Nefunkční net

[robert]

Ahoj,
právě jsem na desktop nainstaloval xubuntu a nemůžu rozjet síť. Mám adsl modem s routerem a natem, na něm mám navěšený ještě switch, pač na modemu jsou jen 2 rj45, Vše jede na DHCP. Na jednom desktopu mám starý Mandrake, na notebooku Mandrivu 2006 a tam net bez problémů jede.
Na Xubuntu sice v konzole pingám krásně všude, ale http nejede a při pokusu o
sudo apt-get update se mi to pokouší připojit na neexistující 1.0.0.0

síťovka je integrovaná na základní desce, procesor Athlox 1800 XP

[romi]

kedze ti nastavenie eth nastavuje cez dhcp, tak napis:

sudo dhclient eth0

ak to nepomoze, tak si to nastav rucne ..

[robert]

píše mi to:
Listening on LPF/eth0/00:11:2f:40:04:50
Sending on   LPF/eth0/00:11:2f:40:04:50
Sending on   Socket/fallback
DHCPREQUEST on eth0 to 255.255.255.255 port 67
DHCPACK from 10.0.0.138
bound to 10.0.0.2 -- renewal in 1429 seconds.

nicméně žádná změna

[romi]

naslo ti dhcp server...a nastavilo setko, co bolo treba ///
niekedy sa stava, ze sa nenastavi adresa dns servera a smerovaca (gateway) ... preto je najlepsie si vsetky parametre nastavit rucne..

najsitejsie je to priamo v konfigoch.. .cize... :

- nastavenie ip adresy rozhrania (sietovky) + maska podsiete a ip adresa brany (gateway, router) v /etc/network/interfaces a tam:

     auto eth0
     iface eth0 inet static
     address      netmask
     gateway

- ip adresu dns servra/-ov  /etc/resolv.conf a tam:

     nameserver
     nameserver

- a nakoniec restart sluzby networking:

     sudo /etc/init.d/networking restart


ted by ti to malo ist .. .samozrejme, ze tie adresy potrebujes vediet zistis ich napr z nastavenia siete vo windowse..alebo priamo na tvojom smerovaci (adsl modeme)

[robert]

V /etc/network/interfaces mám:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp
address 10.0.0.2
netmask 255.255.255.0
gateway 10.0.0.138

auto eth1
iface eth1 inet dhcp

auto eth2
iface eth2 inet dhcp

auto ath0
iface ath0 inet dhcp

auto wlan0
iface wlan0 inet dhcp


iface dsl-provider inet ppp
provider dsl-provider

zkousel jsem i static

v /etc/resolv.conf mám:

nameserver 10.0.0.138

po restartu mi to píše:

pokud dám static, tak tam údaje o eth0 vůbec nejsou

výsledek je ale stále stejný - web ani aktualizace nejedou, ping na cokoliv jede krásně

[romi]

takze vsetko mas nastavene cez dhcp ... takze teoreticky by to malo ist

ked pingas, tak pingas co? pocitace v tvojej lokalnej sieti? tie by mali ist bez problemov, vsak.

skus ping na nieco z internetu .. napriklad:
     ping 194.160.170.11
  co je vlastne
     ping www.sanet.sk
ak ti pojde ping na ip adresu a druhy nie, tak je nejaka chyba v dns.. ak to nepojde vobec, tak mas problem s prekladom adries, pripadne so smerovanim, tak pre istotu sem hod vypiz z prikazu:
     route

[robert]

Pingam na doménové jména www.seznam.cz www.google.com atd... ping na vnější IP adresy taky jede.

[romi]

a nemas nahodou nejak divne nastaveny firewall? napr zakazany pristup na/z privatnych adries?? ale kedze pises, ze si xubunt prave naisntaloval, tak nic take nebude :/
pre istotu napis:
     sudo iptables -F (to by malo vycistit iptables..)

ale nechapem, preco sa nevie dostat do sveta inak, ako cez icmp ...

skus si pustit ubuntu live ... a ci to tam pojde. . .

[Pavelp]

Zkontrolujte nastaveni nameseveru, v /etc/resolv.conf by melo byt:
nameserver ip_adresa_routeru

A zkuste tam pripadne pridat jeste nejaky nadrizeny nameserver poskytovatele.

Restartujte modem pred kazdym pokusem.

[robert]

v resolv.conf mám:

nameserver 10.0.0.138

tady mám log z modem/routeru:

kde 62.177.... je vnější IP

pokud nabootuju z live distribuce, tak síť taky nejede

[Pavelp]

Zkusil bych do resolv.cof pridat ty zalozni nameservery 212 a 195, aspon zkusit, on je dhclient zase premaze.
A vypnout Ipv6, navod je tady v sitich.

[robert]

Pokud vyhodím z resolv.conf 10.0.0.138 a nastavím tam ty skutečné DNS (212 + 195) + nastavím si statiku a vyberu nějakou vnitřní IP z povoleného rozsahu, tak to jede.

Ipv6 jsem nevypínal

Díky moc  rady
