How were NET_PROTO_CONF_ALL and NET_PROTO_CONF_DEFAULT intended to be used? I tried out the /proc/sys/net/ipv4/conf/default and /proc/sys/net/ipv4/conf/all. Both directory entires are writeable. How do they differ? Thank you very much, Mingqin -- Kernelnewbies: Help each other learn about the Linux kernel.
