Can't start enp2s0(dhcpcd waiting for carrier error)[SOLVED]

[rudregues]

When I boot the system, use /etc/init.d/net.enp2s0 start or dhcpcd enp2s0 commands, I've that error:

[chithanh]

If you suspect that dhcpcd's carrier detection misdetects, you can disable it in your network config.

[rudregues]

That procedure elimated the initial error, but network doesn't work yet.
During the boot, I can see some bad messages (not all because it's too quick for me), but I can see some lines with "Network unreachable" expression.

By dhcpcd manual:

[chithanh]

When you boot from livecd, does your network work there? If yes, then possibly there is a problem introduced in the kernel version that your install uses.

You can compare the output of

[TomWij]

Please provide `lspci -k` output of both your Sabayon and the LiveCD so we can see the devices and more easily compare the lists, that way we don't need to interpret what all the module names are and can instead look at the relevant devices.

Ok, here the result from a Xubuntu LiveUSB from the lspci -k command

[TomWij]

Eh, I think the Gentoo LiveCD was meant but I'm not sure why that was suggested, you're already past that phase; so, I think you might want to do it in your Gentoo install (real boot, no chroot) instead. That way we can compare it between your Sabayon install and Gentoo install, it was fine that you posted the Xubuntu LiveUSB, we can still use that as a cross-verification then.

So, yes, please reboot into the Gentoo install and capture its output.

Ok, output of lspci -k booting from my Gentoo install:

Apart from a different description on the LiveCD, the Ethernet and Network controller look the same for all three. So, that's not where the issue lies.

net-setup is in the app-misc/livecd-tools package, but that might not solve the issue; if you however want to try static IP so you can at least work on your Gentoo instead, that might be an option to consider. Although you could configure a static IP in /etc/conf.d/net instead so you don't need the extra tools, similarly `ifconfig enp2s0 down IP/24 up` (replace IP by your IP) would do the same manually.

[rudregues]

Well, I've added the two last lines following the handbook in /etc/conf.d/net (I don't know what it means, I just copy and paste)

[TomWij]

Copying and pasting never works when trying to do something specific; you can't use wpa_supplicant (for wireless networks) for ethernet (wired network) so you will want to remove that line, and at the bottom you will want to properly set the IPs in the config and routes variables. Since you copy pasted them, I assume you might have not properly set them yet.

Can you also post `dmesg`? Just in case we're missing some warning there...

[rudregues]

Jaglover, here is the output of ethtool enp2s0 command

[TomWij]

[Jaglover]

How it can connect in Sabayon is mystery for me, below is the output of ethtool as it should be.

1) Someone here knows Ceni? http://manual.aptosid.com/en/inet-ceni-en.htm#netcardconfig
That program seems perfect to help me with this, but I can't find any ebuild or source code to compile and install. And here the user Bumbl sad:

[rudregues]

Well, I tried a bunch of commands with networkmanager and wicd

[TomWij]

Start the dbus daemon (using the init script) and at least add it to your default runlevel.

[rudregues]

I ran sudo ethtool eth0 in Xubuntu LiveUSB and here is the output:
