  • AWS document on number of databases allowed on an Amazon RDS instance

    - by user35042
    At the Amazon RDS FAQ there is the question "What is a database instance (DB Instance)?". The entire answer (as of mid-June 2012) is: You can think of a DB Instance as a database environment in the cloud with the compute and storage resources you specify. You can create and delete DB Instances, define/refine infrastructure attributes of your DB Instance(s), and control access and security via the AWS Management Console, Amazon RDS APIs, and Command Line Tools. Multiple MySQL databases or SQL Server databases (up to 30) or Oracle database schemas can be created on a given DB Instance. The last part of that quote, "Multiple MySQL databases or SQL Server databases (up to 30) Oracle database schemas" I interpret to mean that you can have an "unlimited" number of databases on an RDS MySQL or Oracle instance but only 30 databases on an MS SQL Server instance ("unlimited" meaning not limited by the RDS infrastructure itself). This was asked in the Stackoverflow question Does Amazon RDS support multiple databases per instance?. The answer quoted an older version of the FAQ. What I am looking for is an Amazon document that clarifies this question, or else someone who has experience using Amazon RDS who can attest what the situation actually is.

  • How can I connect integrated webcam with virtualbox

    - by Mike Stumpf
    I am trying to use a Windows XP VM for VirtualBox on my Windows 8.1 laptop. I have tried the usual attaching USB device but I get an error saying "USB device is busy with previous request". My webcam is not active in any applications and this happens after a clean reboot of the host, the guest, and VirtualBox. Here are the details: Host -HP Pavilion 17 Notebook PC (stock) -Windows 8.1 -AMD A10-5750M APU -HP Truevision HD (integrated webcam) VM I got the VM here: http://www.modern.ie/en-us/virtualization-tools VirtualBox -VirtualBox 4.3.12 installed -VirtualBox Extension pack installed -Guest additions are installed for 4.3.12 -Enable USB Controller is checked -It does not matter if enable 2.0 controller is checked or not -It does not matter if a USB device filter is set up for the webcam or not -Here is the error message: Failed to attach the USB device DDFEQ01G45BFBV HP Truevision HD [0004] to the virtual machine IE8 - WinXP. USB device 'DDFEQ01G45BFBV HP Truevision HD' with UUID {7a2e2a45-974d-482b-9b4e-9f9abbcd0ebb} is busy with a previous request. Please try again later.

  • How to setup an IPSec / GRE tunnel on Windows Server 2008

    - by qbeuek
    I have a Windows Server 2008 that has a single network interface configured with a public IP address. My business partner has a private network. From my server, I need to access all the devices on his private network, and those devices must be able to access my server. My business partner has a standard solution for these requirements. They will setup an IPSec + GRE tunnel to my server. They told me, that I will need an additional public IP address for this to work. If it really is necessary, there is no problem, I can get an additional public IP address, although it will be assigned to the same physical network interface. I assume that on my server I will have both public IP addresses and also the private IP address from the tunnel (the same that is visible for the devices inside the private network). What alternatives do I have? Is it possible to configure this tunnel on my Windows Server 2008? Can it be done using only Windows tools, or do I need an additional free / commercial VPN software? If it cannot be done directly on Windows, can I setup an additional virtual machine running Linux, that will handle the IPSec + GRE tasks? How to do it? If it cannot be done on a virtual linux box, will I have to buy and setup a Cisco router to handle the IPSec + GRE tasks? Thanks for your opinions. I'm watching this question to clarify any issues or questions.

  • Mac Mini drive problems but SMART verified: bad hard drive or controller?

    - by Zac Thompson
    I have a 3-year-old Intel Mac Mini at home. About a month ago, it stopped booting from the hard drive (internal, SATA, 80GB). I tried booting from the Install Disc to repair the filesystem but Disk Utility was unable to do so ("invalid node structure"). I was also unable to use the hard drive in the Terminal from the Install Disc nor from an Ubuntu boot CD ("DRDY err"). I could see the contents of some directories, but others would give an error and I would get failures when trying to copy files. At this point I was sure the filesystem was hosed and I'd want to reformat at least. DiskWarrior was able to let me retrieve the data files I was interested in, which are now copied to an external hard drive, but it reported a high number of problems ("speed reduced by disk malfunction" count was over 2000) when in the process of trying to rebuild the directory for the drive. It also would not let me use the rebuilt directory to replace the one on the drive; it claimed the disk errors prevented recovery in this way. Under normal circumstances I would now assume that the drive itself was going bad: DiskWarrior's "disk malfunction" error above is supposed to imply hardware problems. My initial plan was to buy a replacement for the internal 2.5" drive. However: Disk Utility, command-line tools and DiskWarrior had reported all along that the SMART status of the drive was okay/Verified. So I'm now worried that the drive hardware is actually fine, and that the problems were due to a disk controller that has gone "bad" somehow. If this is the case, I'll probably just replace the whole computer. Any advice on how I can tell what is to blame? I don't have a lot of extra hardware sitting around, so I don't have the option of simply dropping the drive in another machine or popping another hard drive inside the Mini.

