Unable to connect: Adaptive Server is unavailable or does not exist

Everything I have found points to freetds:

http://stackoverflow.com/questions/2299 ... -not-exist
http://stackoverflow.com/questions/1639 ... -not-exist
http://stackoverflow.com/questions/8511 ... -sql-serve

Same version, but are the configs the same?

These seem to point to creating a separate configuration requiring modification of SQL on the client???

From this page here:

Try running the tsql command by itself:
Then attach the /tmp/freetds.log file so that we can review.
