FreeTDS working, but ODBC cannot connect
Solution 1
The issue was this line in odbc.ini
[database3] must be [dbs3] in your case.
For those that are also having this problem, Check also the
ServerName = *Points to the name of the server configured in freetds.conf*
Solution 2
If odbc does not find the datasource it means you are providing the wrong one
You are probably trying to connect to dbs3
which will fail if you don't have it in odbc.ini
You should connect to [database3]
for ODBC
isql -v database3 <username> <password>
Solution 3
I had the same problem, I found out that you have to execute the following after each modification of odbc.ini
:
odbcinst -i -s -f /etc/odbc.ini
After that, tested this :
isql -v SERVER USER PWD
and I got this output:
+---------------------------------------+
| Connected! |

| sql-statement |
| help [tablename] |
| quit |

I am trying to run connect to a MSSQL server from an Ubuntu 12.04 webserver with FreeTDS and unixODBC.
Using tsql i can connect to the server with
~$ tsql -S dbs3 -U <username> -P <password>
No problem there.
When I try to connect with isql however, I get the following error message:
~$ isql -v database3 <username> <password> [S1000][unixODBC][FreeTDS][SQL Server]Unable to connect to data source [01000][unixODBC][FreeTDS][SQL Server]Unknown host machine name. [ISQL]ERROR: Could not SQLConnect
My config files are as follows:
odbc.ini
[database3] Driver=FreeTDS TDS_Version=8.0 Servername=dbs3 Port=1433 Database=benchmark_res
odbcinst.ini

I followed the installation guide 1. here and 2. here
Why isn't isql connecting properly?
My guess is that the mistake is super obvious but I'm just too stupid to see it :D -
AndMim over 10 yearsThat's what I am doing. I use dbs3 with tsql: tsql -S dbs3 -U <username> -P <username>. Using isql the way you mentiones returns these errors

meda over 10 yearsOk have you added database3 to your host file
-
AndMim over 10 yearsNo, because from my understanding, it should be resolved with the IP I entered in the freetds.conf
-
meda over 10 yearsboth freetds and odbc

AndMim over 10 yearsODBC:
sudo apt-get install unixodbc-dev unixodbc-bin unixodbc
freeTDS: I built that from source. I linked the description I followed in the original question -