  • Dedicated server automatic backup solution

    - by Luigi
    I have a dedicated Ubuntu web server in a cloud environment, and I am looking for a nice way to do automated backups. I would like to backup some directories with web apps, and all my MySql databases. As for destination: make snapshots every two hours localy, and every six hours to a remote ftp server. Also delete backup archives older than seven days(localy + ftp), and notify on any problems by email. Now to achieve some of this functionality I use cron + shell script, and http://www.mysqldumper.net/, but really that doesn't answer my needs. Mysqldumper doesn't know automaticly about new databases, and shell script does not notify on problems. It's something I have to check out from time to time, and i don't have trust for. I googled a while, and seems like most people solve this stuff with shell scripts. Is this a method you can trust? Are there any web-gui tools, I'm missing? Maybe there is a smarter startegy for doing this? I'm a little bit confused.

  • how to initialize two logical drives on a HP P400i controller without reboot

    - by John
    What I am trying to do is initialize two logical drives on a HP P400i embedded controller without a reboot of the system here my current Array config: array A (SAS, Unused Space: 0 MB) logicaldrive 1 (17.9 GB, RAID 5, OK) logicaldrive 2 (17.9 GB, RAID 5, OK) logicaldrive 3 (75.9 GB, RAID 5, OK) logicaldrive 4 (25.0 GB, RAID 5, OK) physicaldrive 1I:1:1 (port 1I:box 1:bay 1, SAS, 72 GB, OK) physicaldrive 1I:1:2 (port 1I:box 1:bay 2, SAS, 72 GB, OK) physicaldrive 1I:1:3 (port 1I:box 1:bay 3, SAS, 72 GB, OK) array B (SAS, Unused Space: 0 MB) logicaldrive 5 (99 MB, RAID 0, OK) logicaldrive 6 (68.2 GB, RAID 0, OK) physicaldrive 1I:1:4 (port 1I:box 1:bay 4, SAS, 72 GB, OK) windows 2003 machine running the HpCISs2.sys driver version 6.20.0.32 . I have the ACU and ACU CLI tools installed version 8.28.13.0, P400i firmware version 2.74 . Now what I'd like to do is removes the physical drive 1I:1:4 and delete the two logical drives in array B. then insert a new drive in to bay 4 that contains two new logical drives and have them show up in array B again. So far after I remove the drive and delete the failed logical drives, I insert the new drive and run HPacucli rescan. I get the new drive to show up as unassinged physical drive but I cant figure out now to "for lack of a better word" mount the 2 logical drives on the new unassinged disk. If I reboot the system the array controller picks up the new fourth drive and creates Array B with the drives without problem but I'd really like to not have to reboot the server. Any ideas?

  • OpenBSD logins via SSH seem to be ignoring my configured radius server

    - by Steve Kemp
    I've installed and configured a radius server upon my localhost - it is delegating auth to a remote LDAP server. Initially things look good: I can test via the console: # export user=skemp # export pass=xxx # radtest $user $pass localhost 1812 $secret Sending Access-Request of id 185 to 127.0.0.1 port 1812 User-Name = "skemp" User-Password = "xxx" NAS-IP-Address = 192.168.1.168 NAS-Port = 1812 rad_recv: Access-Accept packet from host 127.0.0.1 port 1812, id=185, Similarly I can use the login tool to do the same thing: bash-4.0# /usr/libexec/auth/login_radius -d -s login $user radius Password: $pass authorize However remote logins via SSH are failing, and so are invokations of "login" started by root. Looking at /var/log/radiusd.log I see no actual log of success/failure which I do see when using either of the previous tools. Instead sshd is just logging: sshd[23938]: Failed publickey for skemp from 192.168.1.9 sshd[23938]: Failed keyboard-interactive for skemp from 192.168.1.9 port 36259 ssh2 sshd[23938]: Failed password for skemp from 192.168.1.9 port 36259 ssh2 In /etc/login.conf I have this: # Default allowed authentication styles auth-defaults:auth=radius: ... radius:\ :auth=radius:\ :radius-server=localhost:\ :radius-port=1812:\ :radius-timeout=1:\ :radius-retries=5:

