I get the following error when trying to connect Splunk db connect 3.1 on Linux to on a Windows machine
Database connection xxxx is invalid.
The TCP/IP connection to the host hostname, port 1433 has failed. Error: "null. Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. Make sure that TCP connections to the port are not blocked by a firewall.".
Can you telnet to the SQL server on port 1433 from the server that is running db connect? If not, check your network firewall or host firewalls.
