• VS2008 is very slow on a specific large C++ solution

  - by VioletRose

  I have a solution with 21 C++ projects and 1 VB.NET project. The IDE responds very slowly when I simply move the carret in a file or try to open the menu. The process seems to take 50% of CPU for each movement. It only happens with this solution and only on my machine. The solution has total of 2380 source and header files, of which 1280 are header files. I tried to remove all connection to the source control (Perforce) but it didn't help. Also, I have Visual Assist installed but even after removing it (uninstall), the same behavior continued. Any idea?

• Performance analytics via DBMS "plugins", or other solution

  - by Polynomial

  I'm working on a systems monitoring product that currently focuses on performance at the system level. We're expanding out to monitoring database systems. Right now we can fetch simple performance information from a selection of DBMS, like connection count, disk IO rates, lock wait times, etc. However, we'd really like a way to measure the execution time of every query going into a DBMS, without requiring the client to implement monitoring in their application code. Some potential solutions might be: Some sort of proxy that sits between client and server. SSL might be an issue here, plus it requires us to reverse engineer and implement the network protocol for each DBMS. Plugin for each DBMS system that automatically records performance information when a query comes in. Other problems include "anonymising" the SQL, i.e. taking something like SELECT * FROM products WHERE price > 20 AND name LIKE "%disk%" and producing SELECT * FROM products WHERE price > ? AND name LIKE "%?%", though this shouldn't be too difficult with some clever parsing and regex. We're mainly focusing on: MySQL MSSQL Oracle Redis mongodb memcached Are there any plugin-style mechanisms we can utilise for any of these? Or is there a simpler solution?

• Finding a backup and synchronization solution

  - by Andrea Zilio

  I'm having difficulties to find a backup and synchronization solution with the following characteristics: Cross-platform: Windows, Linux, Mac Offsite backup (so Internet Backup) Data deduplication Transfer only new/modified bits of modified files Secure: Data encrypted before leaving computer Maintain multiple versions of files (even deleted files) Folder synchronization integrated with backup and across multiple computers connected to the internet (not necessarily in the same LAN) I think that the Folder Sync feature needs a better explanation. The use case is this: you have a desktop pc and a laptop. The desktop pc contains a folder with some files and this folder is part of the backup (so it was selected to be backed up). The laptop does not contain that folder or that files at all. Then you're abroad with your laptop and you need that folder. So you want to be able to open the backup program, select that folder from the backup and download it in your laptop mantaining it synchronized with the backed up version. When you then come back home and switch on your desktop pc you want the folder we're talking about to be updated in the desktop PC. Does anyone knows any service with all these features? I've only found SpiderOak to support all the features I've mentioned but I'm not completely satisfied by the time taken to complete a backup. Sometimes it seems to hang for minutes with no reasons at all and folder synchronization occurs only after all files are backed up (instead folder sync should have a separated queue independent from other backup operations and synchronization should occurs frequently... for example every 5 minutes or less, independently from the frequency of normal backup operations)

• SharePoint solution package not deploying to all front-ends

  - by Alex

  I have a WSP that contains a web part. It's being built using WSPBuilder. Most of the time, the WSP deploys perfectly. However, in two of our test environments (and sadly, in production, too) the WSP doesn't deploy properly to all the web front ends. The assemblies make it into the GAC, and the .webpart files get provisioned. The problem is that a tool part that the web part relies on for configuration simply fails to appear. I've determined that every time this has happened, it has been isolated to a single web front end. I've been able to resolve the issue by doing an stsadm -o deploysolution to re-deploy the solution, and in one instance it was resolved by the end user deactivating/reactivating the feature. Unfortunately, though, this has made it impossible to determine if the control isn't being deployed properly, or if it's some other issue. Any thoughts on this? Could it be a problem with the WSP, or is it likely to be environmental?

