When I first looked at this file a long time ago, I was under the
impression that it only recorded failed login attempts, but since it
was definately modified when I logged in just now, I guess I was
wrong. It definitely does record unsuccessful attempts, though;
even unknown login names.
Here's what I've been able to figure out from the file itself:
struct pwcntl
{
char name[8]; /* name entered at login: */
int uid; /* seems to be garbage for failed logins */
char flag; /* always 'Y' or 'N', what does it mean? */
/* char pad; */
long last_login; /* last login attempt */
long first_login; /* time when this entry was created */
long unknown; /* always zero, what does it mean? */
}; /* 26 bytes total */
Has anyone ever seen this file on anything other than a Unix PC?
Anyone with further observations/conclusions, please post!
