Hi team,
The teradata connector works fine when we are in the same domain than the database. But we are facing an issue when there's a proxy to pass. For your information, if we put the host including its domain, it does not work. If we put the IP of the host it's ok.
We can not work like that because we want to use a round robin feature with several nodes in the same cluster. But for this issue I have only tested one of the node (so host + cop1 + domain).
We suspect it comes from the .net implementation because :
- ping and nslookup are fine : host is well translated to its IP by windows
- it's working if, instead of the host + domain we put the IP of the host.
- I have tested the Teradata Simba odbc driver 17.20 and everything works well. Other guys have tested the Teradata odbc driver 17.10 and it's also working with the host including domain. No particular option was set => all default ones.
- the log is showing an issue in the proxy tunnel method (sorry a part is in french => timeout) :
[0] Exception message: [.NET Data Provider for Teradata] [100002] Cannot create connection within the time specified.
