• One user sometimes gets an unknown certificate error opening Outlook

  - by Chris

  Let me clarify a little. This isn't an unknown certificate error it's an unknown certificate error in so much as I can't figure out where the certificate comes from. This happens on a Win 7 Enterprise machine connecting to Exchange 2010 with Outlook 2010. The error he gets is that the root is not trusted because it's a self-signed cert. Take a look at this screenshot because even if I had generated this myself I wouldn't have put "SomeOrganizationalUnit" or "SomeCity" or "SomeState", etc. (Red block covers our domain name.) I'm a little concerned this is a symptom of a security breach. Exchange 2010 has three certificates installed but none of them are this certificate. They all have different expiration dates (one is expired) and different meta-data. edit: There are two scenarios that I see the certificate warning and one of them I can reliably repeat. When the user leaves his computer on over night Outlook pops the Security Warning window. I don't know what time this happens. Using Outlook Anywhere if I connect to Exchange externally via a cellular USB modem the Security Warning window will appear every time I close and reopen Outlook. Whether I say Yes or No does not make a difference on whether or not I can connect to Exchange and send/receive email. In other words, I can always connect to Exchange. I've checked my two Exchange servers and my Cisco router for a certificate that matches this one and I can't find it. edit 2: Here is a screenshot of the Security Alert window. (I've been calling it Security Warning... My mistake.) edit 3: I stopped seeing this error several weeks ago but I can't tie it to any single event (because I just sort of realized that warning had stopped showing up) but I think I found the source of the certificate. Last week I found out that the certificate on our website DomainA.com was invalid. I knew that our web admin had installed a valid certificate so when I look into the problem I found out I was being presented with the invalid certificate that this posting is in regards to. The Exchange server's domain is mail.DomainA.com so I can only guess that Outlook was passing this invalid certificate through as it did some kind of check on DomainA.com. This issue is still a mystery because the certificate warning stopped appearing several weeks ago whereas the invalid certificate issue on the website was only fixed last week. It ended up being a problem with the website control panel. The valid certificate was installed but not being served for some reason and instead the self-signed cert was being served.

• How to sanitize log messages in Log4j to save them in database

  - by Rafael

  Hello, I'm trying to save log messages to a central database. In order to do this, I configured the following Appender in log4j's xml configuration: <appender name="DB" class="org.apache.log4j.jdbc.JDBCAppender"> <param name="URL" value="jdbc:postgresql://localhost/logging_test" /> <param name="user" value="test_user" /> <param name="password" value="test_password" /> <param name="sql" value="INSERT INTO log_messages ( log_level, message, log_date ) VALUES ( '%p', '%m', '%d{yyyy-MM-dd HH:mm:ss}' )" /> </appender> This works fine, except some of the messages contain ', and then the appender fails. Is there an easy way to do this?

• Handling Messages in Console Apps/DLLs in C++ Win32

  - by vsimon

  I would like to have the ability to process Win32 messages in a console app and/or inside a standalone DLL. I have been able to do it in .NET with the following article and it works great in C# inside a console app and standalone DLL http://msdn.microsoft.com/en-us/magazine/cc163417.aspx Is there a way to do the equivalent with C/C++ Win32 APIs? I have tried doing RegisterClassEx(...) and CreateWindow(...) even passing in HWND_MESSAGE to hWndParent but the trouble is that after the "invisible" window is created messages are not being processed probably due to the lack of a message pump. Where would the message pump go if you had a DLL entry point? I have tried creating another thread in a DLL and put while(GetMesage(..)) there but that did not work either. Any ideas?

• Getting meaningful error messages from fstream's in C++

  - by Hassan Syed

  What is the best way to get meaningful file access error messages, in a portable way from std::fstreams ? The primitiveness of badbits and failbits is getting to be bit annoying. I have written my own exception hierarchies against win32 and POSIX before, and that was far more flexible than the way the STL does it. I am getting "basic::ios_clear" as an error message from the what method of a downcasted catch (std::exception) of a fstream which has exceptions enabled. This doesn't mean much to me, although I do know what the problem is I'd like my program to be a tad more informative so that when I start deployment a few months later my life will be easier. Is there anything in Boost to extract meaningful messages out of the ofstream's implementation cross platform and cross STL implementation ?

• Returning messages in Smalltalk

  - by Zachary

  I have a Dictionary of objects I have created in smalltalk, which I am iterating over by enumerating it based on the key/value pairs. For value object in the dictionary, I am calling a method on that object. Based on certain conditions, I would like for this object to be able to add a new member to dictionary, and possibly delete another one. I've been looking at the 'Perform' and 'Messages' facilities in Smalltalk, but I'm not sure if it is even possible to do what I'm trying to do - is it possible to return a message (or multiple messages), which another object can process and perform? For example, could my method return 'removeKey: 19' and 'add object' at the same time? I am using GNU Smalltalk, if it matters.

