Ciao a tutti,
ho recentemente reinstallato Gentoo sul mio PC. Al riavvio non riconosce la scheda di rete pur caricando il driver corretto.


Da
Code:

ifconfig eth0

risulta
Code:

eth0: error fetching interface information: Device not found


Il kernel 3.8.13 riconosce l'interfaccia come:
[/code]
Code:

07:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168 PCI Express Gigabit Ethernet controller (rev 06)


Il modulo viene caricato

Code:

Module                  Size  Used by
r8169                  54864  0


Se server posto la configurazione del kernel.

Luciano.

La colpa è del nuovo udev.

http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames

Anche lasciando /etc/udev/rules.d vuoto non mi riesce di avere i vecchi nomi funzionanti.
Dovrebbe esserci modo di configurare i vecchi nomi definiti dal kernel se proprio ti servono ma non me lo sono posto il problema.

Grazie a entrambi per la dritta. In effetti il nome è tutt'altro 8O:

Code:

dummy0: flags=130<BROADCAST,NOARP>  mtu 1500
        ether 1e:26:33:a2:76:11  txqueuelen 0  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

enp7s0: flags=4098<BROADCAST,MULTICAST>  mtu 1500
        ether bc:5f:f4:0b:8d:67  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
        loop  txqueuelen 0  (Local Loopback)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

sit0: flags=128<NOARP>  mtu 1480
        sit  txqueuelen 0  (IPv6-in-IPv4)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0



cioè enp7s0 quindi ho risolto con il collegamento in /etc/init.d/
Code:

# ln -s net.lo net.enp7s0

Ora la rete c'è. :)

Luciano.

è quello, enp7s0 è il nome assegnato dal kernel. Cambia a seconda del driver che usi, e l'ultimo numero, a parità di driver, secondo l'ordine di caricamento (che in genere corrisponde alla posizione sul bus).

Non so se valga ancora, ma qualche tempo fa con il sistema ancora in test udev se trovava il file "80-net-name-slot.rules" in rules.d manteneva i vecchi nomi (indipendentemente dal contenuto del file).

Devi passare net.ifnames=0 come parametro al kernel.
