Description Stas V. Shimov 2004-11-06 04:37:09 EST
Description of problem:
When activating pppoe link adsl-connect script remove default route
from main routing table. This happened even when DEFROUTE in
ifcfg-pppX set to "no". Why it remove default route??? (Mistake in
adsl-connect script) As only new connection have been established and
ifup ppp0 finished, old default route is setting back as it was before.
If it can't set connection ifup exit, but default route stay removed.

Version-Release number of selected component (if applicable):
rp-pppoe-3.5-14.i386.rpm

How reproducible:
always happened

Steps to Reproduce:
1. Set some default route, 
2. adsl-config to configure new adsl connection
3. Edit ifcfg-ppp0 and set DEFROUTE=no
4. ifup ppp0 and while it is not returned watch your routing table.

  
Actual results:
default route removed

Expected results:
Default route is stay as was set and any actions with adsl interfaces
(that do not used as default route) do not have to influence on it.

Additional info:
Here is the patch

Fedora Core 2 is now maintained by the Fedora Legacy project for
security updates only. If this problem is a security issue, please
reopen and reassign to the Fedora Legacy product. If it is not a
security issue and hasn't been resolved in the current FC3 updates or
in the FC4 test release, reopen and change the version to match.
Comment 2 Trevor Cordes 2005-09-27 12:40:50 EDT
This bug is still present, as of FC3 (and I'm guessing FC4).  It's very easy to
solve.  It cost me 3 hours of fudging until I realized it was a linux bug.  It
manifests itself whenever you have a pppoe link that has DEFROUTE=no, or, in my
case, when having 1 machine with 2 pppoe links, only one of which has DEFROUTE=yes.
