Hello, We have been experiencing a weird crashing problem with FreeRadius 1.1.7 on fedora core 7 and was hoping someone would be able to help. The problem is that FreeRadius will crash several times each day and before each crash this error is displayed. error: rlm_eap: Either EAP-request timed out OR EAP-response to an unknown EAP-request Here is part of the log file Thu Jun 26 08:12:27 2008 : Auth: Login OK: [BaiE/<no User-Password attribute>] (from client localhost port 0) Thu Jun 26 08:12:27 2008 : Auth: Login OK: [BaiE/<no User-Password attribute>] (from client 10.0.1.11 port 50405 cli 00-08-74-CB-78-BA) Thu Jun 26 08:13:22 2008 : Error: rlm_eap: Either EAP-request timed out OR EAP-response to an unknown EAP-request Thu Jun 26 08:13:22 2008 : Auth: Login incorrect: [MooresJ/<no User-Password attribute>] (from client 10.0.1.11 port 50108 cli 00-18-8B-79-91-9B) <restart FreeRadius> Thu Jun 26 08:18:20 2008 : Info: Using deprecated naslist file.

Upon restart of the demon, it will then successfully authenticate the same user without crashing. FreeRadius is communicating with Active Directory to authenticate users. Thanks, Kyle
