Raspberry pi3 Ubuntu aktivacia LAN adaptéra

[josefskopik92]

prosím o radu, možná to tady nepatří,

mam rpi 3 b+ nastavoval jsem jej na wifi, nyni jsem jej zapojil na lan a pripojuje se stale jen pres wifi, prosim, jak uprednostnit aby jela lan ?

[chocholousek]

Zapomel si nam prozradit jak mas propojene LAN a WIFI, jestli premostenim nebo pres NAT napriklad pres masqueradu? Ono tech moznosti je vice nez jedna ale odkud kam se da utrcit napriklad pomoci routovac tabulky a nastavenium metric se da urcit poradi v jakem to ma zkouset.i

[josefskopik92]

snandart mam pripojene rpi lan kabelem k routeru a pres wifi k routeru, wifi jde, jakmile vypnu wifi, lan se sam nepripoji, potrebuji aby uprednostnoval lan

[chocholousek]

Takze nemas nastaveno bud premosteni a nebo onu masqueradu ted musis vedet jak to chces udelat naistalovat prislusne baliky a nastavit.

[josefskopik92]

mam pripojene kabelem, potrebuji aby nejela wifi ale vzalo to dhcp ip od routeru ale pres lan

[chocholousek]

Tak budu tipovat pac vubec netusim jak to mas udelane, pokud chces uplne vypnout wifi a trvale zapnout lan kartu musis nejspis v networmanageru vse prepsat vymazat wifi a doplnit lan kartu. Pochop netusim jaky mas OS netusim jaky mas spravce pro sit atd atd...

[josefskopik92]

mam tam ubuntu server

[josefskopik92]

[josefskopik92]

[josefskopik92]

[josefskopik92]

nechápeme se .... nechci nic s wifi, chci aby mi eth0 detekoval pres dhcp ip adresu a wifi nebyla funkcni .... ted jede jen wifi a lan nejde, ikdyz wifi vypnu

kdyz zadam netplan /etc/netplan/90_config.yaml

usage: /usr/sbin/netplan [-h] [--debug] ...
/usr/sbin/netplan : error: argument : invalid choice: '/etc/netplan/90_config.yaml' (choose from 'help', 'apply', 'generate', 'get', 'info', 'ip', 'set', 'rebind', 'status', 'try')

[chocholousek]

Ale chapeme, kdyz v vymazes zminky o wifi /etc/netplan/90_config.yaml prestane pro netplan existovat, treba pres vi co ja vim co tam mas za editor textu?? A logicky kdyz v /etc/netplan/90_config.yaml nemas nic o LAN karte musis doplnit, o5 kdyz tam lan neni nebude fungovat a zacne az to doplnis.

[josefskopik92]

ale nenam to kam doplnit kdyz mi to na netplan /etc/netplan/90_config.yaml nereaguje ....

[chocholousek]

/etc/netplan/90_config.yaml je obyc textovy soubotr edituj cimkoliv co tam mas a umi editovat textove soubory!

[josefskopik92]

zarati me kdyz dam route

neukazuje se eth0

[josefskopik92]

nepotrebuji to cele shodit a instalovat opet znova

[chocholousek]

Jakmile nastavis netplan a das netplan apply ten upravi i routovaci tabulku, netplan nedovoli aktuivaci spatneho configu neprojde to pokud tam mas chybu (velkou). shodit? maximalne se dostavis primo k pi pres terminal nemuzes to skokotit tak ze to budes muset preinstalovavat
mozna ano nevim jak moc si (ne)sikofny.

[josefskopik92]

chci jej vytvorit primo v putty pod root takze sudo pico /etc/netplan/config.yaml ?? a zadat tam
network:
version: 2
renderer: networkd
ethernets:
eth0:
dhcp4: true

tim padem poejde jen lan a pres dhcp ?
