|Our application is transferring data via SCP on a channel and randomly
|it will encounter the following error when transferring:
...
|The application then attempts to get a new session using:
|jsch.getSession(username, hostname, port);
|It fails to reconnect with the following error (partial stack trace):
|Caused by: com.jcraft.jsch.JSchException: SSH_MSG_DISCONNECT: 2 Protocol
|error: expected packet SSH_MSG_USERAUTH_REQUEST, got SSH_MSG_CHANNEL_OPEN
| at com.jcraft.jsch.Session.read(Session.java:899)
| at com.jcraft.jsch.UserAuthNone.start(UserAuthNone.java:85)
| at com.jcraft.jsch.Session.connect(Session.java:350)
It seems to me that Session#connect() method has been re-invoked.
Whenever establishing a new session, you need to get a new instance with
jsch.getSession(username, hostname, port);
and invoke its connect() method.
By the way, it seems the session is still alive,
because "SSH_MSG_CHANNEL_OPEN" has been returned.
Sincerely,
