const GuacamoleOpennebula = require('guacamole-opennebula');

const clientOptions = {
crypt: {
cypher: 'AES-256-CBC',
key: 'here the secret key'
},
allowedUnencryptedConnectionSettings: {
rdp: ['width', 'height', 'dpi'],
vnc: ['width', 'height', 'dpi'],
ssh: ['color-scheme', 'font-name', 'font-size', 'width', 'height', 'dpi'],
telnet: ['color-scheme', 'font-name', 'font-size', 'width', 'height', 'dpi']

return callback(new Error('Token expired'))
}
return callback(null, settings)
}
}

const guacdPort = 4822
const guacdHost = '127.0.0.1'

const guacamole = appServer => {
if (
appServer &&
appServer.constructor &&
appServer.constructor.name &&
appServer.constructor.name === 'Server'
) {
const guacamoleServer = new GuacamoleOpennebula(
{ server: appServer, path: endpointGuacamole },
{ host: guacdHost, port: guacdPort },
clientOptions,
clientCallbacks
)
guacamoleServer.on('error', (clientConnection, error) => {
