I’m curious about whether JSch can support a feature analogous to OpenSSH’s ProxyJump (or ControlMaster/ControlPersist)—often referred to as “SSH proxy multiplexing.” In OpenSSH, this feature allows multiple sessions to reuse an existing SSH connection, reducing the overhead of establishing multiple connections when forwarding traffic or tunneling through intermediate hosts.
Any guidance or suggestions on how to achieve similar behavior would be greatly appreciated.
