[JSch-users] SSH key forwading

[Sachith Withana]

Hi all,

Does JSCH support SSH key forwarding capability?

Problem would be to copy a file from one server to another using my public
key.

I did it using the terminal. I'm wondering how to implement that through
jCraft.

Any help is appreciated!

Yes, it does.

JSch jsch = new JSch();
jsch.addIdentity("/home/foo/.ssh/id_rsa"
// , "passphrase"
);
...
Channel channel=session.openChannel("shell");
((ChannelShell)channel).setAgentForwarding(true);
...
channel.connect();

By using jsch-agent-proxy[1], you don't have to handle
the private-key file by yourself. You can use ssh-agent or Pageant as you
have done usually on the terminal. Refer to its example[2].
