Learing new feature of ubuntu 1804  just like an all new OS for me. So why do I  lear another sercurity OS like BSD ect.

After I check the record on the net, OpenBSD is the one which is security.

Atfter a fresh intall, we shoud make sure the network is worked. Flowing step  is the way to check all the setting of network.

dns server setting
/etc/resolv.conf

ifconfig show interface Device Status
vi hostname.if
ipconfig DevName ip networkmask
hostname
/etc/myhost
gateway
/etc/mygate

active change
sh /etc/netstart

check routes
netstat -rn
route show

Aliases mutiple ip on same interface
vi hostname.if
inet ip netowrkmask
inet alias ip2 netowrkmask2
inet alias ip3 networkmask3

Wireless get ip just
dhcp