  • Windows 7 64-bit installation from alternative media (no DVD/USB Flash drive)

    - by Niels Willems
    Greetings I currently have Windows 7 x86 installed on my computer. I want to install Windows 7 x64 on a different partition on my computer. However there is a little issue, I cannot run the x64 install from Windows 7 x86 which I currently have. I was planning to Install Windows 7 x64 on another partition to then boot up from that partition to install it on the partition I actually want my OS on. Once that is complete I could just format the partition from the Windows 7 x64 that I didn't need anymore. But the installer will not run from the x86 version of Windows 7 even though I do not want to upgrade that Windows directly. The reason I'm doing this in such a weird way is that my optical drive is broken and I'm really not into buying a new one since I would use it like once every year or so. I also don't have a USB Flash Drive which is big enough to hold the installation files. As far as I'm aware I cannot use an external hard drive such as this one, which I do have. Are there any alternatives in which I can install Windows 7 x64 or am I forced into buying a USB Flash Drive or new optical drive? Thank you in advance for your replies. Edit: This picture shows my current partitions on my laptop. I want to get Windows 7 x64 on the C partition but have to install it first on the F partition to then boot up the F partition windows to format C and install x64 on that one. My external drive is J. Edit 2: No alternative computer which has a DVD drive, install files are located on an iso from MA3D. To install my 32 bit version I mounted the ISO in Daemon Tools to replace my Windows Vista but since I cannot run 64 bit into my 32 bit OS this doesn't work.

  • Identifying Hard Drive as performance bottleneck for desktop machines

    - by Programming Hero
    I'm working in a development team where we all use laptops so we can work in multiple locations. These laptops are proving notoriously slow for development work, but at a glance they all look to have the specification for a much faster experience: CPU - Intel Core 2 Duo T7500 Memory - 2GB of RAM We all experience the biggest delays when the hard-drives are being accessed, particularly when swap-files are being thrashed. After doing a little bit of profile, a colleague discovered that our HDDs are seeing Read/Write speeds of about 10MB/sec. This seems abnormally low and we believe it the cause of the problem. Sensibly (though somewhat annoyingly) our business wont blow money on faster drives just to see if it fixes the problem; we need to illustrate this is definitely the problem and that buying some solid-state drives will make it go away. I need some way of showing how 90% of the system resources aren't being used over the course of a day, and that whenever there is utilization, it's all in HDD reads or writes. Are there any tools I could use to provide this information? Does it seem likely the problem is going to be fixed by a faster drive? Should I be looking for alternatives?

  • Windows Home Server installation fails because it can't find the DVD drive anymore

    - by BBlake
    I've got an old Dell Dimension 8300 desktop I decided to convert into a WHS box. I popped in a pair of 1 TB SATA drives, which were recognized fine by the BIOS and the currently installed OS (XP), so I decided to go ahead and install WHS. Near the end of the installation, WHS acts like it can no longer find the DVD drives (either of them, the box has a DVDROM and a DVDRW). The specific error is gives is the "Can't configure storage" error. I've found several forums where people say they get this error if they remove the boot DVD during the installation (at the time of the first reboot). However, I never removed the DVD. After the error, if fails into WHS, so it did mostly install and I can work with WHS. However, it refuses to recognize the network card, video card and while it shows the two DVD drives, any CD/DVD I insert in either drive the system says is corrupted and unreadable, even though none of them are. I've tried several reinstalls both removing and not removing the DVD, but the result is the same regardless. Any other tricks anyone found? If I can't figure this out, maybe I'll just install SBS2008 and fake it up to be similar to WHS with some addin tools. Shouldn't be too hard to create something since WHS is based on SBS2003 anyway.

  • How Do I Install Latest Java Plugin on Ubuntu 8.04 LTS with Custom Firefox 3.6.3?

    - by Volomike
    I have Ubuntu 8.04 LTS and will need to remain on that for awhile as I am a programmer and cannot disturb what I'm doing in the middle of a project. As you know, it doesn't want to install the latest Firefox by default and keeps me in the stone age. So, I had to install my own Firefox. I did so and with relative ease I was able to install the Flash plugin using the normal 'ln -s' technique one usually does with /usr/lib/firefox/plugins. Now I need to do a Gotomypc.com task and it requires Java -- moan -- so I need to figure out how to install Java. I downloaded and installed the latest Java plugin in /usr/java, and I do see underneath that layer of folders a plugins folder with a .so file. So, I went to /usr/lib/firefox/plugins and did this: ln -s /usr/java/jre1.6.0_20/plugin/i386/ns7/libjavaplugin_oji.so Then, I also read on the web that one has to create a ~/.mozilla/plugins folder, cd into it, and then run the same ln -s command again. Another site recommended finding one's ~/.mozilla/firefox and renaming it to ~/.mozilla/firefox.old (after you backed up your bookmarks) and then launching firefox again so that it creates ~/.mozilla/firefox and uses the new Java plugin. Well, all these attempts have completely failed and it is incredibly frustrating. I do about:plugins to see my plugins and all I get are the Flash and the default null plugin. I do not see the Java one. Also, they said on my tools menu with Firefox 3.6.3 I would see a Java Console menu and I don't see that either. I found a pluginreg.dat somewhere deep under ~/.mozilla/firefox, but it does not list the Java plugin inside -- only Flash and the null plugin. Please help me install Java. I need to help a client out and need to connect to his PC remotely with gotomypc, which requires Java inside firefox.

  • Error importing large MySQL dump file which includes binary BLOBs in Windows

    - by Daniel Magliola
    I'm trying to import a MySQL dump file, which I got from my hosting company, into my Windows dev machine, and i'm running into problems. I'm importing this from the command line, and i'm getting a very weird error: ERROR 2005 (HY000) at line 3118: Unknown MySQL server host '+?*á±dÆ-N+Æ·h^ye"p-i+ Z+-$?P+Y.8+|?+l8/l¦¦î7æ¦X¦XE.ºG[ ;-ï?éµ?º+¦¦].?+f9d릦'+ÿG?-0à¡úè?-?ù??¥'+NÑ' (11004) I'm attaching the screenshot because i'm assuming the binary data will get lost... I'm not exactly sure what the problem is, but two potential issues are the size of the file (2 Gb) which is not insanely large, but it's not trivially small either, and the other is the fact that many of these tables have JPG images in them (which is why the file is 2Gb large, for the most part). Also, the dump was taken in a Linux machine and I'm importing this into Windows, not sure if that could add to the problems (I understand it shouldn't) Now, that binary garbage is why I think the images in the file might be a problem, but i've been able to import similar dumps from the same hosting company in the past, so i'm not sure what might be the issue. Also, trying to look into this file (and line 3118 in particular) is kind of impossible given its size (i'm not really handy with Linux command line tools like grep, sed, etc). The file might be corrupted, but i'm not exactly sure how to check it. What I downloaded was a .gz file, which I "tested" with WinRar and it says it looks OK (i'm assuming gz has some kind of CRC). If you can think of a better way to test it, I'd love to try that. Any ideas what could be going on / how to get past this error? I'm not very attached to the data in particular, since I just want this as a copy for dev, so if I have to lose a few records, i'm fine with that, as long as the schema remains perfectly sound. Thanks! Daniel

  • How to tell which process is hogging my CPU when they don't add up to 100%?

    - by endolith
    Ubuntu's System Monitor applet shows 100% CPU usage continuously. If I click it, the resources tab shows it at 100% continuously, too. If I go to processes, though, to find out which process is the culprit, there is nothing above 10%. If I run top there is nothing above 10%. The individual processes do not add up to 100%. I try killing lots of processes, but the overall usage continues to be 100%. How can I find out what's hogging the CPU? This is an unusual situation on a computer I use daily, which is never anywhere near 100% CPU unless I'm doing something that requires it (like loading 32 Firefox tabs), after which it goes back to a normal idle level. It's not a new install or anything. There is no reason the processor should be maxed out. I'm not sure when it started or if I changed something that caused it to happen. Normally I would use top or System Monitor and find the process that had gone out of control, but I can't find anything with those tools this time. It persists after reboots and everything. And the processor is obviously hot, so it's not an erroneous reading. Update: I tried killing every process, one at a time, until the problem went away, and killing vino-server finally fixed it, even though that process never went above 5%. I had enabled Remote Desktop a few days ago (and have obviously now disabled it). But the question remains: How did a single process manage to use 100% CPU while top only showed that process at 5%? How do I identify culprits like this in the future? Looks like I'm not the only one who's had this problem: Still a problem in both jaunty & karmic. Interestingly, both System Monitor & htop do not show the sum of individual processes being anywhere near 100% cpu.

