[gentoo-user] Brand new instalation - Network problem
Hi list, I`ve just installed a brand new gentoo amd64 and there is this problem: my Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168 PCI Express Gigabit Ethernet controller (rev 06) is recognized as *sit0* , but I can't get any IP Adress. dhcp takes long and doesn't get any result. dhcpcd doesn't work either. Even if I choose a manual address I cant ping other devices. When I used ifconfig, I got something like ipv6 over ipv4, but I will only need ipv4. So I disabled ipv6 USE flag, but I didn't change anything. The weird thing is that if I disable the IPV6 kernel support (manual configuration btw), the network interface (sit0) desappears! When I reboot the system using a usb botable Ubuntu everything works fine, using the same hardware/infrastructure. I have no idea what is going on here, so, please, send me some links.

RTL8111/8168 PCI Express Gigabit Ethernet controller (rev 06) is recognized as sit0 , but I can't get any IP Adress. sit0 is completely unrelated, it is an IPv6 tunnel device. You need to compile the r8169 driver. Make sure CONFIG_R8169=m or y in your kernel config and try again (modprobe r8169). I have a Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 06), pci id 10ec:8168 on my motherboard and it works fine with the R8169 driver on kernel 3.10.9 (and has been working since at least the 3.4 series, which was when I installed this system) dhcp takes long and doesn't get any result. dhcpcd doesn't work either.

RTL8111/8168 PCI Express Gigabit Ethernet controller (rev 06) is recognized as *sit0* , but I can't get any IP Adress. sit0 is a virtual adapter for 6to4, an IPv6 transition mechanism, not a real Ethernet adapter. dhcp takes long and doesn't get any result. dhcpcd doesn't work either. Even if I choose a manual address I cant ping other devices. Since sit0 isn't a real adapter, it isn't actually your network card, so it isn't connected to anything.

You need to make sure the driver for your network adapter is compiled in to the kernel. I believe for your card, that would be CONFIG_R8169: Device Drivers --- [*] Network device support --- [*] Ethernet driver support --- [*] Realtek devices * Realtek 8169 gigabit ethernet support -- ♫Dustin http://dustin.hatch.name/

When I reboot the system using a usb botable Ubuntu everything works fine, using the same hardware/infrastructure. sit0 is used for ipv6 tunneling (6to4), it is not a physical interface While you're in the Ubuntu environment, issue lspci -k to see which kernel driver your ethernet device uses. It is R8169 which is provided by: Symbol: R8169 [=y] Type : tristate Prompt: Realtek 8169 gigabit ethernet support Location: - Device Drivers - Network device support (NETDEVICES [=y]) - Ethernet driver support (ETHERNET [=y]) - Realtek devices (NET_VENDOR_REALTEK [=y]) The Gentoo Handbook has the following Networking section http://www.gentoo.org/doc/en/handbook/handbook-amd64.xml?part=1chap=8#doc_chap2 which tells you what to do.

Thank you all, Hi João, Let's do some basic troubleshooting. look at the output of the following commands # lspci # dmesg | grep -b2 -a2 -i ethernet # lsmod This will hopefully help us determine if the correct driver is loaded.

2013/10/26 João Matos jaon...@gmail.com Hi João, Let's do some basic troubleshooting. look at the output of the following commands # lspci [...] 02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 06) # dmesg | grep -b2 -a2 -i ethernet [system, not chroot environment] 37800-[0.959789] e1000: Copyright (c) 1999-2006 Intel Corporation. 37865-[0.959836] sky2: driver version 1.30 37906:[0.959959] r8169 Gigabit Ethernet driver 2.3LK-NAPI loaded 37969-[0.960183] r8169 :02:00.0: irq 41 for MSI/MSI-X 38025-[0.960346] r8169 :02:00.0 eth0: RTL8168evl/8111evl at 0xc9628000, 90:2b:34:fb:4e:f9, XID 0c900800 IRQ 41 # lsmod There is something really strange here! These 5 lines is everything that I got when I run lsmod. The module is compiled (.conf attached) but, even if I tape modprobe r8169 the output doesn't change. berore I configure the kernel I've run make localmodconfig, but I don't think I would create any problem since I've used it some times before. Maybe it is not module. I compile it in kernel itself. The lines: Module Size Used by sit12439 0 ip_tunnel 11548 1 sit tunnel4 2165 1 sit ipv6 279632 15 sit This will hopefully help us determine if the correct driver is loaded. -- João Neto Linux User #461527 http://br.linkedin.com/pub/jo%C3%A3o-de-matos/7/316/552 Problem solved! Just a misunderstanding. At the beginning the module really wasn`t compilled into the kernel, but, when I did it, I was already assuming that the name was sit0. Everything is working fine with enp2s0. Thank you all. -- João Neto Linux User #461527 http://br.linkedin.com/pub/jo%C3%A3o-de-matos/7/316/552
