Chilkat Perl Downloads Perl Module for Windows, MacOS, Linux, Alpine Linux, Solaris

use chilkat();

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

$ssh = chilkat::CkSsh->new();

# To get the authentication methods offered by an SSH server, we first connect.
$success = $ssh->Connect("example.com",22);
if ($success != 1) {
    print $ssh->lastErrorText() . "\r\n";
    exit;
}

# Next, we call GetAuthMethods to receive a comma separated list of authentication methods
$authMethods = $ssh->getAuthMethods();
if ($ssh->get_LastMethodSuccess() != 1) {
    print $ssh->lastErrorText() . "\r\n";
    exit;
}

# For example: publickey,password,keyboard-interactive
print "Authentication methods suported by this serve: " . $authMethods . "\r\n";

# IMPORTANT:
# Getting the authentication methods will intentionally disconnect from the server.
# We'll need to re-connect, etc. to continue..

# For example..
$success = $ssh->Connect("example.com",22);
if ($success != 1) {
    print $ssh->lastErrorText() . "\r\n";
    exit;
}

$success = $ssh->AuthenticatePw("myLogin","myPassword");
if ($success != 1) {
    print $ssh->lastErrorText() . "\r\n";
    exit;
}

print "SSH Authentication successful." . "\r\n";

# ...

$ssh->Disconnect();
