Hi,
Is there a workaround for using getpwuid() after you've chroot'd at all? - e.g.
with the code below?
I think the reason it _doesn't_ work is because once you've chroot'd the system
can't get back to the '/etc/pwd.db' file etc.? - Is there any way round this?
Apparently the following code does actually work on other systems... Someone
mentioned Linux, but I don't have access to any Linux boxes to test it ;-)
Regards,
Karl Pielorz

#include <stdlib.h>
#include <stdio.h>
#include <unistd.h>
#include <pwd.h>
int main()
{
setpassent(1);
getpwent();
chroot("/usr");
chdir("/");
if(!getpwuid(0)) {
printf("setpassent doesn't appear to work\n");
} else {
if(!getpwuid(0))
printf("second getpwuid(0) didn't work\n");
else
printf("setpassent works\n");
}
return 0;
}
