Hello,
on HP-UX (tested 11.23, checked 11.11) there is:
nogroup:*:-2:
Which leads to a rsync daemon that will fail upon connect:
[..]
chdir("/") ............................................... = 0
setgid(-2) ............................................... ERR#22 EINVAL
open("/usr/lib/nls/msg/C/strerror.cat", O_RDONLY, 032630) ERR#2
ENOENT
open("/usr/lib/nls/C///strerror.cat", O_RDONLY, 032630) .. ERR#2
ENOENT
time(NULL) ............................................... = 1130323189
getpid() ................................................. = 20543
(20542)
brk(0x40018000) .......................................... = 0
ioctl(5, TCGETA, 0x7f7f32b8) ............................. ERR#25 ENOTTY
write(5, "2 0 0 5 / 1 0 / 2 6 1 2 : 3 9 ".., 75) ....... = 75
select(5, NULL, 0x7f7f2520, NULL, 0x7f7f2730) ............ = 1
write(4, "@ E R R O R : s e t g i d f ".., 22) ....... = 22
exit(255) ................................................
WIFEXITED(255)
So I think there should be a hint in the README file stating that
building on HP-UX requires a "nobody" group with a postive gid to be
created in order to get a usable binary (tested & working).
Cheers,
