It's the sftp subsystem in Linux's SSH implementation that blocks the way
to get Sudo permission in sftp. Jsch is merely a re-implementation of SSH
protocol and for compatibility purpose, it just can't do that. The problem
lies in the sftp-server implementation, which is now deployed in nearly
every linux box. You've got a mission impossible, if you insist on doing
SUDO put/get with Jsch ChannelSftp.
