Synology DSM Recovery Telnet Password of the Day generator
If a DSM update fails the boot loader will enable telnet to make it possible to recover from the failed DSM update. The DSM recovery telnet password was originally blank. Later Synology changed it to 101-0101
If a blank password or 101-0101 does not work you need to either contact Synology Support for the 'password of the day', or you can run this script which will show you the 'password of the day'.
The script can run on a Synology NAS or any computer or NAS that has bash.
You can run the script with --day=X and --month=Y to get the telnet password for day X of month Y.
Usage: dsm_telnet_password.sh [options]
Options:
--day= Set the day to calculate password from
If --day= is used you must also use --month=
Day must be numeric. e.g. --day=24
--month= Set the month to calculate password from

Month must be numeric. e.g. --month=9
