Implement proxy jump using libssh
Implement #178
Recursively jump jump hosts till the first jump, which is to be made by client.
This has been tested with linux containers locally. Currently the torture_config
test is failing because it checks ProxyCommand
after doing a proxy jump, we don't set it now.
Need some advice on the following things:
- Error handling of the intermediate connection.
- Better/Another way of verifying host, instead of using
verify_knownhost
from examples. I used it for testing. - Cleanly exiting the IO forwarding. And the condition for the loop.
