Hi All,
I am trying to write a netconf subsystem for my testing purpose
using apache mina sshd server latest version.
The client is able to communicate with the server and everything is working
fine, until the connection is closed (either by client or due to some
signal). After that client tries to re-establish the connection to the
server, but it keeps failing with java.lang.IllegalStateException:
Unsupported command: 50. Please can someone help to overcome this situation.
My netconf subsystem implements the following interfaces public class
Jnetconf implements Command, SessionAware,ChannelDataReceiver,
ChannelSessionAware
