SCAN trouble shooting

Folks, I'm able to connect using the actual node ip, but when trying scan ip, giving all sorts of errors, using /etc/hosts file, attached is my hosts file too.

Need some assistance to troubleshoot, what exactly is the problem.

Thanks
hosts

The "hosts" file does not provide any useful information,
And these errors you talk about, are they a special secret you wish to keep?
What about posting some screenshots that are not invisible?

99.999% of the time an ORA-12170 is a firewall issue.

from a CMD prompt post the results of:
ping 192.168.1.21
tracert 192.168.1.21

For us to troubleshoot the ORA-12545 we need to see the tnsnames.ora file from the machine where you executed that command.


Also, is there any reason you are using EZConnect for the first try and not for the second?

And no reason, basically was trying all options, whatever works ... :(

Which error do you wish to troubleshoot?

Based on your previous related questions I have to assume you are still trying to connect to the RAC cluster using the SCAN ip address so we can really ignore the attempts to connect to the local PROD instance?

If so, I don't see how this question is different than:

If this is a duplicate, one of them will have to be deleted.  There is a 500 point maximum for a single question.

Try the following commands from this document:
http://www.oracle.com/technetwork/products/clustering/overview/scan-129069.pdf

They should show the setup for scan.

srvctl config scan_listener
and
srvctl confic scan

Sorry, can't attach html, any way to share that report?

Thanks.

sorry Gurus ... my fault, I was trying to connect using cygwin and when tried putty, all looks good, I think, cygwin configuration needs to be checked.

I think, this question should be deleted ... please advice.

Thanks

I suggest you accept your last post as the answer in case anyone else ever tries connecting through cygwin.
