DHCP nedava adresu, staticka IP funguje

[Wors]

Zdravim,
uz asi tretim dnem prochazim fora o ubuntu kvuli problemum se siti a teprve dnes mi zacala fungovat.
Bohuzel ale jen na staticke IP a mam strach, ze to muze byt casem na zavadu.

Kdyz jeste nic nefungovalo, zkousel jsem podle fora vypsat par prikazu:

Pak jsem zkusil route a priradit default gw.
Mam pripojeni takove, ze wifi antenou na strese chytam signal z vysilace kamarada, ktery ma ADSL. Z anteny je napojeny Edimax, z nej switch a pak me PC.

Nakonec me napadlo podivat se do Windows, co mi bylo vse prideleno a pri prikazu ipconfig mi vyjelo:

Kód: [Vybrat]

Konfigurace site Ethernet Pripojeni k siti:
        Pripona DNS podle pripojeni . . . . . . domain
        Adresa IP                        . . . . . . 192.168.50.37
        Maska podsite                  . . . . . . 255.255.255.0
        Vychozi brana                  . . . . . . 192.168.50.1

Od te doby ping fungoval...

Co mam udelat, abych mel IP prirazenou od DHCP automaticky? Abych nemusel mit IP staticky. Nevim, jestli mam vzdy stejnou IP a kdyby se mi nahodou nekdy zmenila, mohlo by dojit ke kolizi v siti.

Mam to nechat tak, nebo to jde nejak vyresit?

Predem diky za odpoved

Zkontrolujte, zda MAC adresa pod Windows je shodná s tou v Linuxu.
Zkuste také dhcpecko probrat manualne:

Kód: [Vybrat]

sudo ifdown eth0
sudo dhclient eth0


[truhlik]

Nemelo byt byt v /etc/network/interfaces

Kód: [Vybrat]

auto eth0
iface eth0 inet dhcp


[Petr Merlin Vaněček]

Luboš "truhlik" Truhlář: ne, on to NM totiž stejně ignoruje ...
Což vůbec není pěkné.

[Petr Merlin Vaněček]

No vida ho potvoru

[Wors]

Tak jsem nasel nejake reseni, hned jak dorazim domu ho zkusim...

Kód: [Vybrat]

I've had exactly the same problem, however just found the solution:
In the Gusty Tribe 5 live installer, open a terminal:

$ sudo su
# rmmod forcedeth
# modprobe forcedeth msi=0 msix=0
# /etc/init.d/networking restart

Your network interfaces should come back up and actually work now :-)

Doufam, ze v tom neni nejaky zadrhel, kterym bych neco pokazil

EDIT:

Kód: [Vybrat]

I had the same problem with embedded nForce NVIDIA network controller.
The fix consisting in putting "options forcedeth msi=0 msix=0" in in the interface file (and then "sudo update-initramfs -u") worked for me as well.
thank you :)

[Wors]

Hmm, tak to nijak nepomohlo (

Kód: [Vybrat]

$ sudo su

s# rmmod forcedeth

# modprobe forcedeth msi=0 msix=0

# /etc/init.d/networking restart
 * Reconfiguring network interfaces...                                   [ OK ]

# ping 192.168.50.1
connect: Network is unreachable

# cat /etc/network/interfaces
auto lo
iface lo inet loopback


# update-initramfs -u
update-initramfs: Generating /boot/initrd.img-2.6.24-18-generic


Nepochytil jsem, co s tim :-(
Staticka IP mi prozatim funguje pri kazdem spusteni, tak se na to asi vybodnu, ale stve me, ze jsem nenasel reseni

[Petr Merlin Vaněček]

No bacha na věc - když to děláte ručně, musíte mít v /etc/network/interfaces i tu danou síťovku, pouze pokud to ponechávate na NM, tak tam být nemusí.
zkuste toto:

Kód: [Vybrat]

sudo modprobe -r forcedeth
sudo modprobe forcedeth msi=0 msix=0
dhclient eth0
ping 192.168.50.1


[Wors]

Zkusil jsem to, ackoli nevim v podstate co delam, coz je docela problem )
Bylo by to jednodussi, kdybych tomu rozumnel

[Petr Merlin Vaněček]

Co děláte?

Kód: [Vybrat]

sudo modprobe -r forcedeth
Odstraníte modul (ovladač) forcedeth ze těch zavedených

Kód: [Vybrat]

sudo modprobe forcedeth msi=0 msix=0
Ten samý modul zavedete s určitými parametry, ovladač od ovladače se liší

Kód: [Vybrat]

dhclient eth0
Řeknete DHCP klientovi, aby se na eth0 pokusil získat adresu ze serveru DHCP

Kód: [Vybrat]

ping 192.168.50.1
Pingujete bránu.

Bohužel stejně podle toho výpisu vidím, že žádný DHCP pack síťovka nedostala

[Wors]

Je normalni, ze to hleda na masce 255.255.255.255, kdyz ve winech mam automaticky 255.255.255.0?

Kód: [Vybrat]

DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 8

[Petr Merlin Vaněček]

Ano, to je zcela normální, protože se nejedná o masku, ale o označení všech subnetů v síti - na všechny možné existující bcasty - klient neví jakou adresu má server, musí se ptát všude.
