How-to : Installing ESXi 5 on VMware Workstation 9

How-to : Use SQL Server to query Active Directory

-

I think it’s common problem as Active Directory gets bigger in organizations, control over content of that mission-critical component seems to be lost. Same happened in my place. In addition to that we had to provide information from AD on a regular basis in a form of report. We had no tools to pull all data from AD, process it and present in some readable format. However, I was working with skilled SQL guy who was also very good in Reporting Services. So, I proposed that we can link Active Directory with SQL Server and use Transact-SQL to pull information from AD, process it on SQL and then make it readable and presentable through Reporting Services. That would allow SQL guy to process all information and do all kind of reporting required.

Here are components of our LAB environment before solution went to production:

And below steps how we made SQL Server 2008 R2 to work with Active Directory to use Transact-SQL queries to pull information from directory database.

Again one of those things which I forget when is needed. Autologon in Windows XP. Funny enough is the fact that each time I’m looking for this information is when I want to prevent Windows XP from auto logon and trying to disable that in registry using remote access from Registry Editor.

Fortunately Microsoft prepared full detailed description, so now I can write down in my scratchpad for future reference instead of using Google each time I need that 😀

Tips & Tricks : Session log files in SecureCRT

-

I use SecureCRT quite often to access Linux systems as well as network devices.

When going through one of the presentations on SecureCRT web page I found handy tip how to configure session logs to have it divided by date, time and session.

Screenshot below demonstrates settings for log file:

SecureCRT Log File configuration

Basically parameters are set to:

  • Log file name: %Y-%M-%D–%h-%m-%s.%t__%S(%H).txt
  • Options / Start log upon connect: checked
  • Custom log data / On each line: %h:%m:%s(%t):

These settings will create separate log file for each session every time connection will be established.

In addition to that each line will start with timestamp added by SecureCRT.
