Sì, SSH

Ancora niente

my $real_server = $server->create_server();my $root_pass = $real_server->adminpass();

Ora sì

my $id = $real_server->id();

RUNNING_CHECK:while ('necessary') { my $instance = $cs->get_server($id); say 'completion status: ', $server->progress(); if ($server->status eq 'ACTIVE') { say 'active, IP: ', $instance->public_address()->[0]; last RUNNING_CHECK; } sleep 1;}

Ora?SSH con $root_pass

O anche...

Sì... root passwordvia email

my $server = Net::RackSpace::CloudServers::Server->new( cloudservers => $cs, # N::R::CloudServers instance name => 'my-instance', imageid => 4, # Debian 5.0 (lenny) flavorid => 1, # basic server, 256 MB RAM personality => [ { path => '/root/.ssh/authorized_keys2', contents => <<END_OF_BASE64SUlKckNyZWIxcU5NcGxuS1BIaFBBdFIxL2RMUVJ6SnNzSnNxTWUwRENlbXp5NlVMZ0g3Uy9seWZU...anExQWhSaE1zK0FHaDZDL01aV1N4QStZNmhqd2wwMFozSVl1R3AgaW1wb3J0ZWQtb3BlbnNzaC1rZXkK

Chiave SSH
