Adsl modem u router mode-u

gamepad · March 7, 2009, 1:41pm

imam 2 racunara i na jednom od njih koristim ubuntu 8.04. Do prije nekoliko dana sam se mogla normalno konektovati na net, ali posto je bihnet sada uveo neko pravilo da se moze konektovati, tj. da samo jedan racunar moze biti konektovan kada je modem u bridge mode-u, morala sam ga postaviti u router mode. sada na ubuntuu vise ne mogu na net. pomoc?

Koji router? Na tom drugom je internet OK ( Windows? ). Hajde daj output komandi:

sudo ifconfig
ping 192.168.1.1 (ovo je gotovo pa standard za routere)
cat /etc/network/interfaces

Router je Paradigm ADSL2/2+, konekcija pppoe. Da, na drugom racunaru imam XP i net radi. Output je sljedeci:

sudo ifconfig

Hajde uradi: sudo gedit /etc/network/interfaces , izbrisi sve sto ima i ubaci ovo:

.

The loopback network interface

auto lo
iface lo inet loopback

The primary network interface

allow-hotplug eth0
iface eth0 inet dhcp

Sacuvaj,restartuj i to je to : )

uradila sam. ipak nije to to… ideje?

amar-ze · March 8, 2009, 1:27pm

Hmm… Kako je mreza postavljena na Windows masini ? Jel obtain IP automatic? Jel ukljucen dhcp na routeru? Hajd probaj sudo ifconfig eth0 dhcp

gamepad · March 8, 2009, 1:47pm

da, IP se dodjeljuje automatski i dhcp je ukljucen, ali sudo kaze da je dhcp unknown host.

Cudno… Hajde onda probaj u onaj interfaces staviti ovo:

Sacuvaj, uradi /etc/init.d/networking restart te zatim daj output sudo ifconfig komande i sudo route -n

gamepad · March 8, 2009, 2:50pm

amar-ze · March 8, 2009, 3:04pm

Hajde sad kad nece milom hoce silom… ako ovo ne uspije provjeri kablove/mreznu :mrgreen:

Otidji na Windows komp. idi Start>Run>ukucaj cmd>Enter> ukucaj ipconfig>Provjeri da pod gateway stoji 192.168.1.1 i provjeri koja je IP adresa(cini mi se da ovaj Paradigm ima pool od 192.168.1.64-
Vrati se na Ubuntu i kucaj(predpostavimo da XP ima 192.168.1.64 IP adrsu): sudo ifconfig eth0 192.168.1.65
sudo route add default gw 192.168.1.1
sudo gedit /etc/resolv.conf i ubaci sljedece: nameserver 195.222.32.10 , sacuvaj
ping google.ba

Super radi… mada prvo nisam mogla ubaciti ovu posljednju ip adresu. skontala sam onda da mogu u “manual network configuration” ( zamisli, manuelno…) upisati tu ip adresu.
puno hvala za pomoc. happy
