I created the following code:
#include <stdio.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <ifaddrs.h>
int main (int argc, char *argv[])
{
int rc;
struct ifaddrs *ifi;
rc =3D getifaddrs (&ifi);
printf ("rc =3D %d\n", rc);
}
Compiled it with debugging and ran it. after the getifaddrs call (it =
returned 0), there were 3 entries in the table. All 3 have the name of =
"".=20
I commented out the networking calls in rc.conf, rebooted the machine =
and then ran the code. Same result. I rebooted in single user mode and =
ran the code and the same results. The boot process is not setting the =
interface names properly. Whats even more fascinating about this is I =
have upgraded other machines (although they are newer) from 9.3 to =
11.0-RC1 and they worked just fine.
