@spew I've changed a few things in the heartbeat mechanism for 0.11.0. Could you retry and see if this still happens, and else give me a small program that shows...

Great, let me know!

Is this the same issue as #624?

dynamic port forwarding sets up a bound SOCKS server on the localhost that allows tunnelling other connections.

Unfortunately I do not think this will work. Zip is different from zlib and both algorithms are unable to read eachother's data.

`connection refused` means that either the port is blocked or firewalled. You need the SSHCLient to use SFTP.

What is causing the core dump? Keep in mind that the lib does a lot more than "just opening a socket".

Core dumps, or segv's of this kind are not in the library, also see the dump you posted. It's deep in C/native code. I cannot help here.

What is the problem? The disconnect? What is the server side saying there? It is opening a `shell` on the remote end, which leads to the disconnect. Maybe the Cisco...

Sure it does... I dumps its logs somewhere. What is the trace of connecting with jsch? What are you attempting to do?
