And if you run "ifconfig -a" and the > interface _is_ listed, this makes the whole thing even more strange... 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.