• Redundant Microsoft server solution for small company

  - by MadBoy

  I'm planning to change one server Microsoft SBS 2003 with SharePoint, Exchange and SQL database into something that will provide me with some redundancy and won't be single point of failure. I was thinking to buy 2x exactly the same physical servers and put 2 virtualized servers on HyperV or VMWare on each. Then i would put SharePoint, Exchange and SQL on that 1 physical server (shared onto 2x VM's). I would like 2nd physical server to be exact duplicate of the first one so that when 1st server goes down (for reboot or hw failure), 2nd takes care of everything so that users don't even see anything changed (in terms all their emails, sharepoint stuff is available). My questions are: Will I have to pay for licenses for both servers even thou only one instance of SharePoint, Exchange, SQL will be used at same time? What are proposed solutions to do that? Any additional hardware I would need, any complicated software configuration to be expected to configure such redundancy so that when one physical server goes down 2nd one is taking care of rest? What problems should I expect? This solution is for 60 people. Later on it may or may expand.

• Home media storage solution

  - by Dan

  I record lots of personal HD film footage and am looking for a cheap way to store all of this. I take ~120 GB of footage each month, so something expandable would be nice... something that might be able to hold 6+ SATA drives. There is a low load requirement, as there is never more than a user or two... but it should be able to keep up with streaming 2 simultanious HD videos. I don't really want to spend more than $200-$300 on top of the $900 I am thinking of spending for 6X2GB SATA drives@ $150 apiece, but I am willing to pay extra for a quality solution. Should I get a cheap NAS server? a cheap multi-drive external enclosure? should I just get some used systems off craigslist? If it is an independent system I'll probably just throw ubuntu on it since I can maintain that well. Its easy to do a software raid from ubuntu too, if I choose to go that way. Thanks

• Fully FOSS EMail solution

  - by Ravi

  I am looking at various FOSS options to build a robust EMail solution for a government funded university. Commercial options are to be chosen only in the worst case scenario. Here are the requirements: Approx 1000-1500 users - Postfix or Exim? (Sendmail is out;-)) Mailing lists for different groups/Need web based archive - Mailman? Sympa? Centralised identity store - OpenLDAP? Fedora 389DS? Secure IMAP only - no POP3 required - Courier? Dovecot? Cyrus?? Anti Spam - SpamAssasin? what else? Calendaring - ?? webmail - good to have, not mandatory - needs to be very secure...so squirrelmail is out;-)? Other questions: What mailbox storage format to use? where to store? database/file system? Simple and effective HA options? Is there a web proxy equivalent to squid in the mail server world? software load balancers?CARP? Monitoring and alert? Backup? The govt wants to stimulate the local economy by buying hardware locally from whitebox vendors. Also local consultants and university students will do the integration. We looked at out-of-the-box integrated solutions like Axigen, Zimbra and GMail but each was ruled out in favour of a DIY approach in the hopes of full control over the data and avoiding vendor lockin - which i though was a smart thing to do. I wish more provincial governments in the developing world think of these sort of initiatives As for OS - Debian, FreeBSD would be first preference. Commercial OS's need not apply. CentOS as second tier option...

• Some free cloud solution to enhance your business

  - by Saif Bechan

  I am co-owner of a small internet business. I am in charge of IT, and I try to get things done as low cost as possible. When investing in servers, resources and overall business costs your project can soon turn into a financial disaster. Cloud solutions can help you in solving some financial problems, they can help you in scalability problems, and overall performance problems of your server or web application. Recently I moved the whole internal/external communication(email,calendar,documents) of my business to the cloud. I did this by using the free version of Google Apps. This works great and is a big advantage on multiple levels. I do not have to fight spam anymore on my system, and there are less resources used on my system. Also switching servers will go a lot easier. Questions Can you name some cloud solution that you have used, or some you just recommend. They can fairy form financial benefits, organizational benefits, performance benefits. It doesn't matter as soon as it helps you spread the load of your business.

• One Active Directory, Multiple Remote Desktop Services (Server 2012 solution)

