Missing Jumphost.java in the examples directory

[Tilden18]

In the Readme states the below

• JumpHosts.java
  This program will demonstrate SSH through jump hosts.

but the JumpHosts.java file is missing in the examples directory. c

I'm guessing this is it?

Hi @Tilden18,

FYI, I pulled the copy of this from the original author's site I noted above and have included it in PR #200.

Btw, this code seems to just use port-forwarding, so I don't believe operates in the same manner as OpenSSH's ProxyJump functionality (which I believe accomplishes jump host type functionality without using port-forwarding), if that is what you are looking for.

Thanks,
Jeremy

Hi Jeremy,
yes, I was looking for ProxyJump functionality (with Password and Key authorization). do you support this in jsch?

Similar to this.

Hi @Tilden18,

JSch doesn't currently support the ProxyJump specific directive as implemented in OpenSSH.
However, it should be possibly to perform something akin to it using port forwarding (as the JumpHosts.java example implements).
Also, from my limited understanding of SSHJ, the example you linked from it appears to be similar to the JumpHosts.java example, in that it utilizes port forwarding.

Thanks,
Jeremy
