SCP Sync Tree Download

See more SCP Examples

Synchronize local and remote directory trees by downloading newer or missing files from the remote server. Perl

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

# Connect to an SSH server:

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

    print $ssh->lastErrorText() . "\r\n";

$success = $ssh->AuthenticatePw("myLogin","myPassword");

# Once the SSH object is connected and authenticated, we use it
# in our SCP object.

# Download synchronization modes:
# mode=0: Download all files
# mode=1: Download all files that do not exist on the local filesystem.
# mode=2: Download newer or non-existant files.
# mode=3: Download only newer files.  
#         If a file does not already exist on the local filesystem, it is not downloaded from the server.
# mode=5: Download only missing files or files with size differences.
# mode=6: Same as mode 5, but also download newer files.
