  • SQL Server v.Next (Denali) : Why you should start testing early

    - by AaronBertrand
    Denali is coming, whether you like it or not. You may not be an early adopter and you may not have plans on your current calendar, but at some point you will need to move your apps and databases to this release - or one very much like it. There are a lot of great new features you will be able to take advantage of, but not everything is a double rainbow. There are some changes that will break your spirit if you let them. What does it mean? I go over several breaking changes in my presentation that...(read more)

  • Providing SSH tunnling, what to think about when configuring Ubuntu Server

    - by bigbadonk420
    Recently I've considered, mostly as a pet project, to set up accounts for a closed group of users via SSH to my box with the purpose of SSH tunnling things like web traffic -- some of it for friends that live abroad and perhaps also to help some people bypass national censorship. There's some things I imagine that I need to do, such as: Disabling shell access by setting the shell to /bin/false or similar. Get some software that can track bandwidth usage on a per-user basis historically Make sure that each user can only use a certain amount of bandwidth. The reason I'm posting here to begin with is to look around and get some pointers regarding what kind of things I should read up on, as well as hearing if there are any software recommendations for doing what I'm trying to do. I already know a bit since I've actually gotten SSH tunnling up and running already, I just don't feel like letting it loose to other people without restrictions and some basic monitoring. I'm primarily trying to learn here, so if you think this is a Very Bad Idea (or if you have a better idea on how to do this) then by all means say so, but please include some information on how to do it :) (I'm also open to trying things like OpenVPN but it seems really hard to set up, also I've heard SSH more often works in locked down environments)

I have did: in /etc/modprobe.d/blacklist.conf: blacklist ipv6 blacklist ip6table_filter blacklist ip6_tables in /etc/sysctl.conf net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 net.ipv6.conf.lo.disable_ipv6 = 1 But ufw happily use v6 protocol, and in dmesg: ip6_tables: (C) 2000-2006 Netfilter Core Team . .

  • Wait Statistics in Microsoft SQL Server

    - by KKline
    When it comes to troubleshooting in relational databases, there's no better place to start than wait statistics. In a nutshell, a wait statistic is an internal counter that tells you how long the database spent waiting for a particular resource, activity, or process. Since wait statistics are categorized by type, one look will quickly tell the variety of problem that needs your attention, assuming you know meaning for Microsoft's lingo for each wait type....(read more)

  • The balance between client and server functionality

    - by Eugen Martynov
    I want to bring the discussion that started in our teams and get your opinion about it. Assume we have an user account which could have different credentials for authentication and associated email to recover. An user has possibility to do signup with an email or use his social profile to complete signup process. As an Rest API from the backend to client looks like: Create account Authorise Update user data Link social account Register email Verify email In addition our BE is distributed and divided between several services/servers/clusters. So different calls are related to different end points. In case of the social sign up some of steps should be skipped or simplified. For example, with Facebook signup we could already skip email registration and verification step (we ask email permission form user), linking the social account and pre-fill user displayed name. So we proposed to have another end point which will hide/combine different calls on BE and return whole process result to the clients. The pros for this approach: No more duplication of functionality between clients Speed up the networking and user experience The cons for this approach: Additional work for backend Probably most complex scenarios in future updates I would like to get your opinion or experience with this situation. Especially if you already experienced point #2 from against reasons.

  • Android - Multiplayer Game - Client / Server - Java etc

    - by user1405328
    I must write a multiplayer pong game for the school. Where are thousand of rooms and where two players can go in to a room and play together and collect points. I programmed the Pong game using Java (LibGDX). How can I do the Network part. I searched the web. And I came across Kryonet. Is there something better? What should I google. On the Internet there are a lot of those questions. And no good answers. I hope that this most questions can be answered. If someone has actual Open Source network game links, tutorials, books, network tutorial, etc. All this would help everyone. Thank you.

  • Mobile (Client) to Amazon S3 (Server) - Architecture

    - by wasabii
    let's start off with the problem statement: My iOS application has a login form. When the user logs in, a call is made to my API and access granted or denied. If access was granted, I want the user to be able to upload pictures to his account and/or manage them. As storage I've picked Amazon S3, and I figured it'd be a good idea to have one bucket called "myappphotos" for instance, which contains lots of folders. The folder names are hashes of a user's email and a secret key. So, every user has his own, unique folder in my Amazon S3 bucket. Since I've just recently started working with AWS, here's my question: What are the best practices for setting up a system like this? I want the user to be able to upload pictures directly to Amazon S3, but of course I cannot hard-code the access key. So I need my API to somehow talk to Amazon and request an access token of sorts - only for the particular folder that belongs to the user I'm making the request for. Can anyone help me out and/or guide me to some sources where a similar problem was addressed? Don't think I'm the first one and the amazon documentation is so extensive that I don't really know where to start looking. Thanks a lot!

  • How do I configure the number of worker threads used by SqlServer 2005 Agent

    - by Decker
    How can I increase the limit of worker threads from the default 10 for SQL Server 2005 SqlAgent? I have 9 jobs that run almost continuously and that leaves only one available thread for the rest of the scheduled jobs. Oftentimes, when no thread is available, I will see the jobs in "Waiting for worker thread" state. I'd like to increase the number to about 12 (which should do the trick for me). Any idea where this is set?

