[gentoo-user] No connection to the internet after update of today

[Hartmut Figge]

Greetings,

after 'emerge --sync' followed by 'emerge -uDN world' i have no longer a
connection to the internet. At the moment i am using an older Gentoo on
another partition of the same machine. The real Gentoo is mounted and i
can access it to answer questions.

I have now udev-197 which told me

So i have build a new kernel. The only difference is CONFIG_DEVTMPFS=y.
No problem so far with the horrible udev-197 *g*.

Here is what happens when i try to manually start ppp.

Really? I'm thinking this is udev not assigning eth0 to your network card.

What to do?

Tell us more about how you connect to the internet.

Most people here will be using an ethernet network in which eth0 is wired to a router. I have not used ppp since I disposed of my 56k pew-pew-eep-eep dial-up modem. If you're using PPPoE then you need to tell us about it, not assume we can read your mind.

Stroller.

I have now set the line length to 80, because the output of some routines would
be too difficult to read with a length of 72 without editing.

Hm. My persistent-net.rules still exists, has not changed and the new method of
naming network interfaces should be disabled by default.

Yes. :-D

I do not use a router. I need pppoe for the ADSL-Modem required by my ISP. On my
old Gentoo, which i am now using and which has the same configuration, i get

hafi@i5 ~ $ route
Kernel IP routing table

The configuration is done in /etc/conf.d/net, which i have posted above. In
syslog of the defunct Gentoo i find regarding ppp:

On the currently used old Gentoo syslog says:

I will give more information once i know waht will be needed. ;)

And you are right. I could get PADO packets on eth1. Modifying
/etc/conf.d/net gave me back the internet but eliminated my LAN. Hrm.

Well, now i can look for a real solution. Thanks for answering.