  • How to detect/list rogue computers connected to a WIFI network without access to the Wifi Router interface?

    - by JJarava
    This is what I believe to be an interesting challenge :) A relative (that leaves a bit too far to go there in person) is complaining that their WIFI/Internet network performance has gone down abysmally lately. She'd like to know if some of the neighbors are using her wifi network to access the internet but she's not too technically savvy. I know that the best way to prevent issues would be to change the Router password, but it's a bit of a PITA having to re-configure all wifi devices... and if the uninvited guest broke the password once, they can do it again... Her wifi router/internet connection is provided by the telco, and remotely managed so she can log-on to their telco account's page and remotely change the router's Wifi password, but doesn't have access to the router status page/config/etc unless she opts out of the telco's remote support and mainteinance service... So, how could she check if there are guests in the wifi with this restrictions and in the most "point and click way"? In this case I'd probably use nmap to look for other devices in the network, but I'm not sure if that's the easiest way to do it. I'm not a wifi expert, so I don't know if there are any wifi-scanning utils that can tell us who's talking to the router... Lastly, she's a Windows user as I guess that'll influence the choice of tools available Any suggestions more than welcome Regards!

  • Durability of Websockets Server

    - by smitchell360
    I am starting to experiment with websockets. Does anyone know of a websockets server (open source or paid) that provides a durable store of the websocket "channel"? All of the examples that I have found do not address durability -- if a websockets server goes down, all "channel" data is lost. Services such as Pusher do not really discuss whether they address the durability issue (and I have not received a response from tech support yet). Happy to roll my own, but would rather not reinvent the wheel. EDIT: I'm not looking for websockets 101 information. That is readily available and understood. I'm looking for a server (open source or paid) that supports websockets and has a durable store for the websocket data so that, in the event that a server fails, a new server can take over where the original one left off. Two main purposes: 1. support failover scenarios contemplated by the websockets Network Working Group http://tools.ietf.org/html/draft-ibc-websocket-dns-srv-02#section-5.1 (most importantly so that missed messages are sent when a client connects to a failover server) 2. support scenarios where new subscribers must receive all past messages that were published. Of course this can be handled at the application layer...but that is not what I am looking for.

  • RoboCopy errors on Windows Server 2008

    - by Steve
    I am getting bizarre error with RoboCopy in Server 2008. It will randomly hang with "The specified network name is no longer available." error. Once that happens, it will continue to fail on the retries. But of course the remote server IS still available on the network and can be reached with other tools. I think it must be somehow permission related but I can't figure out what is wrong. Any ideas would be much appreciated. Other info: Options : *.* /S /E /COPY:DAT /NP /R:10 /W:30 If I turn on the /B option it will fail 100% of the time at the very beginning (that's why I think it has to be somehow permission-related) The two servers are standalone and I am doing a NET USE command prior to the robocopy It does not matter what user account on the remote server. Tried both Administrator and another user which was also a member of the local Administrators group UAC is turned off on both sides It is not always the same file that hangs. Sometimes it will get through half or more and sometimes it will fail on the first file

  • Very slow browsing shared folder XP client/host

    - by Ickster
    I have a pretty straightforward setup where I'm storing media files on an XP pro machine, and sharing the folder to be accessed by other XP pro machines around the house. (Typically, there's only one client accessing the share at a time, although there may be several with the share mounted.) It's been working just fine for years, but I've recently started having some problems. A couple of days ago, the host PC had power disconnected while it was running. It was restarted and everything seemed fine initially, but since then browsing the shared folder from client machines has been extremely slow and actually reading data is all but impossible. The problem exists in every access method I've tried: Windows Explorer, VLC dialogs, command line, etc. My first thought was that the disk was experiencing problems, but there are no problems viewing the files locally on the host machine. My second thought was that there was a network problem on the host machine, so I removed and reinstalled drivers for the NIC with no change. My third thought was that there might've been a problem elsewhere on the network, so I swapped out hardware to no avail. I'm regrouping and trying to come up with a methodical approach to figuring out what might be wrong. I would of course be thrilled if you can suggest specific problems (Microsoft KB articles, etc.) that I might check, but I'm not expecting a silver bullet. If you can help me outline an approach to identify the problem (including recommended tools, e.g., disk checkers, network analyzers, etc.) I'd greatly appreciate it.

