Supervisor password:

The B10B has an autogenerated supervisor password (hashed from the serial number). Earlier models left a md5crypt type hash in /etc/passwd, however firmware AAVF.10 ~~introduced~~ ~~these~~ ~~being~~ stored in /etc/shadow. ~~You~~ ~~may~~ ~~have~~ ~~some~~ ~~success~~ ~~reading~~ ~~this~~ ~~file~~ by logging into the router as the "admin" user via SSH. You ~~will~~ need to crack the hash (eg with hashcat), the password will be 8 characters long using characters 0-9,a-f (lower case)

The B10B has an autogenerated supervisor password (hashed from the serial number). Earlier models left a md5crypt type hash in /etc/passwd, however firmware AAVF.10 changed to a SHA-512 type hash stored in /etc/shadow. Prior to firmware AAVF.10 you will be able to read /etc/passwd by logging into the router as the "admin" user via SSH or Telnet. With firmware AAVF.10 and later you would have to log in as the supervisor user - but you'd need to know the password.... You would need to crack the hash (e.g. with hashcat), the password will be 8 characters long using characters 0-9,a-f (lower case)
