[Why] even network interfaces ready, but routing not, get ip by routing failed, so add a check export_ip_mac to ensure network is ok.
[how] before: network interfaces "up"|"1" -> network is ok after: network interfaces "up"|"1" && export_ip_mac ok -> network is ok
in "Why", get ip by routing failed, how about optimize it.
Can help me test the file /proc/net/route, where the kernel records the routing information. root@dewan01:~# cat /proc/net/route Iface Destination Gateway Flags RefCnt Use Metric Mask MTU Window IRTT eth0 00000000 0100A8C0 0003 0 0 100 00000000 0 0 0
while: do if [ -f /proc/net/route ];then PUB_NIC=$(ip route get ...) ... break else sleep 1 fi done
Thanks, Dewan
