Hi Edison,

Please let me confirm which "SSH" and "the Switch's shell" means.
You want to control the behavior of your switch via SSH command line interface 
from Ryu, right?
If so, Ryu does not provide such features for SSH CLIs.

If your switch supports OVSDB, you can use OVSDB library of Ryu.
  
https://github.com/osrg/ryu/blob/0673a8868e4447e7b2ec551c720aeb929993727d/ryu/lib/ovs/bridge.py#L92

Or if you means the CLI commands like Linux bash, I guess you need to implement 
it by using
Ansible or other provisioning tools.

Thanks,
Iwase

Hi.
Once I have a SSH connection between Controller and Switch, how can I access the Switch's shell from inside Ryu?
Tks.
