# 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 = 15000

# Connect to the SSH server.  
# The standard SSH port = 22
# The hostname may be a hostname or IP address.
$hostname = "sftp.example.com"
$port = 22
$success = $sftp.Connect($hostname,$port)

# Authenticate with the SSH server.  Chilkat SFTP supports
# both password-based authenication as well as public-key
# authentication.  This example uses password authenication.
$success = $sftp.AuthenticatePw("myLogin","myPassword")

# After authenticating, the SFTP subsystem must be initialized:
$success = $sftp.InitializeSftp()
if ($success -ne $true) {
    $($sftp.LastErrorText)
    exit
}

# Open a file on the server for writing.
# "createTruncate" means that a new file is created; if the file already exists, it is opened and truncated. 
$handle = $sftp.OpenFile("myTest.txt","writeOnly","createTruncate")
if ($sftp.LastMethodSuccess -ne $true) {
    $($sftp.LastErrorText)

if ($success -ne $true) {
    $($sftp.LastErrorText)
    exit
}
