Yes. IBM's AIX login is responsible for cleaning up the utmp file. It
has been APAR'd several times. However, the best solution I can give
you is to use the following program (utmpfix) that has been passed
around somewhat to keep the utmp file clean:
#if defined(LOGGING)
#include <stdio.h>
#endif
#include <sys/types.h>
#include <utmp.h>
#include <fcntl.h>
main (int argc, char *argv[])
{
int fd;
struct utmp utmp;
#if defined(DAEMON)
while (1) {
#endif
if ((fd = open ("/etc/utmp", O_RDWR)) >= 0) {
while (read (fd, &utmp, sizeof utmp) == sizeof utmp) {
if (utmp.ut_type == USER_PROCESS &&
kill (utmp.ut_pid, 0) != 0) {
lseek (fd, - (long) sizeof utmp, 1);
utmp.ut_type = DEAD_PROCESS;
write (fd, &utmp, sizeof utmp);
#if defined(LOGGING)
printf("%s zapped: %8.8s %12.12s\n",
argv[0], utmp.ut_name, utmp.ut_line);
#endif
}
}
close (fd);
}
#if defined(DAEMON)
sleep (60);
}
#endif
}
