SFTP Upload from Local Filesystem

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. Chilkat2 Perl

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

my $sftp = Chilkat2::SFtp->new;

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

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

# both password-based authenication as well as public-key
# authentication.  This example uses password authenication.

# 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.)

# This is important.  You must close the handle on the server.
