Connect to Windows Share from Ubuntu

When I attempted to connect to Windows Share from Ubuntu 12.04, I got this error message: "Failed to retrieve share list from server"

Found solution from UbuntuForums.org (http://ubuntuforums.org/showthread.php?t=1082148&page=12&p=9762937#post9762937). Enter "smb://192.168.123.123" where 192.168.123.123 is the IP address of Windows Share, it bring up the list of shared folders on Windows machine.

Now, I just entered the user name and password to get in.

Using ODBC 32-bit on 64-bit Operating System

Which ODBC driver should we install on 64-bit machine using Windows Server 2008 R2, Windows Server 2012, Windows 7, or Windows 8? It would depend. When I installed MySQL ODBC 64-bit driver on Windows 8.1 Preview, it worked when I added a new DSN. But, it did not work when Microsoft Access 2007 application made ODBC call to MySQL server.

What wrong? It took me couple hours to figure out. Microsoft Access 2007 may not work with other 64-bit driver or program yet. Installed MySQL ODBC 32-bit solve the problem.

On Windows 8.1, there are two ODBC Administrors under Control Panel – Administrative Tools. One for ODBC Datasources 32-bit and one for ODBC Datasources 64-bit. On Windows Server 2008 R2, there is only one reference to ODBC Administrator. This is 64-bit. Where is 32-bit? To add or manage DSN for ODBC 32-bit, you need to call program odbcad32.exe in C:\Windows\SysWOW64\

Hope this help.

How to access Wamp Server running on Windows 2008 from other computer?

The firewall rules on Windows 7 or Windows 2008 or later version may not allow you access to your web site running by WampServer from other computer. To fix this problem:

Step 1: Update httpd.conf to add this line
Allow from 192.168.1.0/255.255.255.0 # for LAN
#or
Allow from all # for any computer in the world
Remember to restart Apache server after change the httpd.conf

Step 2: Check Windows Firewall.

• Is the port 80 open?
• Is the Apache Web Server (\wamp\bin\apache\Apache2.4.4\bin\httpd.exe allow to receive the request from other?

WAMP

WAMP stands for Microsoft Windows operating system, Apache web server, MySQL database, and PHP general-purpose scripting language for server side Web development. Among WAMP server packages, I like WampServer since it easy to instal, have latest version from Apache, MySQL and PHP and it's free. Before you install the WampServer, you need to make sure your computer have:

• Microsoft Visual C++ 2010 run-time. Without Microsoft Visual C++ 2010 run-time, you will see the error message "vcr100.dll missing" when install.
• Microsoft .NET Framework 3.5.1. This fixed the problem 'aestan tray menu has stopped' when you start the WampServer

To install Microsoft Visual C++ 2010 Redistributable Package (x64) ( http://www.microsoft.com/en-us/download/details.aspx?id=14632 )

On Windows 2008R2 server, make sure .NET Framework 3.5.1 enable. It disable by default. ( http://social.technet.microsoft.com/Forums/windowsserver/en-US/ac1bf719-0a88-4b5d-be98-395f2623e805/what-version-of-net-framework-comes-with-windows-2008-r2 )
