I need an easy and complete tutorial for making a MSSQL connection from Ubuntu.

I think I installed FreeTDS and UnixODBC but configurations are very complicated I didn't understand the issue.

I followed this tutorial: <https://github.com/rails-sqlserver/activerecord-sqlserver-adapter/wiki/Platform-Installation---Ubuntu>

But I failed.

```
root@hackmachine:~# isql -v example.com XXXXX XXXXXXX
[IM002][unixODBC][Driver Manager]Data source name not found, and no default driver specified
[ISQL]ERROR: Could not SQLConnect
root@hackmachine:~# 

```

Edit:

Before this edit "/etc/odbcinst.ini" and "/etc/odbc.ini" was empty. 

I added these lines to /etc/odbcinst.ini :

```
[FreeTDS]

Description     = TDS driver (Sybase/MS SQL)

Driver = /usr/lib/x86_64-linux-gnu/odbc/libtdsodbc.so

Setup = /usr/lib/x86_64-linux-gnu/odbc/libtdsS.so

CPTimeout       =

CPReuse         =

FileUsage       = 1

```

I added these lines to /etc/odbc.ini :

```
[project_development]
Driver = FreeTDS
Description     = ODBC connection via FreeTDS
Trace           = No
Servername      = developer
Database        = project_development

[project_test]
Driver = FreeTDS
Description = ODBC connection via FreeTDS
Trace = No
Servername = developer
Database = test

[project_production]
Driver = FreeTDS
Description = ODBC connection via FreeTDS
Trace = No
Servername = production
Database = project_production

```

I didn't make any changes on "/etc/freetds/freetds.conf" since the very beginning.

Still, nothing has changed.
