This is a wrong assumption for the reason I explained above.

SecureBlackbox version 5 that you use doesn't support key renegotiation. So it can't be doing anything like that when you send the data.

Okay maybe it's not doing key re-exchange but it's doing something. I have proof of that, I have a trace. Would you like to see it?

The SSH exchange is being initiated by the server, not my app. If SBB version 5 doesn't support key re-exchange what does it do if it receives such a request from the server?

JFYI: after 2 hours of inactivity TCP keep-alive packet is sent by TCP/IP stack to check the state of connection.

OR maybe it's the server that initiates rekeying.

In any case it makes little sense to discuss behavior of the old version of the component, which doesn't support rekeying. If you moved to version 7, which is the most recent version, it's possible that the problem would disappear automatically. Or we would be able to narrow it down a bit (by excluding or confirming that rekeying takes place).

I'm really against upgrading since it may destabilize my product. Looks like you've got me by the balls though!
