SFTP Upload from Local Filesystem

See more SFTP Examples

Demonstrates how to upload a file to an SSH server. There are no limitations on file size, and the file is streamed directly from the local filesystem. Perl

use chilkat();

$success = 0;

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

$sftp = chilkat::CkSFtp->new();

# Set some timeouts, in milliseconds:
$sftp->put_ConnectTimeoutMs(5000);
$sftp->put_IdleTimeoutMs(10000);

# 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,$port);
if ($success != 1) {
    print $sftp->lastErrorText() . "\r\n";
    exit;
}

# Authenticate with the SSH server.  Chilkat SFTP supports
# both password-based authenication as well as public-key
# authentication.  This example uses password authenication.
$success = $sftp->AuthenticatePw("myLogin","myPassword");
if ($success != 1) {
    print $sftp->lastErrorText() . "\r\n";
    exit;
}

# After authenticating, the SFTP subsystem must be initialized:
$success = $sftp->InitializeSftp();
if ($success != 1) {
    print $sftp->lastErrorText() . "\r\n";
    exit;
}

# 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 = $sftp->openFile("hamlet.xml","writeOnly","createTruncate");
if ($sftp->get_LastMethodSuccess() != 1) {
    print $sftp->lastErrorText() . "\r\n";
    exit;
}

# Upload from the local file to the SSH server.
$success = $sftp->UploadFile($handle,"c:/temp/hamlet.xml");
if ($success != 1) {
    print $sftp->lastErrorText() . "\r\n";
    exit;
}

# -----------------------------------------------------------------------------
# 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.
$success = $sftp->CloseHandle($handle);
if ($success != 1) {
    print $sftp->lastErrorText() . "\r\n";
