• IIS7 Custom ASP.NET Errors

  - by Nathan

  I'm trying to setup a custom error page for the IIS 7 404.13 (Content length too large) error. Here's the relevant sections of my web.config file: <system.webServer> <httpErrors errorMode="Custom" existingResponse="Replace"> <remove statusCode="404" subStatusCode="13" /> <error statusCode="404" subStatusCode="13" prefixLanguageFilePath="" path="/FileUpload/Test.aspx" responseMode="ExecuteURL" /> </httpErrors> <security> <requestFiltering> <requestLimits maxAllowedContentLength="10240" /> </requestFiltering> </security> </system.webServer> The response that is being sent back to the server is blank. The Test.aspx file is not blank. Any idea what's going on here?

• 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.

• Install EncFS on Mountain Lion (OS X 10.8)

  - by emempe

  I use EncFS to encrypt my files. So far, I've been using the installer provided by BoxCryptor. It packs EncFS 1.7.4, MacFuse and MacFusion in one installer and works nicely on Mountain Lion. But MacFuse is not actively developed and most people might replace it with Fuse for OS X or something similar. Are there other packaged installers for EncFS? Or do you always compile EncFS from source? If so, is there a tutorial on how to compile?

• Replacing notebook SATA hard disk with SSD without reinstalling

  - by Graeme Donaldson

  So there's a notebook (Lenovo Thinkpad Z61m) with a SATA hard disk, the SATA controller is configured for native AHCI operation & the OS is Windows XP. The hard disk is going to be replaced with an SSD which is larger. I have an idea of how I'm going to do this, but I want to be sure there isn't something obvious I'm missing. Connect external USB drive Boot some flavour of Linux live CD Use dd to clone the SATA disk to the external drive Power off and replace the SATA disk with the SSD Boot the live CD Use dd to clone back from the external drive to the SSD Does anyone have anything to add?

• Migrating Windows 2008 R2 to Windows 2012 (migrate all FSMO too)

  - by Mauro

  I own 2 server with Windows 2008 R2, both DC. The first one is of course the Primary DC (with all FSMO). What I would like to do is ro dcdemote the 2nd DC, remove it from domain and replace the Windows 2008 r2 with 2012. I will then rejoin this 2nd DC (with the new 2012 server) to domain and dcpromo it (Server Management). After this is a new DC I would like to temporary transfer all the FSMO to this server, while I'm doing the same operation on what is actually the Primary DC. Is this a stupid solution? What I would like to do is a clean installation, I don't want to upgrade directly those systems. Suggestions? Ideas? Thanks, Mauro

• Google Account Changes that Messed Up My Ability to Manage Sites

  - by A Yearwood

  I hope you can help... I have a google account that I use to manage my church website. This account is set up with my work email address. My work (a school system) is in the process of changing us all over to use google accounts to replace Outlook. When I logged in to this new account (which is my same email address) it no longer lets me manage my google site. Under my dashboard I can see that my data is still there, but when I try to "manage" my site it says I don't have one and re-directs me to my school's account. Thanks in advance. A Yearwood

• Migrating XenServer VMs from Intel to AMD servers

  - by John Smith

  I need to replace my XenServer 6.1 resource pool hardware. I currently run Intel hardware and I have to move to AMD hardware (corporate politics and budget stuff, blah blah blah). I have downtime available so I can use cold migration - live migration is not required. I will also have the new hardware (AMD) alongside the old hardware (Intel). The XenServer docs say there may be problems exporting from one arch and importing to another "may not work" - http://docs.vmd.citrix.com/XenServer/6.1.0/1.0/en_gb/guest.html#importing_vms - but mentions nothing about simply turning off the VM on one arch and then powering it back on new arch. VMs are a mix of OS - some Windows, some Linux, multiple versions. Is this something that can be done with no problems, or are there problems I need to be aware of?

