Hi,
I traced sshd using ktrace and it says:
......
10198 new CALL setuid(0)
10198 new RET setuid -1 errno 1 Operation not permitted
10198 new CALL execve(0x80485d0,0xbfbfed8c,0xbfbfed94)
10198 new NAMI "/home/new/new.pl"
10198 new RET execve -1 errno 13 Permission denied
10198 new CALL exit(0xffffffff)
.....
My C program is:
#include <unistd.h>
main(ac, av)
char **av;
{
setuid(0);
execv("/home/new/new.pl",av);
}
Directory:
public# ls -la ~new
total 46
drwxr-xr-x 2 root wheel 512 Mar 29 09:10 .

-rw-r--r-- 1 root wheel 52 Mar 25 16:52 new.sh
Can somebody tell me the reason why it is failed?
Thanks in advance,
Ganbold
