I'm still not getting checkpassword trace with strace -ff :-(, but
here's what I do get (I've put the initialization at the end, because
it's more boring). [Could that lack of a trace be a sign of the
problem? After all, it seems like qmail-pop3d is getting the
environment qmail-popup has, not the one checkpassword should be
making]
I've made a small change to qmail-pop3d.c, in main(). I added
void main(argc,argv)
int argc;
char **argv;
{
char *home_dir;
sig_alarmcatch(die);
sig_pipeignore();
getuid(); /* <------ Added */
if (!argv[1]) die_nomaildir();
home_dir = getenv("HOME"); /* <------ Added */
if (! home_dir) die_nomaildir(); /* <------ Added */
if (chdir(home_dir) == -1) die_nomaildir(); /* <------ Added */
if (chdir(argv[1]) == -1) die_nomaildir();
getlist();
okay();
commands(&ssin,pop3commands);
die();
}
You'll note the lines in the trace that comes from the additions:
[pid 5970] getuid() = 0
[pid 5970] chdir("/root") = 0
I was getting the same basic results before I added these changes,
too.
