evo route -n:

0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth0

ok, sad uredi /etc/network/interfaces da izgledaju ovako;

auto lo
iface lo inet loopback

allow-hotplug eth0
iface eth0 inet dhcp
mtu 1400

allow-hotplug eth1
iface eth1 inet static
address 192.168.10.1
netmask 255.255.255.0
network 192.168.10.0
broadcast 192.168.10.255

saveaj file, nakon toga napravi sudo /etc/init.d/networking restart.
u tom trenutku ces vjerovatno izgubiti konekciju na net koja ce se vratiti kad napravis dhclient eth0, nisam siguran da li ti ispred toga treba sudo ili ne, ako ne radi bez sudo, napravi sa sudo.

konekcija se ne vraća

evo me opet na nerbooku.

kada kliknem na ikonu kaže: device is unmanaged

vidim u terminalu da kaže : renewal in 39987 secons

znači li to da će proraditi nakon tih sekundi?

jeb* ikonu..

daj upisi;

- ping google.com
- cat /etc/network/interfaces
- ifconfig
- route -n
- dhclient eth0

i sve copy-pasetaj tu.

sudo dhclient eth0

problem je opet u mtu-u, ovo nije upalilo..

khm, da sad ne istrazujemo i pisemo razne djdije, rijesiti cemo to na quick&dirty nacin, nije bas po ps-u, ali ce raditi, ali daj mi reci da li ti radi ifconfig eth0 mtu 1400 bez sudo?

upisao sam ifconfig eth0 mtu 1400
i kaže OPERATION NOT PERMITTED. znači ne radi , pretpostavljam

i onda sam upisao sudo ifconfig eth0 mtu 1400 tako da lakše baratam.

i radi

a ikona je i dalje bezveze "device is unmanaged"

u /etc/network/interfaces zamijeni mtu 1400 sa pre-up /sbin/ifconfig eth0 mtu 1400, testirao sam, ovo radi.

nakon toga rebootaj komp.

oprosti, gdje je taj /etc/network/interfaces ?

znam , možda zvuči vrlo glupo, ali meni je puno glava brojki i slova i niš ne kužim.

a u međuvremenu sam probao ovo , i to ne radi:

niksasrsen@niksasrsen-laptop ~ $ pre-up /sbin/ifconfig eth0 mtu 1400
bash: pre-up: command not found
niksasrsen@niksasrsen-laptop ~ $ sudo pre-up /sbin/ifconfig eth0 mtu 1400