  - by Trinitrotoluene

  What I am trying to do is quite complex, so I figured I'd throw it out to a wider audience to see if anyone can find a flaw. What I am trying to do (as an MSP/VAR) is design a solution that will give multiple companies a session based remote desktop (companies that need to be kept completely seperate), using only a handful of servers. This is how I imagine it at the moment: CORE SERVER - Server 2012 Datacentre (All below are HyperV servers) Server1: Cloud-DC01 (Active Directory Domain Services for mycloud.local) Server2: Cloud-EX01 (Exchange Server 2010 running multi tenant mode) Server3: Cloud-SG01 (Remote Desktop Gateway) CORE SERVER 2 - Server 2012 Datacentre (All below are HyperV servers) Server1: Cloud-DC02 (Active Directory Domain Services for mycloud.local) Server2: Cloud-TS01 (Remote Desktop Session Host for Company A) Server3: Cloud-TS02 (Remote Desktop Session Host for Company B) Server4: Cloud-TS03 (Remote Desktop Session Host for Company C) What I thought about doing was setting up each Organisation in their own OU (perhaps creating their OU structure based on the Excahnge 2010 tenant OU structure so the accounts are linked). Each company would get a Remote Desktop Session Host server that would also serve as a file server. This server would be seperated from the rest on its own range. The server Cloud-SG01 would have access to all these networks and route the traffic to the appropriate network when a client connects and authenticated so they are pushed onto the correct server (Based on session collections in 2012). I won't lie this is something I have come up with quite quickly so there may well be something gapingly obvious that I am missing. Any feedback would be appreciated.

• Netgear FVS336G: appropriate solution for today's small businesses?

  - by bwerks

  Hey all, I've been looking into a routers to facilitate a vpn solution for a small business. While the Netgear FVS336G looks good on paper, it appears to have some fairly crippling setbacks that drag down what appears to be some great hardware. First off, the unit has been around for a couple years now, perhaps before 64-bit operating systems were as common as they are now, and complaints are everywhere that claim that SSL or IPsec (or both) VPN connections will not work with 64-bit operating systems. However, most of these claims mention only Vista, which makes me think that these problems could have potentially been solved since then. Unfortunately though, Netgear's support forums seem to be incredibly private, and policed by some troll named jmizuguchi who just closes down public posts in order to marshal them into the private ones. Danger, will robinson. Apparently their firmware upgrade process is a nightmare too, but that's beside the point. My question is this: has anyone configured one a Netgear FVS336G to operate in a server 2008 (or R2)/windows 7 64-bit network? If so, is it possible to use the microsoft vpn client or are third party clients still required? If this thing has just failed the test of time, is there a feature-comparable unit that I've missed, at anywhere near the same price range? Thanks!

• Looking for a host based network monitor solution

  - by Ole Martin Handeland

  Hi all! Problem So, my hosting company has a network usage graph for my dedicated server. It seems that one day earlier this month, my network usage suddenly spiked with several hundred megabytes transferred (usually it's in the tens, not hundreds). It was probably me, but i just can't be sure who or what it was. Question So my question is; does anyone know of any host based solution for monitoring network usage that would tell me the client's IP-address, the port/service he/she used? What I don't want I'm just guessing that someone will suggest i use nagios, munin, zabbix, cacti, mrtg - I've also looked at those, but a graph over network usage will not give me the answers I'm looking for. :-) Almost there I've already looked at a lot of monitoring solutions, and I've tried [ntop][http://www.ntop.org/], [darkstat][http://unix4lyfe.org/darkstat/] and others. Darkstat just didn't give me the answers. Although it listed a lot of statistics, and i could list the clients - it doesn't show me the network usage for a particular period. Ntop is by far the best I've seen so far - but i think it mostly shows current network usage, not the historical part. I could run apt-get upgrade and download a whole bunch of software, but not see it in the log afterwards.

• File Sync Solution for Batch Processing (ETL)

  - by KenFar

  I'm looking for a slightly different kind of sync utility - not one designed to keep two directories identical, but rather one intended to keep files flowing from one host to another. The context is a data warehouse that currently has a custom-developed solution that moves 10,000 files a day, some of which are 1+ gbytes gzipped files, between linux servers via ssh. Files are produced by the extract process, then moved to the transform server where a transform daemon is waiting to pick them up. The same process happens between transform & load. Once the files are moved they are typically archived on the source for a week, and the downstream process likewise moves them to temp then archive as it consumes them. So, my requirements & desires: It is never used to refresh updated files - only used to deliver new files. Because it's delivering files to downstream processes - it needs to rename the file once done so that a partial file doesn't get picked up. In order to simplify recovery, it should keep a copy of the source files - but rename them or move them to another directory. If the transfer fails (network down, file system full, permissions, file locked, etc), then it should retry periodically - and never fail in a non-recoverable way, or a way that sends the file twice or never sends the file. Should be able to copy files to 2+ destinations. Should have a consolidated log so that it's easy to find problems Should have an optional checksum feature Any recommendations? Can Unison do this well?

