Great, thanks for the help (I'm fairly new to Python, didn't know about ctypes)
from ctypes import * libc = CDLL("libc.so.7") size = c_uint(0) libc.sysctlbyname("net.inet.ip.stats", None, byref(size), None, 0) buf = c_char_p(" " * size.value) libc.sysctlbyname("net.inet.ip.stats", buf, byref(size), None, 0) So now that I've got the data, can you point me towards docs explaining how to layout struct ipstat?
