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

$sftp = New-Object Chilkat.SFtp

# Set some timeouts, in milliseconds:
$sftp.ConnectTimeoutMs = 5000
$sftp.IdleTimeoutMs = 10000

# Connect to the SSH server.  
# The standard SSH port = 22
# The hostname may be a hostname or IP address.

# Authenticate with the SSH server.  Chilkat SFTP supports
# both password-based authenication as well as public-key
# authentication.  This example uses password authenication.

    $($sftp.LastErrorText)

}

# Open a file for writing on the SSH server.
# If the file already exists, it is overwritten.
# (Specify "createNew" instead of "createTruncate" to
# prevent overwriting existing files.)
$handle = $sftp.OpenFile("hamlet.xml","writeOnly","createTruncate")

# -----------------------------------------------------------------------------
# This is important.  You must close the handle on the server.
# Otherwise open handles will accumulate on the server until eventually a limit
# is reached and the server will fail on a call to OpenFile.

# Close the file.
