duplex mismatch? czyli ze co?



Interfejs jest na auto i faktycznie na innej lokalizacji nie mam collisions ani deferred a tu sa hmm ....

wszystko pięknie... zainstalowalem sterownik karty sieciowej przez modconf, w pliku /etc/network.interfaces dopisalem:
auto eth0
iface eth0 inet dhcp wydalem polecenie dhclient eth0, popracowal popracował i wyskoczylo:

eth0      Link encap:UNSPEC  HWaddr 00-10-DC-00-00-79-57-8D-00-00-00-00-00-00-00-00

          collisions:0 txqueuelen:0
          RX bytes:792 (792.0 b)  TX bytes:792 (792.0 b) wnioskuje ze jest cos nie tak... tak jak w temacie łącze sie przez router...

PS. wkoncu jestesmy w temacie :)

aha... i dlaczego nie dziala mi polecenie:

lspci|grep Ethernet

??



bt ~ # echo 1 > /proc/sys/net/ipv4/ip_forward

Dalej cos nie chce pojsc:confused: hmm a te ip inet addr.192.168.1.197 pokazuje moje IP czy IP AP do ktorego aktualnie jestem podlaczony?Bo jak to moje ip to wszystko jasne:):)




  OK podałeś :

Coś jakby lepiej, już mamy eth0.
Ale co z konfiguracją przez drakconnect i nasze ulubione noapic i nolapic w lilo, które podałem jak wprowadzić w trybie graficznym.

@ marmal,
No popatrz ludzie się uczą obsługi forum ;)
