Hello, I have a problem with radwho since I upgraded from 2.1.10 to 2.2.0. The same configuration (I'm trying now the default configuration installed from ubuntu packages) works with version 2.1.10 and not with 2.2.0. The error I get is; radwho: No configuration information in radutmp section of radiusd.conf My config (for default virtual server) is: authorize { preprocess chap mschap suffix eap { ok = return } unix files expiration logintime pap } authenticate { Auth-Type PAP { pap } Auth-Type CHAP { chap } Auth-Type MS-CHAP { mschap } unix eap } preacct { preprocess suffix files } accounting { detail unix #radutmp attr_filter.accounting_response } # Session database, used for checking Simultaneous-Use. Either the radutmp # or rlm_sql module can handle this. # The rlm_sql module is *much* faster session { radutmp # # See "Simultaneous Use Checking Queries" in sql.conf # sql } post-auth { exec Post-Auth-Type REJECT { attr_filter.access_reject } } pre-proxy { } # # When the server receives a reply to a request it proxied # to a home server, the request may be massaged here, in the # post-proxy stage. # post-proxy { eap } I have tried it enabling and disabling radutmp in accounting section. As I have already said, this same configuration works with 2.1.8 (default ubuntu package) but not with 2.2.0. Any idea? -- Angel L.
