lastb command

[redhat at buglecreek.com]

I would like to use the lastb command.  I have created /var/log/btmp and
tried some unsuccessful logins.  It seems that only failed login
attempts from a tty* are logged.  "last" and "lastlog" shows both remote
and local logins. Does lastb only support local failed login attempts?
I know that these failed remote attemps get logged in /var/log/messages,
but would like to see them with lastb.

Thanks