• CloudFormation - How to start a Windows Service with cfn-init

  - by Edwin

  I'm creating a CloudFormation Stack that will install and start a service on a Windows Instance. I've figured out how to install the service, but how do I start the service using cfn-init? The examples seem to all use linux, as there is a reference to "sysvinit" How do I structure AWS::CloudFormation::Init so that cfn-init will start windows services after installing them? Do I leave in the sysvinit, replace it with something else, take it out? ps: I'm referring to how to start services by providing information to AWS::CloudFormation::Init.services. Also, It would be nice to know how "packages" work for windows. AWS's announcemnet says that packages are supported on Windows but there is no Windows specific documentation

• Why can't I grant exec on dbms_lock.sleep() OR create a procedure using it (but I can run it fine on its own)

  - by Richard Green

  I am trying to write a small bit of PL/SQL that has a non-CPU burning sleep in it. The following works in sqldeveloper begin dbms_lock.sleep(5); end; BUT (as the same user), I can't do the following: create or replace procedure sleep(seconds in number) is begin dbms_lock.sleep(seconds); end; without the error "identifer "DBMS_LOCK" must be declared... Funny as I could run it without a procedure. Just as strange, when I log in as a DBA, I can run the command grant exec on dbms_lock to public; and I get ERROR at line 1: ORA-00990: missing or invalid privilege This is oracle version "Oracle Database 11g Express Edition Release 11.2.0.2.0 - 64bit Production"

• Directly editing IIS 7 applicationHost.config configuration file

  - by lunadesign

  I know that IIS 7+ now uses XML config files instead of the metabase. I also know that if I edit a web.config file for a given site, IIS automagically detects the changes and implements any corresponding config changes. However, does this also apply to the server-level applicationHost.config settings file? (Its usually located in C:\windows\system32\inetsrv\config.) Specifically, is it safe to carefully edit this file instead of using IIS Manager or the appcmd command line utility? I couldn't find anything in the documentation that said it was okay or not okay to do this. I'm curious because I have to change the bindings for numerous sites from one IP to another. It would be much faster to simply do a global search and replace for the IP address in the config file instead of manually editing a few dozen sites in the GUI.

• Saving music wisely: Why save 'Queen - Bohemian Rhapsody.mp3' millions of times?

  - by hsmit

  As far as I'm concerned, Queen's song 'bohemian rhapsody' is one of the most popular songs all time. But for the purpose of this message you may replace this with another track. At the same time I think 60% of the digital-music listeners have this track. Sometimes we have multiple copies: different versions of the track, different devices, unwanted duplicates in download folders, itunes folders etc.. Wouldn't it be much smarter to store these songs only once? You can imagine various solutions for this. How would you accomplish this? Some criteria that may help you find an answer: It must reduce disk space It must remember which music belongs to you (DRM) It must use network traffic efficiently

• Open-source training class/room/instructor resource management software?

  - by Kyle Eli

  We're looking to replace an internal system used for managing training classes with something a bit more robust. Needs to be open-source or have a license level that grants access to source, and needs to be ASP.net (C# preferred, but could live with VB.net) Ultimately, we'll need to be able to assign facilities and instructors, manage attendees, send notifications, and build calendar views. We'll also be integrating with our website to allow on-line sign-up and other things for attendees to manage on their own. We do expect to implement quite a bit of it in-house, but we'd like as broad of a base to start from as we can get. Still, just a really good web-based meeting-room reservation system might make a good enough starting point. In list form: Meeting/training resource management softwareASP.net (C# or VB.net)Source availableWe're expecting to have to modify the software to meet all of our requirements

• Why is my CPU fan so loud?

  - by tiiquu

  I bought an old PC to use as a second PC. Everything is fine, except for one thing. The CPU fan is terribly loud! I did a lot with PCs but I never did much with CPU fans. If I want to replace it, what do I have to look for? The fan is 8cm long on each side and 11cm diameter. It is just clipped to the cooler. The PC is a P4 3 GHz. I don't want to spend much money, as I only paid 50 euro for the whole PC. I would prefer to buy a fan for 1-3 dollar or something at eBay but I am not quite sure which one I should buy (which fits). Can you advise?

• Apache vs Lighttpd: Weird behavior in reverse proxy mode.

