Hi again,
I wrote a simple C program:
#define PYTHON "/home/mikib/t.py"
main(argc, argv)
char **argv;
{
setreuid(0,0);
setregid(0,0);
execvp(PYTHON, argv);
}
But after I compiled the C program and run it the Pyton program did not run
as 'root' user, and I'm getting this error:
Traceback (most recent call last):
File "/home/mikib/t.py", line 5, in ?
tt = file("/opt/ttt/1.txt","a")
IOError: [Errno 13] Permission denied: '/opt/ttt/1.txt'
I'm running Linux UBUNTU 6.10 :)
all I need is to write to some files that the users does not have a
permissions to those files like /etc/hosts.
Any idea how in Python I can open a file for write mode with privileges?
Thanks for any help,
Miki
