Hi, I'm going to setup Freeradius CoA Virtual Server, I have already gone through originate-coa document, but need some help. This is the way that I traditionally originate CoA or POD packets: - I have wrote a Perl scripts that it listens on port 1810. - when I want to disconnect a user , I use another script to get user session info from DB , and then send it's information (User-Name, Acct-Session-ID, NAS IP Address) to port 1810 - then simply my perl scripts generates radclient commend and sends it to appropriate NAS. For the CoA it's same , the only different is that I send more AVP's to my script. Now what I couldn't understand is that, How should I trigger CoA server to send appropriate AVP's to NAS? How should I tell that I need these AVP's to be sent? I have Googled it but I couldn't find any sample. Thanks in advance. Regards, Nasser
