Here is some more fodder. I turned on tracing in the driver code:

cs_ctx_alloc(CS_VERSION_100, &ctx) -> CS_SUCCEED, ctx0
cs_diag(ctx0, CS_INIT, CS_UNUSED, CS_UNUSED, NULL) -> CS_SUCCEED
ct_init(ctx0, CS_VERSION_100) -> CS_SUCCEED
ct_config(ctx0, CS_SET, CS_NETIO, 29, CS_UNUSED, NULL) -> CS_SUCCEED
ct_con_alloc(ctx0, &conn) -> CS_SUCCEED, conn0
ct_diag(conn0, CS_INIT, CS_UNUSED, CS_UNUSED, NULL) -> CS_SUCCEED
ct_con_props(conn0, CS_SET, CS_USERNAME, "XXX", CS_NULLTERM, NULL) -> 
CS_SUCCEED
ct_con_props(conn0, CS_SET, CS_PASSWORD, "YYY", CS_NULLTERM, NULL) -> 
CS_SUCCEED
ct_connect(conn0, "mydb", CS_NULLTERM) -> CS_FAIL
ct_diag(conn0, CS_STATUS, CS_SERVERMSG_TYPE, CS_UNUSED, &num) -> CS_SUCCEED, 0
ct_diag(conn0, CS_STATUS, CS_CLIENTMSG_TYPE, CS_UNUSED, &num) -> CS_SUCCEED, 0
ct_diag(conn0, CS_CLEAR, CS_ALLMSG_TYPE, CS_UNUSED, NULL) -> CS_SUCCEED
ct_con_props(conn0, CS_GET, CS_CON_STATUS, &value, CS_UNUSED, NULL) -> 
CS_SUCCEED, 0
ct_diag(conn0, CS_STATUS, CS_SERVERMSG_TYPE, CS_UNUSED, &num) -> CS_SUCCEED, 0
ct_diag(conn0, CS_STATUS, CS_CLIENTMSG_TYPE, CS_UNUSED, &num) -> CS_SUCCEED, 0
ct_diag(conn0, CS_CLEAR, CS_ALLMSG_TYPE, CS_UNUSED, NULL) -> CS_SUCCEED
ct_con_drop(conn0) -> CS_SUCCEED
cs_ctx_drop(ctx0) -> CS_SUCCEED

And here is the log from FreeTDS tracing:

2002-09-24 16:13:58 IP address pointer is NULL
2002-09-24 16:13:58 leaving ct_connect() returning 0
2002-09-24 16:13:58 inside ct_con_props() action = CS_GET property = 26
2002-09-24 16:13:58 inside ct_con_drop()


I suspect the big problem is that "IP address pointer is NULL". I have a
working version using mxODBC/unixODBC, and it passes the correct IP
address at the start.
