Any suggestions? I spent a little time debugging this but still need some help understanding what might be wrong. Instrumenting dump_sa() in the AF_INET case, the .sin_addr contains the value of the IP address I'm adding (printf shows 0x0a05a8c0 or big endian 192 168 6 10). Switching the log level in sys/netlink/route/iface.c to LOG_DEBUG3 shows messages: [nl_iface] dump_iface_addr: dumping ifa 0xfffff8000db0cd80 type inet(2) for interface igc0 Does this mean the address information was written to the net link buffer? If so, what might make ifconfig not display that address? One other tidbit is, eventually ifconfig reports the address and things like sshd start working. Typically this takes < 100 iterations to do this.
