- this is a quick bash hack, to set overwrite the current ip with an fixed ip
- or add an virtual interface for an additional fixed ip
- this will (brute force) OVERWRITE all mess done by network managers of various origins
- here should be only one config file to config (to rule them all) network settings and it is:
- instead of 10x entities inventing it’s own standard, confusing the heck out of users, introducing unecessary complexity (UNIX KISS: KEEP IT SUPER SIMPLE) = asking for trouble
… or it will end up like USB mess of standards:
USB Cable Salad of Madness – USB 3.0 and WiFi interference – Micro-USB USB-C mess has finally arrived
in general syntax is:
ifconfig <interface> <ip_address> netmask <netmask> ip a add <ip_addr>/<mask> dev <interface>
let’s go then:
# become root su - root # install ifconfig legacy tool apt update; apt install net-tools; # checkout what interfaces exist ip -c a 2: enp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 # this will simply OVERWRITE the current ip setting of interface # and test ping the system trying to be reached 3x times while true; do ifconfig enp2s0 192.168.2.222 up; ip -c a; ping -c3 192.168.2.223; sleep 1; clear; done # this will ADD additional "virtualinterface:0" fixed ip to interface # so the interface will keep it's dhcp acquired ip plus the fixed ip, cool eh? while true; do ifconfig enp2s0:0 192.168.2.222 up; ip -c a; ping -c3 192.168.2.223; sleep 1; clear; done
this kind of bruteforce way of overwriting things can also be done for DNS: (there should be only ONE config file to config this /etc/resolv.conf, keep the standard!)
