Check for SQL server port mismatch Re: tsql -S works but tsql -H times out

Thanks Eric--

Someone had turned on dynamic ports on the SQL server and didn't set it back so instead of having the server listening at 1433 like I thought. 

tsql -LH 123.123.123.123 showed the portnumber to be up in the 49000 range.

tsql -H 123.123.123.123\\instancename -p portnumber -U 

Things worked when instead of using 1433, I set it to the right number.
my freetds.conf 
only had

[shortname]
  host = 123.123.123.123
  instance = instance
  tds version = 8.0

and didn't have a port =  
in it. 

Am guessing that 
tsql -S shortname -U sa 
was talking to the SQL Server Browser which sent things to the correct dynamic port


For what it's worth
TDSVER=7.2 tsql -H 123.123.123.123\\instancename -p portnum -U username
on SQL Server 2008 Express 
will connect but first throws up the following error 
Error 100 (severity 11):
              unrecognized msgno

Changing to
TDSVER=8.0 
fixes that.
