Hi, I'am having trouble to authenticate my linux workstations with wpa_supplicant to Freeradius (1.1). The Windows Stations are working fine, but linux is making trouble. The AP is a Linksys WLAN Accesspoint, as said WPA Radius works, because all Windows Notebooks can login. I'am doing a WPA over EAP. And my Error is: Error: rlm_eap: Either EAP-request timed out OR EAP-response to an unknown EAP-request After switching on my debug I see this: rlm_eap: NAK asked for bad type 0 rlm_eap: Failed in EAP select Which is most certanly the reason why the auth fails. But I'am far away from knowing the solution. Can you help please?
