 Posted: Wed Sep 24, 2014 3:21 am Post subject: [solved?] missing enp4s0 and replaced with sit0 |
 |
|
I reinstalled gentoo and a problem I ran into was that my enp4s0 ethernet interface was gone. In place of it was sit0.
I tried running a # dhcpcd sit0 but it didn't give me network.
I research around and found out it was some ipv6to4 or something.
But I don't know how to get rid of it and how to get my eth0 or enp4s0 back. :/

Three questions:
- What type is your card? Are you sure that the required drivers are enabled in the kernel?
- What is your udev version? It is possible that your reinstall settled on an older udev that does not use the persistent naming.
- If you have an updated udev did you disable the persistent naming in the kernel?

- I think I have the correct driver enabled. Because I don't have network and I didn't install pciutils during installation, I can't be for sure.
But from the last time I installed it, I remembered it was a Realtek 8169 gigabyte ethernet port and I have it enabled in my kernel
- I have sys-fs/udev-216
- I'm not sure what I have to enable for persistent naming. Please help me with this |

CONFIG_R8169=y ?
You could test with

Persistent naming vs. predictable naming would turn irrelevant when you moved to using pure dhcpcd instead of Gentoo net.* scripts.

I booted into the livecd, chrooted and installed lspci.
I did a # lspci -k and it was using the correct driver
and yes, I am using dhcpcd
But I still don't have an eth0/enp4s0 interface
When I do ifconfig -a -v I only have the lo: and sit0 interface
I want to know how to disable this sit0 interface and enable back my enp4s0 interface[/code]
I'm sorry for not printing actual code because I cant copy it |

It's a tunnelling interface.
Check for your loaded modules with 'lsmod'. If you have ipv6 loaded - blacklist it.
If you have ipv6 options enabled in kernel - disable them all and rebuild kernel.
Added:
Check for 'sit' module in lsmod output. If you have such a module, blacklist it also. |

I'm using a vmlinuz with a genkernel initramfs.
When I did # lsmod It showed that I had nothing loaded.
I went into my kernel and searched ipv6. Disabled all of them and rebuilt my kernel.
Rebooted and I still have my sit0 interface. I still don't have my enp4s0 interface for ethernet :/? |

It is strange enough that you have no any modules loaded... Hmm.
Can you post your .config ? |

The device should have been set up by udev. Are you having these 2 files? | Code: | $ cat /lib/udev/rules.d/75-net-description.rules
# do not edit this file, it will be overwritten on update
ACTION=="remove", GOTO="net_end"
SUBSYSTEM!="net", GOTO="net_end"
IMPORT{builtin}="net_id"
SUBSYSTEMS=="usb", IMPORT{builtin}="usb_id", IMPORT{builtin}="hwdb --subsystem=usb"
SUBSYSTEMS=="usb", GOTO="net_end"
SUBSYSTEMS=="pci", ENV{ID_BUS}="pci", ENV{ID_VENDOR_ID}="$attr{vendor}", ENV{ID_MODEL_ID}="$attr{device}"
SUBSYSTEMS=="pci", IMPORT{builtin}="hwdb --subsystem=pci"
LABEL="net_end" |
| Code: | $ cat /lib/udev/rules.d/80-net-setup-link.rules
# do not edit this file, it will be overwritten on update
SUBSYSTEM!="net", GOTO="net_setup_link_end"
IMPORT{builtin}="path_id"
ACTION=="move", IMPORT{db}="ID_NET_DRIVER"
ACTION!="add", GOTO="net_setup_link_end"
IMPORT{builtin}="net_setup_link"
NAME=="", ENV{ID_NET_NAME}!="", NAME="$env{ID_NET_NAME}"
LABEL="net_setup_link_end" |
Then the device should be in /sys/class/net/ |

I got it fixed somehow :/
I just reinstalled gentoo again with a bit different .config and no initramfs.
I now have enp4s0 and lo as my interfaces
I did not compile my kernel with ipv6 this time.
Maybe it was because of the time I installed Gentoo?
I installed it yesterday and there were a bunch of server movements during that time. :/ |

| No, the difference is that you configured your kernel correctly this time. |