• Cheap Solution for Routing a Toll Free Number to a Standard POTS Number

  - by VxJasonxV

  I do some technical work for an Internet Radio Show/Podcast, and need to fix something that has been broken for a while. The hosts have a Skype-In number to take listener calls, and for convenience sake, I bought and paid for a toll free number for a period of time. I used to use Asterlink for routing calls, but they folded and sent my number to OneBox, but they're ridiculously expensive by comparison. I'm looking for a cheap solution for this one simple task. Forward toll free calls to a skype-in number. The definition of cheap is as cheap or cheaper than Asterlink was. I paid something like $2 a month, and then the termination/call rate, which was a fraction of a sent for termination, and only whole cents after some serious time on the call. A $20 preload lasted me months at a time. I don't want to be upsold too, I want a simple web based management screen (CDR/stats are fun!), and obviously, it needs to be reliable. What vendors out there are you a fan of that solves this need?

• I need a reverse proxy solution for SSH

  - by Bond

  Hi here is a situation I have a server in a corporate data center for a project. I have an SSH access to this machine at port 22.There are some virtual machines running on this server and then at the back of every thing many other Operating systems are working. Now Since I am behind the data centers firewall my supervisor asked me if I can do some thing by which I can give many people on Internet access to these virtual machines directly. I know if I were allowed to get traffic on port other than 22 then I can do a port forwarding. But since I am not allowed this so what can be a solution in this case. The people who would like to connect might be complete idiots.Who may be happy just by opening putty at their machines or may be even filezilla.I have configured an Apache Reverse Proxy for redirecting the Internet traffic to the virtual machines on these hosts.But I am not clear as for SSH what can I do.So is there some thing equivalent to an Apache Reverse Proxy which can do similar work for SSH in this situation. I do not have firewall in my hands or any port other than 22 open and in fact even if I request they wont allow to open.2 times SSH is not some thing that my supervisor wants.

• Best solution top keep data secure

  - by mrwooster

  What is the simplest and most elegant way of storing a small amount of data in a reasonably secure way? I am not looking for ridiculous levels of advanced encryption (AES-256 is more than enough) and I am only looking to encrypt a small number of files. The files I wish to encrypt are mostly comprised of password lists and SSH keys for servers. Unfortunately it is impossible to keep track of ever changing passwords for my servers (and SSH keys) and so need to keep a list of the passwords. Obviously this list needs to be secure, and also portable (I work from multiple locations). At the moment, I use a 10MB encrypted disk image on my mac (std .dmg AES-256) and just mount it whenever I need access to the data. To my knowledge this is very secure and I am very happy using it. However, the data is not very portable. I would like to be able to access my data from other machines (especially ones running linux), and I am aware that there are quite a few issues trying to mount an encrypted .dmg on linux. An alternative I have considered is to create a tar archive containing the files and use gpg --symmetric to encrypt it, but this is not a very elegant solution as it requires gpg to be installed on every system. So, what over solutions exist, and which ones would you consider to be the most elegant? Ty

• solution for an offline server

  - by dashmug

  I'm trying to setup a development server at work that will ideally be able to test drive a couple of projects in PHP, Rails, or Django (not always running at the same time). I develop the apps locally on a Mac and then I'll put the projects up on this server for testing with my actual users (non-techies) before deploying to a production server. My problem is that we have a very poor internet connection (almost negligible) at work and doing the usual apt-get/yum/ports (make, clean, install) processes for setting up servers always get their packages from online repositories somewhere. I know I could probably download the source and then compile them myself but that's going to be too much of a hassle for me. I'm thinking about two solutions: Plan A: Run a server VM on my Mac and then use this VM as the source repository for the offline server. I've read about Ubuntu's apt-proxy and it seems to be good enough though I haven't tried it yet. I'm not sure if this is possible but can I simply do apt-get install nginx --downloadonly so that the package and its dependencies will be downloaded into my VM and my server can use the VM as the source repo for apt-get? Plan B: Run a server VM on my Mac (which I can setup/update easily when I'm home) and then clone the VM to the offline development server. Maybe I should simply make the server a VM host so I can simply copy the VM over. I think this is okay for the first-time setup but subsequent updates will take too long (cloning the VM image). If I was working on Windows, I imagine it'd be easier because most services have an installer file that I can download and then run at the server. If you could suggest another way, it would be much appreciated. Update: From Michael Hampton's answer, I found a possible solution which is apt-cacher. I also found this page on Ubuntu's website. I wonder if there is a better tool than this one.

