Dotaz: Začátky s Arch linux

[guuk]

Jak nastavit připojení k internetu? Připojení mám pres switch, který je připojený na ADSL-router. Adresu získávám automaticky přes DHCP. Při instalaci ( z FTP) bylo v dhcp.conf

IPADDR=192.168.123.100
NETMASK=255.255.255.0
NETWORK=192.168.123.0
BROADCAST=192.168.123.255
GATEWAY=192.168.123.254
DNS=192.168.123.254
DHCPSID=192.168.123.254
DHCPGIADDR=0.0.0.0
DHCPSIADDR=0.0.0.0
DHCPCHADDR=00:11:09:8C:BA:1D
DHCPSHADDR=00:C0:49:EB:31:6A
DHCPSNAME=''
LEASETIME=3600000
RENEWALTIME=1800000
REBINDTIME=3150000
INTERFACE='eth0'
CLASSID='Linux 2.6.16 i686'
CLIENTID=00:11:09:8C:BA:1D

Po skončení instalace je v rc.conf

zakomentuj eth0="eth0 192.168.0.2 netmask 255.255.255.0 broadcast 192.168.0.255" a pod to napis eth0="dhcp" (komentar je #) a pripadne se prid kuknout na IRC cko #archlinux.cz@irc.i.cz

[otula]

Vždyť to samo píše, že potřebuje --refresh, čili -y. Jinak tedy - je potřeba spustit pacman -Sy

[pasmen]

A co treba obycejny ping? ping 194.228.32.3 (IP adresa www.seznam.cz) ti rekne, jestli sit funguje.

[;)]

Vedeli by ste mi povedat, akeho DHCP klienta pouziva arch linux? D~

[bazil]

dhcpcd

[Goffix]

Ted uz zacinam chapat proc se Arch nedoporucuje na zacatek prace s Linuxem. Ono se prve musi naucit cist dokumentaci, helpy a pak se teprve hrabat v konfigurakach.

Nic proti, ale kdyz vidim v kazdy otazce rovnou i napsanou odpoved, tak nevim co jineho na to rict.

[guuk]

To ta moje děravá paměť. Dokumentaci jsem samozdřejmě čet, ale byl jsem v domění že refresh je Ss ale ono je to Sy.

[bazil]

v tom případě man cokoliv a je to ... btw i u toho konfiguráku byla odpověď napsaná o pár řádku nad tím ...

[Ivanhoej]

Este tam daj update

pacman -Syu
