Nedd your help to get DBD:Sybase working to connect to SQL Server (4 messages)

Dear Experts,

I am new to perl and I really need your help. I need your help for a perl
DBD:sybase module i am using.

I am trying to connect to a MS SQL Server from a linux server. Below are
the details and the error message.

Request you to let me know how I can fix it. I will provide any more logs
which you may require. For now, below are the details.

Thank you very much. Looking forward for your assistance.


Brief Description
I have freetds, DBI and DBD:Sybase installated. When i TSQL to a sql server
is works fine, but when i try to connect form a perl script it fails with
the error "REquested server name not found". by testing i have noticed it
may be using $HOME/interfaces file instead of freetds.conf file.
