Okay, no problems with pppoe (user-mode).
In the Tips&Tricks section of the forum there is this HOWTO for kernel-mode PPPoE . I followed the steps there but it doesn't work!
First problem: pppd segfaults.
| Code: |
# /etc/init.d/net.ppp0 start
Bring eth0 up... [ ok ] *
Bringing ppp0 up...
Plugin pppoe.so loaded.
PPPoE Plugin Initialized
/sbin/runscript.sh: line 526: 4138 Segmentation fault /usr/sbin/pppd
${CMD_LINE} ${MODEMPORT} ${LINESPEED} ipparam ${IFACE} linkname ${IFACE} call
${PEER} noauth ${PPPOPTIONS} hide-password
[ ok ]
|
This is caused by an error in the posted HOWTO. The error is in /etc/conf.d/net.ppp0. When specifying PERSIST="yes", one must also specify RETRYTIMEOUT=n, where n is a number. So after putting a
in /etc/conf.d/net.ppp0, pppd segfaults no more.
On to the next problem.
After setting DEBUG=yes, I get the following messages:

No connection is etablished. Even after setting MTU=1492 and MRU=1492 in /etc/conf.d/net.ppp0, pppd still wants to increase MTU and MRU to 1500.
I found this message in the forum where firaX seems to have the same problem. He fixed it in using pppd-2.4.2b2. But the HOWTO in the forum doesn't use a beta pppd, but the usual stable one in Portage, i.e. net-dialup/ppp-2.4.1-r14, which AFAIS includes kernel-mode pppoe patches.
So does anyone has an idea what's wrong?
Thanks. |

firaX's message refers to Roaring Penguin's kernel-side support; the HOWTO doesn't use rp-pppoe. (I think.)

That's right but the problem looks similar.
Anyhow I got it working. I used the dsl mini-howto from gentoo.de. The big difference is that there are much more parameters with which pppd get called. So I guess my problem was that some madatory parameter for pppd was not defined.
I still get warnings "Couldn't increase MTU to 1500.", even through I define a smaller MTU value, but it looks like everyone using kernel mode pppoe gets this. It seems to be a bug in pppd. |
