    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 .
    drwxr-xr-x 8 root wheel 512 Mar 25 15:28 ..

    ---------- 1 root wheel 94 Mar 26 08:47 new.c
    -r-x------ 1 root wheel 15430 Mar 25 15:16 new.pl
    -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
