who seems to loose interest in the fact that tty1 is also being used.
initially i's shown after a restart but after a while it is missed.
maybe a kernel problem, maybe not :

I have seen this with many, if not all 2.4 kernels. this is 2.4.6.
tty1 _is_ active :
[....]
root 3857 0.0 0.4 2812 1120 tty1 R 08:46 0:00 ps aux
so.. kernel problem or sh-utils ?

I have discussed this with Roeland offline and we are both using XFree
4.02. I start my system with runlevel 3 (and so does Roeland?) and
then we run `startx &'. It is only after this that the `utmp' file
gets stomped. I am not quite sure how this could be a kernel problem.
I don't know where the code would be that touches `utmp'. I have sh-utils
versin 2.0 (freshly compiled) with Linux 2.4.7. I also wrote this code,
#include <stdio.h>
#include <stdlib.h>
#include <utmp.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <unistd.h>
int main(int argc, char *argv[])
{
int fd;
struct utmp loginEntry;
fd = open(_PATH_UTMP,O_RDONLY);
if(fd >= 0) {
while(read(fd,&loginEntry,sizeof(loginEntry))) {
printf("type %d, ", loginEntry.ut_type);
printf("pid %d, ", loginEntry.ut_pid);
printf("line %s, ", loginEntry.ut_line);
printf("id %s, ", loginEntry.ut_id);
printf("user %s, ", loginEntry.ut_user);
printf("host %s\n", loginEntry.ut_host);
}
close(fd);
}
else {
printf("Cann't open " _PATH_UTMP);
}
return 0;
}
I have attached the output of this code and my `ps -ef'. You can see
from the ps output that there is a user logged on tty1. I use lkml,
but not the sh-utils... feel free to contact me if you wish additional
information. I always see this after running `X', never before.
regards,
Bill Pringlemeir.
