 |
|
I have a problem with wired network. I use gnome with ~amd64. If I plug in the cable, everything seems to work well, networkmanager connect with dhcp but I cannot ping any ip. Wireless works normally. If I stop networkmanager manually here is what happens
| Code: |
ifconfig wlan0 down
ifconfig eth0 down
ifconfig eth0 up
ifconfig
|
gives
| Code: |
eth0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
ether 00:1d:09:39:8d:58 txqueuelen 1000 (Ethernet)
RX packets 398 bytes 58731 (57.3 KiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 297 bytes 26950 (26.3 KiB)
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

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

then
gives
| 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

is this ok? I think so.
now gives
| Code: |

but internet does not work
| Code: |
ping 74.125.232.127
|
gives
| Code: |

Here is /etc/conf.d/net
| Code: |

The wireless network works perfectly. Any idea? |

waitwaitwait...
With networkmanager set up, do you get an IP address? The other posting did not get an ip address which is weird, seeming some possible configuration problem with the dhcp server or configuration into the dhcp client... it seems to be a very unique problem...
Then, if you do this finagling with it after disabling networkmanager, what is your routing table like? Did you get a default route?
Are you using ipv4 or ipv6?
Are you using gnome3 (I'm not, so I don't know about gnome3)
On my gnome2 Networkmanager machines it will automatically notice that eth0 is plugged in and DHCP an ip address. I do not use ipv6 so that's another thing I don't know.

| I get an IP with networkmanager, but with the same results. I use ipv4, but I suspect that the problem can be related to ipv6, but I do not know anything about this stuff. I use GNOME 3. |

What do you get if you traceroute out?
Is the default route correct?
Can you ping hardware on your LAN?
