Perl Requires Chilkat v9.5.0.55+

Multiple Hop SSH to SFTP

See more SFTP Examples

Demonstrates how to SFTP through an intermediate SSH server (multiple hop). The scheme looks like this:

Application => ServerSSH1 => ServerSFtp

The ConnectThroughSsh method is used to accomplish this task.

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

my $ssh1 = Chilkat2::Ssh->new;

# Hostname may be an IP address or domain name:
my $hostname = '192.168.1.111';
my $port = 22;

# Connect directly to the 1st SSH server:
my $success = $ssh1->Connect($hostname, $port);
if (!$success) {
    print $ssh1->LastErrorText, "\n";
    exit;
}

# Authenticate using login/password:
$success = $ssh1->AuthenticatePw('myLogin', 'myPassword');
if (!$success) {
    print $ssh1->LastErrorText, "\n";
    exit;
}

# Connect through the 1st SSH connection to reach a 2nd SSH server (for SFTP)
# Note: Any number of connections may be simultaneously tunneled through a single
# existing SSH connection.
my $sftp = Chilkat2::SFtp->new;

# Connect to some SSH/SFTP server through ssh1.
$success = $sftp->ConnectThroughSsh($ssh1, 'sftp.someremoteserver.com', 22);

# Authenticate with the SFTP server.

if (!$success) {
    print $sftp->LastErrorText, "\n";

# Important -- the remote filepath is the 1st argument,
# the local filepath is the 2nd argument;

# The connection with ssh1 is still alive, and may be used for more connections.