• Force "Internet Explorer 8" browser mode in intranet

  - by Dennis Cheung

  There are "Internet Explorer 8", "Internet Explorer 8 Compatibility Mode", and IE7 mode in IE8. However, the default setting in IE make all intranet website use "IE8 Compatibility Mode" even I have setted doctype, the meta tag, http header as suggested to force it into IE8 mode. I have <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd" and <meta http-equiv="X-UA-Compatible" content="IE=8" But it still goes into "IE8 Compatibility Mode", without any changes in IE setting. How to force it into pure "IE8" mode, without change any browser's setting? PS. I am not talking "document mode" here.

• Prevent Windows Explorer from interfering with Directory operations.

  - by Bruno Martinez

  Sometimes, no "foo" directory is left after running this code: string folder = Path.Combine(Path.GetTempPath(), "foo"); if (!Directory.Exists(folder)) Directory.CreateDirectory(folder); Process.Start(@"c:\windows\explorer.exe", folder); Thread.Sleep(TimeSpan.FromSeconds(5)); Directory.Delete(folder, false); Directory.CreateDirectory(folder); It seems Windows Explorer keeps a reference to the folder, so the last CreateDirectory has nothing to do, but then the original folder is deleted. How can I fix the code?

• Group SQL tables in SQL Server Management Studio object explorer

  - by MainMa

  I have a table which has approximately sixty tables, and other tables are added constantly. Each table is a part of a schema. A such quantity of tables makes it difficult to use Microsoft SQL Server Management Studio 2008. For example, I must scroll up in object explorer to access database related functions, or scroll down each time I need to access Views or Security features. Is it possible to group several tables to be able to expand or collapse them in Object Explorer? Maybe a folder may be displayed for each schema, letting collapse the folders I don't need to use?

• recommendations for efficient offsite remote backup solution of vm's

  - by senorsmile

  I am looking for recommendations for backing up my current 6 vm's(and soon to grow to up to 20). Currently I am running a two node proxmox cluster(which is a debian base using kvm for virtualization with a custom web front end to administer). I have two nearly identical boxes with amd phenom II x4's and asus motherboards. Each has 4 500 GB sata2 hdd's, 1 for the os and other data for the proxmox install, and 3 using mdadm+drbd+lvm to share the 1.5 TB's of storage between the two machines. I mount lvm images to kvm for all of the virtual machines. I currently have the ability to do live transfer from one machine to the other, typically within seconds(it takes about 2 minutes on the largest vm running win2008 with m$ sql server). I am using proxmox's built-in vzdump utility to take snapshots of the vm's and store those on an external harddrive on the network. I then have jungledisk service (using rackspace) to sync the vzdump folder for remote offsite backup. This is all fine and dandy, but it's not very scalable. For one, the backups themselves can take up to a few hours every night. With jungledisk's block level incremental transfers, the sync only transfers a small portion of the data offsite, but that still takes at least a half an hour. The much better solution would of course be something that allows me to instantly take the difference of two time points (say what was written from 6am to 7am), zip it, then send that difference file to the backup server which would instantly transfer to the remote storage on rackspace. I have looked a little into zfs and it's ability to do send/receive. That coupled with a pipe of the data in bzip or something would seem perfect. However, it seems that implementing a nexenta server with zfs would essentially require at least one or two more dedicated storage servers to serve iSCSI block volumes (via zvol's???) to the proxmox servers. I would prefer to keep the setup as minimal as possible (i.e. NOT having separate storage servers) if at all possible. I have also briefly read about zumastor. It looks like it could also do what I want, but it appears to have halted development in 2008. So, zfs, zumastor or other?
