 |
|
Salve a tutti, ho un problema con la connessione wired. Uso ~amd64 e quando attacco il cavo networkmanager si collega normalmente, con dhcp. Tuttavia non riesco a visitare nessuna pagina. La rete wireless funziona perfettamente. ifconfig da come output il seguente
| Code: |
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.150.69 netmask 255.255.255.0 broadcast 192.168.150.255

| Che sia un problema di impostazione di DNS? Hai provato a pingare un qualche IP tipo 74.125.232.127 (google.it)? |

Sì, ho provato, e non funziona. Il dns mi pare a posto in ogni caso. Sono davvero perplesso, tutto pare funzionare normalmente. Se stoppo networkmanager e faccio tutto a mano non dà nessun errore
| Code: |
ifconfig wlan0 down
ifconfig eth0 down
ifconfig eth0 up
ifconfig
|
dà come output
| Code: |
eth0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
ether 00:1d:09:39:8d:58 txqueuelen 1000 (Ethernet)

TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

lo: flags=73<UP,LOOPBACK,RUNNING> mtu 16436
inet 127.0.0.1 netmask 255.0.0.0
inet6 ::1 prefixlen 128 scopeid 0x10<host>
loop txqueuelen 0 (Local Loopback)
RX packets 1047 bytes 90210 (88.0 KiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 1047 bytes 90210 (88.0 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

se poi do
dà
| Code: |
dhcpcd[3381]: version 5.5.6 starting
dhcpcd[3381]: eth0: sending IPv6 Router Solicitation
dhcpcd[3381]: eth0: rebinding lease of 192.168.150.69

che mi pare normale
adesso restituisce
| Code: |

ma internet non va
| Code: |
ping 74.125.232.127
|
restituisce
| Code: |
PING 74.125.232.127 (74.125.232.127) 56(84) bytes of data.
^C

giusto per gradire, /etc/conf.d/net è il seguente
| Code: |
#Generated by NetworkManager
###### Global Configuration ######
###### Connection Configuration ######
#----------------------------------
mac_eduroam="00:1C:BF:D3:53:28"
config_eduroam="
dhcp
dhcp6
"
auto_eduroam="true"
enable_ipv6_eduroam="true"
#----------------------------------
mac_eth0="00:1D:09:39:8D:58"
enable_ipv6_eth0="true"
auto_eth0="true"
config_eth0="dhcp dhcp6"

e la rete wireless funziona tranquillamente. Proprio non capisco! |

Sicuramente un tempo andava, ma era da po' che non usavo più il cavo, quindi non saprei dire a che punto ha smesso di funzionare. Invece route quando uso la rete wireless dà
| Code: |
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default 192.168.151.2 0.0.0.0 UG 0 0 0 wlan0
loopback localhost 255.0.0.0 UG 0 0 0 lo
192.168.151.0 * 255.255.255.0 U 2 0 0 wlan0
|
mentre quando uso quella wired (che non funziona) resta lì a pensare
| Code: |
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
^C
|
Il che suggerisce che in effetti qualcosa che non va c'è... |

Chiedo perdono, bastava farlo pensare un po' di più
| Code: |
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default 192.168.150.1 0.0.0.0 UG 0 0 0 eth0
loopback localhost 255.0.0.0 UG 0 0 0 lo
192.168.150.0 * 255.255.255.0 U 1 0 0 eth0

| E' corretto il gateway che ti restituisce route quando usi il cavo? Riesci a pingarlo? Hai provato disattivando NetworkManager? |
