User name is "admin", passwd is the original passwd for root when installation was done.
However, if you forget that passwd (like I did), go to: /usr/internet/admin/access
vi .htpasswd
you'll find a line starting with "admin:XXXXX" where XXXXX is the encrypted passwd, you can read in the shadow file and copy the encrypted passwd from root or any other user, and that will be the active passwd at that point
