Post subject: | Rebuilt 5.5 no networking |
I have rebuilt my knoppmyth 5.5 backend due to new motherboard/processor/tuner. I performed a standard install. As a backend it is working except I cannot connect through ethernet outbound or inbound. Relevant information from the backend console ping -c 2 192.168.1.1 gives PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.

Does /etc/resolv.conf exist and if so, what are it's contents? |

eth0 might have been renamed and if it did then you would have to change to what that is. I had this happen on one of my machines so I use eth2 instead of eth0. $ dmesg | grep -i eth[0-9] [ 2.587137] e100: eth0: e100_probe: addr 0xfbfff000, irq 20, MAC addr 00:0c:f1:bc:3f:43 [ 32.765233] udev: renamed network interface eth0 to eth2 [ 33.334570] ADDRCONF(NETDEV_UP): eth2: link is not ready [ 33.336152] e100: eth2 NIC Link is Up 100 Mbps Full Duplex [ 33.336411] ADDRCONF(NETDEV_CHANGE): eth2: link becomes ready [ 43.448025] eth2: no IPv6 routers present |

Try running the networking script with the "reset and start over" option. I forget the details but a search through the forums should turn them up. Ah-ha... Code: /usr/sbin/netcardconfig --force

/etc/resolve.conf contains nameserver 192.168.1.1 but that should not be used anyway since I am doing a ping to the ip address dmesg|grep -i eth[0-9] returns eth0:RTL8168b/8111b at 0xf.......... IRQ 17 r8169: eth0: link up eth0: no IPv6 routers present NETDEV WATCHDOG: eth0: transmit timed out repeated doing netcardconfig ran through the configuration dialog. I used the following use DHCP broadcast <no> IP Address for eth0 192.168.1.4 Network Mask for eth0 255.255.255.0 Broadcast Address for eth0 192.168.1.255 Default Gateway 192.168.1.1 Nameserver(s) 192.168.1.1 the result was ifconfig eth0 192.168.1.4 netmask 255.255.255.0 broadcast 192.168.1.255 up route add default gw 192.168.1.1 SIOCADDRT: File exists auto lo eth0 Setting Nameserver in /etc/resolve.conf to 192.168.1.1 Done. Looks like the error is in SIOCADDRT. Found may results on a search but cannot yet find a match for the problem I am having. Any more ideas? |

Did you say you had new hardware? Actually I'll answer that one myself: yes you did. Have you tried other software with your new system? for example does the latest ubuntu work correctly? It could be a simple thing like the new hardware is not supported by the kernal in 5.5. I had this problem initially when I bought a new mobo (in sig) - upgrading to R6 sorted me right out as it's kernal is more up to date. |

steptow wrote: NETDEV WATCHDOG: eth0: transmit timed out That's your problem. I suggest you google "NETDEV WATCHDOG: eth0: transmit timed out".
repeated (Just a guess, but you might first try changing pnp OS settings in your BIOS if you have them.... I think this is an IRQ problem) Good luck, Allen |

Post subject: | LINHES supports the network adapter |
I installed LINHES on a new disk and networking works. So the problem is new hardware not recognized by Knoppmyth 5.5. Now I just have to upgrade everything. |
