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

ssh = Chilkat::CkSsh.new()

# Hostname may be an IP address or hostname:
hostname = "www.some-ssh-server.com"
port = 22

# Connect to an SSH server:
success = ssh.Connect(hostname,port)
if (success != true)
    print ssh.lastErrorText() + "\n";
    exit
end

# Wait a max of 5 seconds when reading responses..
ssh.put_IdleTimeoutMs(5000)

# Authenticate using login/password:
success = ssh.AuthenticatePw("myLogin","myPassword")
if (success != true)
    print ssh.lastErrorText() + "\n";
    exit
end

# Once the SSH object is connected and authenticated, we use it
# in our SCP object.
scp = Chilkat::CkScp.new()

# The byte representation of the remote text file (i.e. the charset) must be
# indicated to allow the receiving software to correctly interpret the incoming
# bytes as the correct chars.
# See https://www.chilkatsoft.com/p/p_463.asp for a list of valid charset names.
