我使用FreeTDS 0.91连接到远程MSSQL服务器,但到目前为止,所有尝试都没有取得任何成果。
在我的Unix上执行tsql命令时,我会得到以下错误:
locale is "en_US.UTF-8"
locale charset is "UTF-8"
using default charset "UTF-8"
Error 20004 (severity 9)
Read from the server failed
OS error 104, "Connection reset by peer"
Error 20002 (severity 9)
Adaptive Server connection failed
There was a problem connecting to the serverfreetds.log中包含以下内容:

太迷茫了。请帮帮忙。
当我通过telnet连接到服务器时,这是我得到的响应:
尝试70.70.218.13..。
连接到70.70.218.13。
转义字符是“^]”。
^^
外部主机已关闭连接。
这是否意味着到主机的telnet连接是成功的?
SQL数据库运行在windows服务器上。连接到Windows服务器(就像通过远程桌面连接)会是主机名和端口使用的正确类型吗?或者我必须在windows服务器上找到一个直接指向SQL服务器的主机名?

可汗。
我只是遇到了同样的情况。我在家里增加了一个.freetds.conf,解决了这个问题,
[global]
# TDS protocol version
tds version = 7.0 我知道这正是大多数FreeTDS连接问题的答案。
这个方法也是由@提供的。

对于五年亡灵表示歉意,当tsql成功连接到开放端口时,似乎也会发生此错误,但侦听器是SQL Server以外的其他服务。FreeTDS似乎没有尝试在登录时检查它是否在与Server以外的服务对话,因此错误消息是神秘的。(在我的例子中,我使用了远程桌面的端口号。)

如果不想创建.freetds.conf,只需设置TDSVER环境变量(例如,在TDSVER上连接到Server 2008,使用TDS版本7.3):
set TDSVER=7.3(对于*nix使用export)。
有关更多环境变量,请参见http://www.freetds.org/userguide/envvar.htm。
有关不同RDBMS的TDS版本,请参见http://www.freetds.org/userguide/choosingtdsprotocol.htm
您还可以为日志文件指定一个路径,该路径可以通过设置环境变量TDSDUMP来提供更多信息,这将有助于解决问题并显示查找配置文件的位置。例如:
set TDSDUMP=C:\temp\freetds.log在我的例子中,设置TDSDUMP变量显示了日志中的一个错误:
iconv.c:346:setting up conversions for client charset "CP1252;LC_CTYPE=English_United States.1252;LC_MONETARY=C;LC_NUMERIC=C;LC_TIME=C"
iconv.c:348:preparing iconv for "CP1252;LC_CTYPE=English_United States.1252;LC_MONETARY=C;LC_NUMERIC=C;LC_TIME=C" <-> "UCS-2LE" conversion
iconv.c:423:tds_iconv_info_init: client charset name "-1" invalid显然,States.1252;LC_MONETARY=C;LC_NUMERIC=C;LC_TIME=C“没有解析字符串"CP1252;LC_CTYPE=English_United CP1252;LC_CTYPE=English_United”中的字符集名称
我创建了一个具有以下内容的.freetds.conf文件:
[global]
tds version = 7.3 # version 7.3 for MSSQL 2008
client charset = UTF-8 # so that we can get unicode characters并按照日志文件的建议将其保存到C:\Windows\System32\config\systemprofile\AppData\Roaming\,这为我解决了问题。
