connection problem

[Sarah Ichiba]

Hey there,

I Have cassandra server running on a VM and I'm trying to configure this server as a backend for Freeradius server. I'm using cassandra 2.0.15. The server is running normally. I can connect to it locally by just typing cqlsh. Now when freeradius looking to joint the cassandra server it's complaining that no host is found. I suspect that the problem is related to the cpp driver. Below the errors. If they're familiar to you, plz let me know how I can fix them.
Thanks in advance,
Sara

I'm not sure it's a driver issue, but I would need more information. It looks like there is an issue connecting to the locally running Cassandra node. The connection to that node timed out and left the driver with no other node to connect to.

I'm seeing the same thing, latest versino of cassandra, and latest versin of the cpp driver.

In a network trace, I can see that the connection is being established, but the client never sends its protocol version

[Uffe Gavnholt]

And I can confirm that the 2.0.1 driver works

[Michael Penick]

That network trace would be expected, because the connection timed out. It's possible for a connection to be established after the timeout period expires, but in that case the rest of the negotiation with Cassandra does not proceed.

What's strange in that trace is it looks like the connection is timing out after 1 ms, but it's hard to tell. Any additional information would be helpful.

I am having the same issue, i am lead to believe it is the driver myself because i am able to connect from my local machine, but not vm to vm...if you found an answer please let me know. Thanks

[Alex Popescu]

Josh can you connect from 1 vm to the other using cqlsh?

{:> alex :<}

[Josh Cooper]

Alex, yes i can cqlsh from one node to another

What version of the driver are you using? What platform are you using the driver from?
