(Go) Multi-Hop SSH (SSH Through SSH)

Demonstrates how to SSH through one SSH server to get to another SSH server. The scheme looks like this:

Application => ServerSSH1 => ServerSSH2

The ConnectThroughSsh method is added in Chilkat version 9.5.0.55 to accomplish this task. Technically, it should be possible to chain any number of servers using the ConnectThroughSsh multiple times:

Application => ServerSSH1 => ServerSSH2 ==> ServerSSH3 => ... => ServerSSHN

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    ssh1 := chilkat.NewSsh()

    // Hostname may be an IP address or domain name:
    hostname := "192.168.1.108"
    port := 22

    // Connect directly to the 1st SSH server:
