I am trying to use FreeTDS to connect from a Linux server (RHEL v7) to a separate server running MS SQL Server 2014. However, when attempting to connect with tsql I get the following errors (error message differs depending on whether I include username and password):
$ tsql -S MYSERVER locale is "en_US.UTF-8" locale charset is "UTF-8" using default charset "UTF-8" Error 20002 (severity 9): Adaptive Server connection failed There was a problem connecting to the server $ tsql -S MYSERVER -U myusername -P mypassword locale is "en_US.UTF-8" locale charset is "UTF-8" using default charset "UTF-8" Error 20017 (severity 9): Unexpected EOF from the server Error 20002 (severity 9): Adaptive Server connection failed There was a problem connecting to the server
Additionally, running tsql -LH gives no output:
$ tsql -LH MYSERVER $
I don't believe the issue is with a firewall or anything else on the SQL Server side, because:
I am able to telnet to the server:
$ telnet my.server.address 1433 Trying 18.104.22.1684... Connected to my.server.address.
- And, I can successfully connect to the SQL Server via ODBC from a (Windows) laptop, via the ODBC Data Source Administrator utility.
Contents of my /etc/freetds.conf:
[global] tds version = 7.0 ; tds version = 4.2 ... [MYSERVER] host = my.server.address port = 1433 tds version = 7.0