  • What is the differences between a Remote File Share Witness Quorum and a Disk Witness Quorum?

    - by arex1337
    Say you set up a Windows Server Failover Cluster consisting of two nodes, on Windows Server 2008 R2 Enterprise. Now when you want to configure quorum you can use either a remote shared folder, or a shared disk (unless your nodes are separated geographically). I'd love to know more about when to use a disk witness and when to use a file share witness. What are the differences? Does it matter at all?

  • Reg Query Issues

  • Is the master database backup crucial for restoring MS SQL server in the event where you have to res

    - by Imagineer
    I have been advise by Commvault partner support to turn off the backup of the master database as the backup failed due to the log file being lock. The following is the advise given: "The message is caused by Commvault’s inability to backup the master database’s transaction log. If this is happening intermittently its possible that something is locking the transaction log, preventing SQL iData agent from accessing the log. Typically the master database is just a template and is not used by any applications (applications that do require the use of an SQL database create their own) so there should be no harm in preventing it from being backed up You can do this by nominating NOT to back it up in the primary copy for the SQL data agent" The following is the error that I get. sqlxx SQL Server/ SQLxx N/A/ System DBs 19856* (CWE) Transaction Log N/A 01/08/2010 19:00:16 (01/08/2010 19:00:18 ) 01/08/2010 19:03:15 (01/08/2010 19:03:14 ) 1.44 MB 0:01:11 0.071 2 0 1 ITD014L2 Failure Reason: • ERROR CODE [30:325]: Error encountered during backup.

  • Why does my SQL Server use AWE memory? and why is this not visible in RAMMap?

    - by Marnix Klooster
    We have a Windows Server 2008 R2 (64-bit) 8GB server where, according to Sysinternals RAMMap, 2GB of memory is allocated using AWE. As far as I understood, this means that these pages stay in physical memory and are never pushed out. This causes other apps to be pushed out of physical memory. In RAMMap, on the Physical Pages tab, the Process column is empty for all of the AWE pages. We run SQL Server on that box, but (through SQL Server Management Studio, under Server Properties - Memory, under Server memory options) it says is configured not to use AWE. However, when stopping SQL Server, the AWE pages are suddenly gone. So it really is the culprit. So I have three questions: Why does RAMMap not know/show that a SQL Server process is responsible for that AWE memory? Why does SQL Server Management Studio say that AWE memory is not used? How do we make configure SQL Server to really not use AWE memory?

  • Cannot establish XMPP server-to-server connection to gmail

    - by v_2e
    My jabber-server fails to connect to gmail.com giving the error: outgoing s2s stream myserver.com.ua-bot.talk.google.com closed: undefined-condition (myserver.com.ua is a Google Apps Domain with Talk service enabled.) I am using the Prosody XMPP server. It works just fine with other jabber-servers I tested so far (e.g. jabber.ru). However, when some of my clients tries to add a gmail contact to his contact-list, the subscription request lasts forever, and the Prosody gives the following sequence of messages in its log: Oct 21 22:57:16 s2sout95897f8 info Beginning new connection attempt to gmail.com ([173.194.70.125]:5269) Oct 21 22:57:16 s2sout95897f8 info sent dialback key on outgoing s2s stream Oct 21 22:57:16 s2sout95897f8 info Session closed by remote with error: undefined-condition (myserver.com.ua is a Google Apps Domain with Talk service enabled.)

Oct 21 22:57:16 s2sout95897f8 info sending error replies for 2 queued stanzas because of failed outgoing connection to gmail.com Here for the domain name of my server I use myserver.com.ua I found a similar problem described in this thread, but there is no detailed description of the solution there. As for the Google services, I did have a google account where I added the domain name under question to the Webmasters tools page. However, I deleted my account long ago, so now it is unclear, how any of the Google services can relate to my domain name. So my question is: What is the real cause of this problem (my jabber-server configuration or imaginary Google account or something else) and how can I make my Prosody server connect to gmail.com jabber service?

  • Chrooted pygopherd fails to find new directories and files

    - by Carsten R
    I tried to setup a Pygopherd on my server. The default setup works fine, but when I try to change the gophermap to point to a new directory with a new file, I get an error message in my gopher client: --- [1] '/path/to/gopher/newdir' does not exist (no handler found) First I thought this is caused by the chroot in which pygopherd runs as default. But when I disable the chroot, the same error comes up. Did anyone successfully set up pygopherd or knows about a better gopher server?

  • how to portforward port 7300 from server A to server B

    - by Patrick van Hout
    hi, We are using Stunnel. But want to replace it is with an iptables entry if possible. 192.168.123.122:7300 need to be forwarded to 192.168.123.188:7300. So in iptables I set these two entries: [root@dev ~]# iptables -t nat -A PREROUTING -p tcp --dport 7300 -j DNAT --to-destination 192.168.123.188:7300 [root@dev ~]# iptables -A FORWARD -m state -p tcp -d 192.168.123.188 --dport 7300 --state NEW,ESTABLISHED,RELATED -j ACCEPT But it isn't working. I did check that /proc/sys/net/ipv4/conf/eth0/forwarding has the value "1" inside. Any tips or hints? thanks, Patrick
