He configurado FreeTDS para conectarme a la base de datos de SQL Server. Cuando intento abrir TSQL en la terminal en Mac (león) me sale este error:

locale is "en_US.UTF-8"
locale charset is "UTF-8"
using default charset "UTF-8"
Error 20017 (severity 9):
    Unexpected EOF from the server
    OS error 36, "Operation now in progress"
Error 20002 (severity 9):
    Adaptive Server connection failed
There was a problem connecting to the server

Alguien tiene idea de lo que podría estar causando esto?