  - by northox

  Context: I have an Apache server running in reverse proxy mode in front of a Tomcat java server. It handle HTTP and HTTPS and send those request back and forth to the Tomcat server on an internal HTTP port. Goal: I'm trying to replace the reverse proxy with Lighttpd. Problem: while asking for the same HTTPS url, while using Apache as the reverse proxy, the Tomcat server redirect (302) to an HTTPS page but with Lighttpd it redirect to the same page in HTTP (not HTTPS). Question: What does Lighttpd could do different in order to have a different result from the backend server? In theory, using Apache or Lighttpd server as a reverse proxy should not change anything... but it does. Any idea? I'll try to find something by sniffing the traffic on the backend tomcat server.

• Force10 S60 remote management

  - by StaringSkyward

  We've got a Force10 S60 switch to replace an older Cisco. I can't find a way to give the switch itself an IP address on the local VLAN so I can ssh to it. The config guide talks about using either a management interface on a separate management network or dedicating e.g. a gigabit port as a management port with a dedicated IP address. Ideally I would like to do what we do currently with the Cisco switches, which is in effect give the entire switch an IP so it can be reached from any host on the same VLAN without having to use up a physical port on the switch or physically connect the management port to another device. Is this possible with the S60 and if so, how would you give it, say the address 10.0.1.1 in vlan 10 (10.0.1.1/24)? Thanks!!!

• Set-and-forget Windows backup software with NAS-support?

  - by Evert

  Hi all, I am looking for set-and-forget backup software for Windows (Vista & 7, and if possible XP/2003). The idea is that it runs in the background on the clients, and does its thing towards a network-share. In case the HDD of one of these clients spontaneously combusts, all I want to have to do is: replace the drive, insert a USB-stick, boot from it, and restore the machine. It should support drives which use [ICH]-RAID. What are my options here? It looks like WHS meets all the requirements, but I am curious about my other options here.

• Replacing a W2K3 Domain Controller - what do I need to know?

  - by Marko Carter

  I have a network of around 70 machines, currently with two DCs both running Windows Server 2003 (DC0 & DC1). DC0 is a five year old Poweredge 1850 and has recently become increasingly flakey, and in the past fortnight has fallen over twice. I want to replace this machine, but I'm cautious as there is huge scope for this sort of thing to go wrong. The way I imagine doing this is building a new machine then doing a DCPROMO and running three domain controllers for a month or so until I'm happy that everything is working as it should be before retiring the old machine. Particular areas of concern are the replication of roles from the current controllers (GP settings for instance) and the ramifications of switching off the machine that has, up until now, been the 'primary'. If there are compelling reasons to use Server 2008 I'm willing to do so, however I don't know if this would cause problems with my exisiting 2003 machines. Any advice on best practice or previous experiences would be most welcome.

• How can I permanently remove default root hints from a Server 2008 DNS server?

  - by TonyD

  My network exists in private address space and I am unable to perform DNS lookups against DNS servers on the internet directly (blocked by firewall). There are other networks that exist in the same private address space as my network. I need to be able to perform DNS lookups for devices in these networks as well. There are 2 main internal DNS servers in this private address space, but not on my netowrk. I can perform DNS lookups against both of these servers for devices internal to our address space and names on the internet. I would like to permanently remove the root hints from our Server 2008 R2 DNS server and replace them with these 2 internal DNS servers. I have removed them from the dnsmgmt console, the C:\Windows\System32\DNS\cache.dns file, and from the RootDNSServers folder under the System folder in ADUC. Even so, they continue to repopulate into the root hints tab in the server properties for DNS after roughly an hour. Does anyone know how to permanently remove these entries?

• Mac Book Pro SSD

  - by LiamB

  I have a Mac Book Pro (I7 and 8 Gig Ram). I'm a developer - do a fair amount of .net via VMware but lots of Ruby and NodeJs on the Mac. I'm looking to extract some more performance and i think a SSD might be a good option. So I have 2 questions, Can I straight up replace the drive thats in there with a SSD or will this cause me problems? I have files on there as well as apps. What are my options in terms of available hardware.

• What to look for in a good cheap color laser printer?

