DESCRIPTION
The log file /var/log/lastlog keeps track of the last successfull login
of each user on the system. Not all programs logs this data and for
some this is configurable. The content of this file can be printed
with the lastlog(8) command. Every entry has a fixed length, the file
is indexed by numerical UID. Each record contains the time, port and
originating host that were used for the login.
The structure of the file is
struct lastlog {
#if __WORDSIZE == 64 && defined __WORDSIZE_COMPAT32
int32_t ll_time;
#else
time_t ll_time;
#endif
char ll_line[UT_LINESIZE];
char fail_host[UT_HOSTSIZE];
};