• Django - Check users messages every request

  - by Hanpan

  Hi, I want to check if a user has any new messages each time they load the page. Up until now, I have been doing this inside of my views but it's getting fairly hard to maintain since I have a fair number of views now. I assume this is the kind of thing middleware is good for, a check that will happen every single page load. What I need it to do is so: Check if the user is logged in If they are, check if they have any messages Store the result so I can reference the information in my templates Has anyone ever had to write any middleware like this? I've never used middleware before so any help would be greatly appreciated.

• Outlook 2010 says "File is in use by another application or user" while closing

  - by A_Pointar

  Outlook opens, gets new emails and everything but when I close it, it gives me the following error and then opens up a Save a File window after I cancel this error message. There's no other computer that may be using Outlook under this User Name because I just set-up a brand new User Name. However, Colligo Briefcase is attached to the Outlook and not sure if this is triggering and if so how I address the issue!? Thanks a lot!

• How do I create Ntlm Type 1 and Type 3 messages in .Net

  - by brj011

  I need to create Type 1 message and Type 3 message for NTLM handshaking. Is there any .Net API for this? Essentially, the application is WPF based, but Socket is used in order to stream data from the server. Use of socket is a technical requirement, but the problem is when user needs to connect to the server using a proxy server. Further, if the proxy authorization is based on Ntlm, the client application needs to create Type 1 and Type 3 messages in order to handshake with the proxy server. My question is: Is there any API already available in .NET libraries that can be consumed in order to create these different types of NTLM messages? Any help or alternatives will be greatly appreciated. Thanks in advance.

• Make all changes by a user reversible on linux

  - by Darokthar

  Is it possible to safe all changes a user does in his home directory? The idea is to be able to recover a home directory if a file is deleted or overwritten. My problem is having an old family member (80+ years) who wants to learn how to use a computer. For me it would be easier to recover the home directory from any abuse or mistakes that the user might do. Is there an easy solution, which is quite failsafe?

• Viewing directory containing MIME encoded email messages

  - by Mark

  I have an application which generates and sends MIME encoded messages (javax.mail.internet.MimeMessage) through an SMTP server. As part of the development process only, I'd like to be able to view these messages rather than send them (I know the sending works just fine, but there are restrictions on the domains within the dev environment which makes it a little difficult) I thought the easiest way would be to save the text for each message to a directory, then point "an app" at the directory and check them over. So the question is, what would be a good app to use? Is it as simple as configuring Outlook or another email client to do it? Thanks

  How can you run an application as another user in Windows 7? The only catch is that I don't want to have to hold down the shift key, right click on the application and choose Run as different user. I need it to automatically login using the login credentials I specify.

  - by user332172

  How to delete duplicate restored user files with "(2)" added (Win7) I restored my user files on windows 7 system from the Win 7 backup. I selected the wrong restore option and all files were restored. Existing unchanged files were restored with the text string " (2)". Is there a way to write a batchfile or script to do this operation? Example file name: "01 lesson 1" "01 lesson 1 (2)" I want to delete all files which had " (2)" appended on restore.

• Windows 7 - User-specific %PATH%

  - by MiffTheFox

  I'd like to set up a system for Windows 7 where each user has their own private directory in %PATH%. I tried setting %PATH% to %HOMEDRIVE%%HOMEPATH%\Bin;%SystemRoot%\System32;[...] but it doesn't seem to work. For those who don't realize what I'm trying to do, it's sort of like EXPORT PATH=~/bin would be on *nix. It can be on a user specific basis if need be (and that would actually be prefer to the machine-wide settings).

• How to Write to a User.Config file through ConfigurationManager?

  - by Josh G

  I'm trying to persist user settings to a configuration file using ConfigurationManager. I want to scope these settings to the user only, because application changes can't be saved on Vista/Win 7 without admin privileges. This seems to get me the user's configuration, which appears to be saved here in Win 7 ([Drive]:\Users\[Username]\AppData\Local\[ApplicationName]\[AssemblyName][hash]\[Version\) Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.PerUserRoamingAndLocal); Whenever I try to save any changes at all to this config I get this exception: InnerException: System.InvalidOperationException Message="ConfigurationSection properties cannot be edited when locked." Source="System.Configuration" StackTrace: at System.Configuration.SectionInformation.VerifyIsEditable() at System.Configuration.MgmtConfigurationRecord.GetConfigDefinitionUpdates(Boolean requireUpdates, ConfigurationSaveMode saveMode, Boolean forceSaveAll, ConfigDefinitionUpdates& definitionUpdates, ArrayList& configSourceUpdates) I have tried adding a custom ConfigurationSection to this config. I have tried adding to the AppSettingsSection. Whenever I call config.Save() it throws the exception above. Any ideas? I tried using the ApplicationSettingsBase class through the Project-Settings designer, but it doesn't appear that you can save custom types with this. I want similar functionality with the ability to save custom types. Thanks.

