«Неизвестное имя хост-машины». на FreeBSD + unixODBC + FreeTDS

У меня возникли проблемы с подключением к Microsoft SQL Server 2012 с моего сервера FreeBSD 10.1.

Установил FreeTDS и unixODBC через порты. Я скомпилировал FreeTDS с поддержкой unixODBC. Это мой freetds.conf:

[server1]
  host = 192.168.100.147
  port = 1433
  tds version = 7.2

Вызов tsql работает нормально.

Но когда я пытаюсь подключиться через odbc с «osql» или «isql», соединение прерывается со следующей ошибкой:

    trying /tOH ... no

Configuration looks OK.  Connection details:

                   DSN:    server1
              odbc.ini:    /usr/local/etc/odbc.ini
                Driver:    /usr/local/lib/libtdsodbc.so
       Server hostname:    sqlsrv01
               Address:    192.168.100.147

[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

Это содержимое моего odbc.ini:

[server1]
  Driver = FreeTDS
  Servername = server1

А это мой odbcinst.ini:

[FreeTDS]
  Driver = /usr/local/lib/libtdsodbc.so
  Client Charset = UTF-8
  UsageCount = 1

Я читал серьезные сообщения об использовании точного именования inf odbc.ini и freetds.conf, но соединение продолжает разорваться.

Кто-нибудь может помочь?
