Hello, This morning I was attempting to move dialup (PPP) authentication to FreeRadius, and was met with a segmentation fault. I am using version 2.2 on RHEL. Below are details of my configuration. Users are using MSCHAPv2. /etc/raddb/users DEFAULT Framed-Protocol == PPP, Proxy-To-Realm := DIALUP_REALM /etc/raddb/proxy.conf realm DIALUP_REALM { virtual server = dialup } /etc/raddb/sites-enabled/dialup server dialup { authorize { files mschap pap } authenticate { Auth-Type PAP { pap } Auth-Type MS-CHAP { mschap } } post-auth { #20+ group checks via LDAP } } In this configuration, I get a segmentation fault. It occurs before the mschap module is called in the authenticate stanza. (I cannot provide debug at this time, since I am outside the service window.) If I remove the manual proxying from the users file, the default server will handle the request fine. The default server looks like this: authorize { preprocess chap mschap files suffix eap { ok = return } expiration logintime pap } authenticate { Auth-Type PAP { pap } Auth-Type CHAP { chap } Auth-Type MS-CHAP { mschap } unix eap } Finally, if I put the manual proxy back in, and mirror the default server in my dialup virtual server, the seg fault returns. Any ideas would be appreciated. Dave