• How do I run a command as a different user from a root cronjob?

  - by rob

  I seem to be stuck between an NFS limitation and a Cron limitation. So I've got root cron (on RHEL5) running a shell script that, among other things, needs to rsync some files over an NFS mount. And the files on the NFS mount are owned by the apache user with mode 700, so only the apache user can run the rsync command -- running as root yields a permission error (NFS being a rare case, apparently, where the root user is not all-powerful?) When I just want to run the rsync by hand, I can use "sudo -u apache rsync ..." But sudo no workie in cron -- it says "sudo: sorry, you must have a tty to run sudo". I don't want to run the whole script as apache (i.e. from apache's crontab) because other parts of the script do require root -- it's just that one command that needs to run as apache. And I would really prefer not to change the mode on the files, as that will involve significant changes to other applications. There's gotta be a way to accomplish "sudo -u apache" from cron?? thanks! rob

• Is it wrong for a context (right click) menu be the only way a user can perform a certain task?

  - by Eric

  I'd like to know if it ever makes sense to provide some functionality in a piece of software that is only available to the user through a context (right click) menu. It seems that in most software I've worked with the right click menu is always used as a quick way to get to features that are otherwise available from other buttons or menus. Below is a screen shot of the UI I'm developing. The tree view on the right shows the user's library of catalogs. Users can create new catalogs, or add and remove existing catalogs to and from their library. Catalogs in their library can then be opened or closed, or set to read-only. The screen shot shows the context menu I've created for the browser. Some commands can be executed independently from any specific catalog (New, Add). Yet the other commands must be applied to a specifically selected catalog (Close, Open, Remove, ReadOnly, Refresh, Clean UP, Rename). Currently the "Catalog" menu at the top of the window looks identical to this context menu. Yet I think this may be confusing to the users as the tree view which shows the currently selected catalog may not always be visible. The user may have switched to the Search or Filters tab, or the left pane may be hidden entirely. However, I'm hesitant to change the UI so that the commands that depends on a specifically selected catalog are only available through the context menu.

• VSS error 521 when attempting backup

  - by blade

  Hi, I have backupassist and I attempt to run a backup, with VSS service running. However, I get this error in Windows Event Log: The backup operation that started at '?2010?-?04?-?30T01:51:15.601000000Z' has failed because the Volume Shadow Copy Service operation to create a shadow copy of the volumes being backed up failed with following error code '2155348129'. Please review the event details for a solution, and then rerun the backup operation once the issue is resolved. Code: 521. The error in backupassist is: The backup operation stopped before completing. Detailed error: ERROR - A Volume Shadow Copy Service operation error has occurred: (0x80042336) The writer experienced a partial failure. Check the component level error state for more information.

Check the component level error state for more information. Any idea how to fix this? I work in a company with server engineers, they all state of having no problems with 2008 and VSS (though in the company we use predominantly 2003). Without vss working, I assume no backup application will work? Thanks

• error: a NUL byte in commit log message not allowed [migrated]

  - by James

  I'm trying to commit some files in my Git repository, and I'm receiving this error. This all started when I ran git rm -rf folder and git rm -rf file and tried to commit the changes. I've since been able to commit and push without these files being deleted from my remote repository, however I'm now completely stuck. The full error is: error: a NUL byte in commit log message not allowed. fatal: failed to write commit object What can I do to fix this? My Google-fu has let me down on this one. Edit: I've just checked out these deleted files, and attempted to commit again, but it's still giving me the same error. Has my Git repo been corrupted or something?

• Retrieve user details from Active Directory using SID

  Hi, How can I find a user in my AD when I have his/her SID. I don't want to rely on other attributes, since I am trying to detect changes to these. Example: I get a message about a change to user record containing: Message: User Account Changed: Target Account Name: test12 Target Domain: DOMAIN Target Account ID: %{S-1-5-21-3968247570-3627839482-368725868-1110} Caller User Name: Administrator Caller Domain: DOMAIN Caller Logon ID: (0x0,0x62AB1) Privileges: - I want to notify the user about the change. So I need their account-information from AD. When I try to retrieve the user's data from AD via VBScript like this: Wscript.StdOut.writeLine "Found an Account ID: " & objMatch.value Set objUser = GetObject("LDAP://GUID=1521396824757036278394823687258681110") Wscript.StdOut.writeLine objUser I receive an error stating The handle is invalid Code:80070006

• Configuring external SMTP server on Azure VM - messages staying in queue

  I have an external SMTP provider: auth.smtp.1and1.co.uk I am trying to send SQL Server Reporting Services emails via this on an Windows 2012 Azure VM.
