 Posted: Wed Jan 18, 2017 5:43 pm Post subject: Error start network |
 |
|
After reboot:
| Code: |
* Bringing down interface eth0
* Stopping netplug on eth0 ... [ ok ]
RTNETLINK answers: No such file or directory
Error talking to the kernel
* Bringing up interface eth0
* Starting netplug on eth0 ... [ ok ]
* Backgrounding ...
* Error: net.eth0 has not started |
Over time - networking started
Idea? |

Are you at all having eth0 or does it get renamed by udev rules?
You could simply test with ls -al /sys/class/net/ |

I have two network interfaces. Both run with an error at system start
net.eth0 and net.enp1s6
| Code: | lrwxrwxrwx 1 root root 0 янв 19 2017 enp1s6 -> ../../devices/pci0000:00/0000:00:08.0/0000:01:06.0/net/enp1s6
lrwxrwxrwx 1 root root 0 янв 19 2017 eth0 -> ../../devices/pci0000:00/0000:00:0a.0/net/eth0
lrwxrwxrwx 1 root root 0 янв 19 2017 lo -> ../../devices/virtual/net/lo |
lspci
| Code: |
00:0a.0 Ethernet controller: NVIDIA Corporation MCP77 Ethernet (rev a2)
01:06.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8100/8101L/8139 PCI Fast Ethernet Adapter (rev 10) |
/etc/conf.d/net
| Code: | modules_eth0="netplugd"
config_eth0="XX.XX.XX.XX netmask 255.255.255.240 brd XX.XX.XX.XX" <== secret
routes_eth0="default gw XX.XX.XX.XX"
dns_servers_eth0="193.238.131.93 193.238.131.65"
dns_search_eth0="academ.org"
dns_domain_eth0="academ.org"
modules_enp1s6="netplug"
config_enp1s6="192.168.50.1 netmask 255.255.255.252"
routes_enp1s6="default via 192.168.50.1" |
The problem is probably in the course of the year there, and only at rare reboot. Before that 9 years without any problems |

Same here, on multiple machines.
It should depend on me (some kernel module that I miss, or so). But I really don't know where to search for.

Oschtan,
| Code: | | 00:0a.0 Ethernet controller: NVIDIA Corporation MCP77 Ethernet (rev a2) |
That needs the | Code: | │ │ [*] NVIDIA devices │ │
│ │ < > nForce Ethernet support (NEW) |
The kernel symbol is CONFIG_FORCEDETH.
I suspect that its already there as the kernel can see | Code: | | lrwxrwxrwx 1 root root 0 янв 19 2017 eth0 -> ../../devices/pci0000:00/0000:00:0a.0/net/eth0 |
Do you have the net.eth0 -> net.lo symbolic link in /etc/init.d/ ?

Hi.
Just in case, is it possible you simply made a typo?
| Code: |
modules_eth0="netplugd"
modules_enp1s6="netplug"
|

Not for me.
I've:
| lspci | grep Eth: | | 02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 09) |
The card can work with the r8169 kernel module as driver, but many people tell about oddities, so there's a manufacturer provided module net-misc/r8168.
I cannot appreciate differences.

Really no. My configuration is very very simple, now:
| /etc/conf.d/net: | modules_eth0="dhcpcd"
config_eth0="dhcp"
dhcpcd_eth0="--noipv4ll" |
I've the same card in all my four home computer, and everywhere I've the same message when I stop the service, not when I start it (the symlink to net.lo is there).
I don't have the same if I configure the network manually (ip addr... ip link.. or ifconfig... or dhcpcd....), so the issue is related to the openrc service.
Obviously, there's always my hand in the kernel configurations, so I suppose that I systematically miss something.
The message is still there.
Regards,
HUjuice

hujuice,
Thats a different card with a different problem. You may be missing a firmware patch. Look in dmesg for firmware loading issues if you use the kernel r8169 driver.
If you use out of kernel drivers, you get to keep all the pieces.
We see from Oschtans post
| Code: | lrwxrwxrwx 1 root root 0 янв 19 2017 enp1s6 -> ../../devices/pci0000:00/0000:00:08.0/0000:01:06.0/net/enp1s6
lrwxrwxrwx 1 root root 0 янв 19 2017 eth0 -> ../../devices/pci0000:00/0000:00:0a.0/net/eth0 |
and | Code: | 00:0a.0 Ethernet controller: NVIDIA Corporation MCP77 Ethernet (rev a2)
01:06.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8100/8101L/8139 PCI Fast Ethernet Adapter (rev 10) |
by matching the PCI addresses that eth0 is 0000:00:0a.0.
I notice now that there is a mix of kernel assigned interface names and udev names. That's probably a bad thing.
We would need to see dmesg to know.

It looks all right, NeddySeagoon.
Yes, my card is different, I don't have any firmware related message. Note that I have the same card on four computers and I tried the net-misc/r8168 only in one of them, but the error is present everywhere.
Yes, I renamed the card via udev, nothing more than this: https://wiki.gentoo.org/wiki/Handbook:AMD64/Networking/Advanced#Network_interface_naming
My complete dmesg is here: http://pastebin.com/P7DdKh4n
