Description Peter Bieringer 2002-02-20 14:48:35 EST
From Bugzilla Helper:
User-Agent: Mozilla/4.78 [en] (X11; U; Linux 2.4.17-0.13 i686)

Description of problem:
I've recompiled pppd to use the FILTER option. Working great, but I cannot
specify extended filter configuration, because they have to be between single
quotes which isn't supported by the scripts.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
Working example:
PPPD_EXTRA="active-filter outbound"

Not working example:
PPPD_EXTRA="active-filter 'outbound and not icmp[0] == 3 and not tcp[13] & 4 !=
0'"



Actual Results:  Error message in log is
Feb 17 16:58:14 gate pppd[28416]: error in active-filter expression:
illegal char '''


Additional info:

I've debugged around in the script "adsl-connect", but didn't succeed.

The problem is somewhere around:

$SETSID $PPPD $PPP_STD_OPTIONS $DEMAND &

Putting the $PPP_STD_OPTIONS between " didn't help too, because now
pppd treats this all as one option.

It's a bug in ppp.
Comment 2 Peter Bieringer 2003-12-09 20:40:42 EST
Thanks to hints in bug
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=71247

this issue can be solved easily:
1) activate filtering in pppd (see also https://bugzilla.redhat.com/bugzilla/show_bug.cgi?
id=71247)
2) create a file  /etc/ppp/options.adsl containing e.g.
active-filter 'outbound and !(udp dst port ntp || udp dst port 3740)'
3) specify usage of this file for additional options in e.g.
/etc/sysconfig/network-scripts/ifcfg-ppp0 by
PPPD_EXTRA="file /etc/ppp/options.adsl"

Voila.
