ADSL connection timeout problems with F7
Last modified: 2007-11-30 17:12:07 EST
+++ This bug was initially created as a clone of Bug #242634 +++
Description of problem:
Activating ADSL no longer appears to work in Fedora 7 after using
the same hardware in FC 3 to FC 6. There are continual timeouts and
the resulting connection is subsequently terminated.
Example errors from /var/log/messages:
pppd: pppd 2.4.4 started by root, uid 0
pppd: Using interface ppp0
pppd: Connect: ppp0 <--> /dev/pts/3
pppd: LCP: timeout sending Config-Requests
pppd: LCP: Connection terminated
pppd: LCP: Modem hangup
pppd: LCP: Timeout waiting for PADO packets
ADSL setup was done using /usr/sbin/pppoe-setup providing the same
data as in earlier versions of Fedora.
Full details of 2 people having the same problem (with debugging output
in 2nd report) are available at:
Version-Release number of selected component (if applicable):

For some reason, this problem has now been solved by just re-installing PPP
from the Fedora 7 install DVD. I.e.:
rpm -i --replacepkgs [path to ppp-2.4.4-2 RPM on Fedora 7 installation DVD]
Once that was done, adsl worked (i.e. no connection timeouts).
This solution was quite by accident. I originally slotted in the FC6 binaries of
pppoe and pppd in the hope they'd work, but accidentally deleted the original
F7 version of pppd requiring me to re-install it from DVD.
So I guess this can be closed...
UPDATE: I have the same problema described above (Bug #242634 (cloned here)),
but the solution sugested in original bug report don't work.
A work-around was possible booting the _non_ Xen kernel, in my instalation the
Xen kernel was default.
Probably some investigation still needed...
I have to run a fedora - based router inside a paravirtualized domU under xen,
so I can not just switch to a non-xen kernel like many others do and have to
temporary switch another guest os. Below is what I was able to figure out
regarding this problem.
1) problem happens if xen kernel is used (e.g. 2.6.20-2925.11.fc7xen)
2) problem does not depends on ethernet configuration. I've tried to run pppoe
client on dedicated ethernet interface in dom0 and domU, on bridged interface.
3) If I look at the network exchange with a sniffer program, I see that PADI
requests are sent successfully and pppoe server responds to the requests
correctly. However pppd feels like it never receives any response.
4) If I run the tcpdump under the xen kernel I never see the pppoe exchange and
when I do it under the non-xen kernel I see it.
Hope above items can be useful.
I'm having the same problem. I'm running the xen kernel in dom0, and I haven't yet
been able to get an adsl connection, after configuring by running "pppoe-setup"
and entering the same settings as I used in fedora core 6 for "adsl-setup". I
haven't tried booting the non-xen kernel and repeating the attempt (for now I've
gone back to using fedora core 6).
Same issue here. At the moment there seems to be no way to have both xen & adsl
up and running.
Booting with xen enabled kernel (2.6.20-2925.11.fc7xen -64Bit-) doesn't allow
ppp to connect (timeout).
Booting with non-xen kernel (2.6.21-1.3228.fc7 -64Bit-) with the same ppp
settings confirmed to work.
I am not sure whether this is obvious, but: the problem is not restricted to
the dom0 but also arises when a domU runs on Fedora 7 and tries to connect to a
adsl modem via a dedicated network card.
Centos 5.0 and Fedora Core 6 both do not experience this problem.
Tested with the new 'kernel-xen-2.6.20-2925.13.fc7'... no luck
