Note that as an alternative shorter syntax you can use numbers e.g. '''666''' is equivalent to '''ugo+rw'''. The first digit in the number relates to ''u'', the second to ''g'' and the last to ''o''. The values in [] brackets in list of permissions above are added to derive each digit. So if you are reading the Cumulus support forum and you see a reference to permissions which includes a string of 3 digits, now you can understand what is meant. | |||
