[Paul Wuersig <pwuersig AT nvidia.com>]

I've also set up iODBC and added the FreeTDS and server information to
odbc.ini and odbcinst.ini.

Running a python script that uses pyodbc yields the error:
pyodbc.Error: ('00000', '[00000] [iODBC][Driver Manager]dlopen({SQL
Server}, 6): image not found (0) (SQLDriverConnect)')


[Frediano]

Did you enable OpenSSL or GnuTLS?


[Paul]

No, I didn't realize those were potentially necessary. Is there a way to
query the DB to find out?

[Randy]

<turn on logging!>

[Paul]

$ TDSDUMP=/tmp/freetds.log tsql -H hqnvogl02 -p 1433 -U restuser
locale is "en_US.UTF-8"
locale charset is "UTF-8"
Password: 
Msg 20017, Level 9, State -1, Server OpenClient, Line -1
Unexpected EOF from the server
Msg 20002, Level 9, State -1, Server OpenClient, Line -1
Adaptive Server connection failed
There was a problem connecting to the server

--

The salient part of the log is, I believe:
token.c:312:tds_process_login_tokens()
util.c:334:tdserror(0x7fe251400b10, 0x7fe251401170, 20017, 36)
util.c:368:tdserror: client library returned TDS_INT_CANCEL(2)


Thanks,
Paul