  • GRE Tunnel over IPsec with Loopback

    - by Alek
    Hello, I'm having a really hard time trying to estabilish a VPN connection using a GRE over IPsec tunnel. The problem is that it involves some sort of "loopback" connection which I don't understand -- let alone be able to configure --, and the only help I could find is related to configuring Cisco routers. My network is composed of a router and a single host running Debian Linux. My task is to create a GRE tunnel over an IPsec infrastructure, which is particularly intended to route multicast traffic between my network, which I am allowed to configure, and a remote network, for which I only bear a form containing some setup information (IP addresses and phase information for IPsec). For now it suffices to estabilish a communication between this single host and the remote network, but in the future it will be desirable for the traffic to be routed to other machines on my network. As I said this GRE tunnel involves a "loopback" connection which I have no idea of how to configure. From my previous understanding, a loopback connection is simply a local pseudo-device used mostly for testing purposes, but in this context it might be something more specific that I do not have the knowledge of. I have managed to properly estabilish the IPsec communication using racoon and ipsec-tools, and I believe I'm familiar with the creation of tunnels and addition of addresses to interfaces using ip, so the focus is on the GRE step. The worst part is that the remote peers do not respond to ping requests and the debugging of the general setup is very difficult due to the encrypted nature of the traffic. There are two pairs of IP addresses involved: one pair for the GRE tunnel peer-to-peer connection and one pair for the "loopback" part. There is also an IP range involved, which is supposed to be the final IP addresses for the hosts inside the VPN. My question is: how (or if) can this setup be done? Do I need some special software or another daemon, or does the Linux kernel handle every aspect of the GRE/IPsec tunneling? Please inform me if any extra information could be useful. Any help is greatly appreciated.

  • How can I write automated tests for iptables?

    - by Phil Frost
    I am configuring a Linux router with iptables. I want to write acceptance tests for the configuration that assert things like: traffic from some guy on the internet is not forwarded, and TCP to port 80 on the webserver in the DMZ from hosts on the corporate LAN is forwarded. An ancient FAQ alludes to a iptables -C option which allows one to ask something like, "given a packet from X, to Y, on port Z, would it be accepted or dropped?" Although the FAQ suggests it works like this, for iptables (but maybe not ipchains as it uses in the examples) the -C option seems to not simulate a test packet running through all the rules, but rather checks for the existence for an exactly matching rule. This has little value as a test. I want to assert that the rules have the desired effect, not just that they exist. I've considered creating yet more test VMs and a virtual network, then probing with tools like nmap for effects. However, I'm avoiding this solution due to the complexity of creating all those additional virtual machines, which is really quite a heavy way to generate some test traffic. It would also be nice to have an automated testing methodology which can also work on a real server in production. How else might I solve this problem? Is there some mechanism I might use to generate or simulate arbitrary traffic, then know if it was (or would be) dropped or accepted by iptables?

  • Fresh Install of SQL Server 2008 doesn't install managment studio. Help!

    - by Jordan S
    Ok I am running Windows 7, 64 bit. I cleaned of SQL server 2005 completely off my system leaving only SQL Compact Edition. I went here http://www.microsoft.com/downloads/details.aspx?FamilyID=01af61e6-2f63-4291-bcad-fd500f6027ff&displaylang=en and installed SQL Server 2008 Express Edition Service Pack 1. After the install, under my start bar menu all i have for SQL configuration tools are the Configuration Manager, Error and Usage Reporting and the Install Center. I don't have the SQL Managment Studio. So I went here http://www.microsoft.com/downloads/details.aspx?FamilyID=08e52ac2-1d62-45f6-9a4a-4b76a8564a2b&displaylang=en and downloaded the SQL Server 2008 Management Studio Express but when I try to install it I get a warning says This program has known compatibility issues and that I need to Install SQL Server 2008 Service Pack 1. I thought that is what I installed. So, I tried to continue running the install but I then get an error message that says Invoke or BeginInvoke can not be called on a Form before it is opened... How can I check if Service pack 1 is installed or not? What should I do?

