 |

It is PPPoE (ppp over ethernet)
Followed this: http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=4&chap=3
| Code: | ln -s /etc/init.d/net.lo /etc/init.d/net.ppp0
ln -s /etc/init.d/net.lo /etc/init.d/net.eth0
config_eth0=null (Specify your ethernet interface)
config_ppp0="ppp"
link_ppp0="eth0" (Specify your ethernet interface)
plugins_ppp0="pppoe"
username_ppp0='user'
password_ppp0='password'
pppd_ppp0="
noauth
defaultroute
usepeerdns
holdoff 3
child-timeout 60
lcp-echo-interval 15
lcp-echo-failure 3
noaccomp noccp nobsdcomp nodeflate nopcomp novj novjccomp"
rc_need_ppp0="net.eth0" |
But ifconfig doesn't show eth0 device, network is not starting, pppoe-start doesn't work. What can be the reason for this? |

| There are several possible reasons. What is the output of emerge --info ; ip l ; ip a? |

ip a or ip l displays a device named "enp2s0" or something like that. But eth0 is expected. /etc/init.d/net.lo is symlinkd to /etc/init.d/net.eth0 , /etc/init.d/net.eth0 start get error or not device found like error.
It is pppoe connection. So during pppoe-setup i had to type enp2s0 instead of eth0, then it worked.
Did this from quick install:
| Code: | livecd etc # cd init.d
livecd init.d # ln -s net.lo net.eth0
livecd init.d # cd ../conf.d
livecd conf.d # echo 'config_eth0="192.168.1.10 netmask 255.255.255.0 brd 192.168.1.255"' >> net
livecd conf.d # echo 'routes_eth0="default via 192.168.1.1"' >> net
livecd conf.d # echo 'hostname="myhostname"' > hostname
livecd conf.d # rc-update add net.eth0 default |
What can be the reason not having eth0 ? |

colag ... simply substitute eth0 for enp2s0 ...
| Code: | # rc-update del net.eth0 default
# rm /etc/init.d/net.eth0
# ln -s /etc/init.d/net.lo /etc/init.d/net.enp2s0
# sed -i.bak -e 's/eth0/enp2s0/g' /etc/conf.d/net
# rc-update add net.enp2s0 default |
best ... khay |

You might have omitted the driver for the network card. However, based on the device name provided, it is more likely that you installed a braindamaged version of udevd and did not tell it not to be stupid. It then renamed your device. |

enp2s0 = udev / systemd network interface persistent naming.
you can disable this by 1 inserting a udev rule to over ride the rule that is generating those names, or 2 run eudev instead. there are more options, like mdev or static dev but i dont know too much about those.
| Code: |
ln -s /dev/null /etc/udev/rules.d/80-net-name-slot.rules
