Hi there, we have FreeRadius 2.1.12 installed in our lab mostly for testing purpose of our nodes. Now we have started to evaluate CoA on FreeRadius for both scenarios: a) Receive CoA packets from Node b) Send CoA-Requests to node (and analyze CoA-Ack, CoA-Nack Reading through several pages i always found "radclient" with the option "coa" to send/initiate CoA-Packets. And some of my colleagues (development) also use radclient for this purpose. BUT if i look at our radclient (v2.1.12) the coa option is missing there ? Last login: Sat May 5 15:17:27 2012 from dhcp-10-61-100-168.cisco.com [freeradius@sca-radius ~]$ radclient Usage: radclient [options] server[:port] <command> [<secret>] <command> One of auth, acct, status, or disconnect. Is it possible that this coa option was removed with v2.1.12 (or earlier) ? If yes, is there an alternative to send CoA packets from FreeRadius server ? I don't want to send CoA packets as a follow up to Access Request packet, but want to start it from FreeRadius. Many thanks for any helpful feedback, Thorsten
