 Posted: Fri Jul 08, 2011 8:54 pm Post subject: [INVALID] Network suddently stopped working |
 |
|
My main computer stopped connecting properly to the network today (after a cold restart).
Eth0 is still up and has it's ip - the route is correct. I just can't ping any network system but itself.
I changed the ethernet cable to another one which I'm using on my notebook - its working (the cable, not the problem).
The kernel is doing fine since a long time, so I have no clue what's causing this issue.
no log I found has any useful information.
lspci shows: | Code: | | 00:14:0 Bridge: nVidiaCorporation MCP51 Ethernet Controller (rev a3) |
uname -r shows: 2.6.38-gentoo-r7
I restarted forcedeth it seems to find everything, last line:
restarting /etc/init.d/net.eth0 or network doesn't help at all.
I have no clue where to search for the problem.
btw: ~x86
Oh and till yesterday I was pretty up2date (I only masked kernels > 2.6.3 .

fixed ip - and since only 2 pcs are connected to the router (and there is no restriction in it) the ip should work (like it worked for years now). |

| Code: | nameserver 192.168.1.1
search 192.168.1.1 |
and I don't get why 8.8.8.8 should be a reachable ip (it's not) |

it's a google public dns server and should be reachable
| Code: | # ping -c 2 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
64 bytes from 8.8.8.8: icmp_req=1 ttl=48 time=46.7 ms
64 bytes from 8.8.8.8: icmp_req=2 ttl=48 time=46.2 ms |
summary: you can ping your router but you can't ping through the router
if the laptop pings through now but this machine does not I'd suspect a firewall or nat problem on the router.

Where did I say I can ping my router?
I can't.
Oh and my laptop is indeed able to ping 8.8.8.8 |

yes
edit:
before you ask me what ifconfig shows:
protokoll: ethernet
hwaddr: bl:ah:bl:ub:wh:at:ev:er
inet Addr: 192.168.1.103
BCast: 192.168.1.255
Mask: 255.255.255.0
and I'm to lazy to copy the rest. Oh maybe that could be usefull: "RX packets: alot; errors: 0 dropped: 0 overruns:0 frame:0"

change ip to 192.168.1.17 in /etc/conf.d/net then | Code: | | /etc/init.d/net.eth0 restart |
entries in /etc/conf.d/net no longer look like ( "blah" ) but just like "blah" ?

my conf.d/net looked like:
| Code: | | config_eth0=( "192.168.1.103 netmask ....." ) |
should I change that to:
| Code: | | config_eth= "192.168.1.103 netm......" |
?
Changing to only .1.17 didn't fixed anything
EDIT: I changed it to without the (s didn't changed anything.
Btw I though this config file only changes ip adress and routes - why should that be fixed? It looks quite correct to me how it is - the problem must be somewhere else (I just have no clue where). |

I found something.
dmesg is now filled with some lines from forcedeth.
there are a lot of lines like:
forcedeth 0000:00:14:0: eth0: 3Bit 8Bit 8Bit 8Bitt // 3*8Bit // 3*8Bit
lines, after that:
| Code: | Got tx_timeout. irq: 00000020
Ring at 30928000
Dumping tx registers |
After that a few lines looking like I would say a tx registers dump.
After that again "Dumping tx ring" and the lines from the start go on.
those are repeating after a few time. |

Here nothing like that:
dmesg | grep -i forcedeth

(two nics here}
when you changed the ip and restarted the NIC did ifconfig change, ip? tx errors? rx errors?
have any friends who can loan a card or a usb dongle?
openrc required the new format,

the ip changed when I restarted net.eth0, I know that what I posted isn't normal. I got no tx or rx errors and I don't know anyone with a networkcard which isn't integrated into the mainboard |

net.eth0 is in runlevel default
next:
eth0 is started at runlevel fine and is configured fine (since it doesn't work neither if I configure it per hand) /etc/init.d/net.eth0 (re)start per hand does NOT work
that issue is not related to my problem
openrc 0.8.3-r1 was last emerged on 29.06.2011 - the network worked until 08.07.2001, I shutdown and start my system every day - so it worked at least 8 times after that happened. |

I just did a cold restart and it worked again.
I'm marking this as invalid. |
