Hello there,
I'm currently setting up FreeRADIUS as authentication/authorization backend for a PPPoE Server running with the ppp Daemon. I've managed to get the ppp Daemon to work with my working FreeRADIUS 1.0.3 Server but now have to solve another problem. Is it possible to limit the bandwidth the ppp channel allocated via an attribute in FreeRADIUS?
Or has someone another Idea how to manage a bandwidth cap?
What kind of OS this PPPoE server is running?
The Server is running on Linux (Debian 3.1 Sarge/stable)
If it is Linux/*BSD you can execute commands on session initialization ( /etc/ppp/if-up or something like that ). Just put some tc/altq/ipfw commands there...
btw: Search for "WARTA project" on google ;)
Hello there, thanks for the Info I will gather Information about WARTA and iproute2. But another problem should be that I have to control the bandwidth limits individually for each user logging into the pppoe-server. Sincerely, Sebastian Mauer

Ok.

So use HTB ( or HFSC ) for that, just create a new qdisc/class/filter for every user that connects to your concentrator. ---internet(eth0)--- linux --- pppoe_clients(eth1)---- What you should do: + prepare kernel with IMQ ( it's one of the possbile solutions ) + attach imq0 to ppp+ ( now all traffic outgoing on interfaces pppX will go through imq0 ) + before pppoe-server starts, attach htb/hfsc qdisc root to eth0 and imq0, prepare classes etc. + launch pppoe-server + write scripts (if-up/if-down) that create/destroy classess/filters/qdiscs on a) eth0 ( limiting upload ) b) imq0 ( limiting download for client ) + tune your setup ;) ( the info about bw limits could be fetched from RADIUS server using additional atttributes ) But first you should understand QoS on Linux deeply. Ask google for: lartc htb imq BTW: This group is not intended to ask question about Linux QoS and rp-pppoe. If you have trouble doing this i advice using FreeBSD as showed in WARTA HowTo. -- Jakub Wartak -vnull FreeBSD/OpenBSD/Linux/Network Administrator
