 |
|
Here's the deal: when configured from the install media, my network connection works just fine and dandy.
However, after the reboot and inside the chrooted environment it doesn't work.
I'd even reverted to rp-pppoe instead of pppd, which I haven't used up till now, so I'd thought there was a configuration error.
(Oh, yes, I'm using it for ADSL... it just times out.)
No good.
Then I remembered having a similar problem once and being told there must be something wrong with my kernel config... nope, forcedeth is compiled in the kernel.
Besides, chroot uses the kernel from the CD, not the one I compiled... so what am I doing wrong?
What am I missing?
TIA

| Did you copy /etc/resolv.conf into the chroot? |

I don't recall doing it, but I checked just now: they are identical.
So either I'd copied it or it was generated when I did the pppoe-setup or something... it only contains two nameserver lines.

If you've mounted /dev and /proc in your chroot as well then I can't explain it.
Are you positive the connection is working outside the chroot? |

I had the same issue, and it was because I'm often too lazy to mount /dev and /proc, so just run dhcpcd from inside the chrooted environment and it should pick up a connection.

I will try that, but what about when I reboot?
It is not a chroot then, and it doesn't work either...

Just checked... mounted proc and dev all right (-t proc none /mnt/gentoo/proc, -o bind /dev /mnt/gentoo/dev), chrooted, stopped the connection from the outside of chroot.
I don't even have dhcpd inside chroot; I don't need it.
Anyway, I tried starting pppoe again, and it timed out yet again, so this is not it.

Hello, you will need to configure /etc/conf.d/net to use the DHCP.
Also, you will need to install dhcpcd.
| Code: |
# nano /etc/conf.d/net
config_eth0 = "dhcp"
# emerge -pv dhcpcd
# emerge -v dhcpcd
|

DHCP is of no use to me...
I finally found out the problem: ppp really worked, but didn't get any DNS info. I can't fathom why.
When I tried running rp-pppoe, it couldn't connect because of ppp.
Since I couldn't find where to add the DNS info for ppp (rp-pppoe uses resolv normally), I switched back to rp-pppoe.
I haven't tested it thoroughly yet, but it should work now.
Now all that remains to be done are sound and X... when I get home in a day or so.

It is your DHCP client's job to obtain the DNS info. |

Back again...
I don't think my ISP sends out any DHCP information; I've always had to specify the DNS manually.
