logs are ever created. I can see this did work once, as there are logs created in the system32/logfiles directory from about a year ago. Even if I specify that directory nothing new gets created This is on a hosted service What else can I check? Is there any place that errors would be written to that might give me a clue as to what is going on? Have tried event viewer but nothing untoward in there Would appreciate any pointers on this

  • How to move SharePoint authentication from AD to LDAP without breaking user profiles?

    - by Dan
    We have a bunch of users in a local Active Directory OU that access the SharePoint portal. We've just added LDAP authentication and pointed it at the organisation's global LDAP server, so out AD accounts are now redundant. Is there a way to re-map the authentication for a SharePoint (MOSS 2007) user/profile. That is, can we manually change a lot of users so that they log in with their LDAP credentials and get the same SharePoint MySite, groups, etc. as when they were authenticating via AD?

  • Apache2 Manage Server default

    I'm trying to setup two domains correctly. I have some issues I hope you can help me. Site one's conf: <VirtualHost myipaddress:80> ServerName www.domain1.com ServerAdmin [email protected] DocumentRoot /home/domain1/public_html </VirtualHost> My other domain conf is: <VirtualHost myipaddress:80> ServerName www.domain2.com ServerAlias *.domain2.com domain2.com ServerAdmin [email protected] DocumentRoot /home/domain2/public_html </VirtualHost> The default site is disabled. The problem is that when accessing "domain2.com" from my browser, it always redirects to "www.domain1.com". It only works when I excplicitly access "www.domain2.com". I have also other domains like "domain1.net", "domain1.info" pointing to my server but at this moment are not configured either setup on Apache yet I can access from browser and always accessing to "www.domain1.com". By the way is there any possible configuration over Apache to handle IP only, I mean if I type "http://myipaddress/" I get the "www.domain1.com"... Arrgh.
