  • A TDD Journey: 4-Tests as Documentation; False Positive Results; Component Isolation

    In Test-Driven Development (TDD) , The writing of a unit test is done more to design and to document than to verifiy. By writing a unit test you close a number of feedback loops, and verifying the functionality of the code is just a minor one. everything you need to know about your class under test is embodied in a simple list of the names of the tests. Michael Sorens continues his introduction to TDD that is more of a journey in six parts, by discussing Tests as Documentation, False Positive Results and Component Isolation.

  • "getpt failed: No such file or directory" when opening a terminal through VNC

    - by Michael
    I am running Debian Wheezy on my server, and have just installed a VNC server and Xfce. I have come across a problem: whenever I open a terminal emulator through VNC, I get an error box with this message: Failed to execute child. getpt failed: No such file or directory. This happens with every terminal I try to run. I can still run commands through SSH, however. It's just the terminal that won't open. Does anyone have any suggestions? /etc/fstab: proc /proc proc defaults 0 0 none /dev/pts devpts rw 0 0

  • Oracle VM repository creation seems contradictory to its server pool?

    - by Michael
    I found something contradictory in Oracle VM. Clustered server pool creation in Oracle VM would format my FC LUN as ocfs2 , and start o2cb & ocfs2 services to build cluster environment. After that, when I wanted to create repository on the serverpool, unexpectedly, it told me that the physical disk I chose which is also my FC LUN, already contains a file system. What a contradictory! So what, delete the file system in serverpool? If so, why created it before?! OVM> list physicaldisk Command: list physicaldisk Status: Success Time: 2012-09-10 06:44:42.660 Data: id:0004fb00001800007765e62381895f61 name:OVM_HDS OVM> create serverpool clusterenable=true virtualip=10.84.21.123 physicaldisk=OVM_HDS name=ovmserverpool Serverpool creation took quite a long time since my FC LUN was big. When the creation completed, my FC LUN was created as ocfs2 and o2cb & ocfs2 services were started on my ovm servers successfully. But then repository creation indeed throws me a big surprise ... OVM> create repository serverpool=ovmserverpool physicaldisk=OVM_HDS name=ovmrepo Command: create repository serverpool=ovmserverpool physicaldisk=OVM_HDS name=ovmrepo Status: Failure Time: 2012-09-10 06:23:44.656 Error Msg: com.oracle.ovm.mgr.api.exception.RuleException: OVMRU_002026E Cannot use or delete physical disk: OVM_HDS, it already contains a file system: [Pool filesystem for ovmserverpool] Mon Sep 10 06:23:44 CST 2012 What should I do now? Delete the filesystem using dd command? That would destroy the serverpool, right? I'm really confused. My OVM Manager version is 3.1.1.399 which is the latest. Any tips are appreciated. Thanks.

  • "0x80004005: Unspecified error" when renaming folders in Windows 7

    - by Michael Steele
    Setup I've just installed Windows 7 Ultimate 64bit. The operating system is installed on an 80GB Intel X-25M. I have a secondary 500GB Barracuda 7200.12 to be used for storage. This second drive is mounted as 'G'. Problem I'm getting an error whenever I try to rename a folder within this drive. The error says: An unexpected error is keeping you from renaming the folder. If you continue to receive this error, you can use the error code to search for help with this problem. Error 0x80004005: Unspecified error Clicking the "Try Again" button gets past the error, and correctly renames the folder. If I create a folder and leave it's name as "New Folder", then I don't see an error. I'm also able to manipulate files however I want without seeing an error. Things I've Tried Changing permissions on the drive Reformatting the drive. I've tried using both a "Basic" and "Dynamic" partition table. Checking the drive for errors using Microsoft tools Things I've Not Yet Tried When I first installed Windows I was given a choice between three types of partitions to use. I no longer remember what the choices were or what I selected. One was a GUID partition table, one was a traditional MBR, and I can't remember the third option.

  • Exchange 2010 periodically stops responding to SMTP events with error 421 4.4.1 Connection timed out

    - by Michael Shimmins
    After some help diagnosing why Exchange 2010 Enterprise stops responding to SMTP events. I can't find a pattern to it. It doesn't appear to be an actual timeout, as the server responds immediately with the error. To reproduce it I telnet into the server on port 25 and issue a EHLO. The server immediately replies with the 421: 421 4.4.1 Connection timed out Once this starts happening I've found restarting the exchange box is the only reliable way to get it flowing again. Sometimes restarting the Transport service or the mailbox attendant service seems to fix it, but this could be coincidental as it often has no effect.

  • Exchange 2010 add mailbox server to DAG error

    - by Michael
    Hello, i'm having some problems when adding a second mailbox server to my DAG in Exchange 2010. The test setup goes like this: 1x windows server 2008 (DC/DNS) 2x windows server 2008 (Exchange 2010) I have made sure all services are up and running and that the "Exchange Trusted Subsystem" account is set as a local admin. When i create a DAG i can add the first mailbox server (A) without any problems, but when i go to add the second (B) it gives me an error saying "Unable to contact the Cluster service on 1 other members (member) of the Database availability group. It does the same if i add (B) first and then try to add (A). Here is a part of the log file: [2010-04-05T15:00:27] GetRemoteCluster() for the mailbox server failed with exception = An Active Manager operation failed.

