OK, this is good.  we know *something* is listening to 1433 on ntdevmog451
and we're willing to believe it's SQL Server.

The problem here is your freetds.conf entry:

You don't need instance and port; choose one.   The instance is the name
of the port (basically), and in reading freetds.conf instance supersedes
port.  

My guess is there's no *instance* named 'ntdevmog451'; the client queries
for it, the server says there is none, and the client tries to use port 0.
 If you comment out the instance name (or use the right one) I bet it will
work.

I suspect your tsql commands are failing because the compiled-in default
TDS version is 5.0.  "tsql -C" will confirm that.  If so:

$ TDSVER=8.0 tsql -H ntdevmog451 -p 1433 -U allzse -P allzse

should work and 

$ TDSVER=8.0 tsql -H ntdevmog451 -p 1433 -U allzse -P allzse -L 

(using a recent snapshot) will return a list of instance names and their
ports.  

HTH.
