Re: PPTPD Bandwidth Shaping

9 Jun 2009

      Hi all again,

Ok, I've got WISPr-Bandwidth-Max-Down in /var/run/radattr.ppp0 but the value is all wrong.

I set WISPr-Bandwidth-Max-Down = 512000 (as a reply)

and in /var/run/radattr.ppp0 its show as - WISPr-Bandwidth-Max-Down -1062731706

I just basically copied the dictionary.wispr to /usr/share/radiusclient-ng as in order to get it loaded in radattr.ppp0 :-

[root@xxx radiusclient-ng]# more dictionary.wispr
ATTRIBUTE       WISPr-Location-ID                       1       string
ATTRIBUTE       WISPr-Location-Name                     2       string
ATTRIBUTE       WISPr-Logoff-URL                        3       string
ATTRIBUTE       WISPr-Redirection-URL                   4       string
ATTRIBUTE       WISPr-Bandwidth-Min-Up                  5       integer
ATTRIBUTE       WISPr-Bandwidth-Min-Down                6       integer
ATTRIBUTE       WISPr-Bandwidth-Max-Up                  7       integer
ATTRIBUTE       WISPr-Bandwidth-Max-Down                8       integer
#ATTRIBUTE      WISPr-Session-Terminate-Time            9       string
#ATTRIBUTE      WISPr-Session-Terminate-End-Of-Day      10      string
ATTRIBUTE       WISPr-Billing-Class-Of-Service          11      string

Any ideas please.

Thx
Nev

  Hi Chuan,

  Thx for reply amongst this heated discussion on DHCP....

  I've currently got install freeRadius 2.1.6 and Poptop 2.4.4 and I see no dictionary file in /etc/ppp/radius/dictionary. In fact I have no radius directory in /etc/ppp

  All freeradius dictionary's are located in /usr/share/freeradius....

  The question is, how can I pass WISPr-Bandwidth-Max-Down to ip-up.local as I was hoping it would be in in /var/run/radattr.pppX, but all thats in there is:-

  Framed-IP-Address 192.168.0.70
  Session-Timeout 1646690
  MS-CHAP2-Success 7S=A8CF4948283C1C4BE11682787ADBD0EA9852E691

  MS-MPPE-Encryption-Policy 
  MS-MPPE-Encryption-Types 

  However we can see WISPr-Bandwidth-Max-Down being sucessfully passed to FreeRadius?

  ++[exec] returns noop

          NAS-Port = 0
          Acct-Delay-Time = 0
  +- entering group preacct {...}
  ++[preprocess] returns ok

  I would love to use WISPr as suggested, but cannot find out how to get this to work.

  Currently I've just defaulted EVERYONE to the same bandwidth restrictions by using the follow script in /etc/ppp/ip-up.local

  ip-up.local

  UPSPEED=768