  • HyperV on Domain Controller or DC on HyperV?

    - by Michael Stum
    I want to setup a little fileserver/domain controller/sharepoint server. SharePoint shouldn't run on the DC directly, so I want to use HyperV. But I never used it before, so I wonder: Should I install the Domain Controller and HyperV Role and run 1 VM for SharePoint? Or should I run HyperV server and then 2 servers, one for SharePoint and 1 for DC? Usage is minimal with only 1 user. Hardware will be an Athlon II X3 with 3x2.9 GHz and 4 GB RAM. Operating System will be Server 2008 R2 Standard in all cases.

  • How to configure fastcgi to work with ligttpd in ubuntu

  • Copy all files and folders excluding subversion files and folders on OS X

    - by Michael Prescott
    I'm trying to copy all files and folders from one directory to another, but exclude certain files. Specifically, I want to exclude subversion files and folders. However, I'd like a general yet concise solution. I imagine I'll find the need to exclude several types of files in the near future. For example, I might want to exclude .svn, *.bak, and *.prj. Here is what I've put together so for, but it is not working for me. The first part, find works, but I'm doing something wrong with xargs and cp. I tried cp with and without the -R. Also, I'm using OS X and it appears to have a less featured version of xargs than linux systems. find ./sourcedirectory -not \( -name .svn -a -prune \) | xargs -IFILES cp -R FILES ./destinationdirectory

  • How to Configure Windows Machine to Allow File Sharing with DNS Alias

    - by Michael Ferrante
    I have not seen a single article posted anywhere online that brings together all the settings one would need to do to make this work properly on Windows, so I thought I would post it here. To facilitate failover schemes, a common technique is to use DNS CNAME records (DNS Aliases) for different machine roles. Then instead of changing the Windows computername of the actual machine name, one can switch a DNS record to point to a new host. This can work on Microsoft Windows machines, but to make it work with file sharing the following configuration steps need to be taken. Outline The Problem The Solution Allowing other machines to use filesharing via the DNS Alias (DisableStrictNameChecking) Allowing server machine to use filesharing with itself via the DNS Alias (BackConnectionHostNames) Providing browse capabilities for multiple NetBIOS names (OptionalNames) Register the Kerberos service principal names (SPNs) for other Windows functions like Printing (setspn) References 1. The Problem On Windows machines, file sharing can work via the computer name, with or without full qualification, or by the IP Address. By default, however, filesharing will not work with arbitrary DNS aliases. To enable filesharing and other Windows services to work with DNS aliases, you must make registry changes as detailed below and reboot the machine. 2. The Solution Allowing other machines to use filesharing via the DNS Alias (DisableStrictNameChecking) This change alone will allow other machines on the network to connect to the machine using any arbitrary hostname. (However this change will not allow a machine to connect to itself via a hostname, see BackConnectionHostNames below). Edit the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters and add a value DisableStrictNameChecking of type DWORD set to 1. Allowing server machine to use filesharing with itself via the DNS Alias (BackConnectionHostNames) This change is necessary for a DNS alias to work with filesharing from a machine to find itself. This creates the Local Security Authority host names that can be referenced in an NTLM authentication request. To do this, follow these steps for all the nodes on the client computer: To the registry subkey HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0, add new Multi-String Value BackConnectionHostNames In the Value data box, type the CNAME or the DNS alias, that is used for the local shares on the computer, and then click OK. Note: Type each host name on a separate line. Providing browse capabilities for multiple NetBIOS names (OptionalNames) Allows ability to see the network alias in the network browse list. Edit the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters and add a value OptionalNames of type Multi-String Add in a newline delimited list of names that should be registered under the NetBIOS browse entries Names should match NetBIOS conventions (i.e. not FQDN, just hostname) Register the Kerberos service principal names (SPNs) for other Windows functions like Printing (setspn) NOTE: Should not need to do this for basic functions to work, documented here for completeness. We had one situation in which the DNS alias was not working because there was an old SPN record interfering, so if other steps aren't working check if there are any stray SPN records. You must register the Kerberos service principal names (SPNs), the host name, and the fully-qualified domain name (FQDN) for all the new DNS alias (CNAME) records. If you do not do this, a Kerberos ticket request for a DNS alias (CNAME) record may fail and return the error code KDC_ERR_S_SPRINCIPAL_UNKNOWN. To view the Kerberos SPNs for the new DNS alias records, use the Setspn command-line tool (setspn.exe). The Setspn tool is included in Windows Server 2003 Support Tools. You can install Windows Server 2003 Support Tools from the Support\Tools folder of the Windows Server 2003 startup disk. How to use the tool to list all records for a computername: setspn -L computername To register the SPN for the DNS alias (CNAME) records, use the Setspn tool with the following syntax: setspn -A host/your_ALIAS_name computername setspn -A host/your_ALIAS_name.company.com computername 3.
