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