  - by torbengb

  My old color inkjet is giving up, and I'm considering laser to replace it. There are several good questions about color laser printers, but none of them summarize the pro's and con's. So here goes: I am looking to buy a color printer for home use, mostly for photos (at least medium-quality) and also for low-volume b/w text. Duplex would be neat but not a must. One aspect per answer, please: What aspects should I consider, what should I look for, what should I avoid in a home color laser printer? I'll make this a community wiki because there won't be one single definite answer. I'll post a few ideas of my own but I'm hoping to get many useful insights.

• Making a Ligthing Flash Magento store with Nginx on AWS Elastic Beanstalk with Minimum Resource Utilization

  - by Junaid

  I'm going to install Magento on AWS Elastic Beanstalk t1.micro (free tier), on Windows or Linux + Nginx + Php-fpm + eAccelerator, CDN (cloudfront), MemcacheD. I will ask my developer to make my website as fast as it can be with as much as possible, minimum AWS utilization. My webstore will have <1000 SKUs and I'm not expecting the traffic without going into thorough SEO/PPC. Now I have three questions: Do I really need Nginx microcaching along with eaccelerator? Do I need AWS Elastic Load Balancer with t1.micro tier for the sake of scalability (as I have heard that magento is resource hungry application, may fully utilize t1.micro AMI) or can I replace AWS ELB with Nginx load balancer? In AWS Elastic Beanstalk?

• Anyone tried dd'ing Raidmembers?

  - by DusteD

  I want replace all disks in a 10 disk raid6 (linux software raid). I could do this by pulling a disk, let the array rebuild, rinse, repeat. But this would take a very long time, and cause 10 rebuilds, which would most likely stress all 10 disks much more than simply reading each disk through once. My question is thus: Could I just shut down the array, and dd each old disk to a new disk and then start the array with the 10 new disks? In an ideal world, I would build another server and just copy the data via network, but this is not an ideal world.

• Unable to boot to Ubuntu. Inconsistency in disk, X server didn't start. Illegal blocks in Inode

  - by becomingGuru

  I am unable to boot into my Ubuntu system. First I get that fsck died with exit status 4 Then I try to do it manually as prompted and I get that an Inode has illegal blocks and asked to clear it. Upon googling, I found that is because my HD has some problems I booted via Live cd and took a dd of the entire Ubuntu on an external HDD just in case. Is it safe to clear all the illegal blocks. How do I safely restore my environment if I replace my HD. Is there any thing i can do in the meanwhile to continue to use my laptop without significant loss of data. Perhaps a related error, the x server fails to start

• Simple, manageable DNS on EC2?

  - by dkulchenko

  I'm working on a large network of servers sitting on EC2, and need a way for the servers to know about each other's locations in the cloud. I thought the simplest way would be to use DNS, because if I replace the EC2 instance, I simply update the DNS record, and the rest of the servers will know about it (with names like users.db.mysoft.com, routing.mysoft.com, cluster1.memcached.mysoft.com). I'm considering setting up a master DNS server on a micro/small instance to accommodate this. I'd preferably need something that's as simple as a key-value store (hostname - IP) into which the platform could remotely add/remove entries. Can I do this with BIND? Or is there a better solution?

• Installing isolated instance of MySQL on Windows using silent install with .msi

  - by Abram

  I'm trying to write an installer for an internal application we wrote. After it installs our application it then installs MySQL using the .msi installer in silent mode. I specify the install dir and data dir to that of a directory within my application's install directory, such as: msiexec /i @@MYSQL_INSTALLER_FILE@@ /qn INSTALLDIR="@@INSTALL_DIR@@\MySQL\" DATADIR="@@INSTALL_DIR@@\MySQL\" USERNAME="@@DB_USER@@" PASSWORD="@@DB_PASS@@" (the @@variable@@'s are replace by my installer routine using InstallJammer) Once installed, I use mysqld.exe to install a windows service with a custom service name and defaults file like so: mysqld.exe --install CustomMySQL --defaults-file="@@INSTALL_DIR@@\MySQL\my.ini" This works fine as long as there is not already another instance of MySQL installed. If there is it silently fails to install MySQL. Running the msi installer manually (double-click) shows an error that a previous version is already installed and just aborts. Is there a way to automate installing MySQL as an isolated instance, regardless of whether another version/instance is already installed?
