Hello Rani,
: i am currently now serving PPPoE in my area. i had a script
: generated from tcng that worked perfectly before i started
: serving PPPoE. the issue is not in the script it self BUT in that
: "tc" code is not shaping on the ethernet anymore BUT INSTEAD on
: the pppX devices. I tested it and talking jargon, what should i
: do?
:
: The issue is that for each PPPoE login, PPPoE-server creates on
: the server a pppX device. that is 10 logins means 10 ppp devices.
: from ppp0 till ppp9. and one might die upon disconnection.
I'd suggest simply using the pppoe ip-up configuration scripts to
call the appropriate tc or tcng commands. Since ip-up should be
called something like this:
ip-up ppp0 $TTY $SPEED 192.168.0.4 10.0.0.4 $OTHER
Is ip-up called by YOUR pppoe-server binary? I am not able to test
this.
you should be able to create a script that would either execute tc
commands or a create tcng file on the fly. I created the basic
structure of such a script below, although you could probably
add/replace your own shell functions (tc_sfq, tc_my_complex_config)
with a much more complex traffic control configuration.
Good luck,
-Martin
