Problem is a 16 byte buffer in SIOCGIFCONF ioctl. This was reported
more than a year ago in PR#11525 by Mark J. Taylor.
As a default system has already 9 interfaces (sl0, ppp0, lo0, gif0,
gif1, gif2, gif3, faith0 and your network interface), 16 bytes is
too small.
Seems like rarpd.c never got cleaned up?

syslog(LOG_ERR, "socket: %m");
exit(1);
}
ifc.ifc_len = sizeof ibuf;
ifc.ifc_buf = (caddr_t)ibuf;
if (ioctl(s, SIOCGIFCONF, (char *)&ifc) < 0 ||