  • Managing multiple Apache proxies simultaneously (mod_proxy_balancer)

    - by Hank
    The frontend of my web application is formed by currently two Apache reverse proxies, using mod_proxy_balancer to distribute traffic over a number of backend application servers. Both frontend reverse proxies, running on separate hosts, are accessible from the internet. DNS round robin distributes traffic over both. In the future, the number of reverse proxies is likely to grow, since the webapplication is very bandwidth-heavy. My question is: how do I keep the state of both reverse balancers / proxies in sync? For example, for maintenance purposes, I might want to reduce the load on one of the backend appservers. Currently I can do that by accessing the Balancer-Manager web form on each proxy, and change the distribution rules. But I have to do that on each proxy manually and make sure I enter the same stuff. Is it possible to "link" multiple instances of mod_proxy_balancer? Or is there a tool out there that connects to a number of instances, and updates all with the same information? Update: The tool should retrieve the runtime status and make runtime changes, just like the existing Balancer-Manager, only for a number of proxies - not just for one. Modification of configuration files is not what I'm interested in (as there are plenty tools for that).

  • Is Subversion(SVN) supported on Ubuntu 10.04 LTS 32bit?

    - by Chad
    I've setup subversion on Ubuntu 10.04, but can't get authentication to work. I believe all my config files are setup correctly, However I keep getting prompted for credentials on a SVN CHECKOUT. Like there is an issue with apache2 talking to svnserve. If I allow anonymous access checkout works fine. Does anybody know if there is a known issue with subversion and 10.04 or see a error in my configuration? below is my configuration: # fresh install of Ubuntu 10.04 LTS 32bit sudo apt-get install apache2 apache2-utils -y sudo apt-get install subversion libapache2-svn subversion-tools -y sudo mkdir /svn sudo svnadmin create /svn/DataTeam sudo svnadmin create /svn/ReportingTeam #Setup the svn config file sudo vi /etc/apache2/mods-available/dav_svn.conf #replace file with the following. <Location /svn> DAV svn SVNParentPath /svn/ AuthType Basic AuthName "Subversion Server" AuthUserFile /etc/apache2/dav_svn.passwd Require valid-user AuthzSVNAccessFile /etc/apache2/svn_acl </Location> sudo touch /etc/apache2/svn_acl #replace file with the following.

  • Help with memory usage issues on VPS

    - by Niall Collins
    Hi there, I am running a VPS server with 6 .net web sites/applications running on it. I am having issues with performance on the server, mainly it running out of memory. I contacted the company that lease the server to me and they told me it was because I also had sql server 2008 express also running on the server. So I went ahead and removed this, uninstalled etc. However I still seem to be having issues. For example at present, looking at resource consumption, the virtual memory is: ID: vprvmem Current Use: 894,328,832 bytes Limit: 1,073,741,824 bytes This means useage of ~80%. Is there any way I can check out exactly that applications, web sites, software is taking up most of the servers memory, so I can look at rectifying it. I feel that 80% is much to high to allow for contingency for a spike in traffic. I have got extra memory resources added to the box recently, but I would prefer finding the source of the problem rather than throwing extra memory at it. Maybe these levels are correct and alls running ok, but would like to investigate it to make sure. My knowledge of hardware is limited as I mostly deal in the spectrum of software. So any tools out there that can help me or any pertient advice.

  • Identify differences between MP3 files

    - by Thingomy
    I have 2 old similar directory trees with MP3 files in them. I am happily using tools like diff and Rsync to identify and merge the files that are only present on one side, or are identical, I'm left with a bunch of files that are bitwise different. On running diff over a pair actually different files, (with -a tag to force text analysis) it produces incomprehensible gibberish. I have listened to files from both sides, and they both seem to play fine (but at nearly 10 minutes per song, when listening to them twice each, I haven't done many) I suspect the differences are due to some player in the past "enhancing" my collection by messing about with ID3 tags, but I can't be certain. Even if I identify differences in ID3 tags, I would like to confirm that no cosmic ray or file copy error issues have damaged any of the files. One method that occurs to be is finding the byte locations of the differences, and ignoring all changes in the first ~10kb of each file, but I don't know how to do this. I have on the order of a hundred or so files that differ across the directory tree. I found How to compare mp3, flac audio data in a file, ignoring header data (ID3 tag) etc.? -- but I can't run alldup due to being Linux only, and from the sounds of it, it would only partially solve my issues anyway.
