Hi.
I'm trying to setup a PPPoE in a Linux-From-Scratch system based on an old SuSE.
Things seem to work, but although i use the options `usepeerdns`
and `defaultroute`, pppd does not update the routing table nor
the resolv.conf.
By looking at resolv.conf it sais:
# Modified_by: dhcpcd
search lan
nameserver 10.0.0.138
and the fact that the routing table is:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
62.103.129.27 * 255.255.255.255 UH 0 0 0 ppp0
10.0.0.0 * 255.255.255.0 U 0 0 0 eth0
link-local * 255.255.0.0 U 0 0 0 eth0
loopback * 255.0.0.0 U 0 0 0 lo
default 10.0.0.138 0.0.0.0 UG 0 0 0 eth0
I have to suppose that somebody else has setup eth0 to be the default
gateway (maybe it's the distribution's LFS was built upon, ip-up scripts).
ifconfig is:
eth0 Link encap:Ethernet HWaddr 00:90:F5:47:77:3B
inet addr:10.0.0.1 Bcast:10.0.0.255 Mask:255.255.255.0

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

ppp0 Link encap:Point-to-Point Protocol

TX packets:3 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:3
RX bytes:290 (290.0 b) TX bytes:54 (54.0 b)
So I kill pppd and say:
route del default
and re-run pppd:
This time I have the routing table:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
62.103.129.27 * 255.255.255.255 UH 0 0 0 ppp0
10.0.0.0 * 255.255.255.0 U 0 0 0 eth0
link-local * 255.255.0.0 U 0 0 0 eth0
loopback * 255.0.0.0 U 0 0 0 lo
default * 0.0.0.0 U 0 0 0 ppp0
But unfortunately, the network is unreachable. I try to connect
to hosts by IP address, but I'm not getting any packets.
Finally the messages of pppd with `debug` (before removing the default route):
Plugin rp-pppoe.so loaded.
RP-PPPoE plugin version 3.3 compiled against pppd 2.4.4

How can I debug this further?
Any help will be vastly appreciated.
