Test an SQL Server Connection

I found myself working on a ASP.NET MVC application that was backed by a SQL Server database.  Now the team over in the office can connect to it fine.  However, as mentioned previously, I am working from home until the new office in Winchester opens.  The server was an Amazon RDS instance and I bet that it only allowed white-listed networks to connect to it.  (My speciousness was due to an error reported by Entity Framework as ‘The underlying provider failed’)

So I needed to test it quick, and only test the connection and nothing else.  So I saw this on msdn and created an empty ‘.txt’ file and renamed it with the ‘.udl’ (Universal Data Link) extension.  Then I put in my connections strings and hit ‘Test Connection.’


Sure enough, I got an access denied error.  So I called the person responsible for managing that instance, gave them my I.P. address and I was off to the races.

Good thing to keep in your head.

Turn off ‘bell’ or ‘ding’ in Terminal

If you are using bash:

  1. Edit or create a .inputrc file in your $HOME direcotry
    • vim $HOME/.inputrc  (for vim users, can substitute gedit for ‘vim’
  2. Append the following line:
    • “set bell-style none” (without the “”)


If you are using ‘Terminal’ on Mac OSX see this stackoverflow question.

(To paraphrase: “With Terminal open, go to ‘Terminal’ > ‘Perferences…’, the click the ‘Profiles’ tab,  then go to ‘Advanced’ and there is a ‘Bell’ subsection where you can uncheck “Audible Bell.”)
