 |
|
I need some help setting up PPPoE in gentoo, I´ll get right down to buisness 
I have emerged ppp and rp-ppp, I ran adsl-setup and specified my username/password and so on.
When I try to connect I get the error msg:
| Code: | Couldn't set tty to PPP discipline: Invalid argument
pppoe: read (asyncReadFromPPP): Session 43332: Input/output error
|
This is the output from #DEBUG=1 adsl-start

I have only compile PPPoE into the kernel, should be sufficient...
My net setup: Computer connected to a switch and from there to the modem via ethernet.
Any ideas?

Hmmmmm....
Well, that output there shows another error that might be hindering your (and our) quick
resolution to this problem:

Where is your 'messages' logfile? Have you emerged syslog-ng on this system?
Also, I notice you aren't loading any modules for your ethernet card. Does this mean you've
built the drivers into the kernel?
Let us know.

Yea, I all drivers are built into the kernel, I rarly build any modules almost everything I included in the kernel I use all the time so is there any reason
for building is as modules? faster? more stable?
And I have not emerged syslog, I use metalog instead. Seems strange that a log file would be the reason that I cant get a connection...?
Thanks for your answer! =)
Maybe I should mention that the ethernet interface works perfect!, but not with ppp =) |

*bump*
Info add...
I dont use /etc/conf.d/net OR /etc/conf.d/net.ppp0 for this connection I reccon It would work without since those are gentoo specific
the same with the start up script /etc/init.d/net ...
Correct me if I am wrong on this bit.. |

I have the same problem.
I can't provide DEBUG info because i'm on another computer atm.
I'm just wondering what that error means "couldn't set tty to PPP disciple".
Can anyone explain?

Actually, I was referring to what might have been put in the messages file from that one section of the output.
One thing I was wondering about was why it says:
| Code: | ---------------------------------------------
* The following section shows the pppd command we will invoke
pppd invocation
/usr/bin/setsid /usr/sbin/pppd pty '/usr/sbin/pppoe -p /var/run/-adsl.pid.pppoe -I eth0 -T 80 -U -m 1412 ' noipdefault noauth default-asyncmap defaultroute hide-password nodetach usepeerdns mtu 1492 mru 1492 noaccomp noccp nobsdcomp nodeflate nopcomp novj novjccomp user MY USERNAME TADDDAA TA DAAA!!! lcp-echo-interval 20 lcp-echo-failure 3 debug
--------------------------------------------- |
The 'pty' is the device the pppd daemon is trying to use for the pppoe connection. I believe that should be set to 'eth0' in this case. Try that and let us know how it goes.

Well, things run faster when all drivers are built into the kernel, but when doing testing, it's often
easier to build it as a module, and then you can insert and remove the module for your tests instead
of having to constantly rebuild the kernel and reboot the machine to test a new config. Just a thought.

No problem... Of course, not having that logfile won't kill the ability to make a connection. It just cut
part of your resources for solving the problem quickly. It still seems odd that there is no
/var/log/messages file. If your current metalog config file is based off of the example that comes
with it, I might recommend that you make a link like:
| Code: | | ln -s /var/log/important /var/log/messages |
Many applications in linux expect to see a /var/log/messages file for at least critical errors, as we just
saw in that debug output with 'adsl-start' above. So, point them in the right direction...
Hope that helps.

The application is telling you that the device you are trying to set PPP up on cannot handle
PPP. Take a look at what I wrote about the 'pty' error above.
HTH.
