Failed login attempts are recorded in syslog. Unfortunately, you need
source to get them to tell you where they came from (at least as of
Ultrix 3.1 - haven't seen 4.0 yet). We modified the source to tell us
where the login came from as well - it's a very simple fix - you just
have the syslog call put in the ut_host element of the utmp struct or,
if that's NULL (say on a dial up line, or a direct connect, or through
some sort of switch), the word "local". You might want to take a look
at the BSD source. I'm pretty certain it's available by anonymous ftp
from uunet.uu.net, but I can't connect there right now to make sure.
As I recall, the Ultrix source isn't too far removed from it.

Other than the source, I haven't seen anything.
